Sustainable Consumption is a Myth

#BlackFriday at Best Buy, 12:01am (cc) Robert Stromberg @ Flickr.com

Continual growth and consumption is unsustainable. We’ve published many books on why the idea of “sustainable consumption” is impossible, but this post by Alison Singer at Worldwatch breaks it down simply and effectively.

Across the globe the concept of sustainable consumption is being touted as the way of the future, a change in lifestyle and values that promises “green growth”– economic growth that doesn’t hurt the environment. Though not without obstacles and controversy, this concept has been embraced by policymakers, consumers, and industry. The idea is that, by providing consumers with a choice of products reflecting their new environmental values, the market will self-regulate its way towards a more sustainable future, one in which supermarket shelves are lined with ecologically friendly products, and workers in developing countries are receiving fair wages for their labor. Eco-labeling, taxes on water and energy consumption, recycling incentives, education and communication campaigns, and advertising are examples of methods to promote sustainable consumption, all of which are endorsed by the OECD.

Foreword Friday: Big City Edition

This week, join New York City’s Chief Urban Designer, Alexandros Washburn, as he rides out Hurricane Sandy from his apartment in Red Hook, Brooklyn. In his new lavishly illustrated book, The Nature of Urban Design, Alexandros draws heavily on his experience within the New York City planning system while highlighting forward-thinking developments in cities around the world. He grounds his book in the realities of political and financial challenges that hasten or hinder even the most beautiful designs. By discussing projects like the High Line and the Harlem Children’s Zone as well as examples from Seoul to Singapore, he explores the nuances of the urban design process while emphasizing the importance of individuals with the drive to make a difference in their city.

“Mr. Washburn takes lay people on an illustrated and highly accessible tour of urban planning, from the High Line to the subway system, which, he explains, emits little more in greenhouse gases than the city’s streetlights.” —The New York Times

Contrasting Two Models of How Places Survive

Two September experiences reminded me of the strength and fragility of urban places, and the inherent ironies of surviving town forms. One such experience was here, at home, while preparing for a keynote address in New Hampshire scheduled for later this month. The other was on the road in southern France.

For the New Hampshire address, I have been asked to illustrate universal characteristics of urbanism to local government representatives, and the presentation is coming together well. The basic elements of the classic New England town is a convenient  model for today’s quest for compact, walkable urban areas. To existing residents of such towns, it’s a well-documented, “remember your past” message.

As new urbanist leader Elizabeth Plater-Zybeck summarized in an Atlantic article by Stage Stossell some 14 years ago:

“Many New England towns had rules stating that you couldn’t live more than a mile from the town green, in order to maintain some sense of community and control. Others controlled the way you could graze your animals on the land or how many animals you could own, in order not to deplete resources.”

But more challenging is addressing the second reminder, the one from France — what happens when the underpinnings for a town are taken away?

WHY RESTORE: LESSONS LEARNED BY BUDDING LANDSCAPE ARCHITECTS

Why Restore: Lessons Learned by Budding Architects guides us through an interdisciplinary approach to ecological restoration as seen through the eyes of Landscape Architecture graduate students at Temple University. As students of landscape architecture , we look to shape and manipulate the landscape. As growing restoration practitioners we seek to replenish and rework the past and return ecological systems to what they might have become. As scholars, specifically of Landscape Architecture and Ecological Restoration, we are learning to collaborate, understand and ultimately solve the problems within the public spaces of our world. Using the knowledge presented to us by John Munro who heads the ecological restoration department within our program, we explore various plant communities and ecosystems across the North Eastern United States. The culmination of our studies lead to the completion of a restoration project within our local community.

Our workshop specifically took us to Rickett’s Glen State Park in northern Pennsylvania, Pennypack Preserve in southern Pennsylvania, the Pine Barrens in New Jersey, and Cheltenham Township Park in Philadelphia. In these places we recorded reference plots, increasing the department’s collection of restoration resources as well as intimately learned native and non-native plant communities. On our own campus, in Ambler, Pennsylvania, we cleared out a square acre of invasive plants and constructed fascines from the woody material we removed from the site. The final project was to complete a streambank restoration project on Tannery Run Creek on our University’s campus; this stream has experienced an influx of stormwater runoff due to the decrease of open lands and increase of development in the region. Our class broke into smaller groups and installed check dams to restore vitality on the eroded banks of our local stream.

The result of this workshop, as well as our overall program curriculum, is an experiential and creative approach to hybridizing Landscape Architecture and Ecological Restoration. It has also encouraged us to think about the implications of ecological restoration and why it is so crucial for our present and future health and well-being. Through this video we examine the question “Why Restore?” and formulate an answer based on our reflections of the impact ecological restoration has at an individual level to the impact ecological restoration has at a societal level.

More Bugs, More Plants: A Crash Course on Biophilic Cities

We need nature even more these days. As more people live in cities, nature offers a potent remedy to many of the environmental, economic, and emotional challenges presented by urban living. To address this, a new approach to urbanism has arisen – a “biophilic” urbanism – based on the assumption that contact with nature and the natural world is absolutely essential to modern urban life.

Central to this vision for future cities is the concept of “biophilia” – popularized by Harvard biologist and entomologist E.O. Wilson. He defines biophilia as “the innately emotional affiliation of human beings to other living organisms.” He argues that humans carry with us our “ancient brains,” so it is no wonder that we are happier, more relaxed, and more productive in the presence of nature. The evidence is mounting, that we are likely to be more resilient and more creative when we live and work in the presence of nature. Some studies even show we are more likely to exhibit generosity when nature is near. As we examine the presence of plant and animal life in cities, it is becoming increasingly clear that nature is not optional but essential.

What is a Biophilic City?

A biophilic city is a city which successfully integrates nature into the urban landscape, from trees and parks, to vertical gardens and green rooftops. A city can become more biophilic through something as tiny as San Francisco’s parklets, or as major as Wellington, New Zealand’s enormous network of parks and marine life. A biophilic city nurtures and celebrates its biodiversity and wildness, from birds to wildflowers to the invertebrate life that inhabits the city.

Cities around the world are discovering creative ways to do this. Singapore, for instance, is working to integrate nature into denser, vertical urban environments, through a mix of regulations, subsidies, and research and development. Green walls and rooftops, an urban trails network – known as “park connectors”- impressively restored urban waterways, and schoolyard gardens are some of the ways Singapore has brought about its vision to be a “city in a garden.”

Why do we need biophilic cities?

Places like Mexico City – that invest in large green walls and rooftops gardens – reap the benefits of improved air quality and food security. Rio de Janeiro’s Tijuca forest – the world’s largest urban forest – has been essential is protecting the city’s water supply. In cities like Manila or Mumbai, protecting and restoring mangroves makes sense in terms of adaptation to storm surges and sea level rise. Making a city more biophilic will make it more resilient and sustainable.

These green elements will help us to shade and cool urban environments, to conserve water and energy, and to produce at least some of the food our growing planet is going to need.

Biophilic cities make our urban centers more resilient, and deliver emotional value for urban residents as well. Exposure to nature helps to make both cities and urban residents more resilient in the face of a host of likely pressures and shocks. My notion of a Biophilic city extends beyond the presence of nature to how residents engage with that nature – and how much we know and care about it. Urban biodiversity is necessary but not sufficient when creating a biophilic city. Biophilic cities need citizens who seek to enjoy, visit, and celebrate the nature found in the urban environment.

There are now many creative ideas for nudging urbanites in these directions, from summer camping in urban parks, to free kayaking on city rivers, to school-based initiatives that cultivate a love of nature in children at an early age. The innovative School of Ants – a citizen-science driven study of urban ant species- has produced a terrific urban guide to ants, a kind of flow chart to help children with the complex task of identifying different species. Experiments like these are instrumental in encouraging a love for biodiversity from a young age.

The Biophilic Cities Project

Our Biophilic Cities Project, based in the University of Virginia’s School of Architecture, has been underway for the past two years. With funding from the Washington DC-based Summit Foundation, and the Mitchell Foundation, we have been exploring the many creative ways in which cities integrate nature. By developing metrics for understanding urban nature, we can measure and document the many different ways cities provide connections to the natural world.

Much of this work has focused on exploring what a biophilic city is, or could be. We ask – what does it look like and feel like?  By assembling data and GIS layers for Biophilic cities around the globe, we attempt to understand how a city can protect and plan for nature in the urban landscape.

While we are already impressed with the variety of programs, projects, and planning efforts in cities around the world, there remain a number of important open questions:

How much and what kind of nature is needed in cities? What combination of these natural experiences will deliver the greatest health and psychological benefits? “What is the minimum daily requirement of nature?” we sometimes provocatively ask.  And what urban tools, techniques and strategies will be most effective at ensuring this nature exists in our urban future?

The next chapter in our work will involve expanding the community of planners, designers, public officials, and citizens interested in creating biophilic cities, as well as the geographical reach of the project. We will be convening our partner cities and launching this global biophilic cities network this coming October 17-20, at the University of Virginia.

A Conversation with Vancouver Deputy City Manager, Sadhu Johnston

Making Downtowns Liveable

Harold Henderson of Build a Better Burb interviewed author Ned Crankshaw, author of Creating Vibrant Public Spaces: Streetscape Design in Commercial and Historic Districts. He chairs the Department of Landscape Architecture at the University of Kentucky.

Henderson: If you could give a community  “dos” and three “don’ts” to make it more livable and attractive, what would they be?

Ned Crankshaw: DO center all hubs of activity as close to the center as possible. This includes schools, parks, other community facilities, and, of course, commercial enterprises. Use public buildings to support private enterprise by concentrating more people (customers).

DO develop a pedestrian walkability plan for the community. Use every project – whether it is a street improvement, property development, or a new public facility – to implement the plan and improve the quality of pedestrian spaces in streets.

DON’T design for visitors. Design for your own residents, and visitors will be taken care of in the process.

DON’T tear down buildings unless there is a specific funded plan to replace them with better building(s).

What are the best ways to add parking in a historic downtown? How can it be both hidden and convenient?

Crankshaw: Is there really a need for additional parking? If so, determine the destinations of those who park and locate new parking where it is convenient. “Convenient” places offer a pleasant walking path, a clear view of the destination, and a reasonable-length walk .

Parking shouldn’t be created by demolishing existing buildings, as a general rule. Investigate vacant spaces that may be suitable. Many of the best spaces may be behind buildings or in the interior of blocks and will likely cross multiple property lines.

What makes a place walkable, besides not having to cross four lanes of busy traffic?

Crankshaw: A walkable place provides supportive environments for pedestrians. That is much more than just a safe environment for pedestrians, which is an incredibly minimal threshold. Supportive pedestrian environments provide adequate path widths, buffers from vehicular traffic, visual variety and enjoyment, and shade. They should form a network that takes you places you want to go as directly as possible and with as much choice as possible.

Is it possible to overdo historic preservation?

Crankshaw: Preservation is ideological and mission-oriented. When there are competing values, it’s not always right. But because it is ideological, it always thinks it is right.

In many parts of the United States, the presence (or potential loss) of a town center with thriving businesses is an overriding concern. This is true in smaller cities and towns and in the older suburban communities of large cities. Preservationists need to support that goal even if it means backing off from their traditional fixation on details.

How closely should downtown signs be coordinated?

Crankshaw: Not at all. Towns should place some limits on size, appropriate to their locality, but business and building owners should be free to express themselves without being “coordinated” by someone else’s aesthetic sensibilities. If a town’s economy supports good businesses, those businesses will be smart enough to advertise with the right kinds of signs. People love the vibrant look of nearly cacophonous signs in historic photographs of downtowns and then want to reject freedom of expression in preserved downtowns. It doesn’t make sense.

Are “street trees” an oxymoron? How can they be done right?

Crankshaw: Street trees certainly are not an oxymoron in most residential neighborhoods, whose streets were designed with the idea that there would be trees. In many communities we are neglecting the need to maintain and replant trees in neighborhoods to make our streets more enjoyable.

In downtowns, street trees are a different matter. Trees have demonstrable value in traditional commercial areas. They screen parking areas, provide shade, shape space for pedestrians, and have other psychological and aesthetic values.

Completing Our Streets

In The Atlantic Cities, Lee Epstein writes about pedestrians hit by cars, the idea of complete streets, and where its principles need to go next. Here’s an excerpt:

“From about 1920-1970, streets and roads in America meant mostly one thing: moving cars and trucks quickly and safely – that is, “throughput.” All else was secondary, including pedestrian mobility, aesthetics, other vehicles (like bicycles), or how those roads and streets really “fit” or served a particular setting. Thirty or 40 years ago, interest in streets as integral parts of “place” increased, and road engineers and planners began the process of trying, at least, to humanize them. In the last decade or so, in addition to safety, functionality, and fit, issues of environmental, social and economic costs and benefits of particular urban transportation solutions have come to the fore. But even during most of this latter period, a road’s purpose was still chiefly perceived as making cars very happy indeed.

“In the early part of the last decade, transportation expert (and colleague and friend) Barbara McCann came up with the wonderfully clever concept of “Complete Streets,” which has become a very successful way for urban communities to re-envision, redesign, and improve their streets, and the ordinances which set the standards for those streets.”

Making 'Complete Streets' More Complete

McCann highlights how one day cyclists will no longer compete for the street.

Nature in Our Alleys

One key premise of our concept of Biophilic Cities is that nature is (and ought to be) all around us, nearby and readily accessible. We should not have to make a long trip to enjoy birds, trees and greenery. It should be in our neighborhoods.

Increasingly cities are finding creative ways to transform leftover spaces, pulling up pavement and impermeable sidewalks and installing verdant gardens, planting on rooftops and building facades.

Alleys represent one interesting place to insert or re-grow nature, and several cities have made impressive strides here.

On a recent trip to Montreal in May to attend and speak at the “Urban Biodiversity: A Value to Appreciate” conference, I was pleasantly surprised to discover the ways in which  this city’s alleys have been lovingly greened, and that the city has supported these neighborhood projects in many ways.

Josée Duplessis, who sits on the Montreal City Council, and whose portfolio includes parks and green spaces, drew me quick maps of her favorite green alleys – one off of St. Urbain, the other off of Rue du Square St-Louis. They were hidden gems, with doorways and openings not easy to find. Read more at BiophilicCities.org
