Asian Infrastructure Investment Bank Pavilion, Blue Zone

“Nature plays a critical role in providing valuable resources and services that underpin and support sustainable development and the well-being of people and the planet. Well-functioning and diverse ecosystems regulate the Earth’s climate, build resilience to the impacts of climate change, and enhance the sustainable management of water and land. Forests, wetlands, coral reefs can effectively provide infrastructure functions while delivering additional climate and biodiversity co-benefits.

To achieve the goals and targets of the Kunming – Montreal Global Biodiversity Framework, both increasing nature-positive financial flows and reducing nature-negative flows will be needed. International financial institutions play a key role in closing the $700 billion annual global biodiversity finance gap and helping countries meet their commitments.”

This high-level side event will “bring together representatives from international financial institutions, governments, the private sector, think tanks, and academia to discuss the opportunities and challenges associated with scaling up nature-positive and biodiversity financing.”

Speaker:

  • Kongjian Yu, FASLA

Delegates will highlight the key role of landscape architecture in maximizing the benefits of nature for people and communities

ASLA is sending two delegates to COP28 in Dubai, UAE, and eight virtual delegates will join online. This is the second year ASLA has been an NGO observer to the UN Framework Convention on Climate Change (UNFCCC) Conference of Parties (COP) process.

At COP28, ASLA delegates will argue:

Nature-based solutions to climate change and biodiversity loss are more than mangroves, forests, and grasslands. Using landscape architecture strategies, they can be woven into places where people live. They can take the form of parks, recreation areas, streets, coastal infrastructure, and more. Through inclusive design, they can provide even greater benefits to people and support the healthy urban ecosystems people rely on.

While more communities are integrating nature-based solutions, those advances are not widespread. All communities need equitable access to best practices, project financing, and the landscape architecture, planning, ecology, and engineering professionals who make these projects a reality.

Landscape architects design nature-based solutions to create real benefits for people and communities:

1) Increased Biodiversity
Nature-positive landscapes are the foundation of terrestrial ecosystems and efforts to achieve 30 x 2030 and 10% net biodiversity goals, restore global ecosystems, and increase and protect biodiversity.

2) Improved Human Health and Livability 
Accessible public landscapes, such as parks and recreation areas, provide proven physical and mental health benefits that reduce healthcare costs and increase community cohesion.

3) Going Beyond Net-Zero
Landscapes are the most efficient way to store carbon and achieve zero embodied and operational emissions and double carbon sequestration by 2040.

4) Strengthened Resilience 
Healthy, biodiverse landscapes that store carbon in trees, plants, and soils also increase people’s resilience to climate impacts, such as extreme heat, flooding, drought, and sea level rise.

5) Expanded Investment and Sustainable Livelihoods
When woven into communities, nature-based solutions become resilient assets that lead to increased investment in housing, infrastructure, and public amenities, and create sustainable local livelihoods.

In-person delegates include:

At COP28, Countries Need to Get on Track to Hit 2030 Goals

Jared GreenLeave a comment

In 2023, temperatures were the hottest on record. This is because the current level of heat-trapping greenhouse gases in the atmosphere hasn’t been seen in 3-5 million years. A slew of United Nations (UN) climate reports released over the past few months tell the same story: the world’s governments are taking action to reduce global temperatures but are not moving fast enough. The lack of progress is only increasing climate risks.

The latest Emissions Gap Report from the UN Environment Program (UNEP) finds that current pledges by countries that signed on to the Paris Agreement will lead to a 2.5°C (4.5°F) to 2.9°C (5.2°F°) temperature rise this century, far surpassing the goal of a 1.5°C (2.7°F) temperature increase. And last year, global greenhouse gas emissions increased by 1.2 per cent to reach a new high of 57.4 billion tonnes of carbon dioxide (GtCO2e). This means governments, particularly the largest historical polluters, need to dramatically scale up their emission reduction efforts.

World leaders are looking to the upcoming global climate summit — COP28 — in Dubai, United Arab Emirates, to build new momentum. There, countries will confirm the “global stocktake,” which analyzes emissions data from the past five years, and set new targets in 2025 to be achieved by 2035.

“Every fraction of a degree matters, but we are severely off track. COP28 is our time to change that,” said Simon Stiell, Executive Secretary of UN Climate Change. “It’s time to show the massive benefits now of bolder climate action: more jobs, higher wages, economic growth, opportunity and stability, less pollution and better health.”

The UN’s Intergovernmental Panel on Climate Change found that countries need to cut global greenhouse gases 43 percent by 2030 in comparison with 2019 levels to keep goals in reach.

Unfortunately, countries are only taking “baby steps” in this direction, Stiell has said. The UN analyzed the nationally determined commitments (NDCs) of 195 countries that signed on to the Paris Agreement. They found that if current commitments are met, global greenhouse gas emissions will increase by 2 percent by 2030 in comparison with 2019 levels, which is very far from the 43 percent drop needed.

To speed up the peaking process and start making more dramatic cuts, countries need to invest more in transforming their economies and communities, particularly the transition to renewable energy. The International Energy Agency (IEA) says $4.5 trillion of investment in renewable energy is needed each year by 2030 to keep the 1.5°C temperature increase goal in reach. In 2023, renewable energy spending is anticipated to be $1.8 trillion, less than half what is required.

Greater investment in renewable energy also means more planning and design work will be needed to appropriately site the expansion of wind and solar power across landscapes. As Hood Design Studio demonstrated with the Solar Strand at the University at Buffalo, it can be done in a way that reduces impacts on wildlife and supports ecological restoration.

The risks of slow progress on reducing emissions are only becoming clearer. A report published in The Lancet by 114 scientists contends that “climate change continues to have a worsening effect on health and mortality around the world.” The New York Times reports: “One of the starkest findings is that heat-related deaths of people older than 65 have increased by 85 percent since the 1990s.”

The U.S. government also recently released its fifth national climate assessment. It states: “Across the country, efforts to adapt to climate change and reduce emissions have expanded since 2018, and U.S. emissions have fallen since peaking in 2007. However, without deeper cuts in global net greenhouse gas emissions and accelerated adaptation efforts, severe climate risks to the United States will continue to grow.”

The assessment finds that states, tribal authorities, and cities are taking advantage of new adaptation measures, including “nature-based solutions, such as restoring coastal wetlands and oyster reefs.” It also points to the growth of green infrastructure to tackle increased stormwater; efforts to manage vegetation to reduce wildfire risks; and the rise of urban heat plans, which leverage expanded tree canopies to reduce dangerous heat islands.

But they still conclude that even in a wealthy country like the U.S., “current adaptation efforts and investments are insufficient to reduce today’s climate-related risks and keep pace with future changes in the climate.”

Extreme weather events — longer heatwaves and droughts, worse floods and wildfires — have grown in number. In the 1980s, the U.S. experienced approximately 3 billion-dollar disasters per year. But over the past four years, that has skyrocketed to more than 22 billion-dollar events annually, and many of these events are highly costly. “Extreme events cost the U.S. close to $150 billion each year—a conservative estimate that does not account for loss of life, healthcare-related costs, or damages to ecosystem services.”

In this new era of increased climate impacts, landscape architects, planners, engineers, and architects are needed more than ever to envision new climate-resilient infrastructure that keep communities safe, and also pragmatic climate migration plans where this isn’t feasible.

Climate policymakers also see the need for new global goals for adaptation, an area where landscape architects can provide leadership and effective strategies.

For example, in China, 70 cities have joined the “Sponge City” movement led by landscape architect Kongjian Yu, FASLA, founder of Turenscape and the 2023 Cornelia Hahn Oberlander International Landscape Architecture Prize winner. The goal is that by 2030, 80 percent of these cities will absorb 70 percent of rainfall through green infrastructure approaches, reducing the impacts of sea level rise and flooding.

A range of adaptation targets, rooted in nature-based solutions, are needed to not only reduce damages from flooding and sea level rise, but also extreme heat, drought, and other climate health impacts.

Nature-based solutions are smart because they provide many additional benefits — increased biodiversity, greater carbon drawdown, improved health, and economic growth. At COP28, landscape architect delegates will press global leaders to increase investment in these solutions.

Close watchers of the climate negotiations expect to see progress at COP28 on developing new adaptation goals. These targets can help drive the creation of more accurate climate financing goals, and spur wealthy countries to donate more loss and damage funds to the people and communities already experiencing impacts.

Socially Just Public Spaces Are Crucial to Flourishing Societies

The Dirt ContributorLeave a comment
Why Public Space Matters / Oxford University Press

By Grace Mitchell Tada

One of the most radical instances of public space transformation happened recently. During the early months of the Covid-19 pandemic, public space transformed into “a medical resource, a distribution hub, an overflow space, a center of protest and resistance, a gym, a senior center, a community center, a daycare center, a schoolyard, a night club, a transportation corridor, an outdoor restaurant, a shopping mall, a children’s playground, an outdoor theater, a music venue, a nature center, and a place of belonging and ‘being at home.’”

As Setha Low writes in her book Why Public Space Matters, “public space mattered.”

Why do public spaces matter? For Low, an anthropologist by training and distinguished professor of environmental psychology, geography, anthropology, and women’s studies at the City University of New York, their importance lies in their social value and their role in establishing socially just communities.

They are places of social interaction and community building. They are places where people learn to live with difference. They offer a stage for political and social protest and can encourage democracy and equality. They are crucial to the flourishing of people and their greater societies.

Public space encompasses all sorts of spaces: the typical parks, plazas, and libraries, but also streets and sidewalks, social infrastructure, and “environmental linkages.” Yet the definition of public space varies according to who is defining it. A landscape architect, for instance, centers spatial form and people’s interactions with the environment, while a social scientist focuses on social relations.

To establish a more uniform understanding of public space, Low proposes six characteristics that people across disciplines can use to define any public space:

  • Physical aspects
  • Ownership
  • Governance or management authority and funding
  • Control and influence, rules and regulations, and access
  • Symbolic/historical meaning
  • And political activity

Determining these six characteristics shows that “there are many kinds, not one ideal type” of public space.

Throughout the book, Low draws on her decades of public space research, which began in 1978. Since that time, issues including racial injustice, socioeconomic inequality, and climate change, among others, have always been important, but are even more acutely so now. It’s on these issues that she focuses her book.

Low points to Jones Beach, 20 miles from New York City and one of the most popular state parks in New York, as a public space where park visitors experience social justice. Her two years of research showed how many diverse groups of people frequent a space where they feel they are accepted and belong, especially in a context where surrounding towns restrict beach access.

The site’s design accommodates and welcomes different people through physical design and markers—smooth boardwalks and ramps, ample benches, signs that speak to the historic Lakota Village, and so forth. But, furthermore, Jones Beach, has so “many kinds of people, environments to experience, and things to do that most people find a place for themselves and thus feel represented and welcome.” They also feel recognized and respected.

Low argues that places like Jones Beach are key to a democratic society and public space—and, as a result, so is evaluating social justice in public spaces. She offers the Social Justice and Public Space Evaluation Framework to both examine and design just spaces, which is useful to designers and community members alike.

Parks sites like Jones Beach, as well as other sites Low studies, such as Walkway Over the Hudson Historical Park in Poughkeepsie and Highland, New York, and Lake Welch Beach at Harriman State Park, New York, embody stereotypical public spaces, especially in the minds of landscape architects.

Another type of public space she examines is less often considered: the streets, sidewalks, plazas, bridges, and other public spaces used as part of the informal economy. This economy can be as much of 70 percent of the workforce in urban sub-Saharan Africa and Southeast Asia. Working in these public spaces — including in neoliberal societies like our own that have few safeguards for poorer and unhoused people — makes workers especially exposed to physical violence, theft, police surveillance, and incarceration.

Selling, delivering, waste collecting, care-giving: all these activities unfold in public spaces. In the landscape profession where glamorous park designs often grab the most attention, it’s important to remember that “for much of the world, public space is a place of work or looking for work and building social capital to find a better or more stable job.” Low’s ethnographic case studies from around the world demonstrate how these spaces are adaptable and empowering to the people who use them as their workplaces.

As a medical anthropologist by training, Low consistently makes clear that social dynamics are at the heart of her understanding of public space. Yet she sees environmental sustainability as an integral thread of that understanding. Her first teaching job, in the department of landscape architecture and regional planning at the University of Pennsylvania, was to instruct “human and environmental health as an outcome of ecological planning.”

For Low, elements like community gardens and urban agriculture are ecological boons not in themselves, but because they “[build] stronger communities, [support] social reproduction, and [promote] environmental justice.” She highlights the words of a Detroit resident: “Environmental justice is not just about the distribution of bad stuff….It’s also about the distribution of power among communities that have historically only been subjects and experiments of power structures.”

The book’s various chapters showcase Low’s systematic ethnographies that undergird her findings. She observes, talks, maps, and writes field notes which ultimately reveal patterns of behaviors and interests. Low appreciates this methodology of ethnography because, rather than, say, counting the number of people in a space, “it focuses on why people are doing what they are doing from their own point of view.”

Ethnography also means that the perspective of the researcher—by nature subjective—plays a significant role in the research. To illustrate her reflexivity, the book is scattered with excerpts from Low’s field notes about children creating play spaces in Nairobi, improvised workplaces on the streets of Varanasi, her ecological planning work on Sanibel Island, Florida.

It’s these sharp, empathetic observations of public spaces—what makes them work, the people that activate them, and the diversity of ways in which they use these spaces—that animate the book and so vividly illustrate her assertion that public spaces are crucial to flourishing societies.

Low writes of her decades of research in a way that makes her work seem effortless. Her evocative field notes reveal the pleasure she takes in experiencing and doing her work understanding urban landscapes. Yet it’s also clear that she dedicated much effort and time to each of her case studies. She acknowledges that certain projects took years as she observed participants and conducted extensive interviews.

She knows this is an impractical span of time for landscape architects wishing to conduct similar research or evaluation. But they nonetheless require a rigorous way to study interactions between humans and their environment. So the book’s final chapter offers toolkits, methodologies, and resources for designing and evaluating public spaces. Most notably, Low provides a blueprint for how readers can achieve less time-intensive public space ethnographies in the same vein as her own.

Low calls this method the Toolkit for the Ethnographic Study of Space (TESS), which she developed in conjunction with her colleagues. She co-opted some techniques from the Rapid Ethnographic Assessment Procedure, a methodology used by medical anthropologists that takes only months, as well as other behavioral techniques.

Ultimately, TESS consists of five steps:

1) Mapping
2) Participant observation
3) Interviewing
4) Historical documentation
5) Analysis

“It is not a design toolkit,” she writes, “but an ethnographic one developed to enable you to become your own social scientist and get directly involved in public space activism to improve cities for the future.”

Low believes in the power of socially just public space to have transformative effects. While a park or sidewalk or plaza may not resolve issues of social injustice alone, she believes they can be places to start. She has presented the framework, and her own examples, to empower the reader to begin transformation of their own effort, in their own community.

How Fire-Prone Communities Can Reduce Their Risk

Jared GreenLeave a comment
Fire risk reduction strategy / SWA

16% of Americans now live in “designated fire hazard areas,” states SWA, a landscape architecture firm. And nearly 80 million U.S. properties face a “significant chance of exposure” to wildfires. Risks to both people and property are expected to dramatically increase by 2050.

To address this threat, SWA created an illustrated guide — Playbook for the Pyrocene, which offers 20 community planning and design strategies that can be applied by landscape architects, planners, homeowners, and developers.

The guide is authored by Jonah Susskind, senior research associate at SWA’s XL Research and Innovation Lab, and a team of researchers at the firm: Alison Ecker, Sydnie Zhang, Harrison Raine, Shannon Clancy, Dallas Ford, Peter Rustad, Rajpankaja Talukdar, and Ted Vuchinich.

“As wildfires become more frequent and destructive, we must rethink how communities are planned and designed. Fire is as complex as it is elemental, and there will never be a singular, tidy solution,” writes Alison Ecker, SWA, in the guide.

Instead SWA offers communities a way to layer solutions and apply practical, science-based guidelines and strategies to reduce risk at the community scale.

Fire risk reduction strategy / SWA

The guide synthesizes research findings from fire science, forestry, land use planning, and emergency management. And it builds on many years of wildfire work by SWA. “First, a set of landscape strategies developed with the community of Paradise, California after the 2018 Camp Fire. Then, a 945-acre planning study in Sonoma County, California. And, ultimately, a collaboration with the California Governor’s Office to develop statewide guidelines for wildfire planning,” Jackson Rollings, director of communications at SWA, explained.

“After the tragedy in Lahaina in Maui, there’s been a lot of reporting on rebuilding and recovery, but not nearly enough on actionable solutions and community-scale planning. This resource is intended to fill that knowledge gap and make these strategies plain and legible,” he added.

SWA argues that “supercharged fires” are growing worldwide. They are caused by “misguided” fire suppression policies; climate change; and unabated development in the wildland-urban interface (WUI).

According to the U.S. Fire Administration, WUI is a term for fire-prone lands where “human development meets or intermingles with undeveloped wildland or vegetative fuels.” With increased sprawl, the WUI is growing by 2 million acres each year.

Susskind delves into each cause of increased wildfire risk:

“Fire suppression policies resulted in far fewer acres burned, but over time, they inadvertently created an immense stockpile of unburnt fuels. As a result, today’s fires have become much larger and tend to burn much hotter than they would have naturally.”

“Eminent fire historian Stephen Pyne has dubbed our current epoch the Pyrocene because of the degree to which human manipulation of natural fire regimes have permanently altered Earth systems.”

Climate change is also fueling more destructive annual megafires. “Prolonged periods of record-breaking heat and drought have impacted fire-prone ecosystems by desiccating forests and grasslands and significantly increasing the length of annual fire seasons.”

And living in the WUI puts many people in the most immediate danger. “In recent decades, due to the housing-affordability crisis, NIMBYism, and local zoning restrictions, more affordable development has been pushed further away from city centers to comply with state mandates, and the WUI has become the fastest growing land use category in the US. Today, nearly 100 million people (about a third of the U.S. population) live in the WUI.”

Fire risk reduction strategy / SWA

In California, “more than 80 percent of California’s fire-related structure loss has occurred in these high-risk zones.” And if WUI development continues at a similar pace over the next thirty years, 20 million Californians could call these fire-prone landscapes home.

(California currently accounts for approximately half of properties at risk from wildfire. Other states with major fire hazards are Texas, Colorado, Arizona, Idaho, Washington, Oklahoma, Oregon, Montana, Utah, and many others.)

“We did not intend for the resource to influence high-level land-use planning decisions, which are usually much further upstream,” Susskind told us.

“The questions we are trying to answer here are not so much where to build, but rather how to build better within the context of wildfire broadly.”

Fire risk reduction strategy / SWA

A key part of that is learning how to design with ecosystems that are naturally dependent on fire.

“This means [designing] in ways that support fire as a critical part of ecosystem health and stability. Each of the strategies can be applied in order to reduce risks for frontline communities while simultaneously ensuring that fire can effectively support fire-dependent ecologies,” Susskind said.

Fire risk reduction strategy / SWA

SWA also sees the guide as just the start of a broader, collaborative effort to reduce risks.

“Landscape architects, urban designers, planners, and developers all have work to do to fill critical knowledge gaps. Best practices will need to be expanded and codified through professional licensure and institutional accreditation. Practitioners will need to have a firm grasp of the basic principles of fire behavior, vegetation management, and defensible space.”

“We will need to build and maintain partnerships with firefighting agencies, fire-safe councils, prescribed burn associations, and other key organizations. We will also need to advocate for more robust and ecologically informed wildfire policies that boost accountability for those making development decisions in high-risk areas.”

The Very Personal Impact of Community Green Spaces

By Alden E. Stoner

While landscape architects’ work touches people’s lives every day, they rarely get to hear from the people who interact with their work. Designing outdoor spaces and using those spaces are two distinct phases. But what if there were a way to get a glimpse into how people feel about landscaped green spaces, years or even decades after they were designed?

At Nature Sacred, we believe nature offers powerful benefits for health and mental well-being, particularly in urban areas, where it can be hard to connect to the natural world. We’ve spent the past 25 years supporting green spaces that are nearby and integrated into the communities that use them, open to all, and designed to encourage contemplation and peace. We call them Sacred Places.

When we built our first Sacred Place, we tucked a waterproof journal under the wooden bench that serves as a centerpiece of the space. We were surprised and moved by the volume and breadth of writings that visitors added to it. Nature emboldened people to share their ideas, loves, losses, gratitude, and encouragement with great vulnerability – and sometimes a bit of humor.

As we developed more Sacred Places – now over 100 across the U.S. – we added a journal to each one. Our archive of journals grew, and we realized the wisdom contained in them was too valuable to keep to ourselves. We collected the most touching, memorable, and thought-provoking entries in a book that was published last year titled BenchTalk: Wisdoms Inspired in Nature.

BenchTalk is not only a testament to the power of nature but also to the work of the landscape architects who bring each Sacred Place to life with the help of a community-led design process. Throughout the book, a constant theme is people’s gratitude for a small pocket of nature where they can reflect.

“Never knew of this space – little sanctuary amid the rubble of the BQE. Boy do we need more spaces like it – to allow ourselves a moment to connect with the infinite, with the silent rhythms within – even as the traffic hums unabated, and planes fly overhead.” – Naval Cemetery Landscape in Brooklyn, New York

We worked with Nelson Byrd Woltz Landscape Architects and Marvel Designs to transform a 1.5-acre former cemetery into an award-winning green space that’s filled with life while honoring the site’s history and the community’s needs. A partnership with Brooklyn Community Housing and Services offers formerly homeless residents a chance to interact with nature in their community. And a local high school has developed a science curriculum based on the Sacred Place’s meadow, sparking an appreciation for nature among a new generation.

“Looking up at these towering trees, I am overcome with the feeling of being blessed. I am also keenly aware that these arching trunks and branches are only half the picture. I thus ask these deep roots to give me strength. Thank you for this space.” – The Green Road at Walter Reed Medical Center in Bethesda, Maryland

The Green Road was designed with the help of Jack Sullivan, FASLA, to provide a place for veterans to heal from PTSD and traumatic brain injuries. Featuring a forested area with paved, accessible trails, the space intentionally retained “wild” and natural elements to mirror the wild and chaotic realities of war that these veterans have lived through.

The Terrace Garden is a therapeutic garden filled with plants to mark the changing seasons, connected to the Family Birth Center and Cardiovascular ICU at Legacy Emanuel Medical Center. Designed in collaboration with Brian Bainnson, ASLA, of Quatrefoil, the space bears witness to the highs and lows of life, offering serenity for laboring mothers and recovering cardiac patients, as well as the doctors and nurses who work tirelessly to help them.

The Butterfly Garden and Overlook is part of our Landscapes of Resilience Project, which aims to show how green spaces can support community resilience and recovery in the wake of a tragedy – in this case, the tornado that killed 161 Joplin residents in 2011. We collaborated with Traci Sooter and students from Drury University, city officials, psychologists, and community members to design this healing garden. The result is a Sacred Place with design themes related to the mourning process and a butterfly pavilion referencing children’s reflections that butterflies helped them during the storm.

In every corner of the country, in neighborhoods, universities, hospitals, prisons, and more, we’ve seen that creating restful green spaces with community input has a profound impact on people’s lives. If you’d like to join us in this work, please reach out.

The Cultural Landscape Foundation (TCLF) announced Chinese landscape architect Kongjian Yu, FASLA, has won the 2023 Cornelia Hahn Oberlander International Landscape Architecture Prize for his influential planning, design, and advocacy work to advance “sponge cities.”

The biennial award of $100,000 will include two years of public engagement focused on Yu’s work, ideas, and the state of contemporary landscape architecture.

The prize is named after German-born Canadian landscape architect Cornelia Hahn Oberlander, FASLA, who passed away in 2021 at age 99.

TCLF states that the prize is bestowed on a recipient who is “exceptionally talented, creative, courageous, and visionary” and has “a significant body of built work that exemplifies the art of landscape architecture.”

The seven-person international prize jury, chaired by Elizabeth Mossop, FASLA, wrote: “A brilliant and prolific designer, Kongjian Yu is also a force for progressive change in landscape architecture around the world. Through built works, lectures, publications, teaching, and a series of celebrated letter to the leaders of China, he has striven to direct landscape practices away from a destructive confrontation with natural forces toward a more optimistic position of cooperation and adaptation.”

Yu said: “I deeply appreciate the jury for their brave decision to recognize my work, when there were so many talented nominees who I believe much deserve this prize. They include our fields’ well-established giants in developed countries, who have inspired my work.”

“I deeply believe that landscape architecture can and will play a key role in healing the planet. As Cornelia Oberlander stated: ‘Landscape architects must be leaders, especially in dealing with the effects of climate change.’”

Yu’s “sponge cities” concept is about using nature-based solutions to reduce widespread urban flooding brought on by development and climate change. These solutions act as “sponges soaking up rainfall” instead of containing and conveying water through traditional concrete infrastructure.

Sponges can be layered and take a variety of forms: “constructed wetlands, greenways, parks, canopy tree and woodland protection, rain gardens, green roofs, permeable pavements, bioswales, and other measures.”

Thanks to Yu’s multi-decade advocacy campaign, China made investment in sponge cities its national policy in 2013.

Since then, more than 70 Chinese cities have implemented sponge policies and programs. The goal is that by 2030, 80% of the cities will absorb 70% of rainfall. This effort forms one of the planet’s most ambitious Mega Eco-Projects.

Charles Birnbaum, FASLA, President and CEO of TCLF, said Yu’s ideas are “inspiring planners and decision makers in Australia, Bangladesh, Canada, Denmark, Egypt, England, India, Indonesia, Kenya, Mexico, The Netherlands, New Zealand, Russia, Singapore, South Africa, Sweden, and elsewhere.”

Yu is the founder and leader of the Graduate School of Landscape Architecture and the College of Architecture and Landscape Architecture at Peking University in Bejing. He is also founder and principal designer of Turenscape, a landscape architecture firm with more than 400 employees.

According to TCLF, Yu and his firm have built 600 projects in more than 200 cities; mostly in China, but also in France, Indonesia, Russia, Singapore, Thailand, and the U.S.

A few of Yu’s key projects:

“One of the first ‘sponge cities’ projects to gain wide attention, this 80-acre (34.2-hectare) national urban wetland park was created from a dying wetland.” Yu built ponds and mounds, with native grasses, meadows, and silver birch trees accessible via pathways and elevated walkways.

“One of the earliest and the most significant demonstration and multi-functional projects of the nationwide sponge city effort.” 168 acres (68 hectares) of polluted wetlands were restored and became a park that also integrates ponds, rice paddies, greenways, and coastal habitat into a “holistic sponge system.”

And in the U.S., Yu designed:

At two-thirds of an acre (.27-hectare), this small park in the Chinatown-International District Neighborhood features a bold red “metal gateway inspired by Asian paper cutting and folding traditions.” Yu partnered with the Seattle-based firm MIG | SvR to design a park with “multiple garden terraces, inspired by the rice paddies of Yu’s agrarian upbringing, and numerous gathering and performance spaces,” TCLF writes.

In the book Designed Ecologies: The Landscape Architecture of Kongjian Yu, (2012), William Saunders writes: “During the 1966 to 1976 Cultural Revolution … [Yu] grew up near an enchanting forest and a fish-filled creek, only to see the forest cut down and the creek become too polluted to support life. This helps explain the depth of his commitment to recreating and protecting natural abundance.”

“He suffered social ostracism in the countryside for having wealthy ancestors and then for being a ‘country bumpkin’ when he made it to the big city. This helps us understand his conviction that parks are to be enjoyed by all ranks of people.”

“He loved farming and was proud that his commune used every square meter of its land productively. This helps explain his revulsion to landscapes that are ‘merely’ ornamental.”

“He learned how to deploy scarce water resources and cultivate crops in ways that ensured their survival. And this helps us understand his will to create parks that are low-maintenance and ‘productive.’”

ASLA and the ASLA Fund have released a comprehensive, freely-available guide: Towards Zero Emission Business Operations: A Landscape Architect’s Guide to Reducing the Climate Impacts of Offices.

The guide is designed to help landscape architecture firms of all sizes navigate the transition to zero emission offices more easily.

It outlines more than 110 strategies landscape architecture firms can implement to reduce their business and project greenhouse gas (GHG) emissions by 50-65% by 2030 and achieve zero emissions by 2040.

The guide provides best practice strategies relevant for firms that rent or own their offices. It offers firms ways to:

  • Measure their carbon footprint
  • Develop a climate action plan to reduce emissions
  • Take actions to reduce Scope 1, 2, and 3 emissions

The ASLA Climate Action Committee produced Towards Zero Emission Business Operations to support landscape architecture firms in achieving the goals of the ASLA Climate Action Plan.

The guide is authored by landscape architect Ronnie Siegel, ASLA, founder, Swire Siegel, Landscape Architects and ASLA Climate Action Committee Member, who interviewed 19 landscape architecture, architecture, and sustainability consulting companies to develop the resource.

“Towards Zero Emission Business Operations is a must-read for any landscape architecture firm serious about decarbonizing their business. These smart strategies can help firms not only reduce their emissions but also save money and increase the health and well-being of their employees,” said ASLA CEO Torey Carter-Conneen.

“Decarbonization, electrification, and the transition to renewable energy create new opportunities for landscape architecture firms. By measuring emissions, making a plan, and taking action, any firm can get on a path to zero emissions,” said Ronnie Siegel, ASLA.

The guide builds on the ASLA Climate Action Plan and the Climate Action Field Guide for ASLA Members, which chart a pathway for landscape architects to achieve zero greenhouse gas emissions in their projects and operations and increase carbon sequestration by 2040.

In 2022, the Climate Action Plan was developed by a high-profile Task Force of five landscape architects chaired by Pamela Conrad, ASLA, founder of Climate Positive Design, and a 17-member Advisory Group. It outlines a bold vision for 2040 and 71 actions to be taken by 2025.

Our Vision for 2040:

All landscape architecture projects will simultaneously:

  • Achieve zero embodied and operational emissions and increase carbon sequestration
  • Provide significant economic benefits in the form of measurable ecosystem services, health co-benefits, sequestration, and green jobs
  • Address climate injustices, empower communities, and increase equitable distribution of climate investments
  • Restore ecosystems and increase and protect biodiversity

To make progress on the Climate Action Plan, ASLA and the ASLA Fund also recently released Collaborating with Industry Partners on Climate Action and Biodiversity: A Guide to Conversations Among Landscape Architects, Vendors, and Product Manufacturers.

The ASLA Climate Action Committee and Corporate Member Committee curated more than 70 questions landscape architects can ask vendors and product manufacturers to advance climate and biodiversity goals.

Landscape Architects Are Key to Increasing Carbon Drawdown

“To quote Vaclav Smil: ‘human societies are nothing but subsystems of the lithosphere, the Earth’s thin veneer of life, which is ultimately run by bacteria, fungi and green plants,'” said José M. Almiñana, FASLA, Principal, Andropogon Associates, and ASLA Climate Action Plan Task Force Member at Greenbuild in Washington, D.C.

Within this system, there is a “sticky substance that holds soils together.” It is called glomalin, and it’s a protein produced by mycorrhizal fungi. “It’s responsible for sequestering 27% of the carbon in soils,” Almiñana explained.

Humanity will decide what happens to the future of this thin veneer. If we preserve and regenerate landscapes, we will ensure they store more carbon. If we use a “place-based approach,” we will also help communities better connect to restoration efforts.

For example, the Central Park Development Plan* in Denver, Colorado reimagined a former airport landscape that was “polluted and decimated.” A new open space plan proposed by Andropogon in the mid 1990s enabled the restoration of a buried creek and the landscape (see image above).

“Once the decision was made to protect open space and recover the creek, all sorts of productive opportunities became a possibility.”

Almiñana’s point was that carbon sequestration must start with the landscape. And improving the health of landscapes will not only yield more carbon storage, but also provide more climate resilience and other important human health benefits.

Much of the conversation about climate change and the built environment has been focused on “how to do less bad” by reducing carbon-intensive materials, said Katie Riddle, ASLA, Director of Professional Practice at ASLA.

This is important work, but among the design professions, only “landscape architects can also do more good” by increasing carbon drawdown in the landscape.

Riddle highlighted a 2017 study from The Nature Conservancy, which found that “increasing carbon sequestration in plant biomass has the greatest potential to reduce net carbon emissions and slow the effects of climate change.”

These kinds of ecological strategies form the foundation of the ASLA Climate Action Plan, Riddle said.

Chris Hardy, ASLA, Senior Associate, Sasaki; Founder, Carbon Conscience; and Co-Chair, ASLA Climate Action Committee Subcommittee on Climate Drawdown and Biodiversity, has also focused on helping landscape architects do more good.

He is interested in increasing the “climate literacy” of landscape architects. This is crucial because “developers and clients increasingly expect it.”

Hardy led the development of Sasaki’s Carbon Conscience tool to help landscape architects, architects, planners, and others better understand the climate impacts of their design proposals. It’s for early phase design work when there is the greatest opportunity to reduce carbon and increase sequestration.

He wants to see more analysis of site carbon opportunities woven into projects, shifting from a model of whole building lifecycle assessments to whole site lifecycle assessments.

“There are lost opportunities if we don’t factor in the landscape. For example, California’s updated building code, which regulates embodied carbon in buildings, ignores biogenic carbon in the landscape.”

“We need to expand the spatial boundaries of lifecycle assessments. The living environment is the only viable way to sequester carbon,” Hardy said.

But he also cautioned that “not all sites and not all ecosystems are equal.” This is why it’s important to work with a landscape architect to figure out the carbon storage potential of a site.

The Sustainable SITES Initiative (SITES) is another tool for reducing emissions and increasing sequestration in the landscape, said Danielle Pieranunzi, SITES Director, Green Business Certification Inc. (GBCI). “70 percent of SITES credits contribute to improving carbon drawdown.”

SITES is similar to LEED but is designed for landscapes that may or may not have buildings. Now, 336 projects in 41 states and D.C. and 20 countries, spanning over 1.2 billion square feet, participate in SITES.

The U.S. General Services Administration, which manages federal buildings, has required SITES certification for its projects. The State of Rhode Island and recently the City of Austin, Texas followed suit.

“SITES requires an integrative design process, which creates an opportunity to be climate and nature positive,” Pieranunzi said. She noted how the ASLA Climate Action Plan builds from SITES and is closely aligned with its goals.

“SITES shows how important soils and plants are. It’s also about reducing embodied carbon, conserving what is healthy and functional, and restoring landscapes.”

Almiñana shared other projects by his firm that show how landscape architects can increase carbon sequestration.

For the Greenville Courthouse in Greenville, Mississippi, Andropogon increased the diversity and quantity of trees and plants in their design proposal.

Using Climate Positive Design‘s Pathfinder tool, they were able to increase carbon sequestration through the landscape and modify materials so that it would take 32 years to reach a climate-positive state — in which more carbon is stored than emitted.

For the new net water- and energy-positive Yale Divinity School Living Village in New Haven, Connecticut — which is also being certified as part of the Living Building Challenge — they planted more than 230 new trees and significantly increased permeable surfaces. “We doubled the landscape’s capacity to sequester carbon.”

*Almiñana noted that the name of the Central Park neighborhood was changed from the Stapleton neighborhood in 2021. The community had been named after the decommissioned Stapelton airport that once comprised the site, which in turn was named after former Denver Mayor Benjamin F. Stapleton. Community association members voted to change the name of the community after learning Mayor Stapleton had been a member of Klu Klux Klan in the 1920s and in the wake of protests after the murder of George Floyd. The Denver City Council unanimously approved the name change.

ASLA Releases Comprehensive Conversation Guide with Questions on Product Materials, Manufacturing, and More.

ASLA and the ASLA Fund have released Collaborating with Industry Partners on Climate Action and Biodiversity: A Guide to Conversations Among Landscape Architects, Vendors, and Product Manufacturers.

The ASLA Climate Action Committee and Corporate Member Committee curated more than 70 questions landscape architects can ask vendors and product manufacturers about:

  • Product:
    • Carbon data
    • Low-carbon material content
    • Recycled material content
    • Hazardous material content
    • Biodiversity protections
  • Use of products in landscapes
  • Location of product manufacturing
  • Manufacturing facilities
  • Company operations
  • Equity programs
  • Advocacy efforts

There are also additional questions for plant and tree nurseries.

The guide was jointly authored by landscape architects, vendors, and product manufacturers. It incorporates goals outlined in the ASLA Climate Action Plan and Field Guide, the Sustainable Sites Initiative (SITES), and by the International Living Future Institute (ILFI).

“With this guide in hand, landscape architects can ask industry partners the right questions and move the conversation forward. Getting on the same page will lead to deeper collaboration on how to reduce our collective impacts and improve benefits,” said ASLA CEO Torey Carter-Conneen.

“The guide will enable us to expand the dialogue on embodied carbon in materials, the sustainable use of products in landscapes, and supporting equity goals in communities,” said April Phillips, FASLA, Chair, ASLA Climate Action Committee.
