The Planetary Health Framework: The Way to Achieve a Sustainable Future

Planetary Health: Protecting Nature to Protect Ourselves / Island Press

Humanity has become totally out of synch with the planet’s biophysical systems — for proof, just look to climate change, COVID-19, environmental degradation, ocean acidification, and the accelerated extinction of species. As we now begin to understand, the planet is a single organism, a complex, inter-connected system that can either be healthy and in balance — or not. Furthermore, our health and well-being are intrinsically connected to the health and well-being of natural systems.

In Planetary Health: Protecting Nature to Protect Ourselves, a new book edited by Drs. Howard Frumkin and Samuel Myers, we are given a roadmap for how to undo the damage to the Earth and live in a way that is more respectful of the planet’s limited capacity. The authors convince us to take this path not just for nature’s sake but also for our own future health and well-being.

Dr. Howard Frumkin is former Dean of Public Health at the University of Washington and former director of the National Center for Environmental Health at the Centers for Disease Control and Prevention. Dr. Samuel Myers is principal research scientist at the Harvard T.H. Chan School of Public Health. Together, they have put together a thought-provoking and rich 500-page overview of the emerging field of planetary health, which is increasingly used by UN organizations, governments, non-profits, and universities as a framework for understanding the relationship between human and environmental health.

Frumkin and Myers and their contributors build their case so methodically, with loads of persuasive data, that by the end of the book, it seems difficult to imagine a better framework for understanding Earth’s contemporary human-environmental dynamics. This book is a must-read for anyone passionate about creating better outcomes for more people, far into the future.

In their introduction, the editors explain how today is “the best of times and the worst of times.” On one hand, it has “never been a better time to be a human being.” In the past 65 years, the percentage of the world’s population living in extreme poverty fell from 63 percent to 10 percent, despite the population tripling in size. Child mortality rates are the lowest in recorded history.

But on the other hand, human activity is “driving biophysical change at rates that are much steeper than have existed in the history of our species.” 40 percent of the planet is now dedicated to agriculture, at the expense of natural systems. Habitat destruction and the anticipated extinction of up to a million species threatens the underlying biodiversity that maintains the resilience of natural systems.

Some may see promise in the Anthropocene, the new geological epoch created by humans, and imagine a future planet optimized by direct human control. But in reality, the poor human management of the planet’s biophysical systems to date means that more of the status quo will lead to civilizational collapse.

According to Frumkin and Myers, we have disrupted the climate system; polluted air, water, and soils; caused rapid biodiversity loss; reconfigured biogeochemical cycles; made pervasive changes in land use; and depleted fresh water and arable land. These changes all have significant health implications for billions of people. A new approach rooted in planetary health is needed.

The book first provides a background on the intellectual history of the concept of planetary health, which only began as a systems-scale field of research in the 1990s. As Dr. Warwick Anderson explains in his essay, the field made a big leap in 2010, when The Lancet, a major research journal, and the Rockefeller Foundation partnered with other public health groups to promote a “new health discipline — public health 2.0.” In 2015, with the release of the seminal Lancet – Rockefeller Foundation commission report Safeguarding Human Health in the Anthropocene Epoch, Richard Horton, editor of The Lancet, deemed the new field of inquiry “planetary health,” which Anderson states, “rapidly gained currency.”

The book then lays out the scale and complexity of the problems and offer some positive models to addressing them:

A chapter by a team of esteemed researchers from organizations such as the Population Council, Population Reference Bureau, and Population Institute explore how the growth in human population and consumption are driving environmental change. They argue that “given the tight interconnectedness of the two drivers, it may be best to see them as coequal challenges.”

These contributors call for disincentivizing the excessive consumer consumption of the U.S. and western Europe, which would doom the planet if expanded to a global scale. They also point to the connected drivers that can further reduce population growth, including greater investment in the education of girls and women around the world, which helps to empower them to make their own decisions, and the expansion of access to contraceptives.

Their conclusion: a “multi-pronged strategy that integrates education, sound policies, and high-quality health services — all while guaranteeing the rights and respecting the dignity of all people — could dramatically accelerate the transition to truly sustainable levels of human population and consumption.”

A companion essay outlines the environmental impacts of the twinned growth in population and consumption. The authors argue: “We live on a different planet than the one our great-grandparents called home a century ago. It is a warmer planet, a more crowded planet, a planet with fewer species, a planet marked by widespread contamination and altered biogeochemical cycles.”

In this chapter, we learn about humans’ many impacts on the environment — ranging from the climate to the nitrogen cycle in agriculture, from land use and cover to water scarcity, biodiversity loss, and pollution.

Through a series of essays, Planetary Health delves into how those specific environmental changes — all driven by human behavior — are in turn jeopardizing human health and well-being by increasing risks in the area of nutrition, infectious diseases, non-communicable diseases, population displacement and conflict, and mental health.

In the section on nutrition, Myers explains how rising temperatures and carbon dioxide levels increase risks in the agricultural sector, impacting everything from the amount of time farm workers can stay in the heat to the nutritional yield of important mainstay plants. He also flags the lack of genetic diversity of the few plant species we rely on and the need to greater protect plant diversity.

A chapter on infectious diseases by Richard Ostfeld, with the Cary Institute of Ecological Studies, and Felicia Keesing, a biologist at Bard College, explains the growing risks of various infectious diseases. They write: “key environmental drivers, such as climate change, biodiversity loss, land use change, pollution, and alteration of biogeochemical cycles cause changes in the abundance, distribution, physiology, and behavior of important species involved in the transmission of both zoonotic and nonzoonotic pathogens to humans.” They analyze the relationships between land use, biodiversity, and diseases like malaria, lyme disease, and schistosomiasis, among others.

Non-communicable diseases, which include cardiovascular diseases, cancers, chronic respiratory diseases, diabetes, and other conditions, account for 70 percent of global deaths each year. In this chapter, Frumkin and Andy Haines, a professor at the London School of Hygiene and Tropical Diseases, lay out the data on how climate change, urbanization, and air pollution increase non-communicable disease risk. Of particular interest for landscape architects and planners is a section on the dangers of automobile-dependent communities.

A team of researchers then connect the dots between environmental change, migration, conflict, and heath impacts, explaining how the conflict in Darfur, Sudan, is now understood as the first “modern climate change conflict,” and how we can expect more to come.

One of their arguments for investing in climate solutions is worth re-stating: “Adaptation to global environmental change is part of preventing migration. Adaptation can reduce vulnerability to both sudden shocks and long-term trends. Examples include switching farming practices to drought-tolerant crops and soil-conserving techniques, not building in floodplains, constructing levees and sea walls, restoring coastal barrier systems (mangroves, vegetated dunes, coral reefs, wetlands), and altering building codes to put key utilities on roof instead of in basements.”

Susan Clayton, a professor of psychology at the College of Wooster, provides a much-needed overview of the expected mental health impacts of climate and environmental change. She collects many useful studies in one place, providing a valuable reference.

One worrying conclusion: “Higher temperatures can provoke increased aggression. This manifests in many ways: from pitchers beaning batters during baseball games and drivers aggressively honking their horns, all the way to violent crime, particularly when combined with frustration over limited access to resources, such as fresh water or arable land.” One of her key solutions is expanding access to nature, particularly in cities. “Reconnecting with nature…offers a range of direct and indirect mental health benefits.”

Planetary Health then turns to building the case for systemic changes in our societies and economies, including a shift away from using gross domestic product (GDP) as a measure of growth and instead using gross national happiness and other metrics that better account for human health, well-being, and environmental health. Central arguments include: “happiness and human health are intertwined; natural environments make people happy; and happiness production is not resource-intensive.” In other words, more experiences in nature create happiness, not the latest purchases.

After wading through the problems, we then get to the solutions — healthier models for various sectors: energy, chemicals, cities, economic development, and private sector growth. The chapter on urban places and planetary health is particularly worth reading as it makes the health argument for “integrated green urbanism,” transit-oriented development, bicycle infrastructure, and urban food systems. Iryna Dronova, a professor of landscape architecture at UC Berkeley, contributes to this discussion. The chapter on chemicals outlines how to reduce the risk of endocrine disruptors and create new green chemicals.

This significant new book also proposes how to create a set of planetary health ethics that can guide current and future action — a mutual promise to do no further harm in our era of climate and environmental change. Here, the contributors call for a “social movement, a scientific framework, an attitude towards life, and a philosophy of living that fosters resilience and adaptation.”

The core message: If we truly commit to maximizing human and environmental health in all communities, and undertaking all that entails, we will get on a pathway to saving the planet.

Kongjian Yu Wins 2020 Sir Geoffrey Jellicoe Award; Read His Full Speech

By Kongjian Yu, FASLA

I am honored to be chosen as this year’s recipient of the Sir Geoffrey Jellicoe Award. I would like to extend my sincere thanks to the International Federation of Landscape Architects (IFLA), the members of the nomination committee and the jury, and to everyone else who has made this possible.

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:

  1. Planning the Big Feet (planning ecological infrastructure across scales)
  2. Creating Working Big Feet (creating nature-based engineering models inspired by ancient wisdom)
  3. 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.”

Zhongshan Shipyard Park / Turenscape

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.

New Urban Solutions Needed for COVID-19 and Racial Injustice

COVID-19 has brought significant complexities to cities. Protests sparked by the murder of George Floyd and countless Black lives have filled our streets and public open spaces. Community leaders and designers, who are already scrambling to solve immediate public pandemic-related health issues, must take a hard look in the mirror and finally address systemic racism.

As the design professions investigate the way forward, many cities and communities are heading towards an uncertain future without a roadmap for addressing the pandemic and urban inequality.

In Seattle’s Capitol Hill neighborhood, a new normal has emerged through a center of protest against racial injustice, known as the Capitol Hill Occupy Protest (CHOP). The site organically formed as a result of protester standoffs with Seattle police officers in the streets, even while the pandemic has closed most of the city.

In an unexpected twist, the City of Seattle closed the police station and essentially gave the streets to the protesters. Nearly six blocks of city streets and Cal Anderson Park, a large Olmsted-designed park, have been occupied by hundreds of people who are redesigning the community.

Cal Anderson Park now includes freshly dug communal gardens and campers. The nearby streets are hosting bands, documentarians, speakers, and a shared food coop, art, and volunteer aid stations.

The creation of CHOP did not involve typical community meetings, street use permits, planning, and design. But the space galvanized Seattle’s historic undercurrent of resistance to expose injustices in Seattle.

CHOP is unlikely to survive long term but still demonstrates how quickly communities are re-organizing.

In April — prior to Mr. Floyd’s murder and the spontaneous creation of places like CHOP — seven University of Washington (UW) College of Built Environments Ph.D. students engaged community leaders, educators, urban planners, and landscape architects in a discussion on their predictions for a post-pandemic urban future. This conversation resulted in the Pandemic Urbanism Symposium held in May.

One panel discussed the importance of public space in the context of the pandemic and within the framework of equity, justice, and resilience. The panel was opened by UW faculty members Jeff Hou, ASLA, moderated by Catherine De Almeida, and featured four panelists: Jesús Aguirre, superintendent of Seattle Parks and Recreation; Cary Moon, citizen activist; Brice Maryman, FASLA, a principal landscape architect with MIG; and Cary Simmons, program director at the Trust for Public Land.

Of primary concern to all panelists was equitable access to public spaces from a social, economic, racial, and ethnic perspective.

The pandemic will further exacerbate inequalities in cities like Seattle, with a particular impact on Black, Indigenous, and People of Color (BIPOC) communities. One question lingered: how will the design professions simultaneously cultivate pandemic-resilient cities and break down the barriers of systemic racism?

Panelists discussed both long- and short-term solutions.

One important long-term solution, which could be similar to the New Deal of the 1930s, is to make a significant and equitable investment in public infrastructure — parks, housing, healthy ecosystems, and sanitation access. Greater investment in public infrastructure can help ensure prosperity for all citizens.

Other solutions include the Seattle Street Sink, which was designed and installed by a team of local architects and landscape architects. The innovative system creates immediate and equitable public access to hygiene, which can help stop the spread of disease. The simple act of washing one’s hands should be available to everyone.

Seattle has permanently closed 20 miles of streets to vehicular traffic. Street closures provide safe recreational opportunities and support community development.

Public park parking lots can be used as space for temporary housing, providing a place to live that has access to natural and recreational opportunities.

With the pandemic and protest movement, the door to address injustice, inequality, and the unhealthy nature of cities has been thrown wide open, creating opportunities for imaginative actions.

My Brown Privilege

Melissa Henao-Robledo, ASLA

By Melissa Henao-Robledo, ASLA

As a first-generation Latina, I’m a person of color who believes in the significance of Black Lives Matter and expanding diversity in the field of landscape architecture.

An individual’s journey shapes their professional life. But having a profession is not always the case for Black, Indigenous, and People of Color (BIPOC), who live daily with implicit bias resulting from systematic racism.

Instead of continuing to watch and navigate white privilege and fragility, it’s time for everyone to “get comfortable with being uncomfortable” and partner with the Black design movement.

The “there’s no one to hire” response doesn’t cut it anymore. The good news is you are already creative designers and planners who champion solutions every day. Now you can champion change within your workplace and industry.

Early education is the key to spreading awareness of landscape architecture. Commit to mentoring K-12 students. With the recent shift to virtual meetings, mentoring a student anywhere in the United States is possible. Collaborate with your local ASLA, AIA, and APA chapters that have established K-12 outreach programs. Ask your firm to attend high school career fairs. Volunteer for ASLA’s Virtual Career Day and openly express your support to welcome and embrace diverse voices and life experiences.

During my master of landscape architecture education at North Carolina State University, I was fortunate to have a Latino professor, Fernando Magallanes, ASLA, who I related to not only because we looked alike but also because we freely and openly expressed our Latin selves. Rodney Swink, FASLA, was also pivotal in my engagement with ASLA.

Both he and Fernando have introduced the landscape architecture profession at the Hispanic Educational Summit hosted by the North Carolina Society of Hispanic Professionals.

Kofi Boone, FASLA, professor of landscape architecture at NC State, continues to inspire. Reading Kofi’s Black Landscapes Matter, I’ve learned about Black landscapes in North Carolina that I was not aware of — and I grew up in North Carolina.

I’m very fortunate and proud to work for a company that is committed to equity and embraces my boisterous cultural identity. For several years, they have demonstrated their ongoing support by sponsoring panel speakers, webinars, and workshops that elevate diversity in the landscape architecture community.

Firms can invest in a diversity, equity and inclusion strategic plan and hire a facilitator to guide your company through the process. Read the ASLA Diversity Summit reports and elevate the voices of the LGBTQIA community. Are you familiar with LEED’s project team checklist for social impact?

Use your company’s voice and platform to share the work your colleagues are doing. This is a great way for BIPOC to get a glimpse into your company culture.

Do your project renderings and photo shoots include BIPOC, people of a variety of ages, and people with disabilities? Have you considered the inclusive or exclusive message these images portray?

Aprende Español! The ASLA Activity Book en Español is a great resource to learn the fundamental vocabulary of landscape architecture. Make the effort to communicate with your Latinx colleagues and employees en Español.

As we endure the COVID-19 pandemic that is literally wiping out BIPOC, the country has exploded with protests that call for safety and socio-economic equity.

I know what it means to feel afraid for the safety of my Black loved ones because they are identified by the color of their skin, not by their contribution to society, educational aspirations, smiles, love, and joy they bring to the world.

During a protest in Austin, Texas, I was in awe and bewilderment to discover protesters had shut down Interstate 35, the same interstate that divided Austin to create a “Negro District” via the 1928 master plan and subsequently was segregated by design to create a “ghetto for African Americas.”

During the protests, as I stood there in my truth, in my brown privilege, I felt a tremendous sadness for the lack of diversity in the landscape architecture profession.

Have you ever had to consider the lack of diverse representation of your race in your office, company, or profession? And the pain and sense of injustice it causes?

By the year 2043, the U.S. Census Bureau projects the nation to become a majority-minority nation.

My hope is practitioners will seize the moment and cultivate the future voices of landscape architecture that reflect the communities we serve.

Interview with Walter Hood: Black Landscapes Matter

Walter Hood, ASLA / Hood Design Studio

Walter Hood, ASLA, is the creative director and founder of Hood Design Studio in Oakland, California. He is also a professor at the University of California, Berkeley, and lectures on professional and theoretical projects nationally and internationally. He is a recipient of the 2017 Academy of Arts and Letters Architecture Award, 2019 Knight Public Spaces Fellowship, 2019 MacArthur Fellowship, and 2019 Dorothy and Lillian Gish Prize.

An estimated 1,000 people are killed while being arrested by the police in the U.S. each year. According to studies, young black men are killed by the police between nine and 16 times the rate of other groups, and black people overall are killed at three times the rate of whites. Furthermore, the U.S. leads the world in killings by police. Canada, which also has high gun ownership rates, has less than one-seventh the rate of police killings of civilians. Many European countries count just a few deaths by police each year.

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.

Double Sights at Princeton University / Hood Design Studio

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.

Master plan for Rosa Parks neighborhood in Detroit / Hood Design Studio

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.

We are currently working for the town of Nauck, Virginia. It’s a town square. Working with the community very early on the discussion centered on the Freedmen’s Village of Arlington Cemetery and the black diaspora that emerged when they were removed. Many in Nauck are descendants.

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.

Racial Injustice and the Pandemic Are Inextricably Linked

“I want to express my discomfort that we, as privileged white people, are discussing racial injustice without African American speakers on this panel. I want us to reckon with that,” said Allison Arieff, research and creative director at SPUR and op-ed contributor to The New York Times, during a plenary at the Congress for New Urbanism’s Virtual Gathering.

The non-diverse panel comprising Arieff, Emily Badger, a reporter for The New York TimesThe Upshot blog, and moderator Todd Zimmerman, principal at Zimmerman/Volk Associates, reached the conclusion that the twin crises of the COVID-19 pandemic and racial injustices are inextricably linked.

The pandemic and racial injustice protest movement are “exposing how poorly our systems work,” Arieff argued. As SPUR outlined in its recent Letter to White Urbanists, “the city is under strain because these places are not safe and healthy for everyone. White people are the problem and have to fix it.”

Badger, who covers all facets of urban policy for the Times, has been wrestling with a number of questions related to the pandemic when she realized the impacts of COVID-19 were connected with structural racism.

At first, she sought to answer big questions about the pandemic, such as: “Can we reconcile the benefits of density with its risks? Will a fear of density cause people to move to the suburbs? Will a fear of transit cause people to use cars more? Will transit agencies survive the collapse in funding? Will people working from home stay there permanently?”

With the understanding that racial inequalities in housing, education, transportation, land use are all connected, questions shifted to: “How does the police fit in with all of this? They are a part of this ecosystem of inequality and maintain racial segregation. What is their role? Why have segregation and poverty levels hardly budged since the 1960s? Why have income and racial inequalities become even worse? Should we spending more on housing than the police?”

Badger found that “COVID and race are not separate stories. Racial disparities and inequalities are feeding COVID and driving the protests.” Furthermore, COVID is likely to leave “lasting damage in the movement for racial equality,” as everything from deaths from the virus to evictions due to loss of jobs will be disproportionately higher in communities of color.

“Many of us working from home are protected and isolated. We don’t need to acknowledge how poorly the system works for most people,” Arieff said. “But the pandemic shows how fragile the social safety net is. Unemployment insurance doesn’t cover a huge set of workers. We can’t shut off evictions. Many didn’t realize schools feed a vast number of low-income students. Homeless people are now of interest because they could be carrying disease. All our structures are inadequate and need to be deeply rethought.”

One structure that many are calling for a total rethink is the police force. A recent analysis of police budgets in 150 cities by the Times found that police departments on average account for 8 percent of city budgets, and those numbers have gone up over the past 40 years even as crime has declined.

As police forces have grown, they have taken on more responsibilities. “They are now working with homeless populations and in schools. They have become mental health counselors and intervene in domestic abuse,” Badger explained. There is growing debate in many cities about taking away some of their responsibilities or defunding them. “Now that we know the jobs that they are doing, do we want them doing them?”

The ever expanding responsibilities of police forces is linked with the reduction in federal funds for social services and anti-poverty programs. Given there are no other groups mediating what is acceptable behavior in public spaces, “police have by default taken on the role,” Badger said. Instead, “community groups could take over some of the roles police are now playing.” Arieff commented that perhaps defund the police movement could be rebranded as “lightening the load.”

The debate turned to how the built environment professions — planners, architects, landscape architects, engineers — need to change how they work. Arieff said that “there is no easy, pat answer. Design is a top-down, white male-dominated field. But these issues aren’t limited to the design industry.”

The power structures in the built environment “controlled by white people have benefited them. White neighborhoods benefit from exclusionary zoning laws. Property values increase when there is no affordable housing near you,” Badger said.

Arieff argued that critical next steps are to “listen more and make greater effort to recruit panels of color for design conferences.”

To survive and grow, the design world needs to diversify. As an example, she pointed to Next City, a publication focused on cities, that changed the make-up of its editorial staff, significantly diversifying its team of writers. The result was that “readership massively diversified and grew.”

The conversation then veered to whether the concept of “eyes on the street,” and crime prevention through environmental design (CPTED) in general, unjustly target people of color.

Arieff argued that “it’s not all or nothing. I’m not ready to dismiss the concept. There are different contexts and behaviors. We can’t homogenize all places. Different people of color use public space differently. We must be more open to how different cultures use public space.”

Zimmerman, the moderator, added that a once common description of a healthy city was that it was safe for a 7 year old. He thinks this should be changed to “safe for a 7 year old black child.”

Suburban Sprawl Increases the Risk of Future Pandemics

By Michael Grove, ASLA

The export of American culture is one of the most influential forces in our interconnected world. From Dakar to Delhi, American pop music, movies, and artery-clogging cuisine is ubiquitous. However, one of the most damaging exports is the American suburb. When the 20th century model for housing the swelling populations of Long Island and Los Angeles translates to 21st century Kinshasa and Kuala Lumpur, the American way of life may very well be our downfall.

In our pre-pandemic ignorance, most urbanists pointed to climate change as the most dangerous impact of our cherished suburban lifestyle. To be sure, the higher greenhouse gas emissions and rise in chronic health problems associated with living in subdivisions aren’t going away, but COVID-19 has exposed another threat we’ve chosen to ignore. The next pandemic may very well result from our addiction to—and exportation of—sprawl.

Vilifying Density and Disregarding Equity

The increasing traction of the anti-density movement in the wake of the current outbreak is alarming. Headlines proclaiming how sprawl may save us and that living in cities puts citizens at higher risk for contracting the novel coronavirus are deceptive.

Recent studies have debunked these myths, finding little correlation between population density in cities and rates of COVID-19, instead attributing the spread of the virus to overcrowding due to inequity and delays in governmental responsiveness.

Mounting evidence suggests that COVID-19 is primarily transmitted through close contact in enclosed spaces. Internal population density within buildings and, more specifically, within shared rooms inside buildings is what drives this, not the compact urban form of the city. In New York, for example, COVID-19 cases are concentrated in the outer boroughs, and suburban Westchester and Rockland counties have reported nearly triple the rate per capita than those of Manhattan.

The real issue is the systemic economic inequity that forces lower income people to live in overcrowded conditions, regardless of location. Innovative approaches to urban planning, equitable housing policies, and a reversal of over a century of environmental discrimination in our cities are absolutely necessary. Vilifying the city is counterproductive.

Moving out of dense cities into the open space and social distancing afforded by the suburbs is exactly the type of knee-jerk reaction that we must avoid. Cities are not at fault.

Habitat Fragmentation and Biodiversity Loss

In fact, cities are the answer if we plan them carefully. Among the many human activities that cause habitat loss, urban development produces some of the greatest local extinction rates and has a more permanent impact. For example, habitat lost due to farming and logging can be restored, whereas urbanized areas not only persist but continue to expand.

The Atlas for the End of the World, conceived by Richard Weller, ASLA, a professor of landscape architecture at the University of Pennsylvania, is one of the best sources for documenting our collective risk. Mapping 391 of the planet’s terrestrial eco-regions, this research identified 423 cities with a population of over 300,000 inhabitants situated within 36 biodiversity hotspots. Using data modelling from the Seto Lab at Yale University, the Atlas predicts that 383 of these cities—about 90 percent —will likely continue to expand into previously undisturbed habitats.

When we assault the wild places that harbor so much biodiversity in the pursuit of development, we disregard a significant aspect of this biodiversity—the unseen domain of undocumented viruses and pathogens.

According to the World Health Organization, approximately 75 percent of emerging infectious diseases in humans are zoonotic, meaning that they are transmitted to us through contact with animals. The initial emergence of many of these zoonotic diseases have been tracked to the parts of the world with the greatest biodiversity, both in the traditional and man-made sense. Traditional locations include tropical rainforests where biodiversity naturally occurs. Human-influenced conditions include places like bushmeat markets in Africa or the wet markets of Asia, where we are mixing trapped exotic animals with humans, often in astonishingly unsanitary conditions.

However, degraded habitats of any kind can create conditions for viruses to cross over, whether in Accra or Austin. The disruption of habitat to support our suburban lifestyle is bringing us closer to species with which we have rarely had contact. By infringing on these ecosystems, we reduce the natural barriers between humans and host species, creating ideal conditions for diseases to spread. These microbes are not naturally human pathogens. They become human pathogens because we offer them that opportunity.

This is already evident in the fragmented forests of many American suburbs where development patterns have altered the natural cycle of the pathogen that causes Lyme disease. When humans live in close proximity to these disrupted ecosystems, they are more likely to get bitten by a tick carrying the Lyme bacteria. When biodiversity is reduced, these diluted systems allow for species like rodents and bats—some of the most likely to promote the transmission of pathogens—to thrive.

This essentially means that the more habitats we disturb, the more danger we are in by tapping into various virus reservoirs. COVID-19 is not the first disease to cross over from animal to human populations, but it is likely a harbinger of more mass pandemics and further disruptions to the global economy. The more densely we build, the more land we can conserve for nature to thrive, potentially reducing our risk of another pandemic from a novel virus.

Portland’s Urban Growth Boundary

In the United States, over 50 percent of the population lives in suburbs, covering more land than the combined total of national and state parks. Our urbanization is ubiquitous and endangers more species than any other human activity.

In 1979, Portland, Oregon offered a pioneering solution with the creation of an Urban Growth Boundary (UGB). Devised by a 3-county, 24-city regional planning authority, the intent was to protect agricultural lands, encourage urban density, and limit unchecked sprawl.

Forty years into this experiment, Portland’s experience is a mixed bag of successes and missed opportunities. Investment in public transit and urban parks has certainly bolstered the city’s reputation as a leader in urban innovation, sustainability, and livability, with statistics to support its efforts.

On the other hand, two of Oregon’s fastest growing cities are situated just beyond the boundary’s jurisdiction, underscoring the limitations of the strategy. Again, inequity rears its ugly head, with higher prices within the UGB caused, in part, by an inability to deregulate Portland’s low density neighborhoods. This has driven much of the regional population further afield to find affordable housing in the form of suburban sprawl beyond the UGB’s dominion and into even more remote areas.

Another consideration that was overlooked when the original plan was established was the adequate protection of remnant habitat within the UGB. This lack of a regional plan for biodiversity protection has underscored the need for a more ecologically-focused, science-based approach to inform planning decisions.

Brisbane’s Bird Population

Unfortunately, anticipating outcomes of urbanization on species diversity is not as pervasive in urban planning agencies around the world as it should be. A lack of detailed modeling specific to individual regions and cities with clear recommendations for how to minimize ecological devastation is absent from planning policy around the world.

However, researchers in Brisbane, Australia have attempted to quantify which development style—concentrated urban intensity or suburban sprawl—has a greater ecological consequences. By measuring species distribution, the study predicted the effect on bird populations when adding nearly 85,000 new dwelling units in the city. Their results demonstrated that urban growth of any type reduces bird distributions overall, but compact development substantially slows these reductions.

Sensitive species particularly benefited from compact development because remnant habitats remained intact, with predominantly non-native species thriving in sprawling development conditions. These results suggest that cities with denser footprints—even if their suburbs offer abundant open space—would experience a steep decline in biodiversity.

This is a common outcome found in similar studies around the world that exhibit a comparable decline in the species richness of multiple taxa along the rural-urban gradient. Although biodiversity is lowest within the urban core, the trade-off of preserving as much remnant natural habitat as possible almost always results in greater regional biodiversity.

Helsinki’s Biodiversity Database

One of Europe’s fasted growing cities, Helsinki faces similar pressures for new housing and traffic connections as many other major metropolises. However, in Helsinki, geotechnical and topographic constraints, coupled with its 20th century expansion along two railway lines rather than a web of highways, created the base for its finger-like urban and landscape structure. Today, one-third of Helsinki’s land area is open space, 63 percent of which is contiguous urban forest.

In 2001, Finland established an open source National Biodiversity Database that compiles multiple data sets ranging from detailed environmental studies to observations of citizen scientists. This extraordinary access to information has allowed the city to measure numerous data points within various conservation area boundaries, including statistics related to the protection of individual sites and species.

Measured by several taxonomies, including vascular plants, birds, fungi, and pollinators, Helsinki has an unusually high biodiversity when compared to neighboring municipalities or to other temperate European cities and towns. Vascular plant species, for example, average over 350 species per square kilometer, as compared to Berlin and Vienna’s average of about 200 species. By embracing biodiversity within the structure of the city, not only is the importance of regional biodiversity codified into the general master plan, it is also embedded into the civic discourse of its citizens.

When it comes to where the next virus might emerge, Wuhan isn’t really that different from Washington, D.C. If the American model of over-indulgent suburban sprawl is the benchmark for individual success, we all lose.

Now is the moment to put the health of the planet before American values of heaven on a half-acre. Land use policies in the United States have just as profound an impact on the rest of the world as any movie out of Hollywood.

If we shift American values toward embracing denser, cleaner, and more efficient cities that drive ecological conservation—instead of promoting sprawl as a panacea for our current predicament—that may very well be our greatest export to humanity.
