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.

Architect of Sweden’s No-lockdown Strategy Insists It Will Pay Off – 05/07/20, The Financial Times
“Anders Tegnell, Sweden’s state epidemiologist who devised the no-lockdown approach, estimated that 40 per cent of people in the capital, Stockholm, would be immune to Covid-19 by the end of May, giving the country an advantage against a virus that ‘we’re going to have to live with for a very long time.'”
Since the earliest human settlements, the retail experience has evolved to meet the needs of the public. This evolution has taken us from rural markets to towns, cities, suburban shopping malls, big box mega stores, and, more recently, the Internet. But what will retail shopping look like once COVID-19 lockdowns are over and people return to the wild for their shopping experiences?
When all the dust settles, the post-lockdown era should provide a boost to downtown areas, in part due to newly unemployed but highly skilled restaurant and retail workers opening new businesses in downtowns where rent prices will trend downward.
The pandemic has left millions of highly skilled workers from the retail and food and beverage industries unemployed and eager to work. Many of these people are highly motivated to start their own businesses, creating an unparalleled pool of talent and potential entrepreneurial interest.
In a recent Forbes article, Bernhard Schroeder wrote: “27 million working-age Americans, nearly 14 percent, are starting or running new businesses. And Millennials and Gen-Z are driving higher interest in entrepreneurship as 51 percent of the working population now believes that there are actually good opportunities to start companies.”
Traditionally, fear of failure has held people back from starting a business, but with so many having their jobs swept away due to the pandemic, that fear is gone for many people, who realize they no longer want to rely on an employer for the rest of their careers, and instead want to take on the challenge of leading their own companies.
Downtown shopping districts will capture traffic from fading malls
Malls will struggle in the era of COVID-19. Being inside an enclosed bubble will not be the ideal situation for most shoppers for the foreseeable future. Morning Consult reports that 24 percent of U.S. consumers fear shopping in malls for at least the next six months due to the COVID-19 threat.
As an article about a newly reopened mall in Atlanta explains, the experience won’t be very welcoming in the near term. Play areas are roped off, water fountains covered, and stores are limiting the number of shoppers due to social distancing. Add in the inconvenience factor, and it’s clear why so many malls are facing a reckoning in the coming years.
As regional malls continue losing consumers due to changing shopping habits and fears of COVID-19, an excellent opportunity presents itself for villages, towns, and cities to regain their dominance as thriving centers for retail and entertainment.
Some factors to consider:
As Millennials and Empty Nesters seek to live, work, and shop in urban centers, medium-sized cities (100,000 to 200,000 population) are especially likely to benefit from this trend.
Small towns (10,000 to 20,000 people) located near large urban centers are also appealing to start-up retailers and restaurants that want to take advantage of their proximity to large, well-heeled populations and small towns’ affordable commercial storefronts.
New walkable town centers — planned with authentic urbanism and a variety of hospitality, employment and residential land use — can also ride the wave of Millennials, young families, and Empty Nesters who seek an exciting place to hang out.
Main Streets are already innovating
Main Streets have been reinventing themselves in a positive way during the past few decades, making them a more attractive alternative for retail shopping in the era of COVID-19.
These innovations include:
Updated master plans that undo blight caused by 1970s urban renewal plans.
Implementation of Downtown Development Districts, which offer marketing, promotions, special events, street cleaning, landscaping, flowers and private-sector levels of management.
Effective parking management, and construction of new parking lots and garages.
Investment in beautiful new streetscapes, public art, and street furnishings.
Reduction of crime, increased safety.
U.S. Main Street programs, which offers guidance to revitalize downtowns, and returns $36 for each $1 invested.
For Millennials, who seek more social experiences as opposed to the enclosed mall experience of their youth, Main Street experiences in their towns and cities are the perfect fit for their lifestyle.
While the larger portion of their income will go to experiences such as European travel or outdoor adventures, closer-to-home visits to a local brewpub or coffee shop in their town center make perfect sense.
Main Streets will provide new homes for mall stores
As malls close and online shopping grows, existing mall retailers will seek new locations near their former mall stores. In many instances, these venues include smaller downtown cores, which traditionally offer lower rents and, now, the safety of an open-air shopping experience.
The writing is on the wall for mall store operators, all of which leads to an economically-friendly, Main Street setting:
Malls depend on department stores to attract almost 50 percent of their shoppers and cannot operate without them, which is problematic for many reasons.
Many mall retailers have lease options allowing them to break their leases and leave the mall should key department stores close.
Department stores are losing market share, from a peak of 50 percent of all retail sales in the 1950s to 5 percent today.
Since the heyday of malls in 1992, department store sales have dropped from $230 billion to $140 billion and many department stores are close to bankruptcy.
Over 50 percent of regional malls are forecast to close by 2025 (Credit Suisse).
Retail and Office Space Will Move to Town Centers
The online shopping boom has made nearly obsolete many of the conventional large power center retailers offering products such as books, electronics, office supplies, sporting goods, and toys. The end result is the expected closing of millions of square feet of retail space.
Often, these centers cover typically 20-50 acres of prime real estate, which presents an opportunity. They can be converted into mixed-use town centers with medium density residential and commercial occupants.
The same can be said of suburban office parks, as even centers in blue-chip locations are facing high vacancies and declining rents as many major corporations are moving into city centers to attract top talent. Millennials find the suburban office parks boring, preferring to live and work in downtowns. These large office parks have an abundance of land and parking that can be retrofitted into walkable mixed-use town centers.
Challenges and opportunities for downtown shopping districts
When a national brand relocates from a mall environment to a town or city, they may initially receive a cold shoulder from city leaders and the community, who fear popular brands will end up killing their beloved Main Street’s unique charm.
Looking back at history, though, this thinking is inaccurate, as downtown shopping districts were filled with leading retailers and large department stores during their 1950s heyday. For long-term sustainability, a downtown should always offer the goods and services desired by its residents and workers, which may include popular brand names.
Zoning is another key battle. Cities must offer flexible form-based zoning to allow for medium-to-high densities of residential and commercial to be developed as walkable neighborhoods and business districts. Development standards should focus on requiring quality design and materials, rather than arbitrary minimal units per acre densities, minimal parking ratios, or suburban building setbacks.
Parking needs to be reconfigured to allow shoppers to pickup goods curbside.
Downtowns and open-air town centers are seen as safer from the pandemic than enclosed malls, because they offer:
Less-enclosed spaces, with more fresh air and direct sunlight.
The ability to walk on other side of street or block.
No elevators or escalators.
Fewer doors to enter.
Curbside pick-up of goods.
People enjoy visiting towns and cities to socialize and experience parks, urban life, including storefronts.
They visit to have an experience they cannot get through online shopping. And while visiting downtowns for entertainment and fun, many will walk by store fronts and be tempted to make impulse purchases from Main Street retailers.
Towns and small city landlords typically offer much cheaper rents than suburban malls, often more than 50 percent less, and also offer flexible lease terms: no minimum hours and less rigorous storefront and merchandising standards than mall leases. This type of accommodation will be more attractive to new entrepreneurs created from this pandemic.
The savings also are appealing to national retailers facing declining sales and mall leases that are too expensive.
How downtown Main Streets can ensure success
As we look to the future, and the economic recovery that will come once a vaccine is created and herd immunity is established, all signs point to the re-emergence of Main Street as the place people will want to do their retail shopping.
A new generation of entrepreneurs will be eager to start a new chapter in their life, and the suburban shopping centers are not going to attract them.
Well-designed town centers, with the type of social interaction sought by Millennials, young families, and Empty Nesters will be the new home for the boom in the years to come.
A few best practices for downtowns to apply:
Create a marketing strategy for a post-pandemic campaign.
Beautify the public realm through landscape, lighting, parking lots-garages, signage, streetscape, and storefront improvements.
Explore temporary commercial street closures to allow for open air dining and shopping spaces.
Modify zoning to allow first floor office and service business.
Require store fronts to maintain large clear glazing, sign bands, operating doors, and ceiling heights to allow for future retail or restaurant use.
Remove or reduce minimum retail and restaurant parking requirements in downtowns and new mixed-use developments.
Include generous 10-minute parking spaces to accommodate curbside pickups for restaurants and retailers.
Devise market-based business recruitment plans and resources to identify and attract new retailers and restaurants into the downtown.
Seek a balance of local, regional, and national retailers.
Apply flexible zoning to promote medium-density and high-density multi-family residential.
Implement market based master plans, form-based codes, and zoning flexibility to allow for retrofitting of underutilized shopping centers and office parks.
Robert Gibbs, FASLA, is president of the Gibbs Planning Group, which has advised and planned commercial areas in some 500 town centers and historic cities in the U.S. and abroad. Gibbs is a charter member of the Congress for New Urbanism, a lecturer at the Harvard University Graduate School of Design, author of Principles of Urban Retail Planning and Development, and co-author of eight books.
In a Zoom lecture sponsored by Harvard University Graduate School of Design (GSD), David Moreno-Mateos, a restoration ecologist and an assistant professor of landscape architecture at GSD, asked: “Are we ready to restore the planet?”
The trends on global biodiversity aren’t good. As humans degrade or destroy an increasingly large share of the Earth’s ecosystems, extinction rates have tripled in the past 100 years. “Vertebrate populations have declined 58 percent in the last 40 years,” Moreno-Mateos explained. Furthermore, local species richness has declined by 40 percent in most developed countries over the past 150 years.
Moreno-Mateos believes nature itself is a thing of great value. Nature provides an estimated $125 trillion of benefits in the form of food, water, medicine, and other resources through its ecosystems. Biodiversity is critical to ensuring the function and resilience of these ecosystems. To connect the dots: biodiversity is then central to clean air and water and the preservation of our food sources through seed banks, pollinators, and fisheries.
The challenge is that “ecosystem restoration is a long-term process.” In a review of scientific studies on some 3,000 restored ecosystems, research has shown that after 150 years, restored ecosystems are 70 percent less diverse and 40 percent less functional than undisturbed ecosystems.
Land-based ecosystems are made up of a diversity of animal, insect, fungi, and plant species, with specific carbon, soil, and water characteristics. There are specific levels of nutrients, including phosphorous, organic matter, and nitrogen. These elements all interact in particular ways. Given all the complexity, “ecosystem restoration has limited effectiveness.”
So this was perhaps the key message of Moreno-Mateos’ talk: the best approach is to not degrade incredibly complex ecosystems. There is still too much about their functions we don’t understand, and it’s nearly impossible to recreate their dense networks of interactions.
But if an ecosystem has been disturbed, Moreno-Mateos sought to find out: what happens over the long-term? What can be done?
Species diversity results in community composites. Think of a meadow, a community of plants that thrives together. There are interaction networks within those communities and between communities. A resilient meadow has a greater abundance of network interactions, with a higher number of “strong links” — “that is species that interact more strongly.” The same is true below ground. Amid soil communities, “the higher the complexity, the higher the functionality, and, likely, the resilience.”
For his own research, Moreno-Mateos started with the assumption that ecosystem degradation reduces genetic diversity. In southwest Greenland, Norse farmers settled two sites some 650 years ago. Archeologists discovered each village had about 100 people who farmed hay for cattle. To Moreno-Mateos, this seemed to be the perfect place to study the long-term impacts of ecological disturbance.
Examining an undisturbed site and a disturbed, former agricultural site, and looking at their above ground plant communities and below ground soil communities, Moreno-Mateos found “both sites had a similar amount of plant communities (35 species in the disturbed site and 34 in the reference site), but the compositions were totally different. In the disturbed site, one plant community dominated.” Moreno-Mateos also discovered the former agricultural sites had more nutrients because the Norse would add manure to the hay fields, which meant more nitrogen and phosphorous.
There was another key finding: the original, undisturbed site had more “mutualistic interactions.” The degraded site had more “pathogenic interactions.” This fit his hypothesis: “loss of biodiversity means more pathogens” and loss of function and resilience.
This was proven through the very different network interactions between plants and fungi in the soils in each site. In the formerly agricultural landscape, there were 15 plant species and just 37 fungi species, creating 62 links. In contrast, in the ecologically-healthy, undisturbed site, there were 12 plants and 76 fungi that created 148 links. This means networks in disturbed sites are more vulnerable to change.
Moreno-Mateos’ research could have implications for global ecosystem restoration. He believes restoration ecologists must “first understand how the complexity of ecosystems re-assembles over hundreds of years, and then find species that play critical structural and functional roles in the assembly process and use them in the restoration process.”
To increase the resilience of restored ecosystems at a more rapid rate, Moreno-Mateos called for sequencing whole genomes of species in recovering populations to understand their adaptation potential. This process would help identify populations of target species whose genomes have the best chance to adapt to ongoing global change.
The idea is to select species with critical ecological roles that come from populations with the highest adaptation potential and strategically insert them into recovering ecosystems. This process would involve finding populations of species in a landscape with high-functioning genomes and using those seeds to help restore ecological balance elsewhere.
Moreno-Mateos envisioned designing assemblages of high-performing plant communities and targeting them for tough environments in cities or for recovering forests or other ecosystems at a landscape scale.
“We need to imagine what landscapes will look like in 400 years.” Our future ecosystems must be “resilient to climate change, biodiverse, self-sustaining, provide ecological services, and last forever.”
Lithuanian Capital to Be Turned into Vast Open-air Cafe — The Guardian, 04/28/20

NYC Will Open up to 100 Miles of Streets to Pedestrians — Curbed, 04/27/20
“Under an agreement with the City Council, the de Blasio administration will open up at least 40 miles of streets in May, with the ultimate goal of 100 miles in the coming months. The undertaking will also roll out temporary bike lanes and expand sidewalks, he said.”
These tweets appeared on the Regional Transit Authority (RTA), New Orleans, and NOLA Ready Twitter feeds:

These messages bring to light the nightmare of those who depend on transit in order to maintain a steady job. They are facing a double crisis during the COVID-19 pandemic.
There are some of us who have easy access to work, because we do it from home at our laptops, but most aren’t so lucky. Many citizens must ride the bus or take other mass transit to earn a basic living. These are often the essential and frontline workers, those working in grocery stores, pharmacies, hospitals, supplying important city services such as trash collection and utility maintenance, and even bus drivers.
Many of these people are already located in Transit Deserts — areas with high transit demand and limited or no access. With bus services cut, people are crowded on to fewer buses. The current situation — which is not only limiting but also eliminating transit service — is exaggerating the existing transportation inequities in already underserved areas. The COVID-19 crisis is exposing how particular segments of our society are more at risk due to historical and structural inequality in many areas, including housing and employment but certainly transportation access.
The current responses to the pandemic also reveal ways to address transit access and some of the inequities this crisis has exposed. I have noticed more people walking and biking in parks and along streets. With the reduction of travel by automobile, this means fewer cars on the road and reduced carbon emissions, creating several health benefits, including cleaner air.
Importantly, the current situation also strengthens the argument that given certain conditions, increased numbers of people will readily give up car travel if they had alternatives or had to, or at least use them less, even in a place as automobile dependent as Texas, where I am making these observations.
It is most likely that once more people are again traveling to work, there still will be a need for social distancing, presenting a major concern for traveling on buses and other forms of mass transit.
Social distancing, brought on by the pandemic crisis, may be key to a solution for increasing transit in a catalytic fashion. If fewer people can be on a bus, then there must be more buses on each route just to maintain the base level of public financed mobility. More buses on a line means greater frequency and less wait time. Less wait time is proven to be a factor in increasing ridership.
When asked why they didn’t take the bus, given it took them straight to work, the majority responded that they didn’t want to wait at the bus stop. I then asked: if the bus came frequently would they take it? The reply was overwhelmingly yes, even if it meant transferring to another frequent line. This is true in most dense urban areas.
Most people are even willing to endure a longer ride time, if the wait time at the point of access is reduced. It can be reduced with frequently arriving buses that also prevent the overcrowding that usually happens, thus allowing people to maintain a safe distance apart. In my view, it is a win win, particularly if the medical cost of maintaining social distances is added on to the funding source for more public transit.
The severity of the Coronavirus pandemic means that things won’t ever get back to “normal.” For those who care about the environment and those in it, it is a time to rethink how we live and move about the urban landscape.
We can create mobility solutions that are equitable, environmentally sound, and protect our health. Of course, it only starts with putting more buses on the line. There is now an opportunity for creative thinking.
Maybe we can invest in on-demand vans, or “VIA” type services, which is a pay-on-demand van service that runs on a fixed route; and other smaller multi-passenger vehicles that are publicly subsidized and capture residents in neighborhoods and connect to frequent larger vehicles on major routes.
There is now an opportunity when people are appreciating the opportunity to take a walk and ride a bike and be healthy, adjusting to not being in cars so much of the time, appreciating clean air and the ability to just breath, and willing to make sacrifices for their neighbors, community, and country.
During times like these, those of us who are moved by problem solving must think outside of the limits of traditional transportation and step up to the challenges of creating an equitable society where there is mobility choice — and everyone has equal access to work, play, and the pursuit of life.

On April 22, 1970, 20 million Americans, which at that time was some 10 percent of the population, took to the streets during the first Earth Day, demanding greater protections for the environment and decisive action to improve human health and well-being. 50 years later, the movement is now global, with an estimated one billion participating each year. What role does collective action play in solving today’s climate and ecological crises? What role do landscape architects play?
Earth Day is a chance to pause, take stock of the planet that sustains us, and think and act beyond ourselves to reach the scale of the globe and all its inhabitants. Landscape architects are largely concerned with the “middle scale,” but Earth Day forces us to conceive of the planetary landscape, and what our role is in retrieving the Earth from its climate emergency status.
Our book Toward an Urban Ecology describes the potential of collective action at a landscape scale and gives many examples of digging in, showing up, ripping out, and gardening with your neighbors. At the same time, it’s important to keep focus on the more radical, insidious challenges in our carbon-intensive economy mapped out at a national scale in Petrochemical America, which depicts the American landscape as a machine for consuming oil and petrochemicals with profound impacts on ecosystems and communities.
I guess the lesson here is that on an individual level, we have to consume less. At a neighborhood level, we can work together to repair the landscapes in our immediate environs through community oyster gardening or invasive species removal in a patch of forest. And at a global scale, we have to radically and equitably decarbonize our economy and rebuild the wetland and intertidal landscapes disappearing before our eyes. Our installation at the Venice Biennale called Ecological Citizens bridges these scales of thought and action. Plenty to do!
What connections do you see between the COVID-19 pandemic and our climate and ecological problems? How are environmental and human health connected?
COVID 19 shines a spotlight on our health care system and existing social inequity. The pandemic is truly playing out as a human tragedy on so many levels. It also reveals the incredible and irreversible harm we are inflicting upon non-human species and our extreme interdependence on each other and the natural world.
Whether the virus was transmitted through a bat or pangolin, it’s a parable about the exploitation of “the other” that must stop. This April, 25 tons of pangolin scales were seized in Singapore, taken from nearly 40,000 of these endangered creatures. An estimated 2.7 million are poached every year. It boggles the mind.
On a positive note, one can imagine our “stay at home” behavior, which is intended to curb the pandemic, has the unintended consequences of lowering our personal carbon footprints; and leading us to care for each other more, make time to mend the landscapes in which we live, and prioritize the basics of happiness and survival — food, shelter, clean water, clean air, neighbors, family, and the core of what matters to you.
You founded SCAPE in 2007. Your office’s stated mission is to “enable positive change in communities through the creation of regenerative living infrastructure and public landscapes.” What is regenerative living infrastructure and why do communities need it?
Today’s society faces compounding risks: a climate emergency, increasing social and income stratification, and a biological apocalypse termed “the sixth extinction” by Elizabeth Kolbert in her 2014 book of the same name. Together, these forces are rapidly tearing at the fabric of our entangled social and natural worlds. In every SCAPE project, we identify the capacity of design to repair that fabric and regenerate connections over time.
The aim is to not just deliver built work, but envision a program that begins to generate new ties between communities working in, living in, understanding, and loving the landscapes that sustain them. This could take the form of unlocking sediment trapped upstream to nourish protective bay landscapes and cushion the impacts of extreme weather and sea level rise.
For decades, infrastructure has been constructed as “single-purpose,” often designed by engineers to isolate one element of a system and solve for one problem. For example, on Staten Island, during Superstorm Sandy, a levee designed to keep water out was overtopped, resulting in a “bathtub effect” of trapping water inside a neighborhood rather than keeping it out. People perished because of this catastrophic failure. In many places, metal bulkhead walls are being raised in anticipation of sea-level rise only to block drainage during major rain events, flooding adjacent blocks.
Regenerative landscape infrastructure helps to maintain the structure and function of ecosystems embedded in the built environment, accounting for complex systems. This has been the organizing mission of SCAPE: to bring holistic, landscape-driven, and time-based thinking into the places we inhabit.
Through Living Breakwaters in Tottenville, on Staten Island in New York, SCAPE created a layered approach to ecological and social resilience, including oyster habitat restoration on a series of near-shore breakwaters. Working with communities in Boston, SCAPE has developed visions for a more resilient Boston Harbor and Dorchester neighborhoods. What are the benefits of these resilient landscape approaches?
The resilience benefits of these projects are clear. We can’t just look at one facet of the future: We have to synthesize how climate shocks and stressors compound each other. Extreme heat will increase drought and poverty. Extreme hurricanes will increase long-term rainfall projections used as a base for design efforts. How will these shocks and stressors combine to impact people and shape our future?
Robust, intact landscapes can’t do everything, but they can absorb a range of intersectional challenges and create immense protective value. Part of SCAPE’s approach is to begin to address the “sixth extinction” in the intertidal zone, restoring landscapes and habitats for marine critters that could be a lifeline to the future. We not only envisioned the Living Breakwaters project. Over many years, we navigated a federal, state, and local regulatory and budget environment to make it happen. We have a unique perspective on how to advance these kinds of projects despite many roadblocks and challenges.
Our team just completed a long-term vision for the rapidly eroding Barataria Basin in Louisiana with an array of collaborators. This project combines marsh creation with bottomland reforestation, sediment diversions, and related landscape restoration and job creation strategies. A healthy and bountiful landscape means better economic opportunities for a wider range of people, rebounding shellfish and fisheries, and a coastal landscape that can absorb and adapt to a range of climate risks on the immediate horizon.
The Chattahoochee RiverLands is a vision to reconnect Metro Atlanta to its seminal river, building on a decades-long legacy of community planning in collaboration with the Trust for Public Land, Atlanta Regional Commission, Cobb County, and the City of Atlanta. It’s a radical effort to stitch together a historically fragmented public realm along a primary conduit – 125 miles of trail winding along the Chattahoochee that showcase the river’s ecology, history, and link into ongoing restoration and education efforts.
Rivers have such power to bring people together, link up disjointed places, and bring life and mobility into cities. For this project, we cut through red tape, charting a path of access through a mosaic of public and private lands. The overall vision was grounded in over 80 stakeholder and community sessions and events like “river rambles,” educational outings for focus groups to provide hands-on learning experiences.
Beyond its physical footprint, the goal of the RiverLands is to raise public awareness, improve connections and access, address a long legacy of environmental racism, expand mobility for underserved communities, and build on a strong regional legacy of water resource conservation and protection.
This effort is a testament to open and inclusive design processes structured to empower residents and to shift from conceiving design as a “master” plan to a method of workshopping and co-creating with constituents. Advanced floodplain warning systems and sensors can be integrated into these linear landscapes to ensure public safety.
Lastly, you are also a Professor at Columbia University School of Architecture, Planning, and Preservation (GSAPP), where you are director of the Urban Design program. What have you learned from your students – the next generation of leaders – about how to solve our challenges? What new ideas have really astounded you?
Over the past five years, I’ve done a series of studios focused on Water Urbanism – global studios to uncover how water, climate, and migration patterns combine to shape the future of cities. I’ve learned so much from this endeavor and working alongside my incredible co-teachers Geeta Mehta, Dilip Da Cunha, Thaddeus Pawlowski, Julia Watson, and others. We’ve traveled to Amman and Aqaba, Jordan; Rio de Janeiro and Sao Paulo, Brazil; Can Tho, Vietnam; and four cities in India: Kolkata, Madurai, Varanasi and Pune, among others.
From our collaborators and students, I’ve learned that excellence emerges in the space between people – in open dialogue, hard work, and collaboration among people with diverse and international backgrounds with a shared purpose.
A few years back, I hosted “Water and Social Life in India,” a panel at the ASLA Conference on Landscape Architecture with Geeta, Dilip, and Alpa Nawre. This session captured some of the big lessons for me. Over the years, we have learned water is not an abstract “issue” to be solved. To embrace a water-resilient future, we have to learn from past practices and small communities managing and communicating with each other. Designing with water is not just about adapting to changing conditions – it is also crucially about fostering forms of social life, maintenance, and care.
In Tainan, a city of 1.8 million on the southwest coast of Taiwan, a defunct shopping mall has been transformed into Tainan Spring, an urban lagoon park. This ingenious new public space, which reuses remnants of the mall’s concrete parking garage, is at the heart of an ambitious effort to bring people and nature back to the waterfront of Taiwan’s oldest city. Commissioned by the urban development bureau of the Tainan city government, the new 581,000 square foot (54,000 square meter) landscape forms a green axis with a kilometer-long stretch of Haian Road that has been redesigned for pedestrians.
According to project designer MVRDV, a Dutch architecture and urban design firm that led a multidisciplinary team including Taiwanese landscape design firm The Urbanists Collaborative, Tainan’s network of waterways have enabled the city’s marine and fishing industries since the 17th century. But in the 1980s, the city began to over-develop its waterfront. The ChinaTown Mall was constructed on top of the old harbor next to the Tainan Canal. Decades later, as the abandoned shopping center became a “drain on the vitality of downtown,” the city developed plans to turn it into a destination park.
The Tainan city government required that the old mall be deconstructed and its concrete “meticulously recycled.” Given the embodied carbon in concrete, the decision was made to also reuse a level of the underground parking garage as part of the structure of the $4.7 million sunken park.
Concrete structures have been mostly integrated with a new pedestrian promenade that loops the park. Below the promenade, nooks have formed that will soon host small shops and restaurants.
MVRDV created multiple layers to create a sense of history and place. Within the curvilinear lagoon, pillars of the garage structure jut out, creating a shopping mall-version of a Roman ruin.
Remnants structures provide watery play spaces and shade. One part of the park contains a glass floor that offers a glimpse deep into the old infrastructural layers below.
The lagoon is planted with multiple layers of plants and trees, which are expected to grow over the next few years into a stylized jungle. The plant life will cool and shade gathering areas, playgrounds, and a performance stage.
The lagoon itself is also designed to be responsive to the environment. “Water levels within the lagoon rise and fall in response to the rainy and dry seasons,” MVRDV states. During Tainan’s steamy summer, mist sprayers will help reduce ambient air temperatures.
“People can bathe in the overgrown remains of a shopping mall. Children can swim in the ruins of the past,” said Winy Maas, founding partner of MVRDV. “How fantastic is that?”
The team’s renovation of Haian Road reduced traffic to one lane in each direction. The new road uses pavers to create a uniform identity and incorporates more of the jungle plant palette. Maas added that “Tainan is a very grey city. With the reintroduction of the jungle every place possible, the city is reintegrating into the surrounding landscape.”
