Impact: The Effect of Climate Change on Coastlines, aerial photographer Alex MacLean’s latest book, captures our Atlantic and Gulf coastal communities at their most vulnerable. Even in a media environment inundated with images of climate change, MacLean’s photos have the ability to shock.
Trained as an architect, MacLean is well-known for his decades-long work photographing landscapes from above. A cursory review of MacLean’s aerial photography shows a fixation with the seams and stitches at the edge of our built environment. Those interstitial zones offer valuable insight into our relationship with rising sea levels. Impact’s photos show us pristine lawns and asphalt driveways grafted on to lagoons, mansions pinned to subsiding cliffs, and suburban housing divisions encircled by tumultuous waves.
Impact’s photos are endowed with an instant nostalgia. Knowing that sea level rise is in the process of re-configuring the pictured landscapes, Impact feels similar to a yearbook, freshly published. “Remember when,” one might find themselves saying while flipping through the images years from now. Remember when Casino Pier extended proudly from the boardwalk at Seaside Heights in New Jersey? The Jet Star roller coaster perched on top, not crumpled in the water like it was found after Hurricane Sandy?
MacLean dedicates a portion of his book to the documentation of hurricane devastation, showing what high winds and flood waters can do to the built environment. But we’ve seen these photos before, haven’t we? And after Superstorm Sandy humbled Seaside Heights, Casino Pier was rebuilt, complete with a new roller coaster, Hydrus. So what lessons does Impact have for us that we haven’t already declined to learn? That depends on the reader, but MacLean’s photos will leave an impression, regardless.
Impact’s most sublime photos are those that maximize nature in the frame. It’s easy to cover the strip of land shown in some if his images with a hand, giving the page over to ocean. MacLean has captured the radical flatness of his coastal environments, where buildings and people are co-planar with the sea.
MacLean expresses slight repulsion at the opulence on display at some of the beachfront communities he photographed. The recreational boating, the ostentatious architecture. He seems to desire that nature be re-grafted back over the development.
It’s tough to argue with him given the glut of development MacLean photographs. Faux-Italian villas situated on barrier islands seems comical. So do the beachfront homes supported by more stilts than there is likely lumber in the house’s frame. MacLean cuts any humor though with images of the aftermath of devastating storms. Stilts remain upright, but there’s hardly a house left to support.
What many of us know and have come to accept is that our foothold in coastal areas is precarious. Most would acknowledge our coasts receding and anticipate our structures drowning. But we count on insurance recouping us. We may even choose to rebuild in hazard zones. Whether these two latter statements remain true, this stance underestimates the willful endangerment we’ve engaged in at the coast.
Perhaps Impact’s most striking photo is of the Sabine Pass liquified natural gas production facility in Louisiana, sitting directly in the path of future hurricanes. When critical infrastructure, energy, and waste facilities are impacted by sea level rise, we will be left with very different, less desirable memories than we hoped for.
The pandemic has created a global economic crisis, leading to a recession in some countries and a depression in others. While the U.S. is no longer facing a depression, like it did this spring, the country is now in the midst of the COVID recession, and landscape architecture firms are learning to adapt. In a session during reVISION ASLA 2020, firm leaders with Sasaki, SWA Group, and Mathews Nielsen Landscape Architects (MNLA) explained steps they are taking and their outlook for the coming year.
According to Michael Grove, FASLA, chair of landscape architecture, civil engineering, and ecology at Sasaki, a multi-disciplinary architecture, planning, and landscape architecture firm based in Massachusetts, the firm is focused on “putting people over profits.” To ensure the firm can meet payroll for its 250-300 staff, Sasaki is holding larger cash reserves while cutting pay for its partners, in the form of profits, by 20 percent.
Sasaki is also re-investing in its own capabilities. The firm has increased both internal staff training and investment in research and development (R&D). This enables the firm to “capture higher fees from thought leadership and research,” Grove said. The higher investment in research also allows the firm to benefit from federal and state R&D tax benefits.
Being multi-disciplinary has its benefits as well. “The diversity of our practice helps in different markets.” In China, which is now experiencing an economic recovery, Sasaki is a “known entity,” with an office in Shanghai, so can benefit from growth there.
But Grove cautioned there is worse to come in the U.S. “Design firms are usually impacted 6-12 months after a shift in economic conditions.” The firm is now seeing higher education clients put projects on hold, as universities and colleges rethink the use of their campuses in an increasingly hybrid in person-virtual world. In the commercial sector, some clients accelerated design and construction through the summer, but that is no more given “ongoing angst in commercial markets.” There has been a jump in civic or public projects in China, but in the U.S., “municipal budgets are now stretched thin” without additional fiscal stimulus.
Sasaki is now planning for a “decline projected by the end of the year.” To prepare for this, they are cutting travel and marketing expenses in order to keep cash and profits up.
SWA Group, a multidisciplinary firm that focuses on landscape architecture, planning, and urban design, has also benefited from being diversified. René Bihan, FASLA, managing principal in the firm’s San Francisco office, said SWA Group, which has some 250 employees and is 100-percent employee owned, is organized more like a starfish than a spider.
“If you cut off a spider’s head, it’s game over.” In the same way, in a spider-like organization, there is a “pyramidical hierarchy that suffers when leadership goes down.” In contrast, a starfish has multiple legs that can continue to live and regenerate on their own. An organization organized like a starfish doesn’t have a head. In the case of SWA Group, each of its eight studios spread around the world act somewhat independently and have their own cultures.
For example, their San Francisco office is mostly focused on policy and large-scale sites and has some technical experts. Other offices are known more for project design and construction. With their flexible structure, the firm can move staff and resources from one studio to another as markets grow or shrink.
SWA Group also purposefully keeps a diverse client portfolio. “Right now, 52 percent of our work is international,” with the bulk of those projects in China, Mexico, and the Middle East. Another 20 percent is public projects.
In adapting to the new normal, SWA has altered how it seeks out new business. “We do very few cold calls or RFPs. Instead, about 80 percent of business comes from repeat clients,” Bihan explained. “There is a familiarity. We continually check in with them, find out what they are up to, and look for ways to help them.”
Social media, books and blog posts, public engagement, and word of mouth are other “huge ways to get business,” he said. SWA has even leveraged pro-bono work, including parklets and neighborhood volunteer projects, to find new clients. “These projects can be launch pads.”
MNLA, a landscape architecture, planning, and urban design firm based in New York City, has a staff of 32 and is mostly focused on projects in the public realm. According to Molly Bourne, ASLA, a principal at the firm, MNLA has been investing in a more resilient structure for the past few years. With improvements in IT infrastructure, they were able to transition to all staff working from home relatively easily. “We are so thankful we invested in this transition.” It also helped a great deal that the office went paperless a few years ago, moving to all digital record keeping.
The firm purposefully maintains a balance between public and private projects. “We never go past a certain margin,” Bourne said. “With a diversity of revenues, we never put our eggs in one basket.”
The firm takes on a mix of conventional federal, state, and local government projects, along with projects that result from federal stimulus funds. The firm is also pre-approved for New York City and state “on-call” projects that can be “small and undefined, but can serve as survival work.”
At the same time, MNLA is being as transparent as possible about where things stand with staff, asking people to pitch in where needed. So far, “2020 is good and bad. We’re bobbing along, grappling with uncertainty, and remain very busy.”
Bourne said working during the first few months of the pandemic in NYC was particularly difficult. “It was an emotional time for staff. It was either very quiet or ambulance sirens.” MNLA continues to put staff well-being first. “Staff are our greatest asset.”
Conversation then turned to what the job market is like for landscape architecture students who just graduated or will be in coming months. This is one of the most challenging times to find an entry-level position, at least since ASLA has been keeping records. According to the latest survey, 65 percent of graduating students received no offer this year. Of those who received an offer, more than 40 percent saw the terms or location of their position change.
The speakers recommended job seekers leverage and grow their networks. Most jobs are found through contacts. “Folks mostly hire people they already know can provide value,” Grove said. “They want to hire from a known entity, or get a referral from a trusted source.”
Some more advice: stay flexible and be open to a range of possibilities. Be competitive; make yourself indispensable. Do informational interviews, which are low-pressure. Undertake contract work, which can turn into more permanent positions. Look beyond landscape architecture firms: the government, construction, facilities management — places where a landscape architecture education will be of benefit.
Climate change-driven migrations will occur more frequently. That was the message in a first-of-its kind session at reVISION ASLA 2020. Haley Blakeman, FASLA, a professor at Louisiana State University, said landscape architects can facilitate more successful migrations by acting as a conduit between scientists, planners, and the communities forced to migrate.
Blakeman explained her team’s efforts in helping to move the Biloxi-Chitimacha-Choctaw tribal community of Isle de Jean Charles, a small and increasingly submerged island in Terrebonne Parish, along the coast of Louisiana. The island has lost 98 percent of its landmass over the past 60 years.
“[Climate migration] is going to be happening in more and more places,” Blakeman said. Sea level rise is Isle de Jean Charles’ particular affliction. Elsewhere, drought, wildfires, and food insecurity will force movement.
Can landscape architects help lead these migration efforts? “Yes,” Blakeman said, but only by accepting their limitations and collaborating with migrating communities and a collective of multidisciplinary planning and design professionals.
In Blakeman’s case, this collective included geographer and resilience policy analyst Jessica Simms and sociologist Pamela Jenkins. Their expertise and knowledge of the Isle de Jean Charles community helped build a trusting relationship that has served the project well.
“It’s tricky business moving people from their home to another place,” Jenkins told attendees. “It is not an infrastructure project with a social component, but the other way around.”
Isle de Jean Charles is representative of many low-lying areas in Louisiana. The state thrives commercially on its proximity to the water. But between the oil and gas industry choking coastal wetlands and the incursion of the sea, Louisiana has lost over 1,900 square miles of coastal land in the last 90 years. Isle de Jean Charles has outpaced that trend, putting pressure on the islanders to secure their community’s future elsewhere.
The tribe worked with the State of Louisiana to secure federal funding from the U.S. Department of Housing and Urban Development for the move. The project is the United States’ first community-scale climate change-driven resettlement. 38 of 42 households on Isle de Jean Charles are participating, and 34 of those are moving together to a 500-acre site called “The New Isle,” according to Simms.
Simms and her team vetted about 20 potential locations in Terrebonne for re-establishing the islanders, only examining sites that were safely above sea level. 20 sites were narrowed to three, with five configurations. Site preference surveys made rounds in the community as members visited the sites.
Eventually, the community settled on a site favored by approximately 80 percent of its members, an hour’s drive from Isle de Jean Charles. Blakeman, Jenkins, and Simms liaised between the islanders and design team in order to tailor The New Isle to the community’s needs.
While this suggests a tidy process, Simms reminded the audience that forced migration is inherently traumatic. “Their identities are wrapped up in the island that is going away,” Simms said.
Most tribal members were born and raised on the island and are well attuned to the place. In a departure from previous policies, which barred those migrating from retaining ownership of their existing land, the islanders were allowed to maintain ownership and access to their land and homes, though not allowed to live there. This policy change was critical to achieving community buy-in.
This buy-in is critical to the success of any forced migration effort, Jenkins explained. She quoted a figure from Anthony Oliver-Smith, an academic in the field of disasters and their social impacts, saying 90 percent of such migrations fail. Existing social fault lines, poor communications between the community and the professionals involved, and a lack of available funds often doom climate migrations.
And while the Isle de Jean Charles migration is heading towards success, all of the speakers emphasized that it does not represent a model. There are lessons to be learned from the effort, but each future migration undertaking must be community- and context-specific.
Construction on the homes of The New Isle began in May and will finish in 2021, according to Simms. The new community will sit 12 feet above sea level.
It is especially gratifying to be recognized on the 120th anniversary of the birth of the man who established landscape architecture as “the mother of all arts”—Sir Jellicoe himself.
My Roots in the Village
I’d like to begin by talking a bit about my childhood, which ultimately had a profound influence on the way I’ve come to approach my work. I was born to a peasant family in Dong Yu village in southeast China’s Zhejiang Province. The village is located where White Sand Creek and the Wujiang River meet.
I swam in the creek during the summer and caught big fish when the monsoon season came. When I was small, I took care of a water buffalo, which grazed along the waterways and between the paddy fields. There were seven ponds, a patch of sacred forest and two big camphor trees in front of the village, under which many legendary stories about my ancestors were told.
The land was extremely productive. We planted three crops throughout the year, including canola, wheat, buckwheat, rice, sugar cane, peanut, sweet potato, corn, soybeans, carrot, turnip, radish and lotus.
The land and water were precious, but the weather could be unpredictable, so we had to design and manage our farm fields wisely, following nature’s cycle and wasting nothing, and adapting in order to make a living.
We worshipped the Earth God, Water God, and Yu the Great, the legendary king who knew how to manage water and plan the land. We also worshipped our ancestors, who had the wisdom of adapting to nature and cultivating the land.
In all likelihood, I would have followed in the footsteps of my father, who taught me how to cultivate the land, manage water, and be a productive farmer.
But it was a difficult time. Although we were a peasant family, we had also been landowners. During Mao Zedong’s Cultural Revolution, my family was labeled as members of the “landlord class.” Our land was seized and redistributed to communes, after which we collectively farmed it. More significantly for me, children from the landlord class were prohibited from attending school.
But in 1978, an army veteran who came to teach in my village, Mr. Zhou Zhangchao, caught up with me one day while I was riding my water buffalo home. He told me that Deng Xiaoping had reversed the policies that barred the children of the landlord class from going to school. I immediately enrolled in school and began studying hard to catch up.
In 1980, after 17 years working on the commune, I passed the national university entrance examination. I was the sole lucky university entrant out of 300-plus students in our rural high school.
On the Shoulders of Giants
By chance, I was chosen to enroll in Beijing Forestry University as one of 30 students in the entire nation to study gardening, which had been cancelled for ten years during the Cultural Revolution. I was fortunate to have some of the best landscape gardening professors in the nation as my mentors, including Wang Juyuan, the founder of the Landscape Gardening Program at the Beijing Forestry University; Chen Youming, my Master’s thesis advisor; and Sun Xiaoxiang and Chen Junyu.
In a certain sense, leaving the dusty countryside to make beautiful gardens in the city was a dream for me and my parents.
But when I finished college and was starting my career of teaching and making beautiful gardens for the city, I returned home to find that my village had been destroyed. The sacred forest and the camphor trees had been cut and sold off. The creek itself had become a gravel quarry, and the fish disappeared.
I began to ask myself: Was there something more I should be doing? What about my village and my fellow villagers? What about the land beyond the garden walls and beyond the city walls—where, at the time, almost three-quarters of a billion Chinese lived?
At this same time, I began looking abroad to learn more. In 1992, I was accepted at Harvard’s Graduate School of Design. I spent the next four years working with Carl Steinitz, Hon. ASLA, along with landscape ecologist Richard Forman and GIS and computing expert Stephen Ervin. I would often encounter Ian McHarg, Michael Van Vulkenburgh, FASLA, Peter Rowe, and others in the hallways.
For me, it was a tremendously exciting time. It was a chance to meld the village-level concepts of the Earth God, Water God, and Yu the Great, from my childhood, with the ideas of the great Chinese “gardening” masters—and some of the best minds in the West.
The concepts of landscape and urban ecology, people-oriented urbanism, landscape perception and revolutionary anthropology, landscape and architectural phenomenology, etc., enlightened the left side of my brain. Design works by contemporary masters including Peter Walker, FASLA, Laurie Olin, FASLA, Michael Van Valkenburgh, FASLA, Richard Haag, FASLA, Maya Lin, Martha Schwartz, FASLA, Peter Latz, Bernard Tschumi, and so on, inspired the right side of my brain.
It happened to be a time of great debate within academia, and I found myself fascinated by the tensions between design as political procedure versus design with nature, and art versus ecology.
I was captivated by two questions, which have subsequently driven my entire career:
Conservation vs. Development: Spatial planning based on the idea of balance –when land and space are limited, how can we balance ecological protection with development?
Sustainability vs. Beauty: The creation of Deep Form — what is the relationship between sustainability and beauty, how can we unite ecology and art?
After graduating, I was recruited by SWA in Laguna Beach, California. There, I was able to work with Richard Law, FASLA, on luxury properties, new urban development, and projects in the booming Asian market. Life on the beach was pretty good.
But while I was happily designing luxury properties and imagining the grandeur of new cities, I found that the land at home was under assault. Old buildings were torn down; hills were leveled; lakes and wetlands filled and polluted; rivers channelized and dammed; and public squares and boulevards were built at gargantuan size. It was the opposite of everything I had learned about how to create livable cities and landscapes.
And it turned out to be a national-scale challenge. Over 80 percent of Chinese cities suffer air pollution, which kills 1.2 million people each year. Flooding causes some US$ 100 billion in damage. Four hundred of 662 cities suffer water shortages. Seventy-five percent of the nation’s surface water is polluted, and 64 percent of cities’ groundwater is polluted. 50 percent of wetlands have disappeared in past 50 years, resulting in tremendous losses of wildlife habitat.
Meeting the challenges
(1) Start with Education and a New Identity
I landed at Peking University as a professor in 1997 and was immediately joined by my lifelong friend Li Dihu. Together we started the landscape architecture program in the Department of Geography. We hoped to help an important new profession establish a foothold across a vast landscape. But we had humble beginnings: We started with a grand total of 3 students. (Today, we have 200 students enrolled, with more than 600 graduates.)
But people still tended to see me simply as “a gardener,” with no relation to urban development, land and water management, flood control, or ecological restoration.
In China, there’s a legend about “The Land of Peach Blossoms,” a magical realm of peace, a sort of Shangri-La. To a certain extent, I have always thought of Dong Yu village, where I grew up—with the two big camphor trees under which I heard the stories of my ancestors and the sacred forest where they rest–as the Land of Peach Blossoms. And landscape architecture, to me, seemed a way to recover the lost Land of Peach Blossoms.
So I felt compelled to reclaim the importance of landscape architecture itself and began describing it as “The Art of Survival.” In doing this, I was inspired by Ian McHarg’s pugnacious call to arms: “Don’t ask us about your garden. Don’t ask us about your bloody flowers …. We’re going to talk to you about survival.”
We launched a new magazine, Landscape Architecture Frontiers, to promote our new approach. We brought in top thinkers in the field to lecture and held over 15 landscape architecture conferences to educate a young generation and begin creating a consensus.
(2) Trying to reverse the damage and inspire policy change
We felt that immediate action had to be taken to reverse the damage, so we launched the concept of “Inverse Planning” (反规划 fǎn guīhuà), which emphasizes the protection of existing natural functions and prioritizes what is not built—what should be protected instead.
I also realized that the only way to reverse the damage caused by conventional planning procedure was to convince decision makers to change the policies. So I kept writing and talking and lecturing to decision makers, from top authorities to township leaders. I delivered over 300 lectures to municipal decision makers and ministers.
In 2006, I made a proposal to then-Premier Wen Jiabao that, to my surprise and gratification, initiated the process of national security pattern planning and ecological red line regulation.
These two concepts help identify and protect critical landscapes to safeguard natural, biological, cultural and recreational values and functions, thus securing this wide range of ecosystems services essential for sustaining human society. The State Council has since issued four state regulations to safeguard national ecological security.
(3) The “Big Foot” Revolution
I also realized that bad decisions were being made simply because of a misguided mentality about civilization and misguided aesthetic sensibilities. For thousands of years, the “civilized” urban elite worldwide has insisted on the privilege of defining civilization, beauty, and good taste. Bound feet, deformed heads, and twisted bodies are only a few such expressions of cultural practices that, in trying to elevate city sophisticates above rural bumpkins, have rejected nature’s inherent principles of health, survival, and productivity.
In China, for more than a thousand years, young girls were forced to bind their feet in order to be able to be considered beautiful enough to marry urban elites. Natural, “big” feet were considered rustic and rural. The obsession with “little feet” sacrificed function and dignity for ornamental value.
Today, landscaping and city building, by far, are the most visible and extensive manifestations of the folly of civilization and aesthetic standards defined from above—what I think of as “little foot” urbanism and the “little foot” aesthetic.
On one hand, the “manicured little foot” grey infrastructure simply lacks resilience and is a waste of energy and materials. On the other hand, urban elites with “little foot” aesthetics trying to elevate city sophisticates above rural peasants have rejected nature’s inherent goals of health and productivity.
These kinds of “little foot” grey infrastructure and aesthetics are not only expensive, but also wasteful and unsustainable. China’s carbon emissions in 2017 accounted for 28 percent of the world total. And according to 2018 figures from the World Economic Forum, China consumes 59 percent of the world’s cement and 50 percent of its steel and coal.
So I began advocating for what I call a Big Foot Revolution. This movement begins with questioning some of the basic values I have mentioned above, and my hope is that it will mirror an earlier revolution in the way Chinese thought about their own bodies and culture.
In the early 20th century, The New Cultural Movement was launched by teachers and students at Peking University, and ultimately led to the rejection of foot binding and a re-embracing of the natural beauty of the human form.
I believe the Big Foot Revolution will happen at three levels of action:
Planning the Big Feet (planning ecological infrastructure across scales)
Creating Working Big Feet (creating nature-based engineering models inspired by ancient wisdom)
Making Big Feet Beautiful (new aesthetics to create deep forms).
“Planning the Big Feet” or planning ecological infrastructure across scales, is critical for securing ecosystems services, and weaving green infrastructure together with grey infrastructure. Inspired by the ancient concept of sacred landscape—and by modern game theory¬—I developed the concept of the Landscape Security Pattern, which focuses on protecting the critical landscape patterns needed to ensure that natural processes can continue.
“Creating working Big Feet” means creating nature-based engineering models inspired by ancient wisdom, particularly from agriculture. We have developed replicable modules based on traditional farming techniques of terracing, ponding, diking, and islanding to address climate change and related problems at a massive scale in a cost-effective manner.
In China, all rivers are dammed and channelized with concrete flood walls. China has more than half of the world’s dams greater than 15 meters in height. More than US $20 billion is invested to control flooding each year, but US $100 billion is lost and 10 million people are affected every year. We need to accept and embrace flooding as a natural phenomenon, and turn grey infrastructure into green to help temper the damage of inevitable floods.
Due to the monsoon climate, over 62 percent of Chinese cities suffer from urban flooding. How much more flooding could be managed better if nature-based solutions were implemented nationwide? Using sponge city concepts would greatly increase water resilience.
In China, 75 percent of surface water is contaminated. Globally, 85 percent of sewage goes untreated. But the landscape can be a living system to clean water. Terraced, constructed wetland can be used to remove nutrients through biological processes.
We have already incorporated many of these ideas at several parks throughout China. In Zhejiang Province’s Taizhou City, we redesigned the Yongning Park as a “floating garden” with ecological embankments that can reduce peak flood flow by more than half, and create a seasonally flooded natural matrix of wetland and natural vegetation that sustains natural processes. This park demonstrates an ecological approach to flood control and stormwater management, while also educating people about new and forgotten solutions to flood control beyond engineering.
In Zhejiang’s Jinhua City, water-resilient terrain and planted vegetation were designed to adapt to monsoon floods. A resilient bridge and path system was designed to adapt to the dynamic flows of water and people. The river currents, the flow of people, and the gravity of objects are all woven together to form a dynamic concord. This is achieved through meandering vegetated terraces, curvilinear paths, a serpentine bridge, circular bioswales, planted beds, and curved benches.
In Harbin, in the far north, we turned the Qunli Stormwater Park into a “green sponge” that filters and stores urban stormwater while providing other ecosystem services, including the protection of native habitats, aquifer recharge, recreational use and aesthetic experience, which together help foster sustainable urban development.
At Dong’an Wetland Park on Hainan Island, off the coast of southern China, creating a green sponge in the center of the urban environment was an essential adaptation strategy for increasing resilience to climate change, particularly in an area where tropical storms can easily overwhelm conventional drainage systems.
In this case, a heavily polluted 68-hectare site was filled with non-permitted buildings and illegally dumped urban debris. Inspired by the ancient pond-and-dike systems and islanding techniques in the Pearl River Delta, and using simple cut-and-fill methods, a necklace of ponds and dikes was created along the periphery of the park that catches and filters urban runoff from the surrounding communities.
In the central part of the park, dirt and fill were used to create islands that are planted with banyan trees to create a forested wetland. Both ponding and islanding will dramatically increase the water-retention capacity of the park and increase the eco-tones between water and land to speed up the removal of nutrients. The constructed wetland can accommodate 830,000 cubic meters of storm water, dramatically reducing the risk of urban inundation.
Along the Huangpu River in Shanghai, we designed Houtan Park as a regenerative living landscape on a former industrial brownfield. The park’s constructed wetland, ecological flood control, reclaimed industrial structures and materials, and urban agriculture are integral components of an overall restorative design strategy to treat polluted river water and recover the degraded waterfront in an aesthetically pleasing way. The 10-hectare park, which is 1,700 meters long, filters phosphorous and other nutrients from 2,400 cubic meters of water per day, which is enough water for 5,000 people.
The Meshe River in Haikou has suffered flooding due to the monsoon climate and water pollution caused by sewage and non-point source pollution from urban and suburban runoff. The river had been channelized with concrete for the sole objective of flood control, which destroyed its ecological resilience.
We used nature-based solutions to create resilient green infrastructure that has revived the river. The concrete flood walls have been removed and the river was reconnected to the ocean so that tides could once again enter the city. Wetlands and shallow river margins were reconstructed so that mangroves could be restored. A terraced mosaic of wetlands along the banks of the river was designed as natural water-treatment facilities that catch and cleanse nutrient-laden runoff, and a significant amount of wildlife habitat has been recovered in the dense city center.
The Mangrove Park in Sanya City, on the island of Hainan, is another example of nature-based climate resilience. To mitigate urban flood risk caused by climate change, it was critical to restore mangrove along the waterways and coastal shorelines. One of the key challenges was finding an efficient and inexpensive method to reestablish the mangrove habitat that had been extensively destroyed due to rapid urban development. To that end, fill composed of urban construction debris and concrete from the demolition of the flood wall was recycled on site.
Cut-and-fill techniques were subsequently used to create a gradient of different riparian eco-tones for diverse fauna and flora, particularly different species of mangroves. An interlocking-finger design was used to lead ocean tides into the waterways, while also attenuating the impact of both tropical storm surge and flash floods originating in the urban and upland area upstream, both of which can harm establishment of mangroves. This also maximized habitat diversity and edge effects, which increase the interface between plants and water; this, in turn, enhances ecological processes such as nutrient removal from the water.
The dynamic aquatic environment that follows the rise and fall of tides and provides several aquatic species with the daily water-level fluctuation they need for survival. Terraces between city streets and the river have been augmented with bioswales to catch and filter urban stormwater runoff. In just three years, an area of lifeless land fill within a concrete flood wall in the center of the city was transformed into a lush mangrove park. This type of mangrove rehabilitation can be implemented at a large scale efficiently.
In China, 60 percent of urban soil is contaminated, and conventional remediation is usually very expensive. In Tianjin’s Qiaoyuan Park, I wanted to show how we can let nature do the work, by using nature-based soil remediation techniques. Through regenerative design and by sculpting land forms and collecting rainwater, the natural process of plant adaptation and community evolution was introduced to transform a former shooting-range-turned-garbage-dump into a low maintenance urban park. The park provides diverse nature-based services for the city, including retaining and purifying storm water to regulate pH, providing opportunities for environmental education and creating a cherished aesthetic experience.
Making Big Feet Beautiful means promoting the new aesthetics to create deep forms. In this, I was inspired by Anne Whiston Spirn’s New Aesthetics that “encompasses both nature and culture, that embodies function, sensory perception, and symbolic meaning, and that embraces both the making of things and places and the sensing, using, and contemplating of them.”
The timeless interdependence of culture and nature is most visible in the bond between peasants and their farmlands, and practices such as cut and fill, irrigate and fertilize, frame and access, grow and harvest, recycle and save — all of which embody some of the principles of new aesthetics that inspired my design.
In Qinhuangdao, I put a ribbon on the river to frame and transform the messy nature into an ordered urban park. Winding through a background of natural terrain and vegetation, the “red ribbon” spans five hundred meters and integrates lighting, seating, environmental interpretation and orientation. This project demonstrates how a minimal design solution can dramatically improve the landscape, while preserving as much of the natural river corridor as possible during the process of urbanization.
China has 20 percent of the world’s population, but only 8 percent of the world’s arable land—10 percent of which has been lost in the past 30 years due to urban development. Our project on the Shenyang Jianzhu University Campus uses rice paddies to simultaneously define the structure of the landscape design and introduce a productive landscape into the urban environment. It is a demonstration of a method to resolve the tension between urban development and food production in today’s developing world.
In Quzhou’s Luming Park, we embraced the concept of agricultural urbanism. On a site surrounded by dense new urban development, we created a dynamic urban park by incorporating the agricultural strategy of crop rotation and a low-maintenance meadow. An elevated floating network of pedestrian paths, platforms and pavilions creates a visual frame for this cultivated swath and the natural features of the terrain and water. Using these strategies, a deserted, mismanaged landscape was dramatically transformed into a productive and beautiful setting for urban living, while preserving the natural and cultural patterns and processes of the site.
I have also tried to show the possibilities of reusing and recycling. While China has been on an incredible building boom, it has also demolished large parts of its cities. In 2003, for instance, some 325 million square meters of new buildings were constructed, while 156 million square meters was demolished. Thousands of villages and factories were wiped out.
The Zhongshan Shipyard Park near Guangzhou, inaugurated in 2002, was an effort to show that existing building and other structures can be incorporated into new development. The park reflects the remarkable 70-year history of socialist China and has been lauded as a breakthrough in Chinese landscape architecture. The original vegetation and natural habitats were preserved and only native plants were added. Machines, docks, and other industrial structures were retained not only for functional purposes, but also to educate and because of their aesthetic appeal. The park demonstrates how landscape architects can create environmentally-friendly public places full of cultural and historical meaning on sites not previously designated for attention and preservation. Its design supports use by the common people, as well as the environmental ethic that “weeds are beautiful.”
For over 20 years, we have tested and built over 500 projects in 200-plus cities and showcased numerous replicable models for healing and transforming our land at various scales.
Looking back, I have a better understanding of how my village-level landscape experiences, melded with modern concepts of landscape and urbanism, sustainability and aesthetics, which were developed by my many teachers and mentors, have helped me to address some of the common challenges that our profession is facing today.
I find myself thinking often of my roots in Dong Yu village. I think of King Yu the Great, who had the vision of healing the earth and living with nature. I think of the peasants who transform the landscape in which they live with their own hands. And I want to think like a king, but act like a peasant.
This is an incredibly sobering time to contemplate the relationship between humans and the natural world. The global pandemic is a powerful reminder that any belief in the conquest of nature is pure folly. We are all living in a new era of humility.
Yet I also believe that the pandemic—together with climate change—is also highlighting how important it is to create landscapes that can not only heal bodies and minds, but also the planet itself.
It is such a great honor to be in the company of the many great and thoughtful landscape architects who come together under the banner of IFLA. As former IFLA president Martha Fajardo said in 2005: “Landscape architect is the profession of the future.”
Thank you, and I wish everyone the best in collectively keeping ourselves and our loved ones safe.
I recently joined with landscape architecture faculty colleagues Bart Johnson, David Hulse, and Chris Enright, along with other scientists, in a study of wildfire risks in the southern Willamette Valley of Oregon. Our National Science Foundation project employed complexity science to simulate prospective landscape change and wildfire scenarios over fifty years. We simulated landscape change scenarios many times across an actual large area. The factors that influenced the simulations were different climate projections, consequent vegetation changes, likely behaviors landowners told us they would engage in, and fire behavior.
Very few of our numerous 50-year simulations suggested the likelihood of as many simultaneous, intense, and extensive wildfires as were seen in western Oregon in the first two weeks of September. This suggests the incidence of large and severe wildfires in the West is not linearly related to advancing climate change, as we and others have thought. With a warming climate, there may be more of an exponential, but still variable, growth in the incidence of large, and often simultaneous, very costly wildfires.
The extensive intensity of increasingly frequent wildfires promises to consume ever more forests, lives, and property in out-of-control ways, overpowering conventional wildfire prevention, amelioration, and suppression measures.
Outbreaks of multiple hazardous and simultaneous wildfires happen when several regional factors converge to produce “blowtorch” conditions. These can include extremely dry fuels (after months of drought), high temperatures, very low humidity, high winds, accumulated fuel loads, and forests stressed by advancing diseases and mortality. The resulting wildfires often exceed those of historically natural ones. Those natural wildfires tended to foster forest health because they often burned with less intensity, more variable intensity across landscapes, and less average overall acreage.
The only effective long-term solution is to reverse climate change, which will not slow down in the near term. But in the meantime, forests can be managed to be more resilient to fire.
Fuels reduction is the only known option to increase forests’ resilience. Prescribed portions of young or smaller trees, dead wood, and shrubs could be reduced in hundreds of millions of acres in the American West, and again, later on, in the forests of the eastern states. This is happening at a growing pace, but piecemeal, wherever funding and political support coalesce. It’s not enough to meet the larger challenge.
Sporadic projects tend to occur near suburban or exurban areas where risks are appreciated due to recent wildfires. In national parks, legal mandates promote the restoration of native, low-fuel ecosystems by prescribed fire, another method of fuels reduction. Badly burned forests must be replaced by more fire-adapted forests, but this is rare.
The implementation of an adequately extensive forest fuels reduction program is beset by ideological blame-shifting and politically prohibitive costs. There is also a shortage of well-trained professionals dedicated to this task, who can manage risks and build support for projects by sensitively and creatively engaging with local landowners and communities.
Conservatives deflect blame to scientific managers and conservationists by asserting that most forests have been “mismanaged” because they have not been freely and widely commercially thinned and harvested for wealth production at no cost to taxpayers. Ecologically-oriented environmentalists deflect blame to conservatives by asserting that most forests have been “mismanaged” because they have not been managed to emulate natural processes, like prescribed fire, as opposed to ecologically-destructive management geared only toward short-term profits. Everyone else is to blame in such incendiary partisan narratives: No one takes responsibility to fix the problems or bear the costs.
This broad, divisive notion of “mismanagement” is vexing. People dealing with real forests in real places can rarely identify a simple and obviously correct management approach. There are always questions of what, why, where, and when in decisions about budgets, biological systems, interacting and conflicting goals, alternative techniques, public and logger safety, wildlife, amenities, and the politics of local and regional stakeholders. Fuels reduction must be a major goal, but the best way to achieve this must be carefully tailored to each forest in its social and ecological context.
There will be forests where commercially profitable fuels reduction is appropriate, but there are many where this will be impossible, because costs exceed the value of marketable products.
There will be forests where prescribed fire is appropriate and efficient, but not everywhere. Numerous homes have been built within many forests. This makes prescribed fires more difficult to execute. Homeowners are often averse to perceived or actual risks, the intentional production of smoke, and changes to landscape amenities.
Climate change is also reducing the frequency and duration of weather conditions and fuel moisture levels required for safe prescribed fires. Prescribed fire is also difficult to safely control in increasing areas of forest with many weak or dead trees. If poorly planned, fuels reduction can impose risks to long-term forest health, net carbon sequestration, wildlife habitats, soils, biodiversity, and long-term sustainability of local timber or recreation economies; and it can’t be universally implemented.
A national program of extensive, well-planned forest fuels reduction and increased carbon sequestration would be very costly. Forest landowners are already shouldering growing insurance costs. It would require bipartisan, constructive, sustained, and large investments in public forest capital.
A complete, valid, and public GIS database of forest conditions in all western states must be rapidly created and maintained.
A private-public partnership with a clear mandate to foster forest health and resilience would need to award funds and coordinate and enable work across states, localities, landowners, and agencies. New, well-crafted rules would need to set fuels reduction and carbon sequestration goals with strong performance standards. These must clarify how projects must not be cheap and quick, but locally-appropriate to produce long-term forest health and beautiful, diverse forests.
Professional local planning, public participation, honest environmental reviews, and carefully proficient implementation would all be imperative.

The American Society of Landscape Architects (ASLA) announces the 2020 Professional and Student Award winners. The ASLA Awards represent the highest honor in the profession of landscape architecture.
Chosen from 567 submissions, this year’s 31 Professional Award winners represent the best of landscape architecture in the General Design, Urban Design, Residential Design, Analysis & Planning, Communications, and Research categories. In addition, a single Landmark Award is presented each year.
Chosen from 560 submissions, this year’s 35 Student Award winners represent a bright and more inclusive future of the landscape architecture profession in the General Design, Urban Design, Residential Design, Analysis & Planning, Research, Communications, Student Collaboration, and Student Community Service categories.
“ASLA’s Professional and Student Awards programs celebrate the best of our profession today, and the brightest hope for the future,” said ASLA President Wendy Miller, FASLA.
“From making sure Black, Indigenous, and People of Color (BIPOC) as well as other underserved individuals and communities prepare for the many challenges of the climate crisis – this year’s projects clearly demonstrate how landscape architects are designing a future that addresses the biggest problems facing our world.”
All Professional and Student Award recipients, their clients, and advisors will be honored at the awards presentation ceremony held virtually this fall.
Background on the ASLA Awards Programs
Each year, the ASLA Professional Awards honor the best in landscape architecture from around the globe. Winners of these prestigious awards are chosen by a jury that represents the breadth of the profession, including private, public, institutional, and academic practice, and exemplify diversity in professional experience, geography, gender, and ethnicity. Submissions are judged blind.
Professional Awards are presented in seven categories: General Design, Urban Design, Residential Design, Analysis & Planning, Communications, Research, and the Landmark Award. In each of the first five categories, the Jury may select one Award of Excellence and any number of Honor Awards. It is not guaranteed that an Award of Excellence will be selected each year, as it is up to the jury’s discretion. Only one Landmark Award is presented each year.
This year’s Professional Jury included: Jose Alminana, FASLA (Chair); Jane Berger; Ujijji Davis, ASLA; Mark Hough, FASLA; Mark Johnson, FASLA; Kathleen John-Alder, FASLA; Mia Lehrer, FASLA; Tanya Olson, ASLA; and Robert Rogers.
Student Awards are presented in eight categories: General Design, Urban Design, Residential Design, Analysis & Planning, Research, Communications, Student Collaboration and Student Community Service. Like the Professional Awards, the jury may select one Award of Excellence and any number of Honor Awards. It is not guaranteed that an Award of Excellence will be selected each year, as it is up to the jury’s discretion.
This year’s Student Jury included: Terry Guen-Murray, FASLA (Chair); Adam Arvidson, FASLA; Lucia Athens, ASLA; Cermetrius L. Bohannon, ASLA; Jonathon Geels, ASLA; Rikerrious Geter, Associate ASLA; Luis Gonzalez, ASLA; Melissa Henao-Robledo, ASLA; Ernest C. Wong, FASLA.
The pandemic didn’t stop this year’s Landscape Architecture Foundation (LAF) fellows in innovation and leadership from presenting the results of their year-long investigations. In an online symposium attended by more than a thousand people, six emerging leaders in the field of landscape architecture explained how design can help create a more just world. Each fellow received a $25,000 grant from LAF to travel, conduct research, and build their leadership skills.
Liz Camuti: Bad RFPs Set Back Resilience Planning Efforts
Liz Camuti, ASLA, a landscape designer at SCAPE (and we are proud to say, a former ASLA communications intern) told the story of Isle de Jean Charles in Louisiana, the homeland of the tribe of the Isle de Jean Charles Band of Biloxi-Chitimacha-Choctaw Indians. More than 98 percent of the tribe’s lands have been lost due to rising sea levels and coastal erosion. In 2016, the state of Louisiana received $48 million from the U.S. Department of Housing and Urban Development (HUD)’s National Disaster Resilience Competition (NDRC) to resettle the Isle de Jean Charles community.
After finding their concerns were ignored during federal and state planning processes, the community eventually decided to forgo resettlement. Camuti blamed the “so-called design solution handed down through the request for proposal (RFP).” This led her to examine the “centuries of problems with RFPs” issued by federal and state governments, and the awful position many planners and landscape are forced into of simply obeying the forms and “checking the boxes.” She called for communities and landscape architects to “uncheck the box” and push back against poorly-conceived RFPs.
As part of the RFP development process, all communities, and particularly indigenous ones, should be better consulted on how they want to be identified. Public participation processes, which are often a requirement, should be designed to air conflicts instead of minimizing them. Ample time should be given to establishing community ownership of a project through the creation of working groups and steering committees. Instead of coming in as experts, landscape architects need to reframe their relationship with communities with which they work and become much more humble about what they don’t know.
Diana Fernandez-Bibeau: Diverse Communities Need Heterogeneous Landscapes
“We design places for diverse species of plants and animals. Why not design spaces for diverse people?,” asked Diana Fernandez-Bibeau, ASLA, a senior associate at Sasaki. By studying ecology, which explores species diversity, and anthropology, which delves into human diversity, landscape architects can partner with communities to design places defined by “landscape heterogeneity.” This process involves weaving diverse social, cultural, linguistic, and environmental systems into a place.
Heterogeneous places are much needed, because there are already “too many homogenized public spaces in the U.S. that were not designed for people of color,” Fernandez said. “Landscapes are not neutral ground but poignant expressions of power.” Homogenized spaces are created by a colonizing power that minimizes difference.
As far as a process for creating heterogeneous landscapes, Fernandez argued that there is “no formula,” and what matters most is having a “state of consciousness” that is based in the “acceptance of the other.” She said diverse communities are more than capable of defining themselves. She pointed to the community design process for the new Frederick Douglass Memorial in Boston, in which an African American spoken word artist helped create a safe space for community sharing and spiritual growth.
Nicholas Jabs: Climate Change Is an Opportunity to Revitalize Middle America
“Middle America is too often ignored,” argued Nicholas Jabs, a designer with PORT Urbanism in Philadelphia, who gave a centuries-spanning overview of the region, from the Ice Age, which resulted in rich soil deposits, to the establishment of indigenous tribal communities, and the rise of fur traders. Communities like St. Louis, Chicago, and Minneapolis formed on rivers, because rivers were the major transportation system, but by the mid-1800s, railroads began to dominate and manufacturing spread.
Over the next few decades, middle American cities were transformed from “vertically organized” communities in which manufacturing co-existed with housing to “factory warehouse cities” characterized by the rise of “horizontal, specialized manufacturing zones” separated from housing. This led to urban and suburban sprawl, corporate campuses, and science parks. An ensuing multi-decade decline in American manufacturing was in part halted in the 00s by “flexible and urban” manufacturing that creates “high-quality crafts on demand.”
Climate change offers an opportunity for middle America. With its legacy infrastructure, resources, and manufacturing and distribution know how, middle America is poised to play a leading role in the mass mobilization of people and resources to reduce emissions and adapt communities. As communities address climate impacts, “we’re going to need to make and fix lots of things.” Middle America can lead with “craft, cultivation, community, and care,” which can transform the region once again.
Jeff Hou: A New Network to Grow Design Activists
Amid the grave environmental, health, and social justice issues facing the world, how can landscape architects make a difference? Jeff Hou, ASLA, a professor of landscape architecture at the University of Washington, formed a design activism working group across universities and landscape architecture organizations, which resulted in a 50-page framework of action based in a set of principles. There are now 800 professors and students sharing ideas in a collaborative online community.
Principles include: politicize, which calls for “understanding that the built environment is a result of a political process;” hybridize, which involves increasing cross-disciplinary collaboration; and “glocalize,” a new word combining globalize and localize as a way to encourage intercultural learning and connection. Other key principles are: improvise; problematize, which means to re-evaluate complex, interconnected issues; authentize; re-organize; and democratize, which is a call for “re-examining our systems of justice.”
Hans Baumann: The Value of Immersion in the Culture of Indigenous Peoples
Hans Baumann, an independent landscape architect in Santa Monica, California, spent his fellowship with the Torres-Martinez Indians, whose 22,000 acre reservation is adjacent to the Salton Sea, California’s largest body of water. The sea is expected to lose a third of its volume within a decade because of climate change and agricultural water use, with major impacts for the cultural and spiritual practices of the tribe.
The Salton Sea is found within the footprint of the much larger prehistoric Lake Cahuilla. The Torres-Martinez have long had a deep cultural connection to the sea and the lands around it. Baumann partnered with the tribe on a series of slow creative projects, including community workshops and other landscape interventions with the goal of building relationships and trust with the tribe.
After two months of coordination, the tribe and Baumann were able to organize a kayaking event for tribal youth out on the sea, so that young people could create a “more positive relationship with the water.” Surveys showed that the tribal youth changed their perspective of the sea to “cool, fun, and awesome” after the event. He concluded that he invested in long-term relationship building and is purposefully not leading the way. “I don’t have the solution.” Baumann encouraged landscape architects to research the many tribes in the U.S., their historic homelands, and get involved, but to also recognize that “work is already being done in communities.”
Pierre Bélanger: A Call for Accountability to Indigenous Peoples
Pierre Bélanger, a landscape architect, urban planner, and “settler scholar” who founded the non-profit organization Open Systems Landscape Architecture Lab, turned his screen black and read from an email he wrote to Brad McKee, the editor in chief of Landscape Architecture Magazine. He exhorted the audience to take greater responsibility for their historical impacts on communities and the environment. “Who are we — landscape architects — accountable to?,” he asked.
Bélanger called for greater accountability to indigenous peoples and an end of “settler capitalism,” which he argued still persists. “Since every square inch of land in the U.S. and Canada is treaty land, I wrote ‘No Design on Stolen Land‘ in Architectural Design Magazine earlier this year with a group of close colleagues that I had been working with over the past decade: Ghazal Jafari, Pablo Escudero, Hernan Bianchi Benguria, Tiffany Kaewen Dang, and Alexandra Arroyo.” He explained that “the article may seem foolishly polemical or unnecessarily provocative, or totally impractical as some have shared, but at a time when profound structural and systemic change is needed, we as practitioners and educators can no longer afford to ignore, let alone deny, the inseparable nature of climate change and colonialism to change the present.”
We are living where we shouldn’t be living. In more communities across the U.S., climate change is causing flooding, wildfires, extreme heat, and sea level rise. According to a group at the Congress for New Urbanism (CNU)’s Virtual Gathering, one solution is for communities threatened with climate impacts to move to “receiver cities.” The hollowed-out “legacy” cities and small towns of the Midwest could become new homes for displaced climate migrants because they have solid infrastructure, many open lots and empty homes, access to water, and lower risks of climate change-driven weather impacts.
Still, more planning is certainly needed to ready receiver cities for an influx of migrants from coastal communities like Miami, which are experiencing rising sea levels and flooding, and desert communities in the Southwest, which are battling drought and reduced water supplies.
Legacy cities are former industrial communities that have fallen on hard times. Dan Baisden, a midwest urban planner, said these mid-sized cities in Ohio, Michigan, Pennsylvania, and West Virginia, have experienced population declines, job losses, and increased concentrations of poverty. “Braddock, Pennsylvania has seen a 90 percent drop in population, and Johnstown, Ohio, a 70 percent drop.” While these legacy cities may be good places for climate migrants, they also aren’t “fully ready to accept them.” Through the CNU Legacy Labs project, he is helping these cities devise climate adaptation plans that “build density and social structures.”
There are other planning efforts underway to help guide migrants to safer places. Scott Bernstein, founder and director emeritus of innovation at the Center for Neighborhood Technology (CNT), is developing a series of urban climate action plans, mapping instances of extreme heat, drought, and flooding. He has located the places with the highest and lowest frequencies of severe weather, heavy water events, and bearing winds. His goal is to identify the communities with the lowest risk of climate dangers.
Similarly, architect and urban designer Dhiru Thadani is examining development patterns of 120 communities in the U.S., including dozens of small towns, to determine which could best expand to handle population growth and a large influx of climate migrants. He noted that the U.S. population is expected to grow by 100 million by 2050.
Large influxes of climate migrants could happen sooner than expected. Patty Steinschneider, president of Gotham Design & Community Development, asked us to envision 100,000 people moving north from Brooklyn, New York, in the immediate aftermath of some major natural disaster like Superstorm Sandy. Communities near Brooklyn need to plan for emergency receivership as well as a potential long-term permanent influx. Just as many who have fled cities because of COVID-19 will not return, not all climate migrants will be able to or want to return to their original communities.
Baisden noted for a community like Toledo, Ohio, which has a very small planning staff that is already overrun with existing responsibilities, planning for a rapid influx of, say, just 100 families would be very challenging. “They have no long-term planning capacity. We instead need to work directly with communities on the ground.” Onaran said communities could possibly designate “receiving zones.”
For Jesse Carpentier with ICLEI USA, there is a lack of long range climate adaptation planning because its value hasn’t been sold well. “People act on emotions rather than logic. Immediate gratification will always be more appealing than long-term benefits.” So these planning efforts, which have a multi-decade horizon, need to bolster stakeholders through short-term incentives like awards, recognition, and certificates, “which really do work.” Adaptation efforts must also have “tangible co-benefits” for communities in the form of economic gains and aesthetic improvements.
So what can potential receiver communities do to prepare for both climate change and incoming climate migrants? Recommendations included creating comprehensive policies that incentivize migration, developing plans for reusing and adapting existing community assets, and investing in green infrastructure and planting thousands of trees. Communities can also let others know they are open and welcoming of climate migrants.
Prisca Weems, a founding partner with interdisciplinary firm Future Proof, noted that climate migrants will not just be an issue within the U.S. A 2018 report from the World Bank finds that 143 million people are now already migrating in-country each year.
Throughout the Congress for New Urbanism’s Virtual Gathering, landscape architects, planners, architects, and developers struggled to figure out how the pandemic is impacting communities and the built environment — and tried to foresee what changes are coming in the near future.
Black, Indigenous, and People of Color (BIPOC) communities will experience disproportionate negative impacts in the form of higher mortality rates, illnesses, bankruptcies, and evictions. Some also foresee a significant decrease in public financing for affordable housing developments.
There is also the fear that people are retreating to their cars, which are now viewed as “armored bubbles,” and to the suburbs — a trend that could lead to greater suburban sprawl, increasing transportation costs, and a steep rise in greenhouse gas emissions.
A few optimists argued that dense cities and communities, along with affordable and subsidized housing, multi-family housing, and transit-oriented development, will weather the storm. People will still be drawn to walkable communities and being near one another. Resilient communities will find a way, like during other recessions.
Low-income Communities Are at Greater Risk
In a session that looked at low-income neighborhoods in cities, Kit McCullough, an urban designer and lecturer at the University of Michigan, emphasized the need to protect and invest in communities where hospitality and restaurant workers live — places where COVID-19 is already exacerbating existing economic strain.
Small affordable housing property owners facing financial problems are increasingly at risk of being bought out by large Wall Street-backed development firms. This would result in more “wealth extraction in low-income communities” in the form of higher rents and increased evictions.
Many people who used to rely on transit to get to work must now use a car, which is a more expensive transportation option and “adds economic pressure.”
John Sivills, lead urban designer with Detroit’s planning department, added that “if you can decamp from the city, that says something about your income level.” In Detroit, the community has “rediscovered the value of public spaces” given most don’t have the funds to leave.
COVID-19 Requires New Urban Models
In another session, Mukul Maholtra, a principal at MIG, focused on how COVID-19 is impacting BIPOC communities much more than others.
“Black Americans die from COVID-19 at three times the rate of white Americans.” In tribal lands in New Mexico and elsewhere, “there are much higher fatality rates among Native Americans.” He called for investing in “healthy density” that works for everyone.
Christopher Leinberger, a land use strategist, developer, and author, said correlations between COVID-19 and metropolitan area density are “spurious and unproven.” He said “walkable urbanism has been through this before — crime, terrorism, and now the pandemic.”
There are three challenges to a rebound in cities: “lost jobs in the ‘experience economy’ — retail, restaurants, sports, and festivals — which is what makes ‘walkable urbanism’ special; transit safety; and land costs.”
He blames zoning and not-in-my-backyard (NIMBY) forces for skyrocketing land costs and gentrification in cities like Washington, D.C. The answer is allowing greater density where land prices are high and making walkable, mixed-use development legal in more places.
Public Financing Will Be Increasingly Unavailable
Andrés Duany, an architect, planner, and one of the most influential New Urbanists, said a total “rethink of New Urbanism is needed,” because the public funds that make many walkable developments possible have disappeared.
The pandemic is expected to have a negative impact on city and state budgets into the near future, which means far less public funds available for transit, affordable and subsidized housing, transit-oriented development, and the public portions of public-private partnerships. “Everyone is broke. There will be no capital budget and no tax credits anymore.”
Demand for walkable communities as currently defined will decrease. “Home deliveries are way up because neighborhood ‘third places‘ [such as coffeeshops, book stores, grocery stores, etc] have become toxic. And transit now equals death.”
Duany also foresees a rise in social instability in the U.S., and perhaps gangs of “marauders.” This is because “110 million Americans have no savings” and are facing rising healthcare costs and unemployment and failing social safety nets.
He proposed rapidly expanding mobile home communities, given they are subject to fewer regulations and therefore lower cost. Abundant and cheap old shipping containers could be used as the base of new modular mobile home reached via a staircase.
Through her research into 2,000 suburban developments that have been retrofitted for other uses, she has found that “urbanism is the new amenity.”
In the suburbs, people increasingly want walkable, mixed-use developments that offer “experiential retail.” Dead malls have meant growth for small town main streets. Dead strip malls are being reused as offices or healthcare centers. Big box stores have been converted into markets with small vendors.
“The pandemic could mean more urbanites return to the suburbs. Office parks could be refilled, instead of infilled. There could also be more experimental suburban public spaces.” In this scenario, the car is an “armored bubble” that offers a sense of safety in a world filled with dangerous viruses.
But ultimately, she thinks the pandemic will mean walkable places will become even more valuable. If you can live and work from anywhere, “the quality of place will matter even more.”
Demand for Different Residential Amenities
In a session focused on how home design may change with COVID-19, Paul Whalen, a partner at Robert A.M. Stern Architects, said with many people cooped up at home, “visual and audio privacy, cross-ventilation, and multiple rooms that provide space for extended family” are becoming more important.
Homeowners and renters also now want separate spaces for making the transition from street to home, a “clear entrance where they can change out of clothes and take off shoes.”
Interior designer Kiki Dennis sees a changing relationship between public and private spaces within homes. Home offices are becoming semi-public domains that co-workers can see on Zoom, so they are being expanded and re-configured.
There is also much greater demand for residential outdoor spaces. “Underused outdoor spaces are being converted.”
“Ultra-luxe residential fixtures” like automatic sliding doors, face and hand readers, and personal elevators may trickle down to the masses, said Brian O’Looney with Torti Gallas + Partners. In some buildings in the Middle East, when an elevator is in use, it is locked and can’t be accessed by others in the building. This technology could become more widespread in denser cities.
Bill Gietema, a developer with Arcadia Realty Corporation, said people are buying homes online without seeing them in person.
“People want double ovens so they can bake more, expanded kitchens, home offices, workout spaces, and porches.” Some are simply lifting their garage doors to create a porch-like environment.
Multi-family housing complex designs are also shifting to include much more outdoor space and larger balconies.
A recent survey of developers that create large-scale community developments found that 16 percent are adding more shade; 22 percent, more parks; 23 percent, more trails; 57 percent, more bike lanes; and 42 percent, more playgrounds, which are now incorporating natural materials rather than steel and plastics. “There is a new desire to create a sense of community.”
In the end, though, Whalen believes many people who have fled cities will return to them. “People all want to be together. That’s why people live in cities.”
Once a vaccine has been developed, “there will be a joy in coming out of this together.”

What change do you think can result from the killing of George Floyd by the police and the Black Lives Matter protest movement against racial injustice and police violence? The movement has become global and supported by millions of people.
That’s a hard question. My first response is that we’ve been here before. In light of the pandemic and other things, I’m really hesitant to say there’s going to be some major changes in the way black people are regarded and accepted in our society. We’ve had these moments before.
What makes it really hard, as a person of color, is understanding our history. In my short life — I’m in my early 60s — I grew up in a segregated neighborhood. My school was integrated when I was in junior high. For the first time, at age 13 or 14, I started living with other people who didn’t look like me.
That’s the hardest and most difficult thing we’re not talking about: the racial construction of this country. We’ve only had 50 plus years where we’ve actually lived together in an integrated way. We have close to 300 plus years of living separately. So the idea that we can just all of a sudden flip the switch and people will change and accommodate the “other,” it’s a really tough one.
I don’t think we’re asking the right questions. You’ve listed these facts and metrics. Why are these numbers so high? When one looks back, why are we still policed in similar ways? Why are people of color harmed at a greater frequency?
In a country that was “separate but equal,” there had to be an institution to keep that separation and keep people in their place. We have had close to 100 years of the Jim Crow institution, keeping us in a subservient place. This is U.S. culture. Even post integration, we still have to look at these institutions, which go back to the founding and the development of the country. You can’t separate the two. We would like to, but they’re inextricably tied together.
It’s important to allow these issues and histories to come to a greater light and clarity, because now more people are interested in trying to understand this predicament than I’ve ever seen in any point in my life. The pandemic has a lot to do with it. People are thinking about the future. Everything is unsettled at this moment, and all the pieces have come together. It’s the perfect storm.
Black Landscapes Matter, a book you co-edited with Grace Mitchell Tada, which will be published November, came out of a lecture series you initiated in 2016 following police killings. In your book, TED Talk, and other writings, you have called for planning and designing landscapes that allow for a diversity of narratives and perspectives, instead of homogenized landscapes that just say one thing to one group of people. How do you bring out these different memories and histories in a landscape?
After the spree of police killings in 2016, we wanted to bring together people who could articulate different voices in the black community. I wanted the book to articulate what’s missing in how we design for other narratives, which is about difference. I say difference, not diversity — it’s about different ways of interpreting the world. When one puts out multiple narratives, they challenge the singular and its maintenance.
I’m thinking a lot these days about difference and sameness. Colonialism is about sameness. It takes difference and makes it into sameness. It does that to promote and maintain its construction. W.J.T. Mitchell talks about a double reading of landscape, a double semiotic.
Colonization is happening inside the colony, as ideologies are projected outside the colony. Our projection — America, home of the free, and the brave, diversity for all, “all men are created equal” — is sent out to the world. The Statue of Liberty, “give me your tired…” — all of these things. But inside, we’re being re-colonized to keep that narrative intact.
But that narrative is being torn. People are looking for other ways to see themselves and others around them. So in Black Landscapes Matter, we talk about different story lines.
If more people are aware of what is part of their environment, not just today but yesterday, and possibly even tomorrow, we’d have a different way of thinking about the world. In so many spaces in this country, something happened! It has not always been vacant and desolate, places exist! Placemaking is re-colonizing. Something is always there if you are interested in it.
Many of your projects are specifically focused on unearthing hidden layers, creating spaces for multiple consciousness. The International African American Museum in Charleston, South Carolina, tells the story of slaves arriving in the port of Charleston and their descendants. A master plan for the Rosa Parks neighborhood in Detroit, Michigan, explores the history of the movement for racial equality. Double Sights, a public art piece at Princeton University, expands the interpretation of the many sides of former Princeton and U.S. President Woodrow Wilson. Navigating through all these layers of history, how do you get to the essentials and make planning and design decisions that really resonate?
For me, it’s the willingness to want to unearth. Your previous question had to do with memory and history, which is a little different than unearthing.
Sometimes places are palimpsests, meaning part of the brick and mortar, and some of them are based in memories, the passing of time. For people of color who are marginalized, stories get lost. Each project is fraught with chance. I am not trying to solve a problem, per se. I’m trying to put something out in the world that has been covered up, erased, which might allow people to see the world and themselves in a different way.
Privilege at times only produces singular narratives, which is what happened with the Woodrow Wilson project. The students at Princeton still want his name off the building, so the piece has not resolved the issue. But what I hope the piece does is allow that issue to always be there. If someone at Princeton University said “remove the name of Wilson,” then the piece wouldn’t exist.
With the International African American Museum, there are clear, bold design statements. How do you really focus in on certain aspects of history and tell a broader story through design?
The design decisions for the landscape are very personal and I am consciously having conversations with those before me. I approached the Woodrow Wilson project through the narrative of W.E.B. DuBois, who has always been part of my thinking as a black man, and his idea of double consciousness. That gave me a point of view to criticize Wilson.
As for the International African American Museum in Charleston, the final was not the boldest design. We developed 29 different designs and worked through each one with the community. From my personal point of view, I wanted to put out imagery that had never been put out before. I took it upon myself to push the community. The Black Body in Space is something that really intrigued me conceptually.
For the Rosa Parks neighborhood in Detroit, I approached the project, again through history and identity. I’ve spent years with my peoples’ history. My research and design work has lived with these histories — not just American history but the history of black America.
Returning back to your larger question: I could have gone through practice with no interest in black history. I could have just accepted the privileged position of the designer. I could just work in the very homogeneous/standardized manner in which the profession trained me.
In my early years, that was really all I had to rely on, until I got to a point where it felt like something was missing. What was missing was myself. I did not see myself anywhere in landscape architecture, architecture, or planning. At the offices I worked, these ideas just didn’t exist. I had to create a context for my ideas to bear fruit, so I situated myself in the rigorous, intellectual world of academia and developed an art practice. This is what I’ve been doing the last 30 years.
Do you think because you’ve found yourself in your work, people can find themselves in it, too? Is that what creates a sense of resonance, when someone sees your work and connects with it?
No, they actually hear a different voice, which again, is playing off the homogeneous. Early on, I noticed the design decisions I was making were different than the decisions other people were making. I didn’t acquaint them because I’m black. It’s because of my advocacy for and interest in people and the particular places that they live, which comes from my experience of being black.
Very early, one of my projects in a disinvested neighborhood involved planting an allee of a hundred and fifty flowering trees at one time along a decomposed granite walkway. This was 30 years ago, and people weren’t doing stuff like that. To me, I wanted color to manifest in a bold way in a place that didn’t have color.
Those design choices came out of me seeing a black community in need of something. As a person making landscapes, that is what I could give them. I always go back that very simple act — that purity of impulse one has in a place where you’re engaged but also giving of yourself. And this relates to the questions: what are you feeding yourself? Where’s the inspiration coming from?
I try to bring in as much culture as I can to the work, which can offer multiple narratives and layers. I’m really not interested in singular gestures, but multiplicities.
People are yearning for difference. I just recently stopped using diversity and started using difference, because diversity is not really about difference. Difference is about opposition. Opposition is good. Double negatives are good. They exist in our world.
The doubles begin to tell stories we don’t tell. We see it in the language that is manifest over time by culture. You’ll see spaces given double negative terms, like Plaza Park. I was in San Jose, California, when Hargreaves was working on Plaza Park. I was like, “Plaza Park? Oh, this is interesting. Why does it have both?” If you go and look at the history, you know why it has two. These are the kinds of things people create over time through naming, adopting. Landscapes have a language.
If we’re critical enough, we can begin to read the landscape in different ways. Once you do, it changes you forever. There’s no way to go back.
Washington D.C. Mayor Muriel Bowser and the city government have painted “Black Lives Matter” in street-bounding yellow letters down 16th Street, NW in front of Lafayette Square and the White House. This was widely viewed as a response to President Trump’s order to teargas protesters and close off Lafayette Square — a key protest space and site of a former slave market — from public access. How do you unpack everything going on in that space? What is the role of public space in the protest movement?
In the history of this country, streets have been that number one space for protests. We can go back to women’s suffrage and civil rights. The streets are the public domain. In D.C., what’s public and what’s federal? That’s the interesting dichotomy in D.C. Lafayette Square, which is federal, gets acted upon differently than the city public. When I heard that, I was like, wow, I didn’t know the President had dominion over that particular space.
Protesting has always taken place in the public realm. You can go back to Kelly Ingram Park and the Edmond Pettus bridge. These are my first memories: people protesting in the streets. This is nothing new. The marking, particularly with the branding, might be something new, a kind of guerilla tactic. I applaud the mayor for doing it, because she was able to demark a space. People are calling it the plaza, but again, this it is about nomenclature. I applaud her for marking a space that was taken away from her.
Lafayette Square, like a lot of public squares, was among the first public parks in our country. They were also places where atrocious things happened in our country like slavery auctions, so they’re on hallowed ground to a degree. If we’re interested in changing how we think of ourselves, we can also be critical of the places where we’re actually protesting. To me, that could give credence to, or help articulate, issues we’re facing, particularly with the pandemic.
We know most low-income areas have higher cases of COVID, which you could also probably correlate to redlining policies and expulsive zoning, which was an institutional pre- and post-war planning practice. Redlined landscapes are still the same today if we are still in them.
Public safety is important. People should be allowed to use the spaces we have seen over the past few weeks, whether it’s the I-5 in L.A. or bridges in Minneapolis. These are spaces the public pays for.
You have equated the value of environmental diversity with that of social and racial diversity. Just as land comprised of diverse ecosystems are more sustainable and resilient, racially diverse or different communities also increase social sustainability and resilience. How can the fight for racial equality and justice support efforts to combat climate change and vice-versa? What are the connections?
The first connection one might think about is duplication. There really are two Americas, and we’re actually trying to support both of them, not equally though. There’s one America for one group of people and another for the other. It’s just not sustainable, because we’re having to spend more money on communities that are different, which is a result of the after-effect of not investing in these places in the first place. How to make communities more racially diverse is our next challenge.
We’ve been talking recently about a few new mixed-income housing projects in Oakland, California. When we think of mixed incomes, we think race, right? We can think of brown people, low-income; non-brown people, higher incomes. What might allow them to share the same space? That’s the question we’re beginning to ask. It comes back to public space, right?
We can develop parks and other types of landscapes that are more integrated into peoples’ patterns and practices, so they can begin to share space. The architectural question is a bit more difficult, because a lot of that is driven through the market.
As for environmental diversity, I’ve lately returned to reading Olmsted and early Central Park history. In Go Tell It On the Mountain, written by James Baldwin, he describes an experience in Central Park one day. He goes to this hill. It’s his favorite hill. When he gets to the top of that hill, having walked from Harlem to Central Park, with all the white eyes upon him, he’s king of the world. He could do anything. He’s standing there looking out to Manhattan. He’s on this hill in the middle of nature, and he could do anything, and then slowly reality comes back to him. He descends the hill and runs into an older white guy. Immediately, he’s about to apologize, but instead the man smiles. That moment is how I think about what landscape can do. In a certain way, how do we put ourselves together in a place where there is no label or stereotype of the other? That’s really tough to do, as we recently saw with that woman in the Ramble.
Gentrification of urban Black and brown communities most often results in their displacement. Some communities have viewed efforts to add new green space and trees to their communities as a gentrifying agent. So one response has been the “just green enough” design movement, which calls for adding green amenities but not to the extent that they would raise property values. What is your take? What approaches work best to stop displacement? And how do you think the protest movement can change conversations in communities where gentrification is happening?
All communities should be healthy. If we have the opportunity to increase biomass and improve the public-realm facilities in any community, we should do it. The fear of making something better particularly for those most vulnerable — really.
We should look at the issues that create the vulnerability. In many places, you have a high percentage of renters and low ownership. Some places you have little to no tax base. You have these institutional issue that don’t help. The first steps in some places are to figure out new and diverse housing types, increase ownership, and stabilize communities.
When communities were most healthy, successful, richest — whatever word you want to use to characterize them– they were diverse places. West Oakland has the moniker of having always been an African-American neighborhood. If you review its early formation, people came here because it was the western terminus of the railroad. Different communities of people worked and lived here: Latinos, Hispanics, African-Americans, Portuguese, Italians, etc. Post-war we see white flight, and then desegregation. First immigrant and then middle-class African Americans had opportunities to move into the places that whites had left. We then abandoned those redlined neighborhoods and left the most vulnerable.
That’s the dynamic of the city. We have to articulate these dynamics to communities in which we work and help them understand these processes.
I live in an area that was once redlined. There are single-family houses mixed with light industrial. It’s a pretty diverse, mixed neighborhood. Next to my building, there was no green space at all. People reacted to vacantness in various ways, which was to tag the walls, dump garbage or leave abandoned elements. I took it upon myself and started planting trees and shrubs adjacent the building. My little piece is the greenest part of the block.
What’s been refreshing and a reminder is watching how people reacted. Almost every day, the neighbor across the street tells me how great it is to see the green. People walk on my side of the street, and the behavior has changed. These are just little things that I just think we forget.
Part of our job is to help educate communities in which we’re working, based on shared knowledge. We can build an infrastructure to help with change, because change is going to happen. Cities are dynamic.
Very early in my career, I had a conversation with a black family here in the East Oakland neighborhood about moving out of the city. They wanted to move to the suburbs because the schools were better, and the crime was lower. I couldn’t change any of that from my position.
So the issues become more structural. We have to improve these basic infrastructures like public education and environmental factors. In many of the places where gentrification happens, they’re so easy to topple because all of the infrastructure is eroded.
In 2013, ASLA’s member leadership made diversifying the profession a top organizational priority. The number of diverse people entering the profession remains stubbornly low. The high cost of landscape architecture degree programs and lack of alternative degree programs are issues. So is the lack of diverse landscape architects who can advocate for the profession in diverse communities. What do you think are the most important steps that can be taken to bring more black and brown young people into the profession?
Landscape architects: just set the example. Make it interesting for people of color, so they want to come into the profession. This means you have to change the narrative. Reach out, do the work. Approach the way we make things through a cultural lens. Look for difference, so people might get excited by seeing and experiencing something that has them in mind.
Throw away the stereotypical and the feel good tropes — basketball, barbeques, community gardens. It would be attractive for people to say, “wow, this is how I can improve my neighborhood. Look at what they’re doing,” rather than settling. Really dig deep and contemplate these histories, the years of living separate.
How do we talk about living together? If enough of us are out making change and having a different conversation, the idea of attracting a diverse group becomes secondary.
Years ago, I was part of a landscape group that was pushing for diversity. You can’t expect to attract people if there is no interest in change.
I get excited when people of all persuasion get excited by the work we’re doing. It’s not about whether the project gets into a magazine and wins awards. To me, the best reward on any project is to get people excited, empowered, bringing them in, and making them part of the project.
I had recalled years ago as an undergraduate, I met a black landscape architect, Everett Fly, who had uncovered some of the histories of these towns that were built during Reconstruction. That experience stayed with me, and when I had the opportunity to have a conversation with that work, I immediately began to ponder the semiotics of this term used to describe black and brown people. What does it mean to be F-R-E-E-D!
It took a lot of nerve for me to start this conversation since it was something I had never entered into a conversation with a community about. I can’t describe the kind of excitement and conversation that began from there.
We can bring more voices to the table when we discuss, gender, race, and difference. Tell the truth about colonization and its impact not just on native and immigrant communities, but on the black and brown communities as well. If we don’t talk about it, we are reinforcing a post-colonial view.
This will bring difference into our profession, so it’s not simply just about making beautiful things. It can become about what those beautiful things mean. Once we can attach diverse meanings to the things we make, our profession could be much more inclusive.
For maybe two-thirds of my projects, race never comes up. To me, that’s where we should be heading. I don’t want the moniker of “black designer.” I can design for anyone, because I’ve had to learn how to. This skill came from being the “other,” and having to learn about white America and how to navigate, which is what we (others) don’t see happening from white America, right? I don’t see that kind of investment in me.
All I hear is, “Walter, help me. I’m working in a black community. I need you.” No, you don’t need me. You need to do the work for yourself. You need to learn about us. You need to get in there and roll up the sleeves. This is not my (our) problem. Until it changes, we’ll be back in the same position 20 years from now, asking why we’re not a diverse profession.
