How Can Louisiana Build Back Smarter?

The flooding that hit Louisiana last week affected hundreds of thousands of people over 1,000 square miles. The intense storm claimed 13 lives, and some 30,000 needed to be rescued. Over 60,000 homes have been destroyed, and 100,000 have registered for Federal Emergency Management Agency (FEMA) assistance so far. According to the agency, the Louisiana flooding was a 500-year flood event, meaning there was just a 0.2 percent chance of this happening this year. However, this is the 8th 500-year flood event since May, 2015, which beg the questions: With climate change, are flood risk estimates now completely unreliable? And if super-storms are the new normal, what can communities do to build back smarter and make themselves more resilient to the next unexpected, disruptive event?

Wes Michaels, ASLA, a partner with Spackman, Mossop and Michaels, a Louisiana-based landscape architecture firm, said: “More rain fell in 4 days in Louisiana than the last 4 years in Los Angeles. A lot of places considered low-risk areas for flooding got a substantial amount of water, so it’s not just about people living in low-lying, flood-prone areas. These super-floods are unpredictable; they flood areas many people consider high and dry.”

Super-storms, while unpredictable, are becoming more common with global warming. As David Titley, a meteorology professor and the director of the Center for Solutions to Weather and Climate Risk at Penn State University, told Fast Company: “Warm air holds more water vapor than cold air, and we’re warming up both the air temperature and we’re warming up the oceans. Welcome to the future.”

The Washington Post editorial board in part blames FEMA’s out-of-date flood maps, “which determine who needs to buy government-sponsored flood insurance,” for the extensive damage. These maps “did not assess large portions of the area hit last week to be at high risk.” In reality, this means many of those hit by the storm will “not be able to call on an insurance policy.” The government only “presses people who live in so-called 100-year flood zones, areas that annually face a 1 percent chance of being flooded, to purchase government-backed flood insurance.”

According to Insurance Commissioner Jim Donelon, only 12 percent of homes in Baton Rouge and only 14 percent in Lafayette had flood insurance. As Elizabeth “Boo” Thomas, FASLA, President and CEO, Center for Planning Excellence in Baton Rouge, noted in an appeal posted to ASLA’s LAND, “though the floods affected people of all incomes, early indications show that a majority of victims are working-class or low-income individuals and families.” Many of those hit by the flooding couldn’t afford flood insurance, which is expensive, or didn’t expect they needed it. If a homeowner is insured, FEMA will pay out up to $250,000 in funds to rebuild. Thomas estimates the estimated value of the affected homes is around $5.7 billion.

FEMA only updates its maps each decade or so. But climate change and sprawl, which creates more impervious surfaces prone to flooding, are more rapidly changing the map of flood risk, particularly for coastal areas. Insurance premiums need to be tied to up-to-date flood risk, with higher premiums for higher risk zones.

According to Wired, communities now need “predictive flood maps: projections of flood risk based on modeling. Right now, pretty much all flood insurance comes from FEMA, which, again, updates its maps infrequently and also allows residents to comment and push back on the boundaries, effectively letting them determine their own flood risk. Insurance companies, which might have the capital to invest in models that incorporate climate change, have largely stayed out of the business since the 1920s—partly because it’s too risky, partly because government-subsidized rates are too low for private companies to compete with.”

But some firms, like Risk Management Solutions, are now developing their own flood risk modelling tools, because real-time modelling “could lead to better estimates of risk in certain places, which would allow companies to price policies accordingly and residents to really understand how risky their locations are. And as FEMA enacts some much-needed reforms (like phasing out government subsidies, for one), it may become easier for insurance companies to offer up flood policies, too.” Expanding the areas of people who are encouraged to buy into flood insurance could also help. Wired writes “if the insurance pool included people from 500-year floodplains, the risk would spread out more thinly,” reducing rates.

Beyond making the flood risk insurance system more responsive to a rapidly-changing climate, communities at higher risk of floods also need to rethink the status quo. Thomas believes that “smart, community-driven planning will play a lead role in rebuilding communities designed to thrive against a changing environmental context.”

And Michaels called for that planning effort to include a deeper analysis of the implications of car-based patterns of development. “As landscape architects, we need to be more involved in the design of infrastructure. Some of the unpredictability in flooding patterns comes from the storm itself, but some of it comes from how we design our interstates, roads, dams, bridges, canals and their related drainage systems. We need to think about how infrastructure fits into the larger landscape systems. Roads in particular, being long, linear systems, can drastically change how high intensity flood waters move across the landscape. There is an image in the news of a highway median wall backing up water on one side of the interstate near Walker, Louisiana. This wall may or may not have not caused flooding in other adjacent areas, but it certainly altered the flow of the water. These large infrastructural systems are pushing water around in ways that make the flooding less predictable, which makes planning for disasters more difficult. Our infrastructure needs to be designed to be porous to the flow of water (and species) across the landscape, and adaptable to the landscape at a much larger scale.”

He added that landscapes in high flood risk areas also need to be made more resilient: “Landscape architects should be leading the call to design our landscapes to be resilient to flood and disaster. The amount of energy, resources, and effort that will go into ‘re-landscaping’ Baton Rouge is staggering. Not to mention the carbon footprint of all the dying vegetation that must be cleaned up. We can no longer afford to see these disasters as outlying events, and go back to business as usual after the flood waters recede. We need to design landscapes that can be cleaned up with minimal effort after flooding and will adapt to changing soil and climactic conditions over the coming decades. We need to plant resilient perennials that can be chopped to the ground and come back to life. We need to plant trees that can resist flooding, and use soil technologies that allow trees to be healthy in the first place so they can survive stress.”

Michaels concluded: “I don’t think we can design systems that will prevent flooding in a 1,000 year storm. But we can think about the larger implications of our systems and how they will function in super storms at the landscape scale. And we can be smarter about how we design our landscapes and cities, so we can recover from these events more quickly and with less use of limited resources.”

A Universe of Interactive Art in Tokyo

In a leap for interactive art environments, Team Lab, a collaborative of Japanese artists, has put together a fascinating and bizarre collection of works in a 3,000-square-meter space in Tokyo. The pieces are truly responsive: visitors impact and shape the ever-changing works in real-time.

In the Dance of Koi and People – Infinity, visitors wade up to their calves through a shallow pool surrounded by mirrors, which creates the effect of being in an infinite space. As visitors walk through the water, underwater lights that mimic koi fish dart by.

According to the artists, the “trajectory of the koi is determined by the presence of people, and these trajectories trace lines on the surface of the water.” The even-more amazing part: “When the koi collide with people, they turn into flowers and scatter.”

The Dance of Koi and People- Infinity / Team Lab

This art work is derived by an algorithm in real time; it’s not a “pre-recorded animation nor on a loop.” It’s a work of continuous interaction and constant change.

In Wander Through the Crystal Universe, visitors interact with a giant pointillist sculpture in which “the particles of light are digitally controlled, and change based on the viewer’s interactivity with the work.” As visitors move, light shifts; as more visitors enter, light accumulates. Visitors can also use their smart phones to chose colors and shapes that will be included in the evolving piece.

In Floating in the Falling Universe of Flowers, visitors enable seasonal change. As visitors walk through, “flowers are born, they grow, bud, bloom, and, in time, the petals fall, and the flowers wither and die. The cycle of birth and death continues for perpetuity.” The piece also enables visitors to select butterflies with their smart phones and send them off into the surrounding “flower universe.”

And, lastly, Soft Black Hole, creates a dark space that plays with “the borders of floors, walls, and ceilings,” creating perhaps a startling version of a space you may find in a contemporary Korean spa. As visitors get into the space, their body weight shifts the environment, and so visitors impact the space of other visitors. “Your body changes the space, and the space changes the bodies of others.”

Building the Next Generation of National Park Advocates

The National Park Service (NPS) will celebrate its centennial on August 25. One hundred years after its creation, the U.S. national park system stands as the “best national park system in the world,” according to National Park Service (NPS) director Jonathan Jarvis, who spoke at the National Press Club in Washington, D.C. But he insisted that future success should not be taken for granted.

“Our centennial goal has been to create the next generation of visitors, supporters, and advocates for our national parks and our public lands,” Jarvis said. Failure to do so will result in losing the parks to “selfish interests,” or private development for short-term gain.

One way that Jarvis and the NPS have tried to create this next generation of park enthusiasts is by advertising the parks as part of America’s story.

“When I became director in 2009, we recognized that there were gaps in the American narrative as told by the national parks.” During Jarvis’ tenure, the NPS has taken into its stewardship 22 new sites, including several that speak to the contributions of minorities to America and America’s history of slavery and oppression. The latest place to be designated a national monument is The Stonewall Inn in Greenwich Village, New York City, considered the birthplace of the gay liberation movement.

With a backlog of $12 billion needed for park services and repairs, Jarvis was asked how the NPS considered taking on even more sites into its stewardship.

“In almost every case, we have minimized the actual amount of land or resources we need to take care of, and we have brought in philanthropic partners to assist with that. It does add to our overall responsibility, but I think we’ve been very judicious in ensuring it does not add significantly.”

No one can suggest that the park system has not been successful under Jarvis’ leadership. 2015 saw 312 million people visiting the park system. That is more than the visitors to Disney, the NFL, MLB, NBA, MLS, and NASCAR combined, according to Jarvis.

Still, support for the NPS has been steadily declining in congress. According to the Center for American Progress, members of Congress filed at least 44 bills or amendments that attempted to slash protections for parks and public lands in the last 36 months.

Jarvis said that he and his team are doing their best to partner with corporations and philanthropic bodies to offset certain costs. “The basic operation of a national park is the responsibility of appropriators. Philanthropy gives us that margin of excellence on top of that.”

Jarvis smiled as he waved off suggestions that sponsorship of parks on the part of private partners might lead to signage reading, “The Grand Canyon, brought to you by Exxon.”

“We have always had relations with corporate America. It was the railroads that built most of the major lodges. We are protecting these assets from branding and labeling.”

Asked where he sees the future of the NPS heading, Jarvis reiterated the importance of inspiring a new generation of conservationists and preservationists to “bring the concept of conservation back into their own communities. Many of the initiatives that we have launched, like the studies around the contributions of Latinos and women and Asian American Pacific Islanders, and LGBT community, will be carrying on into the next administration. I don’t see this ending.”

Summer Book Recommendations from Landscape Architects

The Book of Night Women
The Book of Night Women / Riverhead Books

It’s almost August, but there’s still plenty of time left to dive into some quality summer reading. We asked a few landscape architects to share books they’ve been enjoying. Check out their suggestions:

Diane Jones Allen, ASLA, principal at DesignJones, LLC

The Book of Night Women by Marlon James
“I have just finished reading The Book of Night Women this past 4th of July. This book is written by Marlon James, who won the 2015 Man Booker Prize for his book A Brief History of Seven Killings. The Book of Night Women is a beautiful and lyrically-painful narrative about the lives and landscape of slavery on a Jamaican sugar plantation. If you are passionate about Faulkner and Morrison, then you will relish this book.”

Gerdo Aquino, FASLA, firmwide CEO at SWA Group

Ghettoside by Jill Leovy

Ghettoside
Ghettoside / Spiegel & Grau

“A book that grew out of Los Angeles Times’ Jill Leovy’s reports on homicide and working the police beat from 2001 to 2012, Ghettoside takes the reader deep into the communities of south Los Angeles to understand why homicide rates are some of the highest in the country. Weaving together Los Angeles and U.S. history, perspectives from veteran LAPD detectives, scholars, and most importantly those living in Compton, Watts, and adjacent neighborhoods, Ghettoside provides a compelling piece that couldn’t be more timely and fiercely urgent as this country continues to face issues of race and violence, and the consequences of ignoring them.”

California by Kevin Starr
“Everything you wanted to know about California from a great historian. Starr gathers together everything that is most important, most fascinating, and most revealing about America’s 31st State.”

The Bathroom by Jean-Philippe Toussaint
“A playful and perplexing book that centers on a young Parisian researcher who lives inside his bathroom. As he sits in his tub meditating on existence, the people around him further enable his peculiar lifestyle, supporting his eccentric quest for immobility. But then a not-to-be missed opportunity arises and his stable world turns upside down.”

Shannon Nichol, FASLA, founding principal at Gustafson Guthrie Nichol

A State of Change: Forgotten Landscapes of California by Laura Cunningham

A State of Change / Heyday Books

“For the last twenty years, Laura Cunningham has been melding her scientific training – rigorously cataloguing species from her field work in California’s cities and roadsides – with her obvious artistic talent and intuition, painting fluent watercolors of the vanished places that she can now, naturally, picture in her mind. This book feels like her explorer-journal, each hard-earned page built up as she explores and documents a new landscape or vista found in a shockingly familiar, urbanized place that we thought we already knew.

This book is a modern-day reassurance that the age of exploration – and the age of the artist-naturalist – is not over. Perhaps, instead, our era, in which we separate science and art, facts and intuition, may be giving way to a more nuanced one that picks up where the explorer-naturalists left off.”

“The Collapse of Western Civilization is essential reading for anyone truly interested in sustainability and the global environment.”

Anne Whiston Spirn, FASLA, professor of landscape architecture and planning, MIT

Toward an Urban Ecology by Kate Orff, ASLA

The Time of the Force Majeure by Helen and Newton Harrison

Towards an Urban Ecology / The Monacelli Press

“Two brilliant new books are a call to action on urban ecology and climate change, with landscape as the principal medium. Kate Orff’s Toward an Urban Ecology is a presentation of ground-breaking projects by Scape, and the principles and strategies that underlie their success. In The Time of the Force Majeure, artists Newton and Helen Harrison describe their work on climate change, ecological design, and community engagement over the past five decades. The Harrisons design virtually every aspect of every project to ‘bring forth a new state of mind’ in themselves and their audience, and they employ ingenious strategies to accomplish this transformation. Human societies cannot successfully mitigate and adapt to the stresses of climate change without a new state of mind, and landscape architects and artists have an essential role to play. The Harrisons have been demonstrating this fact for more than forty years, Kate Orff and Scape more recently. Both books are required reading for landscape architects.”

The New Landscape Declaration: Visions for the Next 50 Years

Over the next 50 years, landscape architects must coordinate their actions globally to fight climate change, help communities adapt to a changing world, bring artful and sustainable parks and open spaces to every community rich or poor, preserve cultural landscape heritage, and sustain all forms of life on Earth. These were the central messages that came out the Landscape Architecture Foundation (LAF)‘s New Landscape Declaration: Summit on Landscape Architecture and the Future in Philadelphia, which was attended by over 700 landscape architects.

The speakers used declarations and short idea-packed talks, and attendees used cards, polls, and an interactive question and commenting app to provide input into a new declaration — a vision to guide the efforts of landscape architects to 2066.

As the 50th anniversary of the original declaration in 1966, many landscape architects looked back to see what has been achieved over the past 50 years. At the same time, through a series of bold statements, they created an ambitious global vision moving forward. As Barbara Deutsch, FASLA, president of LAF, believes: “We are now entering the age of landscape architecture.”

While not a comprehensive review of all the declarations, here are some highlights of the visions of what landscape architects must work to achieve over the next 50 years:

Landscape architects must address the “serious issues of air, water, food, and waste” in developing countries

Alpa Nawre, ASLA, assistant professor of landscape architecture, Kansas State University, called for landscape architects to focus their efforts on the developing world, where the bulk of the current population and most of the future population growth will occur. Today, of the 7.2 billion people on Earth, some 6 billion live in developing countries. There, some 100 million lack access to clean water. The global population is expected to reach 9.6 billion in coming decades, with 400 million added mostly to the cities of the global south. “To accommodate these billions, we must design better landscape systems for resource management.”

Gerdo Aquino, FASLA, CEO of the SWA Group, echoed that sentiment, arguing that “in the future, there will be much more stringent regulations on natural resources” as they become rarer and more valuable. Landscape architects will play a larger role in valuing and managing those resources.

Christophe Girot, chair of landscape architecture, Swiss Federal Institute of Technology (ETH) Zurich, similarly saw the need for “new topical landscapes” for the 9.6 billion who will inhabit the Earth. We must “react, think creatively, and find solutions.”

Landscape architects must improve upon urbanization-as-usual

Instead of pursuing idealized visions of parks that may result in “tidy little ornaments of green that make liberals feel good,” Chris Marcinkowski, associate professor at the University of Pennsylvania and partner at PORT Urbanism, said landscape architects must “work with the underlying systems of urbanization and adapt them,” softening them in an era when 1 billion people live in cities.

James Corner, ASLA, founder of James Corner Field Operations, pushed for accelerating urbanization in order to protect surrounding nature. “If you love nature, live in the city.” He called for landscape architects to “embed beauty and pleasure in cities” in the forms of parks and gardens, because we need to make it “so that people should want to live in cities.” Landscape architects must envision a denser urban world as well, and “shape the form of the future city.” His vision of the future city is a “garden city” that takes advantage of the “landscape imagination.” And Charles Waldheim, Hon. ASLA, chair of landscape architecture at Harvard University Graduate School of Design, and Henri Bava, founding partner, Agence TER, similarly made the case for a new “landscape-led urbanism” rooted in ecological processes.

David Gouverneur, associate professor at the University of Pennsylvania, called for applying novel approaches to the informal communities in which he works in Venezuela, where the conventional planning and design process fails. He proposed retrofitting these places through his “informal armature approach,” which can create both pathways and communal nodes but also areas of flexible growth that allows “locals to invade and occupy.” He argued that new forms of planning and design can better meet the needs of the hundreds of millions living in informal communities in the world.

And Kate Orff, ASLA, founder of SCAPE, explained how her community-centric approach “creates a scaffolding for meaningful participation that is an active generator of social life.” For her, it’s all about “linking the social to the ecological and scaling that up for communities.”

Carl Steinitz, Hon. ASLA, professor emeritus of landscape architecture and planning at the Harvard Graduate School of Design, also called for all landscape architects to get more active at the urban and regional scales. “That’s where society needs us the most.”

Landscape architects must create a future for wild nature

“The landscape has been broken into fragments. We need a more inclusive approach, a new philosophical relationship between humanity and nature,” said Feng Han, director, department of landscape studies, Tongji University in Shanghai. That new approach must be rooted in “just landscape planning and design.”

Randolph Hester Jr., FASLA, director, Center for Ecological Democracy, and professor emeritus, University of California, Berkeley, made a similar and compelling argument, saying that “justice and beauty must be found together in the landscape.” The landscape itself is a “community, with the ecological and cultural being indivisible.”

A central part of achieving that just landscape planning and design approach is to better respect the other 2.5 million known species on the planet, argued Nina-Marie Lister, Hon. ASLA, professor at Ryerson University. “We must think of the quality of being for them, too.” To protect their homes, landscape architects must lead the charge in “re-establishing the role of the wild.” E.O. Wilson, in his most recent book, Half Earth, calls for preserving half of the planet for the other species. “That kind of goal is a blunt instrument. Now we need to design what that looks like. We need a planetary strategy that connects remnant fragments. We can create a global mosaic that will be the foundation of a next wave of conservation.”

A key part of those mosaics will be designed sustainable landscapes, said Cornelia Hahn Oberlander, FASLA, who argued that “sustainability needs to be addressed in every landscape” moving forward. “We must keep every scrap of nature” by certifying projects with systems like SITES.

And in case anyone forgot the essential message: Laurie Olin, FASLA, founder of OLIN, argued that “everything comes from nature and is inspired by nature.”

Landscape architects must dramatically increase in number

Given landscape architects relatively small numbers — there are estimated to be less than 75,000 worldwide — Martha Fajardo, International ASLA, CEO, Grupo Verde, said each must “become ambassadors for the landscape,” speaking loudly wherever they go.

But Mario Schjetnan, FASLA, Mexico’s leading landscape architect, said that may not be enough and more numbers are needed. For example, while there are more than 150,000 architects in Mexico, there are only 1,000 landscape architects.

He said: “There are not enough landscape architects in the developing world. And we need a global perspective. The U.S. and Euro-centric perspective must change. More landscape architects from the developing world studying in the U.S. and Europe need to return to their countries and help.”

Landscape architects must diversify themselves fast

“Minorities are woefully underrepresented” in the field of landscape architecture, argued Gina Ford, ASLA, a partner at Sasaki. “The black and Hispanic populations in the U.S. are growing.” How can we address this? Ford called for the highest levels of academic and firm leadership to bring in and hire minorities. “It’s not about getting warm, fuzzy feelings; it’s about innovation. Diversity begets innovation. Diverse staff resonate with diverse clients. We must diversify to create a shared vision for the future.”

Landscape architects must get even more political

Patricia O’Donnell, FASLA, founder of Heritage Landscapes, who is active in UNESCO, ICOMOS, and other international organizations, said the first step is for landscape architects to “show up” and engage in political debates. Then, they must “collaborate to be relevant.” Working within these complex international fora, O’Donnell herself pushes for “connecting biological diversity with cultural diversity” and encouraging these organizations to value cultural landscapes. To be more relevant, she said, landscape architects should further align their efforts with the UN Sustainable Development Goals.

Kongjian Yu, FASLA, founder of Turenscape, may be the epitome of the political landscape architect. His work spans planning and design across mainland China, but he spends a good amount of his time and energy on persuading thousands of local mayors and senior governmental leaders alike on the value of “planning for ecological security.” He called for landscape architects to “think big — at the local, regional, and national scales” — and to influence decision-makers.

Martha Schwartz, FASLA, founder of Martha Schwartz Partners, who is an active advocate and commentator in the UK, where she now lives, threw down the gauntlet, calling for landscape architects to form a political wing that will urge policymakers to fund bold research into geo-engineering techniques that can stave off the planetary emergency caused by climate change. At the same time, “we need to start a political agenda for a Manhattan project to reduce carbon emissions.” Schwartz sees ASLA pushing for climate rescue over the next 50 years, helping us to “buy the time for a second chance to live in balance with the Earth.” For her and others, climate action is the platform for landscape architecture for the next five decades.

And Kelly Shannon, chair of landscape architecture at the University of Southern California, International ASLA, made the case for “changing the unsustainable status quo and inspiring new social movements.” Landscape architects must become “essential game changers.”

Landscape architects must better leverage green infrastructure to achieve broader goals 

Using their knowledge of systems, nature, and people, landscape architects must find new opportunities to regenerate poor communities that have been left out. Tim Duggan, ASLA, Phronesis, called for using green infrastructure as a wedge for creating opportunities. “In consent decree communities, green infrastructure can be leveraged to create wider urban regenerative processes.” Green infrastructure, as Duggan has shown, can become the catalyst for community development.

But to make this happen in New Orleans and Kansas City, he had to “lobby change at the decision-maker level and string together innovative financing mechanisms.” In other words, he had to wade into the broader economic and governmental systems to make change happen.

Landscape architects must keep design central to the human experience 

Charles Birnbaum, FASLA, founder of The Cultural Landscape Foundation (TCLF), said a “holistic view” was needed, and that landscape architects can’t foresake the important role of art and design in the experience of landscape architecture by focusing exclusively on ecological values. “We need to put the value of landscape architect on the level of the artist.” Harriet Pattison, FASLA, helped him make the point in this segment of her TCLF oral history project:

Blaine Merker, ASLA, Gehl Studio, argued for “making humanism physical and celebrating the human condition” through well-designed space for people. “Plazas and parks increase social connection. This leads to deep sustainability and happiness that reinforce each other.”

Landscape architects must generate new fields of research and design to stay relevant

A fascinating idea: what is on the margins today may be at the center tomorrow. Dirk Sijmons, co-founder, H+N+S Landscape Architects, argued for landscape architects to get more deeply involved in what may be a marginal area for them now: the transition to clean energy. He showed his work animating the energy flows of off-shore wind farms in the North Sea. “We must develop new centers for the discipline.”

Landscape architects educators must “revolutionize the landscape architecture education system” and become more pragmatic

Kongjian Yu also called for the educational system to teach the aesthetic value of ecology and sustainability. “We need deep forms rooted in ecology, not shallow forms. Nature is the bedrock.” Yu calls landscape architecture an “art of survival” that will become increasingly relevant as the world’s problems only multiply. “We need to teach how landscapes can fight flooding, fire, drought, and produce food. We need to generate pragmatic knowledge and basic survival skills to open up new horizons.”

Marc Treib, professor of architecture emeritus, University of California, Berkeley, added that “the sustainable is not antithetical to the beautiful. We can elevate the pragmatic to the level of poetry.”

While these bold ideas do push the landscape architecture agenda forward, what was missing from the LAF event was some critical discussions on how to better collaborate with scientists, ecologists, developers, architects, urban planners, and engineers on forging a common vision that can increase their collective impact in the halls of power; the coming explosion of aging populations; the health benefits of nature — and how the desire for better health could become a central driver of demand for landscape architecture; and sustainable transportation and the future of mobility. Hopefully, we’ll see more on these as LAF continues to hone its vision.

The New Landscape Declaration: Looking Back Over the Past 50 Years

At the Landscape Architecture Foundation (LAF)’s New Landscape Declaration: A Summit on Landscape Architecture and the Future, which met in Philadelphia last week, more than 700 landscape architects offered personal declarations and contributed their ideas, all in an effort to shape the 50-year follow-up to LAF’s original declaration of concern, published in 1966 amid massive political and social change and an era of environmental degradation in the United States.

Although the focus of the summit was on forging a new declaration and vision for the profession that can guide the efforts of landscape architects over the next five decades, there was also a call to “critically reflect on what landscape architecture has achieved over the last 50 years.”

Amid all the declarations and discussion, a few major themes came out of the reflections on what has shaped landscape architecture since 1966:

The American environmental crisis went global
From the original declaration: “A sense of crisis has brought us together.”

In his introductory remarks, LAF President Kona Gray, ASLA, was quick to note that in the 1966 declaration, “it was all about the American landscape.” The original declaration cites concerns that “Lake Erie is becoming septic, New York City is short of water, the Delaware River is infused with salt, the Potomac River with sewage and silt.” Kongjian Yu, FASLA, founder of Turenscape, noted that this 1966 description of the American environment was in sharp contrast to what Ian McHarg, influential landscape architect and one of the co-writers of the original declaration, simultaneously referred to as “oriental harmony” of the hydraulic civilizations of Asia. Yet 50 years later, Yu, along with Alpa Nawre, ASLA, assistant professor of landscape architecture at Kansas State University, were struck by similarities between 1950’s America and modern China and India today, where development has also led to environmental problems at an unprecedented scale.

In addition to the local crises of pollution, environmental degradation, and habitat loss that has run rampant in the developing world in the past few decades, new overarching global crises have emerged in the form of human-induced climate change and rapid population growth.

Landscape architects got political
From the original declaration: “We pledge our services. We seek help from those who share our concern.”

While the 1966 declaration does not directly address politics, according to keynote speaker Beth Meyer, FASLA, professor at the University of Virginia, Ian McHarg, author of the seminal book Design with Nature, and the other co-writers of the declaration were responding to not only the environmental crisis, but also the political opportunity introduced through the reforms of President Lyndon B. Johnson’s Great Society.

McHarg was influential in the development of first lady Lady Bird Johnson’s thinking on the value of beauty and nature in cities as well as the launch of the White House Conference on Natural Beauty in May, 1965. He later referred to first lady and environmental advocate Lady Bird Johnson “as his fan.”

Meyer argued then that his central role in creating the 1966 declaration may have been as much about environmental stewardship as a call for increased political influence by landscape architects. Just four years later McHarg would join thousands in Philadelphia for the first ever Earth Day event.

This political context set the stage for protest and advocacy by many other leading landscape architects over the past five decades. Just one example of this at the LAF summit is Martha Schwartz, FASLA, founder of Martha Schwartz Partners. In her declaration, Schwartz said that to respond to climate change, landscape architects must rekindle their political agency by being “online warriors” and rebuild the political wing of the profession that can “put forth a forceful agenda.” The sentiment was echoed by Kelly Shannon, chair of landscape architecture at the University of Southern California, International ASLA, who suggested that landscape architects must continue to “orient social movements and lead policy.”

People and parks returned to the city
From the original declaration: “Most urban Americans are being separated from visual and physical contact with nature in any form.”

At a time of rampant urban blight, the 1966 declaration made little reference to designing in cities. Fast forward 50 years and Blaine Merker, ASLA, director at Gehl Architects; James Corner, ASLA, founder of Field Operations; Henry Bava, partner at Agence Ter; Charles Waldheim, Hon. ASLA, chair of landscape architecture at Harvard University Graduate School of Design; and Kate Orff, ASLA, founder of SCAPE, among others, focused their declarations around celebrating and expanding landscape’s urban reemergence.

Whether it took the form or urban ecological planning, tactical urbanism, green infrastructure, or new parks and plazas, landscape architects have played a critical role in creating humane green public spaces for a new and increasingly urban generation. This effort has helped concentrate development, improve urban sustainability, and preserve the nature surrounding cities. As Corner championed: “if you love nature, live in a city.”

For others, landscape architecture’s return to the city allowed the discipline to grow beyond its 1966 definition as “applied natural sciences.” Christopher Marcincoski, associate professor at the University of Pennsylvania and partner at PORT Urbanism, argued that landscape architecture has effectively “softened the effect of urbanization,” at least in much of the developed world, but now must better anticipate the political, economic, social, and cultural forces behind urbanization in the areas left behind and the developing world.

For Tim Duggan, ASLA, these places are rich with opportunities. His declaration showed how his work not only over-layed environmental benefits, but also included the “overlaying of opportunities to find a catalytic but attainable scale” for financing and implementing regenerative infrastructure in under-served communities in Kansas City and New Orleans.

Landscape architects called for justice
From the original declaration: “Man is not free of nature’s demands.”

Perhaps one of the most resounding critiques of the 1966 declaration was its now dated emphasis on the conflict between man and nature. LAF president Kona Grey began by contrasting the six white male signees of the 1966 declaration with the 715 diverse attendees of the 2016 LAF summit. Throughout the summit, many speakers made the connection between the increased diversity of our profession and the increasingly diverse communities served by it.

There was Randy Hester, FASLA, a professor at University of California at Berkeley, who has long called for an ecological democracy. David Gouverneur, associate professor at the University of Pennsylvania, who showed his methods for working with informal settlements in the global south. And the work of Kate Orff, ASLA, founder of SCAPE, demonstrated that collaborative design can build both social and physical resilience simultaneously. These and numerous other efforts demonstrated a growing push toward environmental justice, combining landscape architects call to serve both the people and the places that sustain them.

In addition to addressing diversity in her talk entitled “Landscape Humanism,” Gina Ford, a principal at Sasaki, ASLA,  also joined others in realizing that humans are no longer “nature’s antagonist,” but rather are inseparable from nature.

Laurie Olin, FASLA, founder of OLIN, quoted the great 20th century thinker Buckminster Fuller, reminding attendees that “the opposite of natural is impossible.” Yet our inclusion in nature during what is being called the sixth great extinction, led Nina-Marie Lister, Hon. ASLA, professor at Ryerson University, to ask, “who in the Anthropocene will care for the wild things?”

Learning from the shortcomings of the 1966 declaration, the 2016 declaration must respond to a greater diversity of people, living creatures, and agendas in order for landscape architects to continue to “make our vital contribution.”

Landscape architecture expanded in scale and scope
From the original declaration: “…the landscape architect is uniquely rooted in the natural sciences.”

Delivering his declaration via a recorded video from Italy, Carl Steinitz, Hon. ASLA, professor emeritus of landscape architecture and planning at the Harvard Graduate School of Design, asserted that landscape architecture has grown to a “huge diversity of practices.” Steinitz charted how landscape architecture began as a multi-scalar practice, but has since ebbed and flowed between small, medium, and regional scales as predicted by the demands of each subsequent decade.

While Steinitz, Kelly Shannon, and Dirk Sijmons, co-founder,  H+N+S Landscape Architects, suggested a need to now revisit the regional scale so favored by McHarg and his colleagues, others assessed landscapes’ successes in prototyping smaller projects capable of global replication. The notion of landscape architecture as an expanded field was seen as both a pro and a con as some worried about being spread too thin, and others embraced the notion of landscape architect as infiltrator and instigator of public agencies and allied professions.

Ecological research was translated into design
From the original declaration: “The demand for better resource planning and design is expanding.”

While the global threat of climate change presents new, less visible challenges, many at the LAF Summit recognized that the 1966 Declaration’s call to action “to improve the American environment” had in many ways been answered. Having written, advocated for, and pioneered ecological landscape design projects, the impact of landscape architects has been transformational, many argued. As Mario Schjetnan, managing director of Grupo de Diseño Urbano, FASLA, noted, “U.S. cities have upgraded air quality, reduced soil and water pollution, and improved open space.”

In his declaration, Kongjian Yu, founder or Turenscape, FASLA, spoke of “50 years of experiments with fire, water, floods, and the landscape as living machine.” Noting new sustainability standards and guidelines such as LEED and the Sustainable Sites Initiative (SITES), “the change is amazing,” Yu exclaimed. He joined others in calling for the need to now “replicate and open new scales” through global practice.

Historic landscapes became more valuable 
From the original declaration: “…the landscape architect practices an historic art.”

Charles Birnbaum, FASLA, reminded LAF Summit attendees that 1966 was also the year that the Historic Preservation Act passed, and since 1998, Birnbaum, who is the president, CEO, and founder of The Cultural Landscape Foundation, has made enormous gains in documenting and preserving designed landscapes. For Birnbaum, placing cultural value on our existing landscape heritage is key to bolstering the contemporary contribution of landscape architects.

Complementing this perspective was Patricia O’Donnell, FASLA, founder of Heritage Landscapes, who for over 30 years has advocated for “culture-based sustainable development.” Referring to her projects with organizations such as UNESCO and their Historic Urban Landscape Initiative, O’Donnell’s work is exemplary of how the sustaining powers of culture and heritage create “a larger community (for landscape) to participate with.”

Landscape architects emerged as lead collaborators
From the original declaration: “There is no ‘single solution’ but groups of solutions carefully related one to another. There is no one-shot cure, nor single-purpose panacea, but the need for collaborative solutions.”

The 1966 declaration was ahead of its time in its vision of landscape architecture as a collaborative discipline. Many modern declarations reinforced that landscape architects have not only have benefited from these broad collaborations, but also have been increasingly leading teams on the great urban and infrastructural projects of our time.

While James Corner noted the role of his firm in leading large multidisciplinary projects, Kate Orff used her declaration to suggest landscape architecture firms are now the “collaborative glue… convening, organizing, and enabling others” through projects that serve as a “scaffolding for participation.” As LAF Executive Director Barbara Deutsch, FASLA, observed, increasingly you “can’t achieve sustainability without considering landscape.”

Landscape architects learned how to simplify and communicate complexity
From the original declaration: “Once they understand landscape capabilities—the ‘where’ and ‘why’ of environment, the determinants of change—they can then interpret the landscape correctly.”

Following the original declaration by only three years, Ian McHarg’s Design With Nature paved the way for the subsequent decades of research, scholarship, and communication by landscape architects to the broader public about the complexities of our ever changing built and natural environment.

From Anne Whiston Spirn’s The Granite Garden to Thomas Rainer and Claudia West’s Planting in a Post-Wild World, landscape architect’s played a critical role in deciphering environmental complexity. In his declaration, Dirk Sijmons, former chair of landscape architecture at TU Delft, showcased recent visualizations from the 2016 International Architectural Biennale, animating scenarios for offshore wind energy development in the Arctic.

For Sijmons, “research and design at a large landscape scale” is less about project implementation, and more about building the cultural influence and political will needed to take on the challenges of the Anthropocene – the age of man.

Landscape architects diversified, to some extent

In her opening, Barbara Deutsch noted that the field of landscape architecture still has a major diversity problem, but it’s far more diverse than it was in 1966, when the profession was mostly white and male. Now, membership in ASLA is 36 percent female and now only 68 percent of landscape architecture graduates are Caucasian. And landscape architecture is a global practice, with tens of thousands of diverse practitioners across the world. Still, there is much more work to be done in the future to attract African Americans and Latinos to the field in the U.S.

Duany: The Promise of Suburbia Has Been Betrayed

The transect / PlaceMakers

“The promise of suburbia — to live in nature amid the easy flow of cars — has been betrayed. Sprawl is not sustainable; its growth chokes on itself,” argued architect and urban planner Andrés Duany at the Congress for New Urbanism in Detroit.

Duany calls for using New Urbanism, an approach he and others have promoted for the past few decades, in order to “preserve nature.” New Urbanist developments can preserve nature because they can “make cities places people love to live in,” so they stop moving to the suburbs, contributing to sprawl. New Urbanist communities, he argues, are also inherently healthy and just, because there people “walk, so they don’t get fat,” and “you don’t need a car to get around.” In contrast, car-based communities are “un-just,” because the old can’t drive cars and the poor can’t afford them. Some 50 million Americans don’t have cars.

New Urbanism can also result in a more balanced relationship with nature. “In Europe, they had to integrate with nature. In contrast, in America, our relationship with the wilderness has been adversarial.” But Duany argues that if we use his model of the transect, which shows how cities can become denser as they move from untrammeled nature on the peripheries to dense urban cores, “we can bring nature into the city. Wildlife habitat can be assigned everywhere. The transect is also for bringing nature in.”

Sprawl, Duany argued, is rooted in a dendritic, inefficient, car-based system that must be overthrown with a new grid-based, walkable system. Furthermore, it’s one system or the other: “sprawl and new urbanism are incompatible and can’t be intermixed.”

Unfortunately, the “enemy” — sprawl — is backed by a range of “powerful” forces. There are “whole professions, like traffic engineers, who are vested in this system.” The solution is to provide these “administrators” with a new set of guidelines they can manage. “They just want to administer something. Let’s just change the manual, and then we can change what they administer.”

He envisions New Urbanist communities in which there are multiple choices that coincide with human nature, and the stages of life. These communities have a dense core that can sustain nightlife, which is critical for young people, “whose job it is to date and mate.” Once they’ve mated, they find a starter home, perhaps just out of the core. As they grown older and wealthier, they move closer to the periphery, where they have a larger house immersed in nature. Then, when they retire, they move back into a smaller apartment in the urban core.

Furthermore, human nature is to form hierarchies, and New Urbanist communities simply enable that basic tendency. “We can break up communities into wealthy mansions, mid-range, and low-range housing.” But for Duany, the key is they all live near each other in walkable communities, which enables a local economy, e.g. the maid and nanny live walking distance from the mansions. Duany is also all for allowing people to chose whether they want to live in a homogeneous or diverse community.

Duany said New Urbanists have enabled these kinds of neighborhoods by participating in writing the U.S. Housing and Urban Development (HUD)’s Hope VI standards, which enabled 270,000 units of affordable housing to be added in a subtle way to mixed-income communities. “We can integrate but keep the housing for the poor to 10-20 percent.”

He concluded that 30-60 percent of Americans want to live in New Urbanist developments where this kind of set-up is possible. “We just need to level the playing field to let the market operate.” In these communities, “life is better; people are more satisfied.”

F. Kaid Benfield, senior advisor to PlaceMakers, and author of the great book People Habitat: 25 Ways to Think About Greener, Healthier Cities, followed Duany, making many of the arguments outlined in his book. However, he further emphasized the need to better “integrate nature into the urban fabric,” perhaps going beyond what Duany and the New Urbanist’s transect offers. “We need nature inside cities, the kind that fits well.” For Benfield, that largely means mid-size (8 acres or less) and pocket parks, along with lots of trees, green complete streets, and all other forms of small-scale green infrastructure. As an example of a perfect-sized park, he pointed to Russell Square in London, “which is a great size — just small enough to reach but large enough to escape in.”

While landscape architects and designers may find some things to agree with here, what was left out of this discussion was the idea of cities as ecosystems. University of Virginia professor and author Tim Beatley, with his biophilic urbanism, shows that dense, walkable cities like Singapore and Wellington, New Zealand, can also be more biodiverse and create those rich connections to nature that sustain life for many species, even in cities.

Biophilic Cities Lead the Way to Urban Sustainability

“We need density but we also need connections to nature,” said University of Virginia professor Timothy Beatley, at an event at the University of the District of Columbia (UDC) to celebrate D.C.’s successful inclusion in the Biophilic Cities Network, a group of leading cities pushing for rich, nature-filled experiences in daily urban life.

Beatley launched the network only a few years ago, but it already seems to have taken off. Building on the impact of his important books, Green Urbanism, Biophilic Cities, and Blue Urbanism, the network is designed to improve knowledge-sharing among cities who seek to merge the built and natural environments. Leading environmental cities — such as Singapore; Portland; San Francisco; Wellington, New Zealand; and now, Washington, D.C. — have joined, and another 20-30 cities are now exploring signing on.

Beatley explained how biophilic cities forge deeper, more meaningful connections to nature, which in turn increases social connections and community resilience. He then highlighted some biophilic urban innovations:

Singapore (see video at top) is now putting “nature at the heart of its planning and design process.” Singapore’s official tagline used to be “garden city,” but now it’s “the city in a garden.” The idea, Beatley explained, is “not to visit a garden but to live in it; not to visit a park, but to live in it.” To realize this concept, Singapore has issued a landscape replacement policy that ensures any greenery removed through the process of developing a lot be replaced on the building eventually found there. In reality, though, developers, architects, and landscape architects have doubled or tripled the amount of original green footprint in buildings’ structures through the use of sky gardens. “There is now a competition among developers to see who can add more green.” The city has also built nearly 300 kilometers of park connectors to create deeper connections between parks and neighborhoods.

Melbourne, Australia, has pledged to double its tree canopy by 2040. “They are re-imagining the idea of the city in a forest. It’s a multi-scale investment in nature — from the rooftop to the bio-region and everywhere in between.” Individual trees are now being registered and made accessible via GIS maps. To further boost engagement, locals can also email love notes to a tree and the trees will write a note back.

A number of cities are forging deeper connections to urban wildlife, too. In Bangalore, there’s the Slender Loris project that engages citizen scientists in noctural journeys through the city to meet these shy creatures. Austin, Texas has gone completely batty, in a good way. Underneath Congress Bridge, millions of bat fly out at dusk during the warmer months to feed. Above and below the bridge, people gather to watch the amazing exoduses and sometime-murmurations. “There are now bat-watching dinner cruises.”

In St. Louis, there’s Milkweeds for Monarchs, which has resulted in 250 new butterfly gardens. San Francisco will soon mandate the use of bird-friendly building facades. And in Wellington, city officials are investing in predator-proof fencing in many areas with the goal of “bringing birdsong back.”

“Biophilic experiences are multi-sensory. Animal sounds can re-animate our cities. People want more nature; they want to hear birdsong in their neigborhoods,” said Beatley.

Stella Tarnay, co-founder of Biophilic DC, wants D.C. to become even more nature-filled. Her group will monitor new city projects to ensure they actually integrate greenery and boost biodiversity. For example, in Adams Morgan, plans are underway to remake the Marie Reed Learning Center with a set of green roofs and gardens, but it will be important to guarantee none of those great landscape plans get cut at the last minute for budgetary reasons.

Also in the works: building more support for the city’s wildlife action plan through expanded environmental education programs. As Maribeth DeLorenzo, deputy director of D.C.’s urban sustainability administration, explained, “there are now 270 species of birds in the district, 70 species of fish, 32 species of mammals, and hundreds of species of invertebrates.” But greater awareness is needed of these species — along with the biodiversity benefits of a clean and ecologically-healthy Anacostia River and the district goal of achieving a 40 percent tree canopy by 2032.

E.O. Wilson Calls for Preserving Half of the Earth

Half Earth / Liveright
Half Earth / Liveright

In his latest book, Half-Earth: Our Planet’s Fight for Life, famed biologist and author E.O. Wilson makes the case for both preserving and restoring half of the Earth, which he believes is possible if we set aside some of the richest places of biodiversity on land and in the oceans. These arks can protect up to 85 percent of all current life as the planet’s human population continues to grow from the current 7 billion to an expected maximum of 11 billion in coming decades. He believes humans have a moral obligation to be stewards of the millions of species that also call the planet home. And if we do not undertake such an ambitious conservation effort now, there could be potentially massive negative impacts for us, too. He reminds us that human survival is dependent on the survival of millions of other species, some of which are very tiny and not well understood.

Wilson is highly critical of our current approach to the environment. “We are still too greedy, shortsighted, and divided into warring tribes to make wise, long-term decisions. Much of the time we behave like a troop of apes quarreling over a fruit tree. As one consequence, we are changing the atmosphere and climate away from conditions best for our bodies and minds, making things a lot more difficult for our descendants.”

He seems shocked by humans’ collective thoughtlessness, which has severely affected other life forms as well. “We are unnecessarily destroying a large part of the rest of life. Imagine! Hundreds of millions of years in making, and we’re extinguishing Earth’s biodiversity as though species of the world are no better than weeds and kitchen vermin. Do we have no shame?”

Wilson concurs with other leading scientists that the planet is now facing its sixth great wave of extinction, largely thanks to us. While the conservation movement has essentially kept the patient — in this case, the world’s most critical ecosystems — on life support, the “heroic efforts” of both public and private-funded organizations haven’t been enough. Extinction rates are about 1,000 times higher than normal. Furthermore, according to a 2010 survey of two hundred experts on vertebrate land animals that analyzed the status of 25,000 known species, a fifth of these species are threatened with extinction and only a fifth have been stabilized due to conservation efforts. Wilson writes, “We might be inclined to say to the conservationists, ‘Congratulations. You have extended life, but not by much.'”

Oceanic ecosystems, which are still little understood, are even worse off, because vast swathes of the open seas aren’t managed by any one country. The result is a primary example of the “tragedy of the commons” in which “blue water, belonging to no one, is subject to no regulations whatsoever, save that established by international negotiation,” and, as a result, is plundered by all. “For generations, all marine waters, variously protected to some degree or not at all, have suffered over-harvesting of edible species. The downward spiral has been hastened by habitat destruction, spread of invasive species, pollution with toxins, and eutrophication from excess nutrient runoff.”

In Half-Earth, Wilson finally responds to those who see some glimmer of potential in the new Anthropocene, our current planetary epoch shaped by man. Their vision is of a planet made up of “novel ecosystems,” successfully managed to serve humans and perhaps some beneficial “nature,” but now degraded to its base functioning as “ecosystem services.” Their approach is a response to the failures of the conservation movement. It’s also rooted in their belief that “pristine nature no longer exists, and true wildernesses survive only as a figment of the imagination.”

Wilson says some practical ideas have come out of this “new conservation movement,” like managing nature parks and reserves in a way that helps meet the needs of people, too. However, he is scathing in his critique of the clique of writers, restoration ecologists, conservation biologists, and designers promoting this vision, accusing them of great ignorance of how ecosystems actually function. “It is been my impression that those most uncaring and prone to be dismissive of the wild lands and the magnificent biodiversity these lands still shelter are quite often the same people who had the least personal experience with either. I think it relevant to quote the great explorer-naturalist Alexander von Humboldt on this subject, as true in his time as it is in ours: ‘the most dangerous worldview is the worldview of those who have not viewed the world.'”

To save biodiversity, scientists, policymakers, planners, landscape architects and designers, and the general public must “understand how species interact with one another to form ecosystems.” Yet, Wilson says our current state of knowledge about ecology is “so poor as to limit this effort.”

In light of this general ignorance about ecology, he instead calls for protecting the “best places in the biosphere,” polling 18 international conservation experts to select those areas that can act as the few protected arks of life on earth. He writes that if these places can be protected and restored, “a great deal of Earth’s biodiversity can be saved.” In the U.S., these places include the redwood forests of California; the Longleaf pine savanna of the American South; and the Madrean pine-oak woodlands.

Furthermore, Wilson calls for the world’s scientists to accelerate efforts to map and make more easily accessible the Earth’s biodiversity. Some efforts are already underway. For example, multiple universities and research institutes have come together to create the Biodiversity Heritage Library, which will eventually hold more than 500 million records. There’s also the Encyclopedia of Life, a web site that describes some 1.4 million species, or more than 50 percent of known species. Other projects include the Global Biodiversity Information Facility, Map of Life, USA National Phenology Network, AntWiki, FishBase, and GenBank, which catalogues DNA sequences. Wilson sees a future where snippets of DNA sequences of mitochondrial genes can be typed into a search engine and the results would spit out likely species. To collect all this natural data, Wilson also calls for greater respect and support for the world’s naturalists — the professional or amateur collectors of specimens out in the wild.

Wilson concludes the book with his call to action: greater respect for the almost unfathomable complexity of our ecosystems, which he argues are even more complicated than the human brain. “If the approximately one billion years of evolution it took for the single-celled bacteria and archaea on our planet to evolve into more complex life forms were added, it is possible to sense how delicate our birthplace is, how complicated those parts of the ecosystem that shelter each species are, and how intricate and intertwined are the nonlinear interactions of the species.” Destroying this complexity in favor of short-term economic gains is a recipe for “self-inflicted disaster.”

Maximum diversity equals maximum level of stability. This is in fact the essence of resilience, Wilson reminds us. An Anthropecene in which a much more circumscribed designed nature is managed to deliver humans various ecosystem services is a “large and dangerous gamble.” Only restoration to natural ecosystems will bring back that complexity, even if baselines are hard to establish.

In today’s world of novel ecosystems, re-establishing baselines will be hard but also deeply rewarding work. The process involves “dealing with fascinating challenges deserving combined research in biodiversity, paleontology, and ecology. This will be one of the challenges met as parks and reserves are made centers of research and education around the world.”

Coupled with protecting and restoring half of the Earth, Wilson calls for higher-intensity and more sustainable development, which he believes is increasingly possible. Given our current constraints and the expected population boom, “the pathway of economic evolution will be set by growth that is increasingly intensive and less extensive.” And what will be the root of this new pattern of sustainable growth? Wilson believes it will be “contained in the linkages between biology, nanotechnology, and robotics.” Our planet’s rich biodiversity together with ever-advancing human technology will be the foundations of future growth and prosperity.

Has Landscape Architecture Failed?

anthropocene
Welcome to the Anthropocene / The Topograph

“A sense of crisis has brought us together. What is merely offensive or disturbing today threatens life itself tomorrow. We are concerned over misuse of the environment and development which has lost all contact with the basic processes of nature… A key to solving the environmental crisis comes from the field of landscape architecture, a profession dealing with the interdependence of environmental processes” — I. McHarg, C. Miller, G. Clay, C. Hammond, G. Patton, and J. Simonds. 1966. A Declaration of Concern.

In 1966, Campbell Miller, Grady Clay, Ian McHarg, Charles Hammond, George Patton, and John Simonds marched to the steps of Independence Hall in Philadelphia and declared that an age of environmental crisis was upon us and that the profession of landscape architecture was a key to solving it. Their Declaration of Concern launched, and to this day underpins the workings of the Landscape Architecture Foundation (LAF), now headquartered in Washington. To mark its 50th anniversary, the LAF will hold a summit at the University of Pennsylvania involving over 60 leading landscape architects from around the world. Delegates are being asked to deliver new declarations (manifestos if you will) about the profession’s future. Drawing upon these statements, the LAF Board will then redraft the original 1966 Declaration of Concern so that it serves to guide the profession into the 21st century.

On one level, redrafting the declaration is relatively straightforward: it would simply need to stress the twinned global phenomena of climate change and global urbanization — issues which were less well understood in 1966. On another level however, the redrafting of the declaration is profoundly complicated, because if it is to be taken seriously then a prerequisite to doing so is to ask why, after 50 years of asserting landscape architecture as “a key” to “solving the environmental crisis” does that crisis continue largely unabated? Seen in this light the declaration can be read as an admission of failure. Consequently, we must ask if McHarg and his colleagues were justified in placing such a tremendous responsibility on the shoulders of landscape architects why we have we failed so spectacularly to live up to their challenge?

The immediate response is to discredit the question; for surely the so-called environmental crisis is too general and enormous for any single profession to “solve” and then be measured against. The environmental crisis is the by-product of the ways in which the industrial revolution (modernity) has spread globally, beginning with the Industrial Revolution in the 18th century and continuing on as capitalism exploits resources for profit and growing populations work to free themselves from poverty. This, arguably, is completely out of landscape architecture’s — or for that matter any other profession’s — control.

Be that as it may, many landscape architects subscribe to McHarg’s assertion — made repeatedly in his manifesto Design with Nature which soon followed the Declaration — that landscape architects are “stewards of the earth.” If that is so then they have a prima-facie responsibility to answer for the continued denudation of the planet since 1966. Even if we reign in the question of failure to something more tangible than the entire environment — say just land-use in North America — then landscape architecture still appears to have largely failed in mitigating the most basic elements and causal forces of environmental degradation. In fact, it is hard to think of any environmental topic which landscape architecture could claim to have substantively improved over the last 50 years.

In our defense, we might argue that landscape architecture is a very young and very small profession and an even smaller academy. We can also protest, as many do, that other, more established disciplines — such as engineering and architecture — have restrained our rise to environmental leadership. We can argue that the status quo of political decision-making makes it impossible for us to meaningfully scale up our operations and work in the territory where our services are needed most. These justifications (or excuses) all contain aspects of the truth but here, by way of self-reflection on the occasion of the 50th anniversary of the original Declaration of Concern, we inquire more fundamentally into the evolution of the profession’s theoretical basis over its life time. Via this route we will return critically to the original declaration and argue that landscape architecture over the last 50 years is less a story of abject failure and more one of a discipline taking the time that has been needed to prepare for a more significant role in this, the twenty-first century.

The proliferation of theory and practice that emerged in response to McHarg’s ecological method in the latter half of the twentieth century can be organized through the archetypal paradigms of knowledge production; that is, through the competing epistemologies of positivism and constructivism. Positivism — the notion that objectivity is possible, that knowledge is constructed through empirical deduction, and that such deduction could lead to generalizable Truths – constitutes the knowledge paradigm within which McHarg’s ecological method evolved. For landscape architects, this meant that “there was a design for the earth, which made it for every form of life that has existed, does now exist, and all imaginable forms in the future” and that an intervention was “right when it [tended] to preserve the integrity, stability, and beauty of the biotic community.” This form of landscape positivism evolved into the contemporary forms of thought and action known as landscape performance, in which the ecological function of landscapes is measured, optimized, and even monetized; urban metabolism, in which broader urban systems are conceived as systems of stocks and flows to be measured and stream-lined; green infrastructure, in which landscapes large and small are designed to deliver a suite of ecosystem services; and to a lesser degree urban ecology, in which the relationship between social and natural systems form a more descriptive than prescriptive field of study. Put another way, landscape positivists argue that the solution is “out there” — finding it is simply a matter of empirical study and that relative equilibrium between natural and cultural systems is the aim.

Alternatively, Constructivism — the philosophy premised upon the notion that objectivity is a mirage, that knowledge is socially and inductively constructed, and that such inductions have little relevance outside of a very specific context — constitutes the knowledge paradigm within which reactions to McHarg’s positivism emerged. By the 1980’s in the “deconstructionist” phase of post-modernity, designers began to question McHarg’s prescriptive method, asking: Design with which nature exactly and according to whose values? Simultaneously, in practice the profession became predominantly involved in the design production of public, urban space; denatured places where McHargian land suitability analysis has only limited, if any applicability. In such places, phenomenological theories such as genius loci as well as attention to human behavior, aesthetics, and innovative construction techniques were found to be more inspiring and more useful. During the 1980’s the sublime art work which emanated from a generation of so called land artists was also brought to landscape architecture’s attention, reminding us of the historical depth and poetic potential of our medium.

In this vein in 1997, James Corner, ASLA, launched a critique that the “continual emphasis upon rational prowess — often at the exclusion of phenomenological wonderment, doubt, and humility — fails to recognize the very minor degree to which the combined landscape architectural constructions around the world have affected the global environment.” He argued that landscape architectural theory ought “…to find its basis less in prescriptive methodology and formulaic technique than in the realm of perception, phenomenology, and the cultural imagination.” This is to say that the staggering complexity of social-ecological systems and the inherent subjectivity of creative perception rendered McHarg’s notion of design as evolutionary fitness moot; positioning the designer as more of an artful interpreter than a landscape scientist.

Corner’s remarks echoed statements made a few years earlier by McHarg’s nominal antithesis, the consummate landscape architect Peter Walker, FASLA. Responding to allegations of environmental disinterest in his work, in 1995 Walker expressed regret that “… we’ve been held up by our fellows as being somehow culpable, but actually we’re a very small part of this whole problem.” He pointed out that with their “parks” landscape architects only impact about 0.02 per cent of the earth’s surface. Walker seems however to have missed the point: for whereas he used the profession’s puny territorial impact to absolve it of any significant environmental responsibility, from the perspective of the LAF’s founding fathers he just provided the statistical confirmation of its abnegation. Indeed, landscape architecture can not ignore the fact that in the same time that it has produced designs for Walker’s 0.02 per cent of the world’s surface, the global conservation community under the auspices of the International Union for the Conservation of Nature (IUCN) has by now legally secured an extraordinary 15.3 per cent of the planet as protected areas.

This raises the crucial question of landscape architecture’s professional identity and its scope: for if we follow Walker’s delineation that landscape architecture is in reality a profession more or less limited to the production of small, rarefied sites such as gardens, parks, and plazas then landscape architecture is – as its name suggests – most akin to the high design discipline of architecture, not planning or environmental science. For Walker landscape architecture is a public art and as such the environmental crisis is not its yardstick. As such we have not failed at all. On the contrary, over the last 50 years we can see that landscape architecture’s contribution to the subject of designing public space and creating ‘a sense of place’ in the wake of modernism has been a story of great success. In much of the the post-industrial, developed world, the transformation of the public realm into attractive, inclusive, and multifunctional places by landscape architects has been perhaps the most salient feature of post-modern urbanism. The problem remains however that this work is materially insignificant when compared to the reality of the “crisis” identified in the LAF’s original Declaration of Concern.

To try and broach this troubling discrepancy, what McHarg and later the landscape urbanists realized was that if post-modern landscape architecture was ever to transcend its history and be more than the design of gardens, parks, and plazas in locations predetermined by others, then the profession needed to “jump the garden fence” and somehow take on the city as a whole. In the case of McHarg, following in the lineage of Patrick Geddes and Lewis Mumford, this meant zooming out and placing the city in its regional context. This in turn inspired his methodological veneration of large-scale landscape systems as the ideal determinants of urban form.

Recoiling from McHarg’s positivism and New Urbanism’s reactionary, neotraditional aesthetics, in the early twenty first century landscape urbanists began to reconceive of previously stable notions of the city, nature, and landscape. Firstly, that thing called “the city” as a bastion of culture opposed to nature was conceptualized reinterpreted as a ubiquitous and hybridized combination of both; a new condition Neil Brenner labelled as “planetary urbanism.” Secondly, landscape urbanists found themselves mainly working in brownfield situations where “the environment” or “nature” had to be re-invented, not simply protected. Thirdly, landscape urbanists, along with everyone else were enveloped by neo-liberal economic restructuring, against which state sponsored large-scale (master) planning, at least in North America, was increasingly ineffectual.

So, whereas McHarg had zoomed out so as to control and direct the city in terms of its bioregion, landscape urbanists, for better or worse, realized they had to “get inside” the logistics of both shrinking and sprawling cities if ever they were to harness and redirect those forces toward more ecologically and socially just ends. Put simply, if they were to do more than just design post industrial parks and the usual repertoire of small public commissions, landscape urbanists had to also become urban designers and urban planners. It is no mistake then that Waldheim has, for the last decade or so, set about constructing a lineage of landscape architecture (via Olmsted, Wright, Hilberseimer, Branzi, Frampton and Koolhaas), which champions landscape architects as “the urbanists of our age.”

Substantiating this big claim has however proven difficult for the landscape urbanists: for not only have other disciplines not so easily given over the keys to the city, but landscape urbanism’s own adherents have been largely unable to substantiate the movement’s urban design aspirations with built work. To date, landscape urbanism has not been convincingly applied to at least three major forms of contemporary urbanization; mega-regional decentralization, suburban and peri-urban sprawl, and exploding informal settlement patterns in the developing world. This is not to say that the theory is flawed, on the contrary landscape urbanism is well suited to these challenges, but it seems hard to sustain the argument that  landscape architects are the urbanists of the age when they have so little to do with its major twenty first century characteristics.

In any event, hypothetically the question becomes what sort of city would landscape urbanists create if they could and in what way will it fulfill the environmental mandate of the original Declaration of Concern? The predictable answer is of course that they will create a green and “sustainable” city. Indeed, for much of the life of the Declaration of Concern, and especially since the Brundtland Report of 1987 “sustainability” has been a cure-all expression for everything the environmental crisis entails. In this sense, sustainability operates as a form of contemporary utopianism, literally a utopos meaning a good place, which is no place. Along these lines we argue that the sustainable city is an impossibility. Why? Because it is predicated on a stable-state view of the world.

The world view that idealizes equilibrium, harmony, and stability has roots in early twentieth century models of ecosystems, where it was thought that if left to their own devices natural systems tend inexorably toward stable climax states via the process of succession. During the era in which McHarg and the LAF envisioned such a harmonious relationship between humans and nature, mainstream ecological thought believed that systems could and should be stable if only we could remove human disturbance. But the science of ecology in the last 50 years has evolved away from the notion of stability and towards one of indeterminacy and resilience. Now, all of the ecological and physical sciences tell us that nature is chaotic, something we can only partially predict. If this is true, then how could humanity ever expect to achieve a McHargian balance with nature? Understood as a perfect end-state, sustainability is what systems theorists such as Donella Meadows describe as the “seventh archetype of systemic failure”: seeking the wrong goal. In other words, it is not that landscape architecture has failed to bring about sustainability — it is that sustainability is the wrong model!

In the wake of sudden chaotic events such as stock-market crashes, earthquakes, and 100-year storm events resilience theory has emerged as a more realistic theory of environmental and cultural change. Unlike the teleology of sustainability, resilience theory stresses adaptation to constant change and the ability to cope within a certain range, with that change. One of the most attractive attributes of resiliency as a new design paradigm is that it also operates in full-recognition of its short-comings. It is also organized around the idea of coping capacity — or the ability of cities, people, and ecosystems to cope, persist, and co-evolve with change and disturbance. Rather than working deductively — as sustainable development principles might — to superimpose an image of “good” upon a place and then work to reshape that place in a preferred image, resilience theory works from the local asset base outwards. For some this could be construed as sustainability without hope, a dystopia where the best we can do is calculate risk, but in its incipient stages as a theory of urbanism we prefer to think of it as design now getting closer to the way the world really works.

Considering our historical moment one is reminded of the incredible optimism with which the moderns announced theirs. In 1920 the great architect Le Corbusier launched his journal L’esprit nouvea with the declaration: “There is a new spirit: it is a spirit of construction and synthesis guided by a clear conception … A great epoch has begun.” A mere 46 years later a small group of landscape architects would declare that epoch as one of environmental crisis. And now, precisely 50 years later as we acknowledge their original Declaration of Concern the International Commission on Stratigraphy is expected to formally announce the dawn of the Anthropocene Epoch: a new geological period defined by the fact that the earth’s systems are now fundamentally and irreversibly altered by human activity.

The philosophical and practical consequences couldn’t be greater: in short, Nature, as Elizabeth Meyer, FASLA, noted, is no longer that ever-providing thing “out there,” it is, for better or worse, the world we have created and the world we are creating. The landscape of the Anthropocene is one of permanent ecological crisis. As such the Anthropocene is overwhelming, but since it is by definition a human creation, the Anthropocene is some thing we must take responsibility for, something we can design. This doesn’t automatically sanction the hyper modernity of geoengineering planetary systems but it does return us, humbly and critically to McHarg’s concept of stewardship.

As sketched in this essay, from the last 50 years of landscape architecture we have two dominant epistemological paradigms; positivism and constructivism; and three models of professional identity and scope; the landscape architect as artist (Walker), the landscape architect as regional planner (McHarg), and the landscape architect as urbanist (Waldheim). Rather than see these as competing models cancelling each other out, perhaps what we have really learned from the last 50 years is that each is somewhat incomplete without the other. If however we make a concerted effort to combine these various paradigms and models, we begin to give credence to the notion of landscape architecture as a uniquely holistic discipline, one especially well-suited to engage with the contemporary landscape of planetary urbanization and climate change.

So has landscape architecture failed? Yes and no! The small discipline of landscape architecture may not yet have impacted vast territories but it should be acknowledged for its lofty ethical concerns and for ranging so far and so wide in its pursuit of a relevant professional identity. And if in that pursuit it has been stretched too thin too far then rather that admonish it for failure, we see the last 50 years as a necessary process of preparation for this historical moment. For this is now landscape architecture’s century — all the major issues of the times are at root about how we relate to land — and if by the end of it we are still small, weak and ineffectual, and if the world is a worse place than it is now, then we will only have ourselves to blame.
