The chair recomposes the gap between time of nature and time of man; it evokes a moment of rest, a pause, a convivial and social function.
Mike Feller, New York
For most New Yorkers, the subject is the gargantuan asphalt and cement deck upon which the urban throng careens. The estuary and the 22,000 acres of natural area is negative space. I want my images to confront and undermine this bias with the wonder, and pleasure that I experienced at the time and place of the photograph.
Andrés Flajszer, Barcelona
From documentalism to fiction, I’m interested in witnessing the codes that are based on elements belonging to our bi-dimensional reality and, at the same time, that try to inhabit the in-between space enclosed by the apparent contradictions that shape and define our Anthropocene world.
Mike Houck, Portland
A bronze beaver, installed to honor a lost husband, stands in a tiny but hard won nature preserve in Portland. Everyone knows it, interacts with it, adorns it as the seasons pass.

Perhaps uncomfortable feelings, inspired by images of destructive consumption, can become part of what connects us, serving as fuel for courageous individual and collective action as citizens of a new kind of global community. This hope continues to motivate my work.
Robin Lasser, Oakland
The theme of a recent ZERO1 Biennial was “make your own world.” I thought, if I am to build my own world, over a river, in the age of climate change, the built environment best be prepared for floods, and take into consideration human needs, as well as the needs of other living creatures in the immediate eco system.
Monika Lawrence, Bemidji
When we think of “nature”, we have rural areas, nature reserves, or national parks in mind rather than cities. Why do we often overlook the nature that indeed exists in cities?
Patrick Lydon, San Jose
Can we meet a tree | as we would another human? | Well, of course | we can
David Maddox, New York
In any collection of images from markets and nature-work in cities there is beauty, and bounty, and color—nature’s gifts in abundance. There is also back-breaking work and risk. These are scenes repeated around the world, from Andean or Amazonian markets to Jaipur to early morning truck unloading at the Union Square Greenmarket in New York City.
Christopher Payne, New York
What if these ruins were embodiments of the future and not just the past? The collapse of New York City and its return to a natural state had already happened on North Brother and I thought I had found a way to connect my pictures to a universal story, one that looks into the future and deals with the conundrum of our living in a natural world that we try to alter, but that always reasserts itself in the end.
Eric Sanderson, New York
What was Henry Hudson thinking the day after he sailed into what would someday be New York harbor?  Now it is all ancient history, but at this moment…We imagine him standing on the deck of the Halve Maen, watching the sun rise over Manhattan Island. Perhaps one of his men discharges a musket, scaring a flock of thousand passenger pigeons into the morning light. The day brims with rising warmth and possibility.
Jonathan Stenvall, Stockholm
Our project aims to  show the wildlife outside our doorstep—not only the large number of species that have adapted to live among us, but also the species that are dependent on the valuable green areas that exist in Stockholm and that are, in some cases, threatened. One of these areas is the lake Råstasjön, at risk from plans to construct high-rise buildings.
Benjamin Swett, New York
In my work as a photographer of New York City’s trees, I have tried to show the trees as living objects around which many human associations may have gathered, and to think about what the places where they grow would be like if they were gone.

In his life and work he has practiced in all of these as, in various moments, a scientist, a climate change researcher, a land steward, an ecological practitioner, composer, a playwright, a musician, an actor, and a theatre director. David's dad told him once that he needed a back up plan, something to "fall back on". So he bought a tuba.

Introduction

Photography, and art in general, can help us see. See in new ways. Indeed, it helps us be better at looking. One of the main themes of The Nature of Cities is the idea of “nature nearby”—that cities are not barren of nature, but rather teem with life, both human and non-human. This nature provides services from storm water management to habitat to beauty. Indeed, cities are ecosystems of nature, people, form, and space. Cities are human habitat, and are better designed and maintained when we appreciate them as such.

Yet many people in cities don’t see that nature around them, though they may sense it as part of the nature, or character of their city. Can we learn to look more thoughtfully, and therefore see more fully the natural vibrancy that is all around us in cities? And also along the way see what vibrancy our cities may be lacking? It is a vibrancy that weaves—or should weave—together nature and people and built form in ways that make cities rich—rich in biodiversity, human society, sustainability, resilience, and livability.

So in the spirit of looking more deeply, more finely in ways that can help us see, this is the first of what I hope will be many roundtables on artistic and creative expression on the nature of cities. As is TNOC’s way, the 14 represented here take diverse routes to seeing and sensing the city. What details do they find to make the city more vivid?

Joshua Burch

Hi I'm Josh, a 17 year old award winning wildlife photographer from the UK. As part of a young generation of conservationist I see my photography as a way to inspire others to appreciate its beauty and influence a positive awareness towards conservation.

Joshua Burch

I’ve grown up with an interest in nature since I was about 5, when I spent most of my time collecting all manner of bugs and creatures—generally, anything with more than two legs. My parents bought me my first camera at the age of 10 in the hope that it would reduce the number of escapees in our home!

Rather than grow out of it, my passion for the natural world has grown and now, as part of a young generation of conservationists, I see my photography as a way to inspire others to appreciate its beauty and influence a positive awareness towards conservation by actively supporting and contributing to initiatives like “A Focus On Nature“, a network for young conservationists.

I’m really keen to encourage and develop a network of young nature photographers and would love to connect with people, so please feel free to get in touch. I’m more than happy to share my experience and offer advice (I’m still learning as well), or simply to connect with anyone who shares my interest and passion.

Mike Feller

about the writer
Mike Feller

Mike Feller is an ecological consultant and nature photographer. He worked at NYC Parks for 31 years, where he was Chief Naturalist from 1987 until 2014.

Mike Feller

During the winter of 1985, I mapped archaeological features in the Bronx. One morning, as I stood in deep snow in the forest, I heard rustling behind me. Six feet away, a red-tailed hawk was struggling to subdue a squirrel. For the next half hour I watched the hawk gain control, eviscerate, and begin to eat its prey. I was close enough to see vapor waft from the squirrel’s body and to whiff bile. As the hawk flew away to finish her meal I resolved to buy a camera and begin to record my field experiences.

As a naturalist, photography serves me three ways. First, it allows me to create objective visual documents, record conditions, establish temporal baselines, and inventory specimens better left uncollected. Second, it satisfies my empirical need to record experiences and the aesthetic dimensions of places. It is also a powerful tool for creating experiences through storytelling, slide shows, and exhibits that reveal relationships and meaning to inspire interest, wonder, and sense of place. Third, photography is a conservation tool.

I am most invested in this last aspect. I know from my experience as a native New Yorker that for the majority, the iconic built city leaves no room in the imagination that beautiful, worthwhile natural areas exist. For most, the gargantuan asphalt and cement deck upon which the urban throng careens, is the subject. The estuary and the 22,000 acres of natural area is negative space. In New York Culture is figure, Nature is ground.

I want my images to confront and undermine this bias and to inoculate the viewer with the wonder, pleasure, and excitement or serenity that I experienced at the time and place of the photograph. My conservation heroes are John Muir and John Burroughs, Thomas Coale and Albert Bierstadt, William Henry Jackson and Ansel Adams: writers, artists, and photographers in the Romantic tradition who made their audiences feel deeply for their subjects and moved them to political action that resulted in the creation of national parks and state forest preserves.

I have three approaches to photographing nature in New York, each represented here.

• I shoot landscapes with a 4×5 view camera. It is a deliberate, contemplative process and the subjects I am drawn to are serene places and moments. Some of these shots can take as long as an hour to set up, compose, and wait for light to change or the breeze to diminish. I attempt to exclude people and artifice.

“The Tall Grass Zoo”, a children’s book about exploring small spaces and observing small creatures made a big impression on me as a child. It inspired me to lie where I grew up in the land-filled, weedy edges of Jamaica Bay with chin perched on my hands and watch insects. This was my first experience of the Romantic’s Sublime, described by Joseph Addison as, “…an agreeable kind of horror”. I focus on the small, simultaneously seductive and repulsive, with my macro photography. The diversity of form, color, and life history details of insects provides endless visual interest and descriptions of predator-prey relationships that would curl Edgar Allan Poe’s toes.

• The long telephoto lens is my means of revealing to others the details of the city’s wildlife that I have observed through binoculars. There is nothing quite like viewing for the first time the sapphire eye of a double-crested cormorant or the ruby eye of the black-crowned night heron, radiant jewels hidden in plain sight.

about the writer
Andrés Flajszer

Formed both as architect and photographer, Andrés lives and works in Barcelona. Since 2005 he develops a professional career in photography exploring the relational changes that take place between the built environment and human behavior as they define our contemporary condition.

Andrés Flajszer

Landscape is both object and representation at the same time. Originally a segment of the vast territory, a portion of land becomes a landscape when a multi-layered pack of forces (environmental, political, economical, social, etc.) shapes it in a specific way or direction. All landscapes have visible and invisible sides, always depending on the eye that beholds them. Ever since Nicéphore Nièpce succeeded in capturing his view from a window at Le Gras in 1826 (what is considered to be the first photograph is actually an image of an urban landscape), the world became obsessed with photography as the ultimate tool to capture reality in an accurate and permanent way, an exercise in revealing the truth. Almost two-hundred years have gone by—we’ve moved from daguerreotype to bits and bytes—and so Documentalism gradually gave way to Fiction. We no longer believe in or seek the absolute truth; rather, we try to understand the multiple realities, each real and artificial, that shape and define our Anthropocene world. So, from documentalism to fiction, I’m interested in witnessing the codes that are based on elements belonging to this bi-dimensional reality and, at the same time, that try to inhabit the in-between space enclosed by this apparent contradiction. The result portrays a wide range of elements, from people’s flow to architecture; they are brought to the world of imagery with no will to constitute a proof of reality, but rather to evoke the multiple forces that originated it. One last thing: whenever people are absent from the picture, that which is being portrayed makes them protagonist, because the urban landscape displays the traces of human presence written in our “new” nature.

Much Beloved Beaver

In the early 1980s, we fought a three-year pitched battle to save Heron Pointe Wetland, the only remnant wetland on the West side of the Willamette River near downtown Portland, Oregon. The developer’s consultant argued, as even some natural resource agencies are wont to do, that the less- than-one-acre wetland was so small as to be insignificant from an ecological perspective. Those of us who engaged in efforts to protect the wetland, including a city commissioner’s staffer, a U. S. EPA wetland ecologist, citizen activists, and the Audubon Society of Portland, argued that while the wetland had less ecological value than the nearby 450-acre Ross Island archipelago, it’s true significance lay in the fact that thousands of people would pass by the wetland as they ran, walked or cycled on the Willamette Greenway trail. It would also hold great value, we argued, to the residents of the condominiums that sat adjacent to the trail.

Working with the commissioner of parks and the city’s park bureau, we installed an interpretive sign, hoping to educate passersby about the value of even this small remnant wetland. Thirty years later, an elderly resident of the adjacent Heron Pointe condos installed a two-foot tall bronze beaver to honor her husband, who had succumbed to Alzheimer’s. As the gnawed stumps of several cottonwood trees near the sign attest, her choice was ecologically apropos: beaver actually do use even the small wetland scrap, as do a surprising diversity of avifauna.

I have taken to walking the greenway trail on a five-mile loop twice a week for the past two years, and have been taken with how much the sculpture is loved by passersby. From day one, walkers seem unable to resist giving the beaver a pat on the head, leaving a token of small twigs, a flower, or some other token of their affection. More recently, one greenway frequenter has taken to bestowing seasonally appropriate attire on the beaver, whether it be Easter, Halloween, or the coming of spring. While I always look forward to seeing the feisty Anna’s Hummingbird fiercely guarding his nearby perch on a red-osier dogwood, I am sometimes even more delighted to see what new trinket, beaver-chewed twig, or outfit has been visited on what is a much beloved wetland icon.

Young Naturalist

Eight years ago, while leading a natural history tour of the 160-acre Oaks Bottom Wildlife Refuge, we fell in behind two parents who were, I assume, taking their young naturalist on a walk through the black cottonwood and big-leaf maple riparian forest. I was immediately reminded of Robert Michael Pyle’s book, “The Thunder Tree”, in which he postulated what has become one of my touchstones regarding our decades-long effort to ensure every child has access to nature nearby. Pyle, in a chapter titled “Extinction of Experience,” poses the question, “What’s the extinction of the Condor to a child who has never known a wren?”

Indeed. I have used this image numerous times, and it has even appeared in a prior The Nature of Cities blog by Marianne Krasny. The image of parents taking their happy little camper on a stroll in a wetland that is within a stone’s throw of downtown Portland represents to me the essence of urban nature. This young boy or girl (I’ve never come to a firm conclusion which, but am guessing boy) with the disproportionately large maple leaf has never failed to elicit a strong emotional response during numerous  lectures, whether the audience members are agency ecologists, elected officials, or the general public. Long before Richard Louv launched what is now a national child-nature movement, Pyle started the conversation regarding the importance of nature to children’s emotional and physical well-being, regardless of the setting, but particularly in the urban context.

Condos and Great Blue Herons

I was paddling my kayak around Ross Island in downtown Portland and was blown away by the juxtaposition of the Great Blue Heron colony on the downstream tip of Ross Island with the new condominium towers at South Waterfront, Portland’s newest neighborhood on the west bank of the Willamette. We talk a lot in Portland about integrating the built and natural landscapes, and this comes close to what I have in mind regarding that effort, which we still have a long way to go to truly achieve. While the habitat improvements at South Waterfront have not panned out in the manner we had hoped it would twelve years ago, after two years of planning the Willamette River Greenway, the residents of the condos can now actually observe Bald Eagle picking young herons out of their nests. Not for the squeamish, perhaps, but pretty damn impressive in the heart of downtown Portland.  This heron colony is the remnant of a 55-nest colony farther upstream on Ross Island, after the eagles took over six years ago. I have to say, having testified before our city council in 1979, almost forty years ago, to establish a 350-foot buffer around the heron colony from adjacent sand and gravel extraction, I beheld the eagle intrusion with mixed feelings. Still, we now have both eagles and herons sharing Ross Island, a stone’s throw from our CBD and one of Portland’s newest neighborhoods.

about the writer
Chris Jordan

Chris Jordan’s work explores the collective shadow of contemporary mass culture from a variety of photographic and conceptual perspectives. Edge-walking the lines between beauty and horror, abstraction and representation, the near and the far, the visible and the invisible, Jordan’s images confront the enormous power of humanity’s collective will.

Chris Jordan

These images are drawn from three shows, each depicting scenes from the destructive and consumptive sides of human-nature interactions.

In Katrina’s Wake: Portraits of Loss from an Unnatural Disaster. This series, photographed in New Orleans in November and December of 2005, portrays the cost of Hurricane Katrina on a personal scale. Although the subjects are quite different from those in my earlier Intolerable Beauty series, this project is motivated by the same concerns about our runaway consumerism. There is evidence to suggest that Katrina was not an entirely natural event like an earthquake or tsunami. The 2005 hurricane season’s extraordinary severity can be linked to global warming, which America contributes to in disproportionate measure through our extravagant consumer and industrial practices. Never before have the cumulative effects of our consumerism become so powerfully focused into a visible form, like the sun’s rays narrowed through a magnifying glass. Almost 300,000 Americans lost everything they owned in the Katrina disaster. The question in my mind is whether we are all responsible to some degree.

Intolerable Beauty: Portraits of American Mass Consumption (2003 – 2005). Exploring the USA’s shipping ports and industrial yards, where the accumulated detritus of our consumption is exposed to view like eroded layers in the Grand Canyon, I find evidence of a slow-motion apocalypse in progress. I am appalled by these scenes, and yet also drawn into them. The immense scale of our consumption can appear desolate, macabre, oddly comical and ironic, and even darkly beautiful; for me its consistent feature is a staggering complexity. The pervasiveness of our consumerism holds a seductive kind of mob mentality. Collectively, we are committing a vast and unsustainable act of taking, but we each are anonymous and no one is in charge or accountable for the consequences. I fear that in this process we are doing irreparable harm to our planet and to our individual spirits.

As an American consumer myself, I am in no position to finger wag, but my hope is that these photographs can serve as portals to a kind of cultural self-inquiry. It may not be the most comfortable terrain, but I have heard it said that in risking self-awareness, at least we know that we are awake.

Running the Numbers II: Portraits of global mass culture (2009 – Current). This ongoing series looks at mass phenomena that occur on a global scale. Each image portrays a specific quantity of something: the number of tuna fished from the world’s oceans every fifteen minutes, for example. Finding meaning in global mass phenomena can be difficult because the phenomena themselves are invisible, spread across the earth in millions of separate places. There is no Mount Everest of waste that we can make a pilgrimage to and behold the sobering aggregate of our discarded stuff, seeing and feeling it viscerally with our senses. Instead, we are stuck with trying to comprehend the gravity of these phenomena through the anaesthetizing and emotionally barren language of statistics. Sociologists tell us that the human mind cannot meaningfully grasp numbers higher than a few thousand; yet every day we read of mass phenomena characterized by numbers in the millions, billions, even trillions. Compounding this challenge is our sense of insignificance as individuals in a world of 6.7 billion people. And if we fully open ourselves to the horrors of our times, we also risk becoming overwhelmed, panicked, or emotionally paralyzed. I believe it is worth connecting with these issues and allowing them to matter to us personally, despite the complex mixtures of anger, fear, grief, and rage that this process can entail.

Floating World: A Tent City Campground For Displaced Human and Bird Song
commissioned by The San Jose Public Art Program

In thinking about imaging the urban wild, a public art installation I created for the city of San Jose, in California, USA springs to mind. I was offered an opportunity to create a public work for the ZERO1 Biennial. The theme of the biennial that year was “make your own world.” The site for this installation is located above an urban cement riverbed and under a busy freeway overpass. I thought, if I am to build my own world, over a river, in the age of climate change, the built environment best be prepared for floods, and take into consideration human needs, as well as the needs of other living creatures in the immediate ecosystem. In collaboration with Marguerite Perrret, we created twenty-one miniature disaster relief tents that are cantilevered off the guardrail gracing the bridge that crosses over the Guadalupe River. The tents are built on stilts; the architecture is designed to protect occupants from the possibility of floods. The tent designs are fashioned after temporary relief shelters, and are scaled for birds. Each tent interior contains a speaker or microphone and lantern. The tents are a conflation of human and bird design elements. They provide sanctuary or shelter for bird and human song, water compositions, and interviews with scientists who speak about the Guadalupe Watershed, birds, flooding, and the relationship of floods to climate change.

The site is at once a habitat and transitionary space; it embodies a river, road, and air that supports migration of humans, birds, and fish. This corridor also references a site for potential displacement of animals and people.

The miniature tents provide sanctuary for bird and human song. The sound is a collage of audio interviews with scientists, environmental educators, urban planners, and kids who love the river. These interviews are mixed with water songs written by locals. The water composition is filtered by precipitation data archived during the most severe floods occurring in San Jose over the past half century.

Birds are changing their tune in order to be heard over local anthropogenic noise.   Microphones on site pick up the ambient nose and modify the birdcalls recorded and amplified from speakers in the tent interiors.

The flags refer to the health, ecology and culture of the river. Patterns on the flags are based on mercury molecules, greenhouse gases, native bird species, and macro invertebrates—all indicators of water quality.

Viewing the video and photo documentation of the Floating World sculpture will help to bring these ideas to life. See it here. My work is also part of the show review elsewhere on TNOC.

When we think of “nature”, we have rural areas, nature reserves, or national parks in mind, rather than cities. Why do we often overlook the nature that indeed exists in cities?

More and more wildlife are pulled into new, urban habitats with the decline of natural areas through intensive agriculture, mining, and urban sprawl on the one hand, and enough food and shelter on the other. Moreover, city heat and climate change enable a growing variety of flora and fauna to overwinter in central European latitudes.

Erfurt, the capital of Thuringia, is a city of 200,000 situated in the heart of Germany. It looks back at a history of more than 12 centuries still visible in its medieval inner city; at the same time, it’s a contemporary urban place with modern infrastructure, including a substantial network of public transport and bike trails. More than 50 percent of Erfurt’s population lives in the densely built, relatively small center—a rising tendency as more people seek accessible living environments.

Situated at the transition between the Thuringian basin and the mountain ranges of the Thuringian Forest and the Harz, lots of small streams drain Erfurt’s urban area. Today’s city benefits from several decisions made more than a century ago. A large flood canal (Flutgraben) dug around the old town protects the medieval center from annual flooding. The canal is now a green belt of floodplain forest stretching through the town together with a trail for hikers and bikers. The richness in water bodies provides ideal habitats for insects, frogs, and fish which in turn feed numerous “rural” bird species such as swallows, herons, ducks, or owls. Almost 30 medieval church towers dominate the old town’s silhouette, most with winged inhabitants like falcons or kestrels. Steeples substitute for natural cliffs, including thermal winds for bold flight maneuvers and nesting niches in safe heights. Park landscapes also serve as foraging and hunting areas. Erfurt’s greenspace investments of past centuries are especially important to maintain today, with growing pressures on natural environments elsewhere.

A convergence of needs—human and nonhuman alike—is possible, and in the past 25 years, both Erfurt’s people and its municipal authorities have become more involved in conserving and creating green space. Urban fallows were opened for temporary green space (Zwischennutzung), including an oasis reclaimed from industrial land now used as a community garden. Housing projects densely built at the periphery of the town in socialist times were partially dismantled, opening new spaces, and in the inner city, a planned shopping center had to give way for greenspace with a playground after citizens’ protests. Long-neglected front gardens have been revived, façade greening is getting more popular, newly planted trees give bare streets a fresh look, and competitions for the most beautiful balcony greenings trigger creativity. “Side effects” include a more beautiful city, raised identification with the town, a healthier climate for a city once with quite poor air quality, and more local recreational opportunities. In other words: quality of life.

The inspiration for my photo project came from a course about urban biodiversity my husband Mark gave as a guest lecturer at the University of Applied Sciences Erfurt in 2012. Exploring the urban nature of Erfurt with my camera gave me a whole new perspective on this town where I had been living and working for more than 20 years before I moved to Bemidji, a small town in Minnesota.

unconventional dialogues at the intersection of culture and ecology

In a quest to live ecologically
a man seeks to know nature
in different ways
To know a tree as he knows a good friend
living, growing, sensing
renders betrayal of the tree improbable
Can we meet a tree
as we would another human?
Well, of course
we can

“Centre for Endless Growth”
Building a space for reflection on nature and contemporary culture, Edinburgh, UK

Inspired by dubious proceedings at the World Forum on Natural Capital in Edinburgh, the Center for Endless Growth exhibition offered a public meeting and workspace for catalyzing new ways of thinking about growth, hinting not so quietly that our current methodologies in research and development for economic growth could benefit from direct awareness of ‘real’ growth.

A forest in an office seemed like the appropriate solution. Visitors came in and out during the week, holding meetings and events, and leaving their ideas for a more ecologically just future.

“What is Food: Burger and Cabbage”. Questioning roles in consumption and production, Edinburgh, UK / Berkeley, USA

A living sculpture, What is Food, was created with the help of Vero Alanis and installed in TENT Gallery in Edinburgh, Scotland. It pairs a food which takes very little energy to produce (the cabbage) with one of the most energy-hungry foods (the fast food cheeseburger).

In this role-reversal of sorts, the cabbage slowly feeds on the energy of the decomposing burger during the course of the gallery exhibition.

An archival print of the work was also recently exhibited and acquired by the David Brower Center in Berkeley, California http://www.browercenter.org/exhibitions/reimagining-progress/press

“Disgeotic”. Seeing and feeling the city as a living organism in its own right. International

Disgeotic is a formal, yet almost surreal, photographic survey of urban nature in major cities around the world.

Not simply a matter of pitting growth against decay, these images—the products of walking, lying down, and sitting in cities alone, sometimes for days on end—emote something of the continuous and ever-changing flow of relationships between nature and structure.

This project will extend to include artist-led walking tours this summer in Japan as part of my work for the Robert Callender International Residency for Young Artists.

David Maddox

David loves urban spaces and nature. He loves creativity and collaboration. He loves theatre and music. In his life and work he has practiced in all of these as, in various moments, a scientist, a climate change researcher, a land steward, an ecological practitioner, composer, a playwright, a musician, an actor, and a theatre director. David's dad told him once that he needed a back up plan, something to "fall back on". So he bought a tuba.

David Maddox

Often, and especially in places like Europe and North America—and in media such as The Nature of Cities—we talk of urban nature in the context of emotional benefits: beauty, biophilia, peacefulness. Another context is one of sustenance and work. One form of this work takes the form of agriculture, food, and harvest. In many regions of the world, we are divorced—physically and psychically—from the work of food, the work of nature and its role in human survival. We go to the grocery store, we buy food. Sometimes we go to farmers’ markets. One of the most vivid intersections of the natural and urban world is at markets. When I travel, key destinations for me are markets and areas of natural harvest—places in cities where people still make their living from the land. In any such a collection of images from markets and nature-work in cities there is certainly beauty, and bounty, and color—nature’s gifts in abundance. There is also back-straining work, and the risks of weather and poor harvests and uncertain incomes. Although all these images come from India, they are scenes repeated around the world, from Andean or Amazonian markets to early morning truck unloading at the Union Square Greenmarket in New York City.

North Brother Island

North Brother Island is among the most unexpected of places: an uninhabited island of ruins in New York City that hardly anyone knows; a secret existing in plain sight. Abandoned since 1963, the island was once home to a quarantine hospital and the final residence of Typhoid Mary. Today, it is a wildlife sanctuary closed to the public, but in 2008, I was granted official permission by the New York City Parks Department to take pictures.

I visited North Brother many times between 2008 and 2013, and each time I stepped off the boat I felt as if I had closed my eyes for a few minutes and awakened to find myself in another world, completely alone in the middle of a city. I could not have been happier. In just a few decades, a forest has sprung up where there had once been paved streets, sidewalks, and manicured lawns. If not for the decaying structures, one would never know this place had ever been anything else.

One question that kept nagging me was whether my pictures offered a deeper meaning, beyond their aesthetic appeal and documentary value. Their relationship to New York City and its history was strong, almost overwhelming. Could this small island be viewed in any other context? Did the boundaries of the project extend beyond the geography of the island and the city? Interpreting the ruins as metaphors for the transience of humanity seemed obvious, well-trodden territory. But what if these ruins were embodiments of the future and not just the past? What if all humankind suddenly vanished from the earth? This was the theory proposed by Alan Weisman in his fascinating book, The World Without Us, and it liberated my imagination. The collapse of New York City and its return to a natural state had already happened on North Brother, and Weisman’s words could well have been captions for my photographs. I thought I had found the affirmation I was looking for: a way to connect my pictures to a universal story, one that looks into the future and deals with the conundrum of our living in a natural world that we try to alter, but that always reasserts itself in the end.

Manahatta c. 1609. One way to frame the nature of cities is the nature that was there before the city was. This image shows a reconstruction of Manhattan Island at the moment of European discovery in September 1609. The moment is not important, but this snapshot of nature of that moment is important, because it illustrates why cities end up where they do. Cities are not randomly distributed in nature. Rather they tend to show up in places with good soils for growing food, reliable freshwater supplies, at defensible and well-connected places suitable for trade. Mannahatta, as the Lenape Native Americans knew it; New Amsterdam as the Dutch settlers would call it; and New York City as the English and Americans like to call it, exemplifies all of these geographic exigencies of cities. Manhattan had ok soils, but not exemplary soils. (Much better farmland was found in adjacent Queens and Brooklyn, and across the harbor, in Staten Island.) Manhattan did have over 66 miles of streams and 21 ponds and over 300 springs, including a 70 foot deep freshwater pond, the “Collect Pond”, a 20-minute walk from the tip of the island. That tip of a long, wooded island, where the city was founded in 1626, was surrounded by water on three sides, and hills and the pond behind, making it defensible.  And the harbor waters, deep enough to float ocean-going vessels practically up to the shore, also connected to a flooded, north-south running fjord, the Hudson River, that ran a hundred miles inland.  When the Hudson-Mohawk River systems were connected to the American Midwest by the Eire Canal in 1825, they turned New York City into the greatest mercantile city the world as ever seen.

A Hawks-eye View of the Hudson River, c. 1609. Another advantage of a historical perspective on the nature of cities is that the past sometimes better reveals the nature of cities than the present can. Here, we imagined flying with a kettle of hawks south along the line of the Hudson River. Mannahatta (AKA Manhattan Island) is on the left; and “New Jersey” on the right. The hawk might been a broad-winged hawk or a kestrel or a bald eagle, peering down at the river, where fish such as Atlantic sturgeon, or American shad, or striped bass, were running out to sea. In the distance, a classic “V” of geese travel south.  Mannahatta then, like Manhattan today, is a crossroads of migration.  It is no wonder that the Statue of Liberty stands over New York harbor or Ellis Island, landing point for the ancestors of millions of Americans, are also located here. New York City is also at a climatic crossroads. The day-to-day weather of the city is highly variable, as it receives storms that travel across the continent from the West, weather tracking up the Atlantic seaboard from the south, and storm systems descending overland from the north. And of course the Hudson River estuary, where the river waters and ocean waters mix, is subject to changes in global sea level. Since the time Henry Hudson sailed into these waters, the ocean has come up about nine-tenths of a foot per century, accelerating more in the 20th and early 21st centuries.

Henry Hudson the day after, c. 1609. What was Henry Hudson thinking the day after he sailed into what would someday be New York harbor? Here, we try to imagine that moment. Henry Hudson was possessed with the idea of opening up a northern trade route from Europe to China. He made four voyages during his life. The first two tried the Northeast Passage around Norway and Russia. Both times he was turned back by ice. On his third voyage, he was again instructed to go northeast, but having hit the ice again, he turned his ship around and sailed for America. Alighting on the coast near the English Jamestown colony in 1609, he started on a careful coastal route to the north, exploring the mouth of Delaware Bay, and eventually coming into New York harbor. Seeing the magnificent river, he thought perhaps he had found his way north, through a tidal strait, to riches and fame in the Orient. Instead, the river petered out around modern Albany, New York; Hudson would return disappointed to Europe. On his final journey, in 1610, he made it into the Bay that bears his name, where his crew mutinied, leaving Henry, his son, John, and a few loyal crewmen in a small boat to wait out the winter. They were never heard from again.

We know what happened now, because it is all ancient history, but at this moment, Henry Hudson had no idea what is fate would be. It is easy to imagine he was elated, buoyed by the possibilities of his future. We imagine him standing on the deck of the Halve Maen (“Half Moon”), watching the sun rise over Manhattan Island. Perhaps one of his men discharges a musket, scaring a flock of thousand passenger pigeons into the morning light. The day brims with rising warmth and possibility.

Of course, in that that moment, Hudson missed what was important for the future. His mind was all about tea-cups and trade goods. For us now, in Henry Hudson’s future, we have more teacups and other things from China than we know what do with. What we miss is the nature that Hudson took for granted, that was right in front of him. Nowhere in the world today, no national park, no nature preserve or wilderness, holds the kind of nature that Manhattan had that morning, nature with all its parts and with all its functions, including people as part and parcel of the whole.

We created this image because we feel that every day is full of warmth and possibility. What will we use it for? Will we make the Hudsonian mistake of taking nature for granted? Or we will dedicate ourselves to granting back to nature warmth and possibility in the cities where we live?

Jonathan Stenvall

My project started in the spring 2014; during that spring, I was awarded one of the Hasselblads Foundation’s stipends in nature photography for my project about the urban nature in Stockholm. This project aims to conclude in a book that will show the wildlife outside our doorstep—not only the big amount of species that have adapted to live among us, but also the species that are dependent on the valuable green areas that exists in Stockholm and that are, in some cases, also threatened.

One of these areas is the lake Råstasjön. Råstasjön is a big part of the project mainly because it is threatened by plans to construct high-rise buildings around the lake, which will destroy valuable parts of nature. Råstasjön is a unique lake because of its urban location, just 6 kilometers from central Stockholm and right behind Sweden’s new national  ”Friends arena”. Because of its urban surroundings, Råstasjön is visited by thousands of people every week, from bird watchers to joggers, schools, and kindergartens. All sorts of people travel to Råstasjön to enjoy the wonderful nature that is located in the middle of Stockholm and easy to reach by train, subway, or bus.

Råstasjön also has about 60 nesting bird species. It is one of the best examples of urban nature in Stockholm, with high biodiversity. At the same time, Råstasjön’s urban location opens it up for everybody to see. What makes me worried is that if the construction companies can get permission to build around this lake, one of the most valuable ones in Stockholm, then what stops them from getting building permissions at any other urban lakes in Stockholm and in the rest of Sweden?

With my pictures and this project, I want to show how valuable and how wonderful the nature we get so close to our homes is. I also hope to show that nature with high biodiversity is possible in the middle of the cities, which is why we have to protect it—not only for the large number of animals, birds and plants, but also for our own sake.

Benjamin Swett is a New York-based writer and photographer with a particular interest in combining photographs with text. His books include New York City of Trees (2013), The Hudson Valley: A Cultural Guide (2009), Route 22 (2007), and Great Trees of New York City: A Guide (2000).

Benjamin Swett

New York City contains an estimated 5.2 million trees, which might seem like a lot until you realize that the city also has nearly 8.5 million people. Trees in places such as New York exist in relation to the people and grow, in a sense, at the people’s whim. Much has been written about how trees improve the quality of life in cities by cooling and filtering the air, absorbing excess rainwater, and making neighborhoods more attractive. Less has been said about how they act as storehouses of a city’s past.

In one sense, trees function as living archives, physically storing bits of information about the world around them in their annual growth layers. When studied by dendrochronologists, these layers reveal useful information about the amounts and ratios of sunlight, water, and carbon that reach a tree during a given year. Looked at together, the layers form a pattern that tells a story about the world the tree has experienced during its lifetime. For humans, such records have been valuable in understanding the natural histories of places, and for urban historians in particular, of neighborhoods and cities.

In another way, though, because the lifespans of trees are often so much longer than those of the people who live nearby, and because trees so often assume unusual forms in response to the shapes of the places where they grow, certain trees become focal points for neighborhoods and gather personal associations for the people who live near them or see them every day. It is as if the trees are both part of the urban architecture and separate from it, living things that follow their own organic patterns and change by the seasons and by what goes on around them rather than by the human clock. People develop highly personal emotional connections to these living pieces of architecture and sometimes are not even aware of these connections until the tree is gone. Then suddenly a hole is seen, as if not so much a tree as part of one’s life is missing. If you think of the number of people who live in or regularly pass through different parts of the city, you can begin to picture the number of associations that can develop around a tree that grows there, and the number of people who will be affected if it is gone. This is another kind of history that urban trees carry with them, the history of the many lives that have intersected with them and of the many associations that have gathered around them.

In my work as a photographer of New York City’s trees, I have tried to show the trees as living objects around which such associations may have gathered, and to think about what the places where they grow would be like if they were gone.

A Tree Hitched to the Universe

Art, Science, Action: Green Cities Re-imagined

A wee garden in a windy city

From a leafy suburb in the shadow of Table Mountain, I need not venture far to encounter a myriad of remarkable creatures employing clever survival strategies. Fighting, stalking, feigning, loving, dancing, stealing, and darting, biodiversity spills into and out of my garden. It burrows beneath the lawn, slithers through the leaf litter, creeps up the drain pipes, hunts by the porch lights, and hides in my shoes.

Marvelling at Cape Town’s biodiversity through the lens of an ecologist is akin to gazing into the heavens through the telescope of an astronomer: equally humbling, spellbinding, and seductive. In my modest abode, there are not only remarkable species; there is a vibrant ecological community. It exists not in isolation, but as one tiny island in an archipelago of interconnected public and private greenspace, extending adjacent to the metaphorical mainland of Table Mountain National Park.

With a pair of binoculars, some old field guides, an iSpot account, an eco-literate girlfriend and a little patience, I have identified literally hundreds of species in my own backyard. Simply observing how they interact through the cycle of seasons, I have exacted immense pleasure.

The Scottish naturalist, John Muir, famously wrote:

“When we try to pick out anything by itself, we find it hitched to everything else in the Universe.”

Does this assertion hold true in cities? Can Nature’s long chains of ecological interaction persist in urban landscapes?

Picking out a single tree

Let’s return to my garden, or rather to my neighbour’s garden, where an old Wild Peach tree (Kiggelaria africana) towers over the partitioning wall. The Wild Peach is an indigenous evergreen species unrelated to the well-known fruit-producing Peach tree (Prunus persica). The early European settlers had a habit of naming indigenous South African trees after similar looking species known in Europe e.g. Cape Holly (Ilex mitis), Cape Beech (Rapanea melanophloeos), and African Red Alder (Cunonia capensis). Insofar as the garden is concerned, the Wild Peach tree is a pillar of the ecological community. Its summertime bounty of bell-shaped flowers may have enticed a queen Honeybee (Apis mellifera capensis) to establish her colony in a nearby abandoned car tyre, imparting wafts of sweet caramel into the air. The tree also brings music to the garden: its autumnal orange fruits are relished by the melodic Olive Thrush (Turdus olivaceus), slurring Cape Robin (Cossypha caffra) and chattering Cape White-eye (Zosterops virens).

Honeybees in an old car tyre

The leaves of the Wild Peach are toxic, but gleefully tolerated by one herbivorous species: the Garden Acraea (Acraea horta), a bright orange butterfly whose clutches of 40-150 tiny beige eggs and armies of black spiny caterpillars abound on the leaves all year round (see figure 4). The caterpillars feast voraciously, sometimes stripping the tree almost bare of foliage. By ingesting the Wild Peach’s poison, the caterpillars are themselves rendered toxic and thus unpalatable to would-be predators. However, certain cuckoos, like the Klaas’s Cuckoo (Chrysococcyx klaas), will visit the garden to gorge greedily on the Garden Acraea with seemingly negligible side-effects.

Sunbird

The caterpillars pass through several instars before abseiling off the Wild Peach tree on strands of silk. They disperse in droves, crawling across the flowerbed, lawn and patio, until they reach a suitable pupation site, whereat each caterpillar spins a silk mat before hardening into a chrysalis. The walls of my house are popular—at any given time, hundreds, if not thousands, of these pupae can be found fastened to the paintwork.

Besides the ravenous cuckoos, the Garden Acraea must contend with a range of deadly parasites, including braconid wasps (e.g. Apantales Acraea), ichneumon wasps (e.g. Charops spp.), chalcid wasps (e.g. Brachymeria kassallensis), bristle flies and fungus (see the Box below).

Pupae

The metamorphosis from a caterpillar to a butterfly must be one of the most exquisite processes in the natural world. The small percentage of Garden Acraea to pass unscathed through the gauntlet of predation and parasitism emerge after a fortnight’s pupation as fully-formed adults. They warm themselves in sunshine before setting off, flying clumsily from flower to flower. If they can escape the cuckoos, they will mate and the females will lay eggs on the leaves of the Wild Peach tree, thus recommencing the life-cycle.

A fulcrum in a fragment

It seems that if I were to “pick out” the Wild Peach tree “by itself”, I would lose an awful lot of biodiversity that is currently “hitched” to it; from birds and butterflies to bees and bristle flies. I now look at the old tree with a renewed sense of appreciation. It is a fulcrum in a fragment of greenspace.

There could be many other species playing important roles in the garden’s ecological community. They could be linchpins in long chains of ecological interaction that I barely understand: the family of Cape Dwarf Chameleons (Bradypodion pumilum) which hunt small flying insects in the Blue Felicia Bush (Felicia amelloides); the scores of Egyptian Fruit Bats (Rousettus aegyptiacus) which come to feast on the berries of the Outeniqua Yellowwood (Afrocarpus falcatus); or the pollinating sunbirds which extract nectar from the tubular flowers of the Wild Dagga (Leonotis leonorus).

The example of the Wild Peach tree and the species hitched to it, suggests that:

  1. Indigenous trees can facilitate the establishment of vibrant ecological communities,
  2. Small private gardens can make substantial contributions to native biodiversity, and
  3. Long chains of ecological interaction can persist in urban landscapes.

Through the lens into the mirror

Looking into the mirror through the lens of an ecologist can be as uncomfortable as it is necessary. We might ask, what role do we play in the ecosystem and what is our net impact on Nature? Do we practice what we preach and persuade others to follow suit? Which aspects of our lifestyles need to change?

Contributors to The Nature of Cities have documented various ways to ameliorate our relationship with Nature. Their examples speak of the extraordinary power with which humans can enhance or degrade biodiversity. Clearly, like the Wild Peach tree, we too are part of ecological communities and may constitute links in long chains of ecological interaction. Knowingly or unknowingly, we interact with species both near and far, for better and for worse: the garden irrigation system confounds precipitation patterns and disfavours drought-adapted plants; the electric lights lure countless nocturnal insects to be preyed upon by Marbled Leaf-toed Geckos (Afrogecko porphyreus); the washing machine spews toxic grey water into precious wetlands situated 20 km away; the smooth morning coffee accelerates soil erosion half a continent away.

There is much that we can learn from the example of the old Wild Peach tree. It reminds us that no individual is an island unto itself and that even individuals can render positive and far-reaching ecological benefits. Like the tree, we too are “hitched” to the universe, and any pretension otherwise is delusional and dangerous.

Artists, Vagabonds, and an Accidental Nature Reserve in San Francisco Bay

Art, Science, Action: Green Cities Re-imagined

A review of Refuge in Refuse: Homesteading Art and Culture, an exhibition curated by Robin Lasser, Danielle Siembieda, and Barbara Boissevain at SOMArts, San Francisco, USA. 

Boxer Bob Wanders in the Mansion Ruins by Robin Lasser
“Boxer Bob Wanders in the Mansion Ruins” by Robin Lasser.

For such a far-reaching social and ecological exposition, Refuge in Refuse: Homesteading Art and Culture centers on a surprisingly small piece of man-made land known as the Albany Bulb. A decommissioned construction landfill, the “Bulb”, as it is affectionately known, pokes out into the San Francisco Bay like, well, a bulb…or a mushroom with a long neck (see below).

The residents of the Bulb themselves built their homes on top of decades of industrial garbage.

An unofficial community created by those without community, this thickly layered pile of refuse on top of the bay was home to a salmagundi of unsanctioned homes, gardens, and artworks for decades from the latter half of the 1980’s until their eventual eviction in 2014.

“Albany Bulb and Neck” by Robin Lasser.

To some, it was an example of a kind of unstructured harmony between individuals and a tract of land, both of which had been cast from society. To others, it was a literal hell on earth of anarchy, drugs, and social misfits.

The reality, as this ambitious interdisciplinary exhibition explores–looking at everything from homeless housing to an invasive tree species–is both in between and to each extreme.

3-boxer bob-3d-view

The show highlights works from dozens of professional artists, urban planners, landscape architects, activists, academics, and university students. Robin Lasser, Professor of Art at San Jose State University and the show’s lead artist, says of the exhibition’s curators “we did not so much ‘curate’ the artworks, as connect and gather vantage points from those who had a stake in the Bulb.”

To that end, the exhibition included much collaboration and even several works of art from former Albany Bulb residents, the last of whom were–in a melancholic twist–evicted from the land before the exhibition opening as the city of Albany prepared to convert the former landfill into an “officially sanctioned” public recreational space to be managed by the state of California. This transitional process is now well underway, so the exhibition also acts, in some respects, as an archive.

From practical solutions for the homeless to expressive works of sculpture, the array of pieces in the exhibition is a bit bewildering at first. Yet as one moves through the SOMArts gallery, past a ramshackle home made from trash; pieces of art constructed from landfill gems; striking images of landfill tenants; and historical surveys of the land, nature and human occupation, one begins to put together a sense of what this land was.

A home, a gallery, an accidental nature reserve, the Bulb is conveyed here as a place where people with little traction in the social system in which they lived could try–and in many cases succeeded–to produce an alternative way of living.

4-Mobile_Homeless_Homes_Greg_Kloehn
“Mobile Homeless Homes” by Greg Kloehn, image courtesy of the artist.

On the practical side are pieces such as Greg Kloehn’s “Mobile Homeless Homes.” As resident of Oakland, California, Kloenh writes that he was “impressed by the structures in the homeless encampments…” A sculptor by trade, he decided to attempt making a home from illegally dumped garbage, which he then gave to a homeless couple. His curious experiment has since turned into a small production line, with Kloenh having donated twenty such homes to date. The process by which these homes are built and freely given echoes the fortitude, ingenuity, and at times amazingly supportive community of Albany Bulb residents.

The residents of the Bulb themselves built their homes on top of decades of industrial garbage: telephone poles, wires, lead paint, engines and oil, and, reportedly, the entirety of Richmond City Hall when it was torn down to build a rapid transit line.

Such stories are explored through a short video documentary by Robin Lasser. The documentary gives an honest and explicit picture of the push and tug relationship between the city, the environment, and the residents themselves. Lasser’s compelling visual narrative is complimented here by the thoughtful and poignant commentary of well-known lawyer, artist, and activist Osha Neuman. Neuman, a friend and consultant to many of those at the Bulb, talks of the land from a point of view which intertwines social justice and the arts.

More than a home for social outcasts and artists, Albany Bulb is also “an impressive urban forest that emerged on its own following the closure of the landfill in 1983”, quips another of the installations in the exhibition. This one, titled Albany Bulb Atlas, is a project from the Global Urban Humanities initiative at U.C. Berkeley, part of an ongoing project directed by Susan Moffatt which looks at the intertwining of the lives of people and trees at Albany Bulb.

Drawing comparisons between the environment and those who inhabit it, the work whimsically notes that the tree which thrived here most, the black wood acacia, mirrored the characteristics of the Bulb’s human inhabitants. “In shallow soil or where roots compete, it is a bad actor. Yet in the right place it is well-behaved and beautiful, vigorous and dependable under difficult conditions or of poor soil, wind, and drought.”

The UC Berkeley urban humanities piece is not simply a study or appraisal of landscape transformation, or a cataloging of the natural environment, or even a vision for the future of the land. Rather, it is an effort to build a seamless, almost non-disciplinary review of interactions between people and place.

That sentiment is a good appraisal of what the Refuge in Refuse exhibition does as a whole. It gives an impression that the land as it had been stewarded over the past few decades, with minimal intervention, minimal infrastructure, and yet maximum tenacity and creativity, was brought to a far more natural state than could have been achieved otherwise.

“You see how nature can take over and restore what we have destroyed”, says Neumann of the Bulb’s environment.

Although ‘more natural’ is likely a true statement in this case, the debate over whether this state is better or worse than any other is not necessarily an assertion which this exhibition pushes explicitly. More of a strength than a fault, such broad reach allows freedom for the various parts of the show to independently poke and prod at both sides of the issue.

More than a display of artworks, the Refuge in Refuse exhibition, which moves to UC Berkeley this fall through the Global Urban Humanities initiative, is a place to study and know the story of the Bulb.

Through its diversity of views into how people, nature, and the built environment coalesce, this  substantial show serves as a reference point for alternative socio-ecological possibilities, not just in a landfill on the San Francisco Bay, but any place in the world where social and ecological well being are prone to clash with contemporary agendas.

Story notes: Marianne Krasny and Keith Tidball of Cornell’s Civic Ecology Lab convened a workshop in Annapolis Maryland, at the offices of The National Socio-Environmental Synthesis Center, or SESYNC. (I [David Maddox] facilitated.) The workshop was a gathering of 25 scholars and practitioners, come to talk about civic ecology.

But what is civic ecology? I asked each of the participants to give their short definition. This episode reveals their answers, and there is lots of nuance around some common themes. The work was supported in part by the U.S. Environmental Protection Agency and SESNYC. Special thanks to Jennifer Klein for directing the recordings.

A Tech Touch: Connecting Beaches, Parks, and Big Data

Art, Science, Action: Green Cities Re-imagined

Smart city technology is going beyond data-collecting sensors in streetlights and on garbage containers. It’s expanding to beaches and parks, creating a feedback loop that will allow local Barcelona Metropolitan Area officials to better manage public spaces.

This technology adds a layer of big-data information that, ideally, will help cities fill gaps where their smart city development and environment sustainability plans intersect.

As in many urban areas, the Barcelona Metropolitan Area (AMB) is gradually updating how they engage with residents and looking for innovative, tech-driven ways to deliver greater efficiency and cost effectiveness from their everyday activities.

Many cities globally are already using these kinds of solutions to monitor traffic patterns, improve trash pickup schedules and adjust street lightning as conditions change. The next logical step is to see how citizens use open, public spaces—such as beaches and parks—to figure out how city departments can respond to changing needs, make necessary repairs to park and beach areas, and communicate information to park users and beach goers.

The technology leap 

AMB is heading in this solutions-driven direction thanks to a deal with IBM.

A few months ago, AMB and IBM announced an agreement to use the company’s Intelligent Operations Center (IOC) software, cloud computing, and analytics tools to access, use, and respond to real-time information from parks and beaches within its 36-city jurisdiction.

IMG_6094

The scale of the project will potentially impact millions of residents and visitors.  The greater Barcelona metro area accounts for about 43 percent of the approximately 7.5 million person-population of the autonomous region of Catalonia, and generates 51 percent of Catalonia’s GDP, according to the IBM press release and government statistics. Similarly, Barcelona and its surroundings continue to attract an increasing number of international and regional visitors, many of whom will likely find themselves strolling through local parks and nearby green spaces or enjoying the long stretches of the Mediterranean coastline during their stay.

At its core, the software will centralize all the park management information and provide AMB officials with a dashboard view of real-time happenings, scheduled events, and infrastructure needs. At the beach, the technology will be used to assess and organize demand for sports and entertainment usage and will help in monitoring and managing red flag warnings when there are rough ocean conditions or jellyfish, according to the press release.

IMG_6088

Here are a few other examples of how this centralization will work. As the software is deployed, AMB will be able to inform its 3.2 million residents living in the area about park remodeling projects, special event closures, and other things people would want to know about. From the citizen side, residents can report issues such as broken park benches with their mobile phones and check on the status of repairs. Eventually, AMB and its participating municipalities will be able to tap into additional areas using other IOC capabilities.

Despite several requests for an in-person interview and email responses to questions about how the technology would be used in today’s real-life scenarios and plans to expand it in the future, AMB officials declined to comment or provide additional details about the project pending municipal elections across Spain at the end of May, an AMB spokesperson said via email.

Generally speaking, IBM’s IOC solutions combine hardware, software services (both in the cloud or hosted onsite), preconfigured models analysis and best practices in urban systems management. They are specifically designed for emergencies and transportation and water management, Elisa Martín Garijo, director of innovation and technology at IBM Spain, told me via email.

In the case of water management—an important environmental concern for many urban regions, including Barcelona—the IOC solution helps cities to more efficiently manage water resources and to improve flood protection measures, Martín Garijo said. She added that some cities using the technology have been able to reduce water leakage within the municipal or regional supply system by up to 20 percent. The Netherlands, for example, launched a program a couple of years ago to optimize its flood control system and the country’s entire water system.

Madrid, too, is improving its environmental services with the help of technology, said Martín Garijo. The city’s recently announced the MiNT program, the largest project in IBM’s environmental services management portfolio, addresses several areas, including irrigation, tree and fountain management.

As these projects show, it’s just a matter of time before we see more smart solutions and big-data tools being applied to urban environmental sustainability projects. With luck, they will allow residents and city governments to make better open-space use decisions based on user-generated data and citizen needs rather than political agendas or budgetary limitations.

On The Nature of Cities

What are “Garden Cities” Without a Garden Culture? How a Cultural Connection with Nature Can Build a Truly Sustainable Future

Art, Science, Action: Green Cities Re-imagined

This marks the fourth year that my partner Suhee Kang and I have been studying, working with, living with, and learning from individuals in East Asia and the U.S. who are at the forefront of the sustainable (agri)culture movement.

During this time, our primary goal has been the making of a documentary film, Final Straw: Food, Earth, Happiness. The film is an international exploration of the ecological mindset and lifestyle of “natural farmers,” most of whom are urban transplants, and some of whom still live or work in an urban context.

1_okitsu_japan_lydon

Much can be learned from these natural farmers. Their mindset and actions agree with our most fundamental ideas of what true sustainability should be, placing human beings within nature, working together with nature as integrated parts in an arrangement where both the land and humans benefit.

Yet this mindset also comes across as idealistic, remote, and, quite frankly, very far away from the reality of our mainstream consciousness.

As we came close to finishing the film, we were understandably concerned that urban audiences wouldn’t be able to connect with such an idea in the space of a 74-minute documentary. So we ran a series of test screenings for urbanites before finishing the film to see where our audience was.

To our delight, urban audiences responded with tremendous enthusiasm and recognition; an overwhelming majority of the test audiences at our rough cut screenings were not only vocal in saying that we should “live in a more connected way with nature and the earth,” but were also largely animated to find out how they could take actions in their own lives.

We are waiting to grow roots

It is a great indication for the urban nature movement that the awareness of our need to connect in some meaningful way with our environment is there within people. Yet it is raw; by all means this impulse requires some delicate and constant cultivation in order to grow into a robust culture of individuals who value nature inherently.

Curiously, these individuals—especially 20- and 30-somethings who are second-generation city dwellers—did not express great concern with justifying the importance of the environment, or with reducing CO2 levels, or with calculating their daily impact on their ecological surroundings.

But what these groups lack in concern for environmental quantification or philosophy, they make up for with ample desire to learn how to connect—that is, they desire to understand their relationship to nature and the earth in some meaningful way which transcends the science, numbers, and traditional philosophical rationale.

In our view, then, the more ways we can give these audiences to ‘experience’ nature in a productive, meaningful, personal way, the more successful our efforts at building socially and ecologically equitable cities will be.

The good news here is twofold. First, there are many ways already being developed to enact a more meaningful, productive connection with nature; second, there is good reason to believe that the small groups of individuals we encountered so far—around 200 people over the course of several such screenings—are reflective of a substantial and growing group of people spread throughout urban cores and suburban tracts around the world. All of these individuals know that there needs to be a tremendous change in the way we live our lives: in our consumption, in the way we produce food and goods, and in the way we treat each other and our planet.

From our conversations with these individuals, it is nearly unanimous for those who have the desire to act but are not acting, that they simply have no idea where to start.

One of our suggestions for them—and for people, cities, and organizations in general—is to start with the garden city. That is, not necessarily a garden city as a structure, but rather a garden city as a cultural mindset.

What do I mean by a garden city cultural mindset? For that, I invite you to follow me on a short personal journey…

Discovering a modern garden city

Growing up in the suburb-laden city of San Jose, California, I remember having an obsession with maps and cities. This obsession drew me one day to a book containing works by Ebenezer Howard and the Garden City concepts that he had so beautifully planned. “They seem so cool!” I thought as a young teenager. “But where are these garden cities and why haven’t I ever seen one?”

It wasn’t until a decade later that I realized the sprawling suburbia I grew up in was more or less the result—or perversion—of the Garden City design ideal: a manifestation of garden cities as the prevailing ‘practical’ culture saw it. This realization was disappointing to say the least.

Again, a bit later on in life, my practice became more focused on the interactions of people and places.

During a year spent living thriftily (often on couches) in European and Asian cities of differing shapes and sizes, I witnessed with impressive clarity how the culture of a people who inhabit a place seemed to impress far more of an effect on the outcomes and uses of that place, than the place’s physical design. In both formal and informal urban design, this is an often seen—and not often enough talked about—misalignment between design and culture.

If our urban sustainability issues are indeed so deeply entrenched in culture, it follows that successful urban nature design—indeed, successful sustainable cities in general—can only be achieved in concert with a deep and sustained cultural awareness of the importance of nature. To do otherwise would be like giving a choir a beautifully orchestrated musical score, and not teaching them how to sing. To be sure, this is how many otherwise brilliant ecologically-minded projects turn out.

The mechanisms to build this awareness, to teach our choir of citizens to sing in harmony, are also something which, with the exception of small pockets of influence (in terms of food, I can think immediately of Alice Water’s Edible Schoolyard project, and Food Corps, as good examples) are mostly absent from our cities.

Getting to the root of the issue, I’d like to take a look at the idea of garden city culture with an appropriate example.

The unlikely garden city

This is ‘Dae-dong’, an old, tightly-packed, lower-income neighborhood in the South Korean city of Daejeon.

3_daedong_lydon

Okay. Admittedly, it doesn’t look like an urban gardener’s heaven. But in this neighborhood, almost no plot of soil—and in many cases no slab of idle asphalt, no matter how tiny—is left without tended plants, whether it be flowers or a few corn stalks.

The neighborhood’s design certainly doesn’t have much love for urban gardens, but the residents overwhelmingly do. As my partner Suhee and I found out during a three-month stay as artists in residence here, love for nature is the deciding factor in Dae-dong.

The scale and seemingly hectic layout of the neighborhood is by no means a help to the would-be gardener, and it is quite the opposite of what most American cities aim for. Dae-dong is built to a supremely human-scale, so much so that even the smallest of Korean cars feels awkward to navigate its widest streets. In fact, most of its streets are pathways, barely wide enough for two persons to pass comfortably.

The layout of the neighborhood forces utility of space.

Yet as Suhee and I strolled through the rolling, twisting maze of alleys to meet and talk with locals during our stay, we noticed that gardens are everywhere here. It’s not just a garden in someone’s pint-sized backyard, it’s a proliferation of earth cultivation everywhere in the neighborhood, even in the smallest piece of soil, or in an old bathtub on top of the concrete of the aforementioned narrow walkways.

I realized that what I had found in Dae-dong was a ‘real’ garden city. That is to say, a thriving garden city culture without a garden city plan; a neighborhood with nearly zero planned space for gardens, yet with hundreds of gardens.

How did it happen?

To be clear about the circumstances, the people who partake in this activity in this neighborhood—I fondly refer to them as garden ‘hacking’ grandmothers—are generally from a generation who can still remember the times when they were starving, when Korea had little political organization, much strife through a forced occupation, war, and generally very rough times. The neighborhood was also a home for refugees during the war, some of whom live here still today.

Dae-dong is a success story, at least to show what possibilities exist in small spaces, to show the resiliency and transformation possible when a certain kind of culture pervades, and to reinforce the idea that greening our neighborhoods need not always require large and expensive physical restructuring of those neighborhoods.

5_daejeon_lydon

However, in the years since this older generation of urban farmers began their work in Dae-dong, South Korea has quickly become a technological and industrial mega-power. The development within the country is almost unprecedented, change occurs at quick pace, and most South Koreans under the age of 40 are more concerned with work, study, or vying for a desk at Hyundai or Samsung than they are about a garden.

The cultural connection to and relevance of the natural environment dissolved in South Korea in the space of a single generation, and when the old residents of Dae-dong are gone, the gardens will likely be gone along with them.

That sounds like a dismal point. You may be left mulling over examples of this in your own community; this is inevitable because it feels as though the same story is repeating itself around the industrialized and industrializing world.

We can easily point to laws, regulations, politics, economics, work habits, and other barriers, yet all of these barriers are created, at their root, by the cultural mindset of a place.

Of course, culture, history, and motivation are quite different between places like Dae-Dong and, for example, the garden-suburb-without-many-gardens where I grew up in the United States. Yet in pointing to culture, we also must admit to ourselves that given its very nature, culture is something that is itself cultivated, always growing, always changing.

6_hand_planting_lydon

If a culture of nature-connectedness could be removed from South Korea in a generation, so it could be built again in another.

We must know it in ourselves then, despite the view we have from the culture that we live within here and now—wherever here and now is for us—that the creation of a culture which lives in relative harmony with the natural environment is something which can be cultivated within humanity, first on a local scale, as some are currently experiencing, and, in time, on a global scale, as well.

Kazuaki Okitsu, one of the farmers we spent a good deal of time with during our documentary filming, explained this concept very eloquently:

“Every time we stand in nature
with the plants, the animals, and the vast sky above
we can feel joy in that simple moment
smile if only because we are a part of life on earth
Everyone has these small moments
Everyone gets it, even if we don’t realize it
We understand nature inside ourselves
We just need to cultivate this understanding”

By any measure, or perhaps through lack of the measurable, true sustainable action has much to do with our human capacity to feel, to have compassion, and to experience empathy.

For Suhee and myself, our current tools for approaching this sentiment happen to be in the realm of film and trans-disciplinary community-connected arts projects, but there are endless ways to catalyze beyond this.

The important bit seems to be in facilitating ways to listen to nature, to disconnect from the things which cause destruction of social and ecological life, and to re-connect with our basic human capacity for empathy with the vast, often hidden, living world around us. In his book “The Lost Language of Plants,” author Stephen Buhner writes to this point: “We are by species history and genetic tendency, encoded for the recognition of the aliveness of the world and an emotional bonding with it.” In this statement, Buhner is condensing the concept of “biophilia” as gleaned from biologist E. O. Wilson: a fondness for other life forms.

This is what the natural farmers we worked with have cultivated.

This is what the old grandmothers in Dae-Dong’s unlikely garden plots have cultivated.

And for our part, this is what we must also begin to cultivate in ourselves by reaching for a ‘depth’ of awareness, rethinking our relationship not only ‘to’ but ‘with’ what is around us.

There has been a great receptiveness to such notions so far, one of many signs that a great shift in mentality—and a great shift in culture—is working its way into society.

The ecologically successful culture

In the Final Straw film, we point quite specifically to natural farmers as being examples of ecologically successful microcultures operating within the modern economic landscape, and if we look at the roots of their culture, we see that it is based on all of nature having some kind of sacred or intrinsic value. A recent TNOC roundtable on the sacredness of nature tackles this topic well.

Yet we tend to shy away from concepts such as sacredness and empathy at all costs when we approach the subject in public, and as a result, our language for the importance of nature has become anemic, stunted, and ineffective—an issue in and of itself, of which nature writer Robert MacFarlane recently gave a grand account.

Instead of fostering connection, we insert rationalities, numbers, and balance sheets in between ourselves and the environment, all of which are related to each other, and none of which are so much related to nature in any real way.

These are tools which can certainly be used to facilitate useful conversations, yet reliance on them as the fundamental basis for what we do is perhaps the single greatest inhibition to the growth and sustained influence of ecological thinking and action.

The walls we are used to working with (numbers, balance sheets, etc…) don’t have to disappear, but they must acquire some porousness to them, some breathing holes. With this breathing room, urban nature gains a deeper aspect, economic reasons for destroying natural habitat become unjustifiable, and garden cities have the potential to blossom in any city regardless of its design.

In our experience working with natural farmers and young and eager urban dwellers, as soon as you begin to prick holes and open doors in the walls created by our typical logic-oriented language, a natural appreciation of nature comes quite easily to most human beings. All it takes is an exercise in opening our minds a bit to feel why nature is important for each of us as individuals,

This cultivation can come in many forms and growing food is certainly only one way to carry out such intense and delicate cultivation of individuals, but it’s not the only way, nor is it the only output of value that can be had from a cultural bonding with nature.

A recent TNOC writing by Lindsay Campbell gave a beautiful personal account of “Encountering the Urban Forest,” calling for us to share stories of our personal interactions with trees in order to understand more fully “why we create and maintain urban forests.”

Whether it’s tree planting, urban gardening, artist-led workshops on connecting to nature, talking with Korean grandmother urban garden hackers, or, heck, even talking with trees, we’ve all likely experienced such moments of transformation.

At this point, I would like to pose these open questions to readers:

What actions have you taken where changes occur in how you view your relationship with the environment? How have mindsets changed in these instances? How were these mindsets cultivated and how might they be transferred to other situations?

As I have iterated in the past, the more examples the world has of ways to cultivate sensitivity and connection to nature, the better position we will be in as we continue to understand more deeply what it means to build a sustainable future.

Regardless of how we achieve it, we know that the need and willingness are there within people, and we should believe that a great future is ahead of us, one where sustainable design, planning, nature, and culture coalesce through a re-connecting of people with a deep-rooted awareness of and connection to the earth with which they live.

Chinese Urban Green Areas: Classic Gardens to a Globalized Landscape

Art, Science, Action: Green Cities Re-imagined

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

Classic Chinese private gardens (scholar and imperial gardens) and scenic spots (specially chosen for their scenic natural landscapes) were the dominant type of green space in Chinese cities for almost 2000 years. These gardens were based on the philosophical canons of harmony and beauty (Taoism, Confucianism and Buddhism).

European public elements of green spaces, such as lawns and flowerbeds, were introduced to China by foreign missionaries during the First Opium War (1839-1842). After the establishment of the People’s Republic of China in 1949, some remnants of colonial gardens were transformed into public parks for the local inhabitants. In the 1950s, as a result of the “Learning from the Soviet Union” policy, public, multifunctional parks (similar to the USSR’s concept of Parks of Recreation and Culture) became an integral feature of greenspaces in China.

Since the Chinese Economic Reform in 1978, the use of Western forms for green areas has sped up. Governmental officials had a chance to go abroad and rediscover European Renaissance-Baroque styles, followed by English as well as Modernist styles of landscape architecture. They “fell in love” with manicured lawns and colorful flowerbeds. Finally, when China became a member of the World Trade Organization (WTO), it was included in the process of globalization and globalized landscapes arrived to China.

However, this influx did not take into consideration the different climatic conditions or local cultural traditions. Well-mown lawns together with huge plazas, scattered broad leaved trees and regular flower beds became a symbol of success of the Chinese market economy model. Nobody was embarrassed by the high maintenance costs and low environmental value of such new, placeless urban landscapes.

However, increasing densification, traffic problems, and air pollution forced Chinese landscape architects to start the process of searching for local identity of place and new sustainable models for urban development.

Nowadays, design for urban green areas is done mostly by Chinese private architectural or landscape architectural firms as well as by special planning municipal institutions. In some cases, foreign landscape firms and consultants are also involved in the design and planning stages, especially in large-scale projects such as the Olympic Park in Beijing.

One of the most common types of green areas in Chinese cities is the public park. We were pleasantly surprised to see some principles of Feng shui in the overall design schemes of such parks (orientation, axis etc.). Traditional Chinese garden elements such as rocks, water bodies, classic architecture in Chinese style (pavilions, winding corridors, pagodas and bridges), and paving with stones are actively included in the latest public parks.

However, even these kinds of references to Chinese character are in some cases purely decorative and have lost the spiritual meaningfulness they would have held in Chinese classical gardens. Still, some carving stones mimic the original, very important masterpieces of Chinese calligraphy and provide historic information about the site. We were impressed by the very active use of public parks spaces by people during the weekdays and on holidays.

Green areas inside living neighborhoods (multifamily houses of 4-12 floors). The availability of green areas is varied. From a very limited amount in the living quarters of the 1970-1980s, such spaces grew to a quite reasonable size in the 1990s, and in the 2000s-2010s came to include the greenery of bigger inner yards. In such areas, there is a clear tendency to turning away from productive green areas (no lawns) to more decorative pre-designed areas with standardized lawns, hedges, topiary shrubs, and some ground covers.

However, even in the most recent neighborhoods (established in 2012-2014) people have turned some of these lawns into community gardens. Many urban communities have a specially designated urban agriculture area within their neighborhood. We connected this phenomenon to the agricultural past of people who have left their countryside farms and moved, seeking a better life in the city.

We found a limited number of tree species used for landscape design in Chinese cities. Monocultures—for example, rows of one tree species—are the rule rather than the exception. A “prefabricated” design palette with open lawns, trimmed bushes, and scattered trees landscapes reminded us of classical Western patterns. Famous English Landscape designer Capability Brown would be very pleased seeing such fruitful results of his ideas on Chinese soil. Since the 1990s, China has turned towards using more global plant material.

Suprisingly for us, we were able to identify quite a few Chinese species. These plants, including Koelreuteria paniculata, Gingko biloba, Lagerstroemia indica, Osmanthus fragrans, and Sophora japonica, were also included in the global “pool” of plants for modern urban landscapes and probably date from the late 1990s. They are used in many countries around the world.

We identified one uniquely Chinese type of urban green area—urban nursery plantations for the growing and sale of plant material. Commercial growing of this type fulfills an important ecosystem services in cities. Compared to Western European countries that principally use global nurseries (from a few particular countries specialized in producing plant material), today China has its own local plant nursery market.

Street tree design is also standardized with a tendency to monoculture. Importantly, this particular type of green area plays a very significant role in Chinese cities because of high levels of urban air pollution. The traditional grandeur of formal planning structure in cities such as Xi’an illustrates the key role of the plazas in the front of historic monuments and administrative buildings. Here lawns and annual flowerbeds cover tremendous spaces. The management of such places is the most intensive and is thus incredibly expansive. There are also some surrounding native forests that are used as public parks.

“Gated” community phenomenon

We found the existence of “gated,” highly secured and walled urban communities to be a real surprise considering that before the 1990s, most of the urban green spaces in residential areas (next to homes) were accessible to all people from different areas.  According to Chinese colleagues, this gated community phenomenon related to the change of society towards a more individualistic market economy. Other authors argued that this phenomenon is closely related to the old tradition of people living as one family unit separated from busy street life. We observed especially strict control related to these communities in the most recently-developed, rich neighborhood-villa areas.

In recent years as a result of searching for new sustainable solutions, the green roof concept is also becoming quite fashionable. There are still not many green roofs, and the most dominant form is the intensive green roof located on high-rise buildings in dense downtowns. Such roofs no doubt provide several ecosystem services, but they are expensive to manage and maintain. According to landscape architecture practitioners, this is becoming a restrictive factor for mass use of green roofs in China.

  • Intensive green roof on the top of the building belonging to Real Estate Corporation
  • 7000 m2, structure: roof drainage, sand 30 cm and 80 cm of soil
  • Big area of lawns. Maintenance of lawns is 50% from whole green roof maintenance. 7 yuan per m2 for lawn maintenance. In summer: every 10 days need mowing. Main argument of having lawn: it’s “cooling” effect (compare to hard surfaces) and absence of appropriate ground covers.

One of the main functions of all green areas in Chinese cities is reduction of air pollution.  Today, even a small green area is a very valuable contributor to the physical and spiritual health of Chinese cities.

What we can also conclude from the observation of existing Chinese green areas is that there is a necessity of exchanging good experiences dealing with green areas from Western perspective as well as successful case studies developed by Chinese landscape architects.

We call for creating more hybrid approach emerging positive western and eastern experience.

Complex and Useful, Green Is Infrastructure

Art, Science, Action: Green Cities Re-imagined

A review of Green Infrastructure: A Landscape Approach, by David C. Rouse and Ignacio F. Bunster-Ossa. 2013.  ISBN: 978-1-611900-62-0. Report Number 571. Planning Advisory Service. American Planning Association. 157 pages. Available here

GreenInfrastructureCoverThis PAS Report, in line with the current principles of sustainability, discusses green infrastructure (GI) as the visible expression of natural and human ecosystem processes that work across scales and contexts to provide multiple benefits for people and their environments. Unlike other approaches that envision green infrastructure from the standpoint of social infrastructure (e.g., by building capacity in improved health, job opportunities, community cohesion, etc.), this report addresses it first within the matrix or context of hard infrastructure.

The authors D. C. Rouse and I. F. Bunster-Ossa, two landscape architects and designers, along with contributions from a number of professionals, transmit their holistic views of an integrated landscape, in which ecology, community health and identity, infrastructure, recreation, and public art merge. They also urge professionals involved in these issues to apply multidisciplinary and interdisciplinary approaches in their projects.

The authors renew the holistic call of many anonymous voices from distant civilizations and seminal work from the 19th and 20th centuries to work with Nature and not against it. The need to interconnect natural or “green” systems with the ecosystem services they provide to sustain a functioning community is not new. This concept was applied by many ancient civilizations and held up by important professionals like Penn (1681), the Olmsteds (1870-1900), the Eliots, Manning (1923), McHarg (1969) and A.W.Spirn (1984) and by concepts developed by the present sustainable, ecological and biourbanism. Unfortunately this conception lost strength with the advance of modernity, and because involved professionals have tended to operate independently of one another. Nature devaluation became apparent by the middle of the 20th century, engineered infrastructure eclipsed landscape as the primary driver of urban development. The progress of urbanization and associated infrastructure (roads, utilities, and flood control works), based on hard engineering, had huge and exponential impacts on the landscape, increasing problems instead of bringing solutions.

Rouse and Bunster-Ossa show clearly that GI is a complex system, that spans planning and design disciplines, urban, suburban, and rural contexts and scales. As a term, GI is relatively new to the lexicon of urban planning and landscape design. It appeared in the late 1990s with the intent of elevating the societal value and functions of natural systems to the same importance level as grey infrastructure.

In four chapters the authors present GI as a multifunctional system with components (trees, soil, and constructed infrastructure); organized into a pattern (the landscape); and that performs functions (e.g., stormwater management and the removal of air and water pollutants) that provide benefits. Moreover, they note that GI is part of a hierarchy: it incorporates multiple subsystems (e.g., hydrology, vegetation, and movement) and in turn is a subsystem within a larger system (e.g., region, city, or neighborhood), where it interacts with other systems such as transportation, economy, and governance.

Chapter 2 elaborates on the evolution and basic attributes of GI as a multifunctional system. Chapter 3 addresses its implications for practitioners, with a focus on integrating the work of urban planners and landscape architects. Here the authors bring a set of six unifying principles that can be used by different professions to advance green infrastructure solutions at different scales. In each GI planning practice the principles of multifunctionality, connectivity, habitability, resiliency, identity and return on investment must not be forgotten. Half of the report—Chapter 4—is devoted to eleven American case studies illuminating examples of green infrastructure at the regional scale, in large cities and in smaller communities. Four of these examples discuss parks, greenways, and river corridors. As a bonus, at the end the authors show how the reported case studies embody the six principles laid out earlier in the report.

The Appendix includes a model of an integrated regulatory framework for GI that brings together existing regulations and review processes with new approaches to optimize the interactions between natural and built systems.

The key chapter in this book—Chapter 3—shows how, planners can plan and promote green infrastructure to achieve triple-bottom-line benefits at different scales in different contexts, strikingly presented using the six principles  mentioned above.

Green Infrastructure: A Landscape Approach gives the reader a framework for a sustainable urban and regional future, how can it be implemented, and how  planners and designers can play leading and responsive roles in addressing these issues. Although this report was intended for planners, landscape architects, architects, civil engineers, scientists, and others interested in the spatial structure, functions, and values (environmental, economic, and social) of natural and built landscapes, its simple and enjoyable writing makes it useful for educators, students, citizen groups and conservationists. While all case studies were drawn from communities within the United States, implementing the mentioned principles through green infrastructure initiatives, the variety of contexts and scales make them applicable worldwide.

I strongly recommend this book.

Signals and Snapshots from Semaphore: Musings on Design Guidelines for Urban Fractals

Art, Science, Action: Green Cities Re-imagined

The fractal idea revisited in an attempt to make the concept clearer on a day-to-day, more visceral basis.

semaphore-flag-codes3In my first blog for TNOC I outlined my concept of an ‘urban fractal’ and noted my fascination with the idea that “one might be able to identify patterns in urban systems that could provide a systematic model for developing cities that can always and simultaneously incorporate the essential characteristics of ecologically sustainable urbanism—and that this might be applicable across the spectrum from eco-village to metropolis.” I described an urban fractal as “a network that contains the essential characteristics of the larger network of the city” and that “Each fractal will possess nodes, or centres, and patterns of connectivity that define its structure and organisation, and it will exhibit characteristics of community associated with living processes.”

The ‘essential characteristics’ of ecologically sustainable urbanism most certainly have to do with physical structures and infrastructures that deliver energy and water efficiency, low-to-no waste regimes, clean air and biophysically healthy environments but those are relatively easy to describe. The hard bits are to do with the requirement that each fractal “will exhibit characteristics of community associated with living processes”. It’s hard because communities and living processes are messy, squishy, fluid, tricky to define and full of people who may have their own ideas about how to make their community.

For some time I’ve been wanting to flesh out the idea of urban fractals so that non-specialists might find it more readily understandable and to reinforce the message that this concept is not about making arcane geometric patterns but is about the patterns that manifest in the tapestry of activities and relationships that make up daily life. It’s personal and it’s political.

Urban fractals can be described in terms of acceptable metrics and there are superb analyses of the fractal nature of city form and development (notably by Salat et al  and Batty and Longley) but these invariably discuss the workings of urban life in formalistic terms and, of necessity, resort to jargon. I don’t think most citizens affected by these things would make much sense of the language that professionals employ to discuss them. Too often, planning processes tend away from reification and towards generalities and abstraction and unintended alienation. As both an urban theorist and a real person, I have to admit that this preoccupies me. It preoccupies me because when one’s rhetoric is all about community engagement, and claims that an urban fractal is “a particular type of cultural fractal”, I think it should be accessible to non-specialists and, well, ‘ordinary’ citizens.

A place called Semaphore

This blog is thus an attempt to describe some of the ‘essential characteristics’ of urban fractals in a way that non-specialist might find acceptable and accessible. Based on my own experience of the neighbourhood I’ve lived in for the past three years, it describes parts of the urban fractal idea using the example of a place called Semaphore, in South Australia. It is part photo-essay but the images are not generic, they are specific to a particular place. The same could be done for any neighbourhood as a way to find its fractal threads.

It’s the only town in the world named after a flag-waving communications system . Write a letter addressed simply to Semaphore, and there is no other destination it could be headed to (although whether modern, machine-based postal sorting systems can handle that level of simplicity is a moot point). On a reserve close to the foreshore, Semaphore boasts one of the world’s remaining 60 or so timeballs, still standing, still signalling the need to synchronise our chronometers if we want to find our longitude at sea without GPS.

Until it’s occupied, a town, village or city is not alive. Though its buildings, streets and squares may resonate with the marks of human manufacture it remains as dead as an archaeological dig, its timeball frozen until its empty vessels are filled with people doing all the messy, amazing things that people do to bring urban structures to life. Technology doesn’t make cities. People make cities. All the technology in the world can’t guarantee that things will perform as planned, act as advised or deliver as prescribed. The most advanced aircraft in the world can still be flown into a mountain.

Invisible people

I keep coming back to the realisation that the things that make all the difference, the things that make it all work, don’t show up in plans at all. The blueprints for our cities don’t show people. The professionals involved in the making of our built environment rarely embrace the engagement of the wider community in their planning processes. A lot of architects prefer that their buildings are photographed without people in the shots.

Then there are all the non-human species that help make up the populations of our cities and towns. For the most part they are ignored or regarded as a nuisance or even an enemy. Yes, I know that there are now a lot more design professionals who understand that trees and landscaping deserve more important consideration in their plans than that of merely providing decorative finishes to streetscapes or making generic green space, but I’m not convinced that they are yet in the ascendant—proof to the contrary remains elusive. And there is so much more to non-human occupation of our urban systems than that.

Very few of the human population of a city are ever asked directly about their needs and demands; some take advantage of electoral processes and other ways to influence decision-makers but true plebiscites are rare. The non-human population has no voice or representation at all apart from departments of the environment and sundry under-funded activists. In the absence of Dr Dolittle, who can present a voice for the animals? We have to make do with environmental campaigners and ecologists! The insights and information provided by them needs to be built into design and development programs for our cities and urban systems; think in terms of creating design guidelines for non-human species. No ecocity urban fractal can be complete without them. This blog only begins to hint at the wealth of life that can be found in an unassuming non-ecocity urban fractal—imagine what might be there if we were shaping our neighbourhoods with non-human species given equal weight to us.

Urban fractals are about describing society and its relationship with the environment. Thus they are inevitably about society, culture, politics and, to my own surprise, an acknowledgement of the importance of the people who are the social glue, the people who are cultural catalysts and make us laugh and cry and think, and the much maligned people who stir the pot of politics.

Although it has a strong sense of identity, Semaphore has no autonomy as a political entity. It has been subsumed as a suburb within the City of Port Adelaide Enfield, which is a relatively recent creation that incorporates previously separate council areas and has boundaries which reflect political expediency rather than any sense of place. As Jayne Engle and Nik Luka remind us: “Cities must be seen holistically as containing overlapping and nested neighborhoods.” Neighbourhoods are getting noticed. In Amsterdam, as the city’s compact centre begins to suffer from too much pedestrian traffic (in Australian car-centric cities we can only dream of such a thing) neighbourhoods are being rediscovered as a funky new tourist destinations. This reinforces the idea that the liveliness of cities is not only found in their centres but is part of their whole fabric, manifest in the local communities of neighbourhoods. We’ve known how to make neighbourhoods intuitively for generations, now there’s increasing interest in figuring out what defines and makes a neighbourhood work – and refining the concept of the urban fractal is part of that quest.

Community by numbers?

How do you make community? You can’t really prescribe it, even if products like the Green Star – Communities rating tool developed by the Green Building Council of Australia (GBCA) do an excellent job of melding business and environmental concerns with developer interests in a way that incorporates ‘stakeholder engagement’. Developed “in close collaboration with the market, including all three tiers of government, public and private sector developers, professional services providers, academia, product manufacturers and suppliers and other industry groups” the tool will assuredly help create better developments than might otherwise occur. But a cynic might argue that it is also a product of how curiously neutered political life is at the civic level. It is more about cautious market research than it is about stirring the body politic to new heights of creativity and imagination. It is nicely ordered stuff. But surely, there’s more to real life than that?

Of course, there’s probably an algorithm for it all, but if we are going to rely on any kind of professionally distanced or centralised systems to identify the patterns that inform the algorithms that shape the spaces that house the neighbourhood then we abdicate the imperatives of real community that cause people to talk to each other and explore the myriad possibilities of relationships and actions that are nascent in human society. Community, like a sense of place, is an emergent property of place, circumstance and behaviour and a computer algorithm or rating tool can’t force it into existence. Sub-cultures and communities of interest, be they chambers of commerce or knitting circles, are the grit that can catalyse the production of neighbourhood pearls. Almost any situation involving some level of conflict or difficulty can catalyse the coming together of people that begins community, and so can spontaneous mutual aid, where people cooperate to help each other out because each person benefits in some way from that cooperation. It doesn’t have to be dramatic—“The people who live along the beachside street walk each others dogs, have street parties and collect their neighbours’ bins”—and whether it’s based on self-interest or altruism really doesn’t matter if the result is “We’ve become friends and it makes it easier because everyone looks out for each other” (‘Friends sharing and caring on Arthur St’ p.3 Portside Messenger 25 March 2015 ).

The butcher, the barber, the newsagent, the multi-cultural cafés, the post office, the small, friendly supermarkets, the pub, the pharmacies, the takeaway Chinese joint, the record store that still sells real records, all get a visit on a regular basis; the local service station, the dry cleaner where they remodel clothes, the shoe shop, the optometrist, the physiotherapist, banks, they’re all within easy walking distance; and when the grandchildren come around there’s a playground, the foreshore and the beach. And there’s much more, including churches, schools, dentists, a sweet shop (candy store), pet and garden store, sports grounds, meeting halls, and a community garden. And there’s the legendary RSL (Returned Servicemen’s League) club with cheap curries, live music and a remarkable history.

My neighbour brought me gluten-free muffins morning as I wrote this essay.

This is but a sample of what this neighbourhood can provide. Properly speaking, it is a small town. It has a strong sense of neighbourhood. It’s the sort of place where informal discounts are common, pay tomorrow that’s OK is acceptable, where an expectation of honesty is the default condition. It’s a place where people still seem to trust each other. Even the troubled and damaged citizens living on welfare are treated like the human beings they are, rather than statistics or worse. And all the time there is a strong connection with nature, with the ever-changing sea always visible right down the end of the main street. This place is alive.

How does one design for this to happen? Is it possible?

Someone else’s perception of this urban fractal will be different. There will be shared dots in the picture but connected to form a slightly different pattern. The network of connections is very unlikely be the same for any two Semaphorians but the effect of completeness and general daily experience will be very similar. The range of possible patterns of connection is enormous (I’d love a statistician work out a few figures because quoting numbers always lends an air of authority to this sort of thing – offers anyone?) and this is part of what underpins the perception of rich diversity in a well-used place. And isn’t that true of ecosystems generally? The larger the number of potential destinations, the more potential there is for forming different connections and the richer and more diverse are the observable patterns of behaviour.

The energy of a place like Semaphore comes from people who live and work there and maintain the luxuries and necessities of daily life. The future of a place like Semaphore is determined, in part, by its history, and the course of history is disrupted by people who have dreams or despair of how it might turn out. Ordinary people are rarely ordinary. The Semaphore Workers’ Club was the home of Australia’s strongest Communist Party for many years (and arguably still is). Under the cloak of normalcy, visions stir. Operator of tills, cookers, kitchen sinks and the iconic small business of Sarah’s Sister’s Sustainable Café, Semaphorian Stuart Gifford is one who constantly tears that cloak in response to such stirrings. His drawings of the main street of Semaphore capture something of its diversity and richness of place. The industrial past of Port Adelaide is barely a mile away from Semaphore and is, in some ways, its Siamese twin. Knowing this, Stuart’s drawings of how the Port could transform into an ecological city give more than a few clues as to how Semaphore itself might be trained to develop into the kind of place that might survive this era of catastrophic climate change.

Musings on design guidelines for non-human species

When we design and build environments for particular human purposes—a school perhaps, or a sports facility—we draw on the expertise of people we are familiar with and their requirements in order to write an appropriate brief. The same should apply when we want to build in a way that actively supports, rather than merely tolerates, the needs of other species. The equation is a simple one, the basis of straightforward programming:

IF we want A, THEN we have to have B

IF we want X, THEN we need Y.

There are examples: the specification of particular species of flora to attract particular species of fauna to assist in maintaining biodiversity.

Non-human species do sometimes get consideration in urban planning and management; in this case the City of Port Adelaide Enfield seeks help in trying to protect coastal biodiversity.
Non-human species do sometimes get consideration in urban planning and management; in this case the City of Port Adelaide Enfield seeks help in trying to protect coastal biodiversity.

The hard thing is to find a way to give the other species priority. From their point of view, there is precious little evidence to date that we have done anything other than seek to eradicate or diminish the environment on which they (and ultimately, we) depend. A major cultural shift is needed and it needs to be a shift that does not rely on monetised values of nature for its legitimacy. The market is slippery and unfair and gives very high value to things and processes that create massive environmental (and social) damage. In the perverse world of the market, whether free, controlled or clandestine, the last tigers, elephants—you name it—are being killed because they are so valuable in monetised terms. As the number of dodos diminished, they were valued ever more highly by the market. The cultural shift has to be one that recognises the intrinsic value of other species, not their price in the market place.

Humans adopt their own priorities as they continually change the environment for all species and ecosystems

In the same way that everyone is a distinct individual, every community is unique. It is special within itself, but like every living system on the planet it dies or thrives in response to objective conditions and the level of nurture it can obtain from its environment. As our species has grown ever more invasive and manipulative, so those objective conditions have become increasingly dependent on human behaviour. Unknowingly, or with intent, we play god. That play takes place on the world stage and threatens the viability of the global biosphere, and it takes place in living rooms and backyards whenever we make a choice about how we obtain our energy, water and daily bread. And however individual those choices may seem, we are inescapably social creatures so they are always the result of feelings shared and exchanged, the communing of minds and the dance of personalities.

We know from experience that the world is susceptible to our collective action and that action is grounded in community. It is there, for good or ill, that we make things happen. Semaphore may not be an ecological city, but like many small communities around the world, within its fractal essence, it bears the seeds that could grow one. But for those seeds to grow, there needs to be some effective planning at the neighbourhood scale.

“Neighborhood plans should contain a practical utopian vision for the neighborhood within the larger city, which is translated into medium-term policies and programs but also actions that can be taken on a short-term timeframe”, write Jayne Engle & Nik Luka. This doesn’t really exist in Semaphore. The closest it gets is local government planning and that happens at a level of scale which is outside that of the Semaphore fractal. There have been local business organisations that had some impact on creating events (the Semaphore Street Fair still runs annually) and there have been some attempts by small groups of interested locals to organise events to bring together and catalyse neighbourhood energy, notably through the auspices of Stuart Gifford’s café, but there is no effective organisation that can claim to be undertaking planning for the neighbourhood based on any kind of vision of what Semaphore might become. In this, Semaphore is not unusual, but to gird our loins for the battle with climate change and ecological instability that’s now rising on the horizon like a tsunami, every neighbourhood urban fractal needs to be planning for itself, working out how to turn its social energy into an effective force for positive change so that the patterns that make daily life functional, fun or fulfilling can continue.

Rising seas are an uncomfortable fact and will have to be factored into any serious plans for the future
Rising seas are an uncomfortable fact and will have to be factored into any serious plans for the future

In the long term, to continue this thought experiment further—if Semaphore were to evolve into an ecocity urban fractal it would need to exhibit the characteristics of a fully-featured ecopolis [see my first blog and the box] in order to possess the resilience and autonomy required for surviving climate change and the 7 metres of sea level rise that would transform it into an island.

This is a work-in-progress.

Where Can Civic Ecology Lead? TNOC Podcast Episode 003

Story notes: A conversation about civic ecology between Lance Gunderson, a landscape ecologist from Emory University in Atlanta; Caroline Lewis, of Climate Leadership Engagement Opportunities, or CLEO, in Miami; and Arjen Wals, a professor of social learning and sustainable development at Wageningen University, The Netherlands.

Climate change and other stresses on cities represent great challenges to societies. Some of these challenges are systematic and somehow “knowable”—that is, we know generally what to expect, even if we aren’t sure how to respond. Other threats and stresses are unexpected, even random in the appearance. Things happen that put pressure on our systems, organizations, and communities that we didn’t expect, and didn’t necessarily plan for—freak storms, or economic stress, or the loss of a charismatic leader. Our ability to respond to the unexpected is one aspect to the idea of resilience. Are our communities flexible or brittle in the face of shocks?

This episode of This Is The Nature of Cities discusses these issues and role Civic Ecology plays is maintaining resilient and vibrant communities. What is civic ecology? Think community gardens, or faith groups working in sustainability, river restoration organizations, or friends of parks groups. Such organizations form key and critical elements to the functioning of resilient communities, not just in their direct action, but in their contribution to social cohesion.

Marianne KrasnyGardeningWithKids-GuerrillaGarden-BGN and Keith Tidball convened a group of civic ecology leaders at the National Socio-Environmental Synthesis Center, or SESNYC, to discuss their work. In the green room three of the attendees met to talk about civic ecology organizations and how they are key to resilience.

Green Transport Routes Are Social-Cultural-Ecological Corridors

Art, Science, Action: Green Cities Re-imagined

Since moving from Edinburgh to London, I have greatly missed my bicycle commute along the former’s Union Canal. There are similar routes in London, but they’re unfortunately not on my way to work. I have always sought out such corridors and they have sometimes influenced my destinations. In response to the “Why are you interested in this position?” question in a job interview, I once admitted that getting to work via Montreal’s Lachine Canal was a big draw.

While I’ve long been aware of the positive effects of daily opportunities to get away from traffic and closer to some form of nature, it is only recently that I have given serious thought to the wider significance of green transport corridors in cities. I have written previously about how urban landscapes convey forceful messages concerning the nature of cities and the role of citizens. In that article, I described how certain landscapes can invite citizens to collaborate with nature in ways that make cities more socially and ecologically resilient. The ‘Inviting Landscape’ in question is most typically a neglected space that is transformed into a garden or pocket park—but what about the landscapes we travel through en route to our daily destinations?

Experiencing the city through its transport infrastructure

Paths

In my quest to locate Inviting Landscapes (as part of my PhD research), I journeyed to almost every corner of Manchester. If you’ve ever been there and noticed the elevated motorway running through the city centre, it will come as no surprise that Manchester’s planners have not always considered the needs of pedestrians and cyclists when designing transport infrastructure; there are some terrible roads from a cycling point of view. Fortunately, Manchester also has cycleways and footpaths (and, increasingly, paths shared by cyclists and pedestrians) and I set out to navigate these. As I moved through Manchester’s less visible transport infrastructure, I became increasingly conscious of the significance of transport corridors in defining perceptions of the city. I once spent a childhood holiday on a canal boat and although cars must have crossed bridges over our route, I thought for many years that I had been to places where the streets were water. I sometimes come close to reliving that experience when I arrive in new places via green corridors. It gives me a different sense of my destination and of the city overall.

Transport infrastructure takes up a lot of space in cities. Road networks and car parking cover huge areas of most cities and therefore tend to be key features in the urban landscape that most of us carry around in our heads. Such a grey and monotonous landscape, with little sign of nature or people (other than those encased in cars), constitutes a major part of many people’s daily experience of being outside. Large scale and imposing infrastructure is characterised by obduracy (Hommels, 2005)—that is, it feels like it will be there forever and we mere humans have no capacity to change it.

But moving through a city along a footpath or cycleway, a place of wildflowers and birdsong may reveal itself. One might graze on berries if hungry and enjoy the microclimate of a well-vegetated corridor on a hot day. Such corridors provide health and well-being benefits for people who use them (Tzoulas et al., 2007), and the multi-functional aspect of connective green infrastructure, with its social value in terms of recreation and movement networks, has been recognised in the practice literature (Town and Country Planning Association, 2007). For people who consistently use green corridors, the regular contact with nature also helps to begin to conceive of the city as embedded in nature—as part of an ecosystem, or a social-ecological system, where such green infrastructure is the norm.

Green transport routes provide everyday contact with nature—and more

A key feature of this movement among everyday destinations is that it is not a recreational foray outside the daily lived experience of the city, and accessing it should not require setting aside time and other resources. I was interested to hear mention in a recent TNOC podcast of the potential of linear parks to increase equitable access to nature. I would emphasise that attending to their transport function further enhances this potential and may serve other functions, as well. Here in London, a community leader in Tottenham has pointed out that good cycling infrastructure along the River Lea would increase access to jobs as well as to nature for people who find other forms of private and public transport too costly.

That green transport corridors are part of their users’ daily lives, as well as natural places close to home for the many people who live along them, facilitates the engagement of citizens interested in looking after them. However, more efforts are required to extend the invitation to engage to both users and stewards. The UK is relatively blessed with alternative transport networks because of a tradition of footpaths and protection of rights of way. But in recent years, the same lack of care that has affected other urban landscapes has made green corridors uninviting to many people. If people are fearful or uncomfortable about using these areas, none of the benefits described above will accrue.

Making green transport infrastructure more inviting

Users of green corridors in Manchester spoke to me about some specific problems that seemed likely to inhibit use. They described how sections of canal towpaths and footpaths/cycleways were very isolated with few “escape routes” and uncertainty about possible obstructions around the next bend (often related to inadequate maintenance).

As I moved through these corridors on foot and on bicycle, I noted that the walls and fences and barbed wire separating these pathways from the surrounding neighbourhoods seemed designed to keep bad things in. They conveyed a message that the natural corridors of Manchester were dangerous places from which neighbours needed protection. A key moment occurs when deciding whether to enter the corridor, and inviting and uninviting entrances are an obvious factor.

There are also many examples of places along routes that make it unclear where to go next. One arrives at a dead end or there is a lack of signage—and natural corridors do not appear on the standard online GPS systems that people increasingly use to plan their routes. In other cases, the path is suddenly interrupted by infrastructure hostile to pedestrians and cyclists. It is clear that green and active transport routes are an afterthought, an add-on, rather than a core part of the city’s transport strategy.

Local government should invest in developing and maintaining the natural connective tissue of the city. In the same way that significant investment is made in arterial roads because they are believed to serve everyone and to connect up vital places, so inviting connective green infrastructure should be supported. The canals, footpaths, and cycleways that provide routes for active transport should appear prominently on maps and signage. Whole systems should be indicated when possible, even when portions of them are currently inaccessible, in order to enhance system understanding, and to encourage thinking about connecting up fragmented corridors.

Moving more than people along social-ecological corridors

It is also worth thinking about how people moving around green corridors may be moving more than their own bodies. The October 2014 TNOC Roundtable raised some questions about the capacity of urban green corridors to contribute to habitat connectivity. Can people in these corridors help to enhance this connectivity?

As Andersson (2006, p. 3) points out in relation to maintaining spatial resilience: “There are two aspects of connectivity, the continuity of a certain habitat (structural connectivity) and the possibility for organisms to move within or between patches (functional connectivity).” The important thing is that they find a way to move, and sometimes people can facilitate this. A wildlife conservation manager discussing how increasing urban permeability would help species migrate and therefore survive climate change told me, half jokingly, that with respect to plants, “it might be quicker to just dig them up and move them through!” This comment has stayed with me in recent years as I have watched many citizens involved in transforming urban landscapes physically move plants around.

While most plants are still purchased and driven to private gardens (and have been known to create invasive species problems), there are more and more citizens who are moving plants in an effort to enhance social-ecological systems. They reintroduce indigenous species or create edible landscapes or plant wildflowers that make landscapes more attractive and inviting. The plants are often obtained from other citizens or community organisations engaged in similar efforts at other sites, and are frequently accompanied by the ideas and skills of the fellow citizens that bring them (often by bike and along natural corridors when possible).

It has been suggested that landscape ecology has limited applicability in cities because ecosystem processes have been so disrupted that function no longer follows form (Andersson, Ibid.). However, function perhaps still follows form, but the form is a ‘messy social-ecological system’ (Alessa, Kliskey, & Altaweel, 2009). It includes a variety of people, nature, and places bound together in a complex web of relationships. And people, with their visions of what the city is and can be, are often the ones facilitating system connections. Conventional infrastructure, which has long determined the flows of matter and energy in cities, still dominates, but people with different ideas are simultaneously carrying matter, skills, and inspiration among sites and along corridors in the context of a more collaborative relationship with nature.

The more people feel comfortable and spend time in green (or greenable) spaces and corridors, the more likely they are to use them, to appropriate them, and to look after them. Those who move in these corridors begin to see the landscape of the whole city and our place in it from a different perspective. It allows us to reconceptualise urban systems, to shift away from a focus on large-scale systems—where people and nature are largely invisible—to more human-scale, systems where the importance of what nature is doing and what citizens are experiencing and doing can be seen and supported. Efforts to expand multifunctional green infrastructure should be accompanied by visions for cultural and experienced landscapes that redefine the city.

Unintended Consequences: When Environmental “Goods” Turn Bad

Art, Science, Action: Green Cities Re-imagined

After a hectic start to 2015, I finally managed to slow down the pace. A few days ago, I attempted to catch up on some overdue readings—my way to keep in the loop. Among the many documents piling up on my computer desktop was this short podcast from TNOC: “Closing the Sustainability and Equity Gap: What does it mean to be both a green and just city?” It was the conclusive debate of the 2014 MAS (Municipal Art Society) Summit for New York City, with Toni Griffin and David Maddox as the two debaters.

I was sitting comfortably in my favorite armchair, sipping coffee and listening to this podcast with my headphones on, when all of a sudden I heard: “We have been relatively good at discussing—not enough, but relatively good—at discussing the idea of environmental bads…” The whole idea was that we had not paid sufficient attention to environmental goods. “Green spaces”—especially linear parks—were described as paragons of environmental goods. I started thinking, Wow. Really? This idea stuck in my mind, because it clashed with my own experience. I am not convinced at all that actual urban policies focus mainly on what we could call environmental bads: building eco-districts and designing environmental friendly areas is creating environmental goods; both smart cities and resilient cities—two different and somewhat contradictory approaches—focus on the bright side of sustainability (designing the future) rather than the bad side. Besides, I am also unconvinced that green spaces are inherently “positive”, both from an environmental and social point of view. They may even, on some occasions, generate very negative and unexpected side effects.

The failure of Seine-St-Denis

In one of my more recently published articles —Combining Sustainability and Social Justice in the Paris Metropolitan Region—I showed that creating environmental goods and amenities such as parks “out of the blue” is absolutely not sufficient to enhance urban justice, be it distributive, restorative or interpersonal. Look at Seine-St-Denis near Paris, a case that deserves special attention. At the scale of the Paris metropolitan region, this area has a very poor image due to its industrial heritage and the presence of large social-housing units. It is associated with environmental shortcomings and low quality of life.

Parisians usually avoid this area because they see it as ugly and unsafe, while most of the inhabitants of Seine-St-Denis have the feeling that they live in a bad place, in which they consider themselves abandoned. They’d like to relocate, but they generally lack the financial ability to do so, or they are stuck in this area by their professional activity. So, their sense of belonging to the place they live in, their sense of ownership, and finally their self-esteem, are very low. A book about the industrial heritage of Seine-St-Denis between 1850 and 2000—Dangereux, insalubres et incommodes: paysages industriels en banlieue parisienne (XIXe-XXe siècles)—shows that the prejudice against Seine-St-Denis is strong. But guess what? The deindustrialization of Seine-St-Denis happened forty years ago. Since then, countless major urban regeneration and urban reconfiguration programs were developed, as explained by Sylvie Salles in her article “La reconversion de la Plaine Saint-Denis, le paysage à l’épreuve du territories”. Parks were created in former wastelands and brownfields; linear parks were designed along formal industrial transit roads, railroad tracks, and canals. Eco-districts of social housing were built, connected by hundred kilometers of tram tracks, new subway lines, and soft mobility systems (bikes and pedestrian paths). Better still, cultural amenities such as museums, libraries and theater companies were financed. Attractive heritage sites, such as Basilique de St-Denis—a very important one—or the industrial sites of the 19th century were restored with increased access for everybody. There are also two universities in Seine-St-Denis now.

Very little has been done to cope with the environmental bads, such as polluted soils or traffic noise. A lot of money has been invested to enhance or create environmental goods in Seine-St-Denis, yet nobody wants to live there. It remains a “bad area” and a stigmatizing place, whatever efforts have been made there. It is surely not a coincidence that almost all of the last years’ French urban riots took place in Seine-St-Denis.

The good, the bad, or the ugly: which should we prioritize?

Let’s play the devil’s advocate and consider what happens when urban policies focusing on environmental goods, green amenities, and nice ecosystem services, succeed in creating attractive areas. Is this situation positive for urban equity and urban justice? A first observation: urban injustice in the Paris metropolitan region increased significantly during the last twenty years. Curiously enough, this co-ocurred with the rising of sustainability policies. Was this some sort of accident? Probably not! In his article “Selective public policies: sustainability and neoliberal urban restructuring”, Vincent Béal points out that urban policies changed in the 1990s, as the sustainability issue became a top priority in a context of urban neoliberalization. Policies shifted with the development of a very aggressive urban marketing initiative designed to attract upper classes and the so-called “creative” classes to urban centers. This new orientation—linking together environmental and economic objectives—naturally induced spatial segregation and urban injustice, since poor people lost access to nice natural and living environments because they couldn’t afford to live in such locations anymore. Thus, green policies based on environmental goods may result in dramatic—if not intentional—negative side effects for urban justice.

All things considered, there may be some good sense in coping first with the environmental “bads”, which, by the way, is not such a frequent attitude in real life. In the Paris Metropolitan Region, nearly 70 percent of the socially-deprived communes (the smallest local administrative division in France, governed by a mayor and a council) are exposed to cumulative nuisances, mainly north of Paris—essentially, Seine-St-Denis and Val-d’Oise. The west, the south, and Paris itself enjoy fewer nuisances and are inhabited by wealthy people. What are the determinants of such a distribution? Is it the attractiveness of a nice environment, or the avoidance of such nuisances? Put another way: is it the environmental “goods”, or the environmental “bads”? A report shows that in the Paris metropolitan region, nuisances and environmental degradation are the main reasons for people to move from the place they are living. Thus, the decision to move is strongly correlated to the desire to avoid environmental bads. This rejection is stronger than the attractiveness of environmental amenities (nature, silence, air and water quality, etc.). The question is: why? Why is the avoidance of real or imagined bad environmental conditions more decisive in explaining spatial distribution? Why does—in the case of the Paris region— the creation of amenities, green areas, or accessible ecosystem services have virtually no effect on attractiveness?

There are probably many reasons, and I hope that comments on this post will uncover a spectrum of answers. My answer is this: the environment cannot be reduced to those biophysical aspects that embody a proper functional integration of urban ecosystems. In France, so called “green spaces”, when coupled with social housing—as in Seine-St-Denis—are perceived by their inhabitants as buffer zones, created to separate them from the rest of the city. Conversely, the people living outside perceive them as dangerous areas frequented by rapists and dealers, as areas embodying fantasies about the social housing blocks. The result is that nobody ever uses these parks, even though they were originally designed to foster social and cultural intermingling, and to encourage social diversity. How ironic is that?

Maybe not so ironic—maybe perfectly in line with Parisian urban history. When Haussmann introduced greenery in the 19th century, one of his secondary objectives was to control the use of public space through a technical approach based on hygienism. The initiative’s main function was to bring more sunlight to the city and to better the air circulation. But, by doing so, the city’s life was marked by socio-spatial differentiation that was virtually segregative, embodied in a type of re-vegetation reduced to espaces verts. The very term espace vert (green space) instead of park or garden reveals its real nature: an indistinct area whose boundaries are decided in the abstract world of master plans. Nowadays, the same logic maintains itself: to separate, to distinguish, and to hide. The current regional master plan of the Paris metropolitan region proposes a quantitative objective of 10 m2 of public green area per inhabitant, as though it were sufficient to display a “green” label to become suddenly friendly and sustainable. The real issue is, does such a green label enable belonging and inclusion?

Indeed, one among the many challenges of urban sustainability should be developing the inclusiveness of the urban social fabric—a complex task—instead of adding parks and ecosystem services, which is relatively easy. Usually mayors, representatives, and other elected officials are not interested in improving what is already here, and they don’t like long-term commitments; their time horizon is usually the end of their term. There is no way to foster belonging and ownership in such a context.

Defining a good environment for green and just cities

To design both a green and just city, it is crucial to know what a “good environment” is for the people and the communities living there, one in which the enhancement of environmental conditions improves living conditions and facilitates new lifestyles. A polluted environment can be a place where life is good. Just think about the price of a square meter in the very center of very noisy and very polluted Manhattan, Paris, or London. Conversely, an environment with clean air and clean water can be quite intolerable, as evidenced by windswept, segregated social-housing blocks settled in the middle of nowhere. This logic was reflected at the beginning of the TNOC podcast, which noted that urban justice is not only about equity, fairness and distribution—to affordable housing, for example—but also about choice and inclusion, which goes with ownership and participation in decision-making.

Finally, it is about the right of the inhabitants to be creative and to build a beautiful environment. I could not agree more. It follows, then, that both “green” and “just” policies should include among their deciders not only elected officials and companies, but also non-market institutions, local communities, and individuals able to form self-determined user associations, according to the idea of Elinor Ostrom’s work, who showed that user communities can manage common goods quite well.

Nobody is saying that it will be easy, but these principles are a necessary prerequisite for fostering collective appropriation of environmental policies by the inhabitants. Governing and managing a city by definition is a “wicked problem”: a problem that is difficult or impossible to solve because of incomplete, contradictory, and changing requirements that are often difficult to recognize. Moreover, because of complex interdependencies, the effort to solve one aspect of a wicked problem may reveal or create other problems (Rittel and Webber 1973). Such problems are made all the more difficult because they combine environmental action and social justice. As Bruno Latour and Michel Callon beautifully put it in their seminal article, “Unscrewing the Big Leviathan”:

“There is no overall architect to guide it, and no design, however unreflected. Each town hall and each promoter, each king and each visionary claim to possess the overall plan and to understand the meaning of the story… Here and there one retires within oneself accepting the fate decided by others. Or else, one agrees to define oneself as an individual actor who will alter nothing more than the partitions in the apartment or the wallpaper in the bedroom. At other times actors who had always defined themselves and had always been defined as microactors ally themselves together around a threatened district, march to the town hall and enroll dissident architects. By their action they manage to have a radial road diverted or a tower that a macro-actor had built pulled down…”

Yes, fostering co-construction, inclusiveness, and ownership in urban policies is no picnic. But curiously, it usually works better when nobody tries to frame the procedure. It works better when nobody “looks”—when no public or private actor explains from the beginning to the population what the procedure should be, how people should act, and what should be their objectives. In my next post, I will present the case of a squatted wasteland in a poor place near social housing blocks—an environmental “bad”— that turned into a very popular park, combining leisure amenities and urban agriculture. In this case, an environmental bad was successfully converted into an environmental good precisely because no local authority or private company interfered. The inhabitants created this place by themselves, seeking their own objectives. In the end, the local authorities had no choice but to formalize what the community had already built.

Meanwhile, let me invite you to join the 5th Rencontres Internationales de Reims on Sustainability Studies and the Summer School that is part of it next June. We’ll specially consider how local communities can succeed in combining distributive justice, restorative justice, and interpersonal justice in developing urban agriculture.

Lessons on Post-Resilience from Venice, 2015

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

On day 1, I thought I could wait it out inside. On day 2, I got a little antsy, and bought 7 euro galoshes to pull over my brand new Doc Martins. On day 3, after springing a devastating leak in my right galosh while in shin deep water, I gave up and set out to buy stivali (boots). I was shocked to find a perfect pair for only 12 euros (about 15 dollars) at the hardware store on my corner, and that’s when it hit me: this is resilience, already in action, and right in your face. Thanks to their history, and their coastal position next to a rising sea, Venetians are used to storms, and know how work around them.

But are we all destined to need to make these kinds of changes?

Contemporary Venetian culture is heavily impacted by climate change. Two hours prior to every high water event, sirens followed by a sequence of eerie whistles sound throughout the city. The siren gets your attention, and the subsequent number of whistles tells you what the predicted high tide level will be. Each whistle indicates another 10 cm over 100 cm, the tidal elevation corresponding to 5 percent of the city under water. When you hear three whistles, as we did several times this week, 75 percent of the city is under water. When that happens, the city government deploys kilometers of passarelle (elevated wooden walkways) in the portions of the city with the deepest inundation. Shop owners place small barriers in front of every door, while continuing to hawk their wares. Sump pumps (that you never see) begin discharging water (of different colors) into the alleys through small plastic tubes, which you suddenly realize are all around you. And everyone, including the most dapper among them, sports boots. The young college girls wear black boots; the rugged delivery men where hip waders; the bridges and tunnels crowd, coming into Venice for work, wear garbage bags over their shoes. The Southeast Asian immigrants, who at other times of the year sell pocket lasers and fake Gucci bags, start selling boots and fluorescent galashes to the tourists in Piazza San Marco. But a basic pair of shin-high boots, like mine, gets you just about everywhere.

Walking through the flooded streets is another interesting experience. Everyone slows down—tremendously. It wasn’t initially clear to me why this was happening. Without cars, there’s always a lot of ground to cover in this city, and the average Venetian typically moves at a healthy gait. Feeling confident in my new stivali, I continued to move at this pace only to find out within a few minutes that I was suffering death by a thousand drops. It seems that each fast step kicks a few drops into the top of your boot. You don’t feel those individual drops, but keep it up and in a few minutes, your socks are soaked. I slowed down, realizing that alas, pazienza, everyone around me was used to this. When there’s acqua alta, it’s OK to be late, or to change the plan, or to cancel appointments. (Though, ironically, not for first graders. My daughter’s new teacher was careful to tell me that acqua alta is not an excuse to be late for school.) Venetians have adapted to contemporary acqua alta the way they adapted to life in a foggy lagoon over a thousand years ago. Life goes on despite it.

This said, the flooding is, of course, unpleasant. Though life continues, acqua alta is the subject of continuous conversation. At the supermarket, the woman in front of me on line at the cashier complains that the water level this morning was higher than was predicted by the sirens. The locals get extremely frustrated with tourists who block their way by stopping to take photos on the narrow passarelle. An elderly couple I encountered couldn’t get to the hospital to talk to their doctor because the vaporetto (boat bus) couldn’t fit under the Ponte dei Tre Archi due to the high water. In short, though Venetians have adapted, the situation is not welcome, and creates some very formidable challenges. Here is a city that is “stronger than the storm,” but definitely not voluntarily, and certainly not happily.

As I plod through the beautiful yet flooded streets, staring at the water ponded several inches on the marble tiles of cafés with delicious pastries in glass windows mere inches above the floor, I ask myself why our global culture can’t look at this example and make the changes necessary to avoid other coastal cities having to face the same fate. Sure, the vulnerable can try to adapt, and those with access to significant resources may, like the Venetians, achieve some level of resilience. But at what cost, and what fate faces those countries, cities, and peoples who can’t afford to build massive storm surge barriers, deploy kilometers of walkways, enforce new construction standards, or elevate critical infrastructure nodes? Why has the push for mitigation and the global cultural change necessary to significantly reduce emissions fallen so far behind the call for adaptation to an “unavoidable” future?

Yes, there is momentum in our emissions, and even if we stopped emitting greenhouse gasses today, a certain amount of change would still occur. And yes, it is politically naïve to think that there is any chance that significant cutbacks in global emissions will occur in a short time frame. For these reasons, we need to find ways to adapt to changes that are, in most cases, involuntarily imposed on us by an anthropogenically modified climate system (and especially in cities housing particularly vulnerable and economically challenged populations). But when will we pool our global resources and knowledge to develop true comprehensive global solutions to these problems?

There are some reasons to be cautiously optimistic. For example, I came across a recent New York Times article titled “Leaders in Davos Urge Quick Action to Alter the Effects of Climate Change,” and found it intriguing that participants of the World Economic Forum, for years the targets of anti-globalization protests for their perceived advocacy of trade liberalization and corporate profit over environmental conservation, worker rights, social justice, and other contemporary sustainability goals, have now “redoubled their calls to combat climate change.” And here in Italy, the Pope is known to be preparing an encyclical on ecology that he will deliver in the months leading up to the December 2015 United Nations conference on climate change in Paris. The expectation is that he will make the case that disagreements regarding the specific causes of climate change do not preclude the need for action. The pontiff is also expected to say that care for all creation, and healthy global ecology are the basis for global development and world peace, as recently reported in the National Catholic Reporter.

But while these and other statements from global economic and religious leaders may be encouraging, progress in the US, a country that a recent study by Concordia University suggests is responsible for 20 percent of the global warming observed through 2005, is dismally slow. Democrats seek action but are blocked by a powerful Republican lobby that doesn’t believe in anthropogenic climate change, or isn’t willing to consider legislation designed to reduce emissions significantly. In a hearing last week, Senator Ted Cruz, expressed concern that the recent focus of the National Aeronautics and Space Administration (NASA) on earth science (including climate science) is taking resources away from space exploration, what he considers to be its core mission. In January, the current leading Republican contender, Gov. Scott Walker, threatened to bring a lawsuit against the federal government if it passes legislation limiting carbon emissions from coal-fired power plants. And Florida, home to Jeb Bush, another Republican presidential contender, restricted its Department of Environmental Protection employees from using the terms “climate change” or “global warming” in official correspondence.

As the drops seep deeper into my boots, I get frustrated at the pace of our collective inaction on climate change. We can talk about how to live in unpleasant situations, or we can attempt to reduce the likelihood of making our lives unpleasant. Is there not a great deal of hubris in thinking that we mortals can become stronger than nature? As I reach home to my children’s happy voices, I wonder if we will learn that lesson early enough to keep their feet dry.

Lessons from Britain’s Urban Nature Movement

Art, Science, Action: Green Cities Re-imagined

A review of Nature in Towns and Cities, by David Goode. 2014. William Collins, New Naturalist Library. ISBN: 9780007242405. ISBN 10: 0007242409. 417 pages.

Nature in Towns and Cities cover

The newest title in The New Naturalist Library, Nature in Towns and Cities by Dr. David Goode, is true to the series’ dual goals of “recapturing the enquiring spirit of the old naturalists” and “maintaining a high standard of accuracy in presenting the results of modern research.” Goode’s scientific background, deep personal interest in urban nature, and long-term involvement in, and advocacy for, Britain’s urban nature movement has created an entertaining and intellectually stimulating read for professional urban ecologists, planners and practitioners, amateur naturalists, and grass-root activists. While the book is specific to Britain, its descriptions of the ecological principles and the manner in which the urban conservation movement has grown over the past three decades, in Britain and beyond, are universally relevant.

Goode, with more than forty years’ experience as ecological advisor to local and regional governments, director of the London Ecology Unit, and Head of Environment at the Greater London Authority, is eminently qualified to document the urban conservation movement, including his own role as exponent, in Britain and abroad. But, beyond the institutional, political, and social factors that have contributed to changing attitudes toward urban nature, what makes Nature in Towns and Cities a practical and enjoyable read is Goode’s keen knowledge of natural history dating from the time he became a curious naturalist at the age of fourteen. Nature in Towns and Cities isn’t Goode’s first book on urban nature. His Wild in London inspired a generation of urban nature enthusiasts in the mid-1980s.

Wild in London

The Nature of Towns and Cities

Goode opens with “Nature In A Small City”, a description of British habitats through a tour of his home town of Bath, where plants and animals inhabit “deep basements and small courtyards”, sunbaked walls where leaking drainpipes and holes in masonry provide microclimates for lichens, ferns, and spiders; Peregrine falcons utilize a church steeple; and ancient graveyards, “with their rich humus and ample nutrients, support a rich array of native flora.” He offers the reader colorful and intimate illustrations whereby even in a built-up small town, a vast array of habitats host species that belong to native sites that have been engulfed by urban development and other species that are utterly unique to the urban scene where wildlife and plants live “cheek by jowl” with people. Bath, as a template city, represents a microcosm that is representative of similar towns and cities across Britain where densely built up cities, surrounded by suburbia, offer a patchwork of green spaces, wetlands, streams, rivers, and green corridors. All of these special habitats yield an amazing amount of biodiversity from city centers to the surrounding rural landscape.

Organization of the text

Two themes run throughout the book: scientifically sound descriptions of urban natural history through an ecological lens and a detailed recapitulation of the growth of the urban nature conservation movement. In “Urban Habitats” Goode methodically describes the ecology of “encapsulated countryside” woodlands, meadows, marshes, heathland and hillsides that have been subsumed and form a remnant of the surrounding rural landscape within the urban matrix. He describes the biota, both native and non-native, that has colonized canals, cemeteries, abandoned and active railways, post-industrial landscapes, “new” created wetlands, and concludes with more prosaic urban parks, squares and cemeteries. Goode provides examples of the influence of socio-economic and political factors in shaping urban habitats. For instance, he describes the manner in which “encapsulated woodlands” were transformed following the industrial revolution and in response to changes in transportation, particularly the national railroad network, and abandonment of traditional coppicing following adoption of coal for residential heating.

Colonisers And Specialists” focuses on: birds new to the urban scene—“a motley crew” of opportunists; badgers and foxes; and pigeons, sparrows and swifts. A passion for urban nature, citizen science, keen natural history observation, and detective work are all illustrated in descriptions of a changing lifestyle of urban badgers since they attained protected status in 1973. What started as a colony of badgers concentrated in a small graveyard in Bath is now a badger population occupying more than 400 cities and towns across Britain, taking advantage of myriad habitats from wooded banks and gardens to golf courses. Anyone engaged in urban canid-human interactions will recognize challenges of managing the explosive colonization of urban foxes throughout Britain. The use of “swift towers”, “swift-bricks”, and nesting “boxes” in new building construction or retrofit projects will also resonate with those who have worked to introduce or reintroduce swifts into the urban environment.

I found “Post-Industrial Ecology” to be especially interesting and relevant given the modern rush to repurpose brownfield sites for new industrial development. Goode makes a strong case for investigating the ecological value of post-industrial sites, no matter how contaminated, before proceeding to industrial reuse. Goode describes how Buglife, one of the myriad NGOs at work protecting brownfield sites for their unique ecological values, created a best practices guide for planners and developers that describes the importance of invertebrate species and the benefits of ecological landscaping to protect them. He also provides several examples where endangered or threatened species, with their narrow ecological requirements, have colonized highly alkaline or acidic sites in a “Tour of Britain’s Wastelands.” Goode describes the importance of gravel pits, disused wharves, canals, and railways for providing a patchwork of plant communities that offer a range of successional patterns within the urban matrix.  He argues that urban “wastelands” are the “essence of urban ecology.”

Urban nature conservation

002“Urban Nature Conservation” traces the changing philosophy regarding the role of conservation in the urban context, a shift he persuasively declares as “one of the most important ecological movements in the past half-century.” He follows the urban conservation movement from establishment of the Nature Conservancy in 1949—to protect the “gems of British wildlife” when little or no attention was accorded urban nature—to the eventual recognitions of the value of nature to humans and their longing for connection to nature where they live, work and play. Eventually, these shifts led to an explosion of interest in urban nature conservation. Goode recounts the origins of local natural history societies that sprang up during the Victorian era in cities such as Liverpool, Manchester and Bristol.

In the post war era many of these volunteer, amateur societies turned their attention to protecting urban natural areas. In the 1970s professional urban planners and landscape designers turned their collective attention to urban areas. Goode gives a great deal of credit for the surge of interest in urban nature to Ian McHarg’s Design with Nature, Richard Mabey’s The Unofficial Countryside, and contributions from the U. S. in the form of John Kieran’s Natural History of New York City (1959). But it was The Endless Village, a publication of the Nature Conservancy Council (NCC), that Goode argues “changed the rules overnight” by dispelling the myth that cities represented “ecological deserts.”

The 1980s: time for action

Anyone who has worked on urban nature conservation will relate to the assertion that, in the 1980s, urban conservation went viral across Britain with local conservation agendas leading the way. Goode uses a fight over a scrap of disused railroad property, the Gunnersby Triangle, to illustrate the rise of “Friends” organizations dedicated to the protection of small, locally important nature sites. A site of little ecological value in the traditional sense, the Triangle nonetheless became a cause célèbre due to its importance to the local population. Today it’s one of the London Wildlife Trust’s most important urban preserves. The 1980s saw an  explosive growth of urban conservation groups and the integration of urban nature into formal urban planning schemes across Britain, a pattern repeated in the United States.

Urban planning

In “Urban Planning” Goode describes his own work as London’s first ecologist for the Greater London Council which was created in 1982. Goode and his ecological team were tasked with three primary functions: developing policies for ecological and nature conservation for London and the surrounding boroughs; establishing an ecological database for London; and providing ecological input and advice on issues related to land use planning and management of publicly-owned land. The team published a number of influential “nature conservation guides” for London and its surrounding boroughs which serve as excellent planning templates to this day.

Creating new habitats and planning for nature

Going above and beyond their mandate, Goode and his colleagues also participated in the development of ecology parks and nature centers. A premier example was the creation of Camley Street Natural Park which demonstrated the feasibility of creating a new wetland park out of what had been a derelict coal tip adjacent to the Regent’s Canal, literally a stones throw away from King’s Cross tube station. Not only did the creation of Camley Street demonstrate that new habitats, in this case a wetland, could be created amidst the most urbanized of urban environments but it also showed how a bit of green could be provided for children occupying nearby low-income housing. Camley’s success sparked urban revitalization projects across Britain and was the inspiration for similar efforts in Portland, Oregon and elsewhere in the United States.

Nature in Towns and Cities includes an overview of the many international conferences, publications, and key innovators who succeeded in bringing the urban conservation movement into the mainstream. Goode also describes the evolution of London’s Nature Conservation Strategy, which, for the first time, introduced nature conservation as part of land use planning for London. The process the team of ecologists employed to inventory almost 2,000 sites not only painted a comprehensive picture of the city’s ecology but provided a template of a rigorous science-based approach to documenting the ecologically significant landscapes that is as relevant today as when they undertook the process in 1982.

One of the London Ecology Unit’s most important contributions to urban nature conservation was the development of a three-tiered hierarchy of ecological sites:  London-wide; Borough-wide; and Local. Their work identified over 140 “Sites of Metropolitan Importance for Nature Conservation” (London-wide). Surveys were also performed for 31 of the 33 London boroughs that resulted in the establishment of 1,300 “Sites of Borough or Local Importance” that together with sites of Metropolitan-wide significance represented almost 20 percent of the London area’s land base. All of this information has been described in thirty-one Ecology Handbooks published between 1985 and 2000, which constitute partial basis London’s biodiversity strategy today.

Access to nature, Biodiversity Action Plans, green infrastructure, ecosystem services, and new ecological landscapes

A conundrum for cities across the world is how much urban nature and greenspace is enough? What, in Tim Beatley’s Biophhilic Cities parlance is the “minimum daily requirement of nature?” Do we assess access to nature in hectares per capita, in quality of habitat, or rarity of habitat? One approach Goode describes is a national accessibility to nature standard developed by Natural England, which recommends at least two hectares in size within a five minute walk from home and at least one hectare of a site with the quality of a Local Nature Reserve per 1,000 population. He then describes London’s “Areas of Deficiency in Access to Nature”, which planners are using to identify where ecologically important sites can be improved, where points of accessibility can be expanded, or where new sites need to be created.

The final chapters cover a host of emerging concepts in urban ecology including valuing nature’s ecosystem services and the creation of large new urban wetlands such London’s Wetland Centre which attracted 135 species of birds in its first year after construction. Nature in Towns and Cities ends with a description of the newest effort to introduce greenspaces into city centers through the creation of green roofs.

Whether you share The Guardian’s assertion that Nature in Towns and Cities is “probably the finest work on urban ecology ever written” (December 6, 2014), there is absolutely no doubt you will agree that it’s an essential addition to any serious urban naturalist’s library and an essential and inspirational guide to planning for urban nature in your own city, town or region.

***

Rating Nature in Towns and Cities:  I highly recommend the book to the lay audience, urban planners, park planners, urban conservation advocates, and natural resource managers. I give Nature in Towns and Cities a five (flawless and fantastic) in The Nature of Cities parlance, even though some might find the Britain-centric nature of the book to be a slight disadvantage.

The book is full of high quality color photographs that illustrate the text. There are also excellent graphs, charts, and diagrams that accompany the quantitative oriented text. It’s hard to imagine what Goode might have left out, given its comprehensive nature. Even though these are evolving concepts he covers the ecological importance of green roofs, green infrastructure and the concept of ecosystem services. His references to important people and publications in the urban conservation movement provide seasoned veterans with inspiring reading and new-combers with motivating material to urge them into action in their own cities or towns.

Neighborhood Planning for Resilient and Livable Cities, Part 2: Can ‘Nested’ Neighborhood Planning Lead to Urban Ecological Democracy?

Art, Science, Action: Green Cities Re-imagined

Is neighborhood planning worth doing? We argued in our last blog entry (Part 1 of this series) that neighborhood planning has the potential to be transformative in improving community resilience, but that it also has a dark side. It can be divisive both spatially—by setting clear geographic ‘limits’ that signal exclusion or exclusivity—and socially, by putting local interests ahead of broad concerns such as urban connectedness and complexity. In this follow-up blog, we propose that neighborhood planning is worth doing if it integrates four key components of ‘nested’ neighborhood planning that link neighborhood-scale planning to the work of ensuring better outcomes for the city as a whole: (1) social innovation, (2) community-development practice integrated with theory, often simply termed ‘praxis’, (3) neighborhoods without borders, and (4) a vision of ecological democracy.

These four components are based on our practical experience with neighborhood planning and our examination of academic and professional literature on planning and community development. We speak normatively here, in terms of what ought to be done. We outline a multi-scalar approach that links dimensions of thinking, planning, and building which are often disparate: integrating scales from the neighborhood to the city to the city-region, integrating action across domains of civil society and the state, and integrating value systems of urban ecology and participatory democracy. In our next and final blog entry of this series, we will present a Montréal case study, and examine whether nested neighborhood planning can offer building blocks for better cities in a wide range of geographic, political, and cultural contexts, if all three types of integration are present.

Neighborhood planning component 1. Social innovation

Social innovation is both a new label for old practices and a significant new notion. As a concept, it has evolved in two important ways: (i) to make the connections between tangible ‘bottom-up’ actions where people take their own initiatives to effect change and much-needed transformations in governance; and (ii) to provide meaning that is both usefully ideological and critically robust, so that it can play an active role in debates of politics and social science (Nussbaumer and Moulaert, 2007: 73-78; in Moulaert et al., 2010: 7). How can we understand the dynamics of social innovation at the neighborhood level? Useful frameworks are found in a collection edited by Moulaert et al. (2010) titled Can Neighbourhoods Save the City? Community development and social innovation, in which contributions from various authors uncover the conditions and prerequisites for making neighborhood-scale initiatives pertinent at the city scale and beyond. The editors contend that ‘socially innovative neighbourhood initiatives’ share three objectives:

  • to satisfy human needs which are unmet by the state and markets;
  • to provide access rights which enhance human capabilities and are empowering to people and social processes; and
  • to change social relations and power structures that lead to more inclusive governance.

In their case studies from 10 European cities, the authors show how neighborhoods can be pivotal sites for driving social innovation, which typically happens through civil-society organizations (CSOs) working not only within local neighborhoods, but also working to connect them with the broader urban context, building bridges to the political realm. A vital success factor in the cases was a capacity and perspective of glocalism, or integration of spatial scales from neighborhood to city to global. A glocal perspective reminds us that ‘localist’ initiatives hold local culture and community interests as exclusive or predominant forces for determining development; this hinders the trans-local relationships, policies, and processes crucial for resilient and livable cities (Rohe, 2009; Moulaert et al., 2010).

Photo1_city_mined
City Mine(d) and its urban pop-up projects in Brussels, London, and Barcelona provide an example of ‘glocal’ action, as an international network of individuals and collectives involved with city and local action. Photo: citymined.org

In our own work, we have found another key reason that socially innovative organizations are poised to contribute to resilient and livable cities through neighborhood-based planning. We call this the expectations-motivation differential. This refers to a dichotomy: it is often in the (rational) interest of state institutions to keep the expectations of citizenry low, whereas progressive civil-society organizations seek to ‘raise the bar’ by inspiring people to have higher expectations for the collective work of city-building. In this perspective, the aim of planning is to inspire and educate people about possibilities for the city, and to explore the possibilities for learning and positive change at the local scale. When ordinary people feel empowered to plan for change in their own neighborhoods by critically assessing the current context, analyzing power dynamics and external forces, understanding that ‘a different city is possible’, and planning for a better future, it stands to reason that they will be more likely to take part in collective action for social change, thereby contributing to creating a more resilient and livable city.

Neighborhood planning component 2. The praxis of community development 

The notion and praxis of ‘community development’ can be defined as thoughtfully designing, continually learning from, and creatively acting on processes of collective engagement associated with neighborhood planning. In other words, we need to strive for social learning by designing engagement processes that lead to knowledge creation, which can be translated into action that will feed the continued refinement of engagement processes.

Our notion of community-development praxis is influenced by work found in several bodies of literature including collaborative and participatory planning, community development, education and social science. We particularly value the idea of ‘phronesis’ or ‘practice-based wisdom’. To unravel what we mean here, we draw on Ledwith (2011a) to start with the notion of praxis as a synthesis of practice and theory, reflection and action, thinking and doing; we can then speak of critical praxis, which refers to the collective endeavor of making sense of the world and our own actions in order to transform it. Through praxis people gain critical awareness of their own condition and collectively work to shift balances in relationships of power in order to work toward social justice, empowerment, and liberation.

Paul Piccone calls praxis “that creative activity which reconstitutes the past in order to forge the political tools in the present to bring about a qualitatively different future” (1976: 493); similarly, Innes and Booher (2010: 89) suggest that

“… [e]ffective collaboration depends on praxis. That is, it depends on extended practical experience deeply informed by theorizing and reflection. Those who engage in collaboration build their capacity and intuition about how to proceed, while at the same time building theory about when and how collaboration can work. Praxis is practice interwoven with theory and theory informed by experience in the spirit of pragmatism.”

Margaret Ledwith (2011b) describes community development praxis as a ‘contested space’ between top-down and bottom-up approaches in which state and civil society participants continually negotiate their ways of working together and challenging one another. Drawing on Flyvbjerg (2001), she has argued that praxis ought to intermingle with phronesis, an approach to social science that emphasizes practical knowledge and practical ethics, which are based on context-dependent, pragmatic action and practical value-rationality (Ledwith, 2011a). Thus, the praxis of community development is unabashedly value-laden. Its aim is collective action for social change, and it is principled on social justice and a sustainable world, a critical analysis of power, and popular education for participatory democracy (Ledwith, 2011b; Ledwith and Springett, 2010).

If neighborhood planning processes are to be transformative in their capacity to contribute to more resilient and livable cities, they must be based on a strong ethos of community development (comprising both physical transformations and the qualitative development of individuals). If community development is to be carried out effectively, sustainably, and in a transformative way, the associated processes of local governance must be participatory and collaborative, building improve neighborhood capacity to manage change over time. This means that neighborhood planning processes must enable community members to mobilize their existing skills, reframe problems, work cooperatively, and use community assets in new ways. Principles of self-help, self-organization, and participation can guide flexible processes of revisiting neighborhood plans over time in order to identify concerns, continue dialogue, explore alternatives, reconsider priorities, and take effective action.

Neighborhood planning component 3: Neighborhoods without borders

A neighborhood plan typically defines an urban district and its boundaries (which might be natural or built elements, such as rivers, steep slopes, railroad tracks and/or large parks). Often the ‘official’ limits for planning follow some kind of public right-of-way, such as streets, roads, and highways. Municipal boundaries often run down the middle of rights-of-way, thus dividing these public spaces into separate jurisdictions. The logic here is not merely convenience or efficiency; it has long been presumed that clear neighborhood edges are needed in order to make neighborhoods ‘legible’ and to provide distinct, easily-recognized character (see e.g. Banerjee and Baer, 1984; Lynch, 1981; Perry, 2007 [1929]).

Our proposition of ‘neighborhoods without borders’ challenges the conventional wisdom of neighborhood planning in North America—that is, the usual prescription that neighborhoods be clearly demarcated by physical edges (usually arterial roads), derived from Clarence Perry’s ‘neighborhood unit’ as discussed by Banerjee and Baer (1984), Greenberg (1994), and Keating and Krumholz (2000). Instead, we argue that neighborhoods should be defined to encompass not only a range of activities, including housing, businesses, and community services, but also the public spaces of arterial and commercial streets often relegated to the outside margins. Neighborhoods defined as overlapping or nested configurations prevent the ‘spaces in between’ prone to becoming zones of social and spatial marginality. This situation is often exacerbated by superhuman-scaled arterial roads that can threaten the safety of residents and urban quality of local neighborhoods, contributing to health problems through pollution and accidents while often reducing opportunities for better integration of nature and biodiversity in dense urban environments.

Some argue that the spaces ‘separating’ neighborhoods should be a different category of space unto itself devoted to serving larger city functions. The logic could be seen as that of the ‘city efficient’ of the early 20th century, where activity areas were separated from transportation zones containing high-capacity roadways (see e.g. Van Nus, 1979). We instead argue that these ‘in-between zones’ should be defined as part of neighborhoods, enabling stakeholders to challenge the power structures that govern these spaces based on an understanding of how they are integral to creating better neighborhoods and cities. In a city of neighborhoods characterized by resilience, livability, and people-centered urban design, the whole cannot be greater than the sum of its parts. Cities must be seen holistically as containing overlapping and nested neighborhoods. Those parts should include a range of uses and street types; they cannot be an expression of formally or informally ‘gated’ enclaves—the solipsistic ‘burbclaves’ chillingly described by Neal Stephenson in his dystopic 1992 novel Snow Crash.

Good neighborhood plans should strengthen the public realm of neighborhoods. These shared spaces tend to garner attention, enthusiasm, and collective action, and we cannot forget that the largest share of public space in cities is occupied by streets. It could be argued that neighborhood streets represent the greatest opportunity for transformation in policy and practice toward building better cities. By rethinking our streets and the wide set of externalities that result from their construction, configurations, and use, we can reimagine how these spaces can provide all sorts of beneficial functions: more space for people walking and bicycling; vegetation and other forms of biomass, including urban agriculture and biodiversity corridors; playgrounds and the urban ‘living rooms’ seen in great cities large and small around the world (for examples, see Beatley, 2011; Gehl, 2010; Newman and Jennings, 2008; Register, 2006; Whyte, 1980).

This prescriptive component is about rethinking how public spaces—specifically streets—in cities are used in an attempt to reverse over time the tendency to carve up cities with highways and instead to think of how these spaces can better integrate neighborhoods to redefine routes in cities so that they can better serve not only the needs of people walking, cycling, and using mass transit, but also as routes that can better facilitate increased nature and biodiversity.

It is important to clarify what we are not arguing. We do not contend that cities ought not to have clear edges. Clear boundaries around cities can be vital to contain urban sprawl and to provide good access to nature and biodiversity. We do not argue that resilient and livable cities must be based on specific templates for neighborhood design. Rather, we are asserting that the neighborhood is an appropriate scale to effectively plan for better cities, particularly in already-built contexts.

Neighborhood planning component 4. Holistic ecological democracy vision

There is far more to resilient and livable cities than physical attributes. If there is no mechanism for the democratic engagement of citizens at the neighborhood scale to create better cities, no combination of good policies and planning will make a difference. Setting a vision for a better city from a neighborhood perspective is critical to bringing people together to organize collective action that will bring about social change. Neighborhood plans should contain a practical utopian vision for the neighborhood within the larger city, which is translated into medium-term policies and programs but also actions that can be taken on a short-term timeframe.

A holistic vision for a resilient and livable city is one of integral neighborhoods within an ecological democracy. By integral neighborhoods we mean what Richard Register and Paul Downton call ‘urban fractals’ or “portions of the city that embody the essential functions of the whole city on a smaller scale” (Register 2006: 128). Integral neighborhoods contain a mix of land uses to provide for housing and jobs, shops, and small manufacturing facilities. Key attributes include compact urban form, socio-economic diversity, organic agriculture, rooftop uses, and pedestrian-oriented streets. The natural and neighborhood environments relate synergistically, and biophysical characteristics, such as sun and wind conditions, play central roles in architectural and urban design and contribute to energy conservation. Compact design and mixed land uses provide for access by proximity, meaning that safe, affordable housing is provided near employment and services in ways that minimize car dependency and energy use (Register, 2006; UNEP, 2012).

Randolph Hester’s (2006) notion of ecological democracy is the joining of urban ecology with participatory democracy; in the specific endeavor of designing better neighborhood and city form, it is particularly useful for our discussion:

“Ecological democracy, then, is government by the people emphasizing direct, hands-on involvement. Actions are guided by understanding natural processes and social relationships within our locality and the larger environmental context. This causes us to creatively reassess individual needs, happiness, and long-term community goods in the places we inhabit. Ecological democracy can change the form that our cities take, creating a new urban ecology. In turn, the form of our cities, from the shape of regional watersheds to a bench at a post office, can help build ecological democracy.”

How is the neighborhood scale important to the lofty aspirations of ecological democracy? Hester (2006: 32) argues that this is the “domain of deliberative face-to-face ecological democracy.” It is through everyday experiences in the everyday environments of neighborhoods that social change occurs. However, given that the concept of (radical) ecological democracy may not be workable within the context of many countries, is it helpful to bring this vision into the dialogue of neighborhood planning processes?

We argue that it is precisely through participatory practices such as neighborhood planning for resilient and livable cities that we can raise expectations of the public and work to bring about social changes necessary to realize the kinds of neighborhoods for the cities we need. In his book Envisioning Real Utopias, Erik Olin Wright (2010) sets out a set of models for social transformation that are instructive for thinking about how we can achieve better cities. Depending on the wider political and institutional context of a place, strategies for transformation will vary. In most cases strategies can be seen as processes of change in which fairly small transformations contribute cumulatively to a qualitative shift in the logic and dynamics of larger social systems. In terms of neighborhood planning, these metamorphoses occur in what we have described above as the contested space of community development praxis between top-down and bottom-up. This is the space where civil society and the state meet—and cooperate (or not) to some degree, even if certain citizen stakeholders are sometimes completely excluded from official planning processes. Exactly how social transformation comes about is highly context-dependent.

Whatever the political, cultural, or institutional context, most people around the world live in some form of neighborhood. The variations are great in terms of what those neighborhoods look like, how they function, and whether they contribute to creating better cities. What is true for all neighborhoods is that they are fundamentally defined by (and for) people. When people decide to come together to work for change, great things can happen.

In our final blog entry (Part 3 of Neighborhood Planning for Resilient and Livable Cities), we will examine how a Montréal civil-society organization successfully undertook neighborhood planning and what can be learned from this experience for making better cities around the world.

Daylighting and restoring urban streams, ponds and wetlands can provide huge ecological and social benefits. Are such restorations “worth it”? What are the pitfalls? How can we demonstrate these benefits and elevate them in the public discourse so that urban wetlands become urban planning priorities?

Urban stream restoration has been in practice for over 30 years, with early efforts in the Chesapeake Bay watershed and California. In recent decades, other U.S. cities have joined in, including New York City and nearby suburbs; Boston; Los Angeles; Kalamazoo, Mich.; and San Luis Obispo, California, with many more in the planning and development stages.

Among the stream restoration practices is the daylighting of a stream or small river that has been covered over. Among the best known examples is in Seoul, South Korea, where the Cheonggyecheon stream—a once-pristine waterway that, by the 20th century, had turned into an open sewer—was buried under layers of highways and other urban systems. The city peeled away layers of roadway, exposing and restoring the stream bed and making it the centerpiece of an enlivened neighborhood, where children play in the clean waters (fed by a mechanical system) and plant, insect, bird and fish species proliferate, despite the extensive engineering.

Yonkers, New York (just north of New York City) has an example of daylighting a buried stream. The Saw Mill River, which housed the eponymous mill that used hydropower to cut timber, was covered over by the city and encased in a flume to hide the dirty waters that flowed through it. Recently, the city celebrated the completion of the first phase of daylighting of the Saw Mill, which did not demolish the circa 1925 flume, but instead diverted water from it into a new river bed which flows through the heart of the city, where a parking lot once covered the river.

Nearby, in the Bronx, a bold new daylighting project is in the planning stages. The goal of this project is to remove Tibbetts Brook from New York City’s combined sewer overflow (CSO) system, into which it is currently piped. Tibbetts Brook drains a 2,508-acre watershed that consists of most of Van Cortland Park in the Bronx and Tibbetts Brook Park in Yonkers.  The Brook is a natural tributary to the Harlem River, but for almost a century the entire stream has been piped to Broadway, several blocks to the west, where it mixes with sanitary sewage and is pumped nearly seven miles south to a waste water treatment plant. Removing the stream from the CSO and daylighting it by restoring a section of the stream to an open, vegetated channel, will reduce the combined sewage overflows to the Harlem River, restore ecological functions to a buried stream, enhance open space and environmental experience, and increase the resiliency and operational flexibility at a waste water treatment plant.

Removing the Tibbetts Brook stream flow from the combined system would provide significant relief to the CSO system in addition to providing multiple other benefits. The restoration of the creek as a tributary to the Harlem River could reduce flow entering the CSO by up to 240 million gallons per year and could reduce the number of CSO events occurring on the Harlem River by approximately 15%. In addition, daylighting the stream through Van Cortlandt Park and along the street and adding a proposed greenway could create new economic, educational, cultural and recreational opportunities and provide aquatic and riparian habitat together stormwater detention and treatment.

Despite the clear benefits of not directing the entire stream system from this largely forested watershed into the CSO, the City has not made any prior efforts to correct flawed hard engineering solutions. Currently, the NYC Parks & Recreation Department is working with the City’s Department of Environmental Protection, which oversees the water supply and sewer system, to evaluate alternatives for Tibbetts Brook.

Will the City take the bold step to daylight the stream and create the stacked benefits of green infrastructure, or go for the more “cost effective” but one-dimensional move to simply use a lake in the park as a temporary holding facility, keeping the level low but allowing it to fill higher during storm events and channeling the overflow through traditional gray infrastructure to the treatment plant? The decision could mean a lot to the quality of life of local residents—and their animal neighbors.

Urban stream restoration: a catalyst to improving biodiversity and quality of life

Urban stream restoration is an interesting subset of urban ecological design because its value sits so squarely between cultural and ecological benefits. The sheer poetry of freeing water from the rusty confines of subterranean pipes and raising it into a cultural amenity that brings the natural world to urban residents (daylighting) is irresistible to the landscape architect in me. As a restoration ecologist, I am also keenly aware that many urban stream restoration initiatives, including most daylighted streams, rarely have the ability to restore the full suite of physical and ecological processes associated with them.  But this doesn’t matter.  What matters is that we use every opportunity we can to restore urban streams and wetlands to the best of our ability to improve both the places we live, work and play along with the receiving waters these systems feed.

While many urban stream restoration and stream daylighting initiatives focus more on aesthetic and cultural benefits, an often-missed opportunity is the chance to enhance urban hydrology, water quality and biodiversity.

An often overlooked but critical component to any stream is its adjoining floodplain.  Floodplains are the hydraulic relief valve for streams, attenuating flood flows, recharging groundwater, assimilating nutrients and harboring many species of flora and fauna.  Without access to floodplains, stormwater runoff is often trapped in the stream channel, causing increased erosion of the channel bed and banks, degraded water quality and loss of in-stream habitat. Understandably, in many cases the idea of restoring an urban channel and its adjoining floodplain are all but impossible due to space constraints. But that should not stop us from trying to restore floodplain functions back into these projects.  Truncated (or sporadic) floodplains, alternating flow regimes, recharge areas and reestablishing a native plant community along the stream’s edge can all contribute to restoring the functions and values associated with lost floodplains.

Another aspect of urban stream restoration and daylighting is its ability to be integrated into a more holistic program to improve water quality. Stormwater runoff from buildings, paved streets and other hard surfaces in urban areas carries with it a toxic mix of nutrients, heavy metals and hydrocarbons. Untreated, this runoff enters storm drains, channelized streams and ditches, which eventually drain to downstream water bodies like rivers, lakes, estuaries and oceans. Combined with stormwater best management practices throughout the watershed, urban stream restoration provides a great compliment to improving water quality for both human consumption and fisheries.

Finally, urban streams often serve as the only vestiges of once thriving natural habitat left in urban settings. Too often the primary purpose of restoring urban streams is to improve water quality or to enrich the cultural or aesthetic value of nearby property. Wildlife along with migratory and resident birds need these corridors of remnant vegetation to meet their life requisites. This habitat is rendered even more important because riparian corridors often offer the only connection between larger patches of green space such as parks.   Studies have shown that restored and daylighted urban streams that purposively build-in both physical and hydrological complexity found in natural streams will support a greater array of wildlife including amphibians, mammals, reptiles, insects and birds of all kinds. One example is the presence of wood. Decaying wood in stream systems adds carbon and fuels the growth of aquatic insects and other microbial organisms. This in-turn provides food for many of the larger aquatic species that support a more divers and interesting urban food web.

Restoring and daylighting urban streams can improve water quality, support riparian zones rich in native plants and wildlife, regulate water flows and floods, and can create landscape connectivity as the backbones of urban habitat corridors. While few single urban stream restoration initiatives afford the opportunity to realize all these benefits, that doesn’t mean we shouldn’t try. Supporting multiple ecological benefits, regardless of the initial impetus for a project, will allow us to restore ecological balance in urban areas.

Recently, Gilbert Rochecouste, a placemaker, proposed that Williams Creek, channelled in a stormwater drain under Elizabeth Street in the centre of the city of Melbourne, Victoria, Australia, should be daylighted. The proposal was described as “unfeasible” by the city council.

How can we advance the cause of daylighting and restoration of urban streams, ponds and wetlands? One way is to demonstrate their benefits and evaluate them in monetary terms. We need to develop the business case. The benefits are often expressed as economic, environmental and social. Laura Musacchio, an American landscape architect, suggests that we should broaden this triple bottom line to 6 E’s for sustainable landscape design: economic, environmental, equity, (a)esthetic, ethical and experiential. (The scientific basis for the design of landscape sustainability: A conceptual framework for translational landscape research and practice of designed landscapes and the six Es of landscape sustainability. Landscape Ecology, 2009, 24, 993–1013).

Let’s look at what is known about these benefits. If we know what they are, we can more easily put a dollar value on them, for those interested in the business case.

For the moment, let’s put aside the economic benefits, with the assumption that they will be evaluated. Some of these benefits have markets, e.g. fishing, and can be evaluated easily. Some non-market economic benefits, e.g. ecotourism, can also be evaluated with methods such as ‘willingness to pay’. It’s the evaluation, in dollar terms, of other non-market benefits that’s tricky. Many of those benefits derive from the other Es. Let’s consider them.

Environmental benefits must be self-evident, surely: increased biodiversity, improved water quality, reduced urban flooding, aquifer recharge, improved urban microclimate, etc, etc. Some of these can be evaluated economically, e.g. value of insurance claims prevented by restoration of wetlands to reduce urban flooding. Some cannot, e.g. intrinsic value of biodiversity.

Benefits involving equity, aesthetics, ethics and experience of waterways and wetlands generally do not have markets to inform their evaluation. Nevertheless, these benefits are increasingly acknowledged and the subject of research in many countries. Much of this research is based around the theme of well-being and has shown the critical importance of urban nature, accessible at creeks and rivers, ponds and wetlands, to human well-being, contributing to psychological restoration and improving health. Some of these benefits derive from experiencing the landscape. Other benefits result from the improved thermal comfort of the urban landscape as a result of the vegetation and water within it. The presence of water also provides benefits associated with opportunities for passive and active recreation.

The aesthetics of the waterway or wetland are important in perception of the benefits. Not everyone uses the same aesthetic when they look at the world. There are at least four ways of looking at landscapes, discussed by Paul Gobster, Joan Nassauer, Terry Daniel and Gary Fry, in their very interesting paper titled “The shared landscape: what does aesthetics have to with ecology?” (Landscape Ecology, 2007, 22, 959-972). People using a scenic aesthetic look for beauty in the landscape, whereas those using an ecological aesthetic look for dynamism, ecological function and health. A tension exists between these two aesthetics, for both can interpret the landscape as ‘natural’. In scenic landscapes, perceived naturalness might not reflect the scientific notion of naturalness, which is valued by the ecological aesthetic. An aesthetic of care and effect of knowledge values signs of human care and intent in the landscape, and an aesthetic of attachment and identity values cultural landscapes that reflect place attachment and identity.

Which of these aesthetics, then, might be used when looking at restored waterways and wetlands? How might the different aesthetics influence their perception and value? I would suggest that waterways and wetlands can be viewed favourably with any of these aesthetics, so that they are appreciated and valued. Context of the waterway or wetland in the landscape is all important, as are the personal characteristics of the viewer, including knowledge and familiarity. However, the scenic aesthetic and the aesthetic of care and effect of knowledge might not always yield favourable perceptions. Not all creeks, rivers and wetlands are beautiful and many can look messy and uncared for, particularly in an urban context. This potential pitfall, though, can be overcome with attention to the design and maintenance of the restored landscape, to suggest that any apparent ‘messiness’ is intended, and by promoting familiarity and understanding of these landscapes.

So we return to the pesky problem of providing a business case for the daylighting and restoration of urban streams, ponds and wetlands. We must look to the economists to evaluate in dollar terms the myriad non-market values of the benefits of these waterbodies. I know that they are working on this, for example within the Cooperative Research Centre for Water Sensitive Cities, based in Melbourne, Victoria, Australia.

In addition, we must encourage everyone to discuss this issue, so it is already part of the public discourse when we have the business case to make it a priority in urban planning.

Making our urban hydrologic systems visible not only makes economic and environmental sense it also has major cultural ramifications as well. Swamps, streams, springs and rivers contained and channelized to facilitate development give us a false sense of security that the forces of nature can be easily controlled by hard engineered solutions. While this may be true for a particular moment in history, the forces of nature are variable and with climate change the limits of these systems are also being tested and challenged more frequently.

If we look at the geology of New York City and the hydrologic mapping of Eduard Viele interesting patterns become apparent. High-rise buildings populate areas where the bedrock could support them. Lower buildings occupy areas that were historic marshes, mudflats, swamps, streams and streams. With technological advances, the necessity of bedrock foundation is less important for structure. But is building in the historically swampy areas a good idea? Superstorm Sandy should have provided an answer. Areas that are low and were swamps, that historically flooded received a bulk of the damage. We knew it was coming. We knew where the water was going to go but the grey engineered systems gave us a false sense of security.

Which brings me to the importance of day-lighting streams. We need to learn to live with the environment. This is not to say that we should become victims of weather events and rely on a rhythm method of flood protection. What is needed is a balance of green and grey engineering that creates a more dynamic synthesis of urban and ecological form. Daylighting streams in urban areas is part of this. Exposure of the waterways not only creates a healthier ecosystem by promoting habitat it also serves an important pedagogic function.

Kids that play in streams will see the dynamism of fluid dynamics. They can experience spring surges and summer dry spells. Teachers and environmental educators can help them recognize the variety of birds, butterflies, fish and amphibians that migrate through, feed, breed and occupy the corridor. Waterways as corrIdors enhance habitat beyond their immediate area by creating connectivity with disparate patches of open space.

But fundamentally there is also an important functional reason to daylight urban streams. Green infrastructure provides an attractive and reasonably priced means for cleaning storm water runnoff and reducing the load on combined sewers. Plantings not only absorb water their evapo-transpiration helps cool the air reducing heat island effect. Blue green corridors help absorb pollutants and particulate matter in the air releasing clean oxygen. Day-lit streams can enhance wildlife habitat and improve the quality of life for urban dwellers as well.

Comparing structures in the natural environment with those from urban settings, a significant difference can be seen: nature works on principles of flexibility and resilience, a dynamic reaction and balance to any event, from a soft change to the unexpected disaster. We can learn a lot from this flexible and dynamic response of ecosystems in the design of urban settings.

Fast growing urban sprawl continues to cover the surface of the planet with asphalt and concrete. Instead of slowing down rainwater runoff, holding it back and avoiding concentrations, this type of development results in large quantities collecting at the same time and same place. These are the conditions for urban flooding. On the other hand urban streams often lack water in dry periods. As a result, temperatures rise and oxygen is low. In the absence of blue and green there is no filtration of air, no holding back of micro particles (wind-blown dispersal). Thus, there are higher dust concentrations which contribute to conditions that are unhealthy. Blue-Green Infrastructure (BGI), an approach to urban design that relies on natural elements (flora and water) which are deployed in strategic ways, can mitigate these conditions, creating natural corridors that are highways for biodiversity.

In 2006, the Public Utilities Board and the National Water Agency of Singapore started a program called ABC Waters—Active, Beautiful, and Clean—that aims to realize the full potential of an integrated BGI approach. By treating rainwater as a prime resource to fill up reservoirs and water bodies the ABC Waters’ program is a strategic initiative that works with the entire urban catchment of the island. Instead of getting water from far the city, urban development is the collecting surface and contributes to its water security.

One of the pilot projects, by far the largest, is the transformation of 3.2 km of the Kallang River in combination with 62 hectares of Bishan-Ang Mo Kio Park. This is classic BGI project with a strong social component—a vibrant urban river with natural elements counting over 3 million visitors per year. The benefits and improvement of this and other BGI projects are the objective of an ongoing research project by the Rambøll Foundation in partnership with Harvard, MIT, Zeppelin and the National University of Singapore.

There are many questions to be answered about the integration of BGI into cities. What functions and qualities must these spaces fulfill today and in the future? How can we create living systems that save natural resources, filter, clean and regulate water supply, balance temperature, produce good air, and increase natural habitats? What are the basic principles, processes and methods to integrate BGI in cities of today and in the future?

These questions must extend to the search for strategic policy making tools and good governance structures. Detailed knowledge about Blue-Green living systems, about materials and integrated technologies, have to be developed and experts must be called in during the early stages of the project, and importantly, be taken seriously. Urban landscape architecture should have a higher priority in a development and not be seen as byproduct.

BGI is not yet properly understood in its true function and value to a city and its inhabitants. It is the backbone for liveability, a repository of resources that balances and stabilizes life processes. We cannot easily measure, count and quantify the value of BGI to urban structures, not in the way that we might, say, hard forms of engineered infrastructure. BGI can never be a prefabricated décor that is countable, statically-determined and never-changing. It is a resilient living system.

And since these projects affect people, there must be public engagement and society building. To give hope to denser growing cities we have to create partnerships that balance the needs of people and the environment within urban landscapes in a more respectful way.

It seems we have all technology and knowledge available today; yet there is a lack of implementation. There is a discrepancy between what designers and engineers can create with what governments can activate in reality. We cannot afford this dilemma in the future.

In New York City, over the last centuries, hundreds of miles of streams have been piped and thousands of acres of wetlands have been filled. Most of the remaining streams and wetlands are degraded to some extend through physical and hydrologic alterations, invasive species, and pollutants. Many city dwellers have limited access to and interactions with streams and wetlands. Urban streams and wetlands restoration projects can help create that access and provide other social and environmental benefits by transforming the urban landscape. But these projects need to have clearly defined goals, be tied to integrated community and watershed plans in some way, and be maintained. The concept of stream daylighting offers an example of the benefits, and challenges, of one type of ecological restoration that might be easy to convey to the public and decision makers.

Daylighting most streams in NYC would involve removing roads, street trees, and even buildings, and re-locating a complex network of below ground utilities and infrastructure.  Sections of stream would need to pass in culverts or other structures under roads or railroad. The watershed is largely impervious, and the stream will likely be fed by piped stormwater runoff, resulting in a very different hydrologic regime than when the stream was last free flowingIllicit connections to buried stormwater infrastructure connected to the stream may also have an impact on water quality. In addition, likely space constraints limit how nature-like the stream channel can be when re-constructed. Ultimately, a developed urban watershed is likely to result in hydrologic and water quality conditions that will limit the abundance and diversity of biota a stream can support.

Given these complexities and limitations, there are situations in which other forms of green infrastructure bring more environmental benefit at lower cost than true stream daylighting.  For example, where there is too little space or it is too expensive to unearth an old stream course, the effect of a stream may be better achieved by building smaller, consecutive stormwater bio-retention systems that perform some of the same functions.  Or a system of stormwater capture or even greywater treatment and recycling, constructed as a wetland system, might be the most feasible and functional version of “daylighting.” In some cities, streams are piped in their entirety to a combined sewer system that flows to a wastewater treatment system. In such cases, the restoration of the stream flow to its natural receiving water body is the requisite action for water quality improvement. This might happen through daylighting, but could also be achieved using a pipe network, if space is unavailable, or if no mechanism in place for maintenance of the natural system.

But water quality enhancement or stormwater management is seldom the only, or even the primary, objectives of stream daylighting. Instead, these projects can provide natural beauty, increased biodiversity and habitat for insects and other fauna, shade and local cooling through evapotranspiration, opportunities for environmental education and stewardship, and interesting landscape features that draw visitors and even attract businesses. Measuring these social culture and ecological benefits is difficult, and usually very site specific. Daylighting, or new wetland construction projects, can be the best places to measure these benefits, because of the contrast they provide to the prior condition.

Stream and wetland restoration and other types of green infrastructure projects all need to be maintained and managed, after construction, in part because these systems are in urban environments with constant urban stressors. This sometimes requires establishing new maintenance and operation systems or partnerships, specific to the site and is usually difficult to fund. Ultimately both the construction and maintenance of daylighting and wetlands reconstruction is costly. Thus, these projects should help build the argument for why it is so important to protect existing aquatic systems in our cities.

Urban Wetland in Changwon—Bongam tidal flat in Masan Bay

In most countries with a marine coast, development-oriented national policies have led historically to the concentration of populations and industrial activities in areas adjacent to the ocean known as the coastal zone. For many developing countries, shipping, fishing, aquaculture, and coastal tourism are vitally important to their economies.

Not withstanding this importance, coastal resources are often developed with a land-oriented perspective that fails to consider the unique physical and ecological characteristics of the coast. During the last 40 years, the natural features of Masan Bay in Changwon have been dramatically modified by urban, industrial, and port developments, with its tidal wetlands having been reclaimed to accommodate the expansion of a large population and ever-growing industry. Thus, the problems of pollution have steadily increased and have become a matter of public concern.

The Masan Bay and its vicinity has long been the center of national economic growth of Korea since 1970. However the bay got drastically polluted due to rapid industrialization and urbanization. The pollutant load collected in Changwon’s watershed located in the area of Masan Bay is either delivered to wastewater treatment plant through sewer line or directly entered Masan Bay after passing through the Bongam tidal flat which serves as the natural purification system.

The Bongam tidal flat, as a brackish tidal flat of Masan Bay, is located in the center of Changwon city and is also situated at the inner-most of the estuary near the Changwon Industrial Complex Zone. This tidal flat was also under reclamation pressure and was long neglected as a small piece of tidal flat generally considered as a wasteland. However, as it is accessible to local residents and because of its ecological significance, it was finally protected at the suggestion of various NGOs and put into law by the government in 1999. Restoration efforts have been attempted at Bongam tidal flat since then. The Community Advisory Council for Masan Bay was established since 2005 as a legal organization for Masan Bay’s ecosystem recovery and total pollution load management (TPLM) system to manage the coastal environment of the Masan Bay as the 1st model case in Korea.

The Community Advisory Council established an eco-tour program which provides citizens an opportunity to witness the restoration of the ecosystem and the mudflat ecosystem service. To raise the public awareness of the importance of the ecosystem, this tidal flat was assigned as an official visit site during the 2008 COP10 Ramsar Convention held in Changwon.

Bongam tidal flat is home for a variety of salt marsh plants, migratory birds, crabs, otters, and benthos. With the combined efforts of the government and NGOs, the urban (Bongam) tidal flat in Masan Bay was designated as a national protected wetland area in December 2011 and has been managed as one of the successful wetland protected areas in Korea. The contamination level of sediments in the tidal flat was changed from heavily polluted to non-polluted level by the monitoring data between 2006 and 2012. The COD loading to the tidal flat of Bay mouth through three streams was gradually reduced from 2,690 kg/d in 2005 to 620 kg/d in 2012. This was made possible through a series of actions including sewer line repairs, expansion of wastewater treatment facilities, eco-stream development, clean-up activities and increased public awareness. The sediments and bio-species have been monitored from 1988 to the present. Citizen science monitoring has been directed by the governance.

It soon became clear that close collaboration of stakeholders was essential in achieving in the recovery and preservation of the bay ecosystem. Moreover, there have been various art works portraying the beauty of bay area. There are sculptures by well-known sculptor Moon Shin and a painting by an artist Choi Woon in which he portrays crabs in Bongam tidal flat as he saw in his youth.

The Bongam tidal flat as a restored urban wetland gives us back the ecological, cultural, and educational benefits and no pitfalls have been encountered. This kind of restored area as a place where citizens enjoy fishing, recreation, and education should be extended along the coast of Masan Bay. Decisions in urban policy could be made based on citizen’s awareness and interpretation of what the ecosystem services would be. Decision makers need to be more careful in habitat destruction, however, and we still want to change the way they make decisions. They do not put primary priorities on wetland benefits in urban planning.

What is the first thing that comes to mind when you think of your urban “east-west arterials” and “north-south arterials”? Most of us think of major streets. Yet most cities were strategically located on rivers that served as economic engines, sources of healthy food, and recreational gathering places. Our urban anchors are in our waterways.  In Portland, Oregon, our original “east-west arterial” is the Columbia River and our “north-south” thoroughfare is the Willamette River. In the face of climate change and 21st century resilience planning, healthy rivers are once again the armature of cities.

In Portland we are fortunate that the U.S. Endangered Species Act (ESA), and the Clean Water Act (CWA), passed before we had driven everything to extinction. The 15 ESA protected salmon and steelhead within the city limits drive water protection requirements such as temperature and metals. Motivated by strong regulations, Portlanders have discovered there are enormous ecological, economic and social benefits to restoring aquatic ecosystems in our urban core.

Rivers and streams piped and buried in the name of urbanization can no longer handle all of the stormwater, sanitary, and natural baseflows that run through them—frequently resulting in raw sewage floating in the remaining surface rivers, a problem dubbed by engineers as “combined sewer overflows,” or worse, backing up into people’s basements and businesses. Cities have few choices—build bigger pipes or separate the sanitary and bring the rivers and stormwater back to the surface where it is not confined to a fixed diameter pipe. Portland started down this latter path in the 1990s in response to regulations, but today many other cities are seeing the foresight in this approach as climate change brings more intense rainfalls more frequently. What we did in the name of clean water and endangered fish, many international cities are doing today in the name of resilience. Our “Tabor to the River” experience has also shown that treating stormwater at the surface can cost tens of millions of dollars less than an all-pipe solution. And our experience restoring natural floodplains can save governments and insurance companies thousands of dollars annually in flood damages.

Beyond the economic and infrastructure justifications for daylighting and restoring streams, wetlands and floodplains, there is also a remarkable unifying force a river can have on a neighborhood. Portland is nearly complete with a 7 year, 2.3 mile stream restoration at Crystal Springs. By removing the 80 year old concrete lining of the creek, upsizing nine culverts that were causing localized flooding and preventing fish passage, transforming a nearly three acre “duck pond” that contributed excessive heat and e-coli to the creek and replacing it with a wetland, and restoring riparian vegetation throughout the creek corridor, we have turned this veritable irrigation ditch into a community amenity that is drawing visitors from all over the city and beyond. Portland Parks took the opportunity to replace a decrepit playground with its flagship nature-based playground, complementing the stream and wetland restoration. The entire community, private businesses, federal, state and local governments, and many non-profits partnered in the endeavor, recognizing that public health and watershed health are intrinsically linked. Today, we have wild salmon spawning in downtown Portland, native waterfowl taking up residence, and an ecosystem restarting. A 4° C reduction in stream temperature and a significant reduction in the 100 year floodplain are helping us meet our regulatory requirements. Children have a reason to get outdoors and not become the nature deficit generation.

The only downside is that this blue-green approach isn’t possible everywhere. In Portland, planners, engineers, ecologists, and residents now agree we must make it the primary alternative, moving to another only if it is infeasible.

Urban wetlands restoration: cities out of the closet

An urban wetland is a condition in which a city is born, grows and develops. To restore is to reconcile something with its true natural identity

The city of Valdivia is located in the heart of the Valdivian Ecoregion: temperate rainforest, large rivers and a dense network of coastal wetlands. For thousands of years, the Mapuche communities that inhabit this territory have developed sustainable livelihoods within the limits of nature. In their symbolic universe, “cai cai vilu” is the snake of water, and fights constantly with the snake of earth, “txen txen vilu”. The balance of these forces results in a complex landscape, with active volcanoes, greats lakes, rivers, fjords and islands in permanent transformation.

The city of Valdivia, originally a European settlement, was born 450 years ago in this setting. For most of its life, the growth of the city was limited by nature. After surviving several earthquakes and floods, the city’s inhabitants decided to integrate a large belt of publicly-held wetlands into urban development because of their great importance for river navigation, military defense, supply of drinking water, and food production.

Tacon-angachillaHowever, in the last century, the situation has changed. These wetlands became a private property where their profitability prevailed over the common good. Changes in technology and economic conditions, coupled with the loss of social control, allowed the growth of the city beyond its limits. The filling and draining of wetlands through engineering has tried to hide the true nature of the city for decades.

Then, in 1960, Valdivia was the epicenter of the most intense earthquake and tsunami recorded in human history. Wetland soils do not meet the requirements of stability and security for buildings, especially in areas of high seismicity. Our ancestor, the water snake, returned to its domain and the urban wetlands surfaced again, like old wounds that never healed.

The history of Valdivia allows us to extract multiple lessons and to reinterpret the concept of limits to growth from a global approach to an urban local context, where wetlands mark some limits that urban growth can never overcome. Contrary to the prevailing view, where technology can solve all our problems, hiding urban wetlands through engineering is akin to trying to hide a natural condition.

In times of crisis, like the earthquake in Valdivia or Hurricane Katrina in New Orleans, nature forces us to “come out” and to accept the ecological reality. The accepting of the wetland as a natural condition forces us to establish a more mature and honest relationship with our planet. Cities can not hide their true identities forever; therefore, to restore wetlands is to reconcile with the past and to project into the future. But to restore wetlands is not only to recover the structure and dynamics of these natural ecosystems—it is also a means to restore the cultural, economic and political relations that allow wetlands to be managed as a common good.

We all know that to restore wetlands is a large and complex task. Although it is not easy to perform a cost / benefit balance of wetland restoration, and it can be an expensive activity, it is much better than to bear the cost of natural disasters caused by poor management. Wetlands are highly resilient when they stop being stressed, and can quickly recover their functionality, providing multiple benefits and ecosystem services for sustainable urban development. Restoring urban wetlands is a sign of maturity in the planning of cities, which recognizes their natural conditions and reconciles development with cities’ true identities.

Extinction of Experience: Does it Matter?

Art, Science, Action: Green Cities Re-imagined

Right after I graduated from Cornell, I took off for the North Cascades wilderness. First as a student and later an instructor for the National Outdoor Leadership School, I spent summers in Glacier Peak Wilderness Area, ice climbing out of crevasses, backpacking through Pacific Northwest old growth forests, and scaling ancient volcanoes. For me, this was true wilderness.

In my early 30s, I moved back to Ithaca, NY. Initially, I did not appreciate the rural upstate NY landscape—compared to the North Cascades, the wild spaces were tame and pockmarked with ugly houses. Years later, I have come to find solace in nearby nature. This time of year, I gaze up at ice-veiled waterfalls and ski along frozen creeks. Still, compared to the North Cascades, these are but slivers of nature among neighborhoods. At night, they are bathed in city light. Have I become victim to “extinction of experience?”

The lepidopterist Robert Pyle first introduced the term “extinction of experience” in 1975, writing:

“As cities and metastasizing suburbs forsake their natural diversity, and their citizens grow more removed from personal contact with nature, awareness and appreciation retreat. This breeds apathy toward environmental concerns and, inevitably, further degradation of the common habitat….So it goes, on and on, the extinction of experience sucking the life from the land, the intimacy from our connections… people who don’t know don’t care. What is the extinction of the condor to a child who has never known a wren?”

Ecopsychologist Peter Kahn describes a similar phenomenon, which he calls “environmental generational amnesia.” As each generation’s experience of “wildness” is diminished—as areas of intact wilderness are carved into smaller patches and eventually yards, and as children no longer gaze at stars in the night sky—humanity’s wildness “baseline” shifts. Although Kahn recognizes vacant lots as places to experience “wildness” in cities, he, similar to Tim Beatley in describing the nature pyramid, argues:

“Domestic, everyday, local nature… is … only half of what we need to flourish, as individuals and as a species. The other half that we need to keep alive—in our experiences and in our language—is the importance of wildness, of places that are large in scope, self-organizing, and unbounded, and autonomous and self-regulating systems, and of interactions that can be grand and awe inspiring and also frightening and difficult.”

For many living in cities, Kahn’s wildness—“the other half that we need to keep alive”—is unattainable. Are city dwellers simply out of luck—not able to flourish?

For me, the opportunity to traverse glaciers, summit peaks, and hear the trilling of the Swainson’s thrush reverberate amongst towering old-growth, was a peak experience—it enabled me to flourish. But 20 years after I left the Pacific Northwest to come back east, I had another experience that has also enabled me to flourish—this time in the Lower East Side of Manhattan.

Like my North Cascades experience, my Lower East Side experience was a nature experience—but it was embedded in human culture. It was my first visit to a community garden. There I saw older Bangladeshi immigrants who had transplanted their intercropping traditions—amaranth, pigeon peas, flowering coriander and marigolds—to raised beds in New York City. For me, the cultural aspects of this experience were more powerful than—yet still connected to—nature. The immigrants were creating a sense of community through connecting to nature—creating civic ecology practices to support people and nature. A community garden is not Tim Beatley’s idea of recreating unplanned ecological spaces in cities. Rather, community gardens represent the emergence of unplanned cultural spaces that connect to nature—in ways that enable the spirit to flourish.

Here is my dilemma. I know that even if my children were to go on a mountaineering expedition in the Glacier Peak Wilderness, their experience of wildness would be different than mine. They would experience human impacts—glaciers retreating, species invading—of which I was unaware. Although some may claim that my children’s experience would simply be different, to me, it would be diminished. But does this matter?

If our concern with extinction of experience is related to health, as Beatley’s nature pyramid suggests, then I am less worried. I believe that urban places, perhaps especially the chaotic, self-organized places represented by community gardens and civic ecology practices more broadly, create new experiences that enable us to flourish.

But if our concern, like Pyle’s, is about what we will want to conserve, then we may need to embrace an urban reality. People in the future may work passionately to save a different kind of nature in cities—one that celebrates human’s caring for nature and communities. And whose acts of caring offer their own richness of experience.

On The Nature of Cities

It Is Difficult to Take In the Glory of the Dandelion

Art, Science, Action: Green Cities Re-imagined

“It is difficult to take in all the glory of the Dandelion, as it is to take in a mountain, or a thunderstorm.”

Charles Burchfield (1893–1967) is legendary for his watercolor landscapes, painted near his Buffalo, NY, home. His paintings are typically about nature: swamps and forests and backyards that include plants and birds and insects and rays of light. They are full of shapes and living things. His late period pictures, especially, are intense and even hallucinatory. There was a remarkable exhibit of his work at the Whitney Museum in New York City a few summers ago.

He was also a great journalist and over his lifetime wrote over 10,000 pages in various handmade volumes. It was there, on 5 May 1963, that he wrote: “It is difficult to take in all the glory of the Dandelion, as it is to take in a mountain, or a thunderstorm.”

And so they are difficult to take in, both for their beauty and their complexity. How can you describe and assess them? Convey them to one who hasn’t seen? You finally stumble, awestruck, into saying that they are “beautiful”, or “majestic”, or just “amazing”. But as scientists and decision-makers we often have to describe and quantify such entities and then communicate the results in ways that aren’t hopelessly obscure. That are somehow specific. That is, we need to communicate a very complicated thing in a simple, essential, and, above all, useful way.

I often find myself at meetings of scientists who want their work used more broadly among policy-makers and practitioners. I often find myself in meetings with practitioners and city managers wondering how to get information they can use. More rarely these are the same meetings.

Disconnects often reside when the language turns out to be different. The rewards don’t exactly match. The information that is needed is at a different scale—time, space, detail—than the information that is on offer. The value systems don’t quite match.

Or sometimes what we’re trying to communicate about is amazing, like a Dandelion. Irreducible. We try to reduce it to something we can measure, comprehend, and communicate. But we don’t quite capture it. The discussion becomes a frustration of ill-matched assumptions.

What is that famous saying? It is in bold below, generally attributed to William Bruce Cameron in his 1963 “Informal Sociology: A Casual Introduction to Sociological Thinking”:

It would be nice if all of the data which sociologists require could be enumerated because then we could run them through IBM machines and draw charts as the economists do. However, not everything that can be counted counts, and not everything that counts can be counted. 

Not everything that counts can be counted, and not everything that can be counted counts.

And yet…

And yet, people who have to make real decisions about the design of cities and parks and plazas and buildings crave, even require clear bases for their decisions; they crave data and information that would suggest the right course of action. Elected officials too, crave some data to support a project that, in the end, may have to, often do, spend a lot of money and proceed on a hunch, on intelligent intuition.

Don’t get me wrong. Intelligent intuition is a powerful thing. It is that, plus values, which lead us to say:

That Dandelion is beautiful.

And so it is.

***

Such conundrums turn up in abundance when we talk about ecosystem services. Why have we been so interested in finding monetary equivalents to the value of biophysical ecosystem services? It is so we can make apples to apples comparisons about how to spend money and make cities work the way we need them to: for people, for Nature, for economies and even for beauty. How much rainwater does a tree pit collect and so keep too much water from entering a combined sewage system (CSS)? That captured water can prevent storms from overwhelming the system, leading to sewage being released untreated, in a Combined Sewage Overflow, or CSO event.  According to EPA and other studies CSO events can release 20-30% of annual urban waste into receiving waters. For me, in New York City, those “receiving waters” would be something more familiar: the Hudson and East Rivers, which make Manhattan an island.

Even preventing CSOs through nature-based solutions is embedded with some abstract values. It costs money. What is the value of a cleaner river next to my city? I don’t swim there. I’m not aware, exactly, of how clean it is. But the idea of a clean river motivates me. What is the value of that?

We, as a society, often make decisions based on complicated and often inscrutable calculus. We make them, effectively, on (hopefully) informed intuition.

***

I worked for a number of years on a project with the Bureau of Land Management in the USA, on a team to create “Rapid Ecoregional Assessments” of the Mojave and Central Basin & Range (Nevada) Ecoregions. These Ecoregions are vast and complex (the Central Basin covers most of Nevada), but an assessment was needed—a description of the status of the place and how it is changing—that was broad in scope but shallow in depth. The BLM needed a useful snapshot that would help them know what to do as they managed their lands in the face of development, ecological transformation, and climate change.

A core thing in such an assessment is to “roll up” small-scale measurements to make larger-scale observations and conclusions. We wanted to take a collection of observations about species and agents of change (water extraction, exotic species, climate change, renewable energy development…not all agents of change are bad) and make conclusions about multi-dimensional and emergent attributes like “ecological integrity”. BLM could then know how to best manage its land for the future.

Was that roll up true? It depended on the values embedded in what we choose to measure and how we interpreted the numbers. Stated that way, truth had no relevance other than the value system we imposed by measurements we emphasized.

Was it absolutely true? No. Did it work was an evaluation of a value system our teams agreed on as key? Yes. Did it work as a decision making tool? We’ll see.

***

Perhaps everything that counts can’t necessarily be counted, but still there are controversial decisions to be made, hard decisions in which there are winners and losers, that have to be decided on hard comparison, apple to apple, that can’t rely on the studied intuition of a savant.

Or can they?

We strive to be societies of laws and rules, societies that are fair and equitable. When we can’t measure that Dandelion, on what basis can we say it is more beautiful than the hawkweed? Than the rose? Than the chickadee. Than the housing development? How is that fair?

But ideas and choices can, in theory at least, be based on values that transcend dollar value. We can decide, as a society, that the Dandelion is not only more beautiful, but more valuable than the parking lot.

We can decide as societies what we value, how we build, what kind communities we make, what they should look like. What they shouldn’t look like. To do so we will need to have more conversations about values. About the kinds of places we want to live. About what kinds of money-things we are willing to forgo to have them. These kinds of conversations will have to take place in commissions and planning boards. They won’t—and can’t—always be about putting dollar values on things, but they do need to assign Value through dialog. All of us will need to participate.

Words like improvisation and imagination and intuition can sound awkward in the context of science and policy. Yet these are the very abilities that we need to be able to see past and beyond the details—this species is here, that process is there—to create and understand how a vast and majestic thing works and how it might change.

Perspective is another important word—a sense of what you value in the picture you are creating. The Dandelion seeds are close up in Burchfield’s picture. He values them. The sky is there too. You need to see the patterns and perspective and not only the details; the beating of the heart and not just the heart’s location in the chest.

How do you “take in” a complicated, multidimensional thing like a mountain? Or a park? Or a community garden? Or a city?

With an act of scientific and social imagination.

As summer changed to fall, Burchfield felt the same urge to imagination.

“All day on the gateway to September putting in the huge insect tree in the August part. For the first time in weeks I let myself go in improvisation and fantasy.”

Why Do People Use Parks and Plazas in Buenos Aires?

Art, Science, Action: Green Cities Re-imagined

Parks have been significant sources of open space in urban history, ranging from private, even sacred spaces to fully public spaces serving as central points of social interaction and recreation (Stanley et al. 2012). On any given day, many thousands of people spend several hours outdoors in their local park simply living their lives. In addition to the explicit ‘reasons’ why people visit parks (take children, walk, play, or practice some sport), they are also places for solitude, places to think or talk things out, or places designated for slowing the pace of life (Greenhalgh and Parsons 2004). What are the principal and most common reasons people use green and open spaces? Surely having data on their desires would be important input to key city management planning. We interviewed park and plaza visitors in Buenos Aires to find out what attracted them to such spaces.

Public green spaces across Latin America have traditionally been favourite meeting places for people from all walks of life and all ages because of their association with air, light and nature, as well as culture and multiculturalism. Today more than ever before, and in common with the rest of the world, these spaces cater to a wide range of needs and provide society with social, environmental and economic benefits (Faggi et al. 2015).

In Buenos Aires, as in many cities around the world, parks and plazas have been designed as sites of aesthetic reflection or for specific social practices following a “top-down” planning approach (Stanley et al. 2012). While parks are large and contain a multifaceted green infrastructure, plazas are open space framed by buildings on most sides and usually hard surfaced. Both can host a diversity of civic activities and tend to be multipurpose. In Buenos Aires, by the late nineteenth century, green spaces began to be relevant urban areas in social life. Large public parks arose under the influence of French and English landscaping models coinciding with the hygienist movement in its attempts to relieve the burden of urban living. These transformations in the urban matrix produced structural and functional changes in Latin American cities that gradually departed from their colonial past, with tiny dry plazas between blocks, to striking landscaped big parks playing a central role as places for social integration (Faggi and Ignatieva, 2009).

What is it that makes someone feel attracted to a park or a plaza? How can size and form of a green space influence how it is used?

Surveying users to explore public perceptions of parks and plazas

In Buenos Aires, we compared representative parks and plazas in the federal city by interviewing users to explore peoples’ perceptions of the spaces. We wanted to know what people thought about the quality of the green spaces and how they used them. Plazas are smaller neighbourhood green and open spaces (up to 1 hectare), which tend to serve only local residents. Parks are larger areas, more than 2 hectares, which people take pains to visit because of their scenic qualities and diverse potential for activities.

The most common reasons for using public parks and plazas. The data are from 232 interviews with people using the spaces. Each person was asked to provide their top three reasons for visiting the space.

Interviewees preferred parks for practicing sports (running, yoga, aerobics, riding a bike) and recreational activities, while they preferred plazas for relaxation, to walk or stroll, and for other psychological benefits. We found no differences between parks and plazas when assessed by benefits such as social interaction or the opportunity to breathe fresh air.

Our results show that parks and plazas are valued spaces, although many of the respondents also have daily access to outdoor space (back yards, terraces, balconies) in their homes. People have many reasons for visiting green spaces. Parents want somewhere to take children to play in spaces close to their homes (plazas), as well as more distant parks that are well equipped with games infrastructure such as swings and playgrounds. The majority of those using parks are not residents within the neighbourhood itself, but people who travel from elsewhere to make use of high-quality and safe green spaces. For the last 10 years in Buenos Aires, municipal authorities have set up a green spaces revitalization programme and established a multifaceted strategy to make the green spaces more attractive. These actions aim at guaranteeing good, easily accessible places for social interaction, for walk or sports, or simply to come close to nature. They also intend to promote a healthier life through the practice of sport and the prevention of illnesses. Outdoor gyms, which are freely available, have been set up in several parks in order to increase the number of people getting physically active. They contain high quality fitness equipment suitable for people of all ages. In addition, professional instructors give a wide range of aerobic and yoga classes and different recreational activities. These new activities have been added to the traditional existing ones such as street markets, music, and various shows.

Urban green spaces provide a full range of community benefits (physical, environmental, psychological and social), but some parks types appear differentially important in providing certain benefit types. To meet friends, experience an organized and entertaining scene, or to get out of the house to breath fresh air did not seem to be linked to the size of the green spaces, as these services were mentioned for both parks and plazas. On the contrary, we found that physical and recreational activities, which are place demanding, can best be set up in larger parks (physical activities in parks: 28%, in plazas: 8%).

Appreciating nature could also be linked to larger sizes of green spaces. In some countries, people may want to enjoy plants, flowers, and trees, and much is invested by city councils to satisfy these demands. We found that, in both cases, interviewees did not mention green infrastructure. It seems that in Buenos Aires, green spaces are perceived to be more useful for recreational and social services than as places to conserve or appreciate biodiversity. However, we believe that “appreciating nature” was masked by our concept of “relaxation”, which occupied an important place in the scale of benefits. Abundant literature has shown that to “see green” can reduce domestic violence, quicken healing times, reduce stress, bringing psychological benefits in individuals (Ulrich 1984, Kaplan and Kaplan 1989). As stated by Tidball (2012) “seeing green” (plant–people interactions) implications for human health and well-being are well documented.

Plazas, but not parks, were mentioned as ideal places for a relaxing walk, to read, or to rest (psychological benefits). This finding is in accordance with Nordh and Østby (2013), who found that in Oslo, small parks are best fit for relaxing and philosophizing, reading, or eating/drinking. Perhaps this is because plazas are calmer places than parks, and are preferable for experiencing an undisturbed peacefulness on one’s own, as there do not exist the multiple activities that are frequently offered in the parks, especially at weekends.

Incorporating our results into management of green spaces

Our findings show that size and the offer of activities/infrastructure in Buenos Aires play a role in how a green space is used and how different benefits are recognised and perceived.

As around the world, there are now many different pressures and conflicting demands on parks and green spaces, from environmental pressures to sports, leisure and general recreational uses. Similarly, it is common to find a wide range of interdisciplinary work which includes interdisciplinary professional expertise, from landscape designers, ecologists, foresters, grounds maintenance staff, to play workers and health workers, all wishing to adapt and use a green space for different purposes (Greenhalgh and Parsons 2004). A management plan that takes into account these needs and desires from the outset will best serve the city’s population.

Apples and Tomatoes: Comparing Community Gardens and Municipally Sponsored Urban Agriculture

Art, Science, Action: Green Cities Re-imagined

A review of Public Produce: Cultivating our Parks, Plazas, and Streets for Healthier Cities, by Darrin Nordahl. 2014. Island Press, Washington. ISBN: 9781610915496. 224 pages.

When Darrin Nordahl first published Public Produce: the New Urban Agriculture in 2009, most urban agriculture took place in community gardens, backyard gardens, and urban farms. Public ProduceSince then, local municipalities have developed numerous new programs for growing food in public places. In his updated Public Produce: Cultivating our Parks, Plazas, and Streets for Healthier Cities, Nordahl highlights some of these more recent stories of agriculture in cities. Nordahl begins writing along the same line as many other books on this subject: the first two chapters summarize statistics on food insecurity and our unsustainable, illness-inducing food system and contain obligatory references to the work of Michael Pollan. Public Produce stands out from the rest, however, in its focused plea for municipalities to consider planting edible crops at city halls, public parks, streets, and plazas. Geared towards decision-makers at the municipal level rather than urban agriculture practitioners, Public Produce is a call to action for rethinking landscaping and public space in an effort to solve larger issues of hunger and sustainability.

The most valuable sections of Nordahl’s book are the plentiful examples of successful municipally-driven urban agriculture and the various suggestions for maintenance of such efforts. Fruit orchards in public parks in Calgary, for example, offer lessons learned in picking the right varieties for the climate. The planner who planted vegetables outside of City Hall in Provo, Utah, may have inspired passersby to eat more vegetables. The story of an arborist in Davenport, Iowa—who planted publicly accessible fruit trees because, well, it was his job to plant and maintain public trees anyway—suggests that municipalities may already have the capacity to grow pick-your-own edibles.

One thing quickly becomes clear: Nordahl believes city government is a more effective provider of urban produce for the general public than community gardeners and urban farmers—themselves members of the general public—can ever hope to be. Nordahl makes an inconsistent case against grassroots community gardening, in some places acknowledging its important historic, present, and future role in urban food systems, and in others arguing just the opposite. Nordahl’s ambiguity stems from his disagreement with the misconception that community gardening will feed cities and that municipally-driven edibles in public places can feed cities.

In Chapter 3, he recounts the moment in New York City history when Mayor Rudy Giuliani tried to auction most of the city’s community gardens to private housing developers. Nordahl uses this story to argue that community gardens are too easily barricaded and bulldozed to serve as sites for growing publicly accessible produce. He might just as easily have made the case that municipal governments need to invest in preserving and protecting gardens as obvious locations for growing free and local food. Instead, he threw the baby out with the bathwater—or, in this case, the crops out with the compost. Nordahl believes suburban parks, parking lots, downtown plazas, streets, flood plains, and utility and transport easements are all better, more stable sites for growing food than a community garden. For this idea to work, municipalities will need to plant and cultivate enough edible crops that anyone can casually harvest, completely for free, as they walk by.

I would argue that this type of public produce has far less of a chance of actually building community than do community gardens, and also doesn’t necessarily ingrain food as part of the urban landscape. As Nordahl notes in Chapter 3, Calgary city officials learned that “orchards that are planted in parks without an associative community group don’t thrive like those planted in parks where there is already a large contingent of community gardeners”. A better approach might involve supporting existing gardening groups by providing more space nearby and more resources to plant orchards. With urban agriculture in the hands of city officials and not the community, who’s to say a new administration wouldn’t prefer a return to ornamental plants at some point in the future, such as the example Nordahl describes from the garden at City Hall in Baltimore?

Nordahl emphasizes the potential for alleviating hunger by growing food in cities. Yet none of his examples prove this point. Only City Fruit in Seattle, a group that coordinates and distributes fruit harvests from residents’ backyards, comes close. Yet City Fruit succeeds because of strong community organizing—not because of municipal programming. Once again, a municipality finds real success growing and distributing food in public spaces when a community group takes on the task. The Beacon Food Forest, also in Seattle, has potential due to its sheer size (seven acres), but at the time this book was published, the project had not yet been completed.

Two other examples of successful public produce recounted in the book actually have nothing to do with alleviating hunger. They are, however, viable examples of using publicly grown food to create revenue that can flow back into municipal coffers. In Chicago, apiaries on City Hall provide honey that is sold at the Chicago Cultural Center, the proceeds of which fund the Department of Community Affairs. At UC Davis in California, the University transformed campus olive trees from a nuisance to a source of revenue by producing locally-made olive oil, which funds the UC Davis Olive Center. This could be a great way to convince governments to take on planting edible perennials—but isn’t the point of such programming to make food more freely accessible? How can residents ask for fruit trees in public places without the need for government to harvest the yields and sell them back in order to fund the orchard’s maintenance? These examples disprove the argument Nordahl makes throughout the book—that food grown out in public should be freely accessible to all.

“What if community gardens were to make money?” Nordahl ponders, before discussing Detroit’s growing number of urban farms. Community gardeners are typically neighborhood residents working together to replace a vacant lot with green space, social areas, and/or edible plants. Urban farms, on the other hand, are typically managed by organizations that might grow food for a community, but aren’t usually as inclusive in their decision-making processes as a community garden. There is a grey area between the two, and many urban farms—especially in Detroit—consider themselves to be community farms in which the crops are grown and harvested by the community, often with a social justice and antiracism mission. Nevertheless, calling on community gardens to become urban farms that sell products changes the model of urban agriculture from one that freely provides food and community green spaces to a model that is profit-driven and/or mission-driven and often less focused on self-determination.

Other examples, including converting the ornamental landscape in front of city hall in Provo, Utah to a vegetable garden, were more symbolic than substantive in their impact. While the tiny garden in Provo yielded a surprising 1,200 pounds of produce over the course of a season, the yield was hardly enough to support the needs of hungry residents. Nordahl does admit this inadequacy in Chapter 4, where he explains that public produce can’t provide enough food to feed everybody all the time, but elsewhere he speculates that public produce will help ensure no one will ever go hungry. Which argument does he truly believe?

Nordahl’s case against community gardens as vehicles for alleviating hunger is especially troubling given that the cases he includes in the book suggest otherwise. He assumes that if you are too poor to buy food, you are also too poor to buy lumber, soil, trowels, seeds, and whatever else it takes to start a garden—so city officials should do the gardening for you. Yet on the ground, people with few resources start vibrant community gardens all the time; sometimes, these groups get a little extra help from agencies in supportive municipalities, but just as often they flourish with no external help whatsoever.

One of Nordah’s main critiques of community gardens is that the food they produce is often fenced off and unavailable to the general public—but what’s not mentioned in the book is that community gardeners are often growing produce as a survival strategy. In many cities on the East Coast and Midwest, neighbors build community gardens as a response to urban disinvestment and the blight of vacant lots. Gardeners aim to beautify the neighborhood, create safer blocks, and grow healthy food where healthy food is unaffordable or hard to come by. Gardeners in these cases are not wealthy people with time and money to spare, as Nordahl suggests. And because these gardeners might be relying on that relatively small amount of produce to keep food on the table, it’s no surprise they might not want to give it all away for free (although, amazingly, many do). In addition, there are plenty of examples of community gardens that garden communally and give anyone permission to take produce, not to mention the scores of community gardens that have both individual and communal plots.

Community gardens will never grow enough food to feed an entire city. Neither will parks, plazas, or other public green spaces. Yet every little bit helps. Why not support both?

Nordahl should include more examples of partnerships between municipalities and communities to grow food, as he does with City Fruit. Seattle’s Parks Department provides funding to the non-profit for their community steward program, which takes care of fruit trees in public parks. Gilman Gardens is almost a good second example: a community garden in a street median in Seattle. This garden lacked a water supply, and Nordahl makes a great case for cities to easily support gardening initiatives by simply providing water. If they can’t do that, however, Nordahl suggests moving the production to landscaping that is already irrigated. It is unclear in this example if he thinks the community will uproot and follow their garden to this new area or if municipal maintenance workers will take over growing the crops. Either way, this strategy would not really help the community and their food-growing efforts.

That Nordahl doesn’t seem to trust community-based urban agriculture efforts as much as he trusts municipally-sponsored initiatives detracts from the effectiveness of his call to action. Municipal support of community-based efforts could help urban agriculture grow and become a more widely adopted and secure land use. Public Produce is valuable for its detailed examples of urban agriculture that go beyond the familiar community garden, backyard garden, and urban farm, and provides numerous ideas for municipalities ready to take a more active approach to urban agriculture. These approaches do not have to be mutually exclusive, however, and Nordahl’s book would have been more productive had he embraced a diversity of possible tactics for cities aiming to feed themselves.
