The Revalorization of Urban Nature, for Good and Ill

Many voices. Greener cities. Better cities.

An image of expanding cities is associated, in most people’s minds, with the shrinking and gradual disappearance of urban nature.

The revalorization of urban nature is both an incipient opportunity for change and a potential recipe for disaster.
Yet, as life in cities becomes increasingly stressful and challenging, a gradual revalorization of urban nature is taking place across the cities of the world.

The importance of urban nature is begin redefined with new values: of recreation, relaxation and, ultimately, of possession—private ownership and possession, that is—finding expression in diverse forms.

2. A 'pristine' luxury lake-front home next to polluted Bellandur lakeAdvertisements for real estate developments are a hotspot for the revalorization of urban nature. A quick look at the urban visual landscape of Bangalore—at the eye level of what used to be the treeline, dominated by majestic avenue trees—shows a vast expanse of real estate advertising, much of which is targeted at the wealthy, advertising the sale of apartments and homes that range anywhere from $US 200,000 to over a million dollars.

To differentiate themselves, many projects identify themselves as “green” by using terms such as “pristine,” “lake,” “green” and “woods” prominently, and somewhat indiscriminately. For instance, just next to Bangalore’s extremely polluted Bellandur lake, an advertisement for an apartment complex “iWoods” stands out, somewhat bizarrely juxtaposed with a view of toxic foam overflowing from the lake. Another developer advertises “luxury lake-front green homes” that are “pristine” located near the same polluted lake. The irony of the situation should be obvious, yet these homes sell fast and appreciate in price.

5. A protest by the Sankey Park Walkers Association against a real estate project at an adjacent forest reserveLiving near a well-maintained lake is a luxury for any urban resident. The Kaikondrahalli lake, an oft-cited example of a community-restored and managed lake in Bangalore, organizes an annual lake festival attended by thousands, with children using leaves, flowers and stone art to decorate the area. They enjoy the now unusual experience of observing and listening to the calls of a lake brimming over with coots, moorhens and ducks.

Other lakes, such as the Sankey Lake, promote outdoor exercise with special equipment for senior citizens. Yet the biodiversity and ecological quality of these lakes, which are actively maintained by groups of local residents, are being threatened today by construction in adjacent, ecologically sensitive floodplains and forest reserves. This presents a truly ironic situation: the same construction industry that packages and advertises the presence of urban nature as a resource to be enjoyed by their future residents contributes heavily to the dwindling and disappearance of these resources.

A further step along the evolution of this new urban aesthetic is the complete repackaging of urban nature as a private resource. Thus, new residential communities advertise private butterfly gardens, private streams and even private lakes. Others advertise the exclusivity of locations adjacent to forest reserves. Some claims are frankly bizarre, such as an advertisement that describes an idyllic environment where trees are so happy, “their roots don’t touch the ground.” Readers of these advertisements, meanwhile, are left wondering if the people who create these advertisements have had much practical experience with planting and maintaining trees.

Some would argue that the revalorization of urban nature is a good thing, and perhaps it is, in part. Certainly, if compared to the city aesthetic that the above advertisement portrays, of a baby seeking to live close to shopping malls, I think one can safely assume that we need a renewed public conversation about the importance of nature in cities. I cannot think of an actual baby who would be happier if taken shopping rather than on a lakeside stroll. I would also hope that it is obvious why access to lakes is more important for the well-being of cities and city residents, compared to shopping malls. But the devil is in the details. Who owns this nature? Whose needs does it serve? And will the advertisers who benefit from the real estate value of access to urban nature actually join forces to protect and restore urban ecosystems as public goods?

One path forward, proposed by some planners in Bangalore, is to add a “green tax” to high income residences located around lakes, forest reserves and other public urban ecosystems, ensuring that real estate development contributes to a fund for ecosystem protection. We need a sustained conversation to discuss the feasibility of such measures, looking at the experiences of other cities.

The revalorization of urban nature presents both an incipient opportunity for change and a potential recipe for disaster. We need a renewed, public discussion about these values, even as our developing urban aesthetic needs a ‘reset and reboot’.

On The Nature of Cities

The Rhythms of City Life

Many voices. Greener cities. Better cities.

A friend once told me about the time he started finding dry dog food pellets mysteriously appearing in his pockets every time he put on a freshly laundered and dried pair of pants. Dr. Will Turner had a dog, of course, and recognized the pellets as the same kind he offered his dog in a bowl out on the porch every morning. But he wasn’t in the habit of carrying them around in his own pockets, so how did the pellets end up there, day after day? It took him a few days of detective work to figure out what was going on.

A graduate student of urban ecology, and living in one of the burgeoning cities in the American Southwest, Will was conscientious about his environmental impact. So, among other things, he relied on the desert air to dry his laundry rather than using an electric dryer like too many urban dwellers in these energy hungry western cities. A clothesline in the yard, an oddly oft-forgotten bit of technology, is after all lighter both on the city’s energy supply and a grad student’s wallet. Will’s clothesline stretched across their yard, off the porch with the bowl of dog food.

ScrubJay-PeanutIt took a few days of clothesline- and bird-watching to solve the mystery of the pellets in his pockets. Among the various wild creatures who shared Will’s yard was a Scrub Jay, a consummate city slicker of the not-so-wild American West. This bird, like so many of its Corvid cousins in cities all over the world, is a generalist and opportunist with a not too picky appetite for the veritable smorgasbord served up by us, both purposefully through bird feeders and wastefully when we throw out food and organic garbage. Dog and cat food make for delightful morsels for these omnivores, and it didn’t take long for my friend to notice that his Scrub Jay neighbor regularly pilfered the pellets out of his dog’s bowl on the porch.

Scrub Jays are particularly intelligent, even among Corvids, and have even been shown to be capable of planning for the future. They do this by caching away any extra food tidbits they find, to be eaten later during lean times in the wild. They cache acorns all over their native Oak savannah habitats, for example, digging them up to eat months later during the winter. This ability to cache food, and then to remember the locations of hundreds of cache sites, has evolved as an adaptation to the unpredictable nature of food supplies in their drought-prone semi-arid native country. An experimental study a few years ago found them capable of tracking day-to-day variations in food availability, and caching preferred foods based on what they might (not) get for breakfast the next morning—a form of mental time-travel and planning for the future not seen in too many non-human species. This level of intelligence and opportunistic flexibility of behavior may well be the key to this species’ success in the relatively new cityscapes that have displaced so much of their native habitats.

Will’s Scrub Jay friend had gotten into the habit of not just eating the dog food pellets when hungry, but also hiding them away for potential later use. In the wild, a Scrub Jay caches each acorn carefully, usually in a separate location to minimize the risk of losing them all to potential thieves, parasites, or decay. Seeds may be buried in the ground, or stuck in the crevices of rocks or trees, relatively stable places that are somehow marked down in the Jays’ mental maps for later retrieval. Unsurprisingly, they continue to cache food in the city, finding all kinds of novel hiding places. Such as the pockets of pants hanging on clotheslines conveniently located near bowls of magically refilling dog food pellets. For that was how the pellets were ending up in the pockets of Will’s pants, as he discovered after a few days of yard birdwatching.

Pants, however conveniently they may hang near food sources, can hardly be reliable caching locations. Yet this bird continued to stuff the pellets into the pants, as if driven by sheer habit, even though the cache kept disappearing along with the pants on a daily basis. You can find Scrub Jays use a similarly bewildering variety of odd, unstable locations to cache foods in the suburban jungle. Putting extra food away for a non-rainy day is evidently a habit that has become hardwired into their behavior. Never mind if the cache location itself is ephemeral and unreliable. After all, there is enough food available to these birds in the city that they don’t really depend on their caches so much any more. Caching, then, is rather like how we often put extra food away in the fridge after a big meal, only to throw it away days or weeks later. Who wants to eat leftovers when fresh meals are readily available?

I remember this story, and retell it here, because it illustrates one of the key features of urban habitats for many species: they are relatively predictable habitats offering a reliably steady supply of food. Yes, we build cities by ripping out and paving over more natural habitats, destroying most of the natural food sources for the native creatures. Yes, we shatter the landscape into too many fragments in a patchwork of green/brown/grey which can be transformed over and over at our whims. Yet, amid this increasingly heterogeneous, dynamically patchy space, we do seem to reduce variability in time, establishing new rhythms of renewal of food and water in the urban ecosystems, often to suit our own daily cycles. Any other species that can survive on our excess food subsidies, and find a way to fit into the urban landscape matrix, is free to come along for the ride.

BonnetMacaque-CandyFlossSo what is the ecological rhythm of life in the city, for species that share our urban spaces with us? Dr. Ajith Kumar, one of my professors at the Wildlife Institute of India, while teaching us the methods of documenting and measuring primate behavior in the wild, made the observation that the daily time-budget and diet of monkeys—Bonnet Macaques—in Chennai (and other South Indian cities) consist of hanging around people’s kitchens and eating idli (steamed rice-and-lentil cakes) for breakfast. Just like the human inhabitants of those cities. Nearby, House Crows watch people keenly and dart into kitchens through open windows in sudden snack attacks that startle the human inhabitants but seldom draw more than a frustrated yell or an expertly dodged broom thrown in retaliation. Like their Scrub Jay cousins in California, and other corvids around the world, these Chennai residents have figured out when and where to obtain food reliably in the urban maze.

tea with sparrowsHouse Sparrows in many a quaint European city start their mornings—and likely spend the rest of the day too—hanging around the outdoor tables of streetside cafes, waiting for crumbs of croissant or baguette (maybe bagel for their cousins who’ve settled across the Atlantic) dropped accidentally or on purpose by the patrons. Meanwhile in Tempe. Arizona, in the xeriscaped backyard of Dr. Dave Pearson, an entomologist at Arizona State University, large flocks of birds show up every dawn like clockwork. These mixed flocks include non-native city slickers like the House Sparrow and Inca Dove alongside Sonoran Desert natives like Abert’s Towhee, House Finch, White-Winged Dove, Cactus Wren, and Curve-billed Thrasher. And they all wait patiently (but not for long) every morning for Dave to bring out bags of birdseed to replenish the feeding stations at designated spots throughout his yard.

Sea gulls fly deep inland from the California coast during the winter to survive on urban garbage dumps and roost on the wide lawns of local schoolyards and parks. Alongside migratory and resident geese who honk at passersby, especially in the public parks, aggressively begging for food handouts not unlike the squirrels nearby or the more remote monkeys of southern India. Raccoons and Skunks come out at dusk, patrolling back alleys especially on nights before garbage collection days. Bears too, come rooting through garbage cans, and in some places have found that food supply steady enough through the winters to allow them to give up hibernating altogether. Its a year round party in the city if you know where and how to find it, and aren’t too picky about what you eat.

Gulls-GamlaStan-StockholmExamine the city from an ecological perspective, as an ecosystem built for humans, and a few features about the rhythm of city life stand out. We built cities to escape the vagaries of nature, its seasonal cycles and annual and decadal fluctuations which make life challenging. In the city, we shelter from extremes of climatic cycles, insulating ourselves in increasingly climate-controlled indoor environments. Outdoors, cities even create their own local climate bubbles, heat islands which mitigate the northern winters and herald a globally warmed up future. We have now altered the flow of food and water across the planet, funneling much of the products of plant/animal/human labor into cities that blanket the lands as busy hubs in an ever tightening web of highways and railways. Our network of cities in this globalized world is thus the culmination of our millenia-long quest to free ourselves from the contraints of nature’s cycles. So we can now eat mangos and cherries in the middle of a northern winter, and never seem to be too far away from an all-you-can-eat buffet of foods fast and slow. In harvesting so much of the Earth’s primary productivity for ourselves, we have succeeded in raising and flattening out the fluctuations in natural cycles of nutrient flows. Where our ancestors (and some increasingly small indigenous communities even now) flowed across the landscape keeping a close eye on the flushing of leaves, blooming of flowers, ripening of fruits, and the local or long-distance migrations of fish and bird and mammal, worrying about where the next meal was coming from, we now mostly worry about when the bakery around the corner opens in the morning so we can get in line before the fresh bagels are sold out. The ebbs and flows in our food supplies have been replaced by a more steady stream, and the rhythm of food availability now pulses to a new urban beat, set more by the convenience of our social arrangements rather than the rotations of the planet or its cycling around the sun.

While we bask in this triumph… yes, I know, it is hardly an unmitigated triumph given the litany of environmental damage in its wake as often documented on this very blog; and I know that this steady flow of food and resources is not equally available to all humans even in the cities let alone outside; but, despite those persistent knotty problems, we have nevertheless triumphed over nature’s vagaries in large parts, uneven and ephemeral as our triumph may turn out to be. So… while we bask in this triumph, it shouldn’t surprise us to notice that many other species have also been watching our success and have been riding our tailcoats into the new Anthropocene Earth. It shouldn’t surprise us that the list of species hopping on to our urban gravy train is still growing, as more species respond to the changes wrought by global urbanization, and succumb to the evolutionary challenge of adapt or go extinct.

In the wild, successful species must evolve finely-tuned physiologies that track the regular beat of the seasons and the pulses of tropical storms and the less regular longer rhythm of El Niño cycles which shape the availability of water and food. So the wildflowers and cactuses of the Sonoran Desert or the Namib wait for the unpredictable “monsoon” winds to bring rain which triggers quite an immediate dance of life that ripples quickly across these desert ecosystems. And so the bears and the frogs hibernate through temperate winters while herds of large mammals (used to, still try to) flow across Alaska and Africa, and the birds fly across oceans and mountains, chasing seasonal peaks of sunshine and rain captured by plants and turned into food cascading through complex food webs. Once we began to figure out these nutrient flows, however, and learned to capture and control and divert the planet’s primary productivity to ourselves, we inevitably drove many other species, our competitors and predators, to extinction locally and globally. In the process, we also changed the pressures of natural selection acting on these species. Those species that didn’t go extinct began to evolve adaptations allowing them to fall through the cracks into our own habitats which we don’t really control as well as we think we do. Extinction, while inevitable, is only one of two choices every species must face in life. The other option is to adapt, and many species have and are adapting to the rhythms of urban life.

Evolutionary consequences of our action are, if you think about it, quite inevitable. Set up feeders in your suburban yards to feed the poor birds starving through an English winter, and don’t be surprised if some of those birds change their migratory behavior and begin to split into new species. Such is the tale of the European Blackcap Warblers, which evolved to exploit the continent’s spring flush of insects and fruits to raise broods in the summer before heading south to warmer climes in the winter. When bird fanciers in England and Ireland started setting up bird-feeders, a few of the Blackcaps found they didn’t need to undertake the arduous risky migration towards Africa after all; much easier to hang out in the British gardens where the bipedal primates with the funny hats keep up an endless supply of bird food. That way, not only does a warbler have a better chance of surviving over-winter, it can also be among the first to fly back to its nearby German breeding ground and be in prime position to make the most of the continental summer. The longer-distance migrants arrive later, and must mate among themselves. Thus a few individuals who perhaps flew the wrong way, and who might in the past have simply died in the winter, have now grown into a distinct population thanks to the predictable generosity of human bird feeders. Since migratory behavior, including direction of migration, and choice of mating partners, are all part of the genetic legacy passed from parent to offspring in these birds, the European Blackcaps are now well on their way to splitting up into two distinct species: the German traditionalists who continue to migrate south, to Mediterranean villas or African woodlands for the winter, versus modern urbanists who simply hop across the channel into English and Irish gardens. The new rhythms we have introduced into the cycles of nature sure can alter the age-old evolutionary dance.

Ask humans about the rhythm of city life, however, and they will tell you it is not the same everywhere. New Yorkers, Mumbaikars, Londoners, and Edokkos (or Tokyokkos) have a faster cadence to their walk to the subway stations, and get impatient if their coffee is not served fairly quickly, while Kolkatans and Parisians prefer to linger in their coffee houses, and the lazy beach bums of Los Angeles and Rio de Janeiro lounge in the sun and sand. These rhythms turn out to be more than mere cultural stereotypes. My Fresno State colleague, the psychologist Dr. Bob Levine, who studied the geography of psychological time across human cultures, measured how fast people walk in different cities and found that walking speed correlates quite well with these cultural stereotypes. More recently, physicists Geoffrey West and Luis Bettencourt of the Santa Fe Institute took a big data approach to document the social, economic, cultural and energy metabolism of cities worldwide, and also found patterns confirming the cultural stereotypes: there are indeed fast cities and slow cities, their different rhythms seemingly driven as much by population density and economic activity as by cultural practices and preferences. While many cities aspire to the faster trajectories of the more conventionally successful metropolises, others, like in Italy, are banding together in a new Slow Cities campaign to augment the Slow Food movement.

What does this cultural variation in the rhythms of city life, urban metabolism, mean for other species that are adapting to our habitats? We are only just beginning to appreciate, measure, and understand the evolutionary adaptations of the slowly growing list of species that constitute our urban wildlife. As I described above, the overarching trend of steadying food and water supplies to make them predictably available year round is allowing many species to adapt to our perennial smorsgasbord. Yet, in the finer details, these adaptations must also be tuned to the culturally driven rhythms of who puts out food for birds or monkeys when and where, how and how often garbage is collected and disposed off in different cities, and whether people in desert cities can stop growing lawns to plant more water wise gardens.

Having passed a rubicon recently by having a majority of humans living in cities, are we now also on the threshold of another profound planetary change where human culture sets the dominant beat defining the natural rhythms of food availability for other creatures? Or have we already passed that threshold too, obliviously? In the recent alarming declines of House Sparrows in Eurasia, we are already seeing the consequences of rapid technological and cultural changes, which can destabilize even our most seasoned companion species. In drawing other species into the vortex of urbanization with our predictable food subsidies, are we setting up more of them for longer-term evolutionary failures? Or can we learn quickly from their successful adaptations and figure out how to enjoy the benefits of a culturally diverse city life which also includes a fair bit of biological diversity?

The answers to these questions lie in our own cultural adaptability and flexibility. We have the ability to develop this new understanding of the evolution of species in urban environments, and harness it towards improving the quality of life for all species concerned. We also have the capacity to carry on blindly with ingrained cultural habits, much like the Scrub Jay stuffing dog food into pants pockets without realizing the futility of that caching effort. The answers to these questions, and how quickly we find them, could be keys to how the music of urbanization unfolds across our planet, into a life-sustaining harmony or a cacophonous crescendo that either slows down or accelerates the pace of the sixth mega-extinction we are now wreaking in the history of life on Earth.

The Rise of Resilience: Linking Resilience and Sustainability in City Planning

Many voices. Greener cities. Better cities.

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.

The rise of resilience

Resilience as a planning and managing priority for cities is on a meteoric rise with NGOs, governments, planners, managers, architects, designers, social scientists, ecologists, and engineers taking up the resilience agenda. The rise of resilience is evidenced by the most recent resilience conference. In May 2014 the Resilience Alliance hosted Resilience 2014, in Montpellier, France. With over 900 attendees, the diversity of topics presented by researchers was overwhelming. If you only look at the Twitter activity under the hashtag #Resilience2014 you can see how the research community is grappling with concepts that vary from social justice, to planetary boundaries, to unsustainability. (Most of the presentations are already online, so feel free to catch up on this discussion).

Resilience is now being bantered around as sustainability has been for more than a decade, which is to say with little meaning and often as a label to fit conveniently on top of pre-existing agendas. In fact, some argue that resilience has already replaced sustainability as the main concept in the urban discourse. A recent op-ed in the New York Times filed shortly after Superstorm Sandy described this new wave of resilience thinking as forming major agenda setting in the United States. But what is urban resilience, and how does it relate to sustainability? In recent discussions I’ve had with city planners, government officials, natural resource managers, researchers, and practitioners it is clear that what resilience means is definitely unclear.

Resilience and sustainability

The large overlap in the meaning of the resilience and sustainability threatens to make both concepts weak. I fear we are quickly losing hold of the specificity of these influential concepts, and therefore the power of the resilience approach to improve human wellbeing in urban contexts. Other scholarshave begun voicing similar concerns.

I came away from the Resilience2014 conference with the realization that we still have serious work to do to understand how all this research and discussion on the benefits of urban nature and ecosystem services relate to the rapid rise of resilience planning, resilience design, and resilient cities initiatives. I’ve discussed the utility of resilience theory for understanding complex systems previously in this space, but see also other contributors that have also discussed the relationship between resilience and sustainability (see Maddox, Sanderson, Mancebo and Elmqvist for examples).

Defining resilience

More often than not resilience is still mostly discussed as “bouncing back” from a disturbance. For example, in the New York City post-Sandy resilience report, “A Stronger, More Resilient New York from the NYC Special Initiative for Rebuilding and Resiliency, the focus is very much on rebuilding and recovery, a particular engineering resilience perspective. This is not unique to New York, but is quite common in many other cities around the world. However, the current, more ecological concept of resilience is not only about bouncing back and recovery but also about the ability to adapt, often discussed as adaptive capacity. In this context resilience is the capacity of a system to experience shocks while retaining function, structure, feedbacks and, therefore, identity.

Definition of sustainability and resilience concepts (after Folke et al. 2010 and Tuvendal and Elmqvist 2012)
Definition of sustainability and resilience concepts (after Folke et al. 2010 and Tuvendal and Elmqvist 2012)

If you buy the idea that we need to be building social-ecological resilience, then city planning still has a long way to go towards definition or understanding of social-ecological resilience that moves beyond recovery and rebuilding following disturbance. Additionally, resilience needs to be linked to sustainability so that the resilience we are trying to plan and design for actually helps us move towards desired future sustainable systems states, and not undesirable ones. Current resilience planning and management efforts may just as likely be locking our urban systems into undesirable trajectories, away from sustainability.

For example, after Superstorm Sandy hit New York City and the New Jersey coastline, there was much discussion about large technical infrastructure solutions for dealing with expected future storm surge and coastal flooding: for example, closeable sea gates at the narrow section of the entrance to New York harbor. But the sea gates proposed to deal with these serious threats to the social-ecological system of New York, if implemented, could lock the city into energetically, resource, and economically unsustainable long-term maintenance costs that also have serious ecological side effects.

Sea gate proposed in the report, “A Stronger, More Resilient New York” from the NYC Special Initiative for Rebuilding and Resiliency
Sea gate proposed in the report, “A Stronger, More Resilient New York” from the NYC Special Initiative for Rebuilding and Resiliency

Spurred by the recognition that we have to plan and design ways to avoid the level of devastation that Superstorm Sandy inflicted on the New York City region when faced with future storms, the Rebuild by Design program was initiated to articulate visions for climate change resilience in the New York City region. The fundamental idea of “rebuilding” is not necessarily antithetical to resilience, but it underlines the focus within governments at national and more local levels to think about resilience to extreme events from a primarily technical and infrastructural level. To be fair, improving social-ecological resilience is difficult, and when thinking about a very large and complex system like New York City, we can forgive some path dependency, or inertia, in the discourse and design innovations. Still, we have to remain vigilant about the way we use resilience as a concept and a planning and management priority lest our best intentions lead us towards more unsustainable futures, despite perhaps achieving some measure of “resilience”.

Resilience of what? To what? And for whom?

Resilience is understood as the ability to adhere to or lock-in a specific pathway. The generalizability of this concept means it can be applied in multiple kinds of systems. It also means that resilience can both help us achieve desired future states, as well as lock institutions, political structures, ecosystems, or cities into undesired, unsustainable system states. For example, though we rarely read about it in our scientific discourse, corruption and organized crime are incredibly resilient, and yet most would agree are not part of our visions for sustainable futures.

At the same time, given the often enormous inequities in our cities, we need to be thinking about resilient of what, to what, and perhaps especially, for whom? For example, though the installation of a sea gate in the New York harbor might improve resilience to storm surge and flooding for some Manhattan and Brooklyn residents, it could have negative effects in other areas, such as decreasing resilience for residents and ecosystems in Staten Island, New Jersey, or Long Island. Urban resilience planning and management has to take seriously a combined social-ecological perspective so that outcomes contribute to equity, as well as human well-being and ecological integrity.

Dense urbanity?

Sustainable city initiatives are often those that maximize efficiency, minimize energy, and reduce redundancy and material use. Yet, redundancy is one of the hallmarks of a resilience system. Sustainability goals and resilience goals, if not examined carefully can be completely at odds with each other.

One conundrum that scholars and planners have not taken seriously is the problem of urban density. In the sustainability discourse dense urban centers are the key to a sustainable future, and yet, the more dense our urban settlements, the more socially and economically vulnerable they may be to disturbance whether it is coastal flooding, disease outbreaks, political unrest, or economic disturbances. The tight connectivity within dense urban systems — dense in population, but also infrastructure, social ties, and biogeochemical and economic flows — can contribute to resilience, or increase vulnerability. We must be careful not to assume density is positive or negative, but carefully consider, probably on a case-by-case basis, how urban planning, governance, and management for both resilience and sustainable futures can ensure resilience goals that overlap and support sustainability goals.

Harnessing resilience

Understanding urban resilience and urban sustainability as two concepts that promote a plurality and diversity of solutions to social-ecological problems implies that urban planning needs to take on-board yet new metaphors and paradigms to further transform cities (Wilkinson 2012). Resilience can reinforce both sustainable and unsustainable developmental pathways. Harnessing resilience to reinforce system dynamics that promote sustainability is key to achieving future desired sustainability states.

Coda: if you want to get involved

Resilience researchers Gary Peterson and Daniel Ospina are asking for the resilience research community to participate in defining the important questions for the next wave of resilience research. They have created a Google based survey to ask a broad community of researchers and practitioners interested in resilience what research areas they believe are key for advancing resilience research. You can participate in the forum by clicking here. Additionally, the Resilience Alliance is launching a new resilience online network in fall 2014. You can find out more information here.

The Rivers Have Called Upon Us

Many voices. Greener cities. Better cities.

As I was reading Musagetes’ Manifesto on Economic Dignity and getting all passionate about activism, the usual disturbing and stressful noise from the construction of a new ferry pier next to the construction site of another huge tower on the East River in New York City started up. The new pier will transport thousands of people back and forth, swarming between Williamsburg, Brooklyn and Manhattan since Hurricane Sandy damaged part of the L train tunnel normally servicing this route.

The noise of machines points to environmental destruction worldwide. Can we make enough counter-noise in a call to action?
I thought about the banging noise, its quality signifying the violent jamming of poles into the riverbed, and how our endless attempts at controlling our environment have led to such an unstable one. Four years ago, Hurricane Sandy upended part of the boardwalk close to the pier, and there is still a massive hole fenced off to the public. This river is fighting back, I thought; I’m not alone in sharing this idea.

“The Rivers Have Called Upon Us” is a beautiful Berta Caceres quote used by her indigenous activist organization Council of Popular and Indigenous Organizations of Honduras (COPINH) to protest a proposed dam supported by the Honduran Government, which was once backed by China, the U.S., and the Netherlands. When she was murdered by government thugs, those countries pulled out of the deal. Protests in Washington, DC put a stop to USAid funding to Honduras, and therefore, “inadvertently” funding a criminal government.

The banging noise continues through my reading of stories of environmental devastation by global corporations and the poor, disenfranchised and mostly indigenous people affected who are standing up to what seems like an unstoppable force, all over Tibet, all over Peru, and all over Honduras. That’s only three countries, but really all you have to do is point your finger at the map, pick a country and Google it for “environmental destruction,” and you’ll find lists of stories.

When traveling in Peru last year, I had a long conversation with an old man who runs tours of Lake Titicaca. He told me stories of the gold rush happening there, and that many Canadian miners go to the Amazon, pay off local government officials, and start mining illegally. I was surprised and disgusted with my country. I hadn’t heard of this story but Canadian mining companies are everywhere, including Peru and Tibet, and leaving devastation in their wake. It’s very easy to destroy someone else’s land when you are not the one that has to live there. We saw this in British Columbia, where I grew up, when U.S. mining companies could suddenly and easily cross the border because of the NAFTA Agreement and mine our mountains, leaving toxic waste running into our ocean. But how far will these corporations go? Will they continue to support a government regime that is killing its citizens just to get their gold? Yes, it seems so, unless this news gains international attention like the Berta Caceres case.

So there is only one thing to do. The noise of machines is worldwide. We must make noise worldwide to silence it and to protect what is our lives, our survival and our sanity!

The Role of Cities in the Climate Fight—A Cautious Approach

Many voices. Greener cities. Better cities.

Cities are helping lead the global effort

Cities are the new face of climate change. Where I live in New Haven, Connecticut (USA), we are witnessing its impacts—warmer winters, sea level rise, and inland and coastal flooding. The city is taking steps to address climate change, including adding bike lanes and adapting to future vulnerabilities. These measures to create climate solutions are not unique—hundreds of cities across the planet are assessing their own vulnerabilities to climate impacts and designing solutions that reflect and respond to local conditions. Climate change has emerged as a local issue that requires local solutions.

Cities have emerged as key partners in the fight against climate change, but their impact goes beyond the numbers.
It hasn’t happened overnight, but today more and more cities have signaled their support for climate action. The first international climate agreement, the 1997 Kyoto Protocol, received relatively weak support with signatories from only 84 countries. Although cities could not ratify the Protocol, many indicated their support by signing on to a parallel Mayors Climate Protection Agreement in the years following the Kyoto ratification. The groundswell of municipal climate efforts expanded dramatically between 2005 and 2015, indicating that municipalities have advanced climate change policies despite—or perhaps because of—the intractability of international and federal challenges. In fact, the outpouring of support from cities, combined with a bottom-up framework, helped steer the success of the Paris Agreement, the 2015 landmark climate deal which was signed by nearly 200 nations.

In the U.S., the first few months of Trump’s presidency have been characterized by reversing or abandoning federal climate policies altogether. Measures to reduce fugitive methane emissions, standards to improve fuel economy of cars and trucks, and the Clean Power Plan all headed for the chopping block. The Keystone XL pipeline was approved and federal lands and waters were opened to new oil and gas drilling. But the importance of cities reached a tipping point in late May when Trump announced that the U.S. would pull out of the Paris Agreement. This announcement was met with strong and swift repudiation of the President’s actions – cities responded with new municipal climate commitments and mayors denounced the withdrawal from the international climate agreement. Cities like Pittsburgh have committed to 100% renewable energy, and more than 230 cities recently pledged to support the Paris climate targets.

Cities have emerged as key actors in the fight against climate change, but it is worth an investigation to understand the extent to which cities are helping meet international emissions targets. Does city climate action lead to substantial emissions reductions, and if not, why? What is the real importance that cities have in meeting global emissions reductions targets?

Progress at the city level

Cities are helping make progress to meet international targets. Cities are measuring their emissions, setting targets, implementing measures to reduce emissions, and joining pledges and pacts (such as the Compact of Mayors). Many cities are setting goals for 2050 and beyond, signaling a commitment to long-term investments in infrastructure and technology that can shape low-carbon development. Many of these targets are in line with international climate mitigation and adaptation commitments. Cities are installing solar panels, building bike lanes, expanding energy efficiency programs, incentivizing public transit, and supporting electric vehicles. These measures have real impacts on reducing a city’s emissions, as well as reducing global climate emissions. Local policies have an impact on the global level.

Although estimates vary based on today’s pledges, it is expected that urban climate policies will avoid between one and three gigatons (Gt) of carbon dioxide (CO2) emissions by 2020. These avoided emissions are the equivalent of shutting down between 300 and 900 coal-fired power plants for one year.

Challenges for city action to deliver international targets

Even with the heightened focus on municipal-level climate action we are still a long way from meeting global emissions reductions targets. Annual carbon emissions were around 49 GtCO2 in 2010, and there is a large gap between what cities can directly reduce and what is needed to meet Paris climate targets. Not all of these emissions contribute to global warming as some is absorbed in carbon sinks (e.g., oceans, forests), but the municipal emissions avoided are too small —federal action will still be needed to meet global emissions reductions targets. Cities alone are not the silver bullet to keep climate change in check.

Some of this discrepancy between a city’s apparent best effort to reduce emissions and the actual policy results are inherent limitations in what cities can achieve. Despite cities’ attempts to address climate change—be it adaptation or mitigation—they are bounded in their abilities to implement climate policies by existing legal constraints, a city’s development trajectory, and available resources or capacity. The legal constraints of the policies available to cities can restrict the policy levers available for local governments. The existing infrastructure and urban development trajectory determine the opportunities for implementation of low-carbon strategies. The existing resources available to a municipal government—from financial to technical expertise—determines the extent to which urban areas are able to implement climate policy.

Existing local government law is the overarching political lens through which we can understand municipal climate policies. Cities do not have a free license to drive policy innovation and adoption. There are constraints on what a city can accomplish or implement based on the constitutional authority or policymaking power afforded by a state. Local government law is created by national governments (such as in the UK or South Africa) or by subnational governments (e.g., the states in the United States). The legal mechanisms established by national or subnational governments determine the legal aspects of how a city operates, including city governance structures, fiscal authority, land use regulatory structures, and city boundaries. As a result, the extent to which self-determination can occur at the city level is constrained in large part by the capacities and requirements set by the federal or subnational governments. For example, even though a city may wish to install a bus rapid transit system, it may not have the regulatory authority to do so—that authority may lie with a different government entity such as a regional transportation agency.

The second limitation is the existing built environment and development patterns, which set in motion the opportunities and challenges that a city may face as climate policy is developed. Cities have very different emissions trajectories shaped by a range of factors, including heating degree days, economic activity, population density, power generation, technology, transport energy consumption, and urban form. In cities, energy use (and therefore emissions) generally increases with increasing economic activity for cities with less than $10,000 gross domestic product (GDP) per capita. Energy use increases more slowly for cities with GDP per capita above $30,000 USD—many of which are countries belonging to the Organisation for Economic Co-operation and Development. If a city is developing with relatively little infrastructure lock-in, rapid development presents more opportunities to encourage a low-carbon development pathway – construction of compact mixed use housing, connectivity through multimodal transportation options, and low-carbon building materials (such as timber-frame high rises). For mature cities, low-carbon policy options may be blocked by inertia of the existing infrastructure. Generally, cities in more developed countries are further along this urban emissions pathway.

The last constraint is the available resources—from financial resources to technical expertise. Cities are faced with many competing priorities, and climate change does not often register as a key priority. Although this is changing, there are many reasons for this—climate change is characterized by delayed effects, dispersed impacts and weak governance resulting in policies that “discount the future irrationally.” Even cities in California—a relatively financially stable state with a progressive climate agenda—may not meet some of their climate goals because of a lack of adequate resource capacity.

City action is Important for climate change

Even though there are many challenges at the city level, more and more cities are stepping up to the plate to reduce emissions. Cities that have already begun are forging ahead with measures to reduce emissions.

Cities are truly labs of experimentation; they are sources of innovation and inspiration for policy development that is not politically feasible at other levels of government. Cities can demonstrate that a given climate policy is successful, and can encourage implementation in other cities or the scaling up of that policy at other levels of government. The flexibility and nimbleness, often because there is less bureaucracy at the city level, represents an important component to scale up successes to the subnational, national, and international scales.

Another key part of climate policy is that they can create a multitude of co-benefits. Co-benefits are additional benefits that are realized through a given climate policy, that are above and beyond the direct benefits of emissions reductions. These co-benefits can be particularly important selling points in messaging a given policy, allowing the climate mitigation to be communicated as an associated or additional benefit.  Local governments respond heavily to these demand-side factors. Co-benefits can include green jobs, improved air quality, reduced traffic congestion, and economic development. Green jobs, such as in solar and wind, represent important employment opportunities. Improved air quality or alleviation of congestion result from policy co-benefits associated with transportation emissions. For example, bus rapid transit can provide reductions in emissions as well as alleviate poor traffic conditions and improve local air quality. The financial co-benefits associated with climate action can also be seen as part of a strategy to develop a competitive advantage over other neighboring cities. Policies in a municipality to support renewable energy may lead to the relocation or expansion of renewable energy companies. This helps create a competitive advantage, and accelerates and diversifies the city’s economic development.

Cities move us forward

Cities represent a huge opportunity to mitigate climate change, and there are many openings to use the policies implemented at a local scale to contribute to national or international progress on this wicked problem. Furthermore, cities also represent a groundswell of action that has driven support for international engagement, including the Paris Agreement. The opportunities presented by climate policies in New Haven are many—the city is creating a better quality of life by encouraging biking and walking options, helping residents save money on heating bills by supporting building retrofits, and protecting residents from the financial impacts of flooding and sea level rise. The city’s leadership on climate change can help drive more aggressive action at the state level, creating a positive feedback loop and momentum to support climate policies in other Connecticut cities. Even though New Haven’s climate policies may not make the difference in limiting warming to 1.5oC, the city’s support brings home the concept that climate change is a local issue with local solutions.

The key challenge is that there is only so much that cities can do without top-down action. Cities still need the support from states and national governments to achieve the emissions reductions in line with the Paris climate targets. Because of the nature of local government law, there are limitations on what a city can implement without regulatory approval from a state or national government. Ambitions are unfortunately tempered by legal and regulatory structures. The existing infrastructure and emissions trajectory in a city delineates the extent of policy options are available. And, a city may not have the resources available to implement a desired climate policy. While cities are important to reducing emissions, they are not able to do it alone.

Within the U.S., some of the greatest opportunities to reduce emissions are not at the city scale. Retiring coal fired power plants and strengthening vehicle emission standards are two policies that have the greatest potential to drastically reduce emissions. And, there is not much that cities can do to make sure that those policies are in place. However, in aggregate, city reduction strategies do represent a significant opportunity to stay on track to meet our climate targets and limit the impact of Trump’s withdrawal from Paris.

In today’s landscape, we are looking to cities to scale and amplify the momentum that has already been exhibited thus far. Signing a pledge is an important first step—but it is just the beginning. Current municipal initiatives are not enough to meet international targets. But leveraging available resources, inspiring creativity, and bringing citizens together can hopefully foster the ambition needed. It also may require acknowledgement that although cities are important for many reasons—a key contribution to meeting the climate challenge may not be through emissions reductions, but rather driving the international agenda and setting in motion the measures to reduce emissions, such that when state or national action comes along, it is that much easier to do.

The Royal Bats of Kano City

Many voices. Greener cities. Better cities.

Out of the 17 UN Sustainable Development Goals, SDG 11 is a standalone goal for urban sustainability, with defined targets and indicators. SDG 11 can help urban policy and decision-makers and local people to think about and work towards urban sustainability. Most cities in developing countries, including in Africa, lack capacity for effective urban planning, a shortcoming which, in part, leads to a failure to protect urban biodiversity amidst the challenges of rapid urbanisation.

The story of the royal bats of Kano city represents the key challenges of urban environmental sustainability in developing countries.
As such, it is important to look at how informal institutions, such as local beliefs and socio-historic agreed-upon behaviours on the sacredness and powers of gardens, help in protecting and conserving the threatened urban biodiversity in African cities. Looking at the role of indigenous knowledge and the values that indigenous people accord to the gardens is important, particularly because most of the formal institutions saddled with such responsibilities fail in delivering their mandates in many cities of developing countries. The case of rapid urbanisation in Kano city and its periphery, its impact on open and green spaces, and the role of institutions is documented in some studies, such as Barau et al. (2013, 2015).

Here I’ll discuss the survival of bats in an intensively urbanised Kano city and its periphery. This discussion supports arguments made by Mark Hostetler in his recent post about the value of conserving forest fragments and individual trees in urban areas. In that article, he suggests that forest fragments and individual trees render some supportive services for migratory birds. In this context, looking at the role of Kano Emir’s palace will provide key insights into what fragments or remnants of green areas can do in supporting biodiversity in densely urbanised cities. Kano city and its surrounding urban areas, with an estimated population of about 3-4 million inhabitants, constitute the largest urban area in Northern Nigeria. The ancient city of Kano dates from the late 10th century, and the city’s walled perimeter covers an area of 29 km2.

The Kano palace, also called Gidan Rumfa, was built by King Muhammadu Rumfa between 1479 and 1482. Since that time, it has remained the largest traditional palace in Sub-Saharan Africa (Nast 1996), as well as the oldest and continuous seat of traditional authority in Nigeria. The Kano palace has attracted the interests of many researchers and visiting heads of state and governments, including the Queen of England, the U.S. President, the British Prime Minister, and HRH Charles, the Prince of Wales. Compared to an average home in Kano city, the Kano Palace covers an area of approximately 14 ha and is surrounded by walls of 6–9 m. high outside and, on average, 5 m high within the palace complex. The high walls of the palace surround the royal gardens (sheka, in Hausa language). The western garden has a length of 325 m and an average width of 85 m., while the eastern garden has an approximate length of 370 m and an average width of 45 m. The two gardens constitute about 45 percent of the total palace land area; the built area covers roughly 30 percent of the palace, while the open spaces represent about 25 percent of the total palace land area. The residents of Kano city have always considered the Kano palace as a city within a city by virtue of its size, spatial patterns, and organisation of space. In the context of urban sustainability indicators, including SDG Goal 11 and the Singapore Index, the proportion of green and open spaces makes this intra-city extremely favourable for sustainability.

Compared to the extremely dense and dry parts of Kano city, the Kano palace gardens provide a sanctuary for birds and some fauna, and possibly for migrating birds and insects as well. The palace also provides refugia to bats—chiroptera. A number of studies have investigated the effects of urbanisation on bats species, which ranges from loss of habitat and fragmentation to pollution. Most previous studies and this author’s experiences with Kano city have indicated a notable decline in urban biodiversity due to the progressive decline of green and open spaces. Less birds are observable on the ground and in the skies—not so for bats. In 2010, I conducted some studies inside the gardens of Kano palace, where I observed thousands of bats that flew and roved in the skies of the palace simply because of my perceived movements and the movements of the people following me. The gardens are about the only sanctuaries where the bats are left undisturbed; now they have become dominant species in the relatively undisturbed palace gardens and, in this way, they have become royal bats!

It is widely assumed that the palace gardens are as old as the palace itself (which was built in the 15th century). I want to believe that the bats offer some notable and yet unexamined ecosystem services in the palace and the city at large. Ecologists suggest that insect-eating bats help in controlling disease vectors, while fruit-eating bats help in fertilising soils with their guano and in dispersing seeds for flower pollination and forest regeneration. For the people around the palace and the people residing in the palace, the take-off time of the royal bats is a fascinating sight. And for the palace itself, the bats help maintain its security: any unusual movement in its gardens triggers movement of the bats, which alerts everyone in the palace. Bats really prefer places with minimal human movement and disturbances. This is understandable in the case of the royal bats; once, I saw helicopters hovering over the garden when the Nigerian President was visiting the palace. The noise of the hovering helicopters caused the bats to fly in the early afternoon hours.

While the Kano Palace has provided safe living spaces to thousands of birds for such a long time, it is thrilling to see the bats when they depart the palace in the late afternoon or early evening to search for foraging spaces mostly outside the old city, where different species of fruit bearing trees and ponds can be found. It is interesting to observe the bats while they fly out in chorus from the palace almost at the same time but in different directions—directions most probably dictated by needs for food, water, or something else.

Although, the old city is massively urbanised, two to three kilometres north of the palace is the greener and planned section of urban Kano. This area once housed colonial and corporate residential areas and has been able to maintain some old trees, including local and exotic species. Hence, it is easy to see some of the bats making an early descent in this area, probably to access fruit bearing trees. South of the palace and outside the city walls, there are remnants of ponds around the disappearing city walls and clusters of trees located within the perimeters of the Kano zoological and botanical gardens, as well as clusters of trees found in the industrial areas. The western and northern parts of the palace are the oldest and most densely peopled parts of the city. However, as the bats move farther west, they find institutional buildings: schools and university campuses that keep some trees. It is obvious that some bats fly at higher altitudes and may be moving to far away distances into farmed parklands in the urban periphery.

Bats are nocturnal mammals; this life history trait works well for them as it reduces competition with birds at water and feeding spots. Indeed, the royal bats of Kano city owe their continued existence in this intensively urbanised city to the continuous existence of the Kano palace gardens. The bats may not survive in other fragments of green spaces in the city because they are too exposed to humans and other species.

The story of the royal bats of Kano city represents the key challenges of urban environmental sustainability in developing countries. In many African countries, urban planning professionals and agencies have lost track of what to do or how to go about the business of greening congested cities. However, based on the example of the situation in Kano, it is obvious that small pockets of green areas can play a tremendous role in securing biodiversity. Importantly, indigenous institutions play an even greater role in this context. Indeed, the ability of the Kano palace to maintain its greenery for centuries is of great interest to contemporary urban sustainability.

It does not take specific budgetary allocations to maintain the royal bats, since that comes as part of the costs of maintaining the palace gardens. Although the gardens are exclusively for the use of the Emir of Kano and his closest family members, the preservation of the gardens through generations and dynasties is amazing. I am of the opinion that public conservation organisations should consider the use of the concept of payments for ecosystem services, which, in this case, should entail making some funds available to the palace as a compensation for keeping the gardens so that they are maintained as a base or sanctuary for biodiversity conservation in a rapidly and intensively urbanising city. Indeed, there is need for more studies to explore the nature of ecosystem services of the palace gardens and ecosystem services derivable from the royal bats, as well as potential conflicts between the bats and humans in their foraging spaces.

The Secret Life of Bees: Using Big Data and Citizen Science to Unravel…What Bees Are Saying about the Environment

Many voices. Greener cities. Better cities.

Once you start talking about bees, you open Pandora’s box…You’ll find small and very delicate stories behind them. Each one is interesting.
— Josep Perelló, associate professor and project leader of OpenSystems UB at the Universitat de Barcelona

If Josep Perelló is right about discovering the stories behind bees, Barcelona’s high-tech, citizen science-based urban bee project could soon have many interesting threads to follow.

By bringing together honeybees, technology and big data analysis, Perelló, an associate professor in the Department of Fundamental Physics and project leader of OpenSystems UB at the Universitat de Barcelona, and his multi-disciplinary team hope to uncover bees’ complex and often mysterious behavior.

“Beehives are the perfect example of a complex system. There is a whole society where some bees are doing some things and other bees are doing other things. They have a queen, and there is a sort of system of communication they use, too. They communicate with a movement or a sound,” says Perelló, who specializes in complex systems studies and analyzing large amounts of data streaming in from many sources.

That honeybees arrange themselves in complex organizations has fascinated scientists for ages, but the increased awareness about their environmental importance has recently made them good candidates for an open lab experiment.

“Bees can act as a biosensor for cities, and give a signal that could be easy to understand,” Perelló says. “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 the 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.

A new approach to beekeeping

To get the kind of data that would tell a more complete story about Barcelona’s bees and their surroundings, Perelló began looking beyond traditional research methods. Typically, bee behavior is monitored by sight and notes taken by scientists in a controlled lab setting. While that’s helpful in many respects, it doesn’t fully correspond with real-life situations.

Barcelona’s OpenBeeResearch project , which is overseen by OpenSystems UB and spearheaded by Perelló, bucks that trend. It makes a city park a living lab, and a colony of honeybees at the Museu de Ciències Naturals (Museum of Natural Sciences),  a building better known as the “Three Dragons Castle,” a beating heart of sensor-captured real-time data.

The project idea bubbled up in 2010, around the same time that citizen science initiatives were beginning to emerge globally and the value of public participation in science was being more widely recognized, according to Perelló.  And as the concept took hold, the project united people across many disciplines, attracting biologists, data scientists, physicists, engineers, beekeepers, technology buffs, urban gardeners, cultural managers, and artists.

Artist-duo Mar Canet and Varvara Guljajeva were among the project’s first participants. In 2012, they completed the Budgie Waltz art installation, where bird activity was converted to sounds. Every time a bird entered or left its birdhouse, light sensors registered the activity, which triggered a corresponding solenoid to push a piano key.

There seemed to be a natural segue into doing something similar with bees. Two questions needed to be answered: How could a similar setup be recreated to understand when the bees were leaving and returning to the hive, and how could the OpenBeeResearch group track which gates or access points the bees most frequently used?

“It’s a very collaborative project and hard to say where the origin of the ideas come from. But, we had this experience with the birds and experience with sensor technology, so it was quite interesting to see how we can do this for the bees,” says Guljajeva, who has a bachelor’s degree in IT, a master’s degree in digital media, and is pursuing a Ph.D in art and design with an eye for how real-life activities can be embedded into works of art. “It offers us a different perspective as well. In the case of the birds, we did the installment for the sake of art. But now, for the bees, we’ll have the scientific data that we can use and help make sense of.”

That data, in addition to helping scientists,  can also be visualized in a way that helps people understand bees and their communities—and, more broadly, human society, Canet says.

“We would like to produce a piece of art using the data from the bees. We don’t have a concrete idea of what that will be yet, but we think we will have very rich content,” says Canet, whose areas of studies and work spans from computer game development and data visualization to new media art installations. “We normally work with data. We like to sculpture [sic] data, and sometimes we use real-time feed data. The bees are a colony, and in a way, they are like our society. They are individuals living in a society. It will be interesting to see what the data shows.”

To develop a conversation about the project’s next-steps, OpenBeeResearch held workshops in 2012 and 2014 to figure out which variables to track, how to design the prototype beehive, what types of sensors and communications equipment could be used without harming the bees, and what lessons from other urban bee projects in Helsinki and Bordeaux could be applied to the Barcelona initiative.

Out of those discussions came the high-tech beehive prototype—a wooden box hooked up with infrared motion detection sensors, temperature and humidity sensors, and pressure sensors for tracking weight. The apparatus runs on free GitHub software and Arduino components for sound, weight and temperature (and eventually bee-counting); the data representation will be done with Data Science software. It was installed in June 2014.

In recent months, the team has been tweaking the sensors’ calibration, finishing final repairs on the prototype hive, and waiting for warmer spring weather. In the spring, the bees’ activity will increase and, in turn, there will be greater amounts of data that could provide snapshots of what’s going on inside and around the beehive at any given moment.

And, though it’s still a fledging project in practice, the OpenBeeResearch project has already had some early successes. It has received funding from Socientize, the Barcelona City Council, and the Fundación Española para la Ciencia y la Tecnología (the Spanish Foundation for Science and Technology) through the project Citizen Science Office of the Barcelona Lab. Recently, it was named one of 10 case studies lauded by the newly inaugurated Big Data Center of Excellence of Barcelona.

Surmounting obstacles

Although the project has generated interest across disciplines, has fostered public participation, and has sparked creative collaboration between people who may not otherwise have been connected, it hasn’t been without its challenges.

One of the initial snags was getting permission from the local city government to set up the hive. Unlike other cities in Europe and the United States, urban beekeeping is not allowed in Barcelona.

The workaround was to team up with the city’s Natural Sciences Museum and create a new bee colony from the existing ones there. The museum, located in Ciutadella Park not far from the city’s center, has a long history with rooftop beehives. It houses one of Europe’s oldest apiaries dating back to 1945, according to museum director Anna Omedes Regàs. Though it was not common at the time to see beehives on rooftops, the museum saw it as an opportunity to help train local beekeepers, be a resource for students and researchers, and provide tours to residents who were interested in bee science, she said.

For Jaume Clotet, the site’s beekeeper and a key member of the OpenBeeResearch project, the technology-based research initiative puts a new twist to an old idea. The OpenBeeResearch project puts a new twist to an old idea. “For us, urban beekeeping is not limited to installing one, two, or 20 beehives in a city with the idea to help [only with] their protection and conservation. Urban beekeeping can be applied and used in several areas of a city, including educational, technological, investigatory, cultural, social and, obviously, environmental fields,” says Clotet, who manages about 90 beehives in Barcelona province and in other areas in Catalonia. “Anything that is helpful to investigate and learn from the bees is interesting, and this is a clear example of how urban beekeeping can also be linked to the scientific and technology sectors.”

Another issue the team will be monitoring closely is if and how the technology itself affects the bees.  While bees are sensitive to electromagnetic fields, so far the chosen sensors and cable feeds don’t appear to be causing any interference or behavioral changes, Clotet says.

“From my point of view, sensors that can be installed in a beehive have very little effect on the bees’ behavior as they are sensors that only record data,” he adds. “It’s still too early to confirm, but we have not noticed anything that makes us think that the sensors affect bees. I believe that they could be affected by other waves or electromagnetic fields from the city rather than sensors in their beehives.”

What lies further afield for the project? We’ll have to wait and see what stories the bees reveal.

The Sensori-Motor City

Many voices. Greener cities. Better cities.

How can we measure the ways in which we perceive, are affected by, act and reflect on the nature of the city? The human body is a sensor-motor apparatus within a mutually moving nature-culture continuum. This sensori-motor apparatus has a vast capability of quickly evaluating vast amounts of information and acting on it while new technologies continue to extend human perception.

Remote sensing from satellites, airplanes and drones has replaced the cadastral survey from the ground, extending the body’s earth bound senses with continuous data from above. GIS has become the dominant mode of accurate measurement of spatial data, but cinematic, video and now smart phone eye-level camera views are almost universally employed to describe the qualitative feeling of a particular place at a specific point in time. Camera toting vehicles from Google roam the earth with the promise of integrating the map and street view into one tool. Satellites are now connected to the global positioning of our smart phones, combining both portable maps and cameras, and putting data gathering, mapping, filming and viewing in the hands of millions of people.

Crowd sourcing this data has a great potential to inform us about how humans behave within earth’s nature-culture continuum, if only we had ways of filtering and understanding this avalanche of information.

New tools are needed in order to understand the interconnectedness of nature and culture, where neither is fixed in space or time. Specific disciplinary tools such as those developed separately in the fields of cognitive science, architecture, film and ecology can be combined in order to find common knowledge among different ways of thinking and practicing and to connect quantitative and qualitative research.

This post introduces the concept of the sensori-motor city as a methodology to call attention to human perception, affection, action and reflection as discrete sets of information within the informational overload of the nature-culture continuum. Rushing by at twenty-four frames per second, a single film frame is an instantaneous slice of perception within the illusion of cinematic continuity. Frozen as an immobile cut, a film frame can be mined for information and measured as an instance of space/time.

The workshops presented here are examples of design-based research combining architecture and film techniques situated between cognitive and ecological science. While both sciences seek to measure complex systems, architecture and film exists in the space between perceiving, sensing beings and a world of constant flux. Human attention when directed towards understanding our selves as decisive agents within an environment in flux can lead to engaged sustainable design practices.

This blog post describes sensori-motor exercises that have made us more aware of how we perceive and act in the world, how we make choices and how we behave. The ability to measure the human sensori-motor system will inform more effective design strageties to connect rather than separate culture from nature.

Film frames as data on moments of the nature-culture continuum

The book Cinemetrics introduces the camera as a tool through which framed sets of information can be measured as immobile cuts through the continuous movement of matter in flux. Exercises from the book utilize film theory in order to understand human cognition and behavior in relation to architectural space and environmental stimulus. The workings of the human sensori-motor system can be understood through a frame-by-frame mapping of film sequences in order to draw attention to how we perceive the world through our senses, how our body is affected by those perceptions, how we act on those feelings, sometimes on impulse, and how we reflect on the consequence of those actions. By stopping the world through framed infomatic sets, we are able to relate perceptions and feelings to actions and learn to recognize impulsive behavior over time. Framed information from the ground can be aggregated to produce clouds of data informing socio-ecological science.

The architecture of cities extends the human sensori-motor system. Cities provide comfort, nourishment and pleasure. We need to tools to continue to adapt cities for that purpose while also measuring the environmental impacts of human behavior—the ecology of the city. The sensori-motor city is an idea of directing the human sensori-motor system towards sharper attentiveness and reflective action through careful analysis of film frames as sets of information, or individual pieces of data. The sensori-motor city is introduced here through a series of videos recorded during three undergraduate student workshops over the past year at National Cheng Kung University in Tainan, Taiwan, Parsons The New School for Design in New York and Chu Hai College of Higher Education in Hong Kong. Concepts and examples from Cinemetrics were put into practice through performance, video and drawing exercises.

All the workshops employ three brief film sequences to measure, frame-by-frame, how the human sensori-motor apparatus continually reframes perceptions, affections, impulses, actions, reflections and relations as immobile instances through the fluidity of the nature-culture continuum of urban life. First, students in the design studios of National Cheng Kung University in Tainan, Taiwan reenacted scenes from three movies, each with a unique filming method. Second, the students performed these scenes in the limited confines of a 3 x 6 meter space in the Taipei. Here the cultural differences between the three film directors became understood by comparative measurement. Thirdly, the film scene reenactments were performed in slow motion in the Aronson 5th Avenue storefront Gallery at Parsons The New School for Design in New York as part of a hand-drawing workshop. Machines were constructed to allow the hand drawing style to follow the method of filming of each film director. Finally, these drawing machines were recreated in order to record and measure ordinary human movement on site in Tsuen Wan New Town, Hong Kong. Based on this research, we call for new tools to understand cities as social and physical extensions of the sensori-motor system as the first step in making cities more sensitive and systemic and therefore more humane and sustainable.

The workshops are centered around three short film sequences from domestic scenes taking place in Tokyo (Yasujiro Ozu’s Early Spring 1956), Rome (Jean-Luc Godard’s Contempt 1963) and Los Angeles (John Cassavetes Faces 1968). Domestic scenes are ways of seeing cities from the inside out. All films take the viewer from the interior of the house to the larger natural-cultural changes that the microcosm of domestic life serves to represent. Since the students who participated in the Taiwan workshop were born nearly three decades after the making of these three films, their performance of the three film sequences offered them cross-cultural and historical insight into the emergence of the mediated consumer culture that came to dominate the world of global modernization they were born into. The lesson we all learned through the workshop was not just how to use film techniques to measure urban spatial experience, but also how the human sensori-motor system is transmitted and affected by media. Performing the roles of a husband and wife in Tokyo, Rome and Los Angeles generated lessons in empathy, for both the student-actors, audience participants and the general audience, as well as in measuring the social production on space in different cultural contexts.

Ozu’s films set during Japan’s post-war economic boom were made as entertaining melodramas appealing to the tastes of women living through an exceptional shift in domestic life during the 1950’s. The drama of Early Spring follows a young wife’s struggle to maintain the rituals of a traditional household while her husband, a new breed of white-collar salary man, succumbs to the boredom of modern commuting life. While Masako, the wife, dutifully performs traditional mourning rites for their deceased child, Shoji, the husband enters into a brief affair with an office co-worker. The film continuously “commutes” between the couple’s home and the husband’s office, and the in-between third spaces that constitute the rich social life of the city. Watching Early Spring, like many of Ozu’s films, we witness the huge social mutation of modernity from a small-scale domestic point of view, where the wife’s traditional sense of duty and devotion prevails in the end.

Godard’s Rome of 1963 is similarly caught in the post-war dynamics of an economic boom, but from a European socio-political perspective. The three-scene movie begins and ends on film sets of a Hollywood spectacle, and in between is the domestic scene where the married couple bathes and dresses to go out to watch a movie. The opening scene takes place in Cinecitta, the film studios built by Mussolini. In the film a Hollywood production of the classical Greek tragedy of Odyssey is dictated over by the fascist-like American film producer. The last scene of the film is a staged film shoot that takes place on the roof of Casa Malaparte overlooking the Mediterranean Sea. The pivotal domestic scene at the heart of the movie is filmed in a modern new condominium outside Rome. The apartment is the dream home of the married couple, the writer, and the former secretary, paid for by the writer selling is talents to rewrite the Greek tragedy for a Hollywood audience. Fritz Lang has a cameo role as the hapless European film director dominated by the commercial interests of the American producer. The couple’s struggles mirror Fritz Lang’s in that their dreams are now dictated by a new American hegemony, which came to dominate Europe following World War II. Contempt, Godard’s only Hollywood financed movie, expresses the director’s own dilemma in creating a work of art when film is in fact had become an industrial product. Godard’s critique of the new dominance of American consumer culture is situated dramatically here in Rome as the cross Atlantic natural-cultural continuum replaced the classical Mediterranean world.

Mapping of the panning camera in middle sequence of Jean-Luc Godard’s Contempt: coming home, bathing, getting change and going out. While Ozu’s camera shifts around the perimeter of the scene in three stationary positions, Godard’s camera is located in the center of the apartment and continuously pans as the actors move around from room to room. The diagram repeats the same grey tone depicting in plan what is captured within the film frame, but also adds a time line where each line indicates one second around the arcs generated by the panning camera.

Cassavetes takes us to the capital of this new empire of the Hollywood spectacle: Los Angeles, 1968, a most auspicious year for societal breakdown. Here we are in the decadent heart of the mid-20th century American consumerism, as the husband Richard is a prosperous movie producer as well, with a car, a beautiful wife, Maria, and a large home in the hills above Hollywood. Richard, like Greek-American Cassavetes, is living the “American Dream.” Cassavetes, however, remained outside the Hollywood studio system, as his films were deemed too experimental. He financed his films independently through his own acting career in Hollywood films, and relied on his wife, family and friends to act in is movies. Faces was shot in his own home he shared with his wife and star of many of his films, Gena Rowlands, who plays Richard’s mistress Jeannie in Faces. For Cassavetes and his ensemble of actors, the American dream was portrayed in fact as a nightmare of unrestrained and uninhibited impulse.

Cassavetes camera is hand held, so this diagram measures the distance between the camera and the head of the actor. Both are continuously moving at high speed throughout the scene as actor and camera run into the house, up the stair and out the second floor window.

Performing these three sequences helped us to understand how the cities in which these films are located could be understood through measuring and comparing the embodied habitation of each. Additionally, while each of the three directors filmed a husband and wife in domestic routines, the film style shifts radically—from stationary and meditative to slowly moving and geometric to impulsive and dynamic. With industrialization and modernization, cities are often blamed for both human and environmental “breakdowns.” These workshops help students understand how sensori-motor breakdowns are, in fact, part of a feedback loop between human perceptions, feelings and actions in culturally constructed urban environments. The exercises provide the source for new ways of thinking and living within the mutual movement of nature and culture. Performing the three film scenes generated embodied empathetic knowledge of the breaking points and blind spots of consumer culture. This embodied knowledge came from inhabiting media as well as the globalized space of an international workshop and expositions.

Additionally each film director has a distinct way of framing the nature-culture continuum. Ozu patiently portrayed the social mutation of post-war Tokyo by framing separate shots that illustrate the basic movements of sensori-motor system: perception, action and affection images respectively as long, medium and close-up shots. Godard scans European culture under assault in the banality of American style consumer culture with a slowly moving yet monumentally framed cinemascope camera. Cassavetes exhausts these movements and assembles a montage of bodies experiencing physical and psychological breakdowns with his innovation of the hand-held camera.

Ozu, Godard and Cassavetes not only provide clear examples of the human sensori-motor system, but they are exemplary of the new direction in film following World War II that is inhabited by bodies that do not know how to sense, feel or act [see Note 1 at the end of this essay]. Cassavetes and Godard’s films end as Ozu’s starts – as pure optical and sound image beyond the endless cycle of perception, affections and action. After a sensori-motor breakdown, inventing the new ways of perceiving, feeling and acting within the nature-culture continuum becomes possible.

Measuring the Sensori-motor City

The first workshop in Taiwan involved the students rehearsing the three film scenes in order to perform in a 3 x 6 meter space in the Tapei World Design Expo. The directive of the workshop was to match as closely as possible the original film within the spatial limits of the Taipei World Design Expo venue, and to consider how to attract an audience to the performance. Yasujiro Ozu filmed Early Spring in a sound stage in Tokyo. The set for the domestic scene depicts a modest working class home with sliding shoji screens, tatami mats, and several neighbors’ homes located directly across a narrow alley. The scenes’ separate shots are staged as composed tableau-like theater sets, precisely filmed at right angles.

The setting of the Early Spring’s opening scene easily fit within the 3 x 6 meter Expo booth space. The challenged faced by the Ozu student team [Note 2] in performing this three minute sequence was not one of spatial limitation as the film is a vivid depiction of the frugal and efficient use of space in Japanese tradition. Rather, the challenge was in representing the multiple angled cuts within the three-minute sequence to the audience. Should the live audience remain stable like in the theater, or be encouraged to walk around the performance in order to understand the shifting camera position? Both the 90-degree camera rotation, and altering distance from the performance were critical to Ozu’s film making technique.

Rehearsal of the opening sequence of Ozu’s Early Spring:

The Ozu team constructed a portable set which conveyed the bedroom scene, while at the same time revealing the shifting vantage points from which the scene was shot by constructing framed openings. Students took on various roles, actors, timekeeper, scenery, stage blocking, and director. The audience was not only encouraged to walk around the set in order to understand the multiple camera positions employed by Ozu, but also were given scripts to perform a role in the scene itself. Ozu’s method of matching is cuts precisely within an actors movement, for instance the wife and husband getting up in bed, is performed in stop-motion by the student and audience actors, in order to shift the camera viewing position with the actor’s body motion.

While Ozu shot his film in a sound studio—his framed “set of information” is literally a constructed set—Godard carefully selects and arranges the settings for his films from scouted locations. The modern apartment at the heart of the film is an “art directed” set, carefully arranged to mimic the incompleteness and barrenness of the couple’s marriage. Godard’s filming style of the domestic sequence is a remarkable example of long, uncut sequences. The panning camera frames a variation in subject distance similar to Ozu’s long-shot perception image, medium shot action image and close-up affections, but in Contempt the images are continually unfolding in time rather than separated by discrete edited cuts. The camera slowly pans, while the actors are moving about often in opposite directions creating a complex choreography of image variation.

Rehearsal of sequence from Godard’s Contempt where the students measure the movement of actors, camera and props by tracing their footprints:

The task of the Godard student team [Note 3] both revealed the difficulty of matching the syncopated movements of the actors and the camera, but also the dimensional fact that the spacious Roman flat that Godard chose for the pivotal domestic scene of the movie extends far beyond the 3 x 6 meter exhibition booth at the Taipei World Design Expo. The student team therefore developed a system of moving the background scenery, along with the performing actors, in order to give the illusion of an elongated set as viewed by the centrally placed panning camera. The team also developed a method of recording the changing positions of the actors, set assistants and cinematographer, by dipping hand made sandals in color-coded paint during rehearsal, producing a footprint map of the performance. In the final performance the team coated the black floor of the Design Expo booth with white flour, leaving traces during the performance like footsteps in snow.

Godard performance as part of an exhibit at the Taipei World Design Forum:

Cassavetes filmed the domestic scenes of Faces in his own home in Los Angeles. Filled among the ordinary mess of domestic paraphernalia rather than a sound stage or an art-directed set, the film takes on another level of immediacy and reality. The scale of Cassavetes’ large two-story home presented a considerable challenge for the NCKU team [Note 4] Their task was to present the final scene of the movie where the husband runs up stairs and chases his rival outside and over the garage roof within the same 3 x 6 meter space in the Taipei Expo. The action quickly travels through the two-story extent of the house captured by Cassavetes’ hand-held camera. By focusing on the information within the constantly moving camera frame rather than the spatial extent of the house depicted, the student team was able to create the illusion of a two-story house chase scene within the 3 x 6 meter Design Expo booth. After numerous trials and errors in rehearsal, the team concocted a way of suspending an actor performing the role of the husband horizontally across a moving backdrop of a painted stairway. By turning the plan view of the camera to an elevation, the team created the illusion of the shot in which Cassavetes film Richard running up the staircase from above, thereby compressing a large two-story American home into a small exhibition booth.

Rehearsal of sequence from the final scene of Cassavetes’ Faces:

New York Drawing Workshop: Slow Motion

The Drawing Lab, led by Jose DeJesus at Parsons The New School for Design, transformed the School’s Aronson Gallery into a three-dimensional data mining and drawing apparatus. The installation accumulates works made by the public: free-hand drawing, photo and video, spatial diagramming and measurement, textual performance and language play—all cinemetric tools of the Drawing Lab.

The Taiwan performances were repeated in slow motion in order to allow for simultaneous drawing of the movement of the actors. Jose DeJesus designed and constructed “drawing machines” that matched the camera technique of each director. Each film sequence was mapped and measured on the gallery floor with colored tape: black for Ozu (still camera in seated position), red for Godard (panning camera in standing eye-level position), and yellow for Cassavetes (hand-held camera). The students could measure not only different ways of “acting” in the world, but also different was of framing the mutual movement of nature-culture.

Measuring the Cassavetes performance with tape on the gallery floor:

Finally, in March 2013, at Chu Hai College of Higher Education in Hong Kong, students and faculty from Chu Hai, Parsons, NCKU, and Chulalongkorn University in Bangkok, Thailand participated in a workshop [Note 5]. The workshop topic was how to recycle the older “New Towns” in Hong Kong, now that factories have been relocated to China, commercial spaces have been left vacant as shopper prefer the malls in central Hong Kong, and the majority of residents are aging in place. Furthermore, the question of the nature-culture continuum is particularly extreme in Hong Kong, as the city has been planned to reserve 65% of the territory as protected natural areas, while most of the city consists of high-rise residential enclaves built on top of podiums. Here students filmed the everyday movements of the New Town residents, and then placed the cinemetric drawing machines in situ in and performed the movements they recorded.

Godard drawing machine in Tsuen Wan New Town, Hong Kong:

This latest step in our collaborative research brought us closer to our aspiration of utilizing sensori-motor tools for participatory urban ecosystem design: first, by making clear how we perceive, are affected by and act in the world, and then how to reflect and relate our actions towards natural-cultural transformations. Measuring the sensori-motor system brings attention to sight, hearing and kinesthetics in relation to environmental change.

Further explorations include smell, taste and touch—all absent when graphically analyzing film frames, but present to participants performing in the workshops. In our last exercise in Hong Kong, by brining the drawing machines into an urban space, we created new ways of sensing and acting within the nature-culture continuum. Fundamentally, Cinemetrics instills the knowledge that we change the environment by first changing our perceptions, our actions and ourselves through reflective feedback and relational behavior.

The Seven Habits of Highly Effective People Who Want to Do Ecological Restoration

Many voices. Greener cities. Better cities.
Stay humble. Be timely. Celebrate elements. Invite knowledge. Welcome friends. Communicate. Stick to it.

The Nature of Cities website has advanced the understanding of cities as both harbors for biodiversity and as places where there are many opportunities for natural habitats and ecoservices. Steadily, ecological scientists and practitioners are restoring habitats within the world’s cities. Ecological restoration is not just for the “wild” lands where people go for their holidays; it is for where we live and work. What are the steps needed to succeed in advancing our cities’ natural capital? This editorial suggests some behaviors of urban ecologists that may advance our common agenda.


We’re surrounded by do-gooders who write, lecture, post, and generally harangue us on how to be better people, partners, patricians, and personal fitness champs. The New York Times even publishes a weekly bestsellers list of advice books. But what about us?  What nuggets can move us from being merely waterers of native plant seedlings to a movement that is playing its role in saving the world?  What habits must be ingrained to keep us moving towards this oft-cited goal?

Habit 1. Admit ignorance.

Drop the conceit that you know everything about your site’s physical and biological conditions, its varying hydrologic state, the long-term changes in community structure, and past land uses which intrude on reasonable goals for your project. Expect many of the plants you installed to die. This is an expected outcome, not a failure. Almost no project has enough time to do background analysis to predict the stresses and constraints that will impinge on your habitat restoration plan. Be humble. Ignorance of every one of the site’s needs frees us to experiment with many plant palettes, many small-scale ground plane interventions, and a chance to record the stochastic nature of the developing living world. Enjoy watching it unfold.

Habit 2. Dont confuse the past with the future.

The world is changing. It always has changed. Detailed knowledge of the literature describing the site’s biota 100 years ago or 50 years ago, may be irrelevant in today’s climate, landscape ecology, human interferences, and changing biodiversity. And after today’s conditions, tomorrow’s may be even more peculiar. We cannot predict the future so do not assume it will be like the past. It will not be like the past. We consider this another reason to nurture the humility which must grow within you.

Habit 3. Celebrate Earth, Wind, and Fire.

Nature is not static. Disturbance regimes vary in frequency, intensity, and duration. The past metrics for disturbances will change in the future (see Habit 2). Episodic events have an enormous impact, which can persist for decades. Yes, I know you’ve lived in your town for five years and know it well. Assume that the critical events happen every six years, and you really don’t know at all what they will be. Do not lose your sense of wonder over the impact of landslides, windstorms, and wildfires. Things may have been quiet in your community the last few years, but nature can tell you a direct lie when she wants to.

Habit 4. Welcome knowledge. Nerds rule.

Our communities are full of people who traffic in rumor and superstition. They give us advice all the time. Nature will come back, some say, as if all the plants missing for the past few decades will magically disperse in, grow, and harbor all those animals that also have been missing for those past few decades. Others will say that those invasive species that are rapidly diminishing our biodiversity aren’t so bad after all. They are just different from the past; that’s not so bad. Happily, there’s a large group of hard-working people who do manipulative experiments and careful statistical analyses. Their writings can be dense and sometimes hard to follow, but they are peeling back the layers of ignorance towards a real understanding of how living plant and animal communities work. If our field is not fact-based, it becomes a three-dimensional fairytale, but there is no living happily ever after. Study restoration science.

Habit 5. It takes a village. Build one.

Our passion for the natural world and trying to improve it is very personal, as true love always is. Restoration cannot succeed by leadership by lone wolves. Like those wolves, the practice of restoration ecology requires a pack of workers. We need people with complementary skills, teammates. They keep our energy and enthusiasm high. We need people to do follow up maintenance, monitoring, and pushing our local governments to nurture our projects after we have left the stage.

Habit 6. Go tell it on a mountain.

People forget. We need outreach to remind people why the project was done, why the project is valuable to us, and why care of the project is just as important as other community maintenance needs. Explaining ecological services and the dynamics of restored communities to neighbors and to governments at all levels is a continuous process. We live in an age when the variety of media outlets is enormous. Some or all of them are needed to keep telling people why the restoration was done in the first place. You should not forget that other people forget. This is not an insult, but the reality of human nature.

Habit 7. This is a longterm relationship.

Too many projects fail after several years as the original champions move on, or are promoted, or are forgotten by too busy administrators who themselves have moved on to the next great idea. We need continuity of effort. Build a long chain of enthusiasts for your project. Someone has to keep the torch burning far into the future. If you have not made plans for long-term care, maybe you shouldn’t even have started the project. If you can’t keep your torch burning you may very well be making an ash of yourself.

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

Many voices. Greener cities. Better cities.

“Absences should not cause us to look elsewhere, but to look closer.” i

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.
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.ii 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.

Like any research project, this began with a question. I was struck by how conversations about the ocean describe the ocean in terms of the material in it. The salt, the warmth, the life, the boundaries. I thought about the tremendous verticality of the water cycle and wondered if there was a way to share the awe of that zone without resorting to giant squid, rims and trenches, or garbage patches. The ocean is mostly de/void space, so we are unable to gain any focus on it—like looking into a bowl of water. Can we talk about the emptiness—which is surely integral to the fullness by virtue of the fact that it exists? Can we talk about the emptiness in its own terms?iii At this stage of mapping, three quadrants are revealing themselves: air, ocean, and emotion.

I’m drawing this map in my home office, which has a window and a small balcony that looks from one story up onto a three-lane road. I can see an autoshop, a gym, a dive bar, and a pizza place as well. It is not highly trafficked, but it is a route for big rigs, and has a few bus lines that stop at the metro station, where I can see commuters move in and out of the building’s bright, brutalist entrance.

This is to give you an idea of how what I can see from my office is a good indicator of human behaviour. The view doesn’t change much when the weather is nice (like it would if the street were lined with terraces), or on a first Friday (like a street lined with galleries). What I overlook is the movement of the every-day. These days, I bear witness to the quarantine with a view that overlooks the emptying of a nondescript corridor.

Empty can speak to a present nothing, but mostly it means that something that ought to be there is not there. Empty does not mean unexplored. If something ought to be somewhere, if somewhere ought to have something in it, then we, humans, have always found a way to fill it: dark matter, sea monsters, commodities.

When you try to focus on the water and not the bowl, you realize it’s not empty—emptiness is not a state, it’s a metaphor. The state that emptiness is often trying to describe is merely homogeneity. What it is, is substrate without any noticeable change within it. A substrate that can accommodate something other than itself, be divided, be combined, be contained—even, in some cases, be released.

The air is a substrate. If I try to look at the air between my office and the metro station without looking at the things that are not air, it is hard to see.

Funny thing, though: wouldn’t you agree that wind is not air? In motion, air becomes a force of nature, its effects perceptible in myriad ways, while still air somehow ceases to exist.

In the quiet of a deserted urban corridor, bird song, insect buzz, the scent of lilacs, catalpa, and a distant radio rush in to fill the air like a vacuum-sealed container popped open. And now, on this street, even air is not air because lingering in the space between my body and yours is our respiration, our habits, our households, and, perhaps most densely, a microscopic, sun-shaped enemy. Suddenly we can bring the emptiness between us into focus.

I wanted to think about the emptiness of the ocean because emptiness is political. Colonialism requires a perception of emptiness in order to occur. To consider the Atlantic Ocean empty is to actively deny that it is also a graveyard for enslaved people—a place of mourning and culturicide.iv Twentieth-century British marketing understated the vastness of the spaces between their colonies and thus implied dominion over them,v and Victorian cartographers depopulated South Eastern Africa all together in order to prove its readiness for European settlement.vi The scene from my office window is a direct descendent of the earliest alterations committed on the land by French colonists who did not see that Turtle Island was replete with people and landscape because their eyes could gain no focus on that which was not domesticated in their terms.vii The systems that care for certain human lives more than others do so because they can’t fix their vision on the life contained in the body—these eyes have learned to see some bodies as empty, not necessarily articulated as void space, but in the othering language of exoticism and wilderness.

If I can find a way to describe the homogeneous substrate of the open ocean without recourse to life, boundaries, or change, then I may be able to address the lack of care that so profoundly affects it by giving it its own form on which to focus. Language comes into play here, if metaphor is allowed into the discourse: not, “There’s nothing here,” but rather, “This place is filled with material that is unconcerned with how it will accommodate our bodies.”

Emanuele Coccia speaks about immersion in his 2017 Life of Plants (tr. 2019), saying: “Plants…allow us to understand that immersion is not a simple spatial determination…[it] is an action of copenetration between subject and environment, body and space, life and medium…otherwise one would speak simply of juxtaposition or contiguity between two bodies touching at their extremities”.viii Human bodies, he says, feel this most acutely when they swim, as water acts upon them and they act upon the water in equal, indistinguishable, measure. I think of the work of Agnes Martin, who, according to Olivia Laing, hoped that her monotonous, haunting paintings would “have an emotional impact on you that was like walking up to the ocean, that flooded you with a kind of feeling of happiness,” ix as well John Cage’s 4’33”, which, in its silence, reifies all sound to the status of music.x Works like these have the effect of inverting the primacy of the world and the atmosphere; the universe of things and the universe-as-thing.

This is all to say that there is no such thing as emptiness, only substrate, and that there is no such thing as empty, only more and less full of that which we acknowledge and value. In quarantine, we can feel the fullness of our environment pressing on us with force. It is filled with anger and anxiety, gratitude and hope. It is less filled with friends and family, museums and movie theatres.

I’m looking at my map of emptiness, and about what compelled me to take this tangent from the open ocean—arguably the least urban place on the planet—to my asphalt landscape. This week, the air was filled with willow pollen, reminding me of marine snow or microplastics caught up in currents. They make wind visible to me and remind me that the air is teeming even if I can’t see it. To me, this responds to Bruno Latour’s call for reflection on what habits we may wish to reconstruct or to interrupt completely.xi In our eagerness to rush back to the exterior, the status quo will latch on to us when the seal of quarantine is broken, as though the street were an empty stage, waiting docilely for players to return and perform the every-day upon it. To prevent this, we may use our apparati of perception to fill the space—to understand that it is not a vacuum.

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. In the same way that finding focus in the deep open ocean may give us the motivation to attend to it, now that we can see the air in between my face and yours, we may insist on sharing that space with a revived sense of the need for a radical redistribution of resources and care.

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

Many voices. Greener cities. Better cities.

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.
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 situation have brought the northern English city into the national headlines, drawing scathing criticism from the environment secretarya former Council leadermusic celebrities, and political analysts, not to mention landscape professionalsurban ecologists, the University of Sheffield, and the Woodland Trust.

The Sheffield “tree massacre” is the result of a private finance initiative (PFI), a form of public-private partnership that should theoretically improve efficiency on public spending. When Sheffield City Council signed a 25-year PFI contract with a multi-national infrastructure support service provider to upgrade the city’s streets, the effect on the city’s leafy avenues could not have been anticipated.

There were some clues, however.

Most notably, the contract was negotiated behind closed doors, without any discussion in Council Chambers. The only version released for public examination was a heavily redacted document, with sections blacked out on account of “commercial confidentiality”. Effectively, taxpayers are required to pay for work about which they are legally not allowed to know. The situation was confusing from the start and has escalated into six years of conflict, in some cases posing grave questions about the democratic state.

A flawed contract

Signed in 2012, the brief of the £2.2 billion Streets Ahead PFI with Amey Plc is to upgrade the city’s roads, pavements, streetlights, bridges, and other infrastructure. Although it is a highways contract (i.e., not a tree contract), thousands of mature street trees are being replaced with 8- to 10-year-old saplings. Trees are technically removed if they are one of six “Ds”: dangerous, dying, diseased, dead, damaging, or discriminatory. The two most frequently used of the 6Ds are “damaging”, in which the tree damages footpaths or curbs, and “discriminatory”, meaning trees that are perceived to create difficulty for elderly, disabled, and partially sighted.

The Council affirmed that felling is a “last resort”, and the contract includes a variety of common, low-cost methods for repairing pavements. One Councillor has stated that flexipave was ‘already used’ in 143 occasions’, but an investigation in 2016 by the Information Commissioner found that none of these alternatives had been used in the first five years of the contract, even though they are paid for.

When residents noticed that healthy and mature trees were slated for removal, people began to protest. Knowing it is a 25-year contract, campaigners feel that Amey is trying to avoid the costs of pruning and maintenance over the long term. Conflict flared in November 2016, when contractors arrived at Rustlings Road at 5 am to cut down trees that residents had demanded should remain. Three people were arrested, in their pyjamas, for standing beneath the trees they wished to defend. Two of of those arrested were retired school teachers. Since then, at least 20 people have been arrested under a Thatcher-era anti-union law.

The situation was in full swing at the time of this writing, with breaking news emerging the day of deadline, so this essay was basically an archive from the moment it was published. For current news, check out Sheffield Trees Action Group (STAG), the non-party-political umbrella group representing the local tree groups that emerged across the city. While there are juicy bits, such as the 100-year old listed memorial trees, the bizarre allegations of “tea gate” or the embarrassment of #tootgate and other arrests made over musical instruments, this essay focuses on the PFI and how it relates to urban and human ecology.

The PFI and the politics

An independent survey in 2006-2007 suggested that 1,000 trees needed replacing, and approximately 10,000 needed “some form of remedial treatment”. A second survey was conducted in 2012 by Acorn, the arboreal firm that would later be sub-contracted to carry out the replacement work. That survey (which has since been removed from the Council website) stated that the majority of street trees would require replacement after 70-80 years. In 2012, City Council reported the intention “to replace about 18,000 of 36,000 trees over a 25 year period” (7.4, point m). The possibility of a target for tree replacements was a mystery from the start, both to the public and to many members of City Council.

To address public discontent, in 2016 the Council conducted a household survey to determine the degree of support for the tree replacements on affected streets. Of the 13.4 percent response rate, 6.75 percent agreed, and 6.65 percent disagreed with the replacement program. It was odd, then, that a Councillor would state in 2017 that “the majority of people in the city want to see this work carried out”. As an outcome of the survey, an Independent Tree Panel was formed, comprising impartial experts that would liaise with stakeholders and with Council in situations where 50 percent or more households opposed the work. However, trees were removed before being referred to the Panel on at least three streets, and in some cases before residents had had their say. By Feb 2018, about 5,500 street trees had been removed. To make matters worse, a horticultural critique has noted that most of the saplings will die young and will not reach the maturity of the trees they’ve replaced.

On March 12, 2018, the politics of the situation became slightly clearer. Whereas the Council had consistently denied that there was a target for tree removal, it was finally ordered to reveal the redacted passages of the contract under the Freedom of Information Act. According to the document, “not less than 200 per year so that 17,500 highway trees are replaced by the end of the term”, meaning that about half of all Sheffield’s street trees would be replaced. Even with this new transparency, the Council cabinet member for the environment has responded by saying that “any suggestion that 17,500 trees is a target or a requirement is an incorrect interpretation.” If confusion is a strategy, then the prize goes to Sheffield City Council under the influence of this PFI.

Urban ecology

One of Sheffield’s oldest trees slated for the chop included the Chelsea Road Elm, a veteran tree between 100-120 years old. Not only is the Chelsea Elm a gem for its genetic resistance to Dutch elm disease, but it also harbours a colony of the White-letter Hairstreak, a priority butterfly species in the UK Biodiversity Action Plan. With these concerns, local residents apparently commissioned an engineer to provide an estimate for addressing the cracked paving and discovered it could be done without felling the tree, at minimal cost.

Nevertheless, the cabinet member for the environment is quoted saying: “Due to the deteriorating condition of the tree, we now have to carry out pressing safety work to tackle extensive decay in the tree to ensure public safety.”

When I visited the Chelsea Elm in early February 2018, the tree was decked out in masses of devotional content, including poetry, drawings, sing-alongs, and love letters alongside bunting and knitting. Examining its winter silhouette from all angles, crown die-back and dead branches were not evident, certainly not to the extent of “extensive decay”.

The roots of the Chelsea Elm have caused some uplift. Photos: Christine Thuring

With regards to the paving around the base of the tree, the roots have indeed caused some uplift (see above). Recalling the alternative solutions that are covered in the contract, and with respect to the stature and significance of the tree, this should be a textbook example calling for a tree pit or at the very least, permeable paving.

By extension, the situation as it stands raises the question about the materials used for sidewalk paving, maintenance in general, and also the logic for absolutely straight curb lines (with no deviation!).

Fortunately, the felling at Chelsea Road was prevented thanks to over forty dedicated supporters who stood vigilant by the tree for hours in the freezing cold. In mid-February, after a series of meetings between City Council, Amey, and Sheffield and Rotherham Wildlife Trusts, it was agreed that the tree would be pruned with sensitivity both to the butterfly colony (i.e., the eggs laid on the tree the previous summer) and for the tree (which could still be at risk of infection by Dutch Elm Disease, since resistance is not the same as immunity).

“Reasonable force” has been used against tree defenders. Photo: Sheffield Trees Action Group

A sensitive pruning was conducted that left enough growth for the butterflies to remain in situ. Were it not for the peaceful tree defenders, this tree and the butterfly would likely both have been destroyed.

New forms of urban (wild-)life: injunction and evolutionary radiation?

The legal pressures of the conflict mounted in August 2017, when the Council gained a High Court injunction against those “trespassing within safety barriers”. The injunction for trespassers includes contempt of court, imprisonment, fines, and/or having assets seized. In early 2018, security measures ramped up significantly, with “specially-trained stewards” contracted to remove trespassers with the authorisation of using “reasonable force”.

Witnesses have provided evidence of assault, even on elderly peaceful protestors, and a worrying lack of health and safety on all operations. The escalating police presence, and its questionable neutrality led to an expression of concern by a former council leader, noting that the removal of one tree in early March involved 33 officers and 20 security staff.

Despite substantial legal costs, the injunction has largely failed to deter protests and has led instead to creative responses by an increasingly committed community of campaigners and citizens. To continue defending trees in this criminalised environment, citizen responses have adapted depending on how much risk they are willing, and able, to take. These new strategies take their names from the animals they imitate.

So, for anyone wishing to dedicate themselves to preventing a tree from being cut down, they can choose from any of the following roles:

  • Gecko: clings to walls near threatened trees, but outside of the completed safety zone and therefore not in breach of the injunction.
  • Squirrel: climbs trees. To date, no one knows if being up a tree before a safety zone has been erected is in breach of the injunction; this has yet to be tested in court.
  • Bunny: hops over fences defining a safety zone. Once the safety zone is complete, this is in breach of the injunction, so a bunny may be guilty of contempt of court.
  • Gnome: sits in a garden (either their own or with the owner’s permission) under any hanging branches from a threatened tree. This is not in breach of the injunction.
  • There are also Owls that conduct night patrols, and there has recently been talk about Hedgehogs, though this manifestation has yet to fully emerge.

In closing

The situation in Sheffield is just one manifestation of how wrong public-private partnerships can go. An investigation of 36 strategic P3s in England that were signed between 2000 and 2007 found that more than a third of these (13) had “since gone back in-house”. In 36 percent of those cases, councils found that it was more economical to manage their own needs rather than outsourcing to commercial companies.

There are a few examples of council’s terminating these agreements ahead of contract end, as in LiverpoolPeterborough, and Cumbria County Council. The proof is in the pudding: local authorities can best serve their constituencies by investing in and managing public services in-house.

Out-sourcing is out-dated

It seems like Sheffield City Council has lost the plot, and taxpayer money has been mismanaged, but it’s not too late to fix this. The Environment Secretary recently offered that Westminster will do “anything required” to end the tree-felling, including helping to pay contract termination penalties. To save the city and its reputation, for a start the Council should end the PFI, refresh the priorities of the South Yorkshire police force, and enlist a collaborative, multidisciplinary team in defining what an Outdoor City looks and feels like.

Crucially, the Council must win back the trust of the public. The citizen tree protection movement has been consistently peaceful, united by coherent and informed wishes (for example), and this is an excellent opportunity to give democracy a chance. Council elections are coming up in May, so change is in the air, regardless of what Council decides to do.

Quiz or joke? How many security officers does it take to cut down a tree in Sheffield? Photo: Anne Goodenough

Lastly, the response by civic engagement seen in Sheffield is an inspiring and bright beacon of hope in the current landscape of corporate bullying. Ordinary people continue to respond and stand up for what they believe in, and this has created a dynamic, supportive and creative community guided by the spirit of place-making. Similar, the degree of organising and communication has led to an agile movement. While many trees have been removed, a great number have been protected.

In an interview on BBC Radio 4 (March 16, 2018), former Pulp frontman, Jarvis Cocker, said: “The seventh “D” is daft. It is very daft to get rid of so many trees”. Cocker and other musicians are supporting a fundraising campaign to offset the legal costs of tree defenders. It may be too early to say, but I have a hunch that this community spirit—whether crowdfunding or any of the myriad forms of grassroots social investment that have emerged through this fiasco—is an essential ingredient to loosen the small-text grip of destructive PFI/P3 contracts.

Power to the peaceful, and peace to the powerful.

On The Nature of Cities

The Singing Air

Many voices. Greener cities. Better cities.

“…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 weeks, my wife and I have taken to a winter ritual that few of our Berlin neighbours understand. We prepare for it when the sun is sending its oblique rays from beneath the clouds on the western evening sky, strikingly colourful in this season, when the air becomes colder but the colours warmer, often a mix of gold and light violet like on medieval altar paintings. When dusk starts to fall, we get on our bikes and head off to the Grunewald city forest which starts a five minutes ride away. 

The dance of the crows on that cool evening in the forest, was the dance of nameless ragged shapes—a Brownian movement of giant croaking molecules, mixed with some lesser cackling jackdaw atoms. The Brownian molecular movement revealing itself as the self-experience of the huge Psyche which this all is.
We are eager to leave the streets lined with barren sycamore trees behind us, to cross the railway and subway lines on the concrete overpass which holds the huge traffic artery. At this hour, cars and trucks are gushing out to the west, into the suburbs, leaving a shimmering wake of red taillights trailing behind, a sunset in its own right. People we know who meet us on our way to the forest usually ask us if we are really serious to go there when it becomes dark. We should be coming back home at that hour, not entering the “dark evil forest”, as one neighbour put it recently. “Are you serious that you want to go there?” 

Oh yes, we are.

Our hikes into the woods started by chance—or, better—due to my way of organizing, or rather not organizing my writing after lunch break and a short nap, trying to squeeze in as much work as possible until darkness falls. When it is time to go to have enough light, I often don’t move because I need to watch the sun setting between all these drifting colours, making each fleeting moment unique and ephemerous. Every time I seem to encounter an eternal principle which I still have not fully grasped. So, it is mostly near dark when we go.

Last time we went, like always I clicked off the dynamo for my bike’s headlamp at the fringe of the woods. Inside the forest the immediate change of atmosphere felt like a soft shock. Branches and twigs populated the dim air, which smelled of forest, of a different realm to the world outside. There are still some logs lying across the path after the last huge storm more than a year ago, and we had to make careful detours. No sound in the air, apart from the traffic noise which became dimmer with every turn of our wheels. 

Riding more deeply into the forest, we stopped talking and let our skin be greeted by that other skin, those innumerable encounters of air, moisture, wind, scent, molecules bumping on the mucous membranes inside our noses, and dim glow making our sight switch to peripheral vision. The leaves release their wet and cool scent that conveyed a gush of serenity to me. It seemed to touch a chord, a fiber of my body that is buried very deeply in my flesh, in my own particular way of being a chunk of earth. The forest was seemingly dead, barren, still. But I could sense that it lived under the winter torpor. I could smell that the soil was alive, and I sensed some other live faculty with a sense we cannot name yet – maybe the experience of being inside a huge whole which is not just a thing, but also a focused experience, a self, or a community of selves, just as I am.

As darkness fell more deeply during the minutes of our ride through the woods, our vision became stronger. The forest differentiated into fine grades of paler and darker gray, as though every bark, every twig, the cool soil emitted a weak light without any colours. All brightened up, where should have been deep darkness. Night in the forest was actually brighter than night on the well-lit city streets, where the lamps create that much more darkness where their shine doesn’t reach. If only our neighbours knew. 

Then we heard the first faint caw, somewhere in the pale air above. A call coming from nowhere, swirling over our heads, quickly ripped apart by gushes of cold air. There was another one, and yet another one, slightly different in tone, closing in, and then more calls were coming, drawing closer, cawing, croaking, interspersed with some distant cackle. The crows had started to pour in and circle the sky above our heads. 

We headed towards a small clearing which had become “ours” over the last years, had been our place of rest during long spring evenings, resonating with the chants of blackbird, song thrush, and nightingale. We had cared for a little oak during early spring and summer, coming nearly every evening to water it when rain had cut out for many months

The calls grew louder, coarser, ragged, rapped apart, raucous, intense, filling the sky with guttural voices. It was the song of winter, more raw, broken, and harsh than the multivoiced concert of summer. And still it was the same breathtaking experience of quivering life, of “the reservoirs of darkness stirred” (W. H. Auden, New Year Letter, London, Faber & Faber 1941). It was always the same life, and this same life was always spelt out by voices. We dropped our bikes to the ground. When we turned our heads up, the clearing opened like a window into the evening sky.

And there they were. The crows came in as pushed by a gust of wind sending black fragments across the air. The sky filled with voice, and with movement. Black bodies, stretched and bent, pointed wings flapping, whirling about, rolling over one another, sweeping around in sudden bends and brusk loops. The flock passed and curved, then disappeared over the pines and the barren maple trees, only to turn back from behind our backs, merging with another group in the air above. There where more voices, coming from different directions, smaller groups, singular individuals. It was a huge gathering, with crows coming in obviously from all over the south-western part of the city, dozens, hundreds, maybe thousands of voices and wings making the sky crack.

This was not a small flock occasionally choosing these parts of the forest as a roost for chilly nights, but a major, and ecologically important, agglomeration. A significant part of the crow population of the capital had chosen our summer clearing and the adjacent woods as resting place for the night. There were huge numbers of individuals, and at the same time more than numbers, more than many single individuals but one compact mass, a wall of sound, compacting with everything else in the pale light. The air became crow, rook, and jackdaw.

The flock aggregated, dissolved, merged again. The birds flew close curves all at once, their wings tearing apart the cool air with a hissing sound which made me feel the smooth and cool hard outer shell of their body feathers against the air on my own skin. There were at least three species, discernable by their calls: Hooded Crows, which are rather common in the capital, feeding on everything they find in the city. There were Rooks, which have become pretty rare in Berlin, and which travel mainly outward to the countryside to feed, but suffer intensely from an industrial agriculture that has been made plain deadly for all life that are not crops. And there were Jackdaws throwing the occasional mischievous gackle into the coarse screams of the crows. 

In wintertime, huge flocks of crows are a spectacular, albeit still pretty regular phenomenon in the German capital. For some time, I had believed that we were witnessing the whole Berlin crow population settling in our trees. But I learned that there are several of these roosting zones, and they are not always as romantically remote as the one we are visiting in the evenings. There is another huge group, around four thousand individuals, gathering right in the city centre. These birds flock together on a highrise near the Spree river in the hip Friedrichshain/Kreuzberg borough, then start swirling and cawing, and ultimately settle around the Prussian Dome and the construction site of the city castle. 

In the brightly lit city centre the atmosphere is different from the silent forest. But the existential lesson is the same: The world is continuously giving birth to itself, and I can be a joyful part of it. For me, the feeling is even stronger amid concrete, steel, tar, glaring lights and junk, and for many tourists, and birdspotters, alike. Rugged feathers stir the air and create a primordial reaction in the chemistry of the world, a phase shift, where inward experiences coalesce into visible, and audible shapes, and where the sensual presence of bodies creates a space of feeling. We cannot escape this, because that is the principle we are created from. 

There are other roosting places distributed around the city area. The weirdest is inside the central terminal of TXL International Airport. The terminal, constructed in the 1970s, is built as an octogonal shape around an interior open space, mainly for parking cars. In the middle of the car park a massive scaffold made from metal bars raises 20 meters up in the air. From the outside it is covered with oversize advertisements on tarps. The inside belongs to the crows. Several thousand crouch in the metal framework on cold winter nights. 

Around the airport, the birds share the vast expanses of space among the runways and taxiways with the aircraft. They rarely cause trouble—being so smart that they wait to fly across the runways unless a plane has taken off or landed. There is even a rookery close by–the typical multi-nest-colony where rooks raise their chicks (hooded crows, in contrast, breed in pairs). Rooks need the protein-rich diet found on the meadows between the airport lanes (insects, mice, worms) in order to raise their young. On some occasions in the early 2000s, fire fighters have tried to destroy their nests using hoses, but the birds are still there. By now, rooks are strongly protected, and can’t be shot at with watercannons. 

We had laid down. It was chilly, but made it easier to watch the sky. And it made it easier to feel like a part. We gazed upwards, lying on the irregularly bunches of half-frozen grass, our hair making light noises on the soil. The crows were drawn back and forth across the evening sky as though they were fine debris drifting in the ocean, swooshing through a strait, forming eddies at the fringes, combining into loops and pools, rushing past. They floated about as though they were whirling leaves which the autumn has forgotten in a street corner in front of a closed shop, shutters down, and which are taken up by the wind and distributed over the sky. The birds rained through space like ash dragged up from a fire and fragmented by the air, black splinters filing the void. They fluttered about like bats emerging from a tropical cave, from some distance are indistinguishable from bellowing smoke. 

It felt as though the swirling and dashing and dancing crows were the void self-differentiating into solid bodies which each had goals and needs, which each had an own voice and speed, a unique way of ripping apart the invisible silk screen of the air with a knife-sharp loop. And I was thinking that this, the self-differentiation of the void into individuals which each asserted themselves, and which for this self assertion needed the air, and the trees, and the darkness, and the wind, and the others, and us, their admirers, was the reason this whole dance had such a joyful effect on us. 

Something seemed infinitely right. A self-searching and self-finding, a being searched and being found, a reaching out and meeting and being met by another warm body. And at the same time, it was the dance of nameless ragged shapes, a Brownian movement of giant croaking molecules, mixed with some lesser cackling jackdaw atoms. It was both, and it was one through the other: The Brownian molecular movement revealing itself as the self-experience of the huge Psyche which this all is. 

The swirling crows, their raucous cries filling the dome of chilly air, are but one force which reminds us of this. They are a force which we can grasp easily because we have a body as they do. For this reason, as research into mirror neurons in our brains has shown, their experiences are accessible for us because we literally we feel them in our own bodies. But in a larger truth everything is psyche, because everything is body. The setting sun, drowning in an aura of gold and crimson. The shy rustling of wet leaves under our soles. The crisp air, sparkling with tiny droplets, each one making a fine impact on our mucuous membranes. The clefts and wrinkles in the pines’ barks. The cold crystals, composing the soil. 

These kinds of revelations made us, my wife and me, hug one another. Every time we came here on a winter night was a very special insight into. We also needed some warmth. We were there on the damp floor slightly glazed over with icy crystals, staring into the void that filled itself with presence and purpose, because it filled itself with bodies with needs and desires. And then it emptied again. We moved a bit closer, huddled on the forest floor, where we had spent many hours in the long evenings of summer, shone on by the light of the transparent stalks of the tall forest grasses, unmoved, in seeming eternity. 

There it was: the meeting of two warm bodies, which is the source of all newness and transformation you can think of: the meeting of two bodies, two atoms bumping into one another, forming a new molecule, two flakes of ash compounding and building a layer of fertile minerals on the soil, two rooks deciding to settle plumage to plumage in the top of an old pine-tree. Being close to one another in an embrace was nothing different from being part of the eddies and streams that stir pure matter. It was a strange mixed experience of being very much alive and being very much part of a mineral world, the back chilled by the cold floor, the skin tickled by the cool evening mist.

The key to us being able to partake in all this and to know these insights is our body. It is the fact that the crows and jackdaws, as we are, truly are flakes of ash, and drops of water, made of the elements. They, and we, are weight in space that can bump into other weight, change its shape, suffer this change, yearn for expansion, recoil in retreat. We all know how it is to be matter, in all its forms and shapes, as solid soil, as liquid, as air, because we all share being matter. The crows, gathering and mixing, screaming and excited, before settling to close their eyes for a night’s sleep, where a key to the totality behind individual things, and behind my own individuality. 

Stretched out on the forest floor we talked about one of those most famous philosophical papers of the 1980s, which made a huge splurge and became a sort of embodied principle of how a philosopher had to think: Thomas Nagel’s “How it is like to be a bat”. In it, Nagel basically “proved” that we could never know, that we had no connection at all into the bat’s mind. The noble prize novel writer J.M. Coetzee famously refuted Nagel’s rule of thought. Coetzee disagreed with the ensuing general suspicion that humans in their ways to relate to nature inevitably project their inner worlds onto something unknowable and probably emotionless and mute. For Coetzee, we could know what a bat (or a rook) is feeling when it loops over the sky, being full of life, because we know how it feels to be full of life: being full of life is living in joy. 

Lying there under the constant rain of coarse calls, emanating from the whirling ash fragments populating the void, I thought that we should push Coetzees refutal of Nagel a bit further: We even know how it is to be matter, because we arematter, and being matter, we know how it feels to be matter, as our feeling is one reality of being matter. So, we know that to be matter means to be in full life, and full life means joy.

From this angle the crows are the air, they are not different from it, but one of its ways to be, or rather, to desire itself. The crow-being discovers something in the air that no other can, and at the same time reveals that all that moves, and swirls, and transforms, hence that all there is, is the same: swirling flakes of matter in a stream that carries them upward, devours them, crushes them, spits them out changed, rearranged, newborn; particles that deeply down are but eddies in the one huge swirl of streaming being; white as driving snow, transparent as the steady drop, ragged and fragmented as black feathers against the sky.

We can feel because the whole is an incessant mixing of bodies and energies, bound together and separated by the drive towards mutual fertilization. We can feel because this material world through uncountable re-arrangements feels every change happening upon it. Everything that happens makes a difference. It brings more or less fertility, more or less self-realization. Everything that happens is a change of the expression on the face which is this world, make the over-encompassing psyche stir. 

Our thought has dismissed the clairvoyance of older times when men were convinced that the visible was a sign of something intelligible, a power with which we could not communicate directly (because it is the same power forming ourselves). The flight, and the calls, of crows and ravens were interpreted by roman augurs, who would be summoned upon important events, in order to balance an urgent political decision with the bigger cosmic forces. To do this, the priest, the augur, would design a rectangle in the sand, or in a room, and face southeast or east, and watch.

What would an augur, hunkering in the freezing Grunewald Forest, read in the circling birds above? Would he read that it is time to go home and be kind to one another, to be grateful for a heated place to sleep, to be grateful to be part of the vast community of bodies? Would he gather from the caws and croaks that everything has voice, and that everyone is needed to be heard? Would he understand that the whole meshwork of unfolding processes, in which reality manifests itself, is infinitely precious, and invincibly strong? Would the priest resume the message of the black birds in that we need to find less laws and feel more? Or would he just sit in silence and understand that all the birds call for, circling overhead, chasing one another, flocking and dissolving, is a constant current of love towards everything that is, so that it can hear itself, be heard by the others, and continue unfolding?

Huge flocks of crows such as the one I am visiting in the evenings pale in comparison to how many of these birds invaded the German capital in the 1970s winters. Ornithologists assume that then there were 60,000 or more crows gathering in various parts in the city. But in the last twenty years the numbers have crashed. The rook population halved between the 1990s and the early 2000s. Today, the TXL airport rookery is the only one left in the city. The number of Hooded Crows broke down as well. It declined between 2004 and 2014 by a factor of four or five, leaving about 5000 breeding pairs in the city, for now. According to the ornithologist Hans-Jürgen Stork, who for many years led the NABU, the major german nature protection NGO, this is due to massive breakdowns in crow populations farther east, which once all gathered in the German capital in order to survive the winter. Industrial agriculture has cleared the life off the lands even there, in Poland and Russia. 

Is the stirring of the soul we were witnessing as the air sang with coarse calls doomed to stop soon? Can we humans exist without soul? I am afraid that as we are sending the crow peoples away, we are not only impoverishing ecosystems, disrupting foodchains (hence ultimately weakening that on whose receiving end we sit). We are not simply destroying an individual way of being (the trickster-style of the folks of the Corvusgenus). We are directly interfering with soul. We are messing with our own soul, shrinking our own psyche, as this is not separate from the huge encompassing one (which ecopsychologist David Abram so aptly labels the “more-than-human-world” https://www.humansandnature.org/to-be-human-david-abram). We are ruining soul, and with it the chances that soul replenishes and rejuvenates from the desires of its body, which is matter. If we stop granting these beings space, they will go, and they will make the emptiness in ourselves to unbearable to survive. 

Anthropologists know that Native American peoples held the crow and raven people in high estimation as genuine shamanic beings. They are superiorly intelligent (ravens pass the mirror-test of self-consciousness with ease), and in this intelligence so seemingly human, that they became the shamanic bird par excellence, obtaining a middlesman role between the normal world and the realm of the spirits. In the european folklore, a witch is accompanied by a raven. The familiar sits on her shoulder, chatting about the apt sorcery formula to apply, being by and far more intelligent than his half-human company. 

There is a saying from those native peoples which sheds a light on what I intend when I say that if we destroy the manifest self-searching fertility, we inevitably destroy soul, and in it kill our own. The Sioux people, I have been told, think that if we do not express gratitude to the other beings with whom we share our breath, they will return to the world of the spirits. They will leave us, and we will remain, in silence and emptiness. Recently we have been told by top level entomologists that all the insects in the biosphere will have vanished in hundred years’ time. The Sioux view of our responsibility for the psyche of the world, and our failure to assume it, to me seems the sharpest explanation for what is happening. We cannot separate inner and outer realities. To pretend to be able to do so was a deadly mistake from the beginning.

Soul yearns for fertility wherever it settles. It is able to create a home wherever it is constrained to roost, and will do so, until it is completely destroyed. But still then, the principle of soul as the center around which reality unfolds is indestructible. Psyche is the primeval force; the world ceaselessly shuffles its fragments, allowing them to meet and combine, to be cast in new configurations, to overlap, cross-breed, creating fertile transformations where before were none. Psyche is not in particular need of humans. It plays them out and melts them to other forms, other fragments, other compounds. It likes to mold stones and splinters as eagerly, and with as much fervour of feeling. It can wait until universes have formed and contracted, and formed again. It knows no time, only desire, which is the source of all time.

Silence fell over the barren trees. We were seriously cold. The birds had vanished into the trees. Here and there we could hear a faint hustling where a bird was readjusting his weight on a branch, flapping wings, making the silky primary feathers rustle, rubbing his plumage on the bark or on another bird. The silence had come suddenly, as moments before there still had been considerably rumour in the sky, calls here and there, singing feathers. The decline in numbers from many hundreds birds flying to only few dozen had been nearly unperceivable. The shift from only a few to none was clear cut.

We heard some low-frequency stirring beneath the trees and knew that the wild boar were beginning to move out. We stretched our numbed limbs and pulled the bikes up from the forest floor. Also, the poodle stretched, front down and back elevated. While we had observed the birds, she had sat on her hindlegs, staring into the dark forest, as though expecting a large beast to emerge from the shadows. 

We turned back in silence, headlights off, as our eyes had adapted perfectly to the darkness. As we rode along, softly bumping over roots half-raised from the soil, birds stirred in the trees overhead. Our passage left a wake of sound, a fine rustling of feathers, a sparkle of soft bodies. We moved and the world stirred, and folded back unto itself.

We stopped as we reached the end of the forest. For a few moments we could not see in the bright electrical lights. I switched on the headlamp, pulled the dog up under my arm, kissed my wife’s lips still so very warm. A kiss was probably the most accurate shorthand to the immense exchange of bodily encounters engendering transformation and making things able to blossom. The most permanent gesture. I said a silent thanks to the spirit of the forest, to this sensual manifestation of the all-encompassing soul.

Community gardening and urban agriculture are not synonymous. Although community gardens can be important agricultural sites, certainly not all gardens focus on food. Instead, community gardens are community-managed open space. Thus, they can serve as recreational space, open space, performance space, food production space, gathering space, cultural space, or many other functions. Picture a Venn diagram: some gardens produce food (but not all), and some urban agriculture sites are community-managed (but not all).

Since the fiscal crisis and large-scale property abandonment and disinvestment of the 1970s, New York City has one of the largest and most robust community gardening programs in the world, with a broad base of resident engagement in the creation of beautiful, safe, meaningful sites of neighborhood cohesion. The garden history in New York City reflects a pattern that we see trans-nationally: vacant land, re-appropriation of land, and contention over temporary use of land occur in many cities across the Global North and South. Currently there are approximately 600 community gardens citywide and approximately 20,000 gardeners citywide (and this does not include the hundreds of resident gardens on New York City Housing Authority land).

Since the 2000s, there has been a rising wave of interest in urban agriculture and growing food in the city. New York City has new rooftop farms, urban farms, school gardens/greenhouses, backyard chickens, beekeeping and generally high media attention and excitement surrounding urban agriculture. Urban agriculture is presented as one of a suite of strategies for helping to address both the crisis of obesity/diabetes as well as issues of food access, security, and hunger. Again, this pattern is not unique to New York — we see a resurgence of urban agriculture in both growing, global cities where land is at a premium (the Bay Area, London) as well as in shrinking cities with abundant vacant land (Detroit, Cleveland).

Recently, funders, policymakers, and activists alike have organized around a ‘local and regional food systems frame’ that positions urban agriculture as a form of local food production, and part of a larger cycle of food production, processing, distribution, consumption and post-consumption. In New York City, food systems planning and urban agriculture made some modest policy inroads via the work of former Manhattan Borough President (now Comptroller) Scott Stringer, former City Council Speaker Christine Quinn, and former Mayor Bloomberg. Many other cities have created zoning rules related to urban agriculture or have full-blown food policies.

At the same time, we can draw attention to the fact that nothing is so new about urban agriculture; it is part of a long lineage of people growing food in cities that occurs across time, space, and cultural context. This work has been done for decades with little fanfare in the press and policymaking circles, which raises all sorts of questions about inclusion — why now is agriculture so appealing? And might it have to do with the demographic profile of some of the current wave of participants in the practice (young, white, college educated) as compared to gardeners and farmers from low-income communities of color? Within the food justice, food sovereignty, and local food movements, there is frank and productive dialogue occurring about how to build and sustain an inclusive and anti-racist movement.

Moreover: what is potentially lost or obscured by this enhanced attention to food?

Many community gardens were created to promote neighborhood stabilization first and foremost. In many cases the growing of plants and crops was more of a means than an end. By casting community gardens whole cloth as part of urban agriculture, there is a danger in the production of food eclipsing the many other important reasons why we might want gardens (or even farms!) in the city, such as education, empowerment, and cultural heritage. Indeed, many of the current practitioners of larger scale urban food production recognize that one of the most valuable contributions of these sites is to educate urban residents about agriculture and ecology. These sites are inherently multi-functional and are about much more than just ‘food production’. So while a food systems approach allows for elaborate coalition-building and plan-making, it is important that we remember the nuance and history of gardening in the city that long precedes the current wave of interest in hyper-local food.


Joana Chan & Bryce DuBois

Community gardens have long served as buffers to crises in cities. Victory Gardens during World War II not only boosted morale, but also produced nearly half of the fresh vegetables and fruits consumed in the U.S. at that time. During the 1970s and 1980s era of urban decline in New York City, community gardens blossomed to reclaim vacant lots into verdant grassroots community spaces in low-income and high-crime neighborhoods. Forms of urban agriculture have thus served as community responses to times of change and need, or manifestations of “local resiliency,” where residents respond to food insecurity and foster community and individual well-being through their gardening practice.

However, what do community gardens offer to cities in the face of natural disasters? This question guides our research on the role of coastal community gardens in Post-Hurricane Sandy New York City. Unlike previous socio-economic disturbances, food provision, for example, was not a major community garden function in Sandy “red-zones” because they had been flooded with water, sand, debris and sewage. Instead, what we learned was that community gardens served as safe, open community spaces after the storm ravaged the city in October 2012.

The combination of public accessibility and the personalized nature of community gardens contributed to the function of these spaces as local havens during the distress and disorder immediately following the storm. As safe community spaces, community gardens were sites for neighborhood convening, news-sharing and communal cooking. In at least one garden in the Rockaways, therapeutic healing circles were facilitated for the gardeners and their neighbors. The unplanned, adaptable nature of the gardens allowed for flexible use and appropriation of the spaces for community needs, such as staging grounds and distribution sites for food, clothing and solar- generated electricity. As time progressed, these coastal community gardens became prime sites for engaging residents in volunteer efforts and civic stewardship. Community gardens also served as ideal spaces for art and memorialization, where residents were able to (re)create their narratives of place through works of beauty, meaning and defiance.

One key element that distinguished the function of community gardens from other open spaces like parking lots and parks Post-Sandy, was the fact that they were community-managed spaces with their own communities of practice. For example, in Campos Community Garden in the Lower East Side of Manhattan, gardeners mobilized after the storm to help ensure the well-being of local residents, some of whom were stranded without electricity, food or water.

The intimate connection with nature that gardeners had developed through their gardening practice helped some to accept Sandy as an inevitable force of nature, and to move forward in recovery and in the implementation of infrastructural garden adaptations, such as preemptively pruning vulnerable trees and installing raised beds made of stronger, longer lasting materials, to prepare themselves and their neighborhood for future storms.

Sea level rise and extreme weather events like Superstorm Sandy will become increasingly common in our new climate change reality. While community gardens are certainly not the sole method for increasing resilience to all social-ecological disturbances everywhere, our study has shown that they can serve as adaptive local spaces which foster important social networks and provide meaningful opportunities to rebuild social and ecological communities after natural disasters.

A self-disclosure: I didn’t start out loving urban gardening and agriculture. I learned to love them. I am not a gardener. The last time I visited a farm was in the first grade…to see where milk came from. These are not the words of an expert in micro-lettuces.

I have a different passion: cities. We are lucky enough to live and work in the midst of a profound urban revival. A decade ago I hoped cities would “come back”. Today I aspire to cities that nurture an ever richer diversity of people, ideas, and experiences. When asked “What can cities hope to get from community gardens and urban agriculture?” A decade ago I would have replied “not much”. Today I see them as potent tools for helping us realize the unfolding potential of urban life. For example…

—America may pride itself on its commitment to individualism, but for six decades we produced mostly one-size-fits-all choices for the building blocks of quality of life such as housing, workplaces, and entertainment. Today reinvigorated cities make life better by offering multiple choices that support multiple lifestyles. But cities also constrain choices, and limited access to nature tops the list. Voila: urban gardeners and farmers invented the opportunity to toil in the soil on rooftops, in community gardens, and on vacant lots.

—In 1960 my city, Boston, was 96% white and consisted of homogeneous or segregated (pick your word) neighborhoods that found community naturally in churches and schools that residents shared. Today Boston is a majority minority city with few places that bring us together, searching for community in the midst of diversity. Urban gardening and agriculture represent a growing source of community — inviting people to cross racial, economic, and other lines of separation to become neighbors. Just as valuable for our increasingly privatized city, gardening and farming are reintroducing the concept of working together and sharing the benefits.

—Cities are made of buildings, public spaces, and infrastructure built to last for 30 years or longer. Meanwhile the people they house, economy they serve, and culture they celebrate change constantly. Today our society…and even our environment…are evolving at a record pace. Urban gardens and agriculture were invented by people with the fortitude to adapt cities to their own passions. When they look at building roofs, shade structures over parking lots, even the walls of buildings and see gardens and corn fields, they are contributing to a personal urbanism that teaches all of us to draw on our own passions to see and reshape our cities. These passions generate the ever changing magic of urban life.

But the influx of people and dollars that fuel urban revival come at a cost. Displacement is real. For the first time in America’s history more poor households live in suburbs than cities. Equity is not about stopping the influx of affluence into cities, but empowering people to share in its opportunities. As Growing Power in Milwaukee and Chicago demonstrate, urban gardening and agriculture are also about cultivating entrepreneurship, training kids and refugees alike for jobs, and relieving food deserts.

I never thought an urbanist could learn from a farmer. I was wrong.

Cities from around the world can expect a lot of great things from the generalized practice of urban agriculture by their citizens, but local authorities need to recognize these benefits. Urban agriculture is a complete toolbox to build sustainable and more resilient food systems and cities. By reconnecting people with the natural cycles of food production, urban agriculture open the doors on responsible consumption and forces us to question on what truly is sustainable. When people start growing their own food, they often face questions about food production that they wouldn’t even have considered when buying from the supermarket. Is that food safe? Is it nutritious? Should I use chemical fertilizers? By getting people together, community and collective gardens allow people to learn how to grow food, but more importantly, to engage and participate in their community. They engage in a movement that places great emphasis on civic education and community celebration around every aspects of food. More than just about quantities, people grow their own food because they want quality — quality in flavor and nutrition.

Quebec parliamentWhat started as a disaster response here in Montreal’s southeast in 1974 became one of the first and biggest community gardens program in North America, with more than 25 hectares of gardens today. With this growing number of citizens and community organization’s initiatives in backyards, on balconies or on rooftops, other types of urban agriculture gardens appeared in the last few years. Institutional gardens on university campus, in schoolyards and even in front of Government buildings like the Parliament Building in Quebec (shown left) are becoming common. A growing number of businesses gardens or new enterprises are also appearing on restaurants, hotels and offices throughout cities. While some are dedicated entirely to food production like the Lufa farms (the world’s first commercial rooftop greenhouse), others do it for the environment, for fun, to complement their cooking, for the benefit of their employees or food banks (below, the rooftop garden of the Santropol roulant in Montreal).

Santropol roulantComing out of our backyards and dedicated infrastructures like community gardens or other group endeavor, urban agriculture’s next steps will have to be in the broader public realm. With clear definitions and understanding of urban agriculture and its components, policy makers and planning authorities have the power to innovate and provide an optimal framework that takes account of cross effects of urban agriculture (meaning that incorporates various effects such as urban revitalization, job creation, promotion of culture, integration and social participation, public health, waste management and nutrient cycling, biodiversity, and much more). A productive city that focus on human scale urban density and integrate urban agriculture into neighborhood design can generate creative solutions and offer a high quality living environment that contributes to food security and creates opportunities for participation to all members of the community.

Urban ag effectIn a medium density city such as Montreal, there is more than plenty of space for citizens to grow a large part of their fresh food needs. Projects like the Incredible Edible inspire and take pride in using these public spaces to grow stronger and more resilient communities.

In that sense, I do think the sky is the limit for urban agriculture.

Urban agriculture makes a real contribution to the urban food system in multiple ways. The benefits are not just about net food produced. As an example, urban agriculture assists in “repairing” what Nathan McClintock terms the socio-ecological metabolic rift, or our socio-natures. Such benefits for urban residents are not disputed. However, seeing urban agriculture as the primary solution to the urban food challenge is problematic.

The current global food system is a key driver of negative global environmental change. In a predominantly urban world, the consumptive nature of cities is therefore a key force precipitating this change. It is clear that cities need to play a role in retarding this change. Is urban agriculture the solution? No, it is not.

In considering the motivation driving calls for urban agriculture, Battersby noted a distinct anomaly: In Northern cities urban agriculture is predominantly described in terms of the socio-ecological benefits described above. However, when urban agriculture is advocated for in Southern cities, the benefits described seldom go beyond poverty relief, economic opportunity and notions self motivated development. This dichotomy requires deeper analysis.

Universal calls for urban agriculture assume a measure of homogeneity in how cities are considered. Such assertions miss the stark differences in development, governance, economy, geography, structure, location and climate, to name but a few. Even within Cape Town, for example, despite being one of the only South African cities with an urban agriculture policy, economies, micro climates and geographies mean that different approaches and motivations apply in different parts of the city.

Universal calls for urban agriculture “as the solution to the urban food challenge” obscure deep systemic issues within the wider urban food system. When the challenges of food insecurity are considered, assertions that through urban agriculture, the “poor” can counter the challenges of poverty and constrained food access, miss deeper considerations of the structural and governance nature of such predicaments. Such calls perversely place the responsibility on the poor to create the solutions without questioning the drivers of such predicaments.

The espoused benefits of urban agriculture also require some interrogation. There is an emerging body of literature that challenges the often argued extent and scale of urban agriculture. Different cities reflect different levels of urban agriculture uptake and derived benefit.

Changes are required in the structure, governance and impact of the overall food system. Urban agriculture is just one component of far wider urban food system restructuring.

Arguing urban agriculture as the solution to the growing urban food challenge can be likened to the notion that planting trees will resolve climate change. Both calls are actions with a measure of utility, enabling action at an individual scale. However, when these actions are offered as the solution, they divert attention from deeper, critical examinations into the systemic drivers of the challenge.

By seeing urban agriculture as the only solution to the urban food challenge avoids considerations of the imbedded drivers of the food system challenge and could precipitate greater ecological and food system instability.

The first thing that struck me upon entering Miami’s Little Haiti Community Garden was its tropical luxuriance — a community garden with bananas, papayas, coconuts, and sugar cane was something novel. As we wove our way along the winding paths, Prevner Julien looked up from his freshly composted bed to greet us in halting English. Then we sat down underneath the sprawling banyan tree with Gary Feinberg, who along with New York to Miami transplant Tamara Hendershoot, owns the 1/3 acre garden lot.

When Gary and Tamara purchased the lot in 2004, they envisioned reproducing the New York model for community-engaged, allotment style gardening in Miami. Their start was on target — volunteers worked for two months to remove the refrigerators, tires, and other trash piled 8 feet high in the back corner of the lot. Now the lot was ready to plant…except for the fact that they found high lead levels in the soil. Over 50 volunteers helped to bring in clean soil and manure to build up the beds. The soil was now lead-free, but counter to what Gary and Tamara had envisioned, the volunteers had lost interest. So the vacant lot laid vacant a while longer.

After the 2010 earthquake in Haiti, Gary received a call from Medishare. The non-profit wanted to bring a boy who had suffered a serious head injury for treatment in Miami, but needed work for his father. Together Gary and Medishare secured $4000 from the Miami Dolphins Foundation to employ Prevner Julien. But would employing one gardener make any real difference to the Little Haiti community?

My visit to Little Haiti was a lesson in the sky’s the limit for community gardens. That is, if we envision the sky as a horizon — and believe that change limited by the level of the horizon is important. Even though the garden has adapted its original community engagement/allotment vision, and now focuses on one employee producing food for sale (sales provide 95% of the funds to maintain the garden), it still helps to sustain a broader community. Neighbors come to buy collards, kalaloo, Malabar spinach, and papayas — and all sorts of Haitian herbs that Prevner mixes up to treat ailments. Adults and school children learn about four square gardening and permaculture, and a plan for growing herbs to be distilled into bitters is in the works. As we listened to Gary’s stories, a woman walking by peered through the fence and commented on how beautiful the garden was — just like in Haiti. And Rémi stopped in to ask if he could volunteer; Prevner immediately assigned the Parisian newcomer to Miami the job of hauling compost.

In short, Little Haiti Community Garden is a demonstration of how community gardens adapt to opportunities and challenges — along the way inventing new approaches to address their tripartite mission of cultivating community, food, and nature. A community garden in Toronto provides a haven for Afghani war refugees; in post-conflict Monrovia women gain a sense of empowerment by growing food for their families; in Sacramento Hmong refugees recreate place through growing vegetables from Laos — across the horizon community gardens are hotbeds of “grassroots” and “social-ecological” innovation. And they adapt as social and ecological conditions change, continually reinventing themselves.

But the horizon is limited — community gardens operate at a very small scale — often the size of a single city lot. If the sky is the limit, then the question becomes: “Do community gardens have the capacity, not only to dot the horizon with small patches of community and green, but to scale up to address regional, national and even international governance and environmental issues?”

Not infrequently, one of those dots on the horizon has an impact that reaches for the sun at high noon. Here are several “limitless, sky overhead” examples.

—Community gardeners in the Bronx learn about decision-making and democratic processes, and become empowered to get involved in broader food justice issues.

—Community gardens provide evidence of collective efficacy — that someone cares. When neighborhoods demonstrate collective efficacy, crime decreases.

—Community gardens in Bosnia-Herzegovina bring together warring sides of the former Yugoslavian conflict and thus have a role in peace-making.

—Community gardening is a part of larger civic agriculture, slow foods, and civic environmental movements — together they can impact policy change. (Witness Michelle Obama touting the benefits of community gardens on the White House Lawn.)

Little Haiti Community Garden transformed its original mission of reproducing New York’s community engagement/allotment model for community gardens to one that uses paid employment, and fruit, vegetable, herbal remedy and even bitters sales to build a sense of community. It demonstrates that community gardens are able to adapt and transform when faced with the unexpected. Such adaptive capacity and ability to transform are critical in face of future and unexpected stresses, including those brought about by climate change.

Many citizens are adopting healthy and eco-friendly lifestyles, and also trying to put forth their green thumb to have a better environment in cities. Cognizance of benefits that patches of greenery could provide, empathy towards loss of green cover in rapidly urbanizing cities has motivated the citizens to contribute towards a greener environment. Traditionally gardens were mostly cultivated for producing fruits, vegetables, flowers or medicinal plants which come in a variety of sizes and setup. People are getting highly creative and innovative now a days, and they try to make the best out of the limited spaces provided within most of the households. This has led to a sudden rise in a variety of gardens within constrained spaces in an urban environment.

The concept of urban farming is not very new to a city like Bangalore. There has always been local produce of fruits, vegetables, greens and flowers to meet the needs of consumers. Such produce is sold in a ”Santhe” (local market setup by farmers) which cater to the locals on a weekly basis, and are favoured by consumers over the ones from regular stores due to the fact that they are farmed organically and harvested fresh from the farms. This type of market not only supports and encourages the local farming community but also keeps our city sustainable. This might not be sufficient to meet the needs of an ever growing population of this city as rapid changes in land use will affect the productivity in terms of quality and quantity of local food produce.

While large scale farming is one part of the story, the gardens on roof tops, terraces, balconies, community gardens or even spaces as small as window sills for greenery have become increasingly common. Gardens have always been an integral part of almost every household in Bangalore, mainly serving as space to grow plants and trees for food, medicinal or religious purposes. In our research study on home gardens, we found a high diversity of species, about 300 species of trees and plants. Majority of the species were ornamental, but about 40% of the plants and trees were grown for food, medicinal or religious purpose which was really impressive. And, most of the residents don’t use pesticides and herbicides for their garden.

Many forums and conclaves have mushroomed for budding city gardeners, providing them a common platform for exchange of ideas, sharing knowledge and experiences on urban farming. Practices such as innovative space utilization techniques, seed exchange and composting at home are making people share the resources and provide support, building a strong community with large networking. In the near future, for a city like Bangalore there is a good potential to develop community gardens and increase its green roofs not only to reap benefits of supporting, provisioning but also to a certain extent regulating services of our ecosystem. This contribution may not seem like much of a consequence, but if everyone in the city contributed their own green bit towards this cause, it will make a remarkable change in the landscape.

Not until I saw many flowering plants, vegetables and fruits like mango, guava, custard-apple, lemons and also sometimes maize or sorghum all growing happily in my own balcony, under my mother’s tender care and love, that I started believing that there is no limit to what could be grown in an urban environment.

In New Orleans after Hurricane Katrina, most of the houses in the Lower 9th Ward were vacant, many blighted. And many, many empty lots. Most of the residents did not, could not, return. The ones that did had a hard road ahead of them, rebuilding not only their own homes, but a whole community. Because what is community when the people you know are gone and the places you remember are destroyed? Even now, nearly 10 years after the storm, only about 25% of the population has returned.

In 2007, a few residents got together and started clearing an overgrown pre-Katrina community garden. Together, we cut down a jungle of weeds, planted vegetables and flowers, created pathways and formed a garden committee. Throughout, people who had them talked about their own gardens, and told stories about when everyone had something growing in the backyard, and traded produce with neighbors. These stories just naturally emerged. We smiled and laughed with one another, shared with one another. A couple years later, another group of neighbors decided to turn a vacant, blighted lot into a beautiful garden space. And, similarly, these same stories, this same connectivity, naturally emerged. We talked about what we wanted for our neighborhood and how we could have those things manifest in a garden space. We started with just an empty plot of land, littered with trash and tires. And, determined to combat blight in our community, we slowly transformed the space — clearing the land, planting trees, building raised garden plots for residents to adopt, installing a rain garden, and eventually a patio area with a shade structure for community gatherings. With the help of waves of volunteers, we developed a beautiful space in a neighborhood where signs of neglect still outweigh beauty.

Last year, we started programming at the Guerrilla Garden. Six afternoons a week, neighbors come for gardening and cooking workshops, children’s activities, Black history and culture events, community potlucks and other social events. Neighborhood residents have adopted all of the garden plots and grow for their families. School groups take field trips to the garden. And people come just to relax and breathe. It’s by our community, for our community. *We are now in the running for a $20K grant to continue our programming and re-start our youth internship program. Anyone can vote for the Guerrilla Garden to win at www.seedsofchangegrant.com, daily through April 21st.

Backyard Gardeners Network was founded on the idea that the cultural tradition of growing food in the Lower 9th Ward is worth preserving because it creates more than just food. And there is something magical about a community garden. It’s a perfect community project. Any and everyone can be involved, no matter your age or skill level. Those who garden on their own feel strengthened and supported, just being in concert with others who share their passion. And when people get together and work on a project that benefits more than just themselves, they feel more connected and more proud of the community in which they live. They get the satisfaction of knowing that they contributed to making the neighborhood a better place. Garden spaces like ours are essentially open-air community centers, where food is grown, neighbors meet, skills are shared, and people just have a good time. And even passersby gain a sense of hope and joy, seeing a blighted lot transform into a fabulous community greenspace. Finally, everyone eats! So even those who haven’t gotten their hands dirty can still enjoy the wonderful food that is grown. Community gardens brings everyone together, and are often practices in self-determination. In neighborhoods like the Lower 9th Ward, still recovering from disaster, the things that emerge from creating and maintaining a community garden are the things that hold a community together.

Let’s stop confusing apples and oranges: but we like them both. ‘Community gardens’ and ‘Urban agriculture’ are not the same thing.

The initial provocation for this panel is questioning the value of these two aspects of urban life, suggesting they are synonymous, which they are not. I think differentiating between them is important to assessing their value.

Community gardens are a fabulous manifestation of ‘the commons’ — of how neighbors can come together to create a shared resource that delivers multiple benefits for them that they couldn’t possibly create by themselves. CGs beautify a vacant lot, provide respite in a dense urban environment, provide opportunities for spontaneous interactions and also more formal meetings, enable people to express their aspirations to grow or create something that nourishes them (figuratively and literally) and others. A vibrant community garden makes commensality — one of the great gifts of urban life through the commons — possible.

Urban agriculture is something else altogether. It’s about growing food within the city, at a scale that has the potential to put a dent in food security challenges. Scaling up growing food in cities is a laudable goal: but this idea needs to move from a quaint aspiration that mainly takes root in shrinking cities in North American where urban neighborhoods have been abandoned as the industrial economy has vanished. In those cities, re-pastoralizing parts of the city landscape may make sense, in the short and intermediate terms. But in dense urban environments, in rapidly growing cities in the global south and north, what makes more sense is integrating productive planting into everyday urban design. Edible landscapes, such as fruit trees along greenways and in parks, green roofs on residential and commercial buildings, living walls — these can be imaginative interventions that deliver many ecological benefits as well. But I think we need to be realistic about urban land uses and remember that density is crucial to making a city work — economically, socially, culturally and environmentally. So setting aside wide swaths of land for ‘agriculture’ in a contemporary city doesn’t make sense in the long term, because it defeats density. As an interim use — while the local economy develops and will eventually need that land for development purposes, ok.

Here is what I see as the potential of both: as forms of urban acupuncture, a term coined by Jaime Lerner, former Mayor of Curatiba, to describe the potential of hyper local interventions that can catalyze city building. Community gardens enliven neighborhoods and help cultivate local resilience. Urban agriculture, as a transitional use where the demand for developable land has slowed, makes sense. But it is no panacea: we need city builders around the world to continue to look for ways to integrate food growing into everyday life, in denser and denser urban environments, and find ways to integrate and embrace nature in cities within a livable and resilient urban built environment, not in place of one.

When it comes to tools of trade in the urban arsenal, I believe community gardens come very high on the list of “must haves”, and for a very interesting reason. In many ways, like mothers of large families, community gardens multi-task, and that is why the proponents of so many different disciplines support and praise them.

—CGs reclaim abandoned plots within neighborhoods, beautifying them and making them useful for residents, and even upgrading land value

—CGs enable residents to grow some of their own food, whether for enjoyment or as a needed source of nutrition

—CGs provide healthy outdoor activity

—CGs serve as a meeting ground, where there is non-violent interaction between different age groups, different faiths and different cultures. The setting of a garden has proved beneficial.

—CGs fulfil an educational role, so we can understand and appreciate that our food does not grow on a shelf in a supermarket.

—CGs can be excellent community compost drop-offs, and the excellent organic compost produced can be used to fertilize not only the CG itself, but also the residents’ gardens and potted plants. Organic waste is 40% of the total waste.

—CGs can talk to each other and generate a city-wide discussion and interaction

—CGs help restore nature, so birds, bees, butterflies, frogs and insects will all come back if invited by a colorful and healthy garden

For many residents community gardens are an extension of their community center, or an appropriate setting for parties and celebrations, such as weddings and birthdays, to name a couple…..

From multi-tasking community gardens to a city that is self-sufficient in growing its food is a long jump. Experts may well be able to prove that even if we coordinate perfectly, and utilize every possible open space in the urban and peri-urban areas, we can’t grow all we need. Does that mean we shouldn’t try to grow as much as we can? Of course not. Making people aware and respectful of what is invested in successfully growing food could play an invaluable role in making people environmentally responsible.

In my city, Jerusalem, local agriculture opens up an additional opportunity, to restore ancient agricultural landscapes and practices, using the terraces that have survived from the time of the Second Temple. Many urban open spaces are neglected and abandoned, begging to be taken over for the purpose of local farming and food-growing.

I honestly believe that the sky is the limit for urban agriculture, as long as the diverse stakeholders in and around the city are fully engaged with the process. The network of urban foodgrowers can include individuals that want to use their gardens, roofs or walls, community groups and cooperatives, periurban farmers, schools, senior citizens’ homes and others. The network can be coordinated through the municipality, through non-profit networks, or as a purely business framework. In Jerusalem, where 50 community gardens are already growing a lot of food, we are currently initiating an urban agriculture network, to see just how much food we can grow locally, and are waiting to see who will come on board. We hope that growing food together will be a way of finding common ground, in more senses than the physical, for the diverse communities that share Jerusalem’s public domain.

To begin with, the limits may be with the phrase “urban” agriculture. Agriculture, especially sustainable agriculture, works best described as an ecosystem of the region’s foodshed, watershed, energy resources and population patterns with as little divide between people in the various locations as possible. After all, how often do we talk of “rural” agriculture?

In the farmers market revival that started in the 1970s, the earliest markets were often in the university towns of America, but were founded by rural and periurban back-to-land farmers. The very idea of requiring all vendors to “grow it to sell it” was meant to remind urban citizens about the farmland that lay near enough to see, but maybe not close enough to smell or to taste any longer and to reintroduce those who toiled happily at that work too. Or as Wendell Berry wrote, (to know) “farming as the proper use and care of an immeasurable gift.”

Unfortunately, the astounding growth of farmers markets has not rid most of the country of its ill-conceived perceptions of rural people and farmers as lacking sophistication or of their of willingness to create a new world. So, the bulk of the work of community food systems remains ahead: to redefine wealth creation for producers, and increase the health (mental and physical) of the entire community that it serves. And yes, urban people working in agriculture must be part of that future. They can help by testing innovative farming strategies in their yards and on their rooftops to then share with their rural colleagues and by allowing agriculture to be seen, smelled and experienced in their neighborhood.

If we spent our energy organizing and connecting everyone with experience and/or the desire to farm with little or no regard to socioeconomic status or to location, we might then have a fighting chance to have a system that is direct and fair and able to withstand the inevitable environmental and political damage coming (again) soon.

Don’t take me at face value, go look for the most successful “urban” agriculture initiatives; I bet when you do you’ll find they have a bioregional focus and systems that create opportunities for all comers whether they live at the end of the block or the end of the road.

The Smart (Cyborg) City Needs Smarter Ecological Resilience Thinking

Many voices. Greener cities. Better cities.

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 for instance Luque Ayala and Marvin, 2015: March, 2016; Hollands, 2015). Smart grids and meters, automated transport systems, communication networks, and data collection and analysis of data are all part of the smart city vision. While the seamless integration of digital technologies for the management of city functions promises greater cost-effectiveness and efficiencies, there are significant questions and philosophical issues that must be addressed as greater reliance on technologies for the running of our cities is pursued.

By intertwining systems that generate different kinds of services—creating a system of systems—the complexity of the whole increases exponentially. As a consequence, the vulnerabilities in a smart city system are significantly higher.

This summer over 7,000 papers will have been published about the Smart City. It is by far the fastest growing discourse within the wider umbrella of urban sustainability. Despite the sheer number of publications, none applies a social-ecological resilience lens in the analysis (Colding and Barthel, 2017). We argue in the letter to the editor of the Journal of Cleaner Production that urban resilience scholars need urgently to engage with this literature to provide deeper philosophical pondering about what really is at stake and if and how the Smart City could contribute to development of a more resilient planet Earth.

Employing a sort of a cyborg worldview—meaning a living system of intertwined human and machine parts—the Smart City system is seen as contributing to urban sustainability with the basic assumption that ‘the Internet of Things’ serves social and public ends. These ends include economic benefits, improving efficiency and quality of life for people by optimizing control of infrastructures. In this view, urban residents are at the center of a city’s sustainability transformation, while at the same time serving as “data sources”, providing urban planners (central controllers of the cyborg) various sources of information about human behavior that may or may not be exploited. While various efficiency measures often are beneficial for society, at least in the short term, the discussions of resilience of such a cyborg is mostly entirely avoided (Colding and Barthel, 2017). Fresh in memory is the recent global outbreak of ‘worms’ which in the UK collapsed large-scale critical infrastructures, like hospitals. Hence, it is necessary to confront how the cyborg strategy may affect resilience related to basic social services, including how basic human needs might be secured, i.e. health care and food-energy-water security.

The literature around the smart city concept appears to rest on the idea of environmental modernization, a paradigm placing particular emphasis on enhancing economic and social sustainability. However, this literature puts hardly any emphasis on ecological sustainability, nor does it include the role of ecosystem services, such as those generated by urban agricultures or wetlands and which could be viewed as technologies, for building urban resilience towards internal- and external disturbances. If the concept of technology is understood as the compilation of techniques, skills, methods and processes used in the production of goods or services, wetlands for instance can serve to shelter cities like New Orleans or the mega city of Dhaka from flooding and denudation, and peri-urban food production systems contribute to a resilient food security by keeping prices low when poor city inhabitants suffer from global price-spikes of bulk crops (like the spike in food prices during 2008).

Colding and Barthel in their recent publication in Journal of Cleaner Production (2017) discuss the resilience of the internet (on which the cyborg feeds), viewed to function as a complex adaptive system. They argue that the internet, like healthy ecosystems, holds vast redundancy that is of crucial importance for its resilience, composed of several seemingly redundant elements that are able to perform the same basic tasks. If one task gets wiped out, others can step into its place. The internet also contains modularity of the totality of the network that prevents disturbances to spread easily throughout the system, or web. However, modularity comes at the expense of connectivity; why it is important to strike a balance towards intermediate levels of modularity that promote resilience in social-ecological systems by keeping enough information and genes flowing, while preventing disturbances from spreading quickly. But such structural characteristics single-handedly cannot build resilience. Learning and memory are also vital for building resilience. Unlike the internet, immune systems of humans can quickly perceive attacks and respond by isolating the damage to one part of the system. In this way, the immune system can learn to detect and remember pathogens, rapidly redirect information and energy, redistribute tasks, and increase immediate counterstrikes (Buchanan, 2002). Compared to biological systems, the internet is but “an elephant trying to play the piano”, and a well-coordinated attack may well disintegrate it into isolated pieces.

New markets that develop rapidly tend all too often overwhelm societies capacity to develop new regulations to respond to unwanted surprises. One example is smart city technologies that develop faster than urban resilience thinking, let alone laws and regulations, creating a gap that leaves ample room for industrial espionage, terrorist attacks, worm infestations and system failures due to natural disaster. By intertwining systems that generate totally different kinds of services (e.g., internet with e.g. flood control systems, traffic control and with power grids), creating a “system of systems”, the complexity of such collaborating systems increases exponentially. As a consequence, the number of vulnerabilities in a smart city system is significantly higher than that of each of its sub-systems (Bartoli et al. 2011). There are also “major privacy concerns” to be overcome in realizing smart cities, such as maintaining confidentiality of personal data of groups and individuals (Batty et al., 2012).

The smart cyborg city may of course also offer benefits for citizens; but those are still largely aspirational. There are a great number of questions that must be addressed both in research and more broadly in society through public debate and in the media. Applying a resilience lens, cyber security is likely to become one of the biggest challenges facing the development of the cyborg. We urge social-ecological resilience scholars to make a mark in the booming literature on smart cities. For instance, how can ‘nature based solutions’ complement in resilience building of basic services for human wellbeing, that may be jeopardized when basic infrastructures become wired in by the ‘the Internet of Things’? How can resilience scholars trained in systems ecology contribute with thinking around cyber security? How may Smart City technologies interact with place-making in cities? These perspectives must be a part of the discussion if smart cities truly will become secure, sustainable, resilient and an asset for city inhabitants.

The Sounds and Smells…and Costs…of Urban Ecosystem Servicing

Many voices. Greener cities. Better cities.

Vroom, buzz, roar, hum, zzzz, whine, chuffa-chuffa, whir, putt-putt, growl and shriek.

Acrid, penetrating, sweet, stomach turning, smokey, arresting.

These are the sounds and smells of machines, the machines that fueled by petroleum and are ubiquitous in the urban landscape, seemingly indispensible and unavoidable to the maintenance of urban ecosystem services.  The smallest patches of lawn are mown by gasoline powered mowers, the grass is blown aside by gas powered blowers, hedges are trimmed with gas powered trimmers and gasoline fueled vehicles carry the laborers from site to site so they can deploy the machines to trim, cut, mow and tidy up yards, gardens and parks of all sizes and shapes.

There is little to no accounting for the impacts of these activities, not only for their contributions to criteria air pollutants and greenhouse gasses (GHGs), but also for the ways in which they impact the health of yard care workers, and residents.  The noise associated with this work is never discussed: the invasive and pervasive sounds of motors whose decibel levels are poorly (if at all) regulated.  The senses are assaulted by the banal and routine activities involved in “maintaining” our urban green space, ensuring it is orderly and well tended, controlled and clean.

EPA estimates that gas mowers represent 5% of U.S. air pollution, using 800 million gallons of gas per year.  A new gas powered lawn mower operating for one hour produces as much volatile organic compounds and nitrogen oxides as 8 new cars each being driven for one hour at 55 mph.

EPA also estimates that over 17 million gallons of fuel, mostly gasoline, are spilled while refueling lawn equipment each year—more than all of the oil spilled by the Exxon Valdez in the Gulf of Alaska.  One gas mower spews 88 lbs of CO2 and 34 lbs of other pollutants into the air every year.  And these numbers do not account for the fuel necessary to create nitrogen fertilizer and the impacts of the use of that fertilizer on water quality and soils in cities.  It has been estimated that more nitrogen fertilizer is used in cities than for agriculture in the U.S..

The perception of what constitutes the proper nature in cities certainly contributes to this sensory landscape.  We are accustomed to an urban nature that is manicured and orderly, contained in both size and shape—no overhanging bushes or vines that could intrude on passageways—pruned up trees so trucks and cars can whiz along.  Things are rectilinear and symmetrical.

Now, this is probably an over generalization, but nature in the city is contained and restrained so that it does not interfere with the free flow of commerce and movement, thus neither invasive or over bearing, nor wild or feral, except in reserved and controlled spaces.  Lawns serve as out-of-doors wall-to-wall carpeting, ensuring cleanliness, covering soil—dirt—creating a sanitized green covering of what might have been originally the substrate for a mixed flora and the home of insects, microbes, birds, mammals and amphibians.  Now instead there is turf, grown at turf farms, cut out and laid upon soil, then watered, fertilized, poisoned so no weeds will grow, nor any potentially destructive insects can live, and tended by poorly paid labor using machines that require petrochemical inputs.  Critics of this system (Robbins 2007, among others) have pointed out the power of the lawn care industry (and the chemical industry) in creating societal norms about landscape.  Change is occurring, but slowly as it involves not only an aesthetic leap, but also requires new knowledge, new plant availability, and new landscaping practices.

Our conceptual imagination is still challenged by what climate and ecosystem appropriate urban landscapes might look like.  One of the issues is that urban landscaping is rather similar across cities, as Maria Ignatieva wrote in this space.  Lawns and big trees in parks, lawns in front yards (and often in back too), easy to grow and maintain hedges, a few roses perhaps, and shade trees.  But if we were to replace these with more climate appropriate landscapes in cities across the world, the variety and complexity of these landscapes would be extraordinary.  We marvel at the differences in architecture in historic cities, architecture that has been often designed to be climate appropriate.  White, tight cities along the Mediterranean, to reflect the sun’s intensity and to create shaded alleys for human circulation, and cisterns to capture scarce rainfall.  Darker surfaced, less dense cities in the north, with slate roofs, for example, and drainage systems to evacuate rainfall and snow.  With increased interest in vegetation and parks in cities, what would the landscapes look like if they too reflected their biogeography and climate?

For the region I know, California and Southern California, a Mediterranean climate region, urban landscapes would be shubbier, browner in the summer with exposed soil between the plants.  Oaks might punctuate those landscapes, and the palate of flowering bushes, shrubs and ground covers would be not only diverse in size and types of flowers, but profoundly fragrant.  We would have many sages, penstamons, bunch grasses, poppies, ceanothus and arctostaphylus among other wonderful plants.  In the Northwest the landscape would be more mesic, with green full vegetation, azaleas and rhododendrons, and maybe turf grass.  Trees would include firs, maples, madrones.  Imagine the urban landscapes for Chicago, Dallas, Atlanta or Boston.  What wonder we would experience going to those cities and feeling “in place” due to the urban gardens and parks reflecting their regions.

This transformation will be difficult for a number of reasons.  One is the hesitancy individuals feel to change their landscaping when their neighbors have not.  Another is lack of knowledge about different plants and their maintenance.  Finally there is the issue of cost, which I partially address below.  Landscapes are not inexpensive to change, and funding for this effort remains episodic and requires access to knowledge.

Redesigning the landscape of urban ecosystems fundamentally also requires addressing how they are maintained, and by whom.  Today urban ecosystems are by and large anthropogenic—chosen by people and placed in cities regardless of native ecosystems.  They are in that way novel ecosystems, almost entirely the artifact of human choice (putting aside the constraints of climate).  They are chosen for their ease of management and maintenance, for their characteristics of greenness and homogeneity, consistency and predictability, across neighborhoods and parks, and for their responsiveness to mowing, blowing, pruning and trimming by easily available machines.  They are seen as a matter of course today, and only starting to be questioned.  Routinization of maintenance tasks, is important to reduce labor time, and one can even think of these landscapes as nearly Taylorized in their arrangements to be efficiently tended.

In Los Angeles, for example, the Mayor has pledged to open up to 50 new small parks, a good thing.  One of the main criteria for the park landscapes was ease of maintenance—the ability of crews to come in and mow quickly and to move to the next park.  A codified approach to park furniture was also developed to facilitate maintenance.  Thus another important issue in considering urban nature is the question of labor costs and skills involved in landscape maintenance.

For private garden crews, the ability to make a living depends on the number of gardens they can mow and blow in a day.  Machines make that task easier—it is faster to mow with a machine than a push mower, faster to blow leaves and debris than to rake and to sweep.  Machines are also easier on the body—except that the emissions are toxic.  The trade-off is between biomechanical injuries and cancer.

While there is growing recognition of the potential environmental improvements that could be provided by new landscapes that include trees, infiltration zones, climate appropriate plants and so forth, paying for the requisite transformation of the urban fabric and for its subsequent maintenance is a challenge.  Not only are traditional city services like tree trimming being reduced, but the implementation of new approaches that use ecosystem services may need innovative new public/private partnerships to come to fruition.

Perhaps there are other ways to fund the transition away from the petrochemical, water and input intensive current system.  Many urban residents today use gardening services to maintain their yards, the mowers, blowers and fertilizer administrators tending to the grass and flowerbeds.  Depending on the amount of labor and the region, fees for such services vary, but residents from single family homes to multiple family apartments with outdoor vegetation commonly hire gardening services for routine garden work.  This expenditure of private funds for a private service offers a tremendous opportunity to create neighborhood benefits through the establishment of neighborhood improvement districts, similar to business improvement districts.  Such a program could capture the individual private expenditures to implement neighborhood nature’s services infrastructure.  Street trees could be planted and maintained for individual and neighborhood benefit, infiltration zones could be created that would capture stormwater and runoff for groundwater recharge or irrigation purposes, benefiting the individual property and the neighborhood, and climate appropriate vegetation could be planted to better reflect local and regional rainfall constraints.

Not only would the individual property receive the environmental benefits, but if implemented at a neighborhood level, the sum of these benefits would be significantly greater than if implemented in a scattershot way at the individual level: consistent shade along the streets, less flooding or waste of water, reduction water-use and mitigation of potential water shortages, reduction of the use of fossil fuel inputs to mow and fertilize plantings, less pollution and impacts to public health.  Neighborhood associations could be encouraged to develop these districts.  The use of existing Home Owner Associations is an obvious path, but not all neighborhoods have HOA’s, particularly in neighborhoods of renters.  Alternatively, there might be the possibility of integrating the maintenance of neighborhood-scale ecosystem services in existing landscape and lighting districts that already collect parcel-based fees for local benefit. Non fossil fuel dependent urban ecosystems maintained by neighborhood-pooled resources could be a new and powerful addition to transitioning urban vegetation away from the need to be so intensively maintained.

Using reoriented and pooled private gardening services thus has the potential to provide significant neighborhood level benefits that include:

  • Maintenance of urban trees to reduce the urban heat island effect.
  • The development and maintenance of distributed projects to reinfiltrate stormwater and dry weather runoff.
  • The creation and maintenance of green streets including bioswales, rain gardens, infiltration planters, permeable pavement and other Low Impact Development techniques.  As city budgets are reduced, neighborhoods themselves may be better suited to reconfigure existing infrastructure and to manage the ecosystem service-infrastructure.  This approach will require innovative public/private partnerships since cities have traditionally been responsible for stormwater runoff and water quality, but there are examples of nonprofit organizations building bioswales in neighborhoods that could be the template for future efforts, in conjunction with city government and neighborhood stewardship maintenance districts.
  • Reduction of water-intensive landscaping in planting strips and front yards and to better watering practices.
  • The regular cleaning of stormwater drains to reduce trash Total Daily Management Load (TMDL), other TMDLs and potential flooding from trash-blocked stormdrains.  Budget constraints of cities are making regular maintenance of stormdrain catchment basins less frequent, neighborhood level participation will improve water quality.
  • Keeping green waste on site for mulching—enhancing rainwater capture.
  • The reduction of the amount of fossil fuels used to maintain urban vegetation.  With neighborhood level aggregated ecosystem services maintenance, stewards (retrained gardening services) can be hired to work in adjacent or single neighborhoods, reducing the need to travel across town from job-to-job.  In addition, with more climate appropriate landscaping, fossil fuel inputs for mowing, fertilizers, blowing cut grass and so forth would be diminished.

A Neighborhood Urban Stewards program using the existing garden maintenance workforce for neighborhoods, funded by voluntary “Neighborhood Maintenance Districts,” modeled on Business Improvement Districts, could provide individual and community nature’s services benefits that would greatly enhance environmental quality in neighborhoods.  Cities would have to develop agreements with the Neighborhood Stewards for the maintenance of green infrastructure in the public domain, much like how Business Improvement Districts enter into agreements with cities to provide additional security services, to keep streets in their districts clean, and to plant trees.  Such agreements will vary jurisdiction to jurisdiction.

As cities advance green infrastructure strategies, programs and projects, a skilled workforce will be necessary.  To date, the hiring of many cities has not kept up with the needs of the green infrastructure maintenance it has in place, such as street tree maintenance.  An additional and parallel workforce could be responsible for the maintenance of the existing, and new infrastructure at a neighborhood level, chosen by neighborhood organizations, and trained by local community colleges.  Community colleges could develop a Neighborhood Steward certificate program for these gardeners.  The potential labor force would consist of the current numbers of gardeners who already provide gardening services in cities.  Such a program would provide additional skills and knowledge to an existing workforce in water management and other green, skills and responsibilities.

Neighborhood level implementation is the appropriate scale for such services, as it reinforces neighborhood identity, cooperation and sense of community in the city.  Such services would simply be additional to those rendered to private residences today. Homeowners Associations with dues, Business Improvement Districts with membership fees and dues are existing models for pooling property owners’ funds for mutual and public benefit.  Homeowners Associations in some places already provide many of the traditional municipal services including trash collection and street maintenance.  While different than an HOA because it would work collaboratively and cooperatively with a city, the neighborhood steward organization could be used to supplement city services in the transformation of public and private open spaces.

Pooling funds that are already being expended for yard work to also address neighborhood level outdoor infrastructure is potentially one efficient manner to approach the dual challenge: a new infrastructure and insufficient public funds.

Since there is a large, employed workforce already paid for privately, building on an already existing and compensated workforce to provide the green infrastructure maintenance services needed as cities advance their green infrastructure strategies, programs and projects.

This approach would not substantially increase the costs that residents already expend for “gardening” services.  It could measurably reduce GHGs generated by this sector by:

  • Concentrating the client base, reducing driving from location to location
  • Reducing overall water consumption in cities for outdoor irrigation with watering being done by trained, neighborhood level stewards
  • Reducing the amount of fossil fuels used in maintenance in the city –requirement that for certification, all blowers, mowers and other machinery be electric, or encouraging new landscaping that does not need this type of maintenance at all
  • Increasing the health of the landscape worker, the neighborhood and beyond

Such a program would build on an already existing workforce, provide this workforce with additional skills, offer it an opportunity to organize itself into an association and obtain and offer receive health insurance as an association

It would engage neighborhood level groups and organizations in the management of their own green infrastructure, thereby elevating green infrastructure into their awareness and responsibilities.

Cities would have a workforce of neighborhood stewards to implement programs that currently it does not have the personnel to execute.

Such stewards can be responsible for cleaning stormdrains, but also prevent other pollution that gets carried to water bodies through intercepting bad practices, spills, and other occurrences that they might find.

If existing nonprofits involved in green infrastructure could be enlisted to develop and implement this program, it would offer them an opportunity to further their work in the city.  This approach can also formalize an informal sector.

Introduction

Dada was an artistic and social movement centered in Paris in the early 20th Century. It was—by design—disruptive, counter-cultural, odd, and surreal. One classic Dada action was to hold poetry readings in which all the poems were read at the same time.

That sounds a lot like many “conversations” that we all have, no? At the very opening of The Nature of Cities Summit in Paris (June 2019), we invited the first 13 speakers to the stage. They each delivered a 90 second talk entitled “What is the city of my dreams?” under a slide with the text “This is conversations as they often are”. They delivered these 13 talks at the same time, in glorious concophony. You can read their individual texts in the next section.

But in the months prior to TNOC Summit, they also wrote a collaborative text, serially, one paragraph at a time, with the prompt: What is the nature of the city of our dreams? Under a slide with the text “Conversations as they could be”, they read their collaborative text. There were three rounds of the 13 writers (totally 39 stanzas), and within each round the order was random. Below is video of the entire opening, both the Dada part and the read collaborative text. Further below you can read the full collaborative text, and all the individual texts that each person read in concophony.

On the coming months, more and more TNOC Summit outputs, of which this is one, will appear. Visit TNOC to see them emerge.

What is the nature of the city of our dreams?
A Collaborative Meditation written serially

{Jessica Kavonic} I am from an African city and I work with local governments in African cities. Everyday I engage with rapid changes, complex environments, vibrant people and vast amounts of innovation. These cities must: embrace Nuance, develop New ways of thinking to guide how society works, and Nurture strong relationships.

{Chantal van Ham} If planet earth is our mother, then soil must be our father. Seek the silent places where no jarring sound is heard, and nothing breaks the stillness but the singing of a bird. Nature tells its secrets not to those who hurry by, but to those who walk with quiet heart and seeing eye. I hope that the Nature of Cities movement will grow around the world, to make the treasure of nature and especially soil visible and to restore the connection between people and nature.

{Carmen Bouyer} I dream that it creates the ground for new urban cultures. Opening space for respectful and resilient forms of co-existence between humans and non-humans. Welcoming rivers, wetlands, meadows, forests, plants, animals, natural cycles, rhythms … and the poetic cultures they all nurture.

{Katie Coyne} And how can that poetry of people and nature become magnified by insisting that equity and justice are a part of the Nature of Cities charge? We must be uncompromising in our belief that the best urban cultures and natures cannot co-exist and meld together without ensuring all people can experience it!

{Gillian Dick} I want an equitable, resilient city that empowers its citizens to take ownership of their own destiny in a sustainable way. Sir Patrick Geddes got it right over 100 years ago when he said that placemaking (although he didn’t call it that he called it planning) task was to find the right places for each sort of people; place where they will really flourish

{Cecilia Herzog} For places to flourish, ecological education must start since before babies are born, so all people understand their role in this wonderful world, their interdependence with native ecosystems, and then nature will be in all cities bringing not only sustainability and resilience, but for joy and harmony for all.

{Timon McPhearson} I want to be able to walk up, over, and down buildings coated in ecosystems, where nature is intricately woven into the built fabric of the city, where we don’t have to ask who benefits from urban nature, because we all have equal access to the clean air, cool breezes, and fresh food that it provides.

{Samarth Das} According to astrophysicist Nigel Calder, if Earth were a 46 year old woman, humans have been around for just over half a week, only a minute has passed since man began his Industrial Revolution! Yet in this short time the impact we have had on earth’s environment is irreversible. I dream of cities where people are empowered to fight for the protection and enhancement of these inter-woven ecosystems to ensure a natural as well as political resilience against climate change.

{Andrew Rudd} This will require an immediate infusion of openness and empathy, which are probably the most critical deficits of our entire half week on earth. Without them we will not share with other ‘tribes’, whether these are other ethnicities, other generations or other species.

{Patrick Lydon} And how does one find empathy and openness with other species? How do I cultivate a relationship with a river, with a mountain, with a tree? Does it come when I realize the nature within me?

{Marcus Collier} As cities become more and more populous, and the vast majority of humans are living their entire lives in an urban environment, less and less people will know what wild nature looks, feels, sounds and smells like. A large proportion of people will not be able to afford to visit the wider areas of the planet. So, rewilding cities is also rewilding ourselves.

{Thomas Elmqvist} I dream of cities and the people that live there become more and more the engines of innovations, continuously creating new incentives for sustainable landscape management, so that cities become the hope for the planet.

{Lindsay Campbell} Along with the transformation of our urban landscapes, I dream of the transformation our governance structures. We need to recognize the importance of civic innovation and create meaningful, authentic forms of power-sharing and joint decision-making between citizens and government.

{JK} And building effective multi-level governance. Recognising the vital role that national government play in enabling urban development, the building of a future city needs to focus on ensuring sustainability of activities by matching ambition and action with the mandates held at all levels of governance.

{CH} So we must face corruption to enable all people dream and co-create better urban environments. Otherwise wealth will continue to be concentrated in the hands of a few that control the political arena, and the majority of people will prioritize to put food on the table in the next meal. Social justice is key to transform the urban landscape.

{CvH} We are all from the same planet. Cities are the places where people meet and discover the beauty of diversity and exceptional encounters. They can connect worlds which may seem miles apart, hold the key to dialogue, bridge differences in language, nature, culture and beliefs and are the nursery for creative solutions that will make our world the most amazing home for future generations.

{MC} So we are continually seeking solutions to build the kinds of cities that foster all of these dreams. We discuss and debate novel ways that can citie-makers can be simultaneously creative, innovative and cities can evolve into natural, social, cultural, spiritual, artistic and cohesive spaces. But there is pressure for us to end the debating and begin the actions. It is here that we find ourselves in this Summit!

{SD} A summit where we define 5 key urban goals and thematic pillars that reflect the cities of our dreams—justice, livability, sustainability, health, and resilience. We must begin our actions by discarding apprehensions and inhibitions of engaging directly with our government officials, local area elected representatives and professionals and work together to create equitable and unbarricaded green urban spaces where “Nature” becomes the real client, and all of us—it’s consultants !

{AR} We begin with justice–and justice begins with us. With courage, we confront greed and shortsightedness. We reject the false narrative that barricades work better than flows. And we embrace cities’ offer of contact, camaraderie and common cause.

{TM} We must put equity first. Greener cities that are more sustainable, more livable, more resilient, and more just, must be also inclusive and address our fundamental social inequities to ensure that all lives improve.

{GD} But if we wish to take our communities, whether professional or “of interest”, with us we need to look for Nature Based solutions. We need to ensure  that what we do has clear benefits for the environment; the economy and society. We need to co-produce solutions in a collaborative way. It’s usefully summed up in the quote “Nothing about us, is for us, without us”

{KC} Well-designed cities and places are only great if they maximize the stacked benefits our ecosystems provide. We must look outside our own conceptions of “US” to be vulnerable, to lean in and let go of our assumptions in the spaces where we differ, and to fully realize the total and truly equitable potential of our cities.

{LC} We must also look to many different ways of knowing – to different worldviews, epistemologies, and cultures. Privileging the modernist-rationalist-scientific worldview helped get us into this mess. Let’s acknowledge and amplify other forms of knowledge and ways of being that might help us forge a new way forward.

{TE} Cities must be more aware of the regions where they are located and take responsibility for a sustainable urbanization. This would entail managing flows and interactions in a more sustainable way, and where not only the cities are developing to become more fair, green and accessible but also the whole region.

{PL} Such bioregional awareness gave birth to one of our few examples of a sustainable metropolis. In deciding to give back to nature more than it took, Japan’s Edo-period government also gave individuals, neighborhoods, and villages creative license, so that they could come up with unique solutions for their own regions. Today, here, each of us holds this creative license, too.

{CB} Let’s express our full creativity in answering the questions: How can i best sustain life in the place I live in? How can I give back more than what I took? By each taking time to attune to the wide diversity of life cycles at play in the local landscapes, we can welcome non-anthropocentric creative answers that will reshape the cities we live in.

{AR} In cities we face difference and realize that it is cause for curiosity and celebration. Together we can address the uncomfortable and incomprehensible. We can better consider the impact of our actions on others in faraway places and times. And we can enrich life instead of extracting from it.

{JK} And as we reflect and consider let all these questions posed guide the development of tailor-made context specific solutions. A future city should build confidence of its decision makers. It should practically embrace the complexity surrounding decision making and financial and political influences. Spaces for ongoing learning, knowledge construction, visioning and relationship building are key to solution development.

{CH} Landscape is the stage, the support of all natural and human processes that can regenerate life for all. We need to enhance biocentric, biophilic and love approaches to gather all agents of landscape transformation, aiming to reintroduce native ecosystems in built and non-built landscapes. We must bring along the young people that are already mobilizing the world about climate change to revolutionize the nature of our cities.

{TM} What information do we still need to make our decisions truly able to adapt to the constantly changing nature of cities? We need to harness the rapidly emerging and evolving data ecosystem from IoT to social media data to make sense of what our ecosystems, our infrastructure, and our residents are already telling us. But we also have to understand the ethical challenges this data brings with it.

{LC} And from these data and other repositories of knowledge, how can we visualize the sometimes unseen, but crucial, social forces that shape our urban realm? By rendering these visible, can we better dance with our social-ecological systems?

{CB} “Freedom: Dada Dada Dada, a roaring of tense colors, and interlacing of opposites and of all contradictions, grotesques, inconsistencies: LIFE” concludes Tristan Tzara’s 1918 Dada Manifesto. What we want now is also spontaneity said Tzara: “Not because it is better or more beautiful than anything else. But because everything that issues freely from ourselves, without the intervention of speculative ideas, represents us. We must intensify this quantity of life that readily spends itself in every quarter.”

{PL} Dadada Da Laaaradarara! Radala da da Da DAAAAAA! Da. Da. da da da. Obachan Ojichan. Jijijiji bababa. Jiba la da BA bababa ladaradasa. Oh? Ohsa. Oh SA! Sala dalarada da! Da. Da. Da. La dee da dee da. C’est la vie.

{MC} Dada was a reaction to the social and cultural bourgeois, the business-as-usual, the hegemony of the elites. Cities of the future cannot be bourgeois, cannot have elites. Nature is the great leveller – it treats all people the same; provides nourishment for communities and individuals alike. Nature is irrational, unpredictable and surreal, making nature in cities very, very dada!

{SD} This very unpredictability is what makes it essential to engage with the environments around us- and their various issues- in a holistic way. Our engagements should range from design to pedagogy, from research to conservation, from activism to participation – all at once! In order to break away from the ‘business as usual’ we must blur the boundaries between these various modes of engagements, and ensure that traditional practices perform within expanded narratives of their respective fields. Together, we can bring about the desired, nature-driven change!

{GD} But most of all we must talk in “plain english” , take communities with us and design for understanding and social cohesion working in partnership with the nature based solutions. Does it matter what we call it as long as we all understand why we are taking the actions that we are and that we are all comfortable with them.

{KC} It’s also not just about taking communities with us… we also need to go with communities. We must recognize that one of the largest barriers to social cohesion and collectively improving our cities is fear of change. As much as we advocate for large scale change, we should also be advocates for teaching people how to cope with all scales of change from a young age. Pema Chodron said, “What a predicament! We seem doomed to suffer simply because we have a deep-seated fear of how things really are. Our attempts to find lasting pleasure, lasting security, are at odds with the fact that we’re part of a dynamic system in which everything and everyone is in process.”

{TE} We may have come a long way in embracing a more inclusive approach in identifying the challenges ahead, co-designing what should be our priorities, we might also be on the way to collectively generate, co-produce new knowledge on how to create solutions addressing these challenges. In  my mind, where we have failed is in working together to implement these solutions, the co-implementation where we jointly evaluate and monitor for our collective learning of what works and what doesn’t in each local context.

{CvH} And exactly that has been the vision of David Maddox and Mike Houck, when they started The Nature of Cities virtual platform back in 2012. A network of the brightest thinkers, peaceful warriors, and brave heroes who show leadership and inspire us all to create positive change to the way we work together in cities. And here we are today, for the 1st global gathering, creating new connections, sharing ideas and finding the inspiration to do more than we ever imagined in creating cities that are resilient, sustainable, livable, and just.

UNISON: These are some ideas that we have created together. Thank you.

I am from an African city and I work with local governments in African cities. Every day I engage with rapid changes, complex environments, vibrant people and vast amounts of innovation. But what is the nature of the city of my dreams?

We have been asking the same question to many stakeholders in African cities and they have provide a list of principles that they felt were essential for a future city to adopt. Some of these include:

• Work within context
• Embrace creativity and innovation
• Build networks of intermediaries
• Recognise that informal systems are critical parts of African cities
• Encourage adaptive and flexible policies
• Support regenerative approaches
• Strengthen systems thinking
• Encourage knowledge flows and overlapping research/policy agendas.
• Strengthen coordinated work between multiple stakeholders, sectors, scales and perspectives
• Create diversity – in both the approach to tackling the problem, and the solution

For me, a future African city now rest on the HOW. It is in implementing and embracing new ways of thinking to guide how society works. It is in applying new ways of planning and decision making in order to effectively allow future cities to deal with the rapid changes expected. Future cities need to be solution and action orientated. They should build confidence of their decision makers. They should practically embrace the complexity surrounding decision making and financial and political influences. Spaces for ongoing learning, knowledge construction, visioning and relationship building are key in supporting these shifts.

The city of my dreams is a landscape that thrives with a rich diversity of life forms, of life styles, of life ways. In this dream place all humans and non-humans are all respected in their integrity and equally acknowledged for their unique participation to this large mosaic of ways of being. Living together, close to each other, in a city system, has enable us all to develop multi-faceted conversations, creating unexpected pluricultural ideas and communities, shaping wildly divers open-minded cultures. In this city, streets and parks have melted together. Walking through it is a pleasure for all senses. With its many sounds, languages, tastes, colors, lights, textures, scents, its common space is a gift to the well being of all. Food can be foraged down the corner and everyone can swim in the nearing lake or river or sea. You can drink harvested water from the rain… Crafts and live arts flourish.

The city of my dreams exists in segmented storylines based on lived experiences and identities.  It’s a place where I know no one will yell dyke from their car. My friends will not be attacked walking to their car after dancing the night away with loved ones at the gay bar. It’s a place where it is such a non-issue that I am a butch lesbian married to another woman that even the well-intentioned folks don’t need to tell me about their LGBTQ family. In this city, we take care of our folks experiencing homelessness with wrap-around care. We take down monuments to white supremacy and ensure the diversity of our city is not put at risk because of racist policies. Those are the issues that keep me up at night and the reason why the lens through which I view nature, ecology, and resilience in cities MUST be intersectional and geared toward justice. When I have the luxury of thinking beyond that, I know that the city of my dreams is not static – it’s dynamic! This city inspires enough wonder to challenge the comfort of my assumptions. This city’s landscapes change enough with the seasons and over the years to remind me of impermanence. Every space is infused with function across ecological, social, and economic systems. In this ideal city, I don’t wish for harmony—the friction amongst differing values in community is where the most interesting work is done. Folks who wish for entirely harmonious existence are only searching for a comfort that doesn’t exist.

That’s the big picture. None of what I’ve mentioned above exists without folks willing to have hard conversations. Which, is perhaps why the most important component of the city of my dreams is empathy at its core.

When you think about collaboration what is the first thing that comes to mind? It’s inclusive. It’s equitable. And it’s a meeting of like-minded people with a shared objective. This is the front facing view that folk participating in collaborative efforts want to project to the wider world. 

In reality, collaborative projects can be very different for local authorities. In the past Glasgow has had the academic community present us with proposals and asked us to sign on the dotted line. These statements are then presented back to funding bodies as evidence of collaboration. 

It feels very different to us. It feels like we are being “mined” for our own research and innovation (often described by academics as “grey” research, as in their view it’s not subjected to academic rigour or peer review), which is then repackaged to be validated by the academic world. The repetition of this process, with the view that there is limited value academically in the research that local authority practioners undertake, taints the process of collaboration between academics and practioners and impacts negatively on trust and understanding. 

It’s a breath of fresh air when you encounter a different form of collaboration between academics and local authorities. When we Co-produce research it’s more likely to have joint ownership and understanding. Working together we can innovate in a real world situation and produce sustainable long term solutions to some of the “wicked” issues that local authorities face. It allows us to empower communities to work alongside us and generates trust, empathy and cost effective actions. To take a quote I saw on a Belfast mural “Nothing about us, is for us, without us”.

The city of my dreams is a just city, where all the people have access to clean air, clean water and organically grown food. Where nature thrives in all open and built spaces. Where residents vote on representatives who are concerned to give back a regenerative city, that is positive for the planet to keep providing us the wonders of nature in our common home.

All countries share wisdom acquired from their ancestors and cultures. Regional and local policies and actions orient ecological transformations in all urban landscapes, enhancing ecosystems and the benefits they provide to keep our biosphere’s dynamics.

Ecological knowledge is intertwined in people’s minds since before babies are born, because their parents, families and friends know that their lives are interconnected with the web of biodiversity that sustain our Homo sapiens species.

Our cities are biocentric, biophilic and beautiful. Art is everywhere, inspiring and nurturing our XXI Century civilization.

Nature-based solutions drove contemporary human interventions to restore the damages conventional gray engineering hasmade during the previous 200 years.

Cities became a healthy habitat for us, providing high quality of life and well-being for ALL.

These are ways we can move forward together.

I want to be able to walk up, over, and down buildings coated, literally draped with nature, where ecosystems are intricately woven into the built fabric of the city, where we don’t have to ask who benefits from urban nature, because there is so much, everywhere, that we all have equal access to the clean air, cool breezes, and fresh food that it provides.

But we are not there yet.  To move from the present, to the future we want, we have to put equity first. Greener cities that are more sustainable, more livable, more resilient, and more just, must be also inclusive and address our fundamental social inequities to ensure that all lives improve. Green spaces can’t just be for the wealthy, and when we enrich neighborhoods that have little existing nature, we have to do so while also finding ways to deal with the need for affordable housing, and basic urban services.

I’m excited about the Seeds of a Good Anthropocene that already exist in the present. To have a better future, we first have to imagine it, then we need to make plans that are truly transformative, and get to work to what has to happen in the next ten years, next five years, next week.

This will also require information. What information do we still need to make our decisions truly able to adapt to the constantly changing nature of cities? We need to harness the rapidly emerging and evolving data ecosystem from IoT to social media data to make sense of what our ecosystems, our infrastructure, and our residents are already telling us. But we also have to understand the ethical challenges this data brings with it and do much better to incorporate other ways of knowing, other knowledge systems, while also sharing information better, which is itself another equity challenge. I am hopeful, I am eager to make transformative change, and to work with the knowledge holders on the ground, in our neighborhoods, who already know what they want, and have innovative ideas for hot to get from here, to that more livable, more resilient, and more sustainable future.

Consumed by intense occupations with clients and private projects, architects and planners tend to overlook the immediate environment within which they operate. The city around us is constantly changing, evolving and adapting. Cities, as they grow, are producing several backyards of neglect and exclusion. These backyards are the result of ad-hoc development, lack of a larger urban planning vision and quite simply the market forces that drive today’s development agenda. Most often, these areas of neglect are those that are of no monetary value in terms of real estate potential. Unfortunately, in the case of Indian cities, these are found to be our natural assets- water courses, lakes, mangroves, wetlands, salt pan land and creeks.

 Our governments too have shared the lack of interest in protecting and developing these spaces- and consequently have turned these into some of the dirtiest and most unapproachable areas within our urban environments. With time, these spaces lie in decadence and begin attracting feelings of apathy and disdain. Once considered assets for the growth of communities, these natural assets are now perceived as barriers to development within our cities. Major world cities have, over the years, integrated their natural assets with the goal of creating better urban environments that contribute towards a better quality of life. It is about time that Indian cities take up the similar objectives- in order to create sustainable cities of the future which shift the focus away from pure consumerism towards a more balanced growth with nature.

Four friends met and ended up debating the how the world would end. The ecologist said ‘climate change’, the philosopher ‘nuclear holocaust’, the epidemiologist ‘an airborne virus’ and I said ‘resource scarcity’. At the time I thought oil and phosphorus; resources such as those. But I’ve since realized they are symptoms of something deeper.

The resources we lack so desperately are openness and empathy. They are the most important deficits of our time. Without them we cannot share with other ‘tribes’, whether these are other ethnicities, other generations or other species. Now more than ever, we need collective effort to prevent planetary catastrophe. Instead, we are putting up walls. Through zoning and algorithms, suburbanization and social media have divided us. And when we don’t physically meet those who are unlike us, it becomes harder and harder for us to empathize with them. Right-wing populism has exploited this. But the world of our nightmares can find salvation in the city of our dreams. With courage, we can confront greed and shortsightedness. And we can reject the false narrative that barricades work better than flows. After all, it is the nature of cities to offer contact, camaraderie and common cause. In cities we face difference and, hopefully, see that it is cause for curiosity and celebration. Together we can address the frequent incomprehensible and uncomfortable. And we can better consider the impact of our actions on others in faraway places and times. In the city of our dreams we enrich life instead of extracting from it.

In the city of my dreams, the path of my morning commuteto the Agroecology Cooperativeis halted by a caterpillar, the kind that will transform some day soon, into a yellow swallowtail. Reachingdown, Ibring itwith me, out of the busy footpath, and into the central urban forest.

Walking through an urban forest on this day, means an encounter with slender seven-story buildings, intermingling with ten-story trees, the ground interspersed with foliage and small animal life. Vegetables, fruits, perennial grains, pungent herbs, and a colorful pallet of plants we used to call weeds, but now refer more accurately to as healers of people and the land, all thrive together. Within these mostly wild urban gardens, wildlife also make their home, with rabbits, cats, deer, fox, and the occasional wild boar all paying visits to the forested downtown core.

In the city of my dreams, a group of meditators sit dailyon the steps of the Center for Non-Judgemental Awareness and Connectedness. A pillar of our local government, the center has renderedpolice officers andjudiciary officials unnecessaryfor over a century. Fronting the steps of the center, a family of deer sit lazily in the middle of the main avenue, as the traffic—all on foot and bicycle—simply re-routes around them. A few decades ago, the city banished cars altogether, a part of its ‘slow life’ proclamation, and today nearly everything moves through the re-wilded streets on foot, or some other human powered mechanism. Trains are still used for long-distance travel, though even they have fallen somewhat out of fashion as many humans seem happy to hike or cycle around the country.

In the city of my dreams, though we still have elected officials, few of the humans holding public office are studied politicians. Most come from backgrounds like herbalist, natural baker, brewer, agroecological farmer, or some other pursuit involved directly in building personal relationships with nature.

Emerging from the forest—and releasing thecaterpillar from my handsinto a bush of fennel—I run across thecity’s mayor, who is also the chair of the Council for All Beings.Recently elected by a multi-species vote, the Mayor is thecity’s oldest camphor tree. We are proud to say that she is the first ever camphor to hold the office in a major city.

A very large proportion of the human population now live in urban areas, and the remainder are heavily influenced by the dominance of cities and towns globally. All human communities are now urbanised to some extent. The growth of cities and urban living has resulted in a significant altering of the planet’s ecosystems and their services. We are hearing, on a daily basis, about the problems caused by climate and environmental changes. So, society has devised TECHNICAL solutions and many governments have been promoting BEHAVIOURAL CHANGE solutions, in order to try to mitigate the negative impacts of climate change on our daily lives and to build resilient urban communities. The nature-based solution approach sees NATURE as a technology that can provide solutions to climate pressure in cities, and we see the CO-CREATION approach as a key solution to modify our unsustainable behaviour. Nature-based solutions are inspired by nature, are cost effective, and are capable of providing multiple co-benefits in cities. These co-benefits include environmental services such as clean air and water, pollution control, and carbon sequestration), ecological services (such as increased biodiversity, better connectivity, and habitat restoration), and social services (such as improved health and well-being, cohesive communities, and social innovation). In an ever increasing urbanising world, contact with nature is becoming rare in cities, so by renaturing cities through nature-based solutions many more people will have access to the diverse benefits of contact with nature.

I dream of cities and the people that live there become more and more the engines of innovations, continuously creating new incentives for sustainable landscape management, so that cities become the hope for the planet.

Cities must be more aware of the regions where they are located and take responsibility for a sustainable urbanization. This would entail managing flows and interactions in a more sustainable way, and where not only the cities are developing to become more fair, green and accessible but also the whole region.

We may have come a long way in embracing a more inclusive approach in identifying the challenges ahead, co-designing what should be our priorities, we might also be on the way to collectively generate, co-produce new knowledge on how to create solutions addressing these challenges. In  my mind, where we have failed is in working together to implement these solutions, the co-implementation where we jointly evaluate and monitor for our collective learning of what works and what doesn’t in each local context.

The city of my dreams is never finished.

It is always still becoming, leaving space (and time) for communities to create places that meet their needs, but also—perhaps as importantly—to express themselves. To shape landscape and built environment in ways that reflect local culture, priorities, hopes, and dreams and carry with them the legacies of those that came before. A layered, dense, cosmopolitan strata, the landscape is imbued and activated with diversity and memory. While we continue to evolve toward the future, we hold and honor our ancestors.

These places are a co-creation of residents of all kinds—human and nonhuman—in a complex, collaborative dance. So not only do we leave space for our human neighbors, but we have figured out how to coexist and even thrive with rich, biodiverse assemblages of others. We know the names and stories of our plant and animal kin. We understand their capabilities and their needs and we design our spaces to support their inhabitation as well as ours. We learn from and with them; we recognize our interdependence.

The city of my dreams has opportunities for people to make meaning and live with dignity—whatever that looks like to them. People have jobs that they care about, homes they can afford, transit that is accessible, food that is healthy and nourishing, and many ways to create joy. They have relationships with family, friends, neighbors, and a broad tapestry of civic actors with whom they feel connected.

Through that deep understanding of and lived experience of interconnectedness—with other humans and nonhuman others—we figure out how to forge a new way forward for the planet. Perhaps our inspiration will come from a neighbor down the street, or the photosynthesis of plants, or the intelligence of bees, or the murmuration of starlings—who knows what source might catalyze a new idea? From that idea, we go through the bold, necessary, and drastic steps to decarbonize our economy, transition toward sustainability, and truly address climate change.

But all those actions start with love, reciprocity, and empathy. This also means listening to, acknowledging, and following the wisdom of those who have previously borne the brunt of our society’s failures. We cannot have ecological sustainability without social justice. A city where only a few thrive while others suffer is a nightmare of a dream. Instead, we have constructed a more equitable and just way forward—where we all participate in and benefit from the co-creation of our city, our home.

The Story of Jerusalem’s Railway Park: Getting the City Back on Track, Economically, Environmentally and Socially

Many voices. Greener cities. Better cities.

Sharing local experience is always important. However in the case of the Jerusalem Railway Park, both the process and the outcome have the level of universal relevance that make so many of the themes presented in “The Nature of Cities” essential urban reading.

I refer to themes of the kind that not only have immense impact on a specific local environment, but also fit into the wider context of sustainable urban planning. Indeed, the real challenge of sustainable urban development does not lie in the planning and building of new green neighborhoods, where everything is tidy and organized from square one, but in regenerating abandoned infrastructure in built neighborhoods, taking into account the needs of housing clusters that will be ever denser. Furthermore, the very same new green neighborhoods that claim to be exemplary models of sustainability tend to create new suburbs, requiring additional energy, water, sewage and transport infrastructure. Only too often new suburbs generate a sense of alienation from the pulse of urban life, while playing a role in polluting the city’s inner neighborhoods with the stream of traffic they pour into the city center.

One of the major challenges for modern cities is the need to adapt old infrastructure to modern needs. This is true of many different kinds of infrastructure, such as abandoned quarries, or industrial areas no longer relevant to the city, both of which are examples of the kind of urban challenge created by infrastructure that is no longer needed. Abandoned railway tracks rank high in this category, but in the last decade or so urban planners have risen to the challenge and turned many such abandoned lines into green corridor parks, which enhance, rather than impede urban improvement.

The case of Jerusalem’s Railway Park is particularly interesting, because of the measurable evidence we have of the benefit it is bringing not only to at least a quarter of the city’s residents (more than 200,000 people living in close proximity to the park), but also to visitors to Jerusalem, who see it as a venue for respite and relaxation during their stay. The evidence is measurable economically, environmentally and socially, and this is the triple bottom line result that justifies our investment.

01Over the last twenty years Israel has undertaken a railway revolution, modernizing and expanding the system that was built originally as part of the vision of the Ottoman Empire in the nineteenth century, which established direct rail communication from Alexandria in Egypt to Damascus in Syria. The Turkish North-South grid always included Jerusalem in its itineraries. In the recent years of train revival the railway has become the main mode of transport for more than one and a half million Israelis, taking some of the strain off the main highways, and helping to reduce pollution in our cities.

The railway from Jaffo Port to Jerusalem was the first line to be built by the Turks. The route continued to be used during the British Mandate, and after the establishment of the State of Israel in 1948. In 1993 the Israel Rail Authority stopped using the route, since the journey took twice as long as the inter-city buses, and there had been unpleasant incidents of derailing on the sharp curves of the Jerusalem Hills.

An improved, upgraded route was reinstated in 1998, with a new station being built in Malha, a south-western neighborhood of Jerusalem. This left eight kilometers of abandoned railway track between the new Malha station and the original one.

02While the steam train was running, it cut through the Jerusalem neighborhoods that had developed in the Southern part of the city after the original track had been laid.

The neighborhoods situated alongside the track had always “turned their backs” on the noise, pollution and dirt caused by the train. The train line into Jerusalem drew a clear divide between the communities on either side of the track.

The upgraded electric train from Tel Aviv to Malha completes the journey in 75 minutes, but although from 1998 onwards, the train no longer cut through residential neighborhoods, the communities on either side of the eight kilometers of abandoned track continued to turn their backs on the railway line, which rapidly became an unofficial yet extremely hazardous garbage dump.

At this point, at the close of the 1990’s, civil society organizations, members of the Sustainable Jerusalem Coalition, led by the Society for the Protection of Nature in Israel, began to campaign for a corridor park that would turn the whole area around. The vision of the park was to repair the social and cultural disconnect between the communities on either side of the track, and establish an equitable shared public domain for the seven neighborhoods in the area. These neighborhoods represent most of the diverse communities of Jerusalem, Jewish, Christian, Muslim, old and young, new immigrants alongside old Jerusalem families, rich and poor, religious and secular.

The establishment of a low-cost green corridor park with separate bike and pedestrian paths, including preservation of the original Ottoman rail tracks, has changed the ambience of the entire area.

03The eight-kilometer promenade is used by people of all ages and cultures, practically round the clock. They enjoy the clean air, quiet, social interaction and beauty of the Railway Park. Wheelchairs, baby strollers, joggers and bikers all benefit from an enjoyable and accessible walk/run/skate/ride. The park is also playing an important role in protecting urban biodiversity, since it serves as an ecological corridor linking the chain of inner city parks and gardens to the southern section of the ring of metropolitan parks surrounding the built perimeter of Jerusalem.

04The success of the park is proving to be an incentive for the urban development long needed in the poorer areas adjacent to it.  A couple of the poorer neighborhoods have had densification and urban renewal planned for several decades. However, without a serious incentive no one was interested in moving into the area, and there is no doubt that the Railway Park has rebranded the whole area with its message of beauty, quiet, greenery and health.

The greatest economic benefit has turned out to be one that was not anticipated when the residents first began to campaign to turn the eight kilometers of abandoned railway track into a green corridor park. Those eight kilometers start, or end at the original train station, built by the Turks in the middle of the nineteenth century.

05After the train from Tel Aviv was stopped in 1993, the station, a classic nineteenth century structure, of historic and architectural value, fell into neglect. The place was burgled, vandalized, burnt and more. However, as the plan for the park developed and began to be implemented, Jerusalem businessmen realized the opportunity offered by what has come to be known as “The First Station”. The station houses a large variety of eateries and coffee shops, displays art exhibitions, boasts a small visitors’ center which tells the story of the place, and regularly hosts cultural events. It offers for hire all kinds of bikes and scooters, for use on the track of the railway park and beyond.

06I am aware that Jerusalem is not the only city to have turned an inner city abandoned track into a vibrant corridor park. The New York Highline Park is a famous example, Baltimore has several urban nature trails based on old railway lines, and Philadelphia is moving ahead with its own railway park. However, I am sure that there are hundreds, if not thousands of such neglected urban corridors awaiting green redemption around the world, and perhaps the success of the Jerusalem Railway Park, which has impacted the entire city, while improving the lives of more than a quarter of Jerusalem’s residents, will encourage more urban planners and decision-makers to follow this example.

I owe special thanks to Arch. Yair Avigdor, who headed the planning team of the Railway Park, for his photos. The entire project was led by the Jerusalem Development Authority, and the eight kilometers of the Railway Park constitute the urban section of a forty-three kilometer bike trail loop encompassing the Metropolitan Parks to the West of Jerusalem.

On The Nature of Cities

The Strategy of Sanderlings and the Tactics of Terrapins: What Was Hurricane Sandy Trying to Tell New York City?

Many voices. Greener cities. Better cities.

Like an ancient prophet, armed with forebodings of doom and destruction, Hurricane Sandy bore down on New York City in the early hours of 30 October, 2012.  An extra-tropical cyclone, a thousand miles wide and armed with hurricane strength winds, Sandy was only eight days old.  A fitful infant terrible, Sandy had already visited havoc across Jamaica, Cuba, and the Bahamas; had been a tropical depression, a hurricane, a tropical storm, and a hurricane again; and might have spun without further harm into the north Atlantic Ocean, had not another, weaker storm from the Pacific coincidently crossed the continent on an intersecting trajectory.  Sandy abruptly turned west and made landfall over a spring tide, exaggerated by the fateful alignment of Earth, sun and moon.  The resulting winds and waves took the lives of 79 people in New York and New Jersey and caused an estimated $60 billion in damage, the second most expensive natural disaster in US history.  (Hurricane Katrina in 2005 is first.)  For the millions who lived, routines were disrupted by loss of power, then loss of fuel.  Business ground to a halt.  Lower Manhattan was dark for days.  Hospitals were evacuated, subways flooded, parks emptied, schools shuttered.  Only the salt marshes, a light green, grassy fringe along protected shores, seemed unmoved by the storm.

A prophecy is a message, a communication from beyond the ordinary ken of human beings.  Prophets come to describe what is and to foretell things to come if we refuse to mend our ways.  What was the prophet Sandy trying to tell us about the nature of cities?  What was Sandy’s message about the nature of New York?

In the days immediately following the hurricane, it was hard to know.  The loss was too near, and the damage too extensive for anyone to address anything but the direct perils and mourn the losses just experienced.  But now some time has passed.  Some sixty days and nights later, and with the perspective of a new year just begun, we are given a new opportunity to re-assess what we have learned.

Sandy teaches us that it is not enough to be intelligent, we must also be wise.  Wisdom is more than intelligence.  Where intelligence aims to know facts about the world, wisdom is the use of that knowledge to achieve what is valuable; that is, to choose just and generous ends and to act with courage and deliberation to advance toward them.  An intelligent person knows what to do; a wise person does it.  In the twenty-first century, we have much knowledge, but often seem to lack the wisdom to apply what we know.  Prophets appear to give us the opportunity to change.

And what do we know when it comes to cities and storms?  In New York and New Jersey, it is fairly clear what nature intends as a defense against bad weather from the sea: barrier beaches and dunes block the coasts and behind them salt marshes absorb the surge.

Once the force of the waves is spent, salt marshes slow and hold rising waters.  Photo: Eric Sanderson.

Barrier beaches are long, thin, low islands that form parallel to the shore along wave-dominated coasts; they are shields of sand.  Clearly evident on satellite imagery of the south side of Long Island and along the Jersey shore, barrier beaches continue in a long line south to the Carolinas and Georgia warding the eastern edge of North America.  In New York City, Coney Island in Brooklyn, Far Rockaway in Queens, the South Shore of Staten Island, and the FDR Drive at East Houston Street there are ancient barrier beaches, which old maps show were once surmounted with dunes, in some places thirty feet high, bulwarks held down by grass.

As this detail from an 1844 US Coast Survey chart shows, Coney Island is a barrier island that was once covered with dunes. Extensive salt marshes, shown with the parallel stippling, fill the area behind the beach protecting the old village of Gravesend.  Credit: Library of Congress.

Beaches and dunes form through the movement of sand, lifted out of the ocean, and deposited on-shore by wind and water.  They are unstable but not uncertain; guardians that never collect a day’s pay nor require maintenance except leaving them alone to do their job.  Hurricanes and Nor’easter storms infrequently but dramatically rearrange the details of the geography of these protectors by rearranging beaches, shifting dunes, and forcing open or closing shut tidal inlets, leading to the shallow basins behind.  March 4, 1931; September 21, 1938; September 14, 1944; March 6, 1962; October 30, 1991; December 11, 1992, all mark earlier prophetic visits in advance of Sandy.  In between times, the everyday inhabitants of the shore, sanderlings, dunlins, sandpipers, and killdeer birds, play along the tidal margin, coming and going with each wave, eyes and ears attuned to the atmosphere, ready to fly to safety when poor weather threatens.

Behind the beaches once stood, and still occasionally do stand, extensive salt marshes inhabiting shallow bays and inlet waters.  Jamaica Bay, Coney Island Creek, Great Kills on Staten Island – not to mention Flushing Meadows, Newtown Creek, and the southern Bronx River, elsewhere in New York – were all once great territories of salt marsh and seagrass, the second line of defense against great storms.  Salt marshes, or salt meadows as the old-timers knew them, are peculiar, grassy ecosystems that form in the inter-tidal zone; dry on the low tide, flooded on the high tide, salt marsh plants and animals make a virtue of existence on the edge.  Most can’t live there.  Plants can be drowned like we can, needing fresh air to breathe, and salt desiccates all, so the plants and animals that manage to survive there have special adaptations, not only to flooding, but flooding by salt water.  Spartina swards, for example, have special structures to carry oxygen from leaves above water into submerged roots, and mechanisms to extrude salt out of leaves, so that running a finger along the blade returns a harvest of briny crystals.  The diamondback terrapin, a local coastal denizen, actually cries salty tears to maintain its aqueous homeostasis.  Adapt to stay, turtles tell, climbing above flooded burrows to catch falling rainwater out of a storm.

Given some perspective on time and landscape then, it may come as no surprise that the first places to flood in hurricanes are the past and present salt marshes.  Overlays of the old, buried and forgotten, wetlands of the city and the new evacuation zones show a remarkable geographic concordance.  Wetland edges are often filled in coastal cities to make new waterfront property, but because fill is expensive and labor is dear, they are often raised only just enough to raise them above the tides.

Through the Wildlife Conservation Society’s Welikia Project, we are studying the pre-development extent of New York City ecosystems, including wetlands, as shown on this map.  The results are preliminary as the work is on-going.

Overlaying the historical wetlands and evacuation zones shows that low places are still low a century or more after the wetlands were filled in. Subway tunnels, basements, highways, and other structures in old salt marshes may expect to be flooded by new sea level rise.  Credit: Welikia Project,

And what if the tides rise yet further?

Knowing these facts, wisdom suggests we should follow the strategies of sanderlings and the tactics of terrapins as we plan to spend the billions of dollars that will flow back to the city from the larger nation.  Barrier beaches and salt marshes can protect us still, if we give them space, restore them to their former virtues, and enjoy the city behind them.  We should by all means visit and appreciate the beach as long as we are prepared to retreat to havens on higher ground when tempests approach.  And if we must leave some of our structures near the ocean’s swell, then for God’s sake (and our own), let us build only what is adapted to flooding and the motion of dunes and the surge of tides, so that when the next day dawns clear and bright after the storm, we too can return to celebrate the nature of a wise and resilient city on the ocean’s edge.

The Suburban City, Usefully Seen as a Mega-Landscape

Many voices. Greener cities. Better cities.

A review of The Future of the Suburban City: Lessons from Sustaining Phoenix, by Grady Gammage, Jr. 2016. ISBN 1610916239. Island Press, Washington, D.C. 208 pages. Buy the book.

When taken together, recent books, lectures, and exhibitions on design paint a picture that Architecture and Landscape Architecture are two disciplines moving in opposite directions.

Written in an engaging style, Grady Gammage’s “The Future of the Suburban City” is highly informative and dense with useful information.

In an online video, “Practice vs. Projects”, renowned architect Peter Eisenmen laconically muses about how after the 20th century enjoyed an architectural era of concentrated exploration into shared topics such as modernism, post modernism and other idioms, the contemporary architecture of the 21st century is “flailing about” in search of a new pole star towards which to reorient and refocus the profession’s raison d’etre. From technology and materiality to spatial invention and style, issues and topics in architecture are now are as divergent and atomized as are the architects who author and proliferate the work.

However, that isn’t the case with landscape. By contrast, the topics, interests, and focus of Landscape Architecture are converging into a general exploration and examination of the unprecedented challenges of mega-cities and the reciprocal effects of the human condition they organize and shelter. Whether a design work or text is discussing a particular topic about the environment, ecology, or cultural production, the roots of contemporary landscape design and planning generally trace back and/or share that cities—and the ongoing and unresolved project of how to live and build in the 21st century—is a common denominator.

Published in 2016, “The Future of the Suburban City,” written by Grady Gammage Jr, focuses on the suburban city as a new kind of mega-landscape. Modest in size, the book’s paperback presentation conceals a work that is a highly informative reading, dense with useful information on the topic. Moreover, while the view of the Phoenix-based author provides insight into his home city, readers will very likely pick up that the book is also a template and outline for how to understand and analyze the unique problems of most any suburban city. The presentation and logical sequence of topics about Phoenix could easily be applied to other suburban cities such as Atlanta, San Bernardino, Las Vegas, Dallas, and Houston.

A particularly engaging quality of the book is Gammage’s use of wit and surprise to deliver unexpected information that dispels myths and misunderstandings about the sustainability of suburban cities through statistical and factual characteristics of Phoenix. In a clever and approachable Prologue, Gammage personally riffs on his hometown and recounts the experience of “Getting through a haboob.” When these apocalyptic-looking weather features—which, he sardonically remarks, “were once simply called ‘dust storms,’”—appear, the media and Weather Channel cover them with great drama. In the end, he says, “the biggest consequence was that my pool got really, really dirty.”

Gammage notes that affluence is a substantial driver of the suburban pattern, that the vast majority of American society lives in suburbia, and that Phoenix is actually quite resilient because it doesn’t rely on rainfall—its water sources are conveyed to the city from great distance. These examples may surprise and reshape a reader’s perceptions of Phoenix and other suburban cities.

The book proceeds in seven chapters that are logically sequential, moving from background information on suburban form to challenges of dealing with aridity and ways for suburban cities to enhance their resiliency—and their survival.

In each chapter, Gammage employs a consistent approach: providing clear and simple definitions for the chapter topic, a general and historical grounding on the topic(s), and explaining how Phoenix specifically demonstrates benefits and liabilities of suburban cities. The structural repetition of this organizational pattern makes the book highly accessible and genuinely entertaining.

What Gammage has managed to deliver is an exceptionally useful and thorough book that is just as much a resource to planning professionals as it might also be to non-professional enthusiasts for sustainability. Woven throughout the well-crafted writing are anecdotes that enrich the content. In Chapter Two, for example, Gammage describes how “the last time one state brandished arms against another was when in 1934,” when 102 members of the Arizona National Guard were sent by ferryboat to dislodge four one-inch-thick cables that California had installed to start the construction of a new aqueduct. “The whole affair,” Gammage notes, “was written up in the Los Angeles Times as the hilarious misadventure of the Arizona Navy.”

The simplicity and craft of the writing makes “The Future of the Suburban City” a read that is both specific and general on the topic.

Planning professionals and sustainability enthusiasts who may not have a related educational background will find this book well worth their time. Considering how “home” is a complex and existential condition for everyone, Gammage sustains a neutral and objective tone about what is good, or even admirable, about Phoenix and also the things his city could do better. One could imagine how each suburban city in the United States could produce its story and analyses using Gammage’s book as an armature.

Grady Gammage’s book cuts through the vast amount of information that is currently available on sustainability and mega-cities. As an educator, urban planner, and landscape architect, I highly recommend it.

The Sustainability Challenge of Feeding Cities

Many voices. Greener cities. Better cities.

Until urban planners begin to internalize and address the organization of city food systems, we cannot talk about a complete urban sustainability.
The food system is not as evident as other aspects of urban development. However, it involves many aspects of cities, such as mobility and transportation, commerce, land use, waste management, and, of course, food security.

The food system refers to processes that begin with agricultural production and continues with the processing, packaging and transport that is the result of food industrialization. This industrialization started with the improvements to agricultural production during the 20th century, the so-called “green revolution”. They led to an increase in crop yields and reduction in manpower, which has resulted in the massive abandonment of the countryside and fueled in part the migration to the cities.

The industrialization of agriculture also began the process of territorial segregation between food-growing areas and urban settlements, along with a high consumption of fossil fuels, from the manufacture of fertilizers and pesticides to all phases of production: planting, irrigation, harvesting, distribution and packing. This food production system, not only supplies food for city dwellers, but also contributes to several environmental impacts, including climate change. Thus, everyday eating habits have strong relationships to environment degradation.

On the other hand, the world urban population has been growing during the last century, and since 2008, for the first time in history of humanity, more than a half the world’s population lives in cities. Basically, almost all of the coming decades’ population growth will be urban, and if the current tendency toward the growth of cities continues, 70-80 percent of global population is expected to live in world’s cities by 2050, we get an idea of how important one of the urban challenges is: how to feed this growing urban growing population with the least environmental impact.

Urban food environmental impact

Something as mundane as nutritional habits may have a relationship to environment degradation. What we choose to eat is responsible for more or less impact in two fundamental ways. First, food production and transportation depends on fossil fuels. The second depends on how many animal products are consumed. These food factors have diverse environmental impacts, but also, in the case of the industrial food system, has had regional (territorial)consequences in how urban space is organized, due to segregation of food growing areas from urban settlements. This functional specialization, first at a territorial level, and later at a global level, sustained by increased reliance on fossil fuel has compounded the environmental impacts of the urban food system, such as climate change, but there are also other environmental impacts.

Urban food systems, are responsible for large environmental impacts, involving erosion, deforestation, water and soil pollution, etc. But this essay is focused fundamentally on the environmental impacts from a point of view of the resource consumption needed to feed cities—energy, water and land; and consequences like climate change, and deforestation.

Climate change

The conventional urban model, from an urban ecology point of view is unproductive; It doesn’t generate any resources needed to function. That is why cities are highly dependent on a global transport network, and consequently are tied to continuous fossil fuels consumption, being always affected by fuel availability and price.

But climate change is only one side of the food impact; food production also has an impact on how much water is consumed, and how much land is deforested.

The energy utilized in the global food system includes the energy used in the production of food-stuffs, the manufacture of fertilizers and pesticides, irrigation and the activities of postproduction—processing, packaging and transport, storage and sales—which involves a higher consumption of fossil fuels, and consequently CO2 emissions, greenhouse emissions responsible for climate change. The food chain reveals the importance of indirect consumption of fossil fuels on food—about 6 lbs/per capita a day (Carpentero, 2005)—related to industrial agriculture,

Usually, the carbon gas from fossil fuel combustion has been the center of attention for climate change prevention strategies, and other sources are forgotten. If the food system is analyzed without fossil fuels, agricultural production causes greenhouse gas emissions, directly and indirectly in different ways: By changing land use, deforesting forest areas and transforming them into agricultural land; and by livestock methane emission.

Nearly three-quarters of deforestation and degradation can be attributed to agriculture, including crop production and cattle. The reason why deforestation is related to climate is that when trees are clear-cut they release the carbon they are storing into the atmosphere, and this contributes to global warming. So climate change mitigation strategies should be doing as much as possible to prevent deforestation caused by agriculture, as well as encouraging energy efficiency and reduced transport.

In the case of methane emissions, according to the United Nations (UN), agriculture is responsible for producing more greenhouse gas emissions annually than all worldwide transportation. In fact a World Watch report states that livestock causes 51 percent of all greenhouses gas emissions. But, how could that be? Methane, the gas emitted by cattle, has a global warming potential about 84-87 times the warming effect of CO2 in twenty years, (according to US Environmental Protection Agency’s  inventory of greenhouse gas emissions). This means that the meat and dairy industries have a huge impact on climate change, and urban diet habits trend toward a higher consumption of meat according to Food and Agriculture Organization of the UN.

On the other hand, the effects of climate change on urban food security are another challenge that can lead to a scarcity of foodstuffs. Water is essential for agricultural production, and climate change is especially altering rain patterns. This has become an urban food vulnerability based on a conventional urban food system, characterized by the spread production territory all over the world. Food has so many chains and distances to travel that makes it more difficult to control.

In climate change mitigation and resilience strategies diverse knowledge of direct and indirect urban emissions are required. But mitigation plans are likely to be centered mostly on urban CO2 emissions by transport and mobility; in the meantime urban food’s CO2 and methane could have a largest effect on climate change.

Water consumption

Urban sustainability means reducing resource consumption, including water. Urban water policies address reducing household and commercial consumption. Urban food demand on water indirectly affects urban water consumption, and it should counts toward the urban water footprint, but it is often forgotten.

The fact is that water is required to produce food. This cannot be changed. But the important aspect to be noticed is that the water requirement to produce meat is huge as compared to the requirement to produce vegetables.

According to Water Footprint Network, to produce 1 pound of vegetables, 38 gallons (322 lts/kg) of water are needed, meanwhile, to produce 1 pound of meat, the demand of water is about 1850 gallons of water (7004 lts/kg), 48 times more water to produce meat than vegetables.

Land occupancy

Urban space for city development, includes not only the physical surface occupied by the city’s administrative limits; but also, all the territory employed to produce the resources the city needs. The agricultural land for human feed, and agricultural land for animal forage to produce human feed, should indirectly be considered a functional part of a city. Agricultural production to feed a city is costly in terms of ecosystem impacts, particularly in terms of deforestation.

The amount of land required for agricultural production is directly related to diet. Increasingly, animals raised for food are been feeding less on pasture and more with grains and fodder crops. Consequently a diet based on a high consumption of meat requires at least three times more agricultural land than vegetarian diet. The impact of this choice is so large that, according to Carpintero, given the actual global population and the land, energy and water demands for meat production, it is not Possible to feed humanity with a high animal protein diet.

Urban land demand related to food production, runs counter to the desire for sustainable control of urban land expansion. However, urban sustainable growth should include both limits on the extension of urban boundaries, and control overexpansion of agricultural land for urban feeding.

Urban agriculture and city sustainability

Food for cities is supplied by an urban agro-alimentary system; the improvement of this system could have a positive impact on urban sustainability. Potential improvements include employing different strategies, such as bringing agricultural production closer to urban areas, and changing urban diet to reduce meat consumption. This means decreasing the city dependence on distant agro-system territories spread all over the world that form a fuel dependent global food network. In its place, a regional food agro-system must be developed, so production, distribution and consumption are not distant from each other. In that food system, urban and peri-urban vegetable agriculture would play a fundamental part. However in order to make this shift in food production, urban planning must change its urban food system, and consequently the basic urban model. In order to achieve urban agricultural development that is neither incidental nor isolated, it should be integrated into urban and territorial planning, and to land use. Doing so would foster relationships, not only between urban agricultural production and the city, but would also foster ecological, social and economic relations.

The benefits of this strategy are enormous, not only reducing greenhouses emissions by minimizing food transport, but also by reducing packaging and refrigeration. This means less urban waste and less energy consumption. Also urban and peri-urban agricultural production would take place on previously disturbed land, reducing deforestation of natural areas. , However, this benefit would be increased only if urban diet also reduces meat consumption. In that sense, the city should develop strong social campaigns to persuade citizens to reduce their meat intake, including meat taxes that are related to its environmental impact (climate change, deforestation and water consumption).

On the other hand, urban food vulnerability to the effects of climate change could be reduced with near agricultural production. Food security and adaptation to climate change have a close mutual relationship. The principle of proximity, bringing food production physically close to consumers, takes on a greater importance as a strategy of adaptation, because food availability may become an issue due to transport limitations when climate conditions are difficult. Also by bypassing the chain of fossil fuel consumption, CO2 emissions are reduced, and the price of urban green vegetables stabilizes as they are no longer dependent on a fluctuating fuel prices. Urban food production could supply vegetables that might otherwise be in short supply because of climate change driven drought conditions at remote agricultural lands. Treated urban wastewater can only irrigate agricultural land if it is close to the water source. So urban agricultural production might guarantee food in those difficult weather conditions. Reliance on urban gray water for agricultural production instead of fresh water irrigation could be considered contribution to closing the water cycle.

One important aspect to consider in terms of land use value, is that urban land must be valued not for its real-state potential, but it must be valued for its food security services. However, urban agriculture should be a worthwhile economic activity that could guarantee a long-term return.

But, is it possible for cities to achieve vegetable self-sufficiency?

With the appropriate urban land use strategies, urban green system changes, urban/peri-urban production policies, and urban and building redesign, surely it is possible. According to research on Barcelona, by employing a variety of strategies the city could achieve 70 percent vegetable production self-sufficiency (Arosemena, 2008) . In Panama City traditionally, agriculture production takes place in peri urban areas, principally rice production. Until 2013 Panama City had the potential to be 86 percent self-sufficient in rice production. It was also estimated to be 12 percent self-sufficient in corn production and 6 percent in beans.  While the example of Panama City is not planned peri-urban agriculture these numbers show how urban agricultural self-sufficiency is a possibility. And also to keep in mind that productive potential can also be reduced by urban development pressure.

Conclusions

Every city that expects to be sustainable must take into account all its environmental externalities, and mitigate them as much as possible by reducing the need to exploit other territories and ecosystems in order to achieve the resources city requires to function.

But urban feeding and its associated environmental consequences are usually forgotten when planning for sustainability. In this task, the evaluation of food system environmental impacts involved the consideration of multiple factors, including urban water consumption, land use and deforestation, and climate change. By understanding and accounting for the environmental externalities associated with remote urban food production, and encouraging more local production through changes in urban planning and policies, and encouraging a change in dietary habits to reduce meat consumption, cities can move toward authentic food sustainability. In doing so, the city gets certain degree of self-sufficiency, and in terms of urban food,  begins to develop urban/peri-urban agriculture and ultimately a new urban food system.

Until urban planners begin to internalize and address the organization of city food systems, we cannot talk about a complete urban sustainability.
