Introduction

After many months and years of planning, and 20 years after Habitat II, Habitat III is a reality. As befits a gathering that happens only every 20 years, its goals are ambitious—there’s a lot to do. There is potential reward and risk, potential hope and disappointment built into the fiber of a convening such as Habitat III. Its grand gestures could inspire a vision that propels countless people to enact that vision on the ground in cities around the world. Or, the distance between metaphorical flourish and actionable agenda could be too great for implementation. The immense congress of urbanists, humanists, civil society, academia, people from government, practitioners—45,000 in all—might create an ambitious and specific vision for urbanization that serves humanity well. Or, such a sprawling group might file away all the sharp and controversial edges, producing a “vision” that is both bland and toothless. Bland and toothless will not serve us well, given the broad challenges to resilience, sustainability, livability, and justice around the world.

So Habitat III is a heavy lift, and the weight of the (urban) world lies across its broad shoulders. Everyone who has invested in Habitat III is to be celebrated and offered a hearty  “Thank You”.

Habitat III has an outcome document. It hopes that heads of state and government commit to an urban paradigm shift for a New Urban Agenda grounded in the integrated and indivisible dimensions of sustainable development: social, economic, and environmental. This New Urban Agenda [is adopted] as a collective vision and a political commitment to promote and realize sustainable urban development, and (…) a historic opportunity to leverage the key role of cities and human settlements as drivers of sustainable development in an increasingly urbanized world. 

In this roundtable, we want to focus the hope—for outcomes of Habitat III, as opposed to its outputs. Many, or even most, of the agenda’s outcomes won’t be known or evaluated for years. So, we’ve asked a group to project what they think the most important one is. As one might expect, the responses are diverse. Justice, equity, and housing are mentioned often. Better governance and increased capacity are key. Several of our contributors discuss the need for integrating the urban-rural gradient into a landscape concept that avoids false and unhelpful dichotomies.

The marriage of social, economic, and environmental is important in the Habitat III outcome document, and this is reflected in the responses here. The future of cities isn’t only about sustainability, or housing, or resilience, or indeed about any single thing. It is about finding a mix of social, economic, and ecological goals, and find a way to act on them.

Exactly how to act, and who will act, remains one of most difficult aspects of Habitat III: getting from vision to action.

The New Urban Agenda in the new UN

The New Urban Agenda kicks off a 2-year process under the authority of the UN Secretary General and the UN General Assembly to define its modalities of follow-up and review. This process will overlap with the expected UN-wide reforms under the new UN Secretary General—who will take the office on 1 January 2017.

The New Urban Agenda will pave the way for developing a new model of collaboration and engagement of the local and subnational governments in the UN system.

Both of these processes will be designed for and implemented in a world that is more urbanized and connected than ever before. Thus, both follow-up and review of the New Urban Agenda and the UN reform, in practice, will focus on defining a new concept for the UN system and ways for its Member States to engage with local and subnational governments, as their role in the implementation and advancement of global sustainability goals become even more crucial.

Sustainable urban development: evolution beyond the HABITAT Agenda

The period between 1972 and 1976, starting with the Stockholm Conference on Environment and ending with the Vancouver Conference on Human Settlements, was the first cycle of intergovernmental efforts that laid out the foundations for sustainability within the UN system. The second phase, from 1992 to 1996, starting with the Earth Summit in Rio and ending with HABITAT II in Istanbul, defined the basic principles of sustainable development.

During the implementation of this second phase, the scope and focus of the HABITAT Agenda was relatively narrowed down as its mission was reoriented in response to the Millennium Development Goals, which decoupled it from the rest of the sustainability agenda. The Habitat Commitment Index by the New School is recognized as one of the key indices that assesses progress in this period. Meanwhile, thousands of locally driven sustainability planning, consultation, and implementation processes have been nourished in this period, building on the spirit of Local Agenda 21, and stemming from the Earth Summit held in Rio in 1992. These ambitious and progressive actions on the ground have yielded fruits, resulting in key achievements relating to the engagement of local and subnational governments in numerous UN processes on climate change, biodiversity, and procurement in particular.

The New Urban Agenda: bringing urban development back to the sustainability agenda

In the broadest terms, HABITAT III was expected to conclude the third phase of these intergovernmental efforts, which started with Rio+20 in 2012. In fact, the HABITAT Agenda was already reflected into the universal Sustainable Development Goals adopted in 2015 through Goal 11, which focuses on making cities and human settlements inclusive, safe, resilient, and sustainable—goals which are almost identical to paragraph 1 of HABITAT II in 1996. However, it was not possible to enshrine a clear linkage between SDGs and HABITAT IIII until the last hours of the informal session in September. Luckily, paragraph 9 of the Quito Declaration finally foresees that the New Urban Agenda will localize the 2030 Agenda for Sustainable Development in an integrated manner, and contribute to the achievement of the Sustainable Development Goals (SDGs) and targets, including SDG 11”. Together with paragraphs on follow-up and review, it is now possible to confirm that the New Urban Agenda is a core element in this third phase of the sustainability agenda, which is expected to be more holistic, transparent, inclusive, and transformative.

The New Urban Agenda in the making of the new United Nations of the Urban World

Pursuant to the recognition of the enormous need, potential, and power of local and subnational governments to support national and global efforts, almost all UN agencies now have some sort of a project, programme, or initiative focusing on cities and regions. The Executive Office of the UN Secretary General is also advancing its support by expanding the Subnational Climate Action Hub, initiated at the Paris Climate Conference in December, to all SDGs and relevant stakeholders.

Therefore, the implementation of a 2-year consultation indicated in paragraphs 171 and 172 of the New Urban Agenda may easily be expanded to all members of the UN system, pursuant to the leadership of the UN Secretary General and the UN General Assembly in the process. This will include an assessment of UN-Habitat commissioned by the UN Secretary General, which will be followed by a high level meeting at the UN General Assembly in 2017, and conclude with a decision of the UN General Assembly in 2018. It is hoped that the process will have strong interactions with some other events in 2017 (such as the UN-Habitat Governing Council in April, the UNFCCC stakeholder engagement workshop in May, and the 3rd UN Environment Assembly in December) and in 2018 (the World Urban Forum in February, the IPCC cities conference in March, and a High Level Political Forum focusing on SDG 11 in July.)

It is obvious that these consultations will go hand-in-hand with the expected UN reformed agenda under the new UN Secretary General starting in 2017. In the Urban World of 2030, appropriate utilization and vertical integration of the potential, ambition, and power of the local and subnational governments is key to ensuring successful attainment of any global goals and national commitments. Thus, one of the biggest outcomes of the New Urban Agenda will, in fact, be to pave the way for developing a new model of collaboration and engagement of the local and subnational governments in the UN system. If this process delivers the necessary innovations, it will be considered the biggest legacy of HABITAT III.

With the UN Habitat III Conference in less than a week, the levels of excitement and expectation among those working in or on the cities—urban policymakers, practitioners, and researchers worldwide—are high. According to the organizers, more than 35,000 participants already registered and will come to Quito, Ecuador, to discuss and adopt the New Urban Agenda, which aims to set global standards for achieving sustainable urban development. Cities and urban affairs are likely to receive national and international political attention, and even become the focus of the world’s mainstream media—at least for the next week or two.

Habitat III won’t be a success unless the attention it garners urban issues can be converted into societal momentum to achieve the New Urban Agenda.

For many, the importance of achieving sustainable urban development is a no-brainer—urban futures will largely determine human futures, and the window of opportunity to improve urban futures sustainably is here and fast closing. However, this sense of importance and urgency is not necessarily shared beyond traditional urban centers. Too often, urban issues are still regarded as local issues, which can therefore be left in the hands of urban decision-makers and practitioners alone. Habitat III won’t be a success unless the attention it garners urban issues can be converted into societal momentum to achieve the New Urban Agenda.

A new and much broader engagement of stakeholders in urban affairs is needed to create such momentum. I will highlight three aspects of such engagement here. First, effective involvement of national governments in urban affairs is essential. Although they have administrative boundaries, cities are regional, national, and global in terms of the extent of their connections, processes, and impacts. This scope of influence needs to be matched by a policy framework that reflects this nature of cities. Giving cities their rightful voices in national and international policy forums; matching the mandates of cities with appropriate financial shares; providing, facilitating, and supporting policy and institutional environments by upper level governments—but at the same time not overpowering or dictating, and leaving the room for cities to explore innovate their own paths—are essential. The New Urban Agenda rightly recognizes many of these, with multilevel government linkages emphasized in many places.

Second, active participation of the general public from all walks of life needs to be enabled and achieved. This entails both the “right” and the “responsibility” of the citizens. On the one hand, the needs of the urban poor and other marginalized populations—needs such as the access to food, clean water, basic infrastructure, and other services—should receive the highest political priority, and the right of citizens to cleaner air needs to be urgently tended to. On the other hand, active participation also means citizens taking responsibility for resources and the environmental consequences of everyday urban life and choices. Chai Jing, an investigative journalist in China, said in her immensely popular film titled “Under the Dome”, that “the smell of the smog is the smell of money”, and that each and every citizen is contributing towards it. Responsible actions must be taken by all, as many urban problems cannot be solved otherwise. The need to improve access to basic sustenance and services is well articulated in the New Urban Agenda, but it does not sufficiently address the problematic lack of clean air for all citizens.

Third, urban science and scientists need to be given stronger roles. Urban science and the research community have received very little attention in the drafts of the New Urban Agenda. Yet, just below the surface of almost every commitment, there is a question that needs to be answered by urban science, broadly defined.

For example, the New Urban Agenda aims to achieve its goals “by readdressing the way cities and human settlements are planned, designed, financed, developed, governed, and managed, the New Urban Agenda will help to…” do various things. But the real question would be, how will the New Urban Agenda achieve these changes? Promoting integrated spatial planning has been around for a long time, but why is it not a reality?

Underneath these concerns are the fundamental questions of how cities, as complex evolving systems, work, and how these systems are understood. The truth is, we don’t have a good understanding of how cities, as increasingly complex system, behave, which is the reason many of our policy interventions do not work as intended in practice. Unless urban scientists, policymakers, and practitioners actively work together to address these questions, interventions may not be able to address the real cause of the problems, and the New Urban Agenda may end up becoming another new year’s resolution that is never achieved.

All of the engagements I have discussed can only happen if the efforts are bidirectional.

The recently completed draft New Urban Agenda, the Habitat III outcome document, reaffirms member states’ support of planning and managing urban spatial development and, equally importantly, providing the enabling environment (a supportive governance and means of implementation—knowledge, capacity-building and finance) in which those activities can occur. It does so in each of its parts (the “Quito Declaration,” “Quito Implementation Plan for the New Urban Agenda,” and “Follow-Up and Review”).

The prioritization of place in the New Urban Agenda is the single most tangible outcome of Habitat III.

While the New Urban Agenda pursues these priorities with simultaneous and synergistic actions, the recommendations for planning have a specificity that provides a clear roadmap for public and private decision-makers to tailor programs to their particular environments. Thus, I believe that “place matters”, as seen in the detailed articulation of the physical characteristics of a place, is the single most tangible outcome of Habitat III.

Note that the NUA assumes that urban places will have to accommodate some 2.5 billion more residents in the near future and will need to offer opportunities for efficient and agglomerative economic growth and protection of the environment overall. Further, the NUA recognizes the economic value of well-planned places—a fundamental issue related to individual and collective prosperity, i.e., the ability of property owners to increase their own assets and of cities to experience robust productivity that would reflect their overall economic health.

So, let’s take a look at the elements of the roadmap that are in the New Urban Agenda, remaining mindful that while its recommendations reflect general principles related to achieving sustainable urban development, contextualization of the recommendations will be essential. That is: “The devil is in the details”, and this is where multi-stakeholder work is going to be essential.

For overall guidance, the NUA refers to UN Habitat’s Guidelines for Urban and Territorial Planning, adopted by the Governing Council in April 2015, and which outlines roles for spheres of government: national (e.g. connect and balance the system of towns and cities); metropolitan (e.g. regional economic development, rural/urban linkages, ecosystem protection); municipal (e.g. design and protection of citywide systems of public space, capital goods investments in basic infrastructure, overall block layout, connectivity); and neighbourhood (e.g. site specific design, local urban commons).

Throughout the documents the reader will find specific recommendation that include:

  • A strong call for implementing integrated, polycentric, and balanced territorial policies and plans (para 95), which entails national urban policies that frame the spatial development of a nation (para 89)
  • A statement on the importance of planned urban extensions and infill development as a means of protecting natural resources and ecosystem services in the surrounding territory, as a means of supporting compact development (para 51)
  • Within urban places, treatment of the key elements that make a place safe, inclusive, resilient, and sustainable
    • Housing: several paragraphs call for adequate and affordable well-services dwelling units for all (paras 99, 105-108, 140)
    • Transportation: several paragraphs that deal with multi-modal mobility call for efficient and equitable public transit, including instituting equitable transit oriented development (TOD) (paras 113-118, 141)
    • Public space and green open space: many references to having sufficient, accessible space for recreation, infrastructure (streets, water/sewer), and social and economic uses (paras 36, 54,67,100) .
    • Basic services: water and sanitation top the list (paras 34, 88, 119), but dealing with waste management is also noted to be of critical importance (para 74), as are the creation of building codes (111, 121, 124) for safety and resilience.
    • Heritage: appreciation of the value of cultural heritage as contributing to the social and economic lives of the residents and to environmental preservation is clearly articulated. Of note is its appreciation of the wide variety of the sources of culture (paras 38, 45, 60, 97, 125)

A roadmap is not sufficient without the political will to use it. In the coming years, the key challenge will be to energize, inspire, and convince the member states to undertake the necessary programs—and this is where stakeholders, such as those from the General Assembly of Partners and the Global Task Force, come in. Working in a multi-stakeholder partnership model, they can have a critical role in keeping awareness of the key elements of the roadmap present in the minds of their constituents and in the everyday business of national, regional, and local government. That is, they can monitor and advocate fiercely. Further, at all stages of implementation, they can help provide the knowledge to help guide the policy choices to be made by all spheres of government. One question remains: can stakeholders meet the challenge of working for the collective interest while still safeguarding their specific group concerns?

Balanced sustainable and integrated urban and territorial development: Key pillar for implementing the urban paradigm shift of the New Urban Agenda

When TNOC asked me what I thought was the single most important outcome of Habitat III, I instantly thought that reducing the competing forces and political factors that coexist in any intergovernmental process to one aspect was no straightforward task. One could even ponder if such reduction is convenient. Intergovernmental processes marked by 20-year cycles—such as the Habitat ones are—set global agendas that are the complex result of multilateral and geopolitical contexts.

Habitat III’s articulated aim to end the dichotomy between urban and rural areas is its most important vision.

Judging by the negotiation complexities the Habitat III intergovernmental process experienced in 2016, cynical souls could argue that getting to Quito with an outcome document ready for adoption by heads of state and government constitutes the single most important outcome of an intergovernmental process that, at moments, required much more soul-searching than what its “post-2015 context” had augured.

2014 and 2015 were prolific for multilateralism, with the international community adopting several global agenda-setting frameworks: the 2030 Agenda for Sustainable Development, including the Sustainable Development Goals (or SDGs), the Addis Ababa Action Agenda on Financing for Development, the Paris Climate Action Agreement, the Sendai Framework for Disaster Risk Reduction 2015–2030, the Vienna Programme of Action for Landlocked Developing Countries for 2014–2024, the Small Island Developing States Accelerated Modalities of Action (or SAMOA) Pathway. Could the international community in 2016—in a post-2015 multilateral context—give birth to yet another “paradigm-shift-pursuing” global framework? In the outcome document of the Habitat III Conference, heads of state and government commit to an urban paradigm shift for a New Urban Agenda NUA (Para 5*) grounded in the integrated and indivisible dimensions of sustainable development: social, economic, and environmental (Para 24). This New Urban Agenda (is adopted) as a collective vision and a political commitment to promote and realize sustainable urban development, and (…) a historic opportunity to leverage the key role of cities and human settlements as drivers of sustainable development in an increasingly urbanized world (Para 22).

Whether in 2016—in the post-2015 multilateral context—the international community needed yet another long list of “paradigm-shift commitments” narrated primarily using previously agreed upon, multilateral language; or whether, alternatively, these noble aspirations begged for specific, measurable, action-oriented, realistic, and time-based implementation plans is another question. In any case, the recognition of the potential contributions of urbanization to the achievement of transformative and sustainable development (Para 4) delves deeper into the historic inclusion of SDG #11, “to make cities and human settlements inclusive, safe, resilient, and sustainable” in the 2030 Agenda for Sustainable Development. We should warmly applaud this outcome and commend all the stakeholders who have made it possible.

After this very long introductory disclaimer and pushing myself to identify the single most important outcome of Habitat III from a technical point of view, I would like to highlight the vision for cities and human settlements that fulfill their territorial functions across administrative boundaries, and act as hubs and drivers for balanced sustainable and integrated urban and territorial development at all levels, contained in Paragraph 13.e of the Habitat III outcome document.

Urbanization and demographic growth have increasingly linked cities with their peri-urban and rural areas spatially as well as functionally, through interdependent economic dynamics, social links, and environmental synergies that overcome traditional administrative boundaries. Examples of systems for which an approach of complementary functions and flows across urban and rural spaces is needed include: supply and distribution chains of commodities and services systems (raw materials; manufactured goods; basic services such as water and electricity; financial services such as financing and insurance; or ecosystem services such as water production, air quality control, energy generation, etc.); social protection systems, including health, education, diets and nutrition; transport systems, including the infrastructure for short and long chains; food production systems, including linking urban, peri-urban and rural production; land tenure systems, including formal legal and customary tenure systems; market systems that connect producers to consumers through formal and informal channels; disaster risk reduction and risk management systems, and governance and decision-making systems.

The notion of balanced sustainable and integrated urban and territorial development can contribute greatly to the objective of equitably distributing, across the wider urban-rural continuum, the gains brought by the process of sustainable urbanization. This notion is important in achieving inclusive, climate-friendly, environmentally friendly, resource-saving, and resilient development that addresses the needs and demands of both urban and rural areas. It also promotes integrated planning instruments, cross-sectorial solutions, and systems thinking in areas such as water, energy, and food security, as well the transport and waste sectors. This concept also encourages urban density and mixed land use and contributes to securing public and green spaces, as well as to preserving biodiversity. It promotes comprehensive risk analyses as a generalized starting point for resilient urban development, as well as requiring land use planning and spatial strategies that address flows across urban and rural landscapes. Accordingly, governance and decision-making systems have to be aligned vertically and coordinated horizontally, involving actors from different levels of government—national, regional, local and municipal—and different sectors—local communities, civil society, business, science and academia, philanthropies—to reduce conflicts around the use of limited resources and facilitate the balancing of interests. All in all, balanced sustainable and integrated urban and territorial development is a departure from myopic sectoral and urban-only approaches to holistic, multi-disciplinary, multi-sector, and multi-stakeholder approaches at the city-region scale.

The Habitat III vision for human settlements that fulfill their territorial functions across administrative boundaries, and act as hubs and drivers for balanced sustainable and integrated urban and territorial development at all levels, represents a robust opportunity for governments at all levels, the UN system, practitioners, scholars, civil society, and all relevant stakeholders to harness this reinvigorated will of the international community to depart for once and for good from a perspective of political, social, and geographical dichotomy between urban and rural areas.

Renaissance of urban and territorial planning

Habitat III, its attendant global charter—the New Urban Agenda—and the concomitant commitment of the United Nations’ member states to it potentially act as a collective beacon for the renaissance of urban and territorial planning in the 21st century. The sine qua non for such a renaissance will be the long-term transformation of urban and territorial planning as an effective tool for sustainable urban and territorial development and management.

The renaissance of urban and territorial planning is long due for a number of interrelated reasons.

The renaissance of urban and territorial planning is long due for a number of interrelated reasons. First is the ever-increasing complexity of social, economic, and environmental challenges in the Anthropocene—reflected as they are in the 2030 Sustainable Development Agenda and the COP21 Paris Agreement, as well as the need to address them in an integrated manner. Second is the need to manage and accommodate the fast pace of urbanization in developing regions such as Africa and Asia; in Asia alone, over 40 million new inhabitants are added to cities and towns every year. Third is the unprecedented set of spatio-demographic challenges in cities around the world, including the development of mega-urban regions, the phenomenon of urban shrinkage, and cross-border cities—to name just a few. Fourth is the importance of sound public policy and decision-making that involves various stakeholders, whether they are social (gender, youth, aged, or differently-abled), environmental (indigenous groups, environmental activists, advocates of ecosystem-based approaches, and those who address biodiversity, natural disasters, climate change, and the like), financial (people-public-private-partnerships), research (academic and research institutions, and think tanks), and media (print, online, radio, television, and social media) groups. The fifth factor is the substantive and technical progress urgently required for equipping urban and territorial planning in order to balance short-term needs with long-term desired outcomes in sustainable urban and regional development.

Whilst the renaissance of urban and territorial planning is urgent and (some would say, absolutely) necessary, it will not materialize easily. To make it happen will require administrative, institutional, procedural (also, perhaps, legal), and technological transformation as well as scientific (including applied and action) research on six interconnected fronts.

First, inter-agency and intra-agency administrative separatism will have to be reduced, if not completely eliminated. Silo-based administrative processes (e.g. processes narrowly limited within a specific discipline) have done enough harm to sound urban and territorial planning, all of which has resulted in haphazard development. Silos will have to be broken down, or “silo-effect” will have to be reduced to minimum, in order to put in practice the idea of sustainable urban territorial development.

Second, vertical institutional integration will be essential for opening up the compulsory legal and/or procedural space for (more) efficiently integrated urban and territorial planning. This will require delegation of powers to the various tiers of government—including sub-national, district, city-level, and sub-city-level authorities, which will be necessary to avoid bureaucratic quagmires and issues that have plagued multi-level governance.

Third, horizontal inter-jurisdictional coordination will be a prerequisite for the success of urban and territorial planning, especially with regard to city-regional infrastructure, urban-rural linkages, natural resources and environmental management, ecological restoration, biodiversity conservation, and urban-regional integration. This will be particularly important in the case of city-regions, mega-urban regions, urban corridors, and cross-border urban regions. Such coordination will be particularly important for addressing inter-jurisdictional fiscal disparities that hold the implementation of innovative and sustainable solutions.

Next, there is an urgent need to develop integrated approaches to address social, economic and environmental challenges in the urban and territorial context. The on-going work on “co-benefits” of developmental activities is making progress in this direction. More efforts need to be made on this front to conceptualise, develop, and implement integrated approaches that could feed into and bolster the revamping of urban and territorial planning.

Fifth, an increasing use of smart city approaches will feature in the future of urban and territorial planning. Smart city approaches will range from (i) the more sophisticated ones, for instance, such as “Supervisory Control and Data Acquisition” (or SCADA), to (ii) smart city systems, which include smart people, smart city economies, smart mobility, smart environments, smart living, and smart governance, and (iii) smart analytical and decision-support systems, such as for (a) collection, collation, compilation, analysis, and visualization of data, (b) development, analysis, and comparison of planning scenarios, (c) supporting decision-making process(es), and (iv) monitoring and evaluation, and facilitating feedback loops.

Finally, an ever-expanding scientific knowledge will act as a kingpin in the revitalization of urban and territorial planning. Future scientific knowledge will need to take into account the lessons learnt from (i) the worldwide experience in “town and country planning” practised since the advent of the industrial revolution, (ii) the implementation of urban and regional planning within various countries, (iii) the practice of metropolitan and city-regional planning, and (iv) the development plans and programs for small- and medium-sized cities. The ever-expanding scientific knowledge will combine these lessons learnt with (i) local social, cultural, and ecological wisdom; (ii) traditional knowledge on human, social, and environmental well-being; (iii) indigenous knowledge; and (iv) local developmental experience, both good and bad.

All of these factors, as well as the challenges and opportunities yet unforeseen, and inventions and technological developments yet to be made, will act as guiding lights and building blocks for the renaissance of urban and territorial planning in the 21st century.

Let’s commit land for affordable housing

The single most important outcome of the Habitat III conference would be if all participating nations unequivocally agreed to commit land in their cities exclusively to construction of affordable housing (this does not come through in the draft of the “New Urban Agenda”, Habitat III’s outcome document). Thereafter, various governments would have to undertake direct responsibility for building affordable housing, rather than relying on markets for their supply.

Our collective focus has to shift to affordable housing alone, given the gravity of housing conditions in most cities.

The exclusion of more and more people from the benefits of development, particularly their access to formal and dignified housing, is squarely a failure of the current patterns of urbanization, which are steadfastly undermining the very idea of cities. Expanding cities are by no means indicators of desirable and sustainable urbanization. Achievement of higher human development standards, along with equity and justice for all, would be true indicators of successful urbanization and city-making efforts. Tragically, cities are being rapidly divided into disparate fragments of exclusive communities and marginalized populations. It is in this context that the Housing Question has to be understood and evaluated. Our failure to ensure this basic human right to a vast majority of city populations exposes our failure while challenging our collective capacity and capabilities.

The central issue in the housing question is land. Unfortunately, this statement has to be reiterated. The question that confronts us is, how do we achieve equity in land use and interweave the disparate fragments of our fast growing cities into unified landscape? We hope these questions are dealt with bluntly and squarely, and will lead to tangible outcome at the Habitat conference.

We hope the final declarations will overcome the overarching generalizations in the draft documents and will outline more specifically much-needed interventions for the equitable distribution of land and an increased role of governments in building affordable housing and amenities for all. However, the more daunting task will be to incorporate and reflect multitudes of local needs and demands into a set of common principles and action plans for the achievement of these objectives. While respective governments may put local plans together, it was agreed that one outcome of the Quito conference would be to collectively review, intermittently assess, and agree on individual cities’ and nations’ action plans for successful implementation of the global objectives.

Equity in land use

We have to bring land back to center stage in our discussion; over the years, as countries have committed to neoliberal globalization, the question of land has been pushed to the backstage. Substantial public land has been gifted away by governments and/or captured and colonized by private developers, who have been mandated to carry out development works, including public housing. Therefore, our questions related to just utilization of land are not being raised, as they would impinge on the freedom of free market forces. Such a model of development has not worked in favor of the public interest, nor has it contributed to the public good.

In many instances, without pledging land, governments have been beating around the bush, negotiating deals with private landowners and developers, who seeking concessions by dedicating a percentage of the built-up area in their high-cost projects towards affordable housing. Such a begging-bowl approach is only scratching the surface of this gigantic crisis that is crippling our cities and causing serious social unrest. On a related note, we also hope the outcome at the Quito conference formally calls off our increased dependency on markets for the promotion of affordable housing.

This exercise of allocating land for housing must not infringe upon the natural areas and ecologically sensitive zones and open spaces provision. Can the Habitat-III firmly resolve that all nations who are signatories commit to this significant step in the interest of checking climate change impacts?

But in many cities, large tracts of land are colonized and/ or occupied and contain very little vacant land. Poor and lower- middle class people, have managed to find roofs over their heads by living in slums and other informal settlements, often in very poor conditions. Slums have proliferated due to the non-unavailability of affordable housing. Can the present land occupation pattern— which is consistent with demand, although it is termed illegal or informal—, be accepted and formalized by incorporating these settlements into the development plan of cities? Reserving slum land in the development plans of cities would be one way of gaining land for affordable housing.

Focus on affordable housing

Currently, the Habitat declaration merely specifies the need for governments to allocate land for housing. This is too general; it is rather weak as a proposition, given the current situation of land in cities. We know that land earmarked for housing has been taken over and exploited almost entirely for exclusive upper class housing, high-cost amenities, and commercial development. Therefore, land has to be more specifically reserved for affordable housing. It is time that we collectively resolve under the UN Habitat III banner that “Housing” be re-addressed, or rephrased as “Affordable Housing” in all our discussions and documents. Our collective focus has to shift to affordable housing alone, given the gravity of housing conditions in most cities. Let the rich and those who can afford to buy or rent on the open market continue to rely on private builders and developers to fulfill their desires. We need not invest our collective time and resources to facilitate them.

We hope the UN Habitat III conference resolves that governments of all participating nations agree to commit adequate land to and will actively undertake the development of affordable housing and amenities, for the achievement of just, equal, and sustainable cities.

The most significant global goals for the coming decades can only be achieved through major changes in the way that cities (and their governments) function. Reaching the Sustainable Development Goals (or SDGs) and meeting the commitments of the Paris Agreement on climate change will require new approaches to urban governance, greater technical and financial capacity for local authorities, and a stronger recognition of the role for local civil society both in implementing activities and in holding governments to account. Cities around the world need to be at the forefront of combining high quality living conditions, resilience to climate change, disaster risk reduction, and contributions to mitigation / low carbon development.

For the New Urban Agenda to achieve meaningful outcomes, it needs the right ingredients, political astuteness, and appropriate data.

The New Urban Agenda does not need to develop a comprehensive list of goals and commitments—this already exists in the SDGs and in the Paris Agreement. The single most important outcome from the Habitat III conference in Quito should be a recognition of the (mostly local) actions that need to be taken to achieve these goals, and a commitment by national and local governments to work in meaningful partnership with civil society groups to implement them.

What will determine the significance of this new urban agenda is its relevance to urban governments and urban dwellers, especially those whose needs are not currently met. This means that it has to be clear and relevant to the billion or so people living in poor-quality housing (mostly in informal settlements) with inadequate provision for basic services. It needs to be relevant to mayors, as well as to other urban politicians, civil servants, and other civil society groups. And what it recommends has to be within their capacities. It will have to go far beyond the SDGs, which are full of goals and targets (i.e., what has to be done), but which are very weak on how, by whom, and with what support those goals and targets should be achieved. The UN member states participating in Habitat III will have to focus on building or strengthening the institutional, governance, and financial frameworks.

There are lessons that can be learnt from “new urban agendas” of the past. Several of these, including the Healthy Cities movement, Local Agenda 21, participatory budgeting, Making Cities Resilient, and the Carbonn Climate Registry, have focused on urban areas. They included clear, simple, and relevant guidelines that got buy-in around the world. Their success was due in part to their encouragement of local actions that were relevant to local governments and supported by many urban residents. Even more significantly, the presence of a growing number of federations of slum/shack dwellers has changed the way in which urban development takes place. Such organizations are now present in more than 30 countries, where they build or improve housing, undertake surveys of informal settlements, and provide sanitation—and do this through working with local government (which allows a much larger scale of impact). This type of relationship between representative organizations of the urban poor and elected local government representatives can be genuinely transformative.

For the New Urban Agenda to achieve meaningful outcomes, it needs:

  • The right ingredients: a vision that ties prosperity with inclusion, which links organized low-income groups with others who benefit from public goods and services, and which addresses both environmental sustainability and resilience.
  • Political astuteness: removing discriminatory exclusion, ensuring that prevailing institutions support the Agenda, and ensuring that human rights are fully met.
  • Appropriate data: indicators to monitor and report progress, that are sufficiently geographically disaggregated to be relevant for local governments local civil society and that record meaningful information about issues shaping the lives of urban residents.

In summary, then, for the New Urban Agenda to achieve tangible outcomes, it needs to be concise and clear, to focus on the implementation of goals, and to recognise the importance both of competent and effective urban governments and of getting the buy-in of urban residents, including those living in informal settlements. If this can be achieved, then there is a genuine chance for transformative change for cities and citizens in the 21st century.

A new urban landscape approach

HABITAT III is the first major conference of its kind since the establishment of the Post-2015 Development Agenda, so one of its major roles must be to guide the urban development agenda into line with the priorities of the new overall development agenda. Reconciling these two agendas, so that those of us working in urban issues and those of us working in other conservation fields are not working at cross purposes, will be key to achieving both the goals of the draft New Urban Agenda to be adopted in Quito and the Sustainable Development Goals (or SDGs) related to urban issues.

Habitat III should cultivate landscape approaches to bring the urban agenda in line with conservation and post-2015 development goals.

So, what aspects of the development and conservation agendas need particular attention in the coming urban agenda? I’m sure each of the respondents to this roundtable will have specific points they would like to see included; my own would be the concept of the “landscape approach”. Landscape approaches have gotten a lot of attention in recent years in both conservation and development fields as a way of reconciling the seemingly competing priorities of each.

“Landscape approach”, in the sense that I am using it here, refers to the management—both conservation and use—of resources at the landscape scale. In many cases, management approaches have been based on one or more sectors, such as manufacturing or tourism, which can result in short-sighted management, inequalities, and perverse incentives—and, therefore, unsustainable use of resources. Other approaches, especially where public policy is heavily involved, are often based on administrative boundaries that have become out of date in terms of how and where people actually live and work, and, therefore, how and where resources are located, produced, and consumed. Landscape approaches, such as those promoted through the Satoyama Initiative—my main area of work here at UNU-IAS—attempt to take a holistic view of the landscape, integrating the interests of all sectors, administrative bodies, producers, consumers, and other stakeholders as much as possible. For this purpose, the “landscape” is defined as a logical unit constituting the area in which resources are used and managed by a local community or communities, for example. This could be a watershed, an administrative boundary, or something else, depending on the delimiting barriers and internal mechanisms for resource management.

The draft New Urban Agenda only contains the word “landscape” two times, but both serve to highlight ways in which landscape approaches can apply to urban issues. The first mention of landscapes is about the creation and maintenance of networks of public spaces in order to promote “attractive and livable cities and human settlements and urban landscapes, prioritizing the conservation of endemic species” (this is a nice little shout-out to “the nature of cities”, too). This mention of “urban landscapes” points to an urban area constituting a “landscape”, or collection of landscapes, in itself. In this sense, a landscape approach to urban areas would mean planning and policymaking that account for the interests of all stakeholders in this landscape. This would avoid problems related to the narrow interests of certain sectors, or the particular concerns of people who happen to live within certain administrative boundaries, potentially reducing inequalities and contributing to more fulfilled lifestyles for all.

The second mention of “landscapes” in the New Urban Agenda document is about safeguarding “a diverse range of tangible and intangible cultural heritage and landscapes”, to “protect them from potential disruptive impacts of urban development”. This hints at another kind of urban landscape approach, taking a wider view of the larger biocultural landscape, with urban areas included as just one landscape element, and the need for better integration of cities into the landscape. Cities naturally depend on the surrounding landscape for provision of a wide variety of resources and ecosystem services; likewise, rural and peri-urban areas depend on the city as a market for products and as a provider of services only found in urban areas. Despite these symbiotic relationships, planning and policy too often seem to pit urban and non-urban against each other so they end up competing for resources and other benefits. A landscape approach that considers the urban area as a vital part of the wider landscape can help to overcome this tension.

That said, the solution is not necessarily that the “Quito Declaration” and “Quito Implementation Plan” need to contain the word “landscape” more often, but rather that landscape approaches and a holistic perspective on the wider landscape should be adopted as part of the new urban agenda. If this is an outcome of HABITAT III, it will not only benefit urban planning and policymaking, but also help to bring the urban agenda in line with conservation and with the Post-2015 Development Agenda.

Increased authority, capacity and resources for cities

Habitat III would be a success if it catalyzes the adoption of policies and incentives allowing city and local governments to play their critical role in implementing the New Urban Agenda, in partnership with national governments. Translating the impressive New Urban Agenda document to action on the ground requires enabling cities around the world to meet their citizens’ needs for core urban services and infrastructure. This is particularly true for rapidly urbanizing regions of Asia and Africa.

I want the Habitat III process to increase the authority, capacity, and resources for cities to become more effective partners in the development agenda.

We know that by 2050, about 3/4 of the world’s urban population will live in Asia and Africa, and 90 percent of the increase in urban population between now and then will occur in these regions. These are the regions with the largest number of low-income countries, fewest resources available to cities, fastest growing urban populations, and serious governance challenges. It is crucial to get ahead of the curve and give cities in these regions greater authority, capacity, and resources, within the larger framework of a national urbanization policy.

Ensuring this outcome requires a focus on at least three key areas:

  • a national policy for urban development linked to key economic and environmental goals, aligned with the New Urban Agenda and the Sustainable Development Goals (or SDGs)
  • access to multiple financing sources for cities and authorities to raise municipal finance in innovative ways
  • increased capacity for cities to manage land and provide core services and infrastructure to all citizens

Experts tend to agree that the New Urban Agenda is a comprehensive document that identifies important areas, such as the need to manage urban expansion and consider transit-oriented development—ideas included for the first time in an internationally negotiated document. But, knowing that this Agenda is not binding on countries, certain steps are important to ensure its implementation.

National policies guiding urban development enable coordination and management of the urbanization process and exist in countries such as South Korea, Brazil, and Mexico. For lower-income, rapidly urbanizing countries in particular, a national policy framework aligned with the New Urban Agenda could not only enable implementation of the Agenda, but also the SDGs at the local level. It would allow countries to harness the urbanization process to achieve broader and more inclusive development goals.

Cities need greater authority to access national and international streams of finance, as well as to raise their own revenue in innovative ways. In 2012, more than 482 million urban residents lacked access to modern fuels and 131 million lacked access to electricity; and in 2015, 140 million urban residents did not have reliable, clean water. Significant investment is needed to address the serious gap in urban services, particularly in fast growing, low-income cities. In other work we are doing, we show how effective management of land use and equitable access to core services such as housing, transportation, energy, water, and sanitation, can bring environmental and economic benefits to all city residents.

Finally, cities need increased capacity to plan and manage urban growth in the form of stronger institutions and technical expertise. As the numbers above show, large numbers of people in cities that are seeing rapid urban population growth are underserved by core services and infrastructure. In our research, we find that the lack of access to core urban services causes city residents to fend for themselves in inefficient and costly ways, with risks to the environment as well. This undermines urban and national sustainability goals. But in many countries, city leaders and municipal agencies lack the capacity to deal with this growing challenge.

I want the Habitat III process to instigate national governments around the world to adopt policies that increase the authority, capacity, and resources for cities to become more effective partners in the development agenda. If this outcome is achieved, we will start to see faster progress towards other important global agreements, such as the SDGs and the Paris Climate Agreement.

Cities and inequities

Cities are core drivers of inequities and inequalities. Habitat III has a chance to raise this issue, creating an alliance to fight inequalities by bringing together like-minded leaders from the North and South, local and national tiers, governmental and non-governmental organizations. Leaders have the opportunity to change the game of inequality by addressing the core of it—that is, the patterns of unsustainable urbanization in the North and, more recently, in the South.

Habitat III offers a chance to show the importance of sustainable urbanization to fight inequalities within and beyond cities.

Making changes will require a different view of the role of cities and their primary long-term development objectives, shifting urban development from being based on consumption and concrete buildings to quality of life, resource conservation, and sufficiency.

There is so much said about urbanization and its economic and social achievements. “This is the century of cities”, “Cities are the drivers of the economy”, “Cities are the hubs of innovations”, and so on. However, one of the less explored aspects of rapid urbanization is its relation to rising inequalities around the world.

Although growing inequalities have gained interest in global and domestic agendas, less is said about the role of urbanization in the increase of these inequalities. This pattern not only includes inequalities within cities, which are already well studied (from the favelas of Rio and Nairobi to the American inner cities and the banlieues of Paris), but other, more subtle kinds of inequalities that have both short and long-term consequences, such as energy use, carbon emissions, and migration.

Urbanization has strong links with several kinds of inequalities and inequities. The core of this problem is the capacity of cities to concentrate and consume extraordinarily, and to expel their unwanted residues to other places, causing several consequences for some of the urban population and for populations elsewhere, particularly in rural areas.

Let me give some examples. Cities concentrate human capital. They attract youth and talent to generate economic activities, leaving rural areas relegated to the elder and less productive segments of society. Take the examples of rural areas in Japan and Spain, which are deserted of young people or are completely abandoned, generating a series of social (e.g., lack of social services), economic (e.g., drop in income) and environmental problems (e.g., uncontroilled wildfires). We witness similar phenomena in developing countries, such as China and India, where the best, brightest, and fittest go to the cities.

Another example is consumption. Cities consume the bulk of the world’s energy, water, and other natural resources, directly and indirectly; some estimate that 75 percent of energy is consumed in cities. Thus, as many countries do not have the capacity and resources to generate electricity for all their population, rural areas end up short of electricity. Electrification in many countries in Sub-Saharan Africa, for instance, is less than 15 percent. Those populations are stripped of many services and economic opportunities available in cities, creating and perpetuating inequity. A similar problem happens with access to clean water, as many rural areas lack a clean water supply.

In a third example, cities in urbanizing middle-income countries tend to emit carbon per capita similarly to cities in richer countries, while some of their rural population has low or even negative per capita carbon emissions. This has implications for designing a fair global regime for ending energy poverty, tackling climate change, and achieving the Sustainable Development Goals. Urban-rural inequalities and inequities in the making of emissions of greenhouse gases and the impacts of climate change.

Habitat III could open up discussions on the broader implications of cities for increasing inequalities and inequities. Just emphasizing cities as engines of economic growth creates stiffer competition among cities, which leads to more consumption, higher concentration of wealth, and more pollution. These, in turn, increase inequities, which are generally felt hardest by the poorest and weakest in cities and rural areas, who have little voice and suffer from having fewer resources and opportunities.

Habitat III offers a chance to show the importance of sustainable urbanization to fight inequalities within and beyond cities. Pointing to unsustainable urbanization as the major source of inequalities will have long-term connotations for the people and for the planet. Following the advice of Mahatma Gandhi, the planet “has enough for everyone’s needs but not for everyone’s greed”; and cities are at the core of this debate.

The Right to the City as the center of the New Urban Agenda

The current urban development model has failed to give the majority of the inhabitants of cities a dignified urban life. This model has promoted the commodification of the city that favors financial groups and investors to the detriment of the interests and needs of the majority of the urban population. The pattern of effects from urbanization, such as gentrification, privatization of public spaces and services, basic urban segregation, the precariousness of the neighborhoods of the poor, the increase of informal settlements, the use of public investments to promote projects and infrastructure that only meet business or economic interests, indicate that new ways of life and development in cities need to be adopted in the New Urban Agenda. For this reason, the New Urban Agenda must embrace a change in the predominant urban pattern that increases urban equity, social inclusion, and political participation, and provides a decent life for the urban population.

The most important outcome of Habitat III is the emergence of the Right to the City at the center of the New Urban Agenda.

The New Urban Agenda should recognize that current urban development patterns are based on the premise of attracting business and commodification of land and the speculation that results from it will not be able to create a model of sustainable social inclusion, citizenship, democracy, cultural diversity, and high quality of life in our cities. This agenda needs a diferent paradigm to establish the link between social inclusion, participatory democracy, and human rights to make the cities inclusive, fair, democratic, and sustainable.

The New Urban Agenda, as an agenda of the United Nations that was created for the promotion of human rights and peace between nations and countries, must have as its starting point the promotion of these rights for the establishment of a new paradigm for urban development. The “Right to the City” is a new paradigm that provides an alternative structure rethinking cities and urbanization; it is based on the principles of social justice, equity, the effective implementation of all human rights, the responsibility to nature and future generations, and local democracy. As part of the New Urban Agenda, the Right to the City consists of principles, actions, targets, indicators and ways of monitoring for the modeling of inclusive, fair, democratic, and sustainable cities.

The reference documents for understanding the Right to the City as an emerging human right within the New Urban Agenda are: World Charter on the Right to the City (2004); European Charter for the Safeguarding of Human Rights in the City (Saint-Denis, 2000); Global-Charter Agenda for Human Rights in the City (Cities and Local Governments, UCLG, 2009); Right to the City Charter to the City (Mexico, 2010); Letter from Rio de Janeiro on the Right to the City (World Urban Forum, 2010); For a World of Inclusive Cities (UCLG Committee on Social Inclusion, Participatory Democracy and Human Rights, 2013); Towards a Global Alliance of Human Rights Cities for All, Gwangju, Republic of Korea (2015).

In national legal systems, references to the Right to the City occur in the Brazilian legislation Statute of the City (2001) and the Constitution of Ecuador, which contains a legal Right to the City. In Article 2, items I and II of the Brazilian city statute, the right to sustainable cities is understood both as the right to urban land, housing, environmental sanitation, urban infrastructure, transport and public services, work and leisure for current and future generations; and as democratic management through participation of the population and associations representative of the various segments of the community in the formulation, implementation, and development of urban monitoring projects, plans, and programs.

This definition brings understanding of the Right to the City as a diffuse right of present and future generations—the same concept of the right to an environment that must be preserved for present and future generations.

In Article 31 of the Ecuadorian Constitution, the Right to the City is the right to the full enjoyment of city and public spaces, under the principles of sustainability, social justice, respect for different urban cultures, and balance between urban and rural. The Right to the City is based on the democratic, social, and environmental function of property and the city, and the full exercise of citizenship.

The definition of the Right to the City adopted in the New Urban Agenda is based on Article 4, paragraph 4, of the Convention on the Protection and Promotion of the Diversity of Cultural Expressions of 2005, which includes the goods to be protected; this includes the city, which can be protected as a common good. Article 11 of the Convention Concerning the Protection of the World Cultural and Natural Heritage was an inventory of the assets that make up the world’s cultural and natural heritage. Examples of cities already included in this list are: the City of Potosi, Bolivia (2014); the Old City of Jerusalem and its Walls (1982); the Old City of Damascus, the Syrian Arab Republic (2013); the Commercial Maritime City, Liverpool, United Kingdom, Great Britain and Northern Ireland (2012); Zabīd, Yemen (2000); and the Old City of Sana’a, Yemen (2015).

According to Articles 2-11 of the Convention for the Safeguarding of the Intangible Cultural Heritage, materials is also allowed to expand the protection of areas regarded as sites of intangible cultural heritage to consider urban and rural areas. Examples of urban and rural areas that are in a representative list of intangible cultural heritage sites include: the cultural space, Yaaral degal and Mali (2008); the Palenque cultural area of San Basilio, Colombia (2008); Fiesta of the Patios in Cordoba, Spain (2012); and Majlis, cultural and social spaces in the United Arab Emirates, Saudi Arabia, Oman, and Qatar (2015).

The Right to the City is therefore an existing collective of rights, such as the right of the inhabitants of present and future generations to occupy, use, and produce fair, inclusive, and sustainable cities as a common good, through a broad interpretation of cities and cultural property in accordance with international conventions mentioned above.

The Right to the City is applicable to all cities and human settlements within national legal systems. Based on this definition above, the Right to the City is a collective / diffuse right to see the city as a collective space that belongs to all of its inhabitants; the Right contains three essential elements: legal protection of cities as “commons”; collective / diffuse law; and collective ownership exercised by representative groups of residents, residents’ associations, non-governmental organizations, and public defenders and the public ministry, for example.

The Right to the City must be adopted and understood in the New Urban Agenda as the right of all inhabitants of present and future generations to occupy, use, and produce cities that are fair, inclusive, and sustainable. The Right to the City also implies that governments and people have a responsibility to claim, defend, and promote this right to the city as a common good, which contains the following components: a freedom from any form of discrimination; inclusive citizenship; political participation; fulfillment of social functions; quality public spaces; gender equality; cultural diversity; inclusive economies; and a common ecosystem that respects the rural-urban linkages. The Right to the City as a collective / diffuse right can be exercised in each metropolis, village or town that is institutionally organized as a district local administrative unit or municipality, or an area that is metropolitan in character. It includes the urban space and its rural or semi-rural surroundings.

Coupled with the adoption and these definitions of the Right to the City, the New Urban Agenda should contain tools for monitoring the implementation of this right by countries such as:

  • the establishment by the UN of a task force that, beginning in 2017, will campaign, sensitize and mobilize regions and countries for the implementation of the New Urban Agenda;
  • the creation of an international observatory for the Right to the City as a mechanism with which to gather information (i.e., best practices, legal frameworks, case studies) and to promote the Right to the City in an international forum
  • the gathering of all relevant stakeholders to push the agenda of the Right to the City (including global organizations, all levels of government, civil society, and the private sectorsocially responsible);
  • the production of regular reports on the state of the New Urban Agenda at national and regional levels every three year.

Time to address inequality

A clear and concerted focus on reducing inequalities within cities would be the most important outcome of Habitat III. Over the past twenty years we, the global community, have turned our attention to addressing challenges of poverty, environmental degradation, and resource consumption. What we seem to have largely neglected is the growing social and economic inequalities within our cities and societies. Habitat III, with its vision of promoting inclusive cities, is the perfect opportunity to thrust this issue into the spotlight.

Habitat III could forge the way towards a more meaningful understanding of and action against inequality at the individual city and settlement scale.

While we have not completely addressed the challenges of poverty or climate change yet, our performance is moving in the right direction on these fronts. Last year saw the number of people living in extreme poverty fall to below ten percent (still too high of course), and the decoupling of global energy-related carbon dioxide emissions from growth. Unfortunately, the same cannot be said of inequality. Far from tackling it, we are still figuring out how to best measure and monitor it. In the G20 summit last month, there was a call to pay greater attention to global inequality, a metric we have only recently been able to calculate. Habitat III could forge the way towards a more meaningful understanding of and action against inequality and its impacts at the other extreme: at the individual city and settlement scale.

As a built environment professional working for a large multinational company, I have recently come to realise how little our industry understands the issues related to inequality. This is despite our work often having a direct and sometimes profound impact on these issues. Whether it is new master plans, cultural facilities, or transport corridors, such projects can either improve or worsen inequality in a society through the opportunities provided for access to employment, amenities, or housing, for example. Yet, project teams are rarely aware of such implications.

What will it take to get to a point where local economic and social inequality is adequately addressed? First, we will need an open and honest discussion on the state of inequality in our cities and its impacts. This will likely mean investigating ways of measuring and reporting inequality such that it becomes relevant and meaningful to multiple audiences: policymakers, developers, residents…etc. The discussion will also need to include a deeper understanding of the global and local policies and paradigms which have led to the current situation.

Academics and professionals who are already convinced of the need for action will have to articulate their arguments in the form of plausible solutions and strategies. These will vary from city to city, even from neighbourhood to neighbourhood, depending on the type and extent of inequality. Solutions will likely include measures at various levels, from global trade agreements and national economic policies to local plans and development controls. If we have learnt anything from the climate change movement, it is that we cannot afford to wait until a majority is convinced of the scale and importance of the challenge in order to begin addressing it. In addition, people respond far better to solutions than to alarms.

Going back to built environment professionals, we will need to train these professionals to understand and address inequality challenges. Consider that 10 years ago, only a minority of professionals understood sustainability appraisals, and it was perfectly acceptable to have a portfolio of one or two token “sustainable projects” in a portfolio of hundreds of “business-as-usual” projects. There was still much discussion about how to define and measure “sustainability” and how to convince authorities, clients, and stakeholders of its value. I may be overly optimistic, but I think that we are in a different place now: one where environmental sustainability is often the starting point and not the long-term aspiration. The same could and should happen for inequality.

Habitat III could be the beginning of a paradigm shift that will mean, 10 years from now, we are able to better understand and address inequality in our cities. A new generation of built environment professionals will consider shaping an equal and inclusive world to be their responsibility, whether they are private consultants, public officials, or members of civil society. Inequality, just like extreme poverty and greenhouse emissions, will have turned a corner and begun its decline.

Aside from the organizational deficiencies of the Habitat III Secretariat, which have left many organisations, including strategic partners of UN-HABITAT, scrabbling around at the last minute to find alternative venues and formats for planned side and networking events in a way that might make navigating the site and programme difficult, this summit has profound symbolic importance. This significance lies in the unprecedented global attention to and recognition of the key role of urban areas and other sub-national entities in the meeting, the challenges of climate/environmental change, and promoting transitions to sustainable development.

The most important outcome from Habitat III would be a commitment to the rapid establishment of clear and specific implementation and verification mechanisms for the New Urban Agenda.

The New Urban Agenda (or NUA), to be adopted by world leaders as the centerpiece of the summit, has been forged through long and wide-ranging participatory processes involving government negotiators and diverse stakeholder groups around the world. The extent of engagement by such non-state actors in UN parlance, first experienced in the formulation of the 17 Sustainable Development Goals (or SDGs) adopted by the UN General Assembly last year, is itself evidence of belated and essential recognition that national governments can no longer address today’s societal challenges alone.

Not only does the NUA provide a progressive and holistic approach to sustainable urban development, it also formally recognizes the essential role of sub-national entities (i.e., urban local and regional authorities) in promoting such urban sustainability transitions. Curiously, despite such bodies constituting fundamental parts of the state sector, the UN still defines them as non-state entities. Accordingly, formal recognition in the NUA required a protracted struggle against opposition from various national government negotiators seeking to preserve an outdated central government monopoly of power in the UN system.

The NUA also recognises the importance of engaging all stakeholder groups, including academia, and urges the formation of multi-stakeholder partnerships to promote urban sustainability. It stops short, however, of providing any specific mechanism to establish a science-policy interface through which to mobilise research and scientific evidence as the basis for implementing evidence-led policy. The previously proposed Multi-Stakeholder Platform—which grouped academia together with civil society—was cut from the semi-final draft during the Surabaya negotiations in July. This illustrates how forging the intergovernmental consensus required in order to agree and adopt the NUA in Quito has produced a document that will serve that purpose very well, but which lacks teeth or any monitoring and evaluation stipulations beyond very general means of implementation and four-yearly progress reports to the UN.

Similarly, attempts to establish a formal link between the NUA and the broader 2030 Agenda for Sustainable Development and the associated set of 17 SDGs could not gain the required support for inclusion. Hence, the NUA merely acknowledges these and other relevant documents such as the Sendai Framework for Disaster Risk Reduction in the Introduction, but the opportunity to use SDG 11 and the relevant elements of other goals as a monitoring and evaluation framework was lost.

Hence, to my mind, the most important outcome from Habitat III would be a commitment to the rapid establishment of clear and specific implementation and verification mechanisms. Perhaps the SDGs could still be mobilised to this end outside of the NUA itself, in order to avoid having to establish a wholly different set of metrics.

Another key aspect will be to engage the urban science research community (which is diverse and by no means restricted to universities and higher education institutions) and other important holders of local urban knowledge (including indigenous knowledges). These could be constituted (sub-)regionally, on the basis of agro-ecological or physiographic zone, or nationally to promote the availability of appropriate evidence alongside the strengthening of multiscalar governance between urban, regional, and national government bodies within each country. Such engagement processes should be as lean and bureaucracy-light as possible.

That all these issues remain to be addressed outside of the NUA itself will add to the overall administrative and negotiation burden after the conference, and incur delays, as will the commitment to commissioning an independent external review of UN-Habitat contained in the final NUA text. While perhaps politically expedient, this invokes several large hostages to fortune and risks the loss of momentum so carefully built up through the SDG and NUA negotiation processes. To lose this historical urban moment would be a tragedy, particularly after the vast energy expended to date in pursuit of greater urban sustainability.

The UN’s Habitat III conference is fast approaching. As a person working in the international NGO community, I think the most important possible outcome of this great event would be the strengthening of international exchange and cooperation on human settlement development over the next few years.

To achieve sustainable urbanization post-Habitat III, national governments should build capacity, mechanisms, and platforms.

The reasons that this outcome is most important to me are twofold. First, the need to jointly fight against climate change. The threat of climate change to the entire human community and the human settlement has reached universal consensus. No country can stay safe alone, or be spared by climate change. We need to join hands and work together to meet this challenge by strengthening cooperation in the fields of technology, information, capital, talent, and so on. The goal of controlling global temperature rise won’t be possible without this joint effort. Second, we need healthy development of urbanization. Urbanization has become an important engine for promoting world economic development. Urbanization is also one of the key themes of the “New Urban Agenda”, which is a programmatic document of Habitat III. The next 20 years is going to be a critical period of urbanization, especially for developing countries. We are in urgent need of experiences and lessons from other countries to use as references, via international exchange and cooperation.

In order to achieve this outcome, it is important for country governments to try to achieve the following points:

1) Capacity building. Provide training for policy makers and relevant stakeholders, so that they realize the importance of international cooperation, have the necessary knowledge of it to be able to practice it, and, ultimately, to be good at implementing it. For example, the National Academy for Mayors of China undertakes the task of training the nation’s Mayors. An important part of the training is to teach the Mayors how to conduct international exchange and cooperation between cities

2) Mechanism building. Establish a fair, mutually beneficial, and win-win international cooperation mechanism that is constructed, shared, and co-ruled by countries of the world. For example, the New Urban Agenda issued by the United Nations is actually a new international cooperation mechanism of this kind

3) Platform building. Create broad international cooperation platforms among country governments, non-governmental organizations, and other relevant stakeholders. The Asian Infrastructure Investment Bank, initiated by China and participated in by various country governments, is one example of an international platform working to promote infrastructure construction that can benefit the development of human settlement.

Habitat III and the Right to the City—a commitment to a paradigm change?

After almost three years, including the last four months of intense and not always easy negotiations, the text of the so-called New Urban Agenda (or NUA) is finally ready for approval during the UN’s third Conference on Housing and Sustainable Urban Development in Quito, Ecuador (Habitat III). Some voices are quite satisfied with both the process and the outcome so far, while others are not. Some voices are optimistic about the implementation and follow-up measures that have been established; others are not. What is certainly clear is that the general balance cannot be framed in a categorical, “all or nothing” formulation.

The inclusion of the right to the city framework in the New Urban Agenda is the most important outcome of Habitat III.

Thorough the process, several civil society organizations, including Habitat International Coalition (or HIC) and the Global Platform for the Right to the City (or GPR2C), in partnership with international networks of local governments, have participated at several of the preparatory steps, such as the regional and thematic official meetings, multiple editions of the Urban Thinkers Campuses and the General Assembly of Partners. At the same time, our members were engaged in the Policy Units responsible for drafting the substantive inputs for the New Urban Agenda’s first draft (May 2016), and we collectively reviewed and provided feedback on many of the subsequent versions as well as the Issue Papers released since May 2015.

As an international network which has the privilege, but also the huge respon­sibility, to have actively participated in the two previous conferences (Habitat I in Vancouver, 1976, and Habitat II in Istanbul, 1996), HIC maintained a positive yet critical voice, making public its concerns and proposals since the beginning of the process, which have been united around three large axes: a) the call for an holistic and integrated territorial approach to human settlements, evaluating the implementation of the commit­ments assumed by different actors as part of the Habitat Agenda (1996); b) the responsibility to mainstreaming human rights in public policy, according to international law, and taking into account the achievements—but also the growing challenges—during the last 20 years; and, c) the strong demand for a wide and substantial participation of non-State actors in the debates and decision-making processes, giving particular relevance to the communities, organizations, and individuals traditionally marginalized and excluded.

In that context, as part of the GPR2C, we strongly campaigned for over a year for the explicit inclusion of the right to the city as the cornerstone of the NUA. Thanks to international mobilization and tireless advocacy activities at multiple levels, the definition of the right to the city and many of its main principles and contents are now part of the “shared vision” in the Quito Declaration (paragraphs 11-13) to which the world leaders will be subscribing, making this the first time that this concept is included in an international agenda signed by the national governments at the UN level.

The synthetic definition refers to the “equal use and enjoyment of cities and human settlements, seeking to promote inclusivity and ensure that all inhabitants, of present and future generations, without discrimination of any kind, are able to inhabit and produce just, safe, healthy, accessible, affordable, resilient and sustainable cities and human settlements, to foster prosperity and quality of life for all”. The authors of the document also recognize “the efforts of some national and local governments to enshrine this vision, referred to as right to the city, in their legislations, political declarations and charters”.

Among the key components, it is worth mentioning:

  • The respect and guarantee of all human rights and gender equality for all;
  • The social function of land, the public control of gentrification and speculation processes, and the capture and distribution of land value increments generated by urban development;
  • The promotion and support of a broad range of housing options and security of tenure arrangements, including the social production of habitat and rental, collective, and cooperative models;
  • The prevention of forced evictions and displacements, as well as tackling homelessness;
  • The recognition of the contributions from the informal sector and the social and solidarity economy to the urban economy as a whole;
  • The commitment to sustainable and responsible management of natural, heritage, and cultural goods; and,
  • The integrated vision of the territory beyond the urban-rural divide, understanding regional interactions and responsibilities beyond administrative boundaries.

Although all the references to “democracy” have been removed from the text after the first draft (we want them back!), there are several mentions of the promotion of substantial citizens’ and social participation in the design, implementation, monitoring, and evaluation of public policies and national and local budgets. The document also mentions the need for greater inter-institutional coordination inside and between the differ­ent government sectors, as well as the recognition of the key role of subnational and local governments in advancing towards more inclusive, participatory, and sustainable cities.

We are not naïve and we know that having those values and commitments on paper will not be enough. We also know that many of those same values and commitments were already enshrined in the Habitat Agenda (1996) and even before, as part of the Vancouver Declaration (1976).

A real change of paradigm will necessarily include a serious questioning of the current production, distribution, and consumption patterns; of goods and services in general; and of human settlements in particular. The mantra of “sustained economic growth”, repeatedly mentioned in the NUA is clearly not compatible with social justice and the planetary boundaries. Maybe a concrete example will help to illustrate this principle: the policies of building and selling houses do not necessarily comply with the right to adequate housing; on the contrary, as the 2008 financial crisis showed, patterns related to the housing market can result in a massive social, economic, and environmental disaster.

The growing inequality, tensions, and conflicts in all regions of the world—with their spatial manifestation in terms of territorial segregation—feed the exclusion and poverty circle, as well as the limitations and vulnerability of the limited representative democratic systems current in place; these are clear wake-up calls that cannot be ignored any longer.

We believe that the right to the city, as a political and programmatic agenda, offers concrete instruments to reshape human settlements as common goods and collective creations. Moving towards the implementation of this paradigm of cities and territories as rights, and not as commodities, will require fundamental changes in the conceptions, knowledge, attitudes and practices of a wide range of actors and institutions at multiple levels. Are you ready to be part of that?

Half-Earth Cities

Many voices. Greener cities. Better cities.
If everyone on Earth lived like the average Melburnian or San Franciscan, we’d need the equivalent of nearly 8 planets. Seven of those planets don’t exist.
In Half-Earth: Our Planet’s Fight for Life, published in 2016, E. O. Wilson made a reasoned and impassioned call for making our human future fit within the boundaries of just half a planet, with the other half given over to human-free nature. He reasoned that unless natural systems have sufficient wildness and integrity to function and evolve without human interference then it was entirely conceivable that the biosphere would be damaged beyond repair, and that its ability to support human societies would cease.

E. O. Wilson is a leading light amongst a coterie of scientists and conservationists “who have argued for years that setting aside at least half of the world’s land mass as off-limits to human enterprise is necessary if we are to conserve our planet’s biodiversity.”  Wilson doesn’t seem to envisage fencing things off with a Berlin or Trump wall, and argues “that the process of setting aside half the Earth doesn’t mean moving people out, but being creative with park designations, restoration, and encouraging private-public partnerships.”

Drawing by Paul Downton

In this essay, I’m not going to reiterate all of Wilson’s arguments (his book is a good read and I exhort you to get hold of a copy), but I am going to accept his conclusion that in the interest of simple survival we can’t afford to use more than half the planet for human purposes. Just half.

From a nature of cities perspective, or at least from the point of view of non-human nature, the Half-Earth concept paints a rather wonderful picture of unspoiled wilderness and rampant, healthy, biodiversity. For those of us inclined that way, the biophilic quotient of the idea is staggeringly high. Assuming that such a goal was ultimately possible, and even before we look at how it might be possible, it is reasonable to ask what sort of cities could possibly fit such a vision. Although they are epicentres of human civilisation and culture and perpetrators of just about every environmental crime on the planet, Wilson doesn’t have anything to say directly about cities or urban systems in his book, so this essay is by way of a tentative exploration of the role of cities in achieving Half-Earth.

Unequal feet

The world’s urban areas take up only 3% of the Earth’s land surface—about 1.5 billion hectares—and half the world’s population lives in one third of that total urban area (see here). So if half the world’s population can live on just 1% of its land surface, what’s the problem?

The problem is that cities have two footprints, created by very unequal feet. The cities may only occupy 3% of the planet’s total land area but they have evolved and grown in areas of ecological productivity and occupy 12.5 percent of that area where they consume 75 percent of resources and produce 75 percent of all waste. One of the footprints is made by buildings and infrastructure that can be fairly easily measured in simple “plan view” (the 12.5% of ecologically productive area), and the other is the ecological footprint that Rees first described in 1992, expanded on and expounded in the pioneering book, Our Ecological Footprint: Reducing Human Impact on the Earth, which he co-authored with Wackernagel in 1996. “Ecological Footprints estimate the productive ecosystem area required, on a continuous basis, by any specified population to produce the renewable resources it consumes and to assimilate its (mostly carbon) wastes” (Moore & Rees 2013), and a city’s ecological footprint can be hundreds of times the size of a city’s physical footprint in plan. The area of London, for instance, is 157,200 hectares but its total ecological footprint is some 250 times greater at 39,500,000 gha (global hectares), an area larger than all the British Isles (31,515,900 hectares)(see here).

Biologically bound

Despite all of our pretenses and fantasies, we have always been and will remain a biological species tied to this particular biological world.
Half-Earth: Our Planet’s Fight for Life, p. 211

That cities should be understood as not simply a collection of buildings and infrastructure but as an interdependent part of a larger regional entity is an idea that stretches back to the Ancient Greek concept of the “polis” and was fundamental to the thinking of Patrick Geddes, “founding father of town planning and environmentalism” (Kitchen 1975). Geddes inspired the work of that incomparable writer about cities, Lewis Mumford, who joined Geddes in his advocacy for a view of cities as entities intimately connected with the biological processes of their surrounding environs. Geddes “…recognized the important role of cities in the evolution of culture and maintained that a city has to be understood and integrated in the context of its biological and geographical region” (here).

A century after Geddes’ work this way of thinking about cities has yet to fully enter the mainstream, although change is afoot. Ultimately, the hinterland of cities needs to be regarded as part of their cities’ responsibility as de facto planetary resource managers. The framing of our thinking about cities has to see them in the larger context of city-regions or region-cities but as the Ecological Footprint model makes clear, the hinterland of a city can no longer be regarded as a garland of biology and resources that somehow fits neatly around its built form, but is instead more like globally distributed patches of resources, materials, water and energy connected to the city’s more familar physical form by both obvious and tenuous tentacles of road, rail, flightpaths and electronic communication.

Roads and buildings

There are approximately 200,000,000 hectares of road surface (paved and unpaved) on the planet. The problem with roads isn’t just the area covered by their surface, but their facilitation of intrusion into ecosystems. Driving 100 kms of 10 metre wide road through a rainforest doesn’t just result in damage from clearing vegetation for the roadway, its impacts are far wider, and the collateral damage from edge effects can spread into the adjacent environment much further than the width of the roadway. Road building and associated clearance in the Amazon provides a classic example.

Every building changes the condition of the place in which it is situated. Buildings modify the climate at a very local level. It’s the reason we build in the first place. Although there are innumerable buildings that don’t work very well or even exacerbate local conditions, buildings are fundamentally about creating shelter. This is why we manipulate material and resources to provide protection from the rain, channel cooling breezes, make shade, trap the warmth of the sun, and keep out the cold or the heat. The built environment can be configured to contain nature too. There are buildings that can produce conditions favourable to non-humans (albeit for human purposes) like the dovecotes that provide a home for pigeons and greenhouses that enable tomato plants to grow in cold weather. The use of glasshouses to create favourable conditions for certain kinds of vegetation and (to a lesser extent) fauna, has a history as long as that of the glass industry and 27 years ago found a kind of apogee in the shape of Biosphere 2, which was conceived as a prototype for constructing an entirely closed complex environment—an ecosystem in a very big bottle.

Advances in materials and technologies have continued to extend the scope of the humble greenhouse to embrace the concept of what might be called “pocket biospheres” across the globe, the most famous example of which is The Eden Project, constructed in a disused clay mining pit in Cornwall, England. The ambition behind these structures is often laudable, with lofty goals. The Eden Project is an educational charity that “connects us with each other and the living world” and proudly boasts that it houses “the largest rainforest in captivity”. It has spawned or inspired similarly ambitious projects such as The World’s Largest Oasis in Oman, where “A collaboration of engineering and architectural expertise has resulted in a botanic garden design that will become the world’s largest eco-park and serve to conserve hundreds of endangered botanic species”.

All of which is wonderful and positive and somehow encouraging, but as E.O. Wilson says:

The surviving wildlands of the world are not art museums. They are not gardens to be arranged and tended for our delectation. They are not recreation centers or reservoirs of natural resources or sanatoriums or undeveloped sites of business opportunities—of any kind.

He reminds us that the wildlands stabilize the global environment which supports our existence and that “We are their stewards, not their owners”.

Terraforming, and the trajectory of evolution

Let’s not be shy about this. We are unabashed planet-shapers—terraformers—and what we do affects the trajectory of evolution but, as Wilson puts it: “There is greatness in understanding the basic elements of human evolution and wisely acting upon the way they are linked”. In Half-Earth he writes optimistically that: “the biosphere gave rise to the human mind, the evolved mind gave rise to culture, and culture will find the way to save the biosphere”(p.50).

This echoes Vladimir Vernadsky’s proposition that “Just as the emergence of life fundamentally transformed the geosphere, the emergence of human cognition fundamentally transforms the biosphere”. This third phase of the Earth’s development (the other two being its geosphere and biosphere) he called the “noosphere”: the sphere of human thought. An atheist, Vernadsky shared the earliest use of the term noosphere with the radical Roman Catholic priest Tailhard de Chardin, who popularised the concept of the noosphere but related it to theology and his conviction that evolution was leading through complexity and consciousness to an ultimate “Omega Point”.

De Chardin’s ideas exerted a powerful influence on architect Paolo Soleri who interpreted complexity as key to the making of “arcologies”extraordinarily compact cities intended to maximise the growth of human consciousness and cultural endeavour whilst minimising the physical impact of the cities on the biosphere. His arcology designs provided the first detailed propositions for a kind of extreme urban solution that has had a formative influence on the development of the ecocity idea, particularly in its insistence on compact built form, the exclusion of motor vehicles and trenchant criticisms of suburbanism. Contained within their clearly defined physical boundaries, Soleri’s arcologies were designed to have (at least notionally) a minimal impact on wild nature and were conceived of as being instrumental in advancing human evolution towards the Omega Point. The idea that cities and evolutionary processes have some connection has a history dating back over a century when one of the finest and most influential sages in the realm of urban theory, Patrick Geddes, published his seminal work on Cities in Evolution in 1915.

Ecocities

Although ecocities have entered the lexicon and their influence on core ideas about what is loosely called ‘sustainable’ urbanism is undeniable, ecocity pioneer Richard Register (who became an advocate for what he came to call ecocities after being strongly influenced by Soleri) points out that their role as evolutionary agents has been almost completely neglected, that it rarely, if ever, surfaces in discussions about ecocity ideas and that evolutionary ideas are essentially absent from mainstream urban systems discourse (personal communication).

Evolution, it should be remembered, is not necessarily about upward and forward movement or progressive change. We can diminish ourselves and our world as readily as we might enhance it. It is potentially of great importance to understand that the making of cities is integral to whatever evolutionary process it is that humans are part of. The idea of Half-Earth is about understanding that humans have the power to influence the course of evolution and to make or break the ecological integrity of the planet in its presently evolved state. Failure to act on that understanding is to betray our species and diminish the potential for our collective future. The role of cities in evolution has to be embraced as a core concern in any proposal for achieving Half-Earth.

Reality and inhuman ethics

The reality of the world’s cities is so far removed from what the Half-Earth vision demands that it may simply seem preposterous to suggest that they could ever be changed sufficiently to fit on half a planet, but the picture of reality described by that vision demands that the operational values of human society and the cities that reflect those values simply must change if we are to have any hope of survival as a civilised species.

We now have some remarkable tools that might help us achieve the goal of Half-Earth Cities, including some that promise to do our thinking for us—but there are dangers in believing that we can’t solve our planet’s problems without relying on powerful advanced technology. Imagine, for instance, that we might create artificial intelligence that is charged with the task of protecting the biosphere from further degradation and returning it to ecological health. Given all the available information and a few basic algorithms to do with energy, resources, food, water and population, it wouldn’t take long for the AI to conclude that the planet would be better off without us. So if we want to stay a few steps ahead of our own cleverness, we need to work towards a healthy half planet that can support civilisation without relying on the technologies developed for the wealthy few (which depend upon a largely exploitative use of collective social and intellectual skills) but with the spirit and courage of the wise, and the wisdom that has also evolved, and continues to evolve from social exchange and shared experience.

Ecological footprint of the world’s cities

Drawing by Paul Downton

If everyone on Earth lived like the average Melburnian or San Franciscan we’d need the equivalent of nearly 8 planets just to maintain that level of consumption. Seven of those planets don’t exist. This slightly terrifying statistic is relatively well understood in the sustainable design community where the idea of One Planet Living (OPL)has significant traction. What is less well understood is that even though a full and genuine shift to OPL would be a radical and disruptive departure from business-as-usual, it would be nowhere near enough of a departure to ensure the long-term survival of civilisation.

The metric of the ecological footprint is based on data drawn from what has actually happened. It is, as my colleague Sharon Ede says, “looking in the rear view mirror”. Ecological footprint is about areas being used for productive purposes and does this well. This gives the EF substance and makes it a defensible and credible measure of resource use and its associated impacts but the metric does not include an area for the wild. To accommodate the Half-Earth scenario, OPL based on the EF metric needs to be recast as “Half-Planet Living”. The measure moves as the EF is based on a snapshot in time. As the population increases the amount of land available per person decreases. The world’s land area is 51 billion hectares. Writing in 2013, Moore & Rees observed that “There are only 11.9 billion hectares of productive ecosystem area on the planet. If this area were distributed equally among the 7 billion people on Earth today, each person would be allocated just 1.7 global hectares (gha) per capita. (A global hectare represents a hectare of global average biological productivity.)” ( p. 41 Jennie Moore and William E. Rees, Getting to One-Planet Living; Chapter 4 in State of the World 2013 Is Sustainability Still Possible? The Worldwatch Institute)

With the population now at 7.6 billion the area reduces to less than 1.57 gha per capita. UN mid-range estimates are that the world population is likely to reach 11.2 billion by the end of the century; that would result in an EF of little more than 1 gha per capita. Sharon Ede notes that the Global Footprint Network (who crunch the EF data) “deliberately choose conservative accounting methods (like not including a requirement for ecological space for other species) so they are not inflating the figures i.e., the Footprint is a huge underestimate of the impact we are having…” (email communication 20 April 2017). An assumption that we need to allow for a population of 12 billion would seem to be a reasonable basis for serious long-term planning, so that’s essentially 1 gha per person.

But the EF metric hasn’t included the wild. The basis for long-term planning of resource distribution should reflect the wild and if we accept the work of EO Wilson et al, then that 1 gha per person must be reduced to 0.5 gha. That’s almost inconceivable, but the figures do not lie.

Within this extremely constricted framework the idea of creating cities as models of miniaturisation, complexity and density makes a lot of sense and almost the only concepts developed in the modern era that address that challenge are those generated by Soleri and those extremely few people who have followed in his footsteps. If the noosphere is a real thing and if further densification and complexification are essential to human progress, then the goal of developing Half-Earth Cities becomes both a means of survival and a way to advance the evolution of our very curious species.

One gigahectare each

How do we fit cities into this? If we work with the 1 gha per person, to keep it simple, then the entire city plus the region with which it is interdependent must be planned on the basis of that figure—half of which needs to be wild. To use a very rule-of-thumb basis, a city of 1 million can only occupy 500,000 hectares for all its needs and at the same time be responsible for ensuring the continued existence of 500,000 hectares of wild land. Now, at least, we can see our way to a conceptual model for what a Half-Earth City needs to do and how much physical space it can occupy in order to obtain all of its resources and food within planetary limits. More than their cities’ purely physical dimensions, the ecological footprints of cities have to be massively reduced to fit the productive capacity of the planet and make it possible to sustain half the world in a wild state. For instance, if Melbourne’s EF is currently around 8 gha, then for it to become a Half-Earth city it would need to cut its EF to one-sixteenth, or barely 6 percent of what it is now.

This gives us a design goal. This means we can start working on this massive challenge right now. It will take decades to achieve something as confronting and enormous as Half-Earth Living but at least we can get started. It is through our cities that we act on the world, it is there that we realise the potential to shrink our footprints and manage the protection of wilderness. And, done right, the design of our urban systems can mesh with the work of Half-Earth scientists who are already designing ways to achieve an ecological safety net for the planet.

Hammarby Sjöstad — A New Generation of Sustainable Urban Eco-Districts

Many voices. Greener cities. Better cities.

Hammarby sjöstad (Hammarby Lake City) is an urban development project directly south of Stockholm’s South Island. This is no doubt the most referenced and visited spot among Scandinavian examples of implemented eco-friendly urban developments. Hammarby is included in many publications, for example in the recent Ecological Design by Nancy Rottle (2011). There are 13 000 visitors a year from all over the world.

Stockholm. Location of Hammarby
Stockholm. Location of Hammarby

The original plan of Hammarby was to develop the former industrial area to an ecological sports arena and athlete’s village – the aspiration was to develop this area for the Olympics 2012. When the bid was won by London the plans were changed and instead the Stockholm municipality – together with a number of construction companies – decided to make this the first Ecocity district in Stockholm for the first millennium. (The other was Western Harbour in Malmö which was displayed during the National Residential Fair 2001). The district is developed around Hammarby Sjö (Lake) and when it is finished it will contain around 1 000 apartments for more than 26 000 inhabitants, with 6 m2 work space/inhabitant.

The Hammarby model

One new feature of the Ecodistrict, which has won international recognition, was to integrate several infrasystems in the planning from the very beginning: technical infrastructure, mobility and communication infrastructure, building infrastructure and to some extent green-blue infrastructure. Another strong feature is the system of interdisciplinary planning of physical flows of energy, water and waste. The Hammarby model is today mimicked around the world — e.g. in the Caofeidian Ecocity development in China and in the Swedish SWECO consultant concept Symbiocity in Brasil.

The Hammarby model includes energy conservation measures in which the goal is to reduce heat consumption by 50% and use electricity more efficiently compared to the Swedish average. The share of renewable energy was also intended to be considerably higher than the Swedish average – using bioenergy and incineration of local waste to produce both locally generated heat and co-generated electricity. Large-scale local wastewater and stormwater harvest and filtration were also implemented. Stormwater devices have high aesthetical quality, which is an important factor in the livability of the neighborhood.

One of the most famous features of the Hammarby model was the implementation of a high-tech waste sorting and waste transportation system, also linked to the local energy production in Stockholm. The most spectacular technical system is perhaps the vacuum waste suction system of various household waste functions (including, for example, burnable and compostable waste). In this system, which is implemented all over the district, filled waste bags are intermittently transported to sub-stations in the periphery of the district, which results in markedly efficient waste collection and no need for waste-lorries to enter the residential areas at all.

A more sustainable mobility and communications infrastructure

Hammarby sjöstad is the first district in half a century in which a tram-line was built as the main commuting traffic mode and the first tram-line ever which was outlined as a cross connection in the southern part of Stockholm. Other features of the sustainable local transport system include an attractive pedestrian and bicycle network, a large carpooling system, a popular ferry connecting the Hammarby sjöstad with Stockholm Downtown’s South Island.

A dense green-blue city district with basically positive aesthetic qualities

Hammarby sjöstad has been planned with a dense settlement structure with typically 4-5 story buildings in a compact neighbourhood outline, but with reasonably spacious green courtyards. The moderate height of the houses and the sufficiently spacious neighbourhoods allow for both wind-shielded and sunny inner courtyards with ample possibilities and incentives to develop both inviting entrance green and common courtyard green, and facilitating small-scale cultivation in micro-garden plots or small greenhouses. There are also established green roofs which are an important part of the stormwater system as well as providing important habitat. The area is, at a larger scale, linked to one of the green wedges – the Nacka Wedge with a large ski-slope, vast forests, small fields and several lakes.

Other district green areas of importance are the Luma-park, the Oak park and the Sjöstads parterre. In Oak Park there are quite a few very old oaks trees which have the highest historical, ecological and aesthetical values.

Hammarby sjöstad features many aesthetic qualities: the traffic planning has created a good soundscape with a low level of noise, allowing attractive sounds to enrich the residents’ living environments. The first phases of the Lake City neighbourhoods are both wind protected and offer sunny courtyard and public space areas. The local areas in Hammarby are easy to keep clean, to maintain (e.g., green and blue elements) and the whole district has an attractive background fragrance due to lack of garbage, much green structure, soil surfaces, lake and designed streams.

An evolving Sea City service structure

Slowly the commercial and municipal services are developing in Hammarby sjöstad. From the beginning it featured a number of restaurants and cafés, whereas the general stores where developed more slowly. This may have been an advantage as the expected wealthy senior population was not the dominant resident category in the Hammarby. Instead the sjöstad mainly attracted young families without or with one child. The result was an initial lack of stores for children and families, municipal services (schools and nurseries) and appropriate green areas. The sjöstads parterre is an important common open space – even if it is mainly restricted to adjacent neighbourhoods and lacks several pedestrian path qualities with cafés and shops.

Pic26BSome weak points that need to be developed

Hammarby sjöstad lacks sufficient intermediary scale (district) green areas, which makes it important do develop “leisure commuting” both to the southern green wedge across the two ecoducts built over the main South link freeway and across the Hammarby lake to the South Island. The Lake City so far also lacks proper public squares for open space markets and an intense city life. It also still lacks a core centre and smaller local cultural centres with cinema, theater and music stages as well as public indoor meeting places. The apartment prices are rather high and there is a lack of affordable rental flats. The demographic structure is biased towards young families, which will create peaks of societal needs (daycare > schools > secondary schools > unqualified jobs). Also the cultural diversity is low and the area is highly income-segregated. The whole sustainability concept is challenged as long as the Hammarby sjöstad waste-food cycle is not better developed in micro-regional and local scales. The Hammarby could also strengthen its social cohesion in order to develop its sustainable lifestyle habits. Today the Lake City offers a more sustainable framework for everyday life compare to the average Swedish city but hardly challenges its inhabitants to lead a more resilient life.

On The Nature of Cities

Hands-On Habitat Volunteers—A Key to the Future of the Environmental Movement

Many voices. Greener cities. Better cities.

The near absence of any discussion of the environment in the presidential debates has led me to think about the state of the U.S. environmental movement. In one sense, conservationists in the U.S. should be proud of all that we have accomplished in cleaning up our air and water, restoring fish and wildlife, and increasing consumer demand for environmentally sound products. On the other hand, climate change, ocean acidification, biodiversity loss and other key indicators of environmental (and economic) health are worsening, and the environmental movement has not succeeded in elevating these issues to the top of the national priority list. We in the movement simply need to wield our power more effectively if we are going to achieve needed societal change.

Much has been written on how this might be accomplished. Rather than summarize the literature, I’d like to focus on an exciting development that offers great promise for movement building: the explosion of hands-on habitat restoration and wildlife gardening being carried out in urban and suburban communities around the nation.

Redefining our base

In Fayetteville, Arkansas (USA), for example, community volunteers and local officials have committed to provide habitat for wildlife on over 250 sites, including city parks, school yards, backyards, businesses and even wastewater treatment plants. The mayor attends the dedication of every Schoolyard Habitat® and educates school kids about the importance of conserving wildlife. As a result of these volunteer-driven efforts, the National Wildlife Federation has certified Fayetteville as a Community Wildlife Habitat.

Fayetteville volunteers and officials celebrate the city’s certification as Community Wildlife Habitat.

I anticipate that many readers of this blog will wonder why I would bring up hands-on neighborhood improvement efforts in a discussion of the environmental movement. After all, the term “movement” implies collective political action, doesn’t it? A search of the 150 most recent U.S. news articles using the terms “environmental movement” and “conservation movement” reveals that this indeed has been the connotation: 91 percent used the term in a political or policy context.

I wonder whether by defining itself in political and policy terms and excluding community cleanups and other hands-on volunteer work, the movement has understated its scope and influence—and perhaps even turned people away. A March 2010 Gallup poll found that the proportion of Americans who were either active in, or sympathetic to, the environmental movement had declined from 71 percent to 61 percent between 2000 and 2010. Those who were neutral toward the movement rose from 23 to 28 percent and those unsympathetic went from 5 to 10 percent. Gallup attributed these changes in part to increased political polarization.

Historian Christopher Sellers reminds us that environmental causes were “extraordinarily popular” in the 1960s and 1970s. Inspired by Rachel Carson’s landmark book Silent Spring, environmentalists rallied suburbanites around excessive pesticides and other direct threats to their personal well-being. Sellers argues that for the environmental movement to regain widespread acceptance, it must return to its suburban roots and refocus on local concerns. According to Sellers, even climate change can be placed in a local context.

Easy steps with concrete outcomes lead to increased engagement

I mostly agree, except I think it would be naïve to believe that many of the people who are currently uninvolved with conservation issues will immediately leap into the political fray once global issues are reframed as local ones. A key lesson from the behavioral research is that education on the issues, by itself, rarely stimulates action. Many people fail to take action on the environment despite being both knowledgeable and concerned. Behavioral change typically comes about after an individual completes small first steps and sees positive and concrete outcomes.

This is one of the reasons why I am so excited about the volunteer habitat restoration and wildlife gardening projects that are now proliferating across the country. The actions are very manageable and they produce very tangible outcomes that benefit local quality of life.

One project that impresses me is the recent effort to restore a nature education facility in Atlanta led by the West Atlanta Watershed Alliance, with support from the National Wildlife Federation’s Earth Tomorrow program. The Outdoor Activity Center, sited in one of the largest urban forests in Atlanta, was falling into disrepair when WAWA and Earth Tomorrow volunteers stepped in to remove invasive plants, prepare wildlife gardens, install bird feeders and repair trails and foot bridges. The facility is now providing a site for science-oriented field trips for Atlanta public schools as well as serving as a nature oasis for the local community.

Positioning ourselves for success with wildlife and habitats

As volunteer efforts proliferate, a key challenge for local leaders and their partners in conservation organizations will be to design projects that measurably improve the condition of imperiled wildlife species and habitats. One example of how this might be accomplished comes from the Chesapeake Bay watershed, near Washington, D.C. where I live. In the Oyster Gardening Program, volunteers in Maryland and Virginia sign up with the Chesapeake Bay Foundation (CBF) to grow oysters in rivers and streams in their communities. Volunteers place seed oysters into cages and install the cages at private docks, community piers and marinas. After a year and inch or two of growth, the volunteers return the oysters to CBF, which then plants them in a sanctuary (non-harvestable) reef. As the reef grows, CBF will be able to quantify the oysters’ role in filtering the bay and restoring it to health.

A key focus for the National Wildlife Federation is finding ways to achieve similarly measurable and achievable gains for species and habitats in cities and suburbs. As is the case around the globe, metropolitan areas in the U.S. are generally located in biologically rich locations, with roughly 60 percent of the nation’s imperiled species found there. The urban and suburban residents who are willing to get their hands dirty to improve local parks, school yards and other open spaces will be key to our success in conserving imperiled wildlife.

Over time, as more citizens become engaged in stewarding their local land, water and wildlife and become better connected with conservation organizations, the clout of the environmental movement will grow. For some citizens, a degree of engagement with politics will flow from hands-on stewardship work, since politics can so easily jeopardize hard-won progress. Others may want to focus solely on achieving on-the-ground progress and will want to steer clear of politics. In fact, given the political context in which many people in the U.S. and around the globe operate, this may be the only feasible way to have an impact in the near term.

Conservation organizations should be willing to accept these volunteers and work with them on their terms. If they do, and legions of local stewards become better integrated into the broader environmental movement, the cause of conservation will greatly benefit.

Hearing from the Future of Cities

Many voices. Greener cities. Better cities.

“What I like about this landscape is that it’s not painted….I can move around into it and feel it. I think about all the things I can find there. But, after I leave this picture, something always changes, and I do too.” —Gabriela Villate, 7 years old.

“This is my drawing. I watch as the mountains come up close and then move back.” Photo: Fundación Cerros de Bogotá

People see a face in the landscape, one which is directly related to their daily lives, to their well-being and to their sense of belonging to a place. This is the idea of the landscape as a “face, or geographical form of space” (Fernandez-Rodriguez, 2007).

What happens when we “freeze” the landscape on pieces of paper? To find the answer, for the past eight years our foundation, Fundación Cerros de Bogotá, has been inviting children from Bogota and the surrounding region to paper our walls with their landscape drawings. (Bogotá is a humid tropical city located at 8,700 feet above sea level, on a highland plateau in the eastern range of the Andes.)

Last year alone, children from diverse backgrounds sent us more than 2,000 drawings of Bogotá’s mountains and their surroundings. Some of the drawings are included in this essay, but you can see many of them in the video below.

In pondering all of these children’s drawings and listening to their stories about their interests, we began to realize that these children would be our greatest allies in bringing about the changes we have been dreaming about.
Their drawings interpret the landscape from a multitude of perspectives, including the aesthetic, the spontaneous, the experiential, the critical and the residential. They reveal how the landscape plays a permanent role in forming children’s awareness of their habitat, how it lends meaning to their world while acting as a mirror of their psychological states of well-being or despair, serenity or anxiety, safety or danger, happiness or sadness. Through these drawings it is clear that the landscape possesses intangible values that influences everything from a city dweller’s sense of self-identity to their cultural expression (Zuluaga, 2015).

Why should children’s drawings be taken into account when making decisions about the city’s future?  

Children’s landscape drawings often include members of their immediate circle: teachers, parents, friends, classmates; which means that a child’s representation of the landscape can go beyond being just a simple portrait of a piece a land. It can also include “the formal representation of emotional relationships among individuals and societies…shaped by social, economic, environmental and cultural factors” (European Landscape Convention, 2000).

It is “any part of a territory perceived by the local population, the character of which is the outcome of actions and interactions produced by natural and/or human factors” (European Landscape Convention, 2000).

Over the course of many years, Fundación Cerros de Bogotá has advocated for a comprehensive plan by which to guide the development of the city’s mountain border. This plan is based upon community participation, and emphasizes biodiversity as the most important structural component in a socio-ecological pact that links neighboring communities throughout the mountainous corridor. The concept of such a socio-ecological system encompasses a comprehensive perspective of the ecosystem, including the cultural component. Therefore, when the social value of an ecosystem is measured, humankind’s perspective and participation in it must be included.

However, to date, our efforts have only slightly influenced public decision-making, due to the fact that the mountains’ cultural and environmental importance barely registers among local politicians. Such is the case, even though a November, 2013 Colombian Council of State ruling decreed “that unoccupied areas   surrounding building sites are to be given priority use as ecological public spaces to compensate the residents of Bogotá for any ecological damage that may have occurred on said building sites, thereby guaranteeing the public right to recreation.”

Because city governance is highly complex and involves a wide variety of actors, each of whom has specific political interests, and because local public policies are generally executed at a sluggish pace, the city’s mountain border, with its enormous potential to improve residents’ daily lives, remains widely overlooked.

So, in pondering all of these children’s drawings and listening to their stories about their interests, we began to realize that these children would be our greatest allies in bringing about the changes for the city we have been dreaming about.

Because Bogotá’s eastern mountain range is so vital to the city’s environmental, social, and cultural development, the Colombian Council of State, in a 2013 ruling, ordered a number of public institutions to carry out programs that would compensate the city’s inhabitants for the years of ecological damage that has been done to the city’s mountainous border.

In the frame of a proposal made by this author: “The Eastern Mountain Ecological Corridor”, also known as the “City Border Pact” (see Note below), recognizes that the city’s incomparable eastern mountain border must be protected through civic agreements that will ensure biophysical restoration and the public’s right of use and recreation within the designated Green Belt.

This Pact involves three major strategies: the social, the biophysical and the spatial, all of which are based upon regenerative planning and social inclusion. The Pact’s overall aim is to restore the area’s biodiversity while at the same time ensuring that the local community participates in territorial appropriation for the benefit of the entire region. This project was created in an effort to halt the ecological degradation and fragmentation of the city’s eastern mountain range; to this end, it has established guidelines, objectives, regulations and designs for the development of the mountain socio-ecological corridor.

We began to understand that effective change could only be brought about by forging a long-term pact with the actors and neighbors who live in and around the city´s mountain range; and that this pact that would also have to actively include the area´s children and young people both in and out of their schools.

Approximately 74 private and public schools and 13 university campuses are located along the 36-mile Bogota mountain border. Some of these educational facilities can occupy up to 150 acres of private property. On the basis of this data, it was clear that the more than 11,600 mountain school students, as well as other students from elsewhere in the city, would have to play a major role in protecting this ecological corridor.

The future of Bogota and its mountains depends upon local children becoming eco-citizens and agents of change

In order to provide greater scope to the annual exhibit of children’s drawings and narratives that fill our Foundation’s headquarters every year, we decided to set up a Bogota Mountain Schools Network. This strategy includes Bogota schools in the management of the city’s mountain range. Students are encouraged to hone their knowledge of ecological sustainability through the study of local geography and environmental resource management.

We can talk about eco-representatives: children as eco-civic citizens and managers of change in the future of the landscape and biodiversity at the region of Bogotá.

Why have we called upon students to become eco-representatives?

Children’s landscape drawings provide an unassuming means for them to express themselves. During the past eight years, as we have collected thousands of such drawings, local politicians have produced few, if any, tangible programs to protect Bogota’s Mountain Reserve. Therefore, we founded a transversal education task force, The Bogotá Mountain Schools Network, to focus on promoting eco-education as the basis for long-term nature conservation. This task force now includes, in addition to the Fundación Cerros de Bogotá, Opepa, the Gimnasio Femenino (a private campus on the mountain border), and other partners: the Bogota Botanical Garden and the Instituto Humboldt. 

The individuals who guide these institutions, with their tireless commitment in time and energy, have made it possible for us to reach a number of our goals.

The Bogotá Mountain Schools Network gives private and public school children the chance to participate in important environmental initiatives that will affect their surroundings in the future.

Our task force has invited a number of children from diverse backgrounds to attend our meetings where they are designated as “important urban naturalists”.

“My father told me that when he was a student, the school had to take everybody to visit the Sumapaz Paramo, or some other place high up in the nearby mountains”—the Sumapaz Paramo, or high mountain meadow lands, is a rural area within Bogota’s city limits; at 44,000 acres, it is the largest paramo in the world—”but, nowadays, kids don’t know very much about local geography. These drawings show how students who walk to school at the foot of the mountains see them, as well as how students who live far away are only able to see the mountains’ profile at the edge of the city.”

Getting children involved in activities and decision-making within their own surroundings contributes to their tapestry of relationships and nurtures better citizens capable of transforming the cities they live in. The jointly-sponsored process we have described recognizes children’s perceptivity of their surroundings as well as their relationships with neighbors; it aims to transform consumer habits by making them more eco-friendly; and, in the long-term, it aims to influence public policy, education and child-rearing. Moving beyond being mere representatives of an ideal or of being critics of the current situation to being active participants among residents in micro-territories will hopefully serve to unite every Bogotá neighborhood in creating a more equitable urban environment, where nature’s spirit will reside in every home.

The landscape of the future is child’s play.

Heat Risks are Rising in Cities Worldwide — Here Is How to Plan for Urban Heat Resilience

Many voices. Greener cities. Better cities.
Faced with the growing threat of extreme heat, cities everywhere need to plan for urban heat resilience — proactively mitigating and managing heat across urban systems and sectors. Here are seven key principles and eight strategies or urban heat resilience.

Cities everywhere are getting hotter. Globally, every year from 2013 to 2021 ranked among the 10 hottest on record due to climate change. Urban areas are generally warming at a faster rate than rural or natural areas due to the urban heat island (UHI), a phenomenon whereby the built environment and waste heat lead to increased temperatures.

Risks of both chronic heat and extreme heat events (e.g., heat waves) are growing and negatively impacting communities in a variety of ways. First and foremost, heat kills. In the United States, it is the number one weather-related killer. It also affects quality of life, local economies, energy and water use, ecosystems, infrastructure, and agriculture. In a recently published study, we surveyed a diverse sample of planners in cities across the United States about heat. Over 80% of planners reported experiencing some heat impact and a majority of planners were at least somewhat concerned about heat.

It is also clear that heat exposure and vulnerability are inequitable. Heat disproportionately affects marginalized communities and intersects with other systemic inequalities related to environmental quality, workplace safety, housing, energy, transportation, and healthcare.

PAS Report 600: Planning for Urban Heat Resilience cover (American Planning Association 2022)

Faced with the growing threat of extreme heat, cities everywhere need to plan for urban heat resilience – proactively mitigating and managing heat across urban systems and sectors. Yet, compared with other hazards like flooding, heat governance, or the actors, strategies, processes, and institutions that guide decision-making for mitigating and managing heat as a hazard are underdeveloped. Our research suggests that few studies have examined heat planning and governance. In most cities, it is unclear who is responsible for addressing heat. But this may be changing, as a few cities, including Phoenix, Arizona, and Miami-Dade County, Florida, have recently appointed heat officials.

In order to help elevate awareness of heat risk and inform heat planning in cities, we recently published a new Planning Advisory Report for the American Planning Association entitled Planning for Urban Heat Resilience. This report, which is freely available to download thanks to a grant from the NOAA Extreme Heat Risk Initiative, explains the complexities of heat and outlines an actionable framework for holistically planning for heat resilience.

A framework for planning for urban heat resilience

In our framework, planning for urban heat resilience means setting clear goals and metrics of success for both heat mitigation (cooling communities with vegetation and design of the built environment) and heat management (preparing for and responding to chronic and acute heat risk that cannot be mitigated). This requires a comprehensive “fact base” of information on current and future heat risk. Cities then need to develop a diverse portfolio of heat mitigation and management strategies, which should reflect future uncertainties. These efforts should be coordinated across different departments, sectors, and plans. And these strategies need to be implemented, monitored, and evaluated over time since heat planning is new in most communities.

When it comes to selecting heat resilience strategies, cities have a variety of options. We group these into eight categories, half of which are focused on heat mitigation and half on heat management.

A diagram of eight strategies for urban heat resilience
Framework for urban heat resilience, with seven principles in the center and the eight categories of strategies (Ladd Keith and Sara Meerow)

When it comes to heat mitigation, the most commonly used strategy in the United States is urban greening, including urban forestry, green stormwater infrastructure, and other vegetation. But there are many other strategies that could mitigate heat including land use, urban design, and waste heat reduction. For example, efforts to enhance walkability and reduce vehicle use and building energy efficiency upgrades can also reduce waste heat.

Heat management strategies include policies and programs that focus on energy, particularly ensuring that residents have access to reliable and affordable indoor cooling, strategies geared towards reducing personal exposure to heat, public health, and emergency preparedness. Many communities are preparing for heat emergencies with early warning systems and cooling centers where people can shelter and seek assistance. Still, more emphasis may be needed on regulation to limit exposure and ensure that everyone can afford and access reliable indoor cooling.

Coordination is key

Effectively planning for urban heat resilience and implementing strategies will require that cities coordinate efforts across different disciplines and sectors, including planning, hazard mitigation, emergency management, public health, public works, parks and recreation, the energy sector, and many more.

Heat should also be addressed in all of the different community plans that shape the built environment and urban services — the network of plans. Thanks to the same NOAA grant that made it possible for the PAS Report to be free to download, we are also leading the development and piloting of the Plan Integration for Resilience Scorecard for Heat (PIRSH) methodology. PIRSH will allow planners to spatially analyze how different plans would affect heat risk and to identify policy inconsistencies. For example, one plan may call for additional vegetation to cool a particularly hot neighborhood, while another plan increases surface parking lots which could increase heat risks. We will publish a PIRSH guidebook and the Baltimore, Boston, Ft. Lauderdale, Houston, and Seattle pilot reports soon.

Time to act

All heat deaths are preventable, yet heat impacts will continue to increase unless cities around the world plan for urban heat resilience. Although heat governance remains fragmented and is still in its early days, we see promising signs that more communities are beginning to acknowledge heat as a hazard and take action.

Heritage Trees of Cape Town (Continued)

Many voices. Greener cities. Better cities.

Cape Town sprawls beneath the majestic Table Mountain in the heart of the mega-diverse Cape Floral Kingdom. With 3.74 million inhabitants, it is South Africa’s second most populous city. Despite the obvious ecological stressors resulting from the city’s high metabolism and rapid expansion (ca. 1.4% per year), a spectacular richness of biodiversity survives within and around the city limits.

Early European settlers of the Cape quickly denuded the region’s small patches of native forest. To compensate for this loss, they undertook several waves of planting, primarily for timber, fruit and shade but also for aesthetic beauty and defence (see tree No. 11 below). Consequently, many of the heritage trees found in Cape Town today have been introduced, typically from Europe or other distant parts of the world with historical trade links to the Cape. Yet even non-native trees can be valuable, especially in terms of ‘cultural ecosystem services’.

This article is a sequel to an earlier installment, entitled, Trees as Starting Points for Journeys of Learning about Local History, published on 1 September 2013. In that article, I explored the historical, cultural and spiritual dimensions of a selection of remarkable trees found in the vicinity of Cape Town, South Africa. I suggested that such trees have distinctive personalities, reflected in the various anecdotes that we attach to them; that they shed light on the cultural value systems and economic priorities of bygone generations; and that they provide excellent starting points for journeys of learning about a city, journeys that have no fixed route or endpoint.

I argue that such trees deserve greater recognition and protection for their part in enriching the urban landscape.

Here follows a selection of additional Capetonian Heritage Trees

9. Van Riebeeck’s Hedge

Africa is the cradle of humankind. There is evidence of modern humans living 130,000 years ago in the Western Cape and at least 30,000 years ago in what is now Cape Town. Comparatively recently, in the late 1400s, European explorers began foraying into the Cape coming face to face with the region’s indigenous people: interconnected communities of San (hunter-gatherers) and Khoikhoi (nomadic pastoralists), collectively known as Khoisan. Each summer, the Khoikhoi would bring herds of cattle across the Cape Flats to graze on the slopes of Table Mountain. Delighted to find a reliable supply of fresh meat, the Europeans quickly established trade with the Khoikhoi, exchanging metal for livestock. The first transaction is recorded to have taken place in December, 1497, in Mossel Bay.

In 1652, when Jan van Riebeeck of the Dutch East India Company (VOC) arrived at the Cape with orders to establish a victualing station, relations with the Khoisan took a turn for the worse. Essentially nomads without a written culture or bureaucratic governance system, the Khoisan did not have written title deeds. Accordingly, van Riebeeck contrived to deny the Khoisan their traditional land rights, provoking a revolt and ultimately bringing an end to a long period of reasonably friendly association (with some notable exceptions e.g. see No. 1, in Trees as Starting Points for Journeys of Learning about Local History). Cattle theft and bloody skirmishes became increasingly common. In 1660 Van Riebeeck ordered new defences to be built, including the planting of a Wild Almond (Brabejum stellatifolium) hedge around the perimeter of the settlement, encompassing an area of about 6 miles by two.

The Wild Almond is a member of the Protea family and closely related to the Australian Macademia Tree. It grows as much horizontally as it does vertically, posing an almost impassable barrier to cattle. Its wild fruits were harvested, specially prepared and eaten by the Khoisan. Today one can find remnants of Van Riebeeck’s Hedge on a leafy ridge in Kirstenbosch National Botanic Garden. There, a plaque reads:

For many, this hedge marks the first step on the road to Apartheid and symbolizes how white South Africa cut itself off from the rest of Africa, dispossessed the indigenous people and kept the best of the resources for itself. Our challenge in South Africa today is to dismantle the barriers erected in the past, share the resources equally and build a home for all.

10.  The Namesake of the Palm Tree Mosque

A raucous collision of colour where old meets new, tourists meet pickpockets, businessmen meet prostitutes, and drunkards meet drug-dealers: Long Street — the ‘beating heart’ of Cape Town — is not a savoury place. Yet skirting this canyon of intemperance, tucked among the busy restaurants, clubs and stores are architectural gems of great antiquity including one of the city’s most enduring and historic spiritual spaces: the Palm Tree Mosque.

Palm Tree Mosque circa 1876Palm Tree Mosque_Cape Times article of 1965Also known as the Dadelboom Mosque, it is the second-oldest place of Muslim workshop and one of the oldest substantially unaltered buildings in Cape Town (constructed c. 1780; second story added c. 1820).

Two tall palm trees (species unidentified) once towered above a small garden in front of the mosque. The garden is now pavement and only one of the original trees remains; the other fell victim to the fierce ‘south-easterly’ presumably in the early 1960s, as a framed photograph inside the mosque, suggests that a replacement tree was planted in 1965. Segments of the deceased tree’s trunk are seemingly used as stools inside the mosque.

In Islamic culture, palm trees are deeply symbolic: they appear around oases to signal water as a gift of Allah; they are said to grow in the Islamic paradise of Jannah; Muhammad built his home and the first ever mosque out of palm trees; the first muezzin would climb up palm trees to proclaim the call to prayer; and in the Quran (19:16–34), Jesus was born under a palm tree.

Under Dutch rule of the Cape, Islam could not be practiced in public. They banished one of the founders of Islam in the Cape, Tuan Guru (‘Mister Teacher’), to Robben Island where he famously wrote his own edition of the Quran from memory. Restrictions were relaxed when the British took control in 1795 and the free Tuan Guru soon established the Auwal Mosque (the city’s oldest mosque).

In the early 19th century, two freed slaves, Jan van Boughies and Frans van Bengalen, turned their backs on the Auwal Mosque after the former failed to succeed as imam. In 1807, they purchased the building which they would fashion into the Palm Tree Mosque. Records suggest that Van Boughies eventually owned 16 slaves, although some sources suggest that he only purchased them to set them free. Van Boughies died in 1846 at the age of 112, bequeathing the property to his wife under the condition that it would continue functioning as a mosque.

11.  The Money Tree in Kalk Bay

Money may not grow on trees, but it often changes hands beneath their branches. In the sleepy fishing village of Kalk Bay in the southern suburbs of Cape Town, the Money Tree — a Monterey cypress (Cupressus macrocarpa) — is said to have sheltered countless transactions.

DSC04227From the late 1600s to 1850s, Kalk Bay — as its name would suggest — supported a lime industry burning locally abundant seashells in kilns. With the demise of that industry, fishing emerged as the village’s economic staple. After each day at sea, it was under the Money Tree, safe from driving rain or blistering heat, that fishing boat skippers would dispense wages to their crews. So too, traders known as ‘langgannas’ — a Malay word reflecting Capetonian ancestry — would gather around the Money Tree to purchase cartloads of fish. These they would lug some 30 km north to Table Bay, blowing traditional fish horns at way stations to announce the arrival of their commerce.

Many of Kalk Bay’s ‘coloured’ residents survived the abhorrent Group Areas Act of 1966, receiving dispensation from forced removal. As such, Kalk Bay enjoys a cultural continuity unknown to other parts of Cape Town. However, decades of overfishing have dramatically reduced the size of the fishing fleet and the Money Tree now hangs rotting by the roadside, devoid of leaves, a skeleton of its former glory.

12.  The Kindergarten Giant

A century-old Moreton Bay Fig (Ficus macrophylla) — indigenous to the east coast of Australia — radiates from a kindergarten in the University of Cape Town. Scores of children find magic and adventure in the deep boughs and buttresses of its roots. With a girth (trunk circumference) of 16m and a crown of 41m, it is also known as the Big Friendly Giant. However this giant is dwarfed by its sibling living just a few miles away in Claremont’s Arderne Gardens (see No. 13).

Kindergarten Giant13.  The Colossi of Arderne

In the southern suburb of Claremont an extraordinary garden is home to some of South Africa’s most colossal trees.

Colossal Norfolk Island Pine of Arderne Colossal Fig of Arderne Colossal Aleppo Pine of ArderneThe Arderne Gardens were established in 1845 by the Englishman, Ralph Arderne, who had amassed a considerable fortune as a timber merchant. His trade enabled him to collect plants from all over the world and soon his garden became famous for its exceptionally-beautiful collection of exotic trees. Ralph Arderne died in 1885, but his son, Henry, continued to develop the garden well into the 20th century. When Henry died in 1914 on the eve of the Great War, it is said that one of the original Norfolk Island Pines which is father had planted, synchronously withered and died. The garden then passed to a property developer who threatened to divide up the land into building lots. However, much of the garden was salvaged when, buoyed by a public outcry, the City’s Director of Parks and Gardens, Mr. A. W. van den Houten, persuaded the City Council to purchase the most important part. For the following 27 years, the garden was curated by M. A. Scheltens, who is said to have forgone several promotions in order to stay with the trees he so loved.

Today, the Arderne Gardens remains one of Cape Town’s most popular green spaces, drawing sunbathers, picknickers, joggers and dog-walkers. Over weekends dozens brightly-coloured wedding parties pose for photo-shoots in the garden. One of the garden’s huge Norfolk Island Pines (Auraucaria heterophylla) features so regularly as a backdrop, that it is now colloquially known as the “Wedding Tree”. Of the many impressive trees in the Arderne Gardens, some are particularly huge. For instance, the world’s largest Aleppo Pine (Pinus halepensis) — native to the Mediterranean region — forms a giant corner-post of the garden, not far from the largest individual tree in the Western Cape and possibly South Africa: the Moreton Bay Fig (Ficus macrophylla).

HERITAGE: Downtrodden and Torn Down

Many voices. Greener cities. Better cities.

Sydney is in heritage crisis mode. Ancient Aboriginal campsites are being dug-up and destroyed. Low-income residents are being forcibly removed from their long occupied, heritage-listed, city-centre homes and apartments. Magnificent and much-loved trees are being uprooted from their parkland settings. These actions are having emotional affects for individuals and communities, undermining people’s feelings of well-being, and changing the livability of the city. So what the heck is going on?

As Sydney is demonstrating, heritage in the form of objects, structures, or people’s feelings for place, is a litmus test of change.

The International Council on Monuments and Sites (or ICOMOS), a global network of heritage professionals that work for the conservation and protection of cultural heritage places, has shown that heritage can be a driver of development. ICOMOS has implemented a series of initiatives and actions over many years that promote a development process that incorporates tangible and intangible (or non-material) cultural heritage as a vital aspect of sustainability, and gives a human face to development. Despite this work, governments such as the New South Wales (or NSW) State Government are undermining heritage by re-enacting an old but pervasive binary—population growth and infrastructure improvement versus amenity and heritage. This is a long-held and artificially constructed political opposition that positions heritage as an inhibitor of development.

In this essay, I consider recent cases of loss of Sydney’s significant heritage items—stone artefacts, buildings, and trees—and the consequence these losses are having on peoples’ lives. In these examples the NSW State Government’s decisions are reversing long-fought-for gains across social justice matters and severing community connections to important places. Such losses, it seems to me, are happening even faster than global warming can erode Sydney’s coastlines. I argue for a return to an ethics of respect and care in urban planning and change management so as to better marry heritage, development and community well-being.

I have been a resident of Sydney for over 16 years. I love this city (though clearly I have issues with it). By training and experience, I am an archaeologist-heritage practitioner and academic. My interests centre on the ways that material remains and community practices affect peoples’ everyday lives. Work in the fields of psychology and heritage studies has demonstrated the ways in which people develop emotional attachments to special things, such as inherited objects or important places—for example, people’s homes and gardens, particular plants and trees or urban open green spaces. I am not an urban planner, but my interests are in the emotional-sensuous landscape of urban dwellers and how feelings as much as urban fabrics permeate the contemporary cityscape.

Are you Sirius?

The Sirius Building, a brutalist-style structure located adjacent to the iconic Sydney Harbour Bridge, is slated for demolition. The building is a public housing complex designed in 1979 by NSW State Government Housing Commission architect Tao (Theodore) Gofers. The design was influenced by Moshe Safdie’s Habitat 67 building in Montreal, Canada. The Sirius Building is a series of concrete boxes that together provide 79 apartments capable of housing 200 people. The structure is also notable for its green credentials—plants sit between the occupied spaces and surround the base of the building.

In March 2014, the NSW State Government announced plans to sell the Sirius Building site and, in 2015, tenants of the public housing complex were relocated. In 2015—albeit somewhat late in the game—the Heritage Council of NSW unanimously decided to recommend the Sirius Building for state heritage listing based on two key criteria—aesthetics and rarity. Surprisingly, they omitted the “key” criteria of “social value”, a phrase encompassing the significance of places to contemporary communities. Regardless, the Heritage Council’s recommendation was submitted to the NSW Minister for Environment and Heritage. The Minister declined to heritage list the building, citing economic rationalist reasons (heritage listing would reduce the site value by approximately AUS $70 million, a figure equivalent to 240 social housing units). It would seem that in this case, money has spoken, and the residents and communities of interest have wielded little influence or power.

To my mind, there are several disturbing aspects to this process and decision. First is the State Government’s rejection of the expert perspective of the Heritage Council of NSW, a body established to advise the government on such matters. In refusing to list, the Minister avoided adopting an ethical and courageous position of accepting the heritage value of the building based on expert and community viewpoints and then arguing for its demolition. The Minister’s decision making shows that he does NOT respect expert and community viewpoints. Second, the value of the building to its residents, many architects, and the wider City of Sydney were “overlooked” in the decision not to list the building. City of Sydney Lord Mayor, Clover Moore, has expressed support for the retention and heritage listing of the building, stating: “The original design and use of the Sirius building for apartments means it is capable of reasonable and economic use for housing. Its retention will continue to contribute to the character and housing diversity of The Rocks and Millers Point.”

A decision to demolish the Sirius Building is, in my view, an act of meanness. The decision ignores the personal impacts on recent and long-term residents. It also reflects an attitude antithetical to ideas of trust, humility, and integrity that many of Sydney’s residents, including me, want to see practiced by government.

Out with the trees

In early 2016, roughly 40 mature Moreton Bay Fig trees (some more than 130 years old) were removed and/or slated for removal from in and alongside Moore Park in Sydney. The Park, dedicated in 1866, has a long history of use for recreational activities (such as picnics) and outdoor sports. It is also renowned for its landscaping and functioning as an urban green open space. In May, public protests against the ongoing removal of trees led to the arrest of one person. Local resident and campaigner Annie Hargue has spoken of the loss of trees as a “very emotional issue”.

The removal of the trees is associated with the State Government’s development of an extended light rail system, itself a much-lauded project by those supporting improved public transport schemes. However, the issue is one of community engagement at a sufficiently early stage in the project planning. It would seem that community consultation, itself a rather cynical exercise when it is not undertaken in a truly collaborative spirit, was an abject failure. The State Government simply did not determine the social and community value of the trees. Instead, there is a sense of tree removal by stealth, which is not uncommon in governmental decision-making practice, but which is also at odds with the idea of transparency and accountability so often touted in government strategy and public declarations.

A subsequent “offer” to replant “significantly more” trees by the State’s Premier seems to have come too late and in an effort to compromise rather than out of generosity. This replacement option might have been acceptable to the majority of community members if a respectful process of civic engagement had been undertaken. In this failing, I see echoes of the meanness associated with the Sirius Building decision.

Trampling spirits

A further impact of this same light rail development project, but this time in the Sydney suburb of Randwick—several kilometres from Moore Park, has been on Australian Aboriginal (or Indigenous) cultural heritage. Heritage investigations undertaken in advance of the project resulted in the excavation of large numbers of Aboriginal stone artefacts. The exact numbers of artefacts are disputed, though a figure of 20,000 is commonly cited in the media. Nevertheless, and regardless of the exact number, such artefacts are taken to be markers of Aboriginal presence by present day Aboriginal people, representing a mix of settlement activities and ritual ceremonial practices. They are evidence of Aboriginal peoples’ occupation at the find location in the period prior to the 19th century, and likely many thousands of years previous. Aboriginal Elders have called for the protection of the artefact site because of its importance to contemporary Aboriginal people.

For many Aboriginal people, stone artefacts, whether formal tools or the waste products of tool manufacture and use, have come to represent the presence of real and spiritual ancestors. Furthermore, for some, stone artefacts act as agents with a capacity to channel the power and spirituality of ancestors and the place itself. I am not familiar with the excavated site referred to above, nor do I know the people for whom it evokes powerful feelings. However, Aboriginal peoples’ emotional attachment to such places is a vital expression of reconnection to urban landscapes, from which Aboriginal owners and custodians were dispossessed following the non-indigenous invasion and occupation of Australia from 1788.

Despite such connections felt by contemporary Aboriginal people to the stone artefacts and the place, the Federal Environment Minister, responding to a call for protection, has expressed the opinion that “I am not satisfied that the area …is a significant Aboriginal area as defined” (in relation to relevant legislation). There are echoes here of a long-standing colonial position that Aboriginal stone artefacts are of the past and are not relevant to contemporary Aboriginal people who are, in this instance, urban dwellers. This is a false presumption and reflects an attitude that urban Aboriginal people are not “traditional”, and are therefore incapable of reformulating and renewing their cultural connections to place.

Meanness, lack of generosity, and ongoing dispossession

Sydney’s expansion of its light rail system, though not a bad thing in itself, is coming at an emotional cost to communities, just as the proposed removal of the Sirius Building is undermining a sense that government actions respect civil rights. Such actions have become more common, rather than less so, over the last decade.

Australian heritage practitioners have a global reputation for their work in recognizing and documenting community values for special places. These skills have been developed since the early 1990s and offer workable approaches to engaging communities in identifying and managing important places and landscapes. Such work is typically characterized in heritage terms as “change management”, a phrase that talks to the dynamic and negotiated nature of heritage. Such skills should be regularly called on when discussing the values of public housing structures, Aboriginal cultural heritage, and long-standing trees. To be fair, much is already done in this regard. However, more recently, the balance between positive and negative outcomes for much-loved places is shifting toward the latter. The consequence is that community values and connections to special places are being increasingly sidelined in the processes of change in Sydney’s inner city environment.

Thus, Sydney is demonstrably moving toward a less-civil civil society. Heritage, whether as objects, structures, or people’s feelings for place, is a marker or litmus test of change. What is emerging is a growing tendency towards meanness or lack of respect for community views, a lack of generosity to the less-wealthy parts of society, and an ongoing practice of destruction of Aboriginal heritage. Not only are these things happening, but people are being deeply hurt in the name of a “better” society: an uncivil, civil society.

But I remain an optimist and a believer in the power of peaceful civic action and the capacity of government’s to respect expert and community viewpoints. Skill sets, tools (such as cogent planning based on community impact studies) and political processes exist for building closer ties between governments, heritage professionals, and those communities with intimate connections to special places. It is inspiring to see, for example, the recent placing of a “green ban” on future redevelopment of the Sirius Building site by the Construction, Forestry, Mining and Engineering Union (The Herald Sun, 18 September 2016, page 2). At a rally held on Saturday 17 September, Jack Mundey, renowned for coining the term “green ban” during urban heritage campaigns of the 1970s, told the crowd, “It’s a great pleasure for an old 87-year-old-bloke to be here. Let us resolve to keep the fight going.”

On The Nature of Cities

Highlights from Ten Years at The Nature of Cities

Many voices. Greener cities. Better cities.
As we work to heal the earth, the earth heals us. ― Robin Wall Kimmerer

The Nature of Cities was launched 10 years ago, in June 2012. I believe it has been a success, with over four million reads and around 1,000 contributors. I believe it has been valuable in framing and propelling dialogue in its promotion of collaboration and transdisciplinarity that are essential to cities that are better for both people and for nature; cities that are resilient, sustainable, livable, and just.

It is the long history of humankind (and animal kind, too) that those who learned to collaborate and improvise most effectively have prevailed. — Charles Darwin

All four.

Not just the one or two we might pursue from the confines of one discipline, but all four, which can only achieved by reaching beyond the edges of our knowing to engage with someone else’s. Indeed, the wicked problems we so often talk about these days would seem to logically demand similarly rich approach to solutions — that is, transdisciplinary solutions that are as complex and nuanced as the problems.

The world is before you and you need not take it or leave it as it was when you came in. — James Baldwin

The three quotes you see to the right knit together, for me, a sense of we can achieve if we (1) seek inspiration in nature; (2) share, collaborate, and innovate with each other; and (3) are fierce with ourselves about the imperative of progress. These ideas have been driving forces in the ongoing evolution of TNOC.

We have published almost 1,300 essays and roundtables in these 10 years, and worked on a variety of projects. I believe that all work at TNOC has great value; the 30 pieces highlighted here represent a selection that were particularly widely read, singular, or key in some way. There are many others that could easily have made this list.

Check out highlights from each of our first ten years: 2021, 20202019,  2018, 20172016, 2015, 2014, 2013, 2012.

Onward and upward, we can hope. In our work we continue to seek the frontiers of thought and action found at the fizzy boundaries of science. practice, community, design, planning, infrastructure, and art.

Thank you for participating with us over 10 years. Let’s continue to collaborate and act for progress.

* * *

Ten years ago, the birth of TNOC was fired by conversations with many people, but two in particular: Mike Houck in Portland, and Erika Svendsen in New York. From Houck, I received his passion about fierce activism in service of a nature that was right outside the door; an urban nature that wasn’t many miles away, accessible to only a few, but right outside. The idea of accessible nature nearby is foundational to any concept of urban environmental justice. From Erika, I was moved by the idea of people working together in community to create and steward the natural work around them. An urban environment that centers both nature and people is key to any real progress in green and livable cities. Erika, Lindsay Cambell, and Liza Paqueo of the the US Forest Service are among TNOC’s greatest friends.

There are many more people I appreciate for influencing what TNOC has become, growing from 12 writers to over 1,000. First to mention is our board: Mike Houck (Portland); Martha Fajardo (Bogotá); Mark Rowe (Toronto); Marcus Collier (Dublin); Siobhán McQuaid (Dublin); Chantal van Ham (Brussels); Gilles Lecuir (Paris); Pippin Anderson (Cape Town); and Huda Shaka (Dubai) — plus former board members Thomas Elmqvist (Stockholm); Rodolpho Ramina (Curitiba); Valerie Gwinner (Washington/Vaison du Romain); and David Tittle (London). A million thanks also to remarkable core TNOCers M’Lisa Colbert, Patrick Lydon, Carmen Bouyer, Claudia Mistelli, Karen Tsugawa, and Emmalee Barnett.

Finally, thank you to all our sponsors and partners. You can see who they are at the footer of this page.

The Nature of Cities Festival

We have presented three large global events at TNOC, starting with TNOC Summit in Paris in 2019. Two versions of an entirely virtual TNOC Festival followed in 2021 and 2022. The common thread in the three was a commitment to having many different ways of knowing and modes of action all at the same meeting. We also, especially in the virtual Festivals, tried to make sure that everyone could participate to disrupt the notion that international urban meetings were only available to the people who can afford them. Key to us is lowering barriers to participation.

Roundtables

Graffiti and street art can be controversial, but can also be a medium for voices of social change, protest, or expressions of community desire. What, how, and where are examples of graffiti as a positive force in communities?

Graffiti and street art can be controversial. But it can also be a medium for voices of social change, protest, or expressions of community desire. What, how, and where are examples of graffiti as a positive force in communities?

In many cities, graffiti is associated with decay, with communities out of control, and so it is outlawed. In some cities, it is legal, within limits, and valued as a form of social expression. “Street art”, graffiti’s more formal cousin, which is often commissioned and sanctioned, has a firmer place in communities, but can still be an important form of “outsider” expression.

Do urban green corridors “work”? It depends on what we want them to do. What ecological and/or social functions can we realistically expect green corridors to perform in cities? What attributes define them, from a design and performance perspective?

Corridors have been promoted by conservation biologists to restore connectivity of habitats and to facilitate the movement of plants and animals. The exchange of genetic material between spatially distinct communities has a fundamental impact on ecological processes such as diversity-stability relationships, ecosystem function, and food webs.

Urban green corridors are a good example of where we jump ahead to solutions before defining the problem. Before calling for the establishment or protection of corridors, it’s important to consider what kinds of ecological and social objectives we want in our cities. I think that green corridors have great potential because they can perform multiple functions. However, exactly what these desired functions are needs to be clearly defined first before guidelines for their design can be set.

Artists and scientists that co-create regenerative projects in cities? Yes, please. But how?

We asked a collection of scientists and artists, each actively engaged in some form of art-science collaboration, how they approach it. Some are artists, some are scientists, some are both. All are interested in exploring a fizzy boundary of expression at the intersection of artistic and scientific approaches to storytelling.

Key to the question of this roundtable: can we be changed by interactions with other ways of knowing, changes in ways that would enrich both useful knowledge and our interdisciplinary practice?

Urban agriculture has many benefits. Is one of them a contribution to urban sustainability?

Sustainability is key to our future, and, as urbanization steadily grows, keys to increased global sustainability must be found in cities and how they use and are provided with resources. In this area there has been much excitement about urban agriculture, which for our purposes here we will define as the production of food in and near cities at scales larger than home or community gardens.

There are many potential benefits to such efforts, including the support of social movements; economic development; creation of local businesses and jobs; environmental education; community building; and local food security. But does urban agriculture have the potential to contribute significantly to urban sustainability by reducing cities’ dependence on food grown at great distance from the city? Can it produce enough to address food insecurity?

Are cities ecosystems—analogous to natural ones—of nature, infrastructure and people? Does thinking about cities in this way help us think about urban design?

Are cities ecosystems in the senses in which we think of classic natural and ecological areas outside of cities? After all, urban spaces are connected mosaics of green space, biodiversity (including people), non-biological structure, biophysical processes, energy flows, and so on. That sounds a lot like a natural ecosystem.

But perhaps more importantly, does thinking explicitly about cities as ecosystems help us? Does it offer us any insight into urban design? For example, are our goals for cities—sustainability, resilience, livability, and justice—advanced by an urban ecosystem concept?

Why don’t all public buildings have green roofs? Or all large private buildings (e.g. businesses)? Would this be a good idea? What would it take to make it happen and to make it worthwhile?

Many of the benefits of green roofs are appreciated and increasingly well-studied: stormwater management, mitigation of heat islands, insulation, biodiversity, increased longevity of the waterproof membrane, green space for enjoyment, and so on.

With all these benefits, why don’t more buildings—especially large ones—have green roofs? Shouldn’t they? Should all public buildings and large new construction be required to have green roofs?

Answering these questions obviously requires complicated technical and political calculations about the real and perceived values of green roofs, what they cost to build and maintain, and whether greens roofs are “worth it”.

Covid has upended all the normal routines in our lives and work. How do you imagine you might be changed by it, both professionally, but also personally as you negotiate a new post-virus “normal”?

We are all confined to our homes—if we are lucky. Which is something, since most of us are “outdoor types”, “people types”. Can we find meaning, motivation, and renewed spirit for action in this contemplative but deeply strange time? We find ourselves wondering, doubting, planning our next steps or perhaps second-guessing our last ones. We are trying to keep all the parts of lives still stuck together and not flying apart.

Now that we have seen how our cities around the world truly function at their most vulnerable, what possible excuse do we now have to not emerge solely committed to fixing it? Maybe in searching for a new post-Covid “normal”, we need to act on the idea that the old normal was a big part of the problem.

You say po-TAY-to. What ecologists and landscape architects don’t get about each other, but ought to.

In the creation of better cities, urban ecologists and landscape architects have a lot in common: to create and/or facilitate natural environments that are good for both people and nature. Mostly. Some may tilt toward the built side, some to the wild. Some may gravitate to people, others to biodiversity, form or ecological function, or social function, or beauty.

There are a lot of shared values. And yet, they are still two distinct professions, ecology and design, and so there are ways in which we may say similar sounding things but mean something different. What is something your partner in environmental city building, the other profession, just doesn’t get about you? And what would it take it fix it?

Artists in Conversation with Water in Cities

As human beings who inhabit bodies made mostly of water, connecting to water as an element means connecting to a large part of who we are. Yet more than this, the artists in this roundtable teach us that if we pay close attention, water can help us connect in profound and useful ways to the environments around us.

Water is vital, spiritual, and restorative. It is a common that connects us all, to each other, and to our biosphere. The conversations here take various forms, from the performative to the media-based, from poems to sculptures to design, and from community and civic engagement, to methods of collaborative caring for water and for each other. We are pleased to have you discover these conversations with us, and invite you to further enrich them by responding to the work and perspectives together.

Common threads: connections among the ideas of Jane Jacobs and Elinor Ostrom, and their relevance to urban socio-ecology

Jane Jacobs and Elinor Ostrom were both giants in their impact on how we think about communities, cities, and common resources such as space and nature. But we don’t often put them together to recognize the common threads in their ideas.

Jacobs is rightly famous for her books, including The Death and Life of Great American Cities, and for her belief that people, vibrant spaces and small-scale interactions make great cities—that cities are “living beings” and function like ecosystems. Ostrom won a Nobel Prize for her work in economic governance, especially as it relates to the Commons. She was an early developer of a social-ecological framework for the governance of natural resources and ecosystems. These streams of ideas clearly resonate together in how they bind people, economies, places, and nature into a single, ecosystem-driven framework of thought and planning

Read this! 90 recommendations for the one book about (or relevant to) cities that everyone should read

We have assembled a list of 90 must-reads on cities from a diverse group of TNOC contributors—a nature of cities reader’s digest. The recommendations are as wide-ranging as the TNOC community, from many points of view and from around the world. They are a reflection of the breadth of thought that cities need. And, as my grandmother would have said: “This will keep you off the street and out of trouble”.

The prompt seems easy, but it turns out to be difficult to recommend the one thing everyone should read on cities, and what we have created here is a remarkable and diverse reading list. You will likely think of other essential works yourself, and when you do, leave them here as a comment.

Beyond equity: What does an anti-racist urban ecology look like?

There has been a growing belief in the need for “equity” in how we build urban environments. The inequities have long been clear, but remain largely unsolved in environmental justice: both environmental “bads” (e.g. pollution) and “goods” (parks, food, ecosystem services of various kinds, livability) tend to be inequitably distributed. Such problems exist around the world, from New York to Mumbai, from Brussels to Rio de Janeiro to Lagos. Indeed, among many there is a sense that “equity” is not enough. Perhaps we need a more active expression of the social and environmental struggles that that underlie issues of equity and inequity in environmental justice and urban ecologies: one that is explicitly “anti-racist”, and which recognizes and tries to dismantle the systemic foundations of the inequities.

The Just City Essays

The Just City Essays: 26 Visions for Urban Equity, Inclusion and Opportunity was a collaboration  of the J. Max Bond Center on Design for the Just City at the City College of New York, The Nature of Cities, and Next City; funded by the Ford Foundation. It has been among the most widely read publications at TNOC, and among other things, was the required reading of all freshman at Stanford University in 2019.

Art and Exhibits

Science does not know its debt to imagination. — Ralph Waldo Emerson

As COVID-19 began, The Urban Ecological Arts Forum at The Nature of Cities, sometimes known as FRIEC, started bringing to life virtual exhibition spaces, highlighting current exhibitions on urban ecological themes that would otherwise be impossible to experience due to the closure of cultural facilities. We have expanded this idea of a regular series or “installations” that traverse the shared frontiers of art, science, and practice. This commitment to art engagement has expanded to fiction, poetry, comics, graffiti, and, in collaboration with the US Forest Service, artist residencies.

City in a Wild Garden: Stories of the Nature of Cities, Vol. 2

This is our second volume of short fiction about current and future cities. We wanted to explore how to imagine cities. We asked authors to be inspired by an imagining, an evocative phrase: “City in a wild garden.” In this volume, there are stories of transformation, loss, and despair, and also stories of great beauty and hope, with nature and people that emerge from trials, in which people and the wild have merged in fundamental ways. Forty-nine stories from 20 countries are in this book, including the six that we judged to be “prize-winners,” by authors from the United States, India, and Brazil.

SPROUT: An eco-urban poetry journal

SPROUT is an eco-urban poetry journal that curates space for trans- and multi-disciplinary collaborations between poets, researchers, and citizens with a focus on geographical diversity, polyvocality, and translation. For the first volume, in inviting new work to reflect expansively about space, the contributors took up the call to carve out space(s) for themselves. The collected product reflects a multitude of poetic practices. What brings them all together is a particular attentiveness to the liminal, the in-between, the beingness of being-in-space, and acts of seeing out (or, indeed in) wards, into space.

Hidden Flows — photographers uncover the invisible flows in African cities

The hidden flows exhibition emerged out of a need to enrich current conversations about resources, infrastructure and services in African cities. There is ongoing research, through the lens of urban metabolism, to measure and track how resources flow through our cities, in order to support decision making and policy generation. Traditional urban metabolism research approaches rely on extensive quantitative data. Gathering these data accurately is difficult in most cities and even more so in African contexts because of the way resources move – not through typically piped and cabled network infrastructures – but in ways which are reliant on decentralized systems and on private [informal] individuals and organizations.

NYC Urban Field Station—Who Takes Care of New York?

This exhibition was originally mounted at the Queens Museum in September 2019, and highlights the stories, geographies, and impacts of diverse civic stewards across New York through art, maps, and storytelling. The virtual iteration which you are about to experience is provided through a collaboration between the Forum for Radical Imagination on Environmental Cultures (FRIEC) at The Nature of Cities, and the USDA Forest Service, NYC Urban Field Station.

The show features artists whose work aligns with the themes of community-based stewardship, civic engagement, and social infrastructure: Magali Duzant, Matthew Jensen, Jodie Lyn-Kee-Chow, and Julia Oldham. Through photography, drawing, book arts, and performance, these artists reflect upon, amplify, and interpret the work of stewards and the landscapes and neighborhoods with which they work.

Shade in the City: Rising Heat Inequity in a Sunburnt Era

To tackle the issue of urban heat, a group of 18 artists and activists in Los Angeles’ vibrant Highland Park neighborhood raised awareness of shade as an equity issue in an outdoor public art installation called Shade in LA | Rising Heat Inequity In A Sunburnt City.

In a warming world, shade equity is an issue that disproportionately affects low-income and working-class communities, people of color, and communities in developing nations who are more likely to work outdoors, rely on public transportation, and live in denser neighborhoods with a lack of trees and shade.

Nikki Lindt—The Underground Sound Project

The Underground Sound Project, featured on CBS Mornings, is a collection of underground sound recordings made by artist Nikki Lindt over the course of the past year in the five boroughs of NYC and in rural Cherry Valley, NY. The recordings are made by placing microphones underground, underwater and even inside trees.

The Soundwalk is experienced along the trail in Prospect Park, NY. Along the path you will encounter features, such as a stream, old growth tree, soils, wildflowers, and many more. Via a sign with a QR code at designated locations along the walk, you will be able to experience the corresponding subsurface sounds. The soundwalk can also be experienced remotely with headphones.

Sense of Place
Jennifer Adams, New York. David A. Greenwood, Thunder Bay. Mitchell Thomashow, Seattle. Alex Russ, Ithaca

A place may also conjure contradicting emotions—the warmth of community and home juxtaposed with the stress of dense urban living. Sense of place—the way we perceive places such as streets, communities, cities or ecoregions—influences our well-being, how we describe and interact with a place, what we value in a place, our respect for ecosystems and other species, how we perceive the affordances of a place, our desire to build more sustainable and just urban communities, and how we choose to improve cities.

Hammarby Sjöstad — A New Generation of Sustainable Urban Eco-Districts
Maria Ignatieva, Uppsala. Per Berg, Sweden

Hammarby sjöstad (Hammarby Lake City) is an urban development project directly south of Stockholm’s South Island. This is no doubt the most referenced and visited spot among Scandinavian examples of implemented eco-friendly urban developments. Today, the Lake City offers a more sustainable framework for everyday life compared to the average Swedish city but hardly challenges its inhabitants to lead a more resilient life.

Vacant Land in Cities Could Provide Important Social and Ecological Benefits
Timon McPhearson, New York

Vacant land has been overlooked for far too long. If cities were to invest in the social-ecological transformation of vacant land into more useful forms, they would be creating the potential to increase the overall sustainability and resilience of the city. Depending on the kinds of land transformations urban planners and designers dream up, vacant land could provide increased green space for urban gardening and recreation, habitat for biodiversity, opportunities for increasing water and air pollution absorption and many other regulating, provisioning, and cultural ecosystem services.

Four Ways to Reduce the Loss of Native Plants and Animals from Our Cities and Towns
Mark McDonnell, Melbourne. Amy Hahs, Ballarat

The actions we undertake under the banner of “creating biodiversity-friendly cities” are about more than just conservation, they are about managing urban biodiversity in a broader sense. Frequently in our discussions of this topic, two distinct but interdependent ideologies tend to emerge. First, we begin by talking about how to preserve the area’s unique plants, animals and ecosystems, which is largely the foundation for the conservation objective in managing biodiversity. However, discussions are increasingly incorporating a second notion, which centres on our motives for managing biodiversity, and in urban areas these are largely expressed as a desire to manage biodiversity for the multiple benefits it provides to people.

The Green Cloud, A Rooftop Story from Shenzhen: A “Living” Sponge Space Inside an Urban Village
Vivin Qiang & Xin Yu, Shenzhen

The Nature Conservancy (TNC), along with other key partners, launched an innovative pilot projec—Green Cloud—on an old building in Gangxia village, transforming its rooftop into a “living sponge” space. The project utilizes three-dimensional light steel structures that are simple to construct and have the capacity to hold over 420 plant containers filled with plants mostly native to Southern China. The original concrete rooftop is transformed by vegetation, which is capable of absorbing and preserving rainwater, creating a nature-based stormwater management system for the residential building, achieving a 65% of run-off control rate. As a result, a living “green cloud” is formed on a rooftop of Gangxia village.

Nature in View, Nature in Design: Reconnecting People with Nature through Design
Whitney Hopkins, London

Poorly conceived design visibly divided us in urban areas from our wilds and contributed to our recent ability to see nature as something isolated from us. Yet reinvigorating our bond with nature is a challenge architecture and urban design are well placed to address. Architects and designers have control over our built environment; by changing the way we design cities and buildings to connect to rather than disconnect from nature, we can change our proximity to nature and shift our physical relationship to the environment.

Secular, Sacred, and Domestic—Living with Street Trees in Bangalore
Suri Venkatachalam & Harini Nagendra, Bangalore

In rapidly growing Indian cities, change seems like the only constant. Heritage buildings are torn down, roads widened, lakes and wetlands drained, and parks erased to make way for urban growth. Nature is often the first casualty in a constant drive towards development. Yet the street tree stubbornly survives across Indian cities. The lives of street trees are emblematic of the multiple entanglements that characterise the nature-society dialectic animating the ever expanding urban in the global south—entanglements that knit together the past and present, the secular and sacred, and the global and local.

Architecture and Urban Ecosystems: From Segregation to Integration
Kaveh Samiei, Tehran

During modern era of human development, growth of towns and cities displayed a separation between nature and human activities. This was not the case in premodern times, when human settlements either integrated or co-existed peacefully with the nature. The realization that nature embraces the city has powerful implications for how cities are built and maintained and for the health, safety, and welfare of each resident. Social factors are a key component of a viable and healthy eco system.

Though There is Method, There is Madness In It: How Silos of Methods Impede Cross-Cutting Research
Pippin Anderson, Cape Town

I believe, indeed fear, that until we are happy to really acknowledge the value of each other’s method, any real transdisciplinary engagement, so critical to urban ecology and more broadly global sustainability, will continue to elude us. Simon Lewis (quoted in Zoe Corbyn’s piece “Ecologists shun the urban jungle”), commenting on the failure of ecologists to engage in the social really, calls us on it when he attributes this to the fact that it helps make complex systems more analytically tractable.

In other words, when upacking a complicated multidisciplinary problem, we often have more fealty to the method that to understanding.

They are Not “Informal Settlements”—They are Habitats Made by People
Lorena Zárate, Mexico City

Recognized as a global phenomenon, no country can claim to be free of informal settlements, although the numbers of people suffering can vary largely depending on the region: these problems now affect up to 60 percent of the world’s population—or even more—in some Sub-Saharan African and Southeast Asian cities, and the number of people affected in these locations is expected to double over the next two decades. Neither informal nor irregular, these are, above all, human settlements. Or even better: they are the city produced by the people: the people who claim their rights to live, build, and transform the city.

Urban Metabolism: A Real World Model for Visualizing and Co-Creating Healthy Cities
Sven Eberlein, San Francisco

While figuring out the intricacies of our own body’s metabolism is no simple feat, doing a holistic assessment of something as complex as a modern industrial city, with all its physical and cultural microcosms, can seem daunting.  With citizen-generated maps and diagrams based on real-life conditions and structured around a holistic framework, the patterns that emerge allow for both residents and planners to ask questions that can lead to both local and regional ecological improvements.

In It Together
Lesley Lokko, Accra

The same broad categories of infrastructure, environment, equality and access to amenities apply to all urban centres, almost irrespective of scale. Yet there’s something in—or of/about—The African City that defies easy categorisation. African cities, to paraphrase Soja above, are places where “everything comes together,” in an almost dizzying panoply of contradictory binaries. Black/white; rich/poor; chaotic/controlled; hi-tech/lo-tech, as though there is no space or appetite for the nuance, the in-between, or the subtleties that make up any urban narrative in which most citizens somehow locate, negotiate and recognise themselves.

Crisis Reveals the Fault Lines of Gender in Environmentalism—How Do We Value Everyday Environments?
Nathalie Blanc, Sandra Laugier, Pascale Molinier & Anne Querrien, Paris.

These are times of crisis. One might even think that the COVID-19 crisis looks like a an alternative expression of crises that are already building, especially ecological ones. Neglecting gender and the unequal dimension of access and decision-making rights would doom environmental movements to failure. Let us be imaginative. What does it mean to revisit what the promise of equality means in terms of integrating the importance of gender in socio-environmental inequalities?

Open Mumbai: Re-envisioning the City and Its Open Spaces
PK Das, Mumbai

41% of the total land area in the densely built city of Mumbai must be reserved as open spaces. A change in the mindset, along with not so radical changes in the development plan, can make this city very eco sensitive and a sustainable urbanized centre to live in. The ‘Open Mumbai’ plan takes into consideration the various reservations in the existing development plan of the city. The recreation grounds, playgrounds, gardens, parks, rivers, nullahs, hills are already marked in the development plan; we are recognizing them and linking them with marginal open spaces and pavements along roads.

Crows of Vancouver: The Middle Way Between Biophobia and Biophilia
Christine Thuring, Vancouver

One of Metro Vancouver’s greatest spectacles is its twice daily crow migration that occurs every dawn and dusk, 365 days a year. Whereas biophilia is a popular meme for urban and ecological design, rarely is biophobia addressed. Perhaps it’s easier to pretend the “undesirables” don’t exist, but that’s just not realistic. The “crows of Vancouver” posed a reality check on the consistency of my narrative. In this era of biodiversity loss and the rising consequences of an over-engineered world our most common species represent an opportunity to reconnect with the dwindling wildness of the Anthropocene.

Water Marks: An Atlas of Water for the City of Milwaukee
Mary Miss, New York

As an artist, having the opportunity to develop a project at the scale of a city has been a remarkable experience. WaterMarks has grown out of a three-year engagement with the city of Milwaukee. City government, academic institutions, and many nonprofits have been essential contributors to the development of this urban-scaled project. Focusing on water, the project has three important goals in mind: address environmental issues as a gateway to sustainable development; engage communities as active partners; help identify Milwaukee as a global water center. Call and response is a means of dialogue: Physical interventions call out some aspect of the natural systems and infrastructure and, through community engagement activities, the people of Milwaukee respond to and activate the sites.

Hearing from the Future of Cities
Diana Wiesner, Bogota

Fundación Cerros de Bogotá has been inviting children from Bogota and the surrounding region to paper our walls with their landscape drawings. Last year alone, children from diverse backgrounds sent us more than 2,000 drawings of Bogotá’s mountains and their surroundings. In pondering all of these children’s drawings and listening to their stories about their interests, we began to realize that these children would be our greatest allies in bringing about the changes we have been dreaming about.

Photo Essay: Untold Stories of Change, Loss and Hope Along the Margins of Bengaluru’s Lakes
Marthe Derkzen, Arnhem/Nijmegen

Before becoming India’s information technology hub, Bengaluru was known for its numerous lakes and green spaces. Rapid urbanization has led to the disappearance of many of these ecosystems. Those that remain face a range of challenges: residential and commercial construction, pollution and waste dumping, privatization, and so on. Today, Bengaluru’s lakes are principally seen as garbage dumps and sewage ponds that can have either of two fates: one, be transformed into recreational oases to suit the needs of wealthy residential neighborhoods, or two, be encroached upon until none of the original shapes and functions can be traced. But how does this affect the lives of the people living at the very margins of Bengaluru’s beloved yet contested lakes?

Anatomy of a Mural: A Seventy Foot Heron Transforms a Lifeless Wall
Mike Houck, Portland

I frequently lead natural history walks around the 160-acre Oaks Bottom Wildlife Refuge, Portland’s first official urban wildlife refuge that lies on the east bank of the Willamette River, not far from the city center. The mural overlooks the refuge and the tale of its origins invariably intrigues my guests. I certainly learned a lot by working with muralists, artists, building owners, foundations, and the public while helping create the 55,000 square foot wetland mosaic. When it comes to community murals, nothing substitutes for persistence and perseverance. But the results are worth the effort.

Biophilia Revived: How Do We Strengthen the Connection to the Natural Environment in a City Expanding in the Desert
Abdallah Tawfic, Cairo

I live in a country that lives the dream of conquering the desert and building new cities. Cairo is the second largest city in Africa with a booming population crossing 23 million over an area representing less than 5 percent of the whole country’s land. New ideas such as green roofs could add a decent amount to Cairo’s green spaces, given the huge amount of abundant flat concrete roofs. The idea has triggered the government’s attention in the form of two national campaigns.

Vegetation is the Future of Architecture
Gary Grant, London

There is now a huge and growing body of evidence that green infrastructure or green-blue infrastructure (soil, vegetation, and water) that provides the setting for our cities, provides us with a range of benefits (also described as ecosystem services), including reduction in flooding, purification of air and water, summer shade and cooling, better health and wellbeing, places to relax and mingle, as well as food and habitat for wildlife. Having begun to appreciate the benefits of putting green infrastructure onto buildings, architects, engineers, horticulturalists, and others have developed techniques to do this.

Imagining Future Cities in an Age of Ecological Change
Ursula Heise, Los Angeles

Floating cities. Flying cities. Domed cities. Drowned cities. Cities that flip over once a day to expose different populations to sunlight. Cities underground, in the oceans, or in orbit. Cities on moons, asteroids, or other planets. Cities of memory, of surveillance, or of violence.

Speculative fiction in the twentieth and twenty-first centuries has offered an enormous range of urban visions of the future, many of them dystopian, a few utopian, and quite a few somewhere in between.

For good reason: Cities have taken on a new centrality for human futures.

Time of the Poppies
Andreas Weber, Berlin

What is the essence of a city? What is the kernel of urban civilisation, which, as we know, is engulfing the planet? Urban life is spreading from a minority’s lifestyle to be the predominant fate of human and increasingly nonhuman beings. As I thought in a first glimpse, being stopped at that glowing traffic island, the essence of a city is a constant immersion of everything and everybody in human affairs.

The Shape of Water, the Sight of Air, and Our Emergence from Covid
Lucie Lederhendler, Brandon

I have been working on a mind map of emptiness, inspired by an old Wiccan meditation practice of gazing into a bowl of water and trying to see the middle of the water. In the middle of a large sheet of newsprint, I encircled the word “emptiness” and build outwards with interlocking shapes. This is the experiment design phase of my practice, so it is yet to be seen if it will become a work of art, writing, or exhibition.

When commuters once again gather at the metro station, they will join the sound of fauna and the fragrance of flora in an atmosphere of palpable connections. Perhaps we may insist on sharing that space with a revived sense of the need for a radical redistribution of resources and care.

Cities in Imagination
David Maddox, New York

We can imagine sustainable cities—ones that can persist in energy, food, and ecological balance—that are nevertheless brittle, socially or infrastructurally, to shocks and major perturbations. That is, they are not resilient. Such cities are not truly sustainable, of course—because they will be crushed by major perturbations they’re not in it for the long term—but their lack of sustainability is for reasons beyond the usually definitions of energy and food systems. So, here’s my vision of the just city. It’s green. It’s full of nature’s benefits, accessible to all. It is resilient, and sustainable, and livable, and just.

Highlights from The Nature of Cities 2020

Many voices. Greener cities. Better cities.

Today’s post celebrates some of the highlights from TNOC writing in 2020. These contributions—originating around the world—were one or more of widely read, offering novel points of view, and/or somehow disruptive in a useful way. All 1000+ TNOC essays and roundtables are worthwhile reads, of course, but what follows will give you a taste of 2020’s key and diverse content. Which is not entirely about Covid, although it could have been.

Check out highlights from previous years: 2019,  2018, 20172016, 2015, 2014, 2013, 2012.
2020 was difficult. Heartbreaking. I am sure everyone reading this has been battered by COVID. We all have lost people. So much of what we love about cities—performing arts, restaurants, diverse communities, employment…life—has been gutted. I hear us talk about nature coming back, and the value of parks, and yet…and yet there has been so much human devastation. Now that we have seen how our cities around the world truly function at their most vulnerable, what possible excuse do we now have to not emerge solely committed to fixing it? Maybe in searching for a new post-Covid “normal”, we need to act on the idea that the old normal was a big part of the problem.

But COVID is not the only story of 2020. In many ways the “normal” work of the TNOC communities gains some new impulse.

Onward. In essays, roundtables, and reviews we continue to seek the frontiers of thought found at the boundaries of urban ecology, community, design, planning, and art. The Nature of Cities advanced in a number of ways in 2020. The number of contributors has grown to over 900, and we published 100+ long-form essays, reviews, exhibits, and global roundtables. Importantly, we’ve attracted more and more readers: over two million people have visited TNOC. And in 2020 we had readers from 3,500+ cities in 150+ countries.

Thank you. We hope to see you again in 2021.

Covid has upended all the normal routines in our lives and work. How do you imagine you might be changed by it, both professionally, but also personally as you negotiate a new post-virus “normal”?

COVID. We are all confined to our homes—if we are lucky (more on that later). Which is something, since most of us are “outdoor types”, “people types”. Can we find meaning, motivation, and renewed spirit for action in this contemplative but deeply strange time? We find ourselves wondering, doubting, planning our next steps or perhaps second-guessing our last ones.

How do we pick up the pieces? What pieces are even still available to us? Which pieces should we cast aside, and leave on the ash heap? There are a few key threads in this collection of 58 people from 24 countries, and many hopeful responses.

Now that we have seen how our cities around the world truly function at their most vulnerable, what possible excuse do we now have to not emerge solely committed to fixing it? Maybe in searching for a new post-Covid “normal”, we need to act on the idea that the old normal was a big part of the problem.

We Need an Ethical Code for Water

After a workshop held at “The Nature of Cities Summit” (Paris 2019), a group of TNOC contributors committed to meeting regularly in order to establish an ethical basis for water use and management.

This document is a preliminary draft of our understandings, hopefully a basis for many conversations and policy discussions as more and more stakeholders address the principles laid out. The document also represents a simple guide for ethical actions with regard to water.

Art and Exhibits

During COVID-19, The Urban Ecological Arts Forum at The Nature of Cities, sometimes known as FRIEC, is bringing to life virtual exhibition spaces, highlighting current exhibitions on urban ecological themes that would otherwise be impossible to experience due to the closure of cultural facilities. We did five such exhibits in 2020. All are remarkable. Here are two.

Beaver Village

Who Takes Care of New York?

This exhibit draws upon the USDA Forest Service’s Stewardship Mapping and Assessment Project, which is a dataset of thousands of civic stewardship groups’ organizational capacity, geographic territories, and social networks. The show features 4 artists whose work aligns with the themes of community-based stewardship, civic engagement, and social infrastructure. Through photography, drawing, book arts, and performance, these artists reflect upon, amplify, and interpret the work of stewards and the landscapes and neighborhoods with which they work.

Hidden Flows — photographers uncover the invisible flows in African cities

The exhibition emerged out of a need to enrich current conversations about resources, infrastructure and services in African cities. The images and stories shared here portray the diverse ways in which we resource our cities, the unique cultures that emerge because of this, and the value that private actors contribute to our societies. The dialogues which accompany this exhibition seek to invite more perspectives into the conversation on urban resources, to connect quantitative and qualitative understanding of our cities, champion the value of creative expression in meaning making, and reflect on internal and external portrayals of African cities.

Stories of the nature of cities 1/2 hour

We launched “Stories of the Nature of Cities 1/2 Hour” in 2020, a monthly series of readings from TNOC’s collection of very short fiction about future cities. Each episode is 30 minutes and features two readings and then a conversation between the authors and an urban practitioner. You can catch them live the first Thursday each month, or you can watch and listen to the recordings.

The stories are drawn from the book of flash fiction (less than 1000 words) on future cities TNOC and partners created, called “A Flash of Silver Green”.

Cities Are Not to Blame for the Spread of COVID-19—nor Is the Demise of Cities an Appropriate Response

The Place of Nature in Cities: Taking Inspiration from Singapore

Re-envisioning Cities Through Bottom Up Neighbourhood Planning, Not Top Down Master Planning
PK Das, Mumbai

A sustainable ecology of cities is possible when we successfully combine environmental and socio-economic dimensions equally in our plans and actions. In fact, it is the extent of their integration and inclusion that should form a criterion by which we evaluate our success.

Gifting a White Elephant, In the Form of Green Infrastructure
Amanda Phillips de Lucas, Baltimore

White Elephant: 2. figurative. A burdensome or costly objective, enterprise, or possession, esp. one that appears magnificent; a financial liability. The history of green infrastructure implementation in Baltimore shows that what communities care about and care for has been co-opted into practices of maintenance for others. The current state of many facilities demonstrates this approach is not effective. It is time to experiment with a new way forward.

Renewable Rikers as a Blueprint for a Sustainable City
Rebecca Bratspies, New York City

On 29 January 2019, New York City Council held a hearing on a trio of bills collectively known as “Renewable Rikers”. Rikers is currently home to the most infamous prison in New York City—the Rikers Island correctional facility an island penal colony with one lone bridge connecting it to the rest of the City. Renewable Rikers is an opportunity to end an old, but ongoing wrong. For too long, New York City has disproportionately sited its polluting infrastructure in low-income communities and communities of color.

This work is long and has not been easy. Sometimes we are discouraged by lack of resources and understanding, by violence, by increases in poverty, by politics, by the realities of Colombia. But our hope is still alive, and we remain motivated to contribute our little piece of peace to the life of this beloved corner of the hills of Bogota.

Arriving at each new city, the traveler finds again a past of his that he did not know he had. — Italo Calvino

When we read unexpected and remarkable things, we smile, even laugh out loud, and think: yes, this makes sense; and I didn’t think of it before now. In this spirit, let us celebrate some of the highlights from TNOC writing in 2021. These contributions from around the world were some combination of widely read, especially innovative, and/or disruptive in a useful way.

TNOC Festival offers us the ability to truly connect local place and ideas on a global scale for a much broader perspective and participation than any one physical meeting in any one city could ever have achieved.

Key to us is lowering barriers to participation. Barriers of all sorts: the costs of travel and lost time at work, language, registration costs (are are very inexpensive and often free). And the the program is largely crowd sources to reflect the kinds of conversations you want to have.

Plus, we have a remarkable format and engagement platform. Likely something you have never experienced in a professional meeting.

This year, TNOC festival will take place 29-31 March 2022. Registration opens 1 February, along with a full program announcement. Join us.

Beyond Equity: What does an anti-racist urban ecology look like?

There has been a growing belief in the need for “equity” in how we build urban environments. The inequities have long been clear, but remain largely unsolved in environmental justice: both environmental “bads” (e.g. pollution) and “goods” (parks, food, ecosystem services of various kinds, livability) tend to be inequitably distributed. Such problems exist around the world, from New York to Mumbai, from Brussels to Rio de Janeiro to Lagos.

There is a logical resonance of this idea to a wide variety of identities, histories, prejudices, and processes that systematically exclude and discriminate among people, including (but sadly not limited to) colonialism, social caste, gender, sexual orientation, religion, ethnicity, and indigeneity.

So, let us try to imagine approaches beyond the mere basics of equity. What would an anti-racist (or de-colonial or anti-caste, and so on) approach to “urban ecologies” be? How would it be accomplished? Is it an approach that would create progress? How would it integrate social and ecological pattern and process? How would we as professionals and concerned urban residents engage with it?

We must be fiercely honest with ourselves by shining lights into the patterns and limitations — yes, the stubborn prejudices — of our own professions. What can we do as individuals? How can we nudge our disciplines — ecology, or planning, or architecture, or policymaking, or educations, or civil society, or whatever — in better directions?

How can nature-based solutions (NBS) provide the basis for a nature-based economy?

Nature-based solutions provide an overarching framework embracing concepts and methodologies such as biodiversity net-gain, ecosystem-based adaptation, mitigation, environmental disaster risk reduction, green infrastructure and natural climate solutions to name a few. While much focus to date has been on the environmental or social benefits of nature-based solutions, less attention has been paid to their economic potential and their role in contributing towards more sustainable and just societies.

Indeed, modern economies are not generally build around nature and nature-based solutions — other than extracting from nature. The dire predictions of our climate changed future, now in many way already our present, tell us that this must change. Business as usual is not a prescription for human survival.

Art and Exhibits

As COVID-19 began, The Urban Ecological Arts Forum at The Nature of Cities, sometimes known as FRIEC, started bringing to life virtual exhibition spaces, highlighting current exhibitions on urban ecological themes that would otherwise be impossible to experience due to the closure of cultural facilities. We have expanded this idea of a regular series or “installations” that traverse the shared frontiers of art, science, and practice.

The State We’re in Water: Constructing a Sense of Place in the Hydrosphere

In this exhibit, science and art are used side-by-side, allowing us to peer deeply into both sides of this human dichotomy through our relationships with water. After multiple years of interdisciplinary research and production, artists Robin Lasser and Marguerite Perret find that we certainly have some work to do in order to live up to our potential as an earth-bound species. This experience is a curated tour of three selected galleries from what is an extremely far-reaching exhibition produced by Lasser and Perret. The selected works here relate intimately to our human relationships with water in cities.

City in a Wild Garden: Stories of the Nature of Cities, Vol. 2

This is our second volume of short fiction about current and future cities. We wanted to explore how to imagine cities. We asked authors to be inspired by an imagining, an evocative phrase: “City in a wild garden.” In this volume, there are stories of transformation, loss, and despair, and also stories of great beauty and hope, with nature and people that emerge from trials, in which people and the wild have merged in fundamental ways. Forty-nine stories from 20 countries are in this book, including the six that we judged to be “prize-winners,” by authors from the United States, India, and Brazil.

SPROUT: An eco-urban poetry journal

SPROUT is an eco-urban poetry journal that curates space for trans- and multi-disciplinary collaborations between poets, researchers, and citizens with a focus on geographical diversity, polyvocality, and translation. For the first volume, in inviting new work to reflect expansively about space, the contributors took up the call to carve out space(s) for themselves. The collected product reflects a multitude of poetic practices. What brings them all together is a particular attentiveness to the liminal, the in-between, the beingness of being-in-space, and acts of seeing out (or, indeed in) wards, into space.

Vegetation is the Future of Architecture
Gary Grant, London

Having begun to appreciate the benefits of putting green infrastructure onto buildings, architects, engineers, horticulturalists, and others have developed techniques to make it real. Cities and buildings, in particular, are designed and maintained in ways where vegetation is omitted, removed, or simplified so that the benefits of having vegetation close by are limited or lost.

When “Good Commons” Create “Bad Commons”
Praneeta Mudaliar, Ithaca

We need to reimagine the institutional landscape of urban disputed commons governance to accommodate diverse goals and management practices that simultaneously produce good and bad commons.

On one hand, practices of good commoning produce bad commons. On the other hand, if disputes were to be resolved, the land would likely be privatized, halting the practices of good commoning.

Two Reflections: Thinking About Blackness, Ecology, and Architecture in the United States
Steward Pickett and Brian McGrath, New York

The history of building and space is richer than we usually think. So are the visions of a less racist future, motivated in part by many Black voices and gazes. Reconstruction in America worked briefly in the past, ending not in failure but in its active repression. Black ecologists and architects teach us not to be limited by one’s discipline and, in the words of the creators of the MoMA exhibit, to enact a practice of refusal.

Auto-rewilding Birdlife Along the Bath River Line
Lincoln Garland, Bath

By shining a light on the many urban avian dramas along the Bath River Line, I reveal the amazing behavioral adaptations of birds to our highly human-modified world. Moreover, I suggest that there are as many opportunities for city-dwellers to connect with fabulous wildlife and, in particular, birdlife, as there are for their rural counterparts.

Greening the Recovery? A Proposal for Forwarding Urban Transitions as a Recovery Agenda Towards Resilience
Niki Frantzeskaki, Melbourne

Putting nature at the heart of recovery thinking is an argument we read and hear since the beginning of the COVID-19 pandemic. Will we act on this argument? If not, it is just a new greenwash. Collaboration is catalytic for co-design and co-create nature-based solutions with social innovators and citizens including Indigenous communities and not-easy-to-reach groups to make recovery just, equitable, and inclusive.

Financing Greener Cities for the Future We Want
Ingrid Coetzee, Capetown. Elizabeth Chouraki, Paris 

The world is rapidly urbanizing, putting our natural resources under increasing pressure to meet demands for infrastructure, land, water, food, and other crucial needs. Building greener cities for a more sustainable future is possible, but requires action and redirecting investment by both the public and private sectors. To take the conversation about investment for redesigning cities where nature is part of the solution and results in no net harm to biodiversity, ICLEI organized and hosted a virtual seed session at TNOC Festival 2021. In French and English.

Tree Inequality Is Worse in the Suburbs
Rob McDonald, Washington, DCA brick building. A suburban yard.

We urge urban forestry advocates to not forget about the suburbs when planning tree planting actions to increase tree equality. Suburban neighborhoods that are low-income or with many people of color may be important places to focus efforts to increase tree canopy if we are to aim for a city in which all households have adequate nature nearby. Urban trees and their canopy cover provide many benefits for urban residents, reducing air pollutant concentrations, mitigating stormwater runoff, maintaining water quality, encouraging physical recreation, and improving mental health.

Since 13 March 2020, our team of social science researchers has been keeping a collective journal of our experiences of our New York City neighborhoods, public green spaces, and environmental stewardship during COVID-19. Overall, we found that all stewards—civic and public—responded to the novel conditions of the pandemic. Some adapted more nimbly than others, but the question remains: whose practices will most fundamentally be transformed and how in order to help enable more resilient and inclusive cities and greenspaces?

Is Cali the City with the Most Birds in the World?
Rubén Darío Palacio, Durham

Cali has 562 species of birds; more than all of Europe. Key reasons are that its boundary spans an elevational range between 950m and 4,100m, going through wetlands, grasslands, and dry forests, climbing up to cloud forests and the high Andes. The city lies at the crossroads of three major biogeographic regions. And Cali also has a remarkable number of protected areas. Cities have a long list of duties to become global environmental leaders, and I contend that a humble bird list is a great way to start.

Knowledge Systems for Urban Renewal
Christopher Ives, Nottingham

There is a wealth of scientific evidence showing that urbanisation has been, and continues to be, a global driver of habitat loss and ecological transformation, but that cities can also be places of rich biodiversity. Knowledge production can be elitist and exclusionary, with important voices omitted. Further, the knowledge produced by current knowledge systems is often disconnected from action. We need to diversify the kinds of knowledge available to support NBS.

Amid the coronavirus outbreak, edible gardens have seemed to become an even more critical practice for cities experiencing lockdown, as food supply chains are upended and an edible garden plot close-by residents could enhance food security and mental health. It is also an important time for urban planning to rethink the human-nature relationship while designing the legal mechanisms for not only land use zoning, but also a possibility for nearby residents to suggest a rezoning.

Our Privilege as Choice
Hita Unnikrishnan, Bangalore

Urban planning has historically been iniquitous and geared towards improving the lifestyles of the already privileged. During our long term research conducted into the socio-political and ecological changes driving the loss of lakes within Bengaluru—capital of the south Indian state of Karnataka—we found that certain groups of people have been historically marginalized and continue to remain vulnerable to pressures posed by ongoing urban change.

Highlights from The Nature of Cities 2022

Many voices. Greener cities. Better cities.
I go to nature every day for inspiration in the day’s work. — Frank Lloyd Wright

Cities should be collaborative creations, no? Various professions, ways of knowing, modes of action, governments, and the people that live there, work together (we hope) to build their city from their shared and often contested values. And we need to find greener routes to built cities for them to be sustainable. This mixing of different ways of knowing into shared visions toward cities that are better for both people and nature is the core spirit of TNOC. In this spirit, let us celebrate some of the highlights from TNOC writing in 2022. These contributions from around the world were some combination of widely read, especially innovative, and/or disruptive in a useful way. What follows will give you a sampling of 2022’s remarkable content.

In 2022, TNOC continued to lean into the arts — and specifically art-science collaboration — as a productive route to innovation. Such art-centered projects are reflected in these highlights. We also presented our third major event, The Nature of Cities Festival 2022. We continue all of these efforts.

Check out highlights from all ten years at TNOC, 2012 to 2021. 
In addition to our projects,  we have grown to over 1,000 contributors. We welcome new collaborators and contributors. If you would like to join us in a project, as a support, or as a contributors, visit here.

In our writing we continue to seek the frontiers of thought found at the fizzy boundaries of urban ecology, community, design, planning, infrastructure, and art. Onward and upward, let us hope.

Thank you. We hope to see you again in 2023.

Artists and scientists that co-create regenerative projects in cities? Yes, please. But how?

What if scientists and artists worked together to co-create knowledge? This could be in active co-production, or even just in sharing ideas about shared objects of inquiry. This kind of sharing happens relatively rarely — most people in art and science tend to work squarely within their disciplines — but more and more of us are trying to create useful spaces in which artists and scientists interact. As land care and ecosystem regeneration become increasingly paramount, more artists and scientists, and practitioners are dedicating their efforts to participating in such practices together. We are one, with multiple shapes. In the same logic, collaboration between knowledge bases is crucial to addressing problems that haven’t been solved by monolithic thinking, and may have been created by it.

Three pink tulip flowers attached to bulbs and roots on a white background, Sixteen Miles Out, unsplash.comCan we enable better decision-making when it comes to urban plant selection and preparation? Does urban ecology and the horticulture industry need to be better engaged with each other?

As urban and environmental practitioners and change-makers, whether in the public, private or NGO sectors, we work to respond to the global imperative to bring more nature into our cities, with a seemingly clear understanding of the science that underpins the urgency of the current moment. We know full well that nature provides many benefits which sustain our increasingly urban lives. We also know that this nature is diminishing at unprecedented rates and needs to be protected, conserved, and even restored as a matter of priority. Acknowledging the need to act now is an easy message to promote, and at the strategic planning level, awareness, and advocacy of the need for action are at an all-time high. But do we know what this action entails at a practical level?

Politicians discussing climate change. Montreal, Canada (2015). Isaac Cordal

We have had trouble getting people’s attention about climate change. Some climate activists glued themself to a van Gogh painting (and others). Is this helpful?

What will spur action? Recently some climate activists have taken to gluing themselves to or throwing food on famous paintings. There have been quite a few examples. Several activists were recently fined. (Apparently, no paintings have been seriously damaged yet.) “The adults aren’t listening”, say many young people, and it is hard to say they are wrong.

Are such shock tactics useful? Can they change their opinion (in either direction)? Are they directed at the wrong targets? This is a prompt that asks us to reflect on the value of contentious and activist dialogue at intersection of art, science, ecology, activism, cities, and public opinion. A common theme among many of the responses included here — across the YESs, MAYBE, and NOs — is a deep exasperation at our failure to move climate action forward. One thread is that such activism aims at the wrong target. Another is that, well, it may be absurd, but at least it gets people talking about climate change.

Nature for All: How can we uproot structural inequity in the provision of nature and its benefits to people?

As societies and individuals, we only overcome such a system of oppression by recognizing it and dismantling it. Dismantling might require a kind of reverse engineering. Is that too slow? If so, is the approach to figure out where the wrenches are best thrown into the gears? Making us all look away from the larger machinery of racism is one of the racialized machine’s most insidious strategies for its own perverse resilience.

Of course, such oppressive systems do operate all over. The gigantic social-environmental system of racism has dimensions of colonialism at global and within-nation scales. In traditions where race doesn’t provide the operative hierarchy, colorism often stands in. Oppression has other dimensions too: religion and sect, gender, class, migrant status, and access to training and education, among others. Research on such things as the global extent of segregation, or the deep, lasting legacies of colonialism in both the “periphery” and the “mother country,” demonstrate the virtually universal importance of a structurally inequitable system that affects access to nature’s benefits.

 

Art and Exhibits

One of the things I learned [as the first artist-in-residence at NASA] was that artists and scientists have a lot more in common than you think because scientists don’t know what they are looking for either. — Laurie Anderson

In recent years TNOC has greatly expanded out investment in and comment to art and art-science-practice collaboration. This has taken the broad forms of poetry, fiction, exhibits, comics, graffiti, and residences of artists working with science teams. In every expression, we design to mix voices from artists, scientists, and practitioners together in the joined conversations about the issues we face. Here are a few examples.

Urban Field Station Collaborative Arts Program

The Urban Field Station Collaborative Arts Program is a virtual, community-centered artist residency brought to you by the USDA Forest Service, The Nature of Cities, and local partners. Selected artists engage with land managers and researchers to better understand, represent, and communicate about urban social-ecological systems through works of art and imagination. The program’s mission is to promote understanding of and engagement with urban ecology through art. The Urban Field Station Network understands cities as social-ecological systems, and this year’s call for artists focuses on the theme of connectivity.

Shade in the City: Rising Heat Inequity in a Sunburnt Era

To tackle the issue of urban heat, a group of 18 artists and activists in Los Angeles’ vibrant Highland Park neighborhood raised awareness of shade as an equity issue in an outdoor public art installation called Shade in LA | Rising Heat Inequity In A Sunburnt City.

In a warming world, shade equity is an issue that disproportionately affects low-income and working-class communities, people of color, and communities in developing nations who are more likely to work outdoors, rely on public transportation, and live in denser neighborhoods with a lack of trees and shade.

Nikki Lindt—The Underground Sound Project

The Underground Sound Project is a collection of underground sound recordings made by artist Nikki Lindt over the course of the past year in the five boroughs of NYC and in rural Cherry Valley, NY. The recordings are made by placing microphones underground, underwater and even inside trees.

The Soundwalk is experienced along the trail in Prospect Park, NY. Along the path you will encounter features, such as a stream, old growth tree, soils, wildflowers, and many more. Via a sign with a QR code at designated locations along the walk, you will be able to experience the corresponding subsurface sounds. The soundwalk can also be experienced remotely with headphones.

Sprout Eco-Poetry Journal: Issue 2

As a way of looking at the intersections between people, nature, and cities, for SPROUT’s second issue we invited poets to think about the edges of the eco-urban. Specifically, we were interested in how poets interpreted what constitutes the edge (or edges) of city life with its marginalia, liminality, and transitional spaces. The contributions that make up the issue offer us a window through which to view the edge(s) as places of (re)invention and (dis)comfort—where the edge can synchro- nously signal endings and beginnings. In the in-between, the edge offers up a fresh, creative space—a space where things overlap and push us to consider new ways of working, seeing, and being in the world.

Developing a Successful Climate Action Plan for Mumbai
Samarth Das, Mumbai

With over 140 km of coastline and 480 sq.km land area, Mumbai is one of the most vulnerable cities to climate change-induced hazards such as sea-level rise, storm surge, and urban flooding amongst many others. With significant climate change impacts already affecting us, we need to go one step further than to simply suggest methods of mitigation and focus more on radical adaptation and change the way we look at development in our cities.

Governments and communities around the world are embracing Nature-based Solutions (NbS) as a major climate adaptation strategy. In order to address the challenges of the 21st century, we cannot rely on 20th-century managerial paradigms and must embrace new multi-scalar governance arrangements centering beneficial human relations with nature and reduce our dependence on technological extractivism.

Brian McGrath, New York. Vineet Diwadkar, Bangkok

Video data gathering captured the spatial and temporal distribution pattern — the flux/flow — of the ecology of small lanes in Bangkok. We present this distributive architectural system of local urban ecological data gathering as fundamental in collectively addressing the twin crises of social justice and climate change. It suggests that we should stop seeing cities in terms of centers and peripheries, a residual concept of colonial metropolitanism, but as patchy distributive ecological systems, where every point in the system has value.

Historically, thopes have been an integral part of the rural landscape, planted with fruit and timber yielding trees, and cared for by the local community. But, in recent times, there have been transformations to these thopes, especially in the peri-urban interface of cities such as Bengaluru, the capital of Karnataka. Our story is about one such thope that transformed from a grove of towering mango (Mangifera indica) and jamun (Szyzygium cumini) into a landscaped park with lawns and ornamental plants.

Going forward, Section 19 offers important guidance to New York’s legislature as it debates a wide range of new legislation across a host of topics including eliminating structural racism, criminal justice reform, public education, transportation and energy needs, housing and development, and climate change.

Better Rankings for Better Cities: The Limitations and Prospects of City Rankings
Devansh Jain & Perrine Hamel, Singapore

As urban practitioners, it’s important to understand the significance of these city rankings and indices, how they may or may not be useful, and be clear and mindful of their limitations. In this post, we present the preliminary findings from our research on city rankings and indices, exploring who are the users of city rankings, and how they use rankings in practice. We also identify the limitations of city rankings and propose future prospects and recommendations.

They Didn’t Pave “Paradise”, They Ploughed It
Lincoln Garland, Bath

While urbanization certainly has had many very negative impacts on the natural world, is the hostility that environmentalists and the wider public hold for it justified, or is there a much more important factor driving biodiversity loss? The impact of urbanization needs to be kept in perspective compared with the much greater threat to biodiversity coming from our unsustainable global food system. If we were to dismantle major urban centers and spread their populations over the surrounding countryside, far more pastoral paradise would be consumed and carbon footprint per capita would rise dramatically.

The goal is to mainstream Nature-based Solutions, by widening public acceptance and making it the standard and default practice of urban design. What will it take to get there?

There has been great enthusiasm among NbS professionals for “mainstreaming” NbS into urban practice. We generally mean one of two things when we say mainstreaming NbS: (1) making NbS more widely known in the general public (like, say, “climate change” is…maybe); and (2) making NbS the default or common practice among urban professionals. The two are perhaps related, but the audiences for such social change are not exactly the same. Plus, NbS professionals are often a little vague about which element of “mainstreaming” they are talking about. What are the wicked problems for which we need “solutions”? They are found embedded in both social and environmental challenges, which are difficult to disentangle. Maybe they should remain entangled, so we can seek and find complex solutions.

How can we create and maintain communities that people need and deserve; cities that are better for both nature and all people; that are beautiful, liveable, healthy, sustainable, resilient, and just? The New European Bauhaus (NEB) aims to “co-create beautiful, sustainable and inclusive solutions for neighbourhoods across the EU”[1] that “deliver on Green Deal objectives”. The Horizon Europe Work Plan for 2023-24 emphasizes mainstreaming biodiversity and Nature-based Solutions (NbS) in society and the economy.[2] Integrating transdisciplinary knowledge-building along with creatively co-productive engagement and implementation at local scales propels the core aims of both NEB and Horizon Europe. Weaving together art, science, land management, and public perspectives through transdisciplinarity — especially when it is grounded in place — strengthens stewardship and produces new knowledge that we would not otherwise create.

Story. Telling. If you had a project from science or practice and wanted to make it a better story — one that could reach into new audiences — what would you do?

A piece of paper with writing on it
Figure 1. ‘Once upon a time …’

There are five key elements to just about every story: plot, setting, characters, point of view, and conflict (that is, a tension that presents itself). We typically use all of these when we recount a story or event to our family and friends, at least subconsciously. But we don’t use such techniques in science. Why not? What if we explored a rich storytelling approach to knowledge from science and practice? Human-scale stories. Stories with emotional resonance. Dare I say it? Even entertaining stories. Stories that connect to people who perhaps are not “experts” in whatever field, but nevertheless have a real stake in the decisions and outcomes, and so deserve to have access to the knowledge that supports (or does not) decision making.

Visual storytelling: Can comics help us advance solutions to our social and environmental challenges? Yes

Can we tell better and more engaging stories about our environmental and social challenges? Can we widen the circle of people who read such stories and take action? Can we use them for education and engagement? Can they create good and entertaining and useful stories? Yes, we can. Although the comics landscape is dominated by superheroes doing classic superhero things, there is a growing movement of comics that have environmental and social justice aims. Comics offer a unique and effective platform for addressing social and environmental challenges through storytelling. The combination of visuals and narratives in comics provides a dynamic and engaging medium to convey complex issues in a compelling manner.

Art and Exhibits

In recent years TNOC has greatly expanded our investment in and comment to art and art-science-practice collaboration. This has taken the broad forms of poetry, fiction, exhibits, comics, graffiti, and residences of artists working with science teams. In every expression, we design to mix voices from artists, scientists, and practitioners together in the joined conversations about the issues we face. Here are a few examples.

NBS Comics: Nature to Save the World

TNOC’s latest project in collaboration with NetworkNaturePlus, funded by the European Commission, Nature-based Solutions (NBS) Comics empowers comic creators to combine science and storytelling, re-imagining how people and nature might thrive together. We invite comic creators from all over the world — using any comic style, various approaches to storytelling, and many languages — to imagine comics about nature and her benefits. One of our hopes for this series is to tell good stories about nature that are both intelligent, entertaining, and change-making; from new voices; stories that reach more people. We want to create dialogue and raise awareness about nature and what essential role it plays in our daily lives.

SPROUT: An Eco- urban Poetry Journal: Issue 3

For SPROUT’s third issue, the editors were inspired by The Nature of Cities’ (TNOC) recent art exhibition, Shade, and invited contributors to draw on the exhibition’s virtual installation as a conceptual springboard to contemplate the theme of shade through a poetic lens. We asked poets to reflect on the role shade plays in the built environment, particularly focusing on shade equity—i.e., how shade can make more inclusive spaces in the city, or, conversely, how the lack thereof can create inhospitable, hostile spaces. We were interested in soliciting work that considered shade from ecological, architectural, and environmental justice points of view.

LES SAVOIRS VIVENT DANS LA TERRE: KNOWLEDGE IS IN THE LAND
a story by Carmen Bouyer

We invite you to embark on an artistic journey framed like a short tale, narrated by the artist Carmen Bouyer and made possible by The Nature of Cities team. This story bridges the urban and the rural in a quest to create art forms that connect us with the larger landscape. The story is an invitation to imagine our own very personal ways to listen and connect with the places we inhabit. Here we will follow the artist’s story of coming home to the Paris region in France after years of living abroad in cities. As many urbanites in Western European cities, Carmen had the feeling that the cultures of relating with the land there were lost since a long time.

Composing an Entropic Symphony from the Sounds of Plants About to Be Displaced
Lucie Lederhendler, Brandon.

A picture of a woman with headphones and a laptop sitting amongst large, leafy plants

Helga Jakobson built a synthesizer system that reads the bioelectric impulse of the plants, and would clip alligator clips onto their leaves. Then the system reads the bioelectric impulse of the plant. More than figuring out what the plants sound like, Helga had to figure out who was singing. In just three months, she collected over 500 hours of plant song and, for the past five years, she has been composing these sounds into a symphony. Information on the final product, Entropic Symphony, can be found on her website.

The Dilemma of Water Scarcity and Ecological Stewardship in Ghana
Ibrahim Wallee, Accra

A picture of a young girl drinking water from her cupped hands

The phenomenon of water scarcity and access to safe drinking water as a life-saving resource is a significant concern for human survival and should be recognized as such. Though not sustainable, the increased production and consumption of sachet water as a primary source of drinking water is an inescapable reality in rural and urban communities of Ghana today, irrespective of households’ differential experiences with accessing this product.

Nature-based Solutions Are Gaining Momentum in Brazilian Cities
Cecilia Herzog, Rio de Janeiro

A green land with a body of water

Although there is a clear move by many cities to recognize that nature is essential to enhance their resilience to face climate challenges, there is still a lack of a wider understanding of the immense benefits they may bring to urban environments. Climate crisis is impacting cities all over the world, and in Brazil, the outcomes are especially dramatic. Nature-based Solutions are gaining more relevance once the decision-makers understand their potential to build urban resilience and offer a better quality of life and well-being to their residents.

Green Urban Planning ― Along With the Idea of Objective Truth ― Is Losing the PR Fight
Rob McDonald, Basel

A picture of a tree-lined street with people and cars

We need to defend the general conception of objective facts and be willing to publicly mock those who, for political purposes, would reduce every discussion to a subjective balance of wills. Without science and the belief in the possibility of it guiding us to wiser choices, the environmental movement does not meaningfully exist. As an ecosystem service scientist, I have come to realize that the future of urban nature will not be determined by ecosystem service valuation and rational planning. It will be determined by whose vision of our urban home is more compelling.

The City: Binding an Unbound Space
Arvind Lakshmisha, Bangalore. Harini Nagendra, Bangalore

A picture of two people sitting overlooking a field with grass and cows

The way in which we imagine and understand cities and define their boundaries influences how we think about governing the city, and planning adaptation and resilience strategies, which become increasingly important in the era of the climate crisis. Thus, viewing the city not as a bound entity based on economic definitions, but as a spatially fluid, dynamic distribution of people, processes, and activities connected with ecological systems, which then leads us to consider a city as an interconnected entity.

A New Tree Ethic: What If Trees Really Mattered?
Tim Beatley, Charlottesville

A picture of a large tree cut down with limbs and sawdust everywhere

Several weeks ago, I was startled when taking a typical morning walk to find that a large and majestic white oak tree had been cut down and lay in the front of a neighbor’s yard. It was a shocking and sad sight, a tree I had admired almost daily, reduced to a pile of sawed-up and lifeless segments on the ground. The benefits of trees are irrefutable, but they are not widely understood and don’t seem to change behavior much. This suggests we need other approaches to convince people trees really matter. There are several promising directions.

From a Buzzword to a Standard: Challenges in Mainstreaming Nature-based Solutions in Urban Planning in the Global South
Seema Mundoli, Bangalore. Abhiri Sanfui, Mumbai. Harini Nagendra, Bangalore.

A picture of a waterway full of trash with some vegetation on the banks

The question is how can we have a broader vision for our cities that can incorporate urban ecosystems into urban policy and planning? We need nature-based solutions to not be relegated to being a buzzword but be seen as a standard when it comes to planning cities. And we need applications in the Global South to be context-specific, not a copy-paste of what is done in the Global North. Perhaps the greatest challenge continues to be in building acceptance of nature-based solutions in urban planning and policy in the context of cities in the Global South.

Pinamar: A Garden City Looking Towards a Sustainable Future
Ana Faggi, Buenos Aires. Maria Samanta Anguiano, Pinamar.

In Argentina, as a long weekend arrives many people living in the metropolitan area of ​​Buenos Aires flee from the concrete and asphalt in search of Nature. There are many destination possibilities, but one that is undoubtedly a favorite is a garden city, 370 km south of Buenos Aires, which receives a million tourists in summer. Its name Pinamar — pine + sea — describes the cultural landscape where sea and forest meet, following the vision of an urban architect 70 years ago.

Ça Marche: Walking is Paramount to Human and Liveable Cities
Francois Mancebo, Paris

A picture of a crowd of people walking down a sidewalk along a street with buildings on both sides

Walking is not just about moving from one place to another. It also engages our senses. Such an experience forges affective bonds between pedestrians and their city by immersing them in urban ambiances. Ambiances are shared by any city inhabitant: they are a common treasure upon which urbanity takes root. The fact is that the walkability of a city is primordial to foster urbanity. It is long overdue to explicitly make walkability the cornerstone of urban design.

Caring in Public: A Framework for Social Infrastructure Visibility in Community-managed Open Space (Part 1)

A team of practitioners and researchers at the Central Park Conservancy Institute for Urban Parks, NeighborSpace, Borderless, and USDA Forest Service – Northern Research Station met from September to November 2021 to discuss research on social infrastructure and urban green spaces. There is not one magic framework that will tell the true story of community gardens, but it is crucial that we pay attention to the profound work occurring in community-managed garden spaces, and tell the story that does these efforts justice.

A Nonprofit Organization Creates Mini-forests in Public Schools in São Paulo Using the Miyawaki Method
Rafael Ribeiro, São Paulo

A picture of a hand scooping dirt from the ground

If you asked someone if they could imagine growing a forest from scratch, they would most likely say no. Yet, this is exactly what the non-profit organization formigas-de-embaúba is doing. Formigas-de-embaúba carries out environmental education programs to plant native mini-forests in public schools together with school communities. Students become active citizens, inspired to act and take small steps towards collective and transformative futures.

Urban Parks During Heat and Drought Conditions: A Case Study in Leipzig, Germany during the 2018 and 2019 Heat Periods
Roland Krämer, Leipzig. Nadja Kabisch, Hannover

Two maps of a city showing temperature through cool or warm coolers

Thanks to the cooling function of the vegetation, urban parks offer cool, pleasant places in cities during hot summer days. The results of the measurement campaigns impressively showed how important urban green spaces are for the provision of the cooling function as a regulating ecosystem service. In particular, urban parks still provide cooling under drought and heat conditions but also the vegetation in gardens or backyards reduce local air temperatures and contribute to heat mitigation.

Can Neighborhoods Provide Breeding Habitat for Interior-Forest Specialist Birds? Yes
Mark Hostetler, Gainesville. Natalie Pegg, Gainesville

A picture of a grey bird with a yellow belly perched on a branch

Interior-forest specialist birds are reported to primarily require large, undisturbed forest areas in which to breed (Archer et al. 2019). Why do these species need interior forest conditions? We do believe that with enough vegetation in a yard and neighborhood, these species will breed in or near your yard in cities located in the southeastern United States. Probably the limiting factor is the vertical height structure. Re-wild certain areas of your yard!

Highlights from The Nature of Cities in 2012

Many voices. Greener cities. Better cities.

Cities are ecological spaces.  But only relatively recently has this new vision of ecologically sophisticated cities gained momentum.  Today, in increasing numbers, scientists, designers, and practitioners create useful knowledge about the nature of cities through study and research that can inspire public debate and decision makers.  Thinkers imagine how to conceptualize urban nature; ecologists study its patterns and processes; sociologists demonstrate its importance to and for people; stewards devise ways to manage it; public health researchers reveal the relationships between healthy ecosystems and population health; designers and architects integrate human, green and blue with grey; and elected officials and city managers formulate and implement green policy.

And, importantly, more citizens are becoming more engaged in the conversation about urban nature – a conversation that directly relates to today’s critical debates about the livability, sustainability and resilience of human settlements. across the globe.

But let’s also be candid: there is a long way to go.  Thought-leading dialogue in urban nature needs to be broadened and democratized.  While there are a few dozen fantastic examples of cities leading the way on urban nature, there are about one million sub-national government entities in the world.  Only a fraction of these have the interest, not to mention the tools and resources, to integrate nature and green thinking into their urban planning.

We want this blog to be at least one small part of the expanded and enriched conversation about urban ecosystems that our increasingly urbanized world requires.  The Nature of Cities collective blog on cities as ecological spaces launched in June 2012, nearly six months ago.  Since then we’ve had over 27,000 views from over 800 cities and 80 countries.  And we have grown to 40 contributors from around the world.  A million thanks for your support and interest.

To celebrate the new year here are excerpts from some popular posts at The Nature of Cities in 2012.

Vacant Land in Cities Could Provide Important Social and Ecological Benefits

by Timon McPhearson
New York City

Walk through any major city and you’ll see vacant land.  These are the weed lots, garbage strewn undeveloped spaces, and high crime areas that most urban residents consider blights on the neighborhood.  In some cases, neighbors have organized to transform these spaces into community amenities such as shared garden spaces, but all too often these lots persist as unrecognized opportunities for urban improvement.  In densely populated cities with sometimes few opportunities for new park or green space development, small vacant lots could provide green relief, especially in low-income areas with reduced access to urban parkland.

And yet, few cities are taking advantage of these underutilized spaces to improve urban biodiversity and provide additional ecosystem services.  What’s even more surprising is the vast amount of urban land that is categorized as vacant.  Take New York City for example: in this urban metropolis there are 29,782 parcels designated by the city tax code as vacant within the city boundaries, not counting vacant land in the surrounding suburbs and exurbs.  This totals more than 7,300 acres of land that could be providing important social and ecological benefits for urban residents.  Read more…

Exploring the Nature Pyramid

by Tim Beatley
Charlottesville, Virginia

I have long been a believer in E.O. Wilson’s idea of biophilia; that we are hard-wired from evolution to need and want contact with nature. To have a healthy life, emotionally and physically, requires this contact.  The empirical evidence of this is overwhelming: exposure to nature lowers our blood pressure, lowers stress and alters mood in positive ways, enhances cognitive functioning, and in many ways makes us happy.  Exposure to nature is one of the key foundations of a meaningful life.

How much exposure to nature and outdoor natural environments is necessary, though, to ensure healthy child development and a healthy adult life?  We don't know for sure but it might be that we need to start examining what is necessary.  Are there such things as minimum daily requirements of nature?  And what do we make of the different ways we experience nature and the different types of nature that we experience? Is there a good way to begin to think about this?

Here at the University of Virginia (Charlottesville, VA USA), my colleague Tanya Denckla-Cobb has had a marvelous and indeed brilliant idea.  Why not employ a metaphor and tool similar to the nutrition pyramid that has for many years been touted by health professionals and nutritionists as a useful guide for the types and quantity of food we need to eat to be healthy.  Call it, as Tanya does, the Nature Pyramid, and we have something at once novel and attention-getting, but potentially very useful in helping to shape discussion about biophilic design and planning.

Neighborhoods and Urban Fractals – The Building Blocks of Sustainable Cities

by Paul Downton
Adelaide

Urbanisation is spreading across the face of the planet at an unprecedented rate.  Most of it is opportunistic; ad hoc development and shanty towns rather than master plans.  Virtually none of it, planned or otherwise, incorporates the elements of natural capital that are needed to create sustainable cities.  Every time a new piece of urban fabric is created, or an existing piece is patched up and reworked, it may add to the value of the real estate but subtracts from the ecological health of the urban area. As each conurbation grows it diminishes the biological wealth of its region.  Globally, the entire urban system trends towards becoming increasingly dysfunctional.

But what if it were different?  What if, every time we added to the weave of this great human construct, we constructed pieces of urbanism that not only provided good shelter for people but also increased biodiversity and enhanced the value of natural capital?

For some time I have been intrigued by the idea that one might be able to identify patterns in urban systems that could provide a systematic model for developing cities that can always and simultaneously incorporate the essential characteristics of ecologically sustainable urbanism – and that this might be applicable across the spectrum from eco-village to metropolis. Read more…

Putting Nature Back Into the Natural Beauty of Rio de Janeiro

by Pierre André-Martin
Rio de Janeiro

It is an irony that despite the magnificent natural beauty of Rio de Janeiro, the city itself is largely devoid of functioning nature.  It is now time for Rio to not only to host global events such as the World Cup and Olympics, but to host its primary nature, not outside the city, but in the middle of its streets, plazas and buildings.  This blog discusses a case study – the greening of the Carioca River watershed that emerges from Tijuca National Park – as an example of what we could accomplish for the good of all Cariocas (which is what residents of Rio are called).

The presence of nature is decreasing in the daily life of Rio due to the expansion of the impervious area at many scales, from street to district scale, architectural models of arid constructions and street tree plantings that are getting old.  Slowly the nature is being “expelled”, transforming the city in an hot and arid landscape.

Cities of Nature

by Eric Sanderson
New York City

Many entries in this collective blog about the nature of cities will focus your attention on the nature that remains in cities, defined in terms of those patches of semi-natural habitat, the green bits, which are found in all cities, and which can be encouraged or discouraged by human action.  Consider for example Celicia Herzog’s recent post delighting in the green landscapes in and around Rio de Janiero, connecting fragments of the famously-biodiverse Atlantic Forest in which Rio is emplaced.  Or consider Mike Houck’s paean to the nature nearby, and within, Portland, Oregon, where his organization seeks to make Pacific Northwest cities both livable and loveable for people and other critters.  Lovely pieces both, well worth your time.

I want to write about something related, but different, something which I think is both more encompassing and less well understood:  that is, the total nature of cities.  I want us to conceive of cities in their entirety as ecological places (more precisely, as ecological landscapes), where buildings, streets, boardwalks, sidewalks and parking lots, ball fields, basketball courts, fountains, and power plants, as well as the green bits, participate in a complex and evolving mosaic, where natural things happen.  By nature I mean the interactions of soil and rock, air and water, energy and life, that characterize our verdant planet, and by natural, I mean the qualities of everyone and everything that participates in the great congress of life on Earth, including you and me.  Those interactions and those qualities do not disappear when we build a city.  Rather they take on new, idiosyncratic forms, which contrast in many, ordinary and extraordinary ways, with the ecological mosaics that formerly filled the place where the city now stands.

It helps when thinking about the nature of cities to remember the nature that was there before the city, as in the Wildlife Conservation Society’s Mannahatta and Welikia Projects.

Let Us Champion “Biodiversinesque” Landscape Design for the 21st Century

by Maria Ignatieva
Uppsala, Sweden

I started my research as a landscape architect and urban ecologist in St. Petersburg, Russia. My home town is one of the biggest European cities and it is famous for numerous historical landscapes.  In that time (1990’s) investigation of urban biotopes was a novelty. Passion for the history of landscape architecture resulted in my concentration on biodiversity of historical parks and gardens.

With a dramatic turn in my life I had a chance to research UK, US and then New Zealand urban flora and vegetation.  One of the first striking surprises in the city of Christchurch, New Zealand, where I moved in 1997, was the similarity of urban floras.  I could easily identify almost 90% of plant material! Urban landscapes, traditions and way of life in New Zealand were so similar to “motherland” England and to general Anglo-American culture.  In this particular moment I felt myself a “global” person and started my research on unification of urban global landscapes and searching for alternative sustainable landscape design solutions.  I saw as my goal to use knowledge of landscape ecology processes and match them with landscape design practice.  Why the rest of the world so easily accepted British picturesque and gardenesque thinking even when this is not sustainable at all. How we landscape architects and environmentalists can convince ordinary citizens, as well as politicians and even our own professionals, to accept a new way of thinking — biodiversinesque — which gives a way and space to nature in our cities and not only “tidy” gardens with colourful flowers and lawns?

Discovering Urban Biodiversity

by Matt Palmer
New York City

The world is losing its biological diversity – or biodiversity – at an alarming rate.  The primary force driving this is habitat degradation.  When the places where animals, plants, fungi, and the myriad other organisms live are converted to other uses, conditions change and the prior residents often move on or die.  The two major causes of this habitat degradation, or the extreme of wholesale habitat loss, are agriculture and urbanization. And it is certainly true that converting forests or wetlands to corn fields or apartment buildings changes the land cover, vegetation, soils, hydrology, and other environmental factors in drastic ways. We all expect that many of the kinds of organisms found in those “natural” environments will be missing from the “manmade” environments.  And it stands to reason that, as more of the world is converted to “manmade” habitats, the space left for wild organisms diminishes and many are lost from the earth. [I’m using quotation marks around the words “natural” and “manmade” since these are rather gross oversimplifications of the range of human impacts – but that’s a topic for another day.]

While this narrative is true in the broad sense – there is abundant evidence of biodiversity loss resulting from human modification of the environment – it is too simple. It’s not just a case of cities (or farms, but this a blog about cities) replacing other kinds of ecosystems – there are some important nuances to this process.  Many elements of nature – the rocks, soils, sunlight and water, but also many organisms – persist even as a city grows up around them. The kinds of species and their abundances will change after urbanization, but some wild life will remain from the previous community.  Urban environments also encourage other kinds of organisms by providing habitats that were not present before.  And urban environments are sometimes recolonized by species that were originally lost.

Cities and Biodiversity: A Call for Up-Scaled Action

by Russell Galt
Cape Town

For all of us working in the field of “cities and biodiversity”, it is well worth reflecting on our achievements.  We can take personal satisfaction knowing that we contribute to a meaningful cause with tangible results. Every scientific paper, policy-brief and newsletter, every side event, meeting and presentation, every phone call, email and letter, even the brow-raising intensive travel regimes, collectively have contributed to a proliferation of projects, programmes, initiatives, tools and resources.  Collectively they are driving a positive movement – that is, the movement to bring nature back into urban areas, sensitize citizens to its importance, reduce ecological footprints, and secure ecosystem services.

…or are we failing?

Although many local governments are making commendable progress in managing biodiversity, the vast majority are visibly struggling with a lack of expertise, funds and capacity.  To bring this lagging peloton up to speed will require an up-scaling of technical support, an expansion of learning networks and a strengthening of performance incentives. Read more…

Architecture, Ecology and the Nature-Culture Continuum

by Brian McGrath
Newark, New Jersey

The Venetians built a remarkable city made up of close-knit island neighborhoods within a briny lagoon, centered on fresh ground water cisterns in the middle of sand filled public plazas called campi.  There are few cities where one feels so in touch with nature, in the stone of the buildings, the light bouncing off the remarkable reflective water of the lagoon and canals.  This is the special nature that envelops one’s body moving through that great city.

New Yorkers built a grid of reflective towers, which offer residents the pagan delight of “Manhattanhenge,” when the sun sets directly at the perspective endpoints of its 155 parallel cross-town streets.  On ordinary days, light bounces mysteriously from high towers blocks away into narrow airshafts of old-law tenements. Its grid slopes to two arms of the Hudson/Raritan estuary, and a bike riding tenement dweller knows how to escape the seasonal extreme heat or cold precisely according to a local knowledge of the glass-canyon microclimates.

Nature loving Bangkokians believe all things are alive, and offer food, flower garlands and incense to the ghosts that inhabit their city.  As part of their animist roots, nature is an invisible force only partly felt through sensations of hope, dread or fear. Buddhist practice places nature in a realm beyond form and sense, but manifest in temples designed as models of the cosmos.

What all three of these cities face is the uncharted future of dramatic shifts in climate.  Traveling between Venice, Bangkok and New York in 2011, I have seen the plight Venetians face with the high water of each high tide, a devastating flood in Bangkok that crippled a global industrial supply chain, and a ‘what if’ collective breath holding in New York as Hurricane Irene approached.  Clearly urbanists and naturalists need to immediately address the dual challenges of rapid urbanization and climate change from a diverse range of cultural practices globally.  In order to meet these pressing challenges we need to get beyond the ways we mentally separate nature and culture.

Souvlaki Coyote and Other Tales of Urban Wildlife

by Bob Sallinger
Portland, Oregon

Much of the fabulous writing on The Nature of Cities blog site to date has focused on integrating the built and natural environment, erasing, or at least softening the lines that separate the natural and the manmade.  I would like to shift focus a bit and explore the intersection between people and wildlife and suggest that we would also be wise to consider how we integrate animals into our urban stories, poems, art, culture and collective narrative.  We need to bring the same level of creativity and imagination that we are currently investing in transforming our physical landscape into repopulating our mental landscape with the diversity of life that surrounds us.

In short, we need to do a better job telling animal stories  urban animal stories.

I am not talking here necessarily of ecology, biology and natural history, although ecological literacy is of critical importance.  I am taking at least one step further back into the realm of mythology, legend and folklore, about how we tell and retell our own story in a way that truly recognizes wild beings as fellow travelers on our urban landscapes.

For many years I ran Portland Audubon Society’s wildlife hospital.  There we treated upwards of 3,000 injured wild animals and responded to more than 15,000 wildlife related phone calls each year.  The vast majority of both calls and animals emanated from the urban and suburban landscape.

From International Committment to Local Action: The Singapore Experience

by Lena Chan
Singapore

The Convention on Biological Diversity (CBD) currently has 193 Parties.  It is indeed a challenge for each of the Parties, as a nation, to implement their commitments to an international convention like the CBD.  How can each Party know how successful it has been in fulfilling its obligations to the CBD?  In April 2002 at 6th Meeting of the Conference of the Parties (COP6) to the CBD, the Parties committed themselves to achieve a target of reducing significantly the rate of biodiversity loss at the global, regional and national level by 2010.

If we cannot measure quantitatively what biodiversity we have how can we manage and protect it?  If we do not evaluate our biodiversity conservation efforts, how do we know that they are achieving what they were set to do?  These were the questions that Singapore pondered over and we would like to share what we have done to help us meet our international commitments through local action.

Natural Disasters and the Nature of Cities

by Glenn Stewart
Christchurch, New Zealand

Environmental traumas are here.  Global climate is a reality that is bringing extremes in weather as we have seen recently with the devastating impacts of Hurricane Sandy in the northeast of the USA.  And in the last several years there have been massive earthquakes that have devastated cities in Japan, Haiti and New Zealand.  To manage the effects of these traumas on the urban environment, we first must identify the socio-ecological drivers governing the urban ecosystems and then ascertain the degree of departure of the “new-normal” state from the pre-trauma conditions.  Individual and institutional responses set the trajectory of recovery and subsequently create a “new-normal” not only for ecological but also social systems.

The Christchurch earthquakes that began in September 2010 provided a unique opportunity to address the impacts of traumas on the urban environment and in particular, identifying “resilient” components of coupled ecological-social systems.  In this blog I will outline a study focussing on urban vegetation succession post-earthquakes.   In later contributions I will update the findings of this study based on further data analysis and discuss other aspects, such as the effects on urban fauna, and implications and options for future urban greening thru ecological design.

We’re Number 1* (*Depending): The Values Embedded in “Most Green City” Lists

by David Maddox
New York City

Who doesn’t love a list?  The 100 richest people in the world.  The best guitar players of all time. The most beautiful beaches in the world. The world’s “greenest cities”.  The USA’s most livable cities.  The most resilient cities.  For people interested in the particular theme of the list, the lists are fascinating.  We can compare them against our own ideas and experience.  We can debate and complain about the order.  (I personally agree with Jimi Hendrix at number 1 in Rolling Stone’s list of guitar players, but think that Ry Cooder at #31 is scandalously low.)

Some lists are based on simple and easily understood data, such as the Forbes list of 2012’s richest people in the world.  Let’s accept as correct Carlos Slim Helú’s valoration ($69 billion) and agree he has the most scratch.  Among the swells, Mukesh Ambani, whose personal skyscraper towers above Mumbai and has a green wall, is a laggard and in the (relative) poorhouse at #20.  A list of the most beautiful beaches, like the guitar players, is much more subjective, but nevertheless is grounded in a set of attributes, such as the beauty of the physical setting, the soft whiteness of the sand, and so on.

The critical thing to keep in the front of one’s mind when pondering all such lists is that they are based on values, which are in turn based on concepts of what is important. Read more…

Highlights from The Nature of Cities in 2013

Many voices. Greener cities. Better cities.

A new vision of ecologically sophisticated cities has been gaining momentum. Today, in increasing numbers, scientists, designers, and practitioners create useful knowledge about the nature of cities through research and action that inspires public debate and decision makers. More citizens are becoming more engaged in the conversation about urban nature — a conversation that directly relates to today’s critical debates about the livability, sustainability and resilience of human settlements across the globe. The Nature of Cities is about people, social and ecological processes, the “space between buildings”, and even about the buildings themselves.

But let’s also be candid: there is a long way to go. Thought-leading dialogue in urban nature needs to be broadened and democratized. While there are a few dozen fantastic examples of cities leading the way on urban nature, there are almost 5,000 cities in the world with over 100,000 inhabitants — and the footprint of these cities is broader still. Only a fraction of these have the ability, tools and resources to integrate nature and green thinking into their urban planning. What we need is more sharing of the good ideas, solutions, and momentum among cities, especially solutions that can be adapted to suit  local requirements.

This blog is at least one part of the expanded and enriched conversation about urban socio-ecosystems that our increasingly urbanized world requires. The Nature of Cities platform on cities as ecological spaces launched in June 2012. Since then we’ve had over 100,000 visitors from over 1,900 cities and 140 countries. And we have grown to 60 contributors from around the world. We launched a new Global Roundtable to convene and gather conversation around specific questions every month.

A million thanks for your support and interest.

To celebrate the new year here are excerpts from a few highlight posts at The Nature of Cities in 2013. We published 86 essays over the course of the year, so these represent just a taste of the wealth of diverse thought and discussion that can be found at TNOC. There are many more just as good, about bicycles, soundscapes, mapping tools, street trees, parks…you name it, from all over the world. Here are just a dozen.

Save the rhino girlWhat Does Urban Nature-Related Graffiti Tell Us? A Photo Essay from the City of Cape Town

by Pippin Anderson
Cape Town

Whether for protest, art, comment, or signaling, as an illegal activity graffiti always challenges hegemony. An examination of nature-related graffiti in Cape Town shows a number of emergent themes around the imaginings and recalling of rural nature in cities, political statements around conservation concerns of African mega fauna, nature as beautiful and aesthetically improving and informative of a better way of life, and simply bringing depictions of nature into cities where it might be otherwise absent to soften and beautify. Graffiti in Cape Town presents cities as counter to a rural idyll, the aesthetic form as non-nature, or aesthetically requiring the remediation which natural scenes can provide, as the site of the greatest populace where ‘armies’ can be called on to take up causes, in particular in the South African context, for conservation concerns.

So if we need to listen to people about their perceptions and views on nature in cities, in order that we better promote the idea and value of nature in cities, what does this graffiti tell us? It tells us there are voices of dissent out there, personal views not captured by popular media, or standard urban form, and a desire for more nature both in cities, and beyond cities.

HurricaneSandyBeachWicked Problems, Social-ecological Systems, and the Utility of Systems Thinking

by Timon McPhearson
New York City

We had a “wicked problem” on our hands when Hurricane Sandy struck the US eastern seaboard on 29 October 2012. Sandy was dramatic, destroying 72,000 homes, causing tens of billions of dollars in infrastructural damage, displacing thousands of residents (many of whom are still displaced), and completely disrupting one of the largest regional economies in the world. However, the wicked problem Sandy posed for New York City was not the magnitude of the storm damage or any particular local disaster. The wickedness of the problem lay in exposing the sensitivity and vulnerability of the city’s complex social-ecological system, where a single storm event simultaneously decimated multiple components (and connections between components) of the city system. Read more…

Photo 6A Worldview of Urban Nature that includes “Runaway” Cities

by Shuaib Lwasa
Kampala

In Africa, and particularly Kampala, where we have undertaken research on various aspects of urban development, we are increasingly confronted by a realization that urban built up components are only conveniently “detached” from the urban nature on which these sit. In fact the combination of the built up and urban ecosystems is creating a unique urban form that is a fusion of interacting parts of the city as whole. Cities in other parts of the world that have benefited from long standing planning have the urban form which, to a degree, separates built up from nature areas as nature parks and recreation areas (Grimm et al. 2008). The design and planning has also reserved multi-purpose green parks, as seen in recent urban development, to respond to the environmental change challenges. In contrast, cities in Africa, as is the case of Kampala, can be described as ‘runaway’ cities by nature of the sprawl and fragmentation of natural ecosystem interwoven with built up land. This is a different worldview of urban nature with implications on how to maintain ecosystem functions. Read more…

Public open spaces as the basis of planning are an effective means to achieve critical social objectives in cities — an approach that engages citizens, leads to better quality life and ensures a more ‘democratic’, more equitable city. By achieving intensive levels of citizens’ participation we wish to engage and influence governments to devise comprehensive plans for public spaces and re-envision the city with open spaces being the basis for planning including the vast natural assets of the city.

MayahsLotCoverA Comic Book Sparks Kids Toward Environmental Justice

by Rebecca Bratspies
New York City

Our comic book, Mayah’s Lot, challenged students to translate their grade-school civic lessons into a real-world appreciation for how to use law to achieve environmental justice. The environmental justice curriculum built around Mayah’s Lot, helped these students cultivate not only an understanding of how public policy decisions are made, but also a keen appreciation for the points at which citizens can fruitfully intervene in that process. It taught them to use citizen science to generate data, and to make their interventions as persuasive as possible. Students began identifying environmental problems in their neighborhoods.

IMG_9402Cities as Refugia for Threatened Species

by Mark McDonnell
Melbourne

In our current efforts to create green, healthy and resilient cities and towns we (I include scientists, conservationists, architects, designers, planners, engineers, landscape architects, land managers, decision makers and teachers) have an obligation and the ability to create urban ecosystems that will support a diversity of organisms that can help preserve our natural heritage at local and regional scales. As a result of the research conducted by the staff and students of the Australian Research Centre for Urban Ecology (ARCUE) over the last decade, I believe we can move beyond living with a fairly common and limited pool of urban adapted species in our cities by explicitly creating urban ecosystems that provide habitat and resources for a diversity of organisms, including threatened species.

Where will children learn about nature? There has been so much building and development in Japan that we have lost open space and natural areas. So, where will children learn about nature? Where do they engage with the nature world? To solve this problem, we wanted to design biotopes within school grounds. These spaces would serve as both play and engagement areas. They also serve real ecological functions as natural areas. Read more…

LLArchitecture and Urban Ecosystems: From Segregation to Integration

by Kaveh Samiei
Tehran

Architecture is the profession of designing the built environment. But we architects should include the contributions experts in related fields like landscape architects, urban design and planning, permaculturalist, and policy makers. Each has a significant role in restoring balance between buildings, cities and our biological / ecological inventory. Surely ecological urbanism without ecological architecture is impossible. How can architects utilize ecological science to design cities and buildings which are in harmony with ecosystems?

SystemsInACityUrbanophilia and the End of Misanthropy: Cities Are Nature

by Mary Rowe
New York City

Fortunately, the life sciences have indeed come to our rescue in urban dialog, over time out-jockeying the mechanistic, linear-ists, persuading us in many aspects of living to look at what is generative, organic, connected to the whole. Jane Jacobs observed city life as inter-connected with the natural and built environments, and her ideas have prompted a contemporary approach to urbanism that integrates uses and users, green architecture and design, local economies (even currencies!), adaptive reuses, and ecological infrastructures. These reflect Jacobs’ recognition that cities — when permitted to — evolve naturally, adding form and function as needed. Jacobs’ method was a simple scientific one: to observe the particular, and extract from it her observations about how cities actually work. Read more…

GiraffeNairobiRe-imagining Nairobi National Park: Counter-Intuitive Tradeoffs to Strengthen this Urban Protected Area

by Glen Hyman
Paris

Nairobi is a bustling city of over 3 million people, many of whom are stuck in traffic for hours each day. One effort to mitigate these wasteful jams involves construction of additional motorways. But with little space specifically reserved for these new arteries, their proposed routes involve some delicate tradeoffs. One such road, the proposed Southern Bypass, is planned to run along the eastern boundary of Nairobi National Park. As presently designed, 150 acres of park land would need to be degazetted (i.e., lost) to accommodate the new road. Several nature conservation organizations have joined together to oppose the project, and a pending legal action has provisionally halted all construction. One might understand this story as a tale of local conservation organizations banding together to “hold the line” — protecting a parcel of wilderness from the bulldozers of urban expansion. But in an urban system as complicated as Nairobi, context truly matters. In fact, the project presents a rare opportunity, if leveraged aggressively, to expand and strengthen the integrity of Park while letting the Bypass go forward.

I visited Austin, Texas to participate in the SXSW Eco conference. Staying across the street from Austin’s large and beautiful convention center, I was astonished to discover a green ravine immediately adjacent to the mammoth building, at the bottom of which was a slow moving creek full of small fish and a large turtle sunning on a rock. I soon learned that this was Waller Creek, a relatively short urban stream in a very highly developed area. I also learned that the stream is currently the focus of an ambitious public-private partnership to restore the stream and connect its banks with neighboring parks, creating both a recreational amenity and an ecological improvement.

by Cecilia Herzog
Rio de Janeiro

We are living extremely intense and interesting days in Brazil, as in several other countries. People want to be heard and to be part of the game! In this historically peaceful country, suddenly masses gathered in the streets with more than 1 million citizens marching in one single day! And the protests continue. The problems are complex and quite intricate, but in my view, there is an important factor that is not being considered: people want to live in cities that are livable. Livable cities are those in which people matter and in which nature matters. During the last years I have seen how urban dwellers praise their trees and green areas, and how they are trying to protect them against creating cities “business as usual”, based on car-centric transportation and sprawl. I love when I go to urban parks and they are packed with curious and happy families, with people of all ages enjoying trees, birds, monkeys, squirrels, and flowers… and life! Read more…

West Hayden island  (c) Sallinger (3)Lessons from a One-eyed Eagle

by Bob Sallinger
Portland

Somehow it seems fitting that a one-eyed eagle calls West Hayden Island home. By all rights, the island should have been paved over long ago. Despite the odds, it somehow survived, decade after decade as the landscape around it developed. The odds are against it now too. The big money and conventional wisdom say development is inevitable — we need to prepare for the future. But sometimes the conventional wisdom is wrong; sometimes we need to think beyond the experts or perhaps seek out different sources of wisdom. Sometimes the path forward is written not in technical reports, but on the side of a canoe and in the stories of our fellow travelers, the stories that usually don’t make it into technical reports.

A one-eyed eagle is still a long shot. Not every bird survives. Not every story has a happy ending … but if she can fly, let her go. Let her have her freedom. Read more…

 

 

 

 

 

 

Highlights from The Nature of Cities in 2014

Many voices. Greener cities. Better cities.

It’s been a great year at The Nature of Cities. The number of contributors has grown to almost 170, and we published 100+ blogs, long-form essays, and global roundtables. Most important, we’ve attracted more and more readers: in 2015 we had 170,000+ visits from 2,812 cities in 140 countries. Thank you.

New things are coming in 2015: a complete site redesign and additional types of content, including book reviews and podcasts. We’re embarking on a couple of new projects: concepts of justice for green cities and urban nature-themed graffiti. Plus some things too fresh to talk about yet. And of course, 100 new essays and roundtables.

Today’s post is offered as a celebration of some of the content from 2015—a taste…a combination of TNOC writing from around the world that was some combination of widely read, a novel point of view, or somehow caused a stir. All 100+ TNOC essays and roundtables are great reads. What follows is a sample of some of the highlights.

All the best for 2015 from TNOC.

by Timon McPhearson

Cities around the world are making plans, developing agendas, and articulating goals for urban resilience, but is urban resilience really possible? Resilience to what, for what, and for whom? Additionally, resilience is being used in many cases as a replacement for sustainability, which it is not. Resilience and sustainability need to be linked, but with care and clarity. Read more…

by P.K. Das

How do we deal with this complex web of conflicts and contradictions for the achievement of more humane and environmentally sustainable streets, and in place of highly unequal roads in favour of cars? How do we make cities and their streetscapes more livable? Reclaiming some of the street space for pedestrians and trees is part of the answer. These spaces need to be planned to be more amenable for people and nature; that is, more livable. A significant movement presently under way in Mumbai called “Equal Streets”. Read more…

picture6The New is Well Forgotten Old: Scandanavian Vernacular Experience on Biodiverse Green Roofs
by Maria Ignatieva and Anna Bubnova

In the last two decades, the technology of creating green roofs has become standardized.  The most popular today are extensive green roofs with a thin substrate layer and several succulent drought tolerant species such as Sedum and Sempervivum. But the most recent trend in ecological design is creating biodiverse green roofs that can be seen as a valuable urban biotope and substitute of the lost terrestrial habitat during building construction process. In this sense the Scandinavian vernacular experience of green roofs can be a very valuable foundation for modern researchers and designers. Read more…

bettervariedstreetshotThe Nature of a City Economy: Towards an Ecology of Entrepreneurship
by Vin Cipolla and Mary Rowe

There is an ecology to the city, a pattern of reciprocal connections that underpin its resilience. We see this in the landscape and topography that (hopefully) informs the constructed city, and then in the design of human-made services of city-life, like transit and street grids, public spaces that serve as recharge areas (in all sorts of ways), and in the ways that water and energy and food are transmitted through the city.

(1)It’s Not Only City Design—We Need to Integrate Sustainability Across the Rural-Urban Continuum
by François Mancebo

In the minds of many people, sustainable urbanization is identified with the historical model of European cities, with their dense center and their suburbs. Thus, “compact cities” are often perceived as the universal model of urban transition to sustainability. I’d like to ask two very simple questions, however incongruous they might seem: Is it feasible? Is it desirable? Read more…

The world we perceive is a world created by ourselves through our experiences, which reflects our expectations, needs and goals. Gibson, in his environmental perception theory, asserted that objects are perceived according to the meaning, action and behaviour involved and not according to the physical characteristics they possess. All of this influences how we plan, design and manage our cities. Read more…

by Oliver Hillel and Jose Puppim

Certainly we need a global legitimate organization like the UN to support the coordination of global efforts. But this is not enough. Global efforts will have impacts on the ground only if we have good local governance in a significant large number of localities. Thus, understanding the mechanisms governing urbanization, arguably as the largest human movement in history, is key to protecting the global environment, and for global politics and governance systems. Read more…

tnoc.image.04.mellesSweet by Nature: African Cities and the Natural World
by Lesley Lokko

The relationship in most tropical climes between the natural and the manmade (for want of better terms), is profound: heat and humidity combine to ensure a fecundity that is fierce, almost fearful. Inert matter—concrete, glass, metal, wood—must fight nature in order to survive, maintain, remain. Things rot, disintegrate, weather and decay at a rate that far exceeds anything more milder climes contend with. Nature’s vitality is evident everywhere. Yet we speak little of nature, even less about it. It seems to me that there’s a missed opportunity somewhere to think deeply and creatively about what nature means to us, and to translate those narratives into built/grown/planted/managed form.

Many voices. Greener cities. Better cities.

Today’s post is offered as a celebration of some of the content from 2015—a taste…a combination of TNOC writing from around the world that is a combination of diverse, widely read, a novel point of view, or somehow disruptive in an useful way. Certainly all 350+ TNOC essays and roundtables are great reads. What follows is a sample of some of the highlights.

2015 has been a transformational year at The Nature of Cities. The number of contributors has grown to over 350, and we published 100+ long-form essays, reviews and global roundtables. This year began a new format—collections of essays as an eBook. The first was The Just City Essays, a collaboration with the Max Bond Center for the Design of the Just City and NextCity. We will continue to do two of these collections a year on topics important to TNOC’s mission. Most important, we’ve attracted more and more readers: in 2015 we had 200,000+ readers from 3000+ cities in 145 countries. Thank you.

New things are coming in 2016, including:

  • New focus on green cities and social justice.
  • The Nature of Graffiti gallery of nature-inspired urban graffiti and street art.
  • An new effort to recognize and reward on-the-ground Champions of the Nature of Cities.
  • And of course, over 150 new essays, reviews and roundtables.

http://www.thenatureofcities.com/the-just-city-essays/
Over the past decade, there have been conversations about the “livable city,” the “green city,” the “sustainable city” and, most recently, the “resilient city.” At the same time, today’s headlines—from Ferguson to Baltimore, Paris to Johannesburg—resound with the need for a frank conversation about the structures and processes that affect the quality of life and livelihoods of urban residents. Issues of equity, inclusion, race, participation, access and ownership remain unresolved in many communities around the world, even as we begin to address the challenges of affordability, climate change adaptation and resilience. The persistence of injustice in the world’s cities—dramatic inequality, unequal environmental burdens and risks, and uneven access to opportunity—demands a continued and reinvigorated search for ideas and solutions.

Taking “resilience” out of the realm of metaphor. How do you measure resilience in cities? How would you know if your city or your community was resilient?
http://bit.ly/1dhNPK7
In a time of gathering stresses from climate and ecological change, economic stress, and the persistent challenges of sustainability, justice and livability, resilience is a key area of thought with enormous potential. We must continue to work to bring it down from the 10,000 meters of metaphor to functional concepts on the ground. As we build and improve the cities of world, how can we act on the core ideas and promise of resilience? Of the 21 respondents to this roundtable, some are working on direct or indirect metrics. What makes them relevant and validated? Some are measurement skeptics. If it can’t be measured then how can we construct resilience (in an adaptive management sense)? Some are actively engaged in city building and policy. How is resilience an actionable concept?

http://bit.ly/1zQWc8U

Two key issues determine whether a town or city is ‘bird-friendly’. One is the range and quality of habitats that prevail, together with opportunities for food and nest sites. The second is the culture of the place: whether birds are protected, encouraged, tolerated or shot. So to be truly bird-friendly, a city needs to have citizens who value biodiversity and influence both bottom-up and top-down decisions on how to manage the urban environment.

Urban water fronts have typically been sites of heavy development and often are sites of pollution or exclusive access. But they have enormous potential benefits. How can we unlock these benefits for everyone? Are there ecological vs. social vs. economic tradeoffs?http://bit.ly/14sr2ai
Cities are necessarily heterogeneous and multiple: they are sites where we encounter difference and where humanity and nature come crashing up against each other. Cities both embrace and abrade nature in the same turn. Urban waterfronts are no different in that they serve as the point of contact between the ‘wilderness’ of the open sea or river and the city that lines its shore. Waterfront developments have an opportunity to reconnect cities to their marine or riverine ecologies, but also run the risk of being neither ecologically sound nor socially inclusive. They may become segregated urban spaces just like so many others that turn their backs to the cities where they are situated, or they may become the centrepiece of the city itself, engaged as a powerful tool to attract citizens and visitors to the aquatic urban edge.

Beijing LandfillWays Forward from China’s Urban Waste Problem
Judy Li, Beijing
http://bit.ly/1D7hAWS
It is important to consider the human element of China’s urban waste system to understand how it affects the livability of Chinese cities. In addition to poor waste collection infrastructure, investment, and enforcement, the current waste system in China perpetuates social inequalities for rural-to-urban migrants. Landfills and incubators are pushed to the outskirts of the city where poor migrants live. This leaves the wealthier inner city areas relatively clean, but their waste is exported to small towns and poor communities that are socially, politically, and economically marginalized. Wiser resource utilization can help Chinese cities become more sustainable, and address environmental injustices of the current waste system.

Democratizing Conversations on Sustainability to Create Resilience from the Soul
Diana Wiesner, Bogotá
http://bit.ly/1JHGugu
There are multiple proposals revolving around the discourse of sustainable cities, in which green infrastructure systems are implemented and natural resources are protected to guarantee ecosystem service supply. This discourse, however, is concentrated among scholars, specialized professionals, and a limited percentage of the population. As a result, city planning and its corresponding sustainability proposals are far removed from the people who are building their spaces in terms of trends, as other groups that have settled in these territories have done before them, without taking into account water, vegetation, or open space. This has to change.

London: A National Park City
by David Goode, London
http://bit.ly/1NlYwJH
Over the past 18 months, a movement has been growing, drawing together Londoners who want to apply National Park principles to the whole of Greater London. The aim is to turn traditional attitudes to the city inside out, ensuring that nature has a place in every aspect of London’s fabric and making it accessible to every Londoner. The idea has gained huge support from many different sectors of society. It’s a people’s movement that is gaining momentum by the day and, last month, a draft charter was launched for public consultation.

Making the Measure: A Toolkit for Tracking the Outcomes of Community Gardens and Urban Farms
Phil Silva, New York
http://bit.ly/1Cq05yK
Community gardeners and urban farmers across North America are using an innovative research toolkit developed in New York City to measure and track the impacts of their work. The toolkit is made up of sixteen different methods for collecting data about things like the number of pounds of food harvested in a community garden or the number of children who develop a taste for fresh vegetables after hanging out at a neighborhood farm. Gardens around North America have started using the toolkit and its accompanying online data-tracking site, “The Barn”. The toolkit is freely available for anyone to download, use, and repurpose. The Barn data-tracking site is also free and open to any community garden or urban farm throughout the world.

Micro_Urban: The Ecological and Social Potential of Small-Scale Urban Spaces
Timon McPhearson and Victoria Marshall, New York and Newark
http://bit.ly/179wVdq
Small-scale urban spaces can be rich in biodiversity, contribute important ecological benefits for human mental and physical health, and overall help to create more livable cities. Micro_urban spaces are the sandwich spaces between buildings, rooftops, walls, curbs, sidewalk cracks, and other small-scale urban spaces that exist in the fissures between linear infrastructure. What if the micro_urban were the missing piece to solving the connectivity puzzle in our fragmented urban ecologies? How might micro_urban habitats, networked throughout our built and social infrastructure, make a difference in the social and ecological well-being of a city?

Yet reinvigorating our bond with nature is a challenge architecture and urban design are well placed to address. Architects and designers have control over our built environment; by changing the way we design cities and buildings to connect to rather than disconnect from nature, we can change our proximity to nature and shift our physical relationship to the environment.

05 Mirror glass in VancouverWhy We Need Design Guidelines for Urban Non-Humans
Paul Downton, Adelaide

Every city, every town and human settlement, should have a set of urban design guidelines for non-human species. The development and application of these guidelines would form the core of a new adventure in urbanism that has transformative potential and the capacity to lay the groundwork for a truly ecological civilisation—in which taking care of non-human species will, in turn, enhance the capabilities and conditions of the human animal.

Count me inCount Me In: Urban Greening and the Return of Primates in Kampala
Shuaib Lwasa, Kampala
http://bit.ly/1IDK1uI
Kampala plans to plant 500,000 trees, a greening activity that is part of the effort to build climate resilience in the city. It has been envisaged to have multiple benefits. Green cover would enhance aesthetics, reduce common flash floods through increased infiltration, and sequester greenhouse gases. But one unforeseen possibility of the greening program is the return or increase of the primate population in the city as habitat is re-created. To this end, it is important for planners and practitioners of urban space re-creation in Kampala to think about tree species that would attract the return of primates, whose persistence has continuously communicated that they will not be left out of the city. If there is appreciation of urban spaces that create harmony between nature and built forms, how can the greening activity be utilized to improve habitats and return primates to Kampala? What would be the motivations for increased biodiversity in the city?

For all the critical scholarship that is written about the harnessing of volunteer labor in caring for urban trees, it never squared with my experience of engaging in stewardship. I came to realize that my leisure practices were missing from my research accounts. I was writing myself out of the story. I’ll share three stories of my engagements with street trees and reforestation sites to explore affective experiences between me and the trees. I believe that these vignettes offer windows into why and how we create and maintain relations of care with the urban forest. How can we build bridges between such emotional experiences and our management practices and cultivate attachment and stewardship; that allows attachment to inform management, decision-making, and priority-setting?

The Secret Life of Bees: Using Big Data and Citizen Science to Unravel…What Bees Are Saying about the Environment
Jennifer Baljko, Barcelona
http://bit.ly/1APt5jN
Bees can act as a biosensor for cities, and give a signal that could be easy to understand. If the bees are all right, we are living in a good environment. If the bees are suffering or the colony is dying, it could be a sign that the environment is having serious problems. Recent studies, for example, suggest that bees are sensitive to pollution, and small fluctuations in ozone levels can affect their behavior. Researchers behind a Barcelona project hope that insights generated from data on beehive temperature, humidity, and weight, might provide clues to creating healthier and sustainable environments for bees, for humans, and for cities.

Steven Handel, New Brunswick
http://bit.ly/17JYkSQ
Ecologists and Landscape Architects can have a rocky and unsteady relationship; improving it is going to take some time. I can’t promise a happy ending, of course, but ask you to remember three things: First, your goals for a sustainable, healthy landscape are parallel, not divergent. Keep that in mind when you seem to have momentary troubles communicating. Second, you are both driven to improve the landscape, not watch it continually degrade; remember you’re soul mates, at least in that way. Third, we live in a rapidly changing world, climate, sea levels, movement of species, and mixing of biotic communities. These are all spinning fast towards a future that is hard to predict. Ecologists and designers are our only real protection against the troubles ahead. We need you to work together. Don’t let us down.

PK Das, Mumbai
http://bit.ly/1L99Md0
Can we re-envision our cities with a stream of linear open spaces, defining a new geography of cities? Can we break away from large, monolithic spaces and geometric structures into fluid open spaces, meandering, modulating and negotiating varying city terrains, as rivers and watercourses do? This way, the new structure of open spaces would relate to and integrate with many more areas and provide access to more people across neighborhoods and the city.

26. MaddoxCities in Imagination
David Maddox, New York
http://bit.ly/1Pvy4yR
These are the cities of our dreams: resilient, sustainable, livable, just. Let’s imagine. We can imagine sustainable cities—ones that can persist in energy, food and ecological balance—that are nevertheless brittle, socially or infrastructurally, to shocks and major perturbations. They are not resilient. We can imagine resilient cities—especially cities that are made so through extraordinary and expensive works of grey infrastructure—that are not sustainable from the point of view of energy consumption, food security, economy, or other resources. We can imagine livable cities that are neither resilient nor sustainable. And, it is easy to imagine resilient and sustainable cities that are not livable—and so are not truly sustainable. Easiest of all is to imagine cities of injustice, because they exist all around us. The nature of their injustice may be difficult to solve or even comprehend within our systems of economy and government, but it’s easy to see.

William Dunbar, Tokyo
http://bit.ly/1KVlP8b
The concept of biocultural diversity— the coming together of biological and cultural diversity—is receiving more attention recently along with an awareness that elements of cultures all around the world are deeply rooted in the nature, or biological diversity, around them, and that greater cultural diversity comes with greater biological diversity. It seems intuitively true that richer biological diversity leads to richer cultural diversity if you think about the wide variety of art, rituals, traditional knowledge, etc. that are related to nature and are integral to indigenous peoples and local communities around the world. Empirically as well, greater cultural diversity has been shown to correlate with biodiversity hotspots.

Trees of Life and Fruitful Relationships
Patrick Lydon, San Jose & Seoul
A review of Arboreal Architecture: A Visual History of Trees, an exhibition at the Cantor Arts Center, Stanford University
http://bit.ly/1O6chKU
The show’s curator, George Philip LeBourdais, has shoehorned a global collection of artworks from the Cantor Center’s collection into the room. Spanning about 1,500 years, the collection is impressive not only for the time it covers, but because all of the works concern the trees and our ever changing cultural relationships with them.  The exhibit offers a deep and powerful display of cultural relationships to trees over such a great cultural timespan that it’s impossible not to be affected by it. The works speak of trees in city and countryside, of trees in in ritual and for utility, and, perhaps most importantly, of trees as part of us and, ultimately, as works of art themselves.

24_Central Park_BC_2013What Makes a “Great” City Park? The Beholder Sees
Adrian Benepe, New York
A review of “Great City Parks”; Second Edition, by Alan Tate with Marcella Eaton
http://bit.ly/1XHrubm
Park geeks and urban nemophilists, not to mention the “designers, administrators, planners and politicians with current and future responsibilities for city parks” that the author cites as the primary target audience, have reason to celebrate and pore over this lovingly detailed volume, richly illustrated with photographs (most of them by the authors) and simple plans of the parks, and heavily annotated with quotes, citations, and footnotes. But what is a “great” park? Alan Tate offers this: “There is no easy answer. Well, there is. It’s like being in love. You know when you’re in it and that gels with Burke’s definition of beauty as ‘that quality or those qualities in bodies by which they cause love.”
CrosswalkHow Tactical Urbanism “Adds Up”

A review of Tactical Urbanism: Short-term Action for Long-term Change, by Anthony Garcia and Mike Lydon
http://bit.ly/1CSiCsi
Tactical Urbanism: it’s one of the buzz words in the emerging people-centred planning paradigm. If you do a Google News search of the term, you’ll find articles from all the news sites beloved by urbanists. These many meanings are captured in the new book by American urban planners Anthony Garcia and Mike Lydon, both leaders in civic advocacy and principals of The Street Plans Collaborative. By clearly laying out what tactical urbanism is—the authors define it simply as an approach to neighbourhood building and activation using short-term, low-cost, and scalable interventions and policies—the groundwork is laid to build on this theory of change by providing successful examples and providing guidance for making it work in practice.

Complex and Useful, Green Is Infrastructure
Ana Faggi, Buenos Aires
A review of Green Infrastructure: A Landscape Approach
http://bit.ly/1DrPVCw
Green Infrastructure: A Landscape Approach, in line with the current principles of sustainability, discusses green infrastructure (GI) as the visible expression of natural and human ecosystem processes that work across scales and contexts to provide multiple benefits for people and their environments. It gives the reader a framework for a sustainable urban and regional future, how can it be implemented, and how planners and designers can play leading and responsive roles in addressing these issues. Although this report was intended for planners, landscape architects, architects, civil engineers, scientists, and others interested in the spatial structure, functions, and values (environmental, economic, and social) of natural and built landscapes, its simple and enjoyable writing makes it useful for educators, students, citizen groups and conservationists. While all case studies were drawn from communities within the United States, implementing the mentioned principles through green infrastructure initiatives, the variety of contexts and scales make them applicable worldwide.

The Myths of Alien Species: An Alternate Perspective on “Wild”
by Divya Gopal, Berlin
A review of The New Wild: Why Invasive Species Will Be Nature’s Salvation, by Fred Pearce
http://bit.ly/1KaSh8V
The New Wild is an intriguing book that looks at non-native species and nature in new light, challenging popular notions of ‘nativism,’ ‘wild’ and nature’s ‘fragility.’ Although the author, Fred Pearce, has taken on a controversial topic, his sources show that he is not alone as an increasing number of ecologists and scientists are questioning the “good natives, bad aliens,” narrative. As an ecologist who works in cultural landscapes, I found this book is refreshing. ‘Wild’ to me means spontaneous and not domesticated or cultivated. There is something magical about seeing what nature has to offer. Many of the spontaneously growing plants, often considered weeds elsewhere, add character to the city. Some are natives, some aliens. It doesn’t matter—these spontaneous species are the new wild.

http://bit.ly/1OwJ8wJ
Before becoming India’s information technology hub, Bengaluru was known for its numerous lakes and green spaces. Rapid urbanization has led to the disappearance of many of these ecosystems. Those that remain face a range of challenges: residential and commercial construction, pollution and waste dumping, privatization, and so on. Today, Bengaluru’s lakes are principally seen as garbage dumps and sewage ponds that can have either of two fates: one, be transformed into recreational oases to suit the needs of wealthy residential neighborhoods, or two, be encroached upon until none of the original shapes and functions can be traced. But how does this affect the lives of the people living at the very margins of Bengaluru’s beloved yet contested lakes?

Imaging the Urban Wild: Fourteen Photographers and Artists Show and Talk About their Work
http://bit.ly/1cVEsQ0
Photography, and art in general, can help us see. See in new ways. Indeed, it helps us be better at looking. One of the main themes of The Nature of Cities is the idea of “nature nearby”—that cities are not barren of nature, but rather teem with life, both human and non-human. Yet many people in cities don’t see that nature around them, though they may sense it as part of the nature, or character of their city. Can we learn to look more thoughtfully, and therefore see more fully the natural vibrancy that is all around us in cities? And also along the way see what vibrancy our cities may be lacking? It is a vibrancy that weaves—or should weave—together nature and people and built form in ways that make cities rich—rich in biodiversity, human society, sustainability, resilience, and livability. So in the spirit of looking more deeply, more finely in ways that can help us see, this is the first of what I hope will be many roundtables on artistic and creative expression on the nature of cities. As is TNOC’s way, the 14 represented here take diverse routes to seeing and sensing the city. What details do they find to make the city more vivid?

Highlights from The Nature of Cities in 2016

Many voices. Greener cities. Better cities.

Today’s post celebrates highlights from TNOC writing in 2016. These contributions, originating around the world, were widely read, offer novel points of view, are somehow disruptive in a useful way, or combine these characteristics. Certainly, all 550+ TNOC essays and roundtables are great and worthwhile reads, but what follows will give you a taste of this year’s key and diverse content.

2016 has been an important year at The Nature of Cities. The number of contributors has grown to almost 600, and we published 150+ long-form essays, reviews, and global roundtables. We launched the  The Nature of Graffiti, a crowd-sourced gallery of street art from around the world that includes themes from nature and the environment. We partnered with Jenn Baljko as she walks from Bangkok to Barcelona over three years, reporting on the cities and communities she encounters. We published a pre-publication of 10 chapters from an urban environmental education book that will appear in its full form in 2017. In essays, roundtables, and reviews we continued to seek the frontiers of thought found at the boundaries of urban ecology, community, design, and art. Importantly, we’ve attracted more and more readers: in 2016 we had over a half million readers from 2,500+ cities in 150+ countries. Thank you.

New things are coming in 2017, including:

  • An urban eco-poetry series, in collaboration with ArtsEverywhere.ca and Musagetes Foundation;
  • A collaboration with Ray Cha, funded by the Transit Center, to produce education modules for better utilization of open data produced by cities;
  • A new book addressing the justice and equitable access imperatives of the benefits of ecosystem services;
  • As an outgrowth of our Nature of Graffiti project, we will embark on the beginning stages of an interactive, creative exhibit of art on social-environmental themes in urban “vacant” lots, generously funded by the U.S. National Endowment for the Arts;
  • And of course, over 150 new essays, reviews and roundtables.

Roundtables

Can cities save bees? How can urban habitats be made to serve pollinator conservation? How can that story be better told?
bit.ly/2h7F1uP

Bees and pollinators have always been a part of the city landscape, but increasing interest in urban conservation, agriculture, and gardens, has made their presence more noticeable—and more important. Bee and pollinator conservation is a key concern outside of cities too, with habitat loss, indiscriminant insecticide use, and other issues threatening bee species and pollinators generally. What role can cities play in bee and conservation? How can this role be supported, by both public and private actors? And how can the story of urban pollinators be better told to propel the conversation about urban pollinator conservation and their critical services?

Visions of resilience: Eighteen artists say or show something in response to the word “resilience”
bit.ly/1WbnLV1

“Resilience” is the word of the decade, as “sustainability” was before it. A challenge with both words is that while they exist so well in the realm of metaphor, they are more difficult in reality. The same can be said for “livability” and “justice”. In this roundtable, we aimed to strike out in possibly new metaphorical directions. We invited 18 artists and designers of various types to respond—in words, images, or other works—to the word “Resilience”.

This Roundtable was a co-production with Arts Everywhere, where these responses are also published.

Common threads: connections among the ideas of Jane Jacobs and Elinor Ostrom, and their relevance to urban socio-ecology
bit.ly/2hZm2Uv

Jane Jacobs and Elinor Ostrom were both giants in their impact on how we think about communities, cities, and common resources such as space and nature. But we don’t often put them together to recognize the common threads in their ideas. Yet, their streams of ideas clearly resonate together in how they bind people, economies, places, and nature into a single, ecosystem-driven framework of thought and planning—themes that deeply motivate The Nature of Cities. In this roundtable, we asked 16 people to talk about some key ideas that motivate their work, and how these ideas have roots in the ideas of either Jacobs or Ostrom, or both.

What, how, and where are examples of graffiti as a positive force in communities?
bit.ly/2hbr5Qz

Graffiti and street art can be controversial. But they can also be a medium for voices of social change, protest, or expressions of community desire. In many cities, graffiti is associated with decay, with communities out of control, and so it is outlawed. In some cities, it is legal, within limits, and valued as a form of social expression. “Street art”, graffiti’s more formal cousin, which is often commissioned and sanctioned, has a firmer place in communities, but can still be an important form of “outsider” expression. Interest in these art forms as social expression is broad, and the work itself takes many shapes—from simple tags of identity, to scrawled expressions of protest and politics, to complex and beautiful scenes that virtually everyone would say are “art”, despite their sometimes rough locations. What, how, and where are examples of graffiti as a positive force in communities?

This roundtable was a co-production of The Nature of Cities and Arts Everywhere, where these responses are also published. Also check out The Nature of Graffiti, a gallery launched in 2016  that illustrates some of these ideas from an environmental perspective.

Urban agriculture has many benefits. Is one of them a contribution to urban sustainability?
bit.ly/2ifOwKk

Sustainability is key to our future, and, as urbanization steadily grows, keys to increased global sustainability must be found in cities and how they use and are provided with resources. In this topic, there has been much excitement about urban agriculture—the production of food in and near cities at scales larger than home or community gardens. Does urban agriculture have the potential to contribute significantly to urban sustainability by reducing cities’ dependence on food grown at great distance from the city? Can it produce enough to address food insecurity? In this roundtable, we asked respondents to address the potential for urban agricultural production to make cities more sustainable, and how such potential could be realized.

Essays

Confronting the Dark Side of Urban Agriculture
François Mancebo, Paris
bit.ly/22jcKio

Some people praise urban agriculture as a kind of panacea that could help reconfigure more sustainable cities by bringing people together and, eventually, reshaping the whole urban fabric. But it is misleading to greenwash, without caveats, conventional or high-tech agriculture in the city as sustainable. All urban agricultures are not sustainable, and some may even produce deleterious effects on city inhabitants, as well as on the city itself. In this essay, François Mancebo sets out to distinguish between the types of urban agriculture and to denounce those which, under the disguise of promoting agriculture in the city, promote practices that are absolutely unsustainable.

Market-Based Solutions Cannot Forge Transformative and Inclusive Urban Futures
Richard Friend, Bangkok
bit.ly/2hh2RpM

Richard Friend uses an analysis of a Dhaka advertisement to assess what a classic neoliberal response to environmental degradation could mean for Asia’s city dwellers as the effects of climate change worsen and the New Urban Agenda remains absent from the discussion. “It seems that even while the combined effects of climate change, environmental degradation, and social injustice are more in evidence now than ever,” he writes, “the overall direction of responses is a toxic combination of individualist, market-based solutions, alongside growing, heavy-handed political oppression. The calls for solutions to the challenges of climate change uncertainty and risk to embrace participation, innovation, and informed dialogue amid polycentric, multi-scalar governance mechanisms seem all the more distant”.

Why Conserve Small Forest Fragments and Individual Trees in Urban Areas?
Mark Hostetler, Gainesville
bit.ly/1TX6IEq

For many developers and city planners, it takes time and money to plan around trees and small forest fragments. Often, the message from conservationists is that we want to avoid fragmentation and to conserve large forested areas. While this goal is important, the message tends to negate any thoughts by developers towards conserving individual mature trees and small forest fragments. Mark Hostetler demonstrates how fragmented landscapes have value for a variety of species—and why stating that fragmentation is unequivocally bad can only lead to lost conservation opportunities.

Viola Has an Acorn in Her Pocket
Stephan Barthel, Stockholm

Stephan Barthel’s daughter, Viola, age 4, is curious about the nature that surrounds them on their father-daughter walks in Stockholm. Her questions prompt her father to muse on a wide ranging of subjects, from the importance of ecological memory, to the possible impact of the Smart City paradigm on future development and education, to the gentle wisdom of singer-songwriter Nick Drake.

They are Not “Informal Settlements”—They are Habitats Made by People
Lorena Zárate, Mexico City
bit.ly/1YRQpaY

According to the UN, at least one third of the global urban population suffers from inadequate living conditions. Lack of access to basic services, low structural quality of shelters, overcrowding, dangerous locations, and insecure tenure are the main characteristics normally included in the definitions of so-called informal settlements. In this essay, Lorena Zárate argues that words matter: changing the words means changing the concepts; changing the concepts means changing the way we understand (or not) complex phenomena and are able (or not) to transform them in a positive way. These “informal settlements” are neither informal nor irregular— they are, above all, human settlements.

Climate Adaptation Plans Can Worsen Unequal Urban Vulnerability
Linda Shi, Boston; and Isabelle Anguelovski, Barcelona
bit.ly/2hjAeqm

To date, few studies have asked: who actually benefits from urban adaptation plans and projects? Do projects prioritize the vulnerability of the most disadvantaged and marginalized groups? Do projects succeed in reducing vulnerability and, if so, for whom? In this essay, Linda Shi and Isabelle Anguelovski argue that there is an urgent need to find examples where climate adaptation and resilience projects have moved towards more equitable outcomes and to identify specific normative principles, design strategies, and evaluative outcome metrics for alternative adaptation strategies that highlight equity and justice.

Sense of Place

Different people perceive the same city or neighborhood in different ways. While one person may appreciate ecological and social aspects of a neighborhood, another may experience environmental and racialized injustice. Jennifer Adams, David A. Greenwood, Mitchell Thomashow, and Alex Russ explain how sense of place—including place attachment and place meanings—can help people appreciate ecological aspects of cities. This is a chapter from the book Urban Environmental Education Review, which will appear in 2017. TNOC published ten chapters as a pre-publication.

“These days, especially in summertime, we have heavy rain in Japan,” writes Keitaro Ito. In response to the increasing frequency of flooding, he has turned to Sado, a traditional  tea ceremony, to inform the biocultural design of small rain gardens that can provide an important ecosystem service: stormwater management.

From Reactive to Proactive Resilience: Designing the New Sustainability
Nina-Marie Lister, Toronto
bit.ly/22gbWQF

Long-term sustainability necessitates an inherent and essential capacity for resilience—the ability to recover from disturbance, to accommodate change, and to function in a state of health. In this sense, sustainability typically means the dynamic balance between social-cultural, economic, and ecological domains of human behavior necessary for humankind’s long-term surviving and thriving. As such, long-term sustainability sits squarely in the domain of human intention and activity—and, thus, design. This should not be confused with managing “the environment” as an object separate from human action, which is ultimately impossible. Instead, the challenge of sustainability, says Nina-Marie Lister, is very much one for design, and specifically one of design for resilience.

Urban Nature that Reduces Risk in Kampala
Shuaib Lwasa, Kampala
bit.ly/2hncXUp

Kampala’s urban landscape has been largely fragmented, just like the landscapes of many other cities. In fact, this is the common character of urban development. But it isn’t the only way. In this article, Shuaib Lwasa illustrates the urban risks that Kampala faces—especially those related to natural hazards, such as floodingand demonstrates how these risks can greatly be reduced through greening and restoration of nature in lowland and hilltop forests.

Wouldn’t it be Better if Ecologists and Planners Talked to Each Other More?
Diane Pataki, Sarah Hinners, and Robin Rothfeder; Salt Lake City
bit.ly/2iwFt3Y

At first glance, one might think that the fields of ecology and planning communicate regularly with one another. But they don’t—at least, not enough. The contact between these disciplines rarely occurs as a direct collaboration between practicing ecologists— whose job is to generate new scientific understanding—and practicing planners, whose job is to envision and plan better cities. If planners and ecologists found more ways to work together, would cities look different? Would they be better? Yes, they would, say  Diane Pataki, Sarah Hinners, and Robin Rothfeder as respond to this question with a case study from Salt Lake City.

The Forgotten Rurality: The Case for Participatory Management in Bogotá and its Surrounding Countryside
Diana Wiesner, Bogotá
bit.ly/2hHS842

We often think of the city and the country as separate, and that development planning and urban sustainability ends at the city boundary. But this isn’t true—in a planning and sustainability sense, the city and the surrounding rural areas are deeply linked. With this in mind, Diana Wiesner discusses a plan for the sustainable coexistence of a section of forgotten rurality near the megacity of Bogotá, Colombia, and how a civic response is being molded to draw attention to the issues involved.

Designing Ecologically Sensitive Green Infrastructure that Serves People and Nature
Christine Thuring, Sheffield
bit.ly/2hrFgmg

Green infrastructure is expanding and gradually softening a proportion of our planet’s increasingly urban surface. Yet, from her perspective as a plant ecologist, Christine Thuring argues that many green infrastructure installations miss their full ecological potential. While monoculture is better than concrete, diversity is generally better than monoculture. The ideal of green infrastructure, she says, is two-fold: it must be multi-functional and it must express ecological sensitivity.

Rachenahalli, one of the few living lakes of Bangalore, India, is an example of a thriving social ecological system. As documented in Sumetee Gajjar’s photographs, it provides natural resources to people living around it, acting as a sink for fisher folk cleaning fish or for women doing Sunday laundry and receiving treated sludge from new residences around the lake, as well as from an upstream sewage treatment plant. In these ways, the lake continues to live and to support life.

Justice and Geometry in the Form of Linear Parks
David Maddox, New York City

Here at The Nature of Cities, we write a great deal about the benefits of “green” cities, widely construed. Green infrastructure is good for human health and quality of life, it reduces the carbon footprint of cities, it increases resilience by insulating us from storms, it helps create foci of community building, and so on. Furthermore, green cities are good for nature in the form of conservation. But in cities around the world, everyone does not currently enjoy these benefits. If we ask how to increase access to ecosystem services via parks, then linear parks are a good answer, writes David Maddox.

Knowing vs. Doing: Propelling Design with Ecology 
Anne Trumble, Los Angeles
A review of Projective Ecologies, edited by Chris Reed and Nina-Marie Lister 
bit.ly/2ho8TmR

If we cannot get our most innovative and challenging ideas out of books and into real landscapes, we will squander an opportunity to determine a proud future. Projective Ecologies turns to ecology for new ways to think beyond the old nature/culture split. Offering up the insight that we may not be making the most of a diverse and complex concept of ecology, is, perhaps, the greatest success of Projective Ecologies.

What Should We Make of Jane Jacobs’ Critique of Parks in The Death and Life of Great American Cities?
Podcast produced by Philip Silva, New York

While it’s true that Jane Jacobs changed the way we think about cities, relatively little is ever said about her views on urban parks. In honor of the 100th anniversary of Jacobs’ birth, we took a moment to revisit her views on “the uses of neighborhood parks” as she laid them out in The Death and Life of Great American Cities.

Intertwining People, Nature, and Place with Quilts and Thread
Patrick Lydon, San Jose & Seoul
A review of Earth Stories, an exhibition at the San Jose Museum of Quilts and Textiles

The idea that material and thread can communicate so much about our human relationships with our urban and natural environments isn’t so wild. If we’re working to save anything, whether it’s a forest or a culture, one can’t help but think how much easier it is to save that something when one has a personal relationship with it. In this way, much of what Earth Stories accomplishes is in bringing enough familiarity to the gallery wall that we might more easily re-establish these relationships.

How Did Seoul’s Cheonggyecheon River Restoration Get Its Start?
Podcast produced by Philip Silva, New York
http://bit.ly/2ifowMw

A casual chat on a bus nearly thirty years ago led to the improbable removal of a major elevated highway and the restoration of a beloved river in the old city center of Seoul in South Korea. Dr. Soo Hong Noh, a professor of environmental engineering at Yonsei University, became a champion for bringing back the Cheonggyecheon River in his home city after listening to a colleague fancifully muse about the river’s restoration while they sat together on their evening commute.

The High Line. Foreseen. Unforeseen.
Adrian Benepe
A review of The High Line. By James Corner Field Operations and Diller Scofido + Renfro 
bit.ly/2ix0wqT

New York City’s High Line Park, once a rusting relic of abandoned freight rail transportation infrastructure, has become arguably one of the world’s best-known urban parks, and possibly the single most visited park in the United States—and perhaps the world—on a visitor-per-acre basis. The High Line—the book recording the process of bringing the park to fruition—is, in the end, a sensual experience reflecting the High Line’s creation, design, and current reality.

Poetry Produces the Novel Language of Future Cities
Laura Booth
A review of Urban Nature: Poems About Wildlife in the City

How can poems advance our understanding of nature in cities? Poetry, with its capacity to invert the lexicons of “nature” and “culture” so that they are not artificially divided per our current paradigms, is uniquely positioned to play a role in visioning future cities.

Nature in Chicago: Surprisingly Wild, Surprisingly Human

A collection of stories, poems, drawings, and photographs contributed by numerous Chicago artists, scientists, and residents, City Creatures whisks the reader through the streets, parks, and history of the Chicago region, giving a perspective on the city’s relationship with nature that is at once complete, nuanced, detailed, entertaining, and surprisingly intimate.

Highlights from The Nature of Cities in 2017

Many voices. Greener cities. Better cities.

Today’s post celebrates highlights from TNOC writing in 2017. These contributions, originating around the world, were widely read, offer novel points of view, are somehow disruptive in a useful way, or combine these characteristics. Certainly, all 1000+ TNOC essays and roundtables are great and worthwhile reads, but what follows will give you a taste of this year’s key and diverse content.

Check out highlights from previous years: 2016, 2015, 2014, 2013, 2012.
2017 has been an important year at The Nature of Cities. The number of contributors has grown to over 650, and we published 150+ long-form essays, reviews, and global roundtables. We have conducted an ongoing survey of reader desires for types of context and we’ve been planning new efforts.  We launched the Stories of the Nature of Cities 2099 prize for Flash Fiction. We began a collaboration with Ray Cha, funded by the Transit Center, to produce education modules for better utilization of open data produced by cities. We had the first physical meeting of TNOC writers, in Portland, where we discussed the possibilities for a global TNOC meeting.

In essays, roundtables, and reviews we continue to seek the frontiers of thought found at the boundaries of urban ecology, community, design, and art. Importantly, we’ve attracted more and more readers: in 2017 we had over a half million readers from 2,500+ cities in 150+ countries. Thank you.

New things are coming in 2018, including:

  • We are working toward incorporation in Ireland, creating an organization foothold in the European Union;
  • A series of collaborative poetry in place-making, called TransRengas, in collaboration with ArtsEverywhere.ca and Musagetes Foundation;
  • We hope to announce soon a series of international transdisciplinary TNOC meetings;
  • As an outgrowth of our Nature of Graffiti project, we will embark on the beginning stages of an interactive, creative exhibit of art on social-environmental themes in urban “vacant” lots, generously funded by the U.S. National Endowment for the Arts;
  • And of course, over 150 new essays, reviews and roundtables.

Roundtables

Are cities ecosystems—analogous to natural ones—of nature, infrastructure and people? Does thinking about cities in this way help us think about urban design?

Are cities ecosystems in the senses in which we think of classic natural and ecological areas outside of cities? After all, urban spaces are connected mosaics of green space, biodiversity (including people), non-biological structure, biophysical processes, energy flows, and so on. That sounds a lot like a natural ecosystem. Many of these contributors say, yes, certainly, cities are ecosystems. Not all, though. A few more are skeptical that an ecosystem concept is central to planning better cities. The more common belief among this group might be that a socioecological and landscape approach to cities is more important, and one that is imbued with values.

Who should have access to the myriad benefits of ecosystem services and urban nature? Everyone. Does everyone? No. What now?

Do we truly believe in the benefits of ecosystem services? If so, then who should enjoy these benefits? The answer is self-evident: everyone. But do all city residents around the world currently enjoy these benefits? No. What is the answer to this challenge? Is it just about building more green infrastructure? Building smarter? Being clear about “ecosystems for whom?” Or perhaps something more radical is needed—a fundamental reinvention of our economies?

You say po-TAY-to. What ecologists and landscape architects don’t get about each other, but ought to.

In the creation of better cities, urban ecologists and landscape architects have a lot in common: to create and/or facilitate natural environments that are good for both people and nature. And yet, they are still two distinct professions, and so there are ways in which they may say similar sounding things but mean something different. How can we get them better integrated in the service of better cities?

What are we trying to accomplish with biophilic cities? What are ambitious goals and targets, and measures of success?

As a design imperative, biophilia indicates that cities are more livable when they have more nature. But is biophilia an actionable driver of design in cities? If so, what should cities have as targets or goals for biophilia? If the aim is to create a “biophilic city”, how would you know when it was achieved?

Imagine an “ecological certification” for urban design. What are such a certification’s key elements?

Urban sites get planned, designed, and built. Many are called “sustainable” or “ecological”. Are they so? And who makes the evaluation? We gathered 15 designers and ecologists to talk about ecological design certifications. They were invited to celebrate or criticize existing systems, if they cared to. Mostly they were prompted to discuss key principles and metrics that would make the phrase “ecological design” harmonize the words ecological and design.

To whom does a city’s nature belong? Is it a common pool resource, or a public good? And who decides? 

Who decides what happens to city spaces of nature? Is it the community that lives closest to the sites? The entire city? Conflicts between these two different conceptions of to whom the “goods” of urban nature belong are fundamental to many urban contestations. Fourteen TNOC contributors describe examples of urban nature as public goods, as commons—or, most often, as intermingling of both.

Essays

Singapore through the Eyes of a Young Planner in Manila
Ragene Palma, Manila

How has Singapore created itself as a “city in a garden”? As a Manila planner, my trip there was eye-opening. I live in a metropolitan area that favors a built-up environment, and always viewed green spaces as isolated areas for beautification, or as something held aside until a developer decides to use for more profit. Singapore shows that my everyday normal could be so much more.

Ostrom in the City: Design Principles for the Urban Commons
Sheila Foster, Washington, DC & Christian Iaione, Rome

Ten years ago, we began to explore the governance of the urban commons as a separate body of study—how different kinds of urban assets could be reconceived as urban commons, and later to conceive the whole city as a commons. Where there is a network of urban commons, we begin to see the transformation of the city into a commons.

Seven Things You Need to Know about Ecocities
Paul Downton, Melbourne

An ecocity is about ecological health. It is conceived in aspirational terms because we don’t yet know even half of what we need to know to make the concept real. But the assertion of the ecocity is an article of faith: the idea is strong enough to set development and political agendas, and can be understood by the wider community. Only then can people engage with it and live the idea.

How to Make Urban Green Verdant and Sustainable: Designing “Wild” Swedish Lawns
Maria E Ignatieva, Uppsala

Stockholm, is a famous “green” city. But, ordinary urban landscapes in Stockholm and other Swedish cities were mostly created during an period of fascination with lawns. Research suggests that Swedes like lawns, but many also desire a more biodiverse landscape. So, how can we design “wild” nature in urban environments?

Ecologies of Elsewhere: Giving Urban Weeds a “Third Glance”
Daniel Phillips, Bangalore

Volunteers. Exotics. Aliens. Weeds. Cities are full of novel ecosystems. Should we include them in our definitions of “urban resilience”? A growing body practice says yes. Indeed, new modes of engaging with the urban landscape will not be based on superficial aesthetic concerns or sentimental rear-view thinking, but a celebration of the messy complexities of novel ecosystems, and the active role they will play in the nature (and future) of our cities.

Crossing the Design-Science Divide
Jason King, Seattle

Designers and scientists are different. We think, communicate, and interact with the world in vastly different ways. The challenges are immense, but to expand the potential of projects we need to mediate the disconnect between science and design, building on positive strategies by ecologists and designers to increase collaboration and success.

Restoring Indigenous Trees for Scaling Up City Resilience: The Role of African Millennials
Aliyu Barau, Kano

It is crucial for municipalities in African countries and beyond to tap into millennials to achieve the SDGs. Millennials have the capacity and energy to engage their peers, younger and older generations who look up to their innovative energies, aspirations, and commitment to rebooting environmental wellbeing and welfare. At MR CITY Lab, our approach is practical. University student millennials make contact with communities and introduce tree species into neighborhoods with tree toponyms.

Five Reasons to Conserve Nature in Kampala
Shuaib Lwasa, Kampala

Cities in developing countries have many challenges—poverty; deficiency in infrastructure; high risk to climate-induced. Less literature or practice views these cities as sites of opportunities for enhancing ecological processes that have local as well as regional and global benefits. Here are five reasons why Kampala’s nature, if conserved, can enhance ecosystem services.

Walking on Rivers — Dry Riverbeds as Public Parks?
Sareh Moosavi, Melbourne

Dryland settlements were historically established along flowing rivers, where freshwater bodies sustained the communities for centuries. But this is changing. In most arid regions of the world, cities are growing and rivers are running dry. Global warming and misuse of water resources increasingly leave dry riverbeds in their wake. Rapid urbanisation has left little room for creating new public open spaces, but could urban riverbeds that remain dry for an extended period of time provide potential for new public parks?

World Enough: Tales from the Bottom of the Garden
Katrine Claassens, Montreal

A painted essay with text. Excerpt:
When you drive at night from Cape Town city centre into its suburbs, there’s a scent that hits you as you get to Kenilworth, a sweetness in the air that spills from our gardens into the street. Kenilworth is pretty established, but I remember in Johannesburg, in the 80s, when we lived in the new suburb of Sunninghill. A place where the wildness was not quite bred out yet. The lawns were were still being coaxed out from the veld and paper thorns were a feature of any barefoot venture.

What the Zika Epidemic Means for Gender and Urban Adaptation Planning in Brazil
Katerina Elias, São Paulo

Two years ago, South America was swept up in a public health crisis that affected hundreds of thousands of women across the continent. In Brazil, more than 2,600 children were born with the microcephaly and other health complications resulting from the viral infection Zika. But the end of Zika doesn’t begin with the eradication of a mosquito: it requires a systemic, intersectional analysis to help identify how social, economic, urban, health and other structures shape women’s lives, power, and their vulnerability to climate impacts and access to resources.

Of Flash Floods and a Lost Indian Waterscape
Hita Unnikrishnan & Harini Nagendra, Bangalore

In the weeks prior to the writing of this article, the city of Bengaluru was reeling from torrential rainfall. Effects of this downpour were felt in many ways—flash floods, trees uprooted, lives lost, and traffic standstills. Several lakes breached their banks, while minor rivers like the Vrishabhavati, which have not held water within city limits for decades, came back to life. It made people realize the faulty infrastructural planning of the city. The story of the Dharmambudhi lake serves as a reminder of the fact that disrupting the connectivity of a waterscape can have serious implications.

Where Can I Dream? Eight Stories of Life in Bogotá / ¿A donde puedo soñar? Ocho relatos de vida en Bogotá 
(Essay in English & Spanish.)
Diana Wiesner, Bogotá

In pondering the question, “Who should have access to the countless benefits and services that urban ecosystems provide?”, we put together a collection of eight first-person accounts that portray city dwellers’ dreams. These sketches of life explore both individual and collective human experiences as participants narrate their lives and reveal their innermost thoughts. These acts of remembrance provide a key to human identity and give meaning and substance to daily life.

Can Smart Cities be Smart Green Cities? We’ll See
Gary Grant, London

As yet, there are no smart cities, although plenty of people and organizations are working hard to create them: initiatives, policies, strategies, and some projects, but no examples of cities where it all comes together. In addition, most of us are still wondering what is meant by the term “smart city”. Smart cities are coming… eventually. When they do, it is important that they be as much about nature, health, and wellbeing as traffic flows, crime detection, and evermore efficient provision of utilities.

Reviews 

Designing Urban Nature: The Domain of Ecologically Informed Planners or Landscape Architects?
Will Allen, Chapel Hill

As I opened the handsomely large Nature and Cities: The Ecological Imperative in Urban Design and Planning, I was pleased to see a quote from Ian McHarg near the front. Through a conference and now this book, Nature and Cities has successfully advanced the urban nature literature—even for a McHarg disciple like me!

How Large Parks Complete Cities
Lynn Wilson, Vancouver

It would be hard to imagine the world’s great cities without their iconic parks. Large Parks, edited by Julia Czerniak and George Hargreaves, helps readers understand the complexities inherent in designing, planning, and managing these often contested public spaces, and I have a greater appreciation of the challenges that they face now and into the future.

Biophilia’s Place in an Integrated Approach to Urban Planning
Mike Wells, Bath

Tim Beatley brings us a useful primer on incorporating biophilia into planning and design in his new Handbook of Biophilic City Planning and Design. Based in part on case studies from The Biophilic Cities Network, the handbook moves the biophilic city concept an additional step in the direction of an integrated approach to urban design.

New York’s Central Park as Muse, as Imagination, as Home
Mary Mattingly, New York

Reading Painting Central Park, by Roger Pasquier, convinced me that, although a term usually reserved for ornamental architecture that is out of place, parks in cities are all follies to an extent. Through being out of place they insist we confront difference. Artists who paint the landscape inside of the city are drawn to these differences. With a preface by Amanda Burden—asserting a human necessity to engage with flora amidst urban life—Roger Pasquier writes and shows an homage to Central Park.

Urban Farming for Everyone / La Agricultura Urbana para Todos
Francois Mancebo, Paris

Graciela Arosemena’s intruiging book “Agricultura Urbana – Espacios de Cultivo para una Ciudad Sostenibles / Urban Agriculture – Spaces of Cultivation for a Sustainable City” (with facing pages in English and Spanish) not only considers the merits of urban agriculture, it also provides insight, knowledge and techniques to make urban agriculture an activity accessible to everyone.

 

Highlights from The Nature of Cities in 2018

Many voices. Greener cities. Better cities.

Today’s post celebrates some of the highlights from TNOC writing in 2018. These contributions—originating around the world—were one or more of widely read, offering novel points of view, and/or somehow disruptive in a useful way. All 1000+ TNOC essays and roundtables are worthwhile reads, of course, but what follows will give you a taste of 2018’s key and diverse content.

Check out highlights from previous years: 20172016, 2015, 2014, 2013, 2012.
The Nature of Cities advanced in a number of ways in 2018. The number of contributors has grown to over 700, and we published 150+ long-form essays, reviews, and global roundtables.

We founded a sister Charity registered in Ireland—The Nature of Cities-Europe—in order to collaborate more with our colleagues in the European Union.

The Stories of the Nature of Cities 2099 prize for Flash Fiction attracted 1200 entries from 116 countries. We awarded seven top prizes (all seven were women, from the U.S., Canada, and India), and in February 2019 we will publish a book of 57 stories from 21 countries. The top story, by the way, is called “Neither Above Nor Below”, by Claire Stanford of Los Angeles. We’ll run a second edition of the prize in 2019, with theme “Set in a City Park”.

We began serious planning for The Nature of Cities Summit, to be held in Paris in June 2019. Join us there for a really innovative meeting focused on transdisciplinarity and collaboration in green cities.

In essays, roundtables, and reviews we continue to seek the frontiers of thought found at the boundaries of urban ecology, community, design, planning, and art. Importantly, we’ve attracted more and more readers: in 2018 we had over a half million readers from 2,500+ cities in 150+ countries.

Thank you. We hope to see you again in 2019.

What is one thing every ecologist should know about urban ecology?

In November 2017, Nature Ecology and Evolution published a major review of the field of ecology, titled “100 articles every ecologist should read” (behind a paywall, unfortunately)—a product of an extensive survey of ecologists. In addition to a lack of gender and racial diversity among authors, and its general lack of inclusivity, the list also includes nothing of how urban ecology has contributed to our understanding of our urban planet. So, we asked a diverse group to create a list of some of the most important contributions from urban ecology for advancing the field of ecology. (We asked them to suggest a reading also—a start on a reading list.)

An urban planner and an urban ecologist walk into a bar. They chat about how (and maybe whether) “ecology” could play a bigger role in planning…

Urban planning (and the city plans that express it) is typically focused on coherently organizing city systems, flows of people and resources, where things are and should be. While parks, green and open spaces are usually part of urban plans (but there are unfortunate exceptions), ecology and ecological processes are on the sidelines. Much of the writing at TNOC addresses the essential ecological and social values that flow from ecosystem services, green spaces, and biodiversity. So, should not a greater ecological sophistication be embedded within urban planning? Should there not be ecologists at the center of urban planning teams in cities? Of course, this requires that ecologists get involved, learn about planning and its methods, and invest in the tradeoffs that are inevitably involved in planning something as complicated as a city. Where are the examples ecology embedded in urban planning? How can it be done?

As a landscape architect, how do you interpret the word “biodiversity”? How does this meaning find expression in your design?

The word biodiversity is one of those words that lives happily in metaphor. But in detail, it is all over the map. Ask 10 people, you’ll get 13 definitions. Even ecologists use diverse definitions, that sometimes make distinctions between native and non-native species, but sometimes not; that alternate between indicating species or ecosystems and their services; and sometimes in the same conversation. And then there is the subtle and not so subtle distinctions between definition, meaning, and action. Landscape architects are the practitioners of biodiversity’s meaning through their acts of shaping nature into “spaces”. They have their hands on definitions of biodiversity that they use in their work, and that we experience in the landscapes their create. But they aren’t necessarily the same definitions as a scientist’s. Or even a regular person’s. So, how do landscape architects view the word “biodiversity”? How does it find meaning in their work?

Artists in Conversation with Water in Cities

For this, our second roundtable in the series “Artists in Conversatuion with…”, we invited eleven artists to present their conversation with water in cities. Coming from seven different countries—Czech Republic, France, Mexico, South Africa, Spain, Turkey, and the United States—these artists inspire our own experiences with water in cities. They engage with water in the shape of fog, rain, ice, restored wetlands, urban rivers and creeks, city fountains, and reclaimed urban spaces. To them, water is an inclusive moving matter that when listened to, can serve as a conduit to larger understandings.

Nature Atlas: Exploring Multi-scalar Methods for Mapping Urban Environments
Ruchika Lodha and Timon McPhearson, New York

Engagement is the first step toward active acknowledgment, inclusion, and stewardship of the environment. Nature Atlas provides a rich tapestry of options for engaging with urban nature. The purpose of Nature Atlas is to invoke diverse ways of perceiving, understanding, and engaging nature by actively and consciously interacting with our environments through various practices across disciplines, inclinations, expertise, and capacities.

Neural Networks—A New Model for “The Kind of Problem a City Is”
Mathieu Hélie, Montréal

Jane Jacobs’ final chapter of Death and Life of Great American Cities, titled “The Kind of Problem a City Is”, remains its most misunderstood. The principal ideas of the book have become the mainstream of urban know-how and helped the triumphant turnarounds in the fortunes of American cities, most notably for New York City. But the last idea in the book—that the scientific foundation that is the basis of the planning profession is founded in error—has not had the same impact. The debate over the scientific basis of urban planning was set aside. The non-linearity of neural networks provides a useful illustration of how details can matter in complex systems, but also of the importance of iteration for adaptation. Is it possible for our cities to learn and adapt as neural networks do?

The Nature of Public Art: Connecting People to People and People to Nature
Georgina Avlonitis, Cape Town

Mankind may have left the savannah some million years ago, but the savannah never quite left us. It makes sense that since we co-evolved with nature, our need for it is hardwired into our brains and our genes. Urban nature and public art can help to break down barriers both mental and physical, sparking imaginations, catalyzing placemaking, forging new connections, and bringing people together. In a GreenPop project, disused public corners in two African cities—Livingstone, Zambia and Johannesburg, South Africa—were transformed using public participation, mural art, public seating, sculpture, and indigenous plants into spaces of connection and of conversation around the incredible biodiversity that makes each city so unique and special.

Secular, Sacred, and Domestic—Living with Street Trees in Bangalore
Suri Venkatachalam and Harini Nagendra, Bangalore

In rapidly growing Indian cities, change seems like the only constant. Heritage buildings are torn down, roads widened, lakes and wetlands drained, and parks erased to make way for urban growth. Nature is often the first casualty in a constant drive towards development. Yet the street tree stubbornly survives across Indian cities—beleaguered by gasoline fumes, besieged by construction, but still tenaciously gripping the sidewalk. The lives of street trees are emblematic of the multiple entanglements that characterise the nature-society dialectic animating the ever expanding urban in the global south—entanglements that knit together the past and present, the secular and sacred, and the global and local.

Urban Metabolism: A Real World Model for Visualizing and Co-Creating Healthy Cities
Sven Eberlein, Oakland

Like the human body, cities are living, ever-evolving organisms. Just as diet, exercise, sleep, or laughter can be seen as indicators of our personal physical and emotional well being, the ways in which goods, water, commuters, or food move through the urban ecosystem determines a city’s health and sustainability within larger regional and global natural systems. With citizen-generated maps and diagrams based on real-life conditions and structured around a holistic framework, the patterns that emerge allow for both residents and planners to ask questions that can lead to both local and regional ecological improvements.

Socioecological Science is Failing Cities. The Humanities Can Help
Diane Pataki, Salt Lake City

I am very much a practicing research scientist and not a humanist, but sometimes our traditional methods simply fall short of the questions that need to be answered. When it comes to the intersection between ecological processes, the built environment, and the experience of living in modern cities, this problem is both acute and urgent. If there is a chance that the arts, literature, philosophy, and other humanist disciplines have something to offer our understanding of what urban ecosystems are and can be, then I think we should explore that chance, and quickly.

The Sheffield Street Tree Massacre: Notes from a Public-Private Partnership Gone Wrong
Christine Thuring, Sheffield

Often described as Europe’s greenest city, Sheffield is reputed to have more trees per capita than any other, with over 100,000 trees spread across parks and open spaces, 10.4 percent woodland by area, and approximately 36,000 street trees. However, a public-private partnership is dramatically altering Sheffield’s urban forest. Sheffield exemplifies the worst-case scenario when private companies are contracted to finance and deliver public goods, and a noteworthy example of creative and resilient community activism.

Hearing from the Future of Cities
Diana Wiesner, Bogotá

What happens when we “freeze” the landscape on pieces of paper? To find the answer, for the past eight years our foundation, Fundación Cerros de Bogotá, has been inviting children from Bogota and the surrounding region to paper our walls with their landscape drawings. (Bogotá is a humid tropical city located at 8,700 feet above sea level, on a highland plateau in the eastern range of the Andes.) Last year alone, children from diverse backgrounds sent us more than 2,000 drawings of Bogotá’s mountains and their surroundings. In pondering all of these children’s drawings and listening to their stories about their interests, we began to realize that these children would be our greatest allies in bringing about the changes we have been dreaming about.

Three Case Studies in Re-wilding: Models and Methods for Other Cities to Consider
Kevin Sloan, Dallas-Fort Worth

Re-wilding is a new area of interest in landscape architecture concerned with making landscapes that are as close to the original ecology of a place as possible. Not limited to only planting installations, re-wilded landscapes can also exist to attract, reconstitute and/or re-introduce wildlife to heighten biodiversity. Re-wilding beckons landscape architects to embrace a logical next step…to release artistic conceits altogether and replace them with the actual landscape type naturally intended, as much as is realistically possible.

A Sense of Wonder: The Missing Ingredient to a Long-Term Value for Nature?
Bronwyn Cumbo, Sydney; and Marthe Derkzen, Amsterdam

What are the types of childhood experiences that instil a lifelong value for nature and promote stewardship behaviour later in life? It turns out that the sense of wonder that children experience in nature is a crucial factor. Over 60 percent of children around the globe live in cities where they face substantial barriers to regular and direct experience of nature. In addition to the numerous implications the absence of nature-based experiences has for the health and development of children, an increasing proportion of children are exhibiting a limited understanding of common plants and animals, as well as a biophobia (“fear” or ambivalence) towards the natural world.

Civic Coproduction = Counterinstitutions + People: Make Participation Work by Focusing on the Possible
Nik Luka, Montreal and Uppsala

Conventional wisdom tells us that deliberative democracy works best at local scales thanks to superior and immediate access to decision-makers, the tightness of feedback loops for citizens, deciders, and third parties (expressed by the notion that disgruntled citizens will “vote with their feet”), and the importance of local places to self-identity. But where it is presumably easiest to engage in deliberative democracy, it also seems most challenging. Even when full-blown deliberative democracy is not possible in complex societies, we can strive for a more modest goal: “civic coproduction”, which concerns the many grassroots initiatives that we now see in cities and landscapes. Even where the complex needs and desires of diverse publics must be conjugated with scarce resources, people and civil society are participating and making a difference.

Earthquakes, Constitutions, Urban Planning and Social Change: Lessons and Controversies from Mexico
Lorena Zárate, Mexico City

For better or worse, 2017 was a historic year for both Mexico and Mexico City. This can be summed up in two numbers: 100 and 32. The first number celebrates the one hundredth  anniversary of Mexico’s Constitution, approved on 5 February 1917, and renowned as the first Constitution in the world to incorporate social rights. The second number, 32, marks the remembrance of the deadly earthquake that killed more than 30,000 people and devastated Mexico City on 19 September 1985. Two very different anniversaries, of course. One, but distant and hardly provoking any popular emotion; the other one random and unforeseen, but still very present in the memories of at least three generations. Struggles for spatial justice, human rights, and democracy are interconnected and have a long history in Mexico City. As the previous official slogan claimed, this is a “City in Movement”. So let’s get inspired and keep going.

The stack and its vapor are blue if the weather is clear; red the night before rain to alert citizens to reduce their use of water and reduce pressure on the storm water system.

Water Marks: An Atlas of Water for the City of Milwaukee
Mary Miss, New York

As an artist, having the opportunity to develop a project at the scale of a city has been a remarkable experience. WaterMarks has grown out of a three-year engagement with the city of Milwaukee. City government, academic institutions, and many nonprofits have been essential contributors to the development of this urban-scaled project.

Focusing on water, the project has three important goals in mind: address environmental issues as a gateway to sustainable development; engage communities as active partners; help identify Milwaukee as a global water center.

Call and response as a means of dialogue: Physical interventions call out some aspect of the natural systems and infrastructure and, through community engagement activities, the people of Milwaukee respond to and activate the sites.

A Bengaluru that Endures in Essence, Yet Constantly Transforms
Pippin Anderson, Cape Town

In her book Nature in the City: Bengaluru in the Past, Present, and Future (OUP, 2016), Harini Nagendra suggests we draw on the “cultural imagination and capacity for coexistence” demonstrated through the long history of the city of Bengaluru as we strive for sustainable and resilient modern cities. This call for considered and creative action is an appropriate directive in an age of rapid and dynamic urbanization. Her book is fascinating in that it simultaneously meets the directive of contemporary urban ecology in addressing the social and the biophysical, and also shares a personal lived experience of a city.

A Hymn for Architecture that is Good for People and Neighborhoods, not Just Buildings
Samarth Das, Mumbai

John Cary’s Design for Good comes at a time when it is so important to re-instill the hope that design brings to people—both designers as well as the people designed for. It sheds a ray of light into the design world by demonstrating how, through incorporating public dialogue and involvement, we can achieve end results that are hugely successful. If two young postgraduate aspirants from MIT have the drive and urge to explore beyond their comfort zones to eventually help communities in Rwanda—as did the MASS Design Group in the case of the Butaro Hospital project—then established professionals in the field can certainly take up the mantle and attempt to do the same.

New Integrated and Actionable Urban Knowledge for the Cities We Want and Need
Thomas Elmqvist, Stockholm. Xuemei Bai, Canberra. Niki Frantzeskaki, Rotterdam. Corrie Griffith, Tempe. David Maddox, New York. Timon McPhearson, New York. Sue Parnell, Cape Town. Paty Romero-Lankao, Boulder. David Simon, Gothenburg. Mark Watkins, Phoenix.

Urban Planet draws from diverse intellectual and practice traditions to grapple with the conceptual and operational challenges of urban development for sustainable, resilient, livable, and just cities. The aim is to foster a community of global urban leaders through engaging the emerging science and practice of cities, including critiques of urbanism’s tropes. We hope that ideas about global urbanism that situate the city at the core of the planet’s future will provide pathways for evidence-based interventions to propel ambitious, positive change in policy and practice.
