“We asked ourselves — if we could move 1,200 trees through a city center for over 100 days, then imagine what else we could do,” said Bruno Doedens, a Dutch landscape architect and land artist, who created the wonderful Bosk public art installation in the city of Leeuwarden with his collaborator, the late Joop Mulder.
Over 100 days this summer, teams of volunteers pushed large and small trees along a 2.1-mile (3.5-kilometer) route as part of Arcadia, a triennial arts festival in Friesland.
The organizers explain that the installation moved in stages through neighborhoods on weekdays, led by traffic controllers and captains, “so the forest decreased in one place while growing somewhere else.”
Streets that had few trees temporarily became lush forests, changing the character of communities, significantly cooling air temperatures, and slowing the pace of life. The Guardian reported hotels and businesses also benefited from the traveling forest, though some residents were upset by having to park elsewhere.
The trees were planted in more than 800 wooden containers that were then loaded into wheeled carts. They included more than 60 native species, such as alder, ash, elm, maple, oak, and willow.
The Bosk team labeled each tree with a QR code, so residents could learn more about the species. Soil sensors also alerted the team when any tree needed more water.
Just planting 1,200 trees around the city would have perhaps been easier but “would have had less impact than a moving forest,” Doedens said. The logistical challenges of transporting trees through traffic in a coordinated way “forced citizens to really face the effect of a forest in the city center.”
“The success of Bosk lies in the combination of radical imagination and mobilizing large communities of people,” he argued. The residents of Leeuwarden can now imagine “a new relationship with nature — one based in the idea of enriching the planet rather than polluting and destroying.” With rising urban temperatures, a new relationship rooted in nature will become increasingly important.
The message of the interactive public art work was reinforced through a broader immersive program that included a “summer school for Leeuwarden neighbourhoods, a Bosk news program for primary school pupils, and a whispering garden full of inspiration,” the festival organizers write.
In his essay Planet Paradise, Doedens argues that collective art projects like the walking forest can change mindsets and spur on greater climate action. They inspire communities to re-imagine what is possible. Designers and artists therefore play a critical role.
“Allow all creative minds from all cultural disciplines – music, dance, theater, poetry, literature, film, architecture, visual arts – together with scientists and pioneers from the practice to dare to dream and think big and even bigger. Give them room for imagination and intuitive thinking to radically reassess our current values and our actions. Allow them to develop new languages that touch our hearts and create new stories and images that help us realize we are walking in the mist, that seductive illusions intoxicate us, and that we need to change radically.”
Landscape architects and artists everywhere can create “new stories that reassure us in a playful way that we can reverse the negative effects of our treatment of the Earth into something positive. They must also be optimistic, empathetic, hopeful, and challenging without being blind to the sizeable and far reaching task ahead of us.”
The Bosk installation ended August 14, and the organizers have since found permanent homes for the traveling trees throughout the city, with many planted in underserved communities.
Led by climate leaders in the field of landscape architecture, ASLA is developing a profession-wide Climate Action Plan
ASLA has announced it is developing its first Climate Action Plan for the U.S. landscape architecture community. The ambitious plan seeks to transform the practice of landscape architecture by 2040 through actions taken by ASLA and its members focused on climate mitigation and adaptation, ecological restoration, biodiversity, equity, and economic development. The plan will be released at the ASLA Conference on Landscape Architecture, November 11-14, 2022, in San Francisco, CA.
The ASLA Climate Action Plan is led by a five-member Task Force and 16-member Advisory Group of climate leaders from the landscape architecture profession.
The diverse, intergenerational Task Force includes climate leaders at different stages of their professional life.
“Landscape architects are leaders in designing solutions to the climate and biodiversity crises that also provide multiple environmental, economic, social, and health co-benefits. ASLA purposefully included both established and emerging climate leaders in this critical Task Force, which will shape the profession far into the future,” said Eugenia Martin, FASLA, ASLA President.
Task Force members include:
Chair: Pamela Conrad, ASLA, PLA, LEED AP, Principal, CMG Landscape Architecture, and Founder, Climate Positive Design, San Francisco, California
Conrad built Climate Positive Design into a global movement with the goal of ensuring all designed landscapes store more carbon than they emit while providing environmental, social, cultural, and economic co-benefits.

The goals, objectives, and action items of the plan are also shaped by a Climate Action Plan Advisory Group of 16 diverse climate leaders, who are based in 12 U.S. states and two countries and in private and public practice and academia. The Group consists of nine members who identify as women, seven as men, two as Black, four as Asian and Asian American, one as Latina, and one as Native American.
“ASLA believes equity needs to be at the center of climate action, because we know climate change will disproportionately impact underserved and historically marginalized communities. It is important that the group guiding the Climate Action Plan and the future of the profession mirrors the diversity of the landscape architecture community and its breadth of educational and practice areas,” said Torey Carter-Conneen, ASLA CEO.
Advisory Group members include:

In 2021, ASLA joined with Architecture 2030 to call for the landscape architecture, planning, architecture, development, and construction professions to reduce greenhouse gas emissions in their projects and operations by 50-65 percent by 2030 and achieve zero emissions by 2040.
The need to rapidly adapt to climate change has rightfully taken center stage. But the connections between climate change and stormwater management are often overlooked. Climate change impacts the hydrological cycle by increasing water scarcity and the frequency and intensity of flooding while contaminating waterways. Better managing stormwater is key to managing water resources and protecting our safety and the health of our environment.
Unfortunately, stormwater management is usually portrayed as a purely technical issue to be solved at the site. Instead, stormwater management systems should be valued as critical green infrastructure that provides design opportunities and are foundational to giving form to the broader built environment.
While stormwater management may not be sexy, it is vital to understand and integrate as part of larger efforts to protect our ecosystems and environment. The book Working Water: Reinventing the Storm Drain by landscape architecture and planning firm Wenk Associates argues challenges to “any city’s water supply and urban stormwater management can be addressed, in part, by changing how we manage our urban water resources as part of systems that employ the widespread use of natural technologies.” The firm, founded by landscape architect William Wenk, FASLA, has incorporated stormwater into the design of built environments and landscapes in the West and Midwest for over 35 years.
Projects in the book exemplify how stormwater, generally considered a nuisance, can be managed and integrated as a resource in the design of landscapes, making communities more livable as well as restoring ecological function and health. The selected projects range from built work early in the office’s practice to contemporary projects that explore the integration of function and beauty in managing stormwater at various project scales — from a small rain garden outside their early office in Denver to restoring the natural functioning of the Los Angeles River. In addition to cataloging projects, the author thoughtfully reflects on lessons learned, revealing both successes and failures as they suggest new approaches to create “the next generation of stormwater infrastructure, resulting in healthier urban and natural systems, making our cities better places in which to live.”
Wenk himself outlines his trajectory from a boy growing up on a farm in Michigan, to his foundational undergraduate studies in landscape architecture at Michigan State University, his observations about arid environments revealed while traveling across Europe and North Africa, and the influential work of artists, writers, and thinkers he explored during graduate studies at the University of Oregon. These experiences combine to inform the theoretical foundations for his life’s work.
He also shares his early career lessons regarding the value of urban green infrastructure that were strengthened while working closely with civil engineers. These professional experiences ultimately led to the founding of his practice in Denver, Colorado. Wenk desires to “reinvent the storm drain,” a metaphor for “expanding — down to the most basic details — the components of stormwater systems to invent new strategies for effective stormwater controls, and to promote the restoration of the natural functions of urban waterways in ways that add beauty and value to the urban landscape.”
The first part of the book explains the close relationship of water resource management to culture and technology and clearly describes the impacts of urbanization on the water cycle and the land. Explaining how positive aspects of both ancient and contemporary water management systems can be integrated to address contemporary issues of water scarcity and improve water quality, the book sets the stage to examine how urban water resources can be better planned and designed. Ultimately, successful projects restore the function of ecological systems while creating meaningful places for people to gather.
Then, the book provides a carefully curated selection of Wenk Associates’ projects that exemplify what is meant by “working water.” The scale, type, and complexity of the highlighted projects vary greatly from small site design to large river corridors. Each of the case studies, which cover sites, districts, and corridors, demonstrate the rigor of the designers’ intent. Each projects’ context, vision, design strategies, constraints, and results are thoughtfully communicated with clear jargon-free narratives, diagrams, renderings, and attractive photographs of the built work.
The third part of the book reviews the critical factors leading to the success of Wenk Associates’ built works, along with lessons learned about legal, financial, and other challenges involved in implementing natural technologies, and the profession of landscape architecture’s involvement in integrating “multiple values and functions into the city’s infrastructure” and communicating “those values to affected communities.” The lessons go further than most books on stormwater do by calling for incentivizing district-scale stormwater control systems, identifying barriers to implementations of natural technologies, and calling on practicing professionals and the public to be advocates for change.
Simultaneously, the scope of the book has limitations. Because this is a monograph, Working Water thoughtfully represents the experiences and philosophy of just one firm.
Missing from Working Water is also a stronger acknowledgement that underserved, historically marginalized communities are disproportionately hurt by the mismanagement of stormwater and that residents of these communities can play a greater role in designing a healthier and more livable environment.
The Menomonee Valley Redevelopment is an example that intentionally enriched underserved neighborhoods in Milwaukee by creating over 1,400 jobs, connecting neighborhoods with a new network of streets and green spaces, and providing access to a healthier and a cleaner river. Surely, this project included community input during the design processes to achieve these beneficial results. However, the residents and the role they played in this process are not given the prominence they deserve.
Working Water is a needed addition to the body of literature on how to integrate designed green infrastructure with stormwater management to create more livable cities for a couple of reasons. It addresses issues specific to the temperate Midwestern climate of the savanna and steppe ecosystems, while most books focus on the more humid environments of the East and West coasts. It also contributes examples of beautiful projects that demonstrate regionally appropriate responses from the drumlin-inspired landscapes of Wisconsin to the semi-arid grasslands of the Colorado Rocky Mountain Front Range.
Working Water is intentionally written as an educational resource for students, decision-makers, regulators, municipal staff, designers, developers, and community advocates. A pleasant surprise included at the end of the book is a “working water glossary” that provides the reader with a general understanding of the definitions of terms and concepts used in the book.
Wenk Associates were early leaders in the integration of stormwater design. Their work has been so successful, it is now considered common in the practice of landscape architecture. The functional requirements of successful stormwater management are so well integrated in each project that the unprecedented nature of the designs may be overlooked.
The monograph is written similarly. It is humble; it is not flashy and does not use fancy words. It offers straightforward yet beautiful graphics and diagrams with no enigmatic collages; just solid, well-crafted, thoughtful work.
Like Ian McHarg’s layering process, the incorporation of stormwater management has been so integrated into landscape architecture that it is unrecognized when done well. This collection of completed projects when assembled as a monograph, may seem simple, as though anyone could do it. But don’t be deceived, Working Water: Reinventing the Storm Drain demonstrates how Wenk Associates makes the messy and difficult work of envisioning and implementing a complex project look simple, clean, and elegant, with a vision for the future.
“It’s not good enough to just be active designers, we also need to be influencing policy upstream,” said Barbara Deutsch, FASLA, CEO of the Landscape Architecture Foundation (LAF), during the kick-off of Grounding the Green New Deal, a day-long summit held at the National Building Museum (NBM) in Washington, D.C. Landscape architects can “create a feedback loop in which we test designs and overcome barriers,” advancing climate, water, and infrastructure policy through innovative projects.
In 2020, LAF, the University of Pennsylvania, Columbia University, ASLA, and the Council of Educators in Landscape Architecture (CELA) launched a collective, open source Green New Deal Superstudio focusing on how to plan and design the key goals of the Congressional legislative proposal H.R. 109, which are jobs, justice, and decarbonization. Some 180 universities, 3,000 students, and hundreds of practitioners submitted 670 projects. Of these, 55 projects have been highlighted by Superstudio curators, and many were featured in an exhibition at the NBM during the summit.
In a lecture to introduce the first panel, Billy Fleming, ASLA, the Wilks Family Director at the McHarg Center at the University of Pennsylvania, gave an introduction to the broad Green New Deal agenda, which was introduced in Congress in 2019. The agenda was seen as a criticism of the economic recovery package passed under the Obama administration, which was viewed as “too targeted, too Wall Street, and only one-time funding,” Fleming said. The economic havoc wrecked by the market collapse of 2008 was viewed by many liberals as a “crisis wasted.” The Green New Deal outlined an ambitious vision for addressing climate change while also tackling deep-rooted inequities in American society.
Like the original New Deal from the 1930s, which was a response to the Dust Bowl and Great Depression, the Green New Deal would yield thousands of public projects that would reshape communities. But in contrast to the original New Deal, which was not equitable in its distribution of public funds and reinforced the racist Jim Crow-era patterns of disinvestment in Black communities, the Green New Deal would be “more collaborative” and focused on lifting up long marginalized communities.
At the start of a wide-ranging panel discussion, Fleming argued that “carbon is mostly a technical problem.” Landscape architects, planners, and architects can’t focus solely on decarbonization, with “life the same afterwards.” Instead, he and other supporters of the Green New Deal argue that decarbonization should serve a broader economic and social transformation. Solving climate change can be connected to improving the quality of housing, creating new local jobs, and forging a more equitable society.
Nikil Saval, a Pennsylvania State Senator who represents Center City, Philadelphia, said the intersections of all these issues can be found when you “turn on your lights or stove.” Because of “historical redlining and disinvestment in Black and brown communities, many homes in these communities lack insulation and are in disrepair. As a result, the energy needed for lighting, heating, cooling is much more expensive.” Saval said this inequality in the end-use of energy mirrors an unjust “political economy of gas infrastructure” that also disproportionately impacts communities of color.
He argued that communities need to instead “attack the role of racism and inequality” in the current energy infrastructure while investing in energy efficiency in low-income communities and affordable renewable energy. Otherwise, a new clean energy system may simply reinforce many of the injustices of the current fossil fuel-based approach.
Colette Pichon Battle with the Gulf Coast Center for Law & Policy was displaced by Hurricane Katrina. The disaster changed the trajectory of her legal career, and since then she has focused on environmental and climate justice in Louisiana, Mississippi, and other southern states.
Her organization and others in 13 southern states launched the Red, Black, and Green New Deal, an initiative that aims to tackle the drivers of climate change — economic and social inequality — and their impacts on communities, rather than focusing on “invisible atmospheric changes.”
The current economic system that leads to environmental and climate damages and injustices must be the focus of climate action efforts, Pichon Battle argued. For example, post-Hurricane Katrina, many cities in Louisiana were submerged under water for years. An incredible amount of trash accumulated and was eventually moved into landfills. Those landfills now form the foundation of new housing subdivisions marketed to low-income Black residents. “Those landfills are going to go under water again at some point and become toxic. Those Black folks marketed to weren’t just happened upon but targeted.”
“We need to be careful about talking about climate justice at a high level; it’s easy to decouple the issues from humanity,” argued Bryan Lee, another speaker on the panel, an architect and founder of Colloqate Design. “If you are talking about it at a high level, it means you don’t know your community. You need to know the people to know the climate impacts.”
Linda Shi, a professor of urban planning at Cornell University, asked everyone in the audience the question: “Who is part of the resilient future? Who makes space for others’ resilience dreams?” She argued that in any discussion about climate change, “we must center equity or it’s not about equity.”
She added that one challenge is that many engineering professions involved in building new climate infrastructure “have never been trained to deal with social issues.” Furthermore, governments and the private sector are more focused on reducing risk and legal liabilities with new infrastructure. “These legal concerns are different from justice, equity, and creating a sense of place.” This is where planners and landscape architects, who are skilled in equitable community planning and design, can help.
The Infrastructure Investment & Jobs Act created enormous opportunities for communities to improve their park, water, and transportation infrastructure. $50 billion has been allocated for improving water infrastructure alone, with 20 percent of that for water efficiency and reuse.
For Katherine Baer with River Network, the bill is a “transformative moment” and creates opportunities to design green infrastructure to achieve greater water equity. “We believe in connecting communities to their rivers, centering rivers in their life. In the built environment, there are too many buried rivers, creeks, and culverts. And these buried rivers impact some communities more than others.”
Anne Whiston Spirn, FASLA, professor of landscape architecture and planning at MIT, highlighted the ways landscape architects can empower underserved communities, address injustices, and increase climate resilience.
When her father took her to the March on Washington in 1963, “her life was transformed.” The march helped hone her life-long passion for “civil rights, environmental action, and beauty.” However, studying ecological design with Ian McHarg at the University of Pennsylvania, she found design academia at the time was “deaf to civil rights.”
Beginning 40 years ago, Spirn began partnering with communities through the West Philadelphia Landscape Project. White flight had led to disinvestment, but Spirn sought to keep people in cities by improving their environmental health and beauty. Realizing that “no one was going to pay me for this work,” she left private practice and took a job in academia. Using her salary she helped “communities who didn’t know they needed a landscape architect.” Through her “action research” approach, Spirn helped communities improve their landscape literacy. With the founding of her project, her goal was to “improve the natural environment and racial justice.”
She found that in low-income Philadelphia communities there is a lot of vacant land, which is almost always in the floodplain and often on buried streams. While she couldn’t convince the city government in the 1970s and 80s, she called for transforming those vacant lots into green infrastructure to manage water. She started partnering with middle school students to discover the communities’ environmental history. “I learned that landscape literacy could change the future. We need to empower youth. These kids are brilliant.”
Spirn and the West Philadelphia communities were eventually vindicated when the city reached more than a decade ago out to discuss its then-nascent Green City, Clean Waters plan. But she is now concerned all the green infrastructure improvements that have occurred in West Philadelphia as a part of her advocacy efforts are “catalyzing speculation and gentrification.”
She urged the audience to “think five to ten years ahead to the possible displacement impacts of your vision.” Any improvements in community green infrastructure should be coupled with “education, jobs training, affordable housing, and community land trusts.”
This 16-acre Atlanta Park Was Built to Flood — 01/28/22, Fast Company Design
“[Atlanta] didn’t just want to replace low-lying flooded homes with a low-lying flooded park. They worked with HDR on a design that would turn the empty acreage into a thriving public space that could also serve as an engineered drain, safely taking in the water during heavy storms and gradually releasing it underground. The park is designed to flood—and protect the surrounding neighborhood.”
Transportation Dept. Outlines Plan to Address Rising Traffic Deaths — 01/27/22, The New York Times
“‘Fatalities among pedestrians and bicyclists have been increasing faster than roadway fatalities overall in the past decade, which has a chilling effect on climate-friendly transportation options such as walking, biking or taking public transportation,” the report said. ‘To unlock the climate benefits of those modes, we need road and street systems that feel safe and are safe for all road users.'”
5 U.S. Cities Where Bike Commuting Is Booming — 01/26/22, Bloomberg CityLab
“A new report from the League of American Bicyclists traces how long-term planning and infrastructure investments allowed some cities to grow their share of bicycle commuters.”
Decades of redlining and urban renewal, rooted in racist planning and design policies, created the conditions for gentrification to occur in American cities. But the primary concern with gentrification today is displacement, which primarily impacts marginalized communities shaped by a history of being denied access to mortgages. At the ASLA 2021 Conference on Landscape Architecture in Nashville, Matthew Williams, ASLA, with the City of Detroit’s planning department, said in his city there are concerns that new green spaces will increase the market value of homes and “price out marginalized communities.” But investment in green space doesn’t necessarily need to lead to displacement. If these projects are led by marginalized communties, they can be embraced.
For example, efforts to enhance the Dequindre Cut in Detroit by transforming it into a 2-mile-long greenway were rooted in community needs and therefore have been supported. While the planning and design work by SmithGroup on the greenway corridor has led to positive economic impact, including growing nearby entrepreneurship and visitor engagement, it also expanded open space, expanded community development, and lifted up local graffiti artists. “We allowed the graffiti to stay and created canvases for more to come. It’s an avant-garde form of historic preservation, and a way to activate a latent, forgotten place.”
Another project is Ella Fitzgerald Park, in the Fitzgerald community, one of 10 key neighborhoods where the planning department has focused housing, park, and economic development investment. Given the neighborhood is experiencing high levels of bankruptcies and foreclosures, many remaining homeowners in the neighborhood can’t sell their homes. Instead of seeing a new community park and greenway designed by landscape architecture firm Spackman, Mossop, and Michaels and built by the city as a gentrifying force, it was welcomed as a safe place for children to play. “It was a needed change,” Williams said.
The Joe Louis Greenway, named after the famous athlete, spans 27.5-miles from downtown Detroit to Dearborn, once a segregated Black city. A “vision of inclusive design, the project is a form of green reparation,” Williams argued. The city has overlaid where redlining had the most destructive impact in Detroit and surrounding communities and has used green amenities to undo part of the damage. “We can focus on those red areas on the redlining maps, transforming them into productive, innovative, and ecological areas.” Planning and design efforts with SmithGroup included significant community engagement. Strategic green spaces, rooted in community desires, are one of “our best tools to address the mistakes of the past.”
Diane Jones Allen, FASLA, director and professor of landscape architecture at the University of Texas at Arlington and current fellow at Dumbarton Oaks, received a 2020 research prize from the SOM Foundation for her work, Reclaiming Black Settlements: A Design Playbook for Historic Communities in the Shadow of Sprawl. Her research has involved mapping Black Freedmen’s communities across Texas and included seven research projects in the Dallas / Ft. Worth area. Along the Trinity River, Allen has been immersing herself in “the bottom lands, the industrial lands” where many Black communities made their home. Despite the long-term environmental justice issues, these communities are still facing displacement pressures. “Riverfronts are hot right now, the place to be,” she said.
The existing community isn’t reacting negatively to Harold Simmons Park, a park planned on the Trinity River by Michael Van Valkenburgh Associates because it would create “healthy social spaces along the river.” To ensure housing prices in Black communities near the park don’t go up, a development corporation linked with a local church is “getting ahead of the curve and stabilizing and renovating homes.”
Another community down river, the Garden of Eden, founded by a Black family in 1881, has been impacted by concrete companies that dug industrial gravel pits along the river. Once leases on the land ended, the companies were supposed to fill in those gravel pits but never did. So the community is “reclaiming those pits through green infrastructure, creating recreational spaces.”
And at the last of the seven sites studied along the river, Joppa, a historic Freedmen’s town, there is the Joppee Lakes project, the site of a railroad and concrete plant which is being re-imagined as a stormwater solution for downtown Dallas. The Army Corps of Engineers turned the site over to the City of Dallas, which is in turn working with Black community there to revamp the Honey Springs Branch Park surrounding the lake as a community hub with green infrastructure that can handle both sewage treatment and provide recreation.
To avoid green gentrification, Allen said it’s key to “understand the history of each place. Design has to be grounded, and history is really powerful.” Black Freedmen’s communities along the Trinity River have created a community roundtable and are “envisioning the future together.” They are sharing “funding and grant sources, and talking about the issues.” Freedmen’s town groups are also “linking green spaces, creating a trail that will connect them all.” They are “very smart about the politics and policy and the air quality issues around transportation and cement plants.” Landscape architects can work with communities like these to help them “articulate the issues” and “promote and enhance connections with each other.”
Boston has invested $5 million to re-imagine Frederick Law Olmsted’s Franklin Park in Boston’s Dorchester, Jamaica Plains, and Roxbury neighborhoods. A team led by landscape architecture firm Reed Hilderbrand is spearheading the action plan effort and includes MASS Design Group, which is focusing on the “city edge’s and neighborhood connections,” and Agency Landscape + Planning, which is focusing on public engagement, planning, and programming. According to Sierra Bainbridge, ASLA, a landscape architect and senior principal with MASS Design Group, her organization is seeking to answer questions like: “Can we connect present and future generations to the park? Can the surrounding neighborhoods benefit from the procurement process for a redesigned park?”
Bainbridge argued that park’s ill-conceived boundaries are keeping many people out. The edges, which are “prohibiting access,” include 3-4 lane streets with no lighting for crosswalks. There are also no local businesses along the park, so if food trucks aren’t there, visitors need to bring in their own food and drink. “There is a huge opportunity to increase connections between the park and local community, particularly through large events.”
While planning and zoning changes need to happen to grow local business presence around the park, Bainbridge said procurement is also a powerful tool for increasing community engagement with the revamped Olmsted park. Looking to MASS Design Group’s work in Rwanda as a model, she said training and hiring local artists, masons, and workers was key to creating a sense of ownership around the organization’s community healthcare projects. “The question for many was ‘who is this project for?; we showed them that it is for them.” As a result, community members who worked on the project began to trust in the mission and started going to the care center and hospitals.
In the same vein, Franklin Park can create opportunities for local artists and workers. There is some flexibility in Boston’s procurement procedures if the amounts are under $10,000. “There is potentially a way to also phase larger projects in smaller amounts” to give more local businesses and artists chances to bid. As part of the project, the team is also training small minority- and women-owned businesses to take advantage of these opportunities. “Training costs less than 10 percent of the project, but the impact is multiplied throughout the community. Training is embedded in the plan.”
Clients are looking to landscape architects to provide nature-based solutions to climate impacts, with street trees, bioswales, and native, drought-tolerant plants in high demand.
ASLA has released its first national survey on demand for landscape architecture planning and design solutions to climate change. 563 landscape architects, designers, and landscape architecture educators in the U.S. responded to the survey in October 2021.
Nationwide, demand for planning and design solutions to climate change has increased over the past year. 77 percent of landscape architects and designers responding to the survey experienced at least a 10 percent increase in client demand for these solutions in comparison with 2020. And, of these, 38 percent of landscape architects and designers experienced more than a 50 percent increase in demand over the past year.
According to the survey results, city and local governments are the foremost drivers of demand for climate change-related planning and design projects. Non-profit organizations, state governments, and community groups, which may or may not be incorporated non-profit organizations, are also key drivers of demand.
Clients are concerned about a range of climate impacts, but are most concerned with:
Increased duration and intensity of heat waves
Increased intensity of storms
Increased spread and intensity of inland flooding
Loss of pollinators, such as bees and bats
Changing / unreliable weather, or “weird weather.”
The survey finds that landscape architects are also actively educating public, commercial, and residential clients about the importance of investing in more climate-smart practices.
Nationwide, 65 percent of landscape architects and designers surveyed are recommending the integration of climate solutions to “all or most” of their clients. They are creating demand for more sustainable and resilient landscape planning and design practices through “advocacy by design” approaches that persuade city, local government, and other clients to update policies and regulations.
To increase community resilience and reduce greenhouse gas emissions, landscape architects are planning and designing infrastructure at all scales – from the city and county to district, neighborhood, and site.
The top community-wide infrastructure solution clients are requesting is stormwater management to reduce flooding. Solutions that reduce reliance on fossil-fuel-powered vehicles and greenhouse gas emissions from the transportation sector, which account for approximately 30 percent of all U.S. emissions, take up the next top four in-demand solutions: walkability improvements, trails, bike infrastructure, and Complete Streets. Improved bicycle and pedestrian infrastructure also increase community resilience to climate impacts by providing additional layers of safe transportation.
The survey found that projects to increase the resilience of communities and reduce greenhouse gas emissions may also be leading to positive economic impacts. 47 percent of landscape architects and designers surveyed estimate their climate projects have a construction value of more than $1 million, with 29 percent saying the value of this work is more than $10 million.
Also, 45 percent of landscape architects and designers surveyed estimated their climate projects created more than 10 local planning, design, construction, management, or maintenance jobs in the past year. Climate solutions are resulting in well-paying creative and green jobs.
“The survey data shows that communities are greatly concerned about a range of climate risks and impacts. They are looking to landscape architects to provide nature-based solutions that both store carbon and increase resilience to extreme heat, flooding, drought, sea level rise, and other climate impacts,” said Torey Carter-Conneen, ASLA CEO. “There is also concern about biodiversity loss, particularly the loss of pollinators and the native habitat they rely on, and landscape architects are providing solutions that address the twinned climate and biodiversity crises.”
More key findings:
Designing resilience to climate impacts is at the forefront. 48 percent of landscape architects and designers surveyed stated that “all, a majority, or about half” of clients are now requesting plans and designs to increase resilience to existing or projected climate impacts, such as extreme heat, flooding, sea level rise, storm surges, and wildfires.
Specifically, some 43 percent of clients seek to increase resilience to climate shocks projected for the next 2-5 years, while 39 percent seek to address immediate climate risks or impacts.
38 percent of clients seek to increase resilience over the next 5-10 years, while 32 percent of clients are planning now for the long-term and seeking solutions for expected climate risks and impacts 10-50 years out.
Nature-based planning and design solutions are in demand. Public, non-profit, community, and private clients are looking to landscape architects to plan and design nature-based solutions to impacts such as wildfires, sea level rise, flooding, drought, extreme heat, and biodiversity loss and ecosystem degradation.
According to landscape architects, designers, and educators surveyed, these are the top solutions requested by clients for each climate impact area. Note: Not all climate impacts are relevant to the respondents’ regions.
Extreme heat solutions:
Street trees (64 percent)
Shade structures / canopies (60 percent)
Tree groves (35 percent)

Reducing greenhouse gas emissions is also now a key focus. Landscape architecture projects can incorporate Climate Positive Design practices so that they absorb more carbon than they emit over their lifespans. Projects at all scales can act as natural and designed carbon sinks, storing carbon in trees, shrubs, and carbon-sequestering materials, such as wood and pavers. 27 percent of respondents stated that “all, a majority, or about half” of clients are requesting projects that reduce or store greenhouse gas emissions now.
The top five strategies sought by clients to reduce emissions include:
Parks and open spaces, which include trees and grasses that sequester carbon.
Tree and shrub placement to reduce building energy use.
Habitat creation / restoration, which can increase the amount of trees and plants in a landscape, remove invasive species, and improve the overall health of natural systems, and the amount of carbon stored in landscapes.
Elimination of high-maintenance lawns, which involves reducing the corresponding use of fossil-fuel-based fertilizers and fossil-fuel-powered lawn movers and leaf blowers.
Minimizing soil disturbance, which helps keep intact carbon stored in soils.
Clients are also requesting materials that store carbon, such as woods and carbon-absorbing concrete.
Top five solutions:
Recycled materials, such as pavers that incorporate a high percentage of industrial byproducts.
Reused materials, such as wood or concrete, which eliminate the need to produce new materials.
Trees that absorb higher amounts of carbon than others, which include white oak, southern magnolia, London plane tree, and bald cypress trees.
Carbon-sequestering shrubs, groundcover, and grasses, such as native grasses with deeper roots than turfgrass.
Solar reflective materials that bounce back more sunlight and therefore reduce heat absorption and air conditioning energy use and expenses in adjacent buildings.
The United Nations Framework Convention on Climate Change (UNFCCC)’s 26th Conference of the Parties (COP26), which just began in Scotland and will continue over the next two weeks, is the crucial moment where global leaders must commit to achieving a 65 percent reduction in greenhouse gas emissions by the end of this decade. ASLA calls upon governments, particularly of nations with the largest historical emissions, to rapidly change course or risk breaching the 1.5C (2.7F) planetary warming limit established as part of the 2015 Paris climate agreement.
A recent report issued by the Intergovernmental Panel on Climate Change (IPCC) found that countries are already failing to live up to their commitments as outlined in the Paris agreement. With current nationally determined contributions (NDCs), global greenhouse gas emissions are on track to increase by 16 percent by 2030, compared to 2010 levels. And earlier this year, the International Energy Agency warned that greenhouse gas emissions in 2021 are expected to total 33 billion tonnes, an increase of 4.6 percent over 2020, and the second largest annual jump on record.
Over the course of the next two weeks, ASLA and its Climate Action Committee will be closely monitoring progress of the negotiations in Scotland. ASLA will be working in coordination with its climate action partners – The International Federation of Landscape Architects (IFLA), Climate Positive Design, Architecture 2030, We Are Still In, and The American Institute of Architects (AIA) — to share information in real time.
“We will be looking for more ambitious commitments – increased investments in nature-based approaches to sequestering greenhouse gas emissions and adapting to climate change and more equitable climate actions that undo climate injustices. We are hopeful COP26 will result in progress on our key goals as outlined through our commitments with IFLA and Architecture 2030,” said Torey Carter-Conneen, ASLA CEO.
ASLA also signed on to the Architecture 2030 1.5°C COP26 Communiqué, which calls for all governments to reduce greenhouse gas emissions by 65 percent by 2030 and achieve zero emissions by 2040. The call, the most ambitious climate challenge ever issued by the built environment professions, accelerates the current timeline to achieve emission reductions outlined in the Paris Climate Accord by a decade.
“By working closely with our built environment partners, we can amplify the voice of landscape architects in these critically important climate discussions,” said Tom Mroz, FASLA, ASLA President. “We must all do our part to get on a path to achieving a 65 percent reduction in emissions by 2030.”
Landscape architects plan and design with nature to help all communities reduce greenhouse gas emissions and adapt to a changing climate. Landscape architects use climate positive design approaches that transform parks and open spaces into natural carbon sinks. They develop resilient nature-based solutions that reduce the impacts of extreme heat; coastal, ground, and inland flooding; sea level rise; pollution; and wildfires. They also increase biodiversity and protect and restore ecosystems, which underpin life on Earth. Learn more at: https://climate.asla.org
Brooklyn Bridge Park, which pre-Covid boasted 5 million visitors a year, was the first major park to be created in Brooklyn since Frederick Law Olmsted and Calvert Vaux’s Prospect Park in the late 19th century. Five flat, concrete piers were re-imagined as sports fields, gardens, and playgrounds, all connected through interwoven green spaces and paths. A new berm reduced noise from the nearby Brooklyn Queens Expressway, an elevated highway that once produced a deafening “roar,” so much so that it was difficult to talk.
The first public meeting for the master plan of the park was way back in 1998. In just a few months, the final segment — Emily Warren Roebling Plaza — will open. A video with Michael Van Valkenburgh, FASLA, from 2009, as construction begins, offers a sense of his enduring passion for this transformative, two-decade-long project:
MVVA explains that the original “idea for the park came from Brooklynites, who live in the NYC borough with the least amount of park space.” Communities around the site couldn’t access the waterfront when it was a shipping terminal owned by the Port Authority of New York and New Jersey. More than a decade of advocacy by local community groups finally convinced elected leaders to stop the Port Authority’s plans to transform the defunct terminal into a profit-generating mixed-use development and instead created a city and state-financed public park.
Over the course of more than 400 public meetings while planning and designing the project, MVVA heard a few key messages: the park should “feel democratic,” and in order to accomplish that, should offer “many programs within its whole,” including desperately-needed space for recreation. The park should also feel friendly and accessible — “a space for everyday life, a place to relax.”
Brooklynites also wanted more than just views; they wanted to feel immersed in a restored natural environment along the East River – “to step into the water, smell the breeze, and feel surrounded by the landscape.” To bring those benefits to multiple surrounding neighborhoods, MVVA created a plan that “stretched both ends of the park” beyond its originally conceived boundaries.
The park itself is a model of urban reuse. Instead of tearing down the pier infrastructure, MVVA found ways to reuse both the stronger and weaker parts of it, arranging park uses on the surface based on the piers’ structural capacity. Some piers had piles that would only support limited weight so any programs on the surface had to be “light and relatively thin.” Pier 1 had the strongest supports, so it became possible to build up new land forms.
Within the park itself, yellow pine wood from a demolished factory was reused as site furniture; piles and pier structures became playground and park elements; granite was broken up and became rip rap; and bulk fill from a subway tunnel extraction was used to build up land. A shed found on Pier 2 shed was also reimagined as a shade structure for basketball courts, and a pile field at Pier 1 was kept to protect a new salt marsh.
MVVA carved out land forms within the site, creating sweeping lawns and gardens down to the waterfront that also act as a resilient flood basin during storm surges. More than 3,000 trees were planted along with a rich understory of native plants, all guided by an ecological approach. As in nature, the trees and plants compete for resources and adapt over time, instead of being isolated specimens like in a typical urban park. Plants were also selected to “support human comfort, wind shelter, and shade.”
“If you ask a hundred different people why they come to Brooklyn Bridge Park, you could easily get a hundred different answers. Sports are interspersed with epic views, social spaces, natural beauty, and quiet moments,” Van Valkenburgh explains.
The Rose Barba prize jury also honored another innovative space: Parques del Río Medellín in Medellín, Colombia, designed by Sebastian Monsalve Gomez and Juan David Hoyos Taborda. The park, also decades in the making, creates new access to the Medellín River and partly de-channelizes the river and restores its ecosystem.
The Rosa Barba International Landscape Prize included an award of €15,000 ($17,439). The prize jury included Esteban Leon, UN-Habitat; Cristina Castelbranco, a landscape architect and professor at the University of Lisbon; Kongjian Yu, FASLA, a leading Chinese landscape architect and founder of Turenscape; James Hayter, a landscape architect and president of the International Federation of Landscape Architects (IFLA); and Julie Bargmann, a landscape architect, professor at the University of Virginia, and winner of the first Cornelia Hahn Oberlander International Landscape Architecture Prize.
Landscape Architects Unite in Advance of Key United Nations Climate Change Conference
ASLA announced it will join a global coalition of 70,000 landscape architects in 77 countries in committing to limiting planetary warming to 1.5°C (2.7 °F). This is the largest coalition of landscape architecture professionals ever assembled to advance climate action.
IFLA’s Climate Action Commitment will be issued to sovereign nations at the United Nations Framework Convention on Climate Change (UNFCCC)’s 26th Conference of the Parties (COP26), which will be held in Scotland, October 31 – November 12.
ASLA has committed to the six goals outlined in the IFLA Climate Action Commitment:
1) Advancing the United Nations Sustainable Development Goals (UN SDGs)
ASLA and its member landscape architects and designers will accelerate efforts to protect and repair ecosystems.
2) Attaining Global Net Zero Emissions by 2040
ASLA and its members will dramatically reduce operational and embodied carbon emissions produced by projects, increasingly harness the unique capacity of landscapes to draw down carbon dioxide, and continue to advocate for low-carbon multi-modal transport systems.
3) Enhancing Capacity and Resilience of Livable Cities and Communities
Implementing green infrastructure approaches, ASLA and its members will increase efforts to mitigate the urban heat island effect and reduce climate impacts associated with fire, drought, and flooding.
4) Advocating for Climate Justice and Social Well-Being
ASLA and its members will maintain our priority on equity and equality and ensure the right to nearby green spaces and clean water and air.
5) Learning from Cultural Knowledge Systems
ASLA and its members commit to respecting and working with indigenous communities and honoring cultural land management practices to mitigate climate change impacts and continue work towards reconciliation.
6) Galvanizing Climate Leadership
Landscape architects are uniquely positioned to lead the built environment community’s response to the climate crisis. ASLA will continue to collaborate with clients, suppliers, and allied professions to champion climate positive landscapes, which involves planning and designing landscapes that sequester more greenhouse gas emissions than they emit.
“ASLA is proud to be joining forces with IFLA and the global community of landscape architects in advancing our climate action goals,” said Torey Carter-Conneen, CEO, ASLA. “We speak as one voice, globally, when it comes to advancing climate action.”
“As landscape architects we can make a tremendous difference to climate change and to climate action through our work, so thinking globally but acting locally is critical,” said IFLA President James Hayter.
“In a year marked by historic flooding in Europe and China and deadly wildfires and heat waves in the United States, it’s clear we’re running out of time to start healing a century’s worth of harm done to our Earth and its atmosphere,” said Tom Mroz, FASLA, ASLA President.
“I am gratified that Climate Positive Design has been incorporated into the global Commitment,” said Pamela Conrad, ASLA, Founder of Climate Positive Design, Principal at CMG Landscape Architecture in San Francisco, and IFLA Climate Change Working Group Vice Chair. “All landscape architects must rapidly scale up their work transforming designed landscapes into natural carbon sinks.”
The IFLA Climate Action Commitment is the second major coalition ASLA has joined this year. ASLA also signed on to Architecture 2030’s 1.5°C COP26 Communiqué, calling for built environment industries to achieve zero greenhouse gas emissions by 2040.
