The Nature of Cities Europe

Did you know that baby housemartins speak in their sleep? I did not ― until some nights ago in early July. I was walking down the deserted main road outside Varese Ligure, an old-fashioned Italian mountain town. It was the evening of the day I had arrived. Following the dimly...

India is roasting, with some cities like Delhi pushing to almost 50 degrees C (122 degrees F). In India’s recent election, at least 33 poll workers died while doing mostly compulsory work to administer the election in sweltering polling places. All told, there have probably been thousands or tens of...

A biking lane should measure 4.20 meters at minimum in the city of Utrecht. Sidewalks need to be 1.20 meters wide to make sure pedestrians and a person in a wheelchair can pass each other. For each house we build we add 0.78 parking spaces in the public domain. In...

Background to the Sustainable Financing Gap Globally, challenges in making our cities resilient are multi-dimensional and are on the rise. According to the 2023 Sustainable Development Goals Report, over half of the global population currently resides in urban areas, a rate projected to reach 70% by 2050. Approximately 1.1 billion...

Rightly, people recently have been valuing Indigenous cultures and writing about them. Not wishing to mimic or appropriate, but as an attempt to learn from such ways of thinking, this essay uses a form of circular storying[1] that becomes nonlinear. I stumbled upon ‘storying’ (the making and telling of stories)...

Nestled within the lively and restless Leith neighbourhood stands the iconic curved structure of Cables Wynd House, immortalised in Irvine Welsh’s novel “Trainspotting” and referred to by locals as the Banana Flats. Constructed in the 1960s, Cables Wynd is considered one of Britain’s greatest post-war buildings designed in the Brutalist...

In 2010, the UN General Assembly explicitly recognized the human right to water and sanitation. Equal access to safe and clean water, however, requires a major change in how decisions over use and rights to water are made and needs appropriate legal frameworks to curb over-extraction and unsustainable behavior. Qanats...

A view from the joint meeting of the San Juan ULTRA and the NATURA Early Career Network 1. Nature-based Solutions in the Context of San Juan, Puerto Rico On a sunny day in San Juan, Puerto Rico, life is good. Along the beaches, crabs scuttle in the riprap next to...

The White City. Thus, Tel Aviv refers to itself, taking its cue from the many buildings built in the International Style in the 1930s by the avant-garde architects who had studied in Europe or come to Palestine to escape Nazi Germany. Some had studied at the Bauhaus, and the term...

Invasive species cause one of the greatest threats to biodiversity and ecosystems worldwide. Many species are introduced into environments different from their place of origin and can quickly proliferate, causing significant harm to the ecosystems, economy, and public health. Invasive species have the capacity to establish, reproduce, and spread uncontrollably,...

[*]I’m on my way home from an errand one early June evening. As I walk, I look down on the granite-slabbed sidewalk. At its margin, a row of slender catsears raise their yellow heads towards the fading sky. They look a bit like skinny dandelions (who they are related to),...

A core tenant of the environmental movement is under attack. Planning, and particularly the rational planning model, is seen as something suspect, an enemy of the people. The whole idea of rational, technocratic planning to achieve social goals is being rejected by some, as an elitist pursuit that must be...

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...

Assessing the cooling function of urban parks under heat and drought conditions Thanks to the cooling function of the vegetation, urban parks offer cool, pleasant places in cities during hot summer days. Urban parks are also places for recreation and social interaction. In parks, people go jogging or cycling, meet...

As urbanization intensifies around the world, and the devastating effects of global warming are increasingly evident, it is vital to promote urban ecosystems as a tool to achieve ecological balance within the city. Urban ecosystems are the base to guarantee healthy and sustainable places to live, work and visit. Urban...

The Harrisons (Helen Mayer Harrison (1927-2018) and Newton Harrison (1932-2022)) are widely acknowledged as pioneers in bringing together art and ecology into a new form of practice. They worked for over fifty years with biologists, ecologists, architects, urban planners, and other artists to initiate collaborative dialogues. The works they made...

What connects all upper-middle-class houses, public institutions’ buildings, stadiums, and golf fields? A hint: it is aesthetic, it is high-maintenance, and it is a prime example of a single species use. The answer is ― the lawn. The history of lawns goes back to the late Middle Ages, and is,...

Due to urban densification processes and increasing confrontation with climate change, cities face the need to organize their public space in efficient and sustainable ways that take current needs as well as those of future generations into account. The Green Infrastructure (GI) concept is a widely used concept, introducing various...

  Playing games is a serious thing. Animals and humans learn how to relate with each other and with the world through games involving bodies and minds. Games provide a simplified way to understand complex issues, while at the same time broadening our perception of reality through multi-sensorial experiences. Playing...

Sometimes — for a day, a week, or a month — Paris turns into the very kingdom of walkers. That is, during transit strikes, when subway trains and buses stop running. Millions of walkers flood the streets, as the Métro and bus network release the load of crowded bodies it...

Urban green spaces often become entangled in notions of heritage. Multiple factors explain this convergence, from the historical origins of so many major urban green spaces, to the range of values (cultural, spiritual, etc.) that are tied to these places (see Feng & Tan, 2017; Forrest & Konijnendijk, 2005) and...

“This is a crucial and much-neglected topic. If children are not designed into our cities, they are designed out. This means that they are deprived of contact with the material world, with nature, with civic life and with their own capacities.” George Monbiot (Arup, 2020, 15) 1 Where do children belong...

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...

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...

What is it? City authorities around the world are looking for policies and tools to facilitate urban greening ― in particular, the process of bringing more soil, vegetation, and water into the built environment through the development planning system. In the UK, authorities are looking at the Urban Greening Factor...

Project study within the framework of the Swiss Biodiversity Strategy Action Plan Increasing building density is putting pressure on green spaces and thus on the living conditions for flora, fauna, and humans. However, the sixth IPPC report and the COVID-19 pandemic clearly show green spaces that enable recreation and the...

Russia’s invasion of Ukraine has exacerbated existing problems in global supply chains of two fundamental commodities, namely energy and food, which in turn are leading to soaring inflation. In response, several countries are abandoning their commitments made at the COP26 conference to reduce carbon emissions and instead going back to...

The Year 2007 marked the arrival of the Urban Millennium when most of the world’s population became urban for the first time in human history (UNDESA, 2009). The proportion is now at least 55% and the global urban population is predicted to increase by 2.5 billion over the next 30...

Last year in spring, we came up with an idea of creating a flower garden that would only feature native plant species. Why is that both difficult and important? And what conclusions can we draw after a full year of watching the flower garden grow and seeing how both community...

Informal organizational structures are commonly involved with greening efforts in cities, such as waste recycling and urban agriculture efforts. They are particularly relevant in cities of the Global South, where large percentages of the economy and labour are in the informal sector. Collaboration between the formal and informal sectors poses...

  Biodiversity faces increasing challenges with the development of cities. Land-use change, intensive agricultural management and pesticide use, invasive alien species, diseases, climate change, and environmental pollution are threatening bees and other pollinators. Helping them to survive means ensuring food security and maintaining healthy ecosystems. Nature conservation and the improvement...

At the end of November 2021, spending a few days in London, I paid a far too brief visit to the Natural History Museum. I had devoted the daylight hours to a survey of the skyscrapers burgeoning in the City’s business district and got to the museum just as the...

I wasn’t in a good shape when I broke the sparrowhawk’s wings. A gray sky over Berlin, a cold eastern wind. An early March day that never had properly lighted up and already started to sink back into dawn. No rain, no snow, but this dry and uncomfortable wind. I...

More than half of the world’s population lives and works in diverse, bustling cities. And perhaps, if you are reading this blog, you have a desire to make these places we call home greener—it can be done with nature-based solutions! Quite often city-makers who want to implement nature-based solutions run...

Like seeds planted in my brain The first time I ever heard about permaculture was in 2016. I discovered this life philosophy in the French documentaries “The World of Tomorrow” (by Cyril Dion and Mélanie Laurent), and then in “A Quest for Meaning” (by Nathanaël Coste and Marc de la...

The COVID-19 pandemic is slowly receding and, while it still is a fatally serious problem in some places, it is possible to imagine it at least receding into an endemic disease. It is perhaps, therefore, a good time to reflect on what COVID-19 has meant and will mean for urban...

UrbanA, ECOLISE, and Communities for Future joined forces to lead an experimental seed session on the first day of the amazing The Nature of Cities Festival (with online discussions on the #TNOCFestival hashtag). About 25 people turned up from different corners of the planet, on Monday 22nd of February 2021,...

Nature and greenery are good for you; we all know that by now. But is it also possible to improve your health by actively seeking out greenery or by getting involved in greenery yourself? That is, can you improve your health simply by taking an action? This is something Wageningen...

Governments and communities around the world are embracing Nature-based Solutions (NbS) as a major climate adaptation strategy. Building off of pre-existing approaches to integrating ecological and built systems, NbS attempt to meet a wide array of social goals including improving urban quality of life, supporting transit and recreation, and mitigating...

In the end, Humankind reverse-engineered the heavens and the world. And while there had been some semblance of order before, Humankind turned it all inside out, night became muddled with day, and day with night. Humankind took the carbon lodged in the darkness of the earth and expelled it into...

Bats — “they live in the dark, they eat your blood, they fly in your hair, and they spread diseases like Ebola”. At least that is what stereotypes have painted them to be Most people do not know much about bats. Since COVID-19, the reputation of bats is even worse...

The River Avon Most visitors to the city of Bath in the West of England come to enjoy its grandiose Georgian crescents, terraces, and squares, and Roman-built baths, which have been beautifully crafted from the locally mined honey-colored oölitic limestone. Indeed, the city’s magnificent architecture and Roman remains have been...

Cities around the globe are seeing increased civic interest and appreciation of nature in the city. Pictures with citizens thronging to urban parks and urban waterfronts adhering to social distancing have flooded social media and traditional media alike in the past months. This appreciation and recognition of how important it...

Things fall apart Standing at a crossroads, looking into the eye of a perfect storm, these are anxious days for humanity. The full social, humanitarian and economic fall-out of the COVID-19 pandemic may have barely come to pass but it already makes the 2008-09 global financial crisis look like child’s...

The COVID-19 pandemic has established a moment of immense global loss. In the midst of this public health crisis, our concerns for our families and communities necessarily take priority. Yet, addressing these concerns demands a look towards the future: to the reevaluation of global systems that may produce or obstruct...

Most of the inhabitable regions of the Earth were originally covered by forests, grasslands, and wetlands. These carbon-grabbing, biodiverse, spongy landscapes have been largely replaced by agriculture and urban development, which is drier, belches carbon, is erosive of soils, and which has lost most of its wildlife. Indeed, biodiversity declines...

“Science is meaningless because it gives no answer to our question, the only question important for us: ‘What shall we do and how shall we live?’ ” — Leo Tolstoy  We know that our cities need to look and function differently. There is a wealth of scientific evidence showing that urbanisation...

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...

And What Grassplots, Amur Leopard, and Mold Have in CommonWhat is biodiversity for? Some don’t need that question answered: you just adopt a philosopher’s perspective, and everything becomes clear—all living things have the right to dwell on the planet. For others, the question is confusing. Those trying to find a quantitative answer to...

“Stay home!” This is the imperative that has echoed across the planet in the last months. Everyone is at, and a, risk to themselves and others. And so we did. We mostly stayed at home. After a few days, we began to notice that our house, our cities, and our...

Since 1912 in Paris, the river Bièvre, once the city’s second-largest river, has disappeared from our landscape. It used to cross the whole left bank from south to north, flowing through the 13th and 5th arrondissements before reaching the Seine between “Le Jardin des Plantes”, our historical botanical garden, and...

Linden In early summer, after the crest of the first wave of the pandemics had broken and kids resumed to go to school and street cafés had opened again, I spent days alone writing on the balcony of a flat in a somewhat sketchy Berlin neighbourhood. Down in the street,...

We are gardening. Feeding our trees. We decide to cut the deadwood off the Fejoa tree. Afterwards it’s considerably squat and oddly shaped, but we agree it looks better. Or it feels better. Or it seems to us that it, the tree, feels better. It has just been liberated of...

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. Harald Welzer in The Climate Wars shows that the feeling of crisis as well as fear is born in the face of...

Know the feeling when every project seems to require a huge amount of work in a short amount of time, for very little reward?? This seems to be the way of the world, whether you’re a practitioner, a researcher, or a community activist (or all three). I was prompted to...

Winter may seem a quiet season when it comes to bird sounds, but when we listen carefully we may hear the starling, one of the most cheerful whistlers in the world. Mozart had a starling for some time and enjoyed the delightful singing of his bird friend, who was able...

When evaluating or seeking to enhance the biodiversity interest of an urban greenspace, a key attribute to consider is its floral composition. Floral composition can be native, non-native or a variable mix of the two. A species is defined as native to a given region or ecosystem if its presence...

There is now plenty of evidence on the benefits of local access to greenspace and greenviews on physical health and mental well-being. Lockdowns and social distancing advisories have placed restrictions on citizen normal access to public spaces. Google community mobility statistics from February-March revealed varied patterns of reaction to Covid-19 in...

The lessons learnt by teenagers today will assist us as global leaders of tomorrow, to make better and more informed decisions to prevent any such future epidemics. The Covid-19 crisis and widespread epidemic has infected more than a million people and is increasingly causing agony to billions. While the severity...

There is no doubt that cities, especially since the industrial revolution, have by and large been built overriding local ecologies, obliterating topography, soils, streams, altering soils, ignoring seasons, breezes, sunlight. Nature based solutions, urban ecosystem services, however they are called, have emerged to try to remediate this historical modernist hubris...

Could we construct a new image of what the political boundaries of an urban landscape could take shape as? Instead of the hierarchical approach that is commonplace, with cities governed by layers of neighborhood, urban, regional, and state-provincial levels through different electoral or appointed bodies, I propose to approach the...

Equity and Sustainability: a history of ideological convergence vs. practiced indifference The idea that equity is an important and indispensable part of sustainable development has been there from the early days. The intellectual basic for and actions taken towards sustainability are thought to be fundamentally fair and just—a world in...

Those last few days in June, we could see Barcelona’s shape in the distance. The three chimneys from the old power plant. The slanted roof of the Forum. The towers from the Olympic village. The long stretch of beach reaching to the glass sail that is the W hotel. The...

Nature-based solutions are emerging as a key mechanism for renaturing cities, yet barriers around evidence and effectiveness still stand in the way of widespread rollout across our urban landscapes. More by luck than design, we learned that a straightforward technical test of a Sustainable Drainage System (SuDS) retrofit scheme in...

Experimentation is a way to bring new solutions or approaches to cities. As a researcher on sustainability and sustainability transitions, I believe that, if solutions are to be adopted and scaled to improve human and ecological conditions in our world, they require testing in the field, beyond closed-door labs but...

“Co-creation” has garnered much buzz as a promising enabler of greener and better cities for all. During a hands-on session (“Co-creating inclusive green cities: European examples and global learning opportunities”) at the Nature of Cities Summit in Paris (June 4-7, 2019) with co-creation experts and cities—co-organised by Connecting Nature partners...

Human relationships with nature are highly complex and variable. Particularly now when the human connection to nature has been highly disrupted, and the sense of custodianship or stewardship has been displaced. Yet at the same time, there is a growing awareness and movement of the need to reconnect people and...

On the last week of September millions of people participated in climate strike marches around the world, protesting against global inaction on climate change.

One of the One Minute of Dance a Day project. This dance was performed on the Sorbonne campus during the TNOC Summit, outside the main auditorium venue. Beats by 3’z. There are over 700 dances, and you can search them by Paris neighborhood, site type, nature element, and more.

On a recent visit to Paris after an absence of more than a dozen years, I was struck by the comprehensive and visionary approach to urban resilience and livability that is transforming Paris into the global leader in innovative urban greening. Since my childhood, I have been entranced by the...

Walking may be my main form of transportation these days, but I often daydream about wheels…bicycle wheels…and the way they move people through urban and rural spaces. Most of our 14,000-kilometer journey to date is speckled with memories of two-wheeled riders, and my longing to join them in their pedaling...

During the past week the eyes of the world have been on London, to see a new Prime Minister installed at Westminster. But the week has also seen a momentous decision made for a sustainable and liveable future for London. The city was designated as a National Park City, the...

We noticed an extraordinary thing walking across Asia and Europe since January 2016: the absence and presence of fences. It may not be extraordinary in the “I climbed Everest” kind of way. But, for us, it’s extraordinary in the “I walk slow enough to see how fences change” kind of...

“…as if refusing to be caught / In any singular vision of my eye / Or in the nets and cages of my thought, / They tower up, shatter, and madden space / With their divergences, are each alone / Swallowed from sight.”— Richard Wilbur, An Event (excerpt) In the last...

  The guidelines of the prompt were very simple. Stories had to be set in a city in the distant future (i.e. in or near the year 2099), be 1,000 words or less, and have as significant plot points both nature and people. With this framework The Nature of Cities launched...

I was vacationing in Florida, taking advantage of Spring Break, and Easter week, writing and reading and escaping the administrivia that accompanies the end of the spring semester when I saw a short report on the television behind the bar at the local pub. It was Notre Dame. It was...

At any one moment, trillions of chemical reactions take place in the human body: a myriad of connections, enzymes, and processes that together make up our human metabolism. You might recognise this concept from health and fitness clickbait headlines that promise things like: “10 easy ways to increase your metabolism”;...

A Brief History of Climate Change Issued in November of 2018 by a collection of 13 government agencies known as the U.S. Global Change Research Program, the environmental assessments of The Fourth National Climate Assessment (NCA4) present a deeply disturbing forecast and polarizing confrontation to most anyone reading the report....

A Tiny Food Forest? As in, an edible forest? At school? Driven and designed by a bunch of 4thgraders? Absolutely. This project became a reality thanks to a dedicated team of enthusiastic individuals (children, teachers, directors, policymakers, nature educators, parents, neighbors, designers, and scientists) in the mid-sized town of Ede...

In 1883, a rooftop garden theatre opened in New York City. The idea was to escape the city summer heat, whilst enjoying some evening entertainment, without actually leaving NYC. A decade later, the New York Times announced that, “New York is fast becoming a city of roof gardens”. In 1935,...

In the last three decades, Copenhagen has shifted from an obscure Nordic capital to a leading global city. It is known for progressive environmental policies, an enviable public transportation and cycling network, and numerous public green spaces, earning it the European Green Capital Award in 2014. Moreover, Denmark is repeatedly...

With a new stream of studies adding to evidence revealing disturbing declines in global populations of insects (Hallmann et al. 2018, Lister & Garcia 2018, Sánchez-Bayo and Wyckhuys 2019) and reports of an ecological catastrophe on the scale of a sixth mass extinction, there is an urgent need to do more...

With an area of just 316 Km2and a population of more than 475,000, Malta is the smallest member country of the European Union (EU). This island state has been moulded through human action since the first recorded human settlement more than 7000 years ago. Today, more than 30 percent of...

It has been raining all afternoon in Megali Sterna, a village in the north of Greece, and, from the empty and closed café we have been sitting in for  hours, it looks like the rain will continue into the evening. We scan the neighborhood for a dry place to pitch...

When we consider planning for green infrastructure, we typically think forward to what kind of city we might imagine for the future. Far less frequently do we consider the history of the city and how past generations have shaped the green spaces and the activities and meanings related to them....

Sustainable cities can be viewed from multiple perspectives. Each perspective can highlight or mute certain aspects, leading us to take different positions on complex issues. Take for example the recent floods in Kerala, the southernmost state of India. Unprecedented rainfall led to intense floods across the state. Over 400 people...

On 14 June 2018, Isabelle Anguelovski participated in the panel Designing, Planning and Paying for Resilience at Rice University Kinder Institute for Urban Research, where she and other leading experts discussed flood mitigation strategies such as low impact design, green infrastructure and urban-scale greenspace preservation, and how they interact with a community’s broader planning efforts....

The 2018 London heatwave lasted weeks! I know we Brits like to talk about the weather—but honestly, it has been really hot—and it’s unheard of to be able to go for weeks without worrying about bringing a cardigan, umbrella, or raincoat when you step outside your door. The parks have...

It’s a hot June day in rural Greece. We stop in a run-down gas station on a small secondary road cutting through wheat fields on both sides. We wipe the sweat from our brows. The gas station attendant opens the refrigerator and pulls out a crate of cherries.  “Take what...

The Ramsar Convention (also known as Convention on Wetlands) is the first of the major intergovernmental convention on biodiversity conservation and wise use. It was signed in 1971, in the City of Ramsar in Iran. This October, the 13th Ramsar Conference of the Parties (COP 13) will take place in...

There is a common refrain in liberal democracies: local government is where participatory action is most likely to happen. Indeed, we often presume that neighbourhoods and towns and cities are privileged—perhaps even natural—spaces for the deliberative coproduction of plans, policies, strategies, and projects for sustainability and the common good. By...

At a recent film screening of our new documentary film Ocean Cities, about connecting cities and marine environments, the panel discussion and questions that followed demonstrated clearly the value of these kinds of films. Some of the comments reflected a sense of being inspired by what other cities were doing...

George Barker, who died on 1 May 2018, will be remembered fondly by all who worked with him. He was a modest man, always full of fun, yet he was one of the most influential figures in the development of urban nature conservation in the UK and was held in...

In recent years, city plans, international organizations, private foundations, and policy discourse more broadly have presented resilience as a necessary characteristic for communities to cope with natural hazards and climate change. Numerous cities around the world are now developing resilience strategies or implementing policies with the stated aim of becoming more resilient. Resilience...

In the last days, with the air finally above the freezing point, and the grey silhouettes of the barren twigs dripping with fine silvery moisture against the faint morning light, I have been drawn into the forest. Every morning, I unlocked the chain securing my bike to a low metal...

“For the child….it is not half as important to know as to feel. If facts are the seeds that later produce knowledge and wisdom, then the emotions and the impressions of the senses are the fertile soil in which the seeds must grow.” —Rachel Carson, 1965, p.58. The natural world...

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 (P3) is dramatically altering Sheffield’s urban forest. The various particulars of the...

Earth’s ecosystems have evolved for millions of years, resulting in diverse and complex biological communities living in balance with their environment (WWF Living Planet Report, 2016). Since the 16th century, human activity has impacted nature in practically every part of the world, wild plants and animals are at risk of...

Ecological gentrification (Dooling, 2009) is a negative social process in which ecological improvements to neighbourhoods lead to gentrification and displacement of the neighbourhood’s original inhabitants. There is an analogous process of ecological gentrification at the level of ecological communities: many vulnerable ecological communities that persist (and in some cases, thrive)...

As yet, there are no smart cities. I read of plenty of people and organisations working hard to create them. However, so far, we have had initiatives, policies, strategies, and some projects, but no examples of cities where it all comes together in a genuinely city-wide way. In addition, most...

A satirical video circulated this past summer announcing Mexico City as the country’s newest and most exciting water park, featuring waterfalls in the metro and an airport runway turned waterway.[1]  I thought they might have included the geyser spouting out of a drain that I saw next to the sign...

Regular readers of TNOC will be familiar with the biophilia hypothesis, which supposes an innate emotional link between humans and the natural world that positively impacts our psychological wellbeing. In other words, we feel most at home in naturalistic surroundings, as this is where we evolved and have spent the...

There is strong interest in the theme of re-naturing cities, since “naturalizing” cities can help address multiple global societal challenges and generate benefits, such as the enhancement of health and well-being, sustainable urbanisation, the provision of ecosystems and their services, and resilience to climate change. But, what are the theories,...

Warning: What follows is entirely personal and non-scientific. This is a good thing. I live and work in a global city. Here’s my justification for being here. I work on scaling up greening in cities across Europe. My global city—London—has been a leader in urban greening initiatives for many years....

In previous TNOC posts I wrote about two apparently different topics: urban agriculture and living underground. Let’s combine them now into a new urban object: Farming underground. You may very well think that I am playing smart-aleck here, and that this paper is just a piece of bravura, since farming...

The first time I visited the Méréville Estate and its Anglo-Chinese garden, created south of Paris at the end of the 18th century, I was struck by the interlinking of nature and culture in this amazing place. This National Heritage Site is the work of the Marquis de Laborde, who...

Urbanization has gone hand-in-hand with agriculture from the beginning. Even in medieval times, when walls and defensive structures left...

Elinor Ostrom’s groundbreaking research established that it is possible to collaboratively manage common pool resources, or commons, for economic and environmental sustainability. She identified the conditions or principles which increase the likelihood of long-term, collective governance of shared resources. Although these principles have been widely studied and applied to a...

A review of “Palm House”, a commissioned project on view at the Edinburgh Art Festival until 27 August 2017. The year is 1880; the place is Edinburgh, Scotland. Edinburgh’s Old Town is internationally known for its squalid conditions; its tenement slums plagued by poor sanitation and overcrowded housing. The medieval...

Some weeks ago my colleagues (from the University of Applied Sciences in Geneva and the City of Lausanne, Nature and City Department) and I organized a half-day event: an exchange of experiences on the Swiss green roof standards practice with the Swiss Society of Engineers and Architects (SIA) in Lausanne....

Recently, Colding and Barthel (2017) critiqued how the Smart City-model is taken more or less as a given good for creating sustainable cities. This view is deeply rooted in seductive visions of the future, where the digital revolution stands as the primary force for change (for a critical perspective, see...

“Do you seek the highest, the greatest? The plant can teach you to do so. What it is without will of its own, that you should be with intent – that’s the point!” —Friedrich Schiller Some days ago, after giving a lecture in a west German city, I arrived back...

Most of us know how “good” trees are for the urban environment, and for the planet overall. Whether you’re a human, an insect, a fungus, a bat, a bird, a four-legged omnivore, or an amphibian, we all love trees. Trees are symbols of health, vitality, and goodness. For the greater...

Through their educational and experimental roles in society, universities can play a unique and vital role in cities’ transitions to sustainability. Although life itself is a learning process and education can happen anywhere, from the streets to virtual places, the temples of educations in our minds were—and still are—schools and...

Greek green roofs—Oikosteges, or OS for short—were born when I discovered that the existing conventional Northern and Central European green roofing systems could not be applied to our situation because they had been designed for the climate and building situations in those countries. Greece has many differences. Greece is in...

In September last year, the IUCN World Conservation Congress—Planet at the Crossroads—brought together in Hawai’i more than 10,000 participants from 180 countries, including top scientists and academics, world leaders and decision makers from governments, civil society, indigenous peoples, and business. It presented a unique opportunity to discuss the unprecedented challenges...

It takes distance to gain a sense of perspective, and so I find myself sitting in a small market town in the north of England looking halfway across the world at my time living in one of the world’s great emerging megacities, Bangkok. From this market town there is a...

The first five people we spoke to in the San Anton neighborhood of the Mexican city of Cuernavaca didn’t know the location of the Salto Chico (small waterfall). The neighborhood’s larger waterfall, referred to as the Salto Grande or Salto San Anton, is known as a place to buy ceramic...

I was looking at an infographic on Twitter recently. It was in the form of a wheel of words, listing dozens of objectives and issues relating to urban design. Hoping that soil, water, vegetation, habitat, or biodiversity would be featured, I looked for some mention of these terms. I did...

We found ourselves scrambling along the slippery, vine-entangled slope, ducking under branches and contorting ourselves around fallen trees. The air was hot and thick with humidity, causing us to sweat after just a few minutes on the trail. As we walked, the noise of the busy highway slowly subsided and...

I read this article by Menno Schilthuizen, a Dutch evolutionary biologist and ecologist, about the evolution of animal and plant species taking place in cities. In cities, evolution is propelled by two forces: the known laws of ecology AND the social dynamics of human society. The article concludes that we...

Sweden, especially its capital, Stockholm, is a very famous “green” city. Indeed, Stockholm’s green infrastructure wedges system is one of the most recognized and cited around the world because of the significant ecosystem services that it provides and because it acts as a source of natural biodiversity for an urban...

Winter is here in the north—not the slightest allusion here to any famous TV series or any recent election, of course. And in the wintertime, life goes underground in a literal sense: tubers and roots reign while most of the aboveground parts of plants are dormant; animals hibernate or at...

In November 2016 there was a celebration in London: it had been 40 years since the idea of creating an Ecology Park in central London was first suggested. The event provided opportunities to share memories of those early days and to see how the concept has taken root and proliferated....

One reason we should care about biodiversity is that it might be the solution to our environmental impact: after 3.8 billion years on planet Earth, Nature certainly has some sustainability and resilience lessons to teach us—that is, before it gets driven mostly to extinction. Will we care to listen? As...

Let’s face the facts. Despite laudable international initiatives for climate change mitigation and environmental preservation [i], major changes in Earth’s balances have been set in motion and we’re starting to experience their consequences: heat records; increased droughts; increased wildfire intensity and frequency; melting of landlocked ice; increased sea level and coastal...

In the summer of 2016, the largest Soviet-era residential area of Estonia was living a new life. The district Lasnamäe, including Estonia’s capital city, Tallinn, was built in the late 70s, but it has fallen into stagnation. Little has changed since its inception, and those big plans are still unfinished....

A review of Tim Ingold‘s lecture event “The Sustainability of Everything” at the Centre for Human Ecology, Pearce Institute, Glasgow, Scotland Sustainability is an overused word. It is much diminished by its occurrence in too many documents purporting to suggest that transport, local government or this tea or those coffee...

The New Urban Agenda, being adopted at Habitat III, requires a coherent and legible global urban scientific community to provide expertise to direct and assess progress on urban sustainability transformations. As we have commented in Nature’s special section on Habitat III, the urban research community is currently institutionally marginalized and...

I live in Stockholm, Sweden. I enjoy talking walks in the autumn, inhaling the scent from degrading debris, kicking around dead leaves, and gazing at the vivid colors. This fall, my baby daughter has often followed me on my walks. Her name is Viola, and she is 4 years old....

“Cities separate us from nature, do they not?” —Light, 2003 No, they don’t; or at least they don’t have to. The good news: green infrastructure is expanding and gradually softening a proportion of our planet’s increasingly urban surface. It appears we’re on the right track, as recent years have witnessed...

Now that urban greening is increasingly seen as a climate adaptation strategy, the question is how to best provide the necessary green space. Where, at which scale, and what type of greenery? Which design is preferred? And how can municipalities increase public support for green adaptation measures? To find answers...

From the very beginning, with the first urban settlements of Mesopotamia around 4500 BC, cities have required a clean water supply and some form of sanitation. As cities grew in size, the water supply tended to be sourced from further afield, with examples of aqueducts bringing clean water great distances...

There is an advertisement that is played with great frequency on television in Dhaka, Bangladesh. Even without the language, the imagery is powerful and vivid; the meaning seems unambiguous. In the setting of a sparklingly clean, modern kitchen, a young pregnant woman goes to drink a glass of what appears...

How do you like roller coaster rides? I love them—provided that I am sitting in the operator’s cabin and not in one of the small, shaken carts frantically moving up and down. In two of my last posts, The Nurtured Golem: A Nantes Neighborhood Transforms Environmental Bad into Good, and...

“Réinventer Paris”, or “Reinventing Paris”, the architectural program initiated by Anne Hildago (the Socialist mayor of the French capital) in autumn 2014 does not lack ambition. When I first heard about it, I was surprised and couldn’t really believe it until spring 2015, when I was convoked by two teams...

Step off the street in Suzhou through a small door and you leave behind the bustling cacophony of a modern Chinese city to enter a different world of tranquility and calm, where natural features create a sense of being surrounded by nature in a tiny oasis that is a scholar’s...

Edward Lorenz’s application of chaos theory to weather forecasting is better known to the general public as “the butterfly effect”, thanks to his conference presentation, “Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas?” Lorenz’s law explains to us that there are unknown and...

Nature is all around us. Plants, animals, soil, air and water inhabit and animate our daily lives, whether you live in the country or in the city. We are invigorated by nature. We are inspired by its creatures, their beauty, and their existential meaning. We depend on nature’s services and...

Jane Jacobs critiqued modernist city planning in the now classic book The Death and Life of Great American Cities (1961). This book is now inspiring an urban renaissance. Jacobs proposed that a city must be understood as a system of organized complexity—in other words, as an ecosystem—and that any intervention...

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...

When Montréal’s Parc Oxygène was bulldozed in June 2014, a local newspaper article aptly spoke of a ‘neighborhood in mourning.’ The narration of its destruction by a neighbor is heart-wrenching (1). This small park in the midst of high rises was an urban oasis made and looked after by its...

A review of the Large Parks in Large Cities conference, Stockholm, 2-4 September 2015. The prognosis for urbanization is challenging—in the next 40 years, urban population will double. Under the growing pressure of modern urban development, large parks are valued by people more than ever. From the beginning of city...

Whilst urbanization has brought many benefits to society, it increasingly denies people of opportunities for the mental, spiritual and physical health benefits from nature. Over the last decade, there has been an alarming global increase in diseases such as heart diseases, cancer, chronic respiratory diseases and diabetes [Note 1]. The...

“We all know the sound of two hands clapping. But what is the sound of one hand clapping?” says a famous Zen Koan. At first consideration, it seems impossible to conjecture about the “just city” without having already in mind what is an “unjust city,” and vice versa. But my opinion is that this...

However complex the urban sustainability question is, the facts are clear to all. Over the next four decades, the global urban population is expected to nearly double, with the vast majority of this happening in Asian and African cities; if we do not rethink and coalesce our approaches and practices,...

 At the end of my last post, Unintended Consequences: When Environmental “Goods” Turn Bad, I raised the idea that sometimes environmental “bads” can also turn good, and that it usually works better when nobody “looks”. I mean that this process works better when the inhabitants take ownership of their living...

Something very significant is happening in London. It’s a plan to make London the world’s first National Park City. Now that’s an idea that could catch on in a very big way. Over the past 18 months, a movement has been growing, drawing together Londoners who want to apply National...

In October 2014, we had a great opportunity to explore different green areas of several Chinese cities within the project “Sustainable green infrastructure in urban-rural areas of China based on eco-civilization,” which was sponsored by the Chinese Government. It was particularly interesting to see different types of greenery that reflects...

Since moving from Edinburgh to London, I have greatly missed my bicycle commute along the former’s Union Canal. There are similar routes in London, but they’re unfortunately not on my way to work. I have always sought out such corridors and they have sometimes influenced my destinations. In response to...

After a hectic start to 2015, I finally managed to slow down the pace. A few days ago, I attempted to catch up on some overdue readings—my way to keep in the loop. Among the many documents piling up on my computer desktop was this short podcast from TNOC: “Closing...

“Stronger than the storm.” I can’t get this phrase out of my head, nearly one week into my sabbatical move to Venice, Italy. It so happens that we arrived on a week when the moon and the winds lined up to create acqua alta (high water) for six days in...

In reviewing the wildlife habitats of British towns and cities for my recent book Nature in Towns and Cities (Harper Collins 2014) I became acutely aware that many of the UK’s most spectacular urban wetlands resulted from industrial activities. The most extensive of these are newly created lakes that formed...

On a Friday night at the end of November 2014, nearly 200 people arrived in the departures zone of Berlin’s former Tempelhof Airport for five hours of presentations, working groups and community-led exhibitions. A projection screen stood on the baggage carousel, and former glass-walled airport offices held bulletin boards and...

Every year, new scientific advances indicate life is more interwoven than we ever imagined. From recent reports that reveal the cascading effects of wolves’ reintroduction to Wyoming to current studies that track the dire impact of Washington dams on the decreasing nutrient loads in Montana forests, evidence builds of a...

Environmental perception by people is complex and dynamic. Individuals are active agents in their perceptions of nature—not passive receivers of information—while the environment is a global unity on which environmental processes within cities are based. Cognitive, interpretive and evaluative components are all incorporated into the perceptual processes of individuals. The...

In the many current discussions about how to make cities more resilient, the potential roles of citizens and urban nature are largely overlooked. There are exceptions, including Krasny and Tidball’s work on civic ecology and that of a number of people associated with the Stockholm Resilience Centre (cf. Andersson, Barthel,...

Green roofs are becoming more popular around the globe and are considered to be a very progressive landscape design devise in urban areas. The green roof has started to become fashionable—it is even considered as one of the “compulsory” sustainable buildings features and an important part of urban green infrastructure....

The swifts have gone. They left about a week ago and the sky is silent over British towns and cities. By now they will be well on their way south, quartering marshes in the south of France and Spain, making for Gibraltar where they cross to Africa; airborne now until...

In my last post, I wrote that efficient urban sustainability policy should be inclusive, in the sense that it should address sustainability in an area large enough to encompass urban centers, but suburban, periurban and dependent rural, or natural places. I called for planners to abandon the “false dichotomy between...

Nearly 70% of the world population lives in urban areas and nearly 75% of economic activity is located therein. Urban areas concentrate not only wealth but also extreme poverty and environmental degradation. Despite the significant progress in urbanization, still a billion people live in the slums of urban areas. Thus...

Next year, the Millennium Development Goals (MDGs), adopted by the United Nations after the Millennium Declaration, are set to expire. The next set of global development goals, which are supposed to be even more environmentally focused — the Sustainable Development Goals — are currently under discussion at the UN and...

Today, we live in the ‘Urban Anthropocene’. This expression combines the global trend towards urbanization and the neologism ‘Anthropocene’, the term an ecologist would be forced to use these days to describe Homo sapiens as the key structuring species that could determine, alone, the fate of Earth’s life forms. For...

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...

Two of the most debated and challenging concepts in urban development are sustainability and resilience. How are they related? Do they mean approximately the same thing or are they distinctly different and can misunderstandings lead to undesired outcomes? In this essay I will try to clarify the concepts, discuss two...

I was lucky to be born in St. Petersburg, Russia, the city of museums and parks.  My first scientific passion was exactly historical imperial gardens.  Traditionally gardens have been seen as very special places, as paradises where people can enjoy sounds of water and birds, can rest their eyes on...

In 2008 the London Natural History Society celebrated its 150th anniversary with a conference on ‘London’s Natural History: past, present and future’. I was asked to consider future prospects. What changes might we expect in London’s natural history in fifty year’s time, and what are the prospects for the Society?...

The world is increasingly urban, interconnected, and changing. If current trends continue, by 2050 the global urban population is estimated to double and be around 6.5 billion. Most of future urban growth is expected to happen in small and medium-sized cities, not in megacities, and approximately 60% of the projected...

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...

Over the past two weeks I have experienced two very different aspects of urban ecology.  The first centered on a pair of peregrine falcons nesting close to where I live in the city of Bath.  The second was a visit to the Olympic Parklands which have been created for the...
