Some other #WLAM2022 highlights: At Ball State University, landscape architecture students explored the topic through a classroom assignment. Kansas State University highlighted how attending LABash 2022 at Louisiana State University allowed their team to connect with landscape architecture professionals and students from across the country.
A Green New Deal means designers can live up to their potential to address the wicked problems of our time. Landscape architects, planners, and architects may be familiar with the Green New Deal Superstudio, which was a call for designers to “spatially manifest” the Green New Deal, or to imagine projects centering jobs, justice and decarbonization.
The Superstudio marks an inflection point for landscape architecture. Grounded in policy and the context of climate change and social unrest, the Superstudio is the landscape architecture community’s public acknowledgement that our work is deeply intertwined with politics.
As a collective of young practitioners, we understand the significance of the Green New Deal conversation happening within and outside of our profession. ASLA and the Landscape Architecture Foundation (LAF) have embraced the Green New Deal, and organized students and practitioners to imagine its tangible implications within the built environment. These steps represent real action towards the shift in practice that Billy Fleming, ASLA, the Wilks Family Director at the McHarg Center at the University of Pennsylvania, called for in his 2019 article, Design and the Green New Deal. Like Fleming and the profession’s organizations, we recognize a shift that needs to happen if landscape architecture is to stand a chance.
It is crucial for landscape architecture to change if we are to have a meaningful contribution toward a habitable future. As Superstudio participants, Wkshp, a team of emerging professionals, viewed the Superstudio as a way to imagine both future projects and adapted practice.
For us, the Superstudio was fulfilling in several ways. With limited experience in professional practice, we found a shared sentiment that our professional experiences were not in complete alignment with what we were sold in school – a sometimes romanticized version of our personal career paths and the impact they will have. After a couple of years in practice, we have maintained faith in the potential of landscape architecture to make large-scale change. Perhaps the most significant aspect of the Superstudio was that it prompted us to make space to rekindle our passions and sense of purpose, in ways that often don’t fit into typical modes of practice.
What exactly doesn’t fit into existing practice and why? While developing our Superstudio submission, our time was dedicated to identifying barriers to implementation and asking questions. Repeatedly, we were brought back to the same power dilemmas, which are beyond the scope of the typical landscape architecture project, but were centered in our Superstudio work: structural racism, a patriarchal society, colonialism, severe economic inequity, and environmental injustice, among others.
Working under the framework of the Green New Deal was liberating – it meant that we could transcend the constraints of the current market, and a model of practice formulated to serve it. It allowed us to imagine design processes and projects to serve geographies and communities that have been economically, socially, and environmentally abandoned, while considering how we can work differently.
We imagine a culture that has moved beyond megalomania, utopianism, and individualism. In the Superstudio, we find the seeds of a collaborative realism and inclusive organizing that we are now working to scale and ground. So, a Green New Deal project is not necessarily a “new project” in its built form, but the where, how, and for whom represent a practice transformed. The Green New Deal creates living infrastructure in places that need it but can’t afford it, repairing landscapes that have been endlessly extracted from, preparing underserved communities for unpredictable futures, with an emphasis that it will all be co-designed. This is a new means and mode of practice — one of which does not yet exist, but desperately needs to.
The Superstudio was an experiment in process, just as much as it was a design project. wkshp/bluemarble, a non-hierarchical collective with collaborators from multiple firms working together across three time zones, embodied this ethos throughout. We understand that ethics of flexible leadership and constant growth are critical for facing the challenges of our generation.
The Modernist approach exemplified by architects Le Corbusier and Frank Lloyd Wright is a deeply flawed, failed model. We cannot rely on individuals to save the planet. In the same vein, we must stop placing individuals on a pedestal within design culture as a whole. Almost nothing in our field is created — or even conceived — by a single individual, and it’s time to acknowledge the power of a team as well as elevate the power of the ideas, rather than praise a single person. On this note, we reject destructive criticism by those in power within our tiny profession. Young designers need support, especially those willing to dedicate a career (or even one year as a thought experiment) to re-conceiving our collective future.
With this transformational spirit, the Superstudio summit, Grounding the Green New Deal, was an opportunity to begin imagining next steps with fellow Superstudio participants and leaders. The summit organized by LAF, with the University of Pennsylvania, Columbia University, ASLA, and the Council of Educators in Landscape Architecture (CELA) at the National Building Museum in Washington, D.C., featured a curated selection of projects and speakers from practice, policy, and advocacy. The summit which was thought-provoking, informative, and beautifully executed, igniting a series of deep reflections.
Both the immediate and more distant futures of the profession were on display at the summit. For those seeking spark notes on advancing jobs justice and decarbonization, here are some general themes we came away with:
Connect with and lend support to organizers, center the visions of frontline communities, and grapple with and address the relationship between ourselves, our communities, and our professions to colonialism, racism, and structural inequalities.
Gain a better understanding of both power and implementation pathways, both locally and nationally, so you can make things happen now.
Concurrently work to advance policies like the GND that aim to create change at scale in the future, work to change institutions that hold power, and when working with developers and politicians make them think that your transformative idea is their idea.
Above all, to make a real impact, we need to get organized and plan our actions.
We were especially inspired by the work and vision of organizers such as Colette Pichon Battle, Esq., the executive director of Gulf Coast Center for Law & Policy, an organization that is actively bringing justice to front line communities in the Gulf Coast Region, and represents the type of organization that designers could support in projects akin to the Green New Deal. The voices of those with public sector experience stood out as well, such as Mitchell Silver, Hon. ASLA, former Commissioner of New York City Parks & Recreation department. These panelists shared their strategies of working within existing institutions to produce projects embodying the pace, scale, and justice-orientation of the Green New Deal in the now.
Kate Orff, FASLA, founder of SCAPE, and Fleming, both key figures in the Superstudio and the profession at large, provided essential framing through presentations that served as a prompt for advocacy and guide for implementation.
We felt that the lack of organized dialogue among the mass of Superstudio participants was a missed opportunity, and that the format of the summit, while inspiring, felt devoid of the popular, inclusive spirit of the Superstudio. Some challenges – mostly of the “how do I start doing this right now?” variety – still need further testing in the real world. For example, once we connect with community organizers, are we prepared to work differently from our normal practice? Can this work happen at scale outside of academic spaces? How does this work get done where there isn’t an existing implementation structure, or the structure cannot transcend existing forms of development? How do we scale up this transformative practice outside of the most populous, resource-rich regions of the country?
Urgency is in the air. The summit must be the beginning of a conversation, yes, but most importantly must further contribute to radical action both within and beyond the field locally and globally. Now is the time for landscape architecture to evolve.
Here are our next steps: capacity building, organizing, and, most critically, doubling down on the collective imagination that the Superstudio so radically and meaningfully engaged.
wkshp/bluemarble is a team of emerging professionals working for transformations within practice and the world at large.
This new future must be envisioned quickly, Orff argued, because humanity has “already crossed the 1.5 C temperature increase” that will unleash destructive climate impacts. “We need to anticipate that future and act now.” And referring to the first panel of the summit, she argued that while interest in climate justice is expanding and designers are partnering with more marginalized communities, landscape architects must accelerate efforts to “co-create, co-facilitate, and co-repair.”
At the same time, Orff cautioned that landscape architecture projects take a long time. “Ten years is nothing in the built environment.” There is simply no time to build new institutions from scratch to address the climate and biodiversity crises. “We must work within the parameters that exist. Given the timescale, we must advocate for radical change within the institutions we have.” She called for “moving fast, but at the speed of trust.”
In a panel discussion, a mix of landscape architects, philanthropists, policymakers, and planners then delved into how to advance decarbonization, jobs, and justice through landscape architecture practice. These are the three tenets of the 2019 Green New Deal Congressional legislative proposal and the Superstudio organized by LAF, the University of Pennsylvania, Columbia University, ASLA, and the Council of Educators in Landscape Architecture (CELA).
Alexa Bush, a program officer with the Kresge Foundation’s Detroit office, who also has a master’s of landscape architecture degree from the University of Virginia, said she shifted from project work at firms to the Detroit city government and then to the foundation sector, because “decision making happens at the local level. How do I enable design? It’s through local government.” And with the philanthropic sector, which works closely with local governments, “it’s about assembling a blend of funds and partners. We can help make the tables where decisions happen.”
She added that “the strength of landscape architects is system thinking. I can call in experts when needed. Landscape architects are the glue in the system and can build the team.”
For Kevin Bush (not related to Alexa), deputy assistant secretary for grant programs at the U.S. Department of Housing and Urban Development (HUD), one of the best ways for landscape architects to advance their ambitious policy goals is to “glob onto existing local projects.”
The reality, he argued, is that “local governments are having the worst time in history.” Overrun with demands related to COVID-19, many local governments face major challenges in planning for long-term climate adaptation. “Design professions should be empathetic about the constrained realities.”
It’s important to find what funds are coming through state and federal pipelines to local projects and “latch onto them.” Otherwise, landscape architects can spend decades planning visionary projects that may not come to fruition.
“To design for other people’s problems we need to speak other people’s languages. When we talk about housing, we shouldn’t say units, but homes,” argued Jess Zimbabwe, executive director of Environmental Works in Seattle. “When the teamsters went on strike here in Seattle, there was widespread irritation at them among design professionals. But if they had living wages and affordable housing, we wouldn’t have these problems.”
Mitchell Silver, Hon. ASLA, former commissioner of New York City Parks & Recreation and now a vice president with McAdams, said that in the aftermath of the murder of George Floyd and in the midst of the Black Lives Matter movement, he was often asked: “How are you doing? What can I do to help?”
He said the most important step landscape architects, planners, and other designers can take is to listen. Planners and designers are tasked with creating places of healing and joy. But that is impossible without “deep understanding.” Anytime he visits any place, he always checks in with himself. “Do I feel welcome? If I don’t, I won’t come back.” Designers have to get this right for more people.
“When working with African American communities, it’s really important to listen,” said Mia Lehrer, FASLA, founder of Studio-MLA. She said her firm is a highly inclusive office, with multiple cultures represented. The past year has been a “charged, emotional time for everyone.” But she feels that as a landscape architect, “it’s important to give back; it’s an obligation.”
Lehrer described how her complex, multi-functional projects, like the new SoFi Stadium in Inglewood, California, are a result of deliberative processes. The stadium, which leveraged a public-private partnership to create a 6-acre lake and 50-acre park, was led by Inglewood Mayor James T. Butts. “There was never more than 12 people in any meeting.” Meetings were designed so that each person could bring up issues to resolve; and then future meetings would resolve new issues.
At the local level, “if you think something is important, than the process needs to be simplified,” Silver said. As part of New York City’s Community Parks Initiative, the city’s equitable parks plan, Silver’s department completed 850 projects in seven years, redesigning parks in underserved communities. “Our goal was to streamline projects.”
To further break down fragmented, siloed government, Silver also called for cities to create a “czar of the public realm” who can cross all departments that impact citizens. And climate-related infrastructure should be governed by a senior role. Resilience should be overarching. “Fragmented government leads to fragmented results.”
“We must also look beyond borders.” Climate, ecological, and biodiversity issues cross governmental jurisdictions, Lehrer argued, and require new coalitions of local organizations. She thought the focus of the Green New Deal Superstudio was too U.S. centric.
In closing remarks, Billy Fleming, ASLA, the Wilks Family Director at the McHarg Center at the University of Pennsylvania, and Roxanne Blackwell, Hon. ASLA, director of governmental affairs at ASLA, noted that positive change takes time, particularly at the national level, but landscape architects have had significant wins.
“30 to 50 years ago, the idea of green infrastructure for stormwater management was a foreign idea,” Fleming said. “Not many years ago, the idea of Complete Streets was radical,” Blackwell argued. “But with persistence and patience,” landscape architects have advanced their policy goals. The recently passed Infrastructure Investment & Jobs Act is a prime example, with hundreds of billions for green infrastructure and water management, bicycle and pedestrian infrastructure, and public lands.
A key way forward for landscape architects is to move from a “transactional to a transformational approach” with communities, argued Kofi Boone, FASLA, professor of landscape architecture and environmental planning at NC State University. “Local knowledge is enriching and yields different kinds of projects and ideas that can lead to innovation.”
A Quiet Revolution: Southwest Cities Learn to Thrive Amid Drought — 04/26/2022, Yale Environment 360
“Facing a changing climate, southwestern U.S. cities such as San Diego, Phoenix, and Las Vegas have embraced a host of innovative strategies for conserving and sourcing water, providing these metropolitan areas with ample water supplies to support their growing populations.”
Parched Southern California Takes Unprecedented Step of Restricting Outdoor Watering — 04/26/2022, The Guardian
“Metropolitan water district of southern California’s resolution will limit outdoor watering to just one day per week for district residents supplied by a stressed system of canals, pipelines, reservoirs and hydroelectric power plants called the State Water Project, which supplies water from the Sacramento-San Joaquin River Delta to 27 million Californians and 750,000 acres of farmland.”
“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.”
Richard J. Weller, ASLA, is the Meyerson Chair of Urbanism and Professor and Chair of landscape architecture and Executive Director of the McHarg Center at The University of Pennsylvania. He is author of seven books, including the forthcoming The Landscape Project, a collection of essays by the faculty at the Weitzman School of Design. He is also the creative director of LA+, the interdisciplinary journal of landscape architecture. In 2017 and 2018, Weller was voted by the Design Intelligence survey as one of North America’s most admired teachers, and his research has been published by Scientific American and National Geographic and exhibited in major museums around the world.
Later this year, the parties to the Convention on Biological Diversity (CBD) will meet in China to finalize what is being called a “Paris Agreement for Nature.” The agreement will outline global goals for ecosystem conservation and restoration for the next decade, which may include preserving 30 percent of lands, coastal areas, and oceans by 2030. Goals could also include restoring one-fifth of the world’s degraded ecosystems and cutting billions in subsidies that hurt the environment. What are the top three things planning and design professions can do to help local, state, and national governments worldwide achieve these goals?
Design, Design, and Design!
There are now legions of policy people and bureaucrats, even accountants at the World Bank, all preaching green infrastructure and nature-based solutions. But the one thing all these recent converts to landscape architecture cannot do is design places. They cannot give form to the values they all now routinely espouse.
But design is not easy, especially if it’s seeking to work seriously with biodiversity, let alone decarbonization and social justice. Design has to show how biodiversity— from microbes to mammals— can be integrated into the site scale, then connected with and nested into the district scale, the regional, the national, and, ultimately, the planetary scale. And then it has to situate the human in that network – not just as voyeurs in photoshop, but as active agents in ecosystem construction and reconstruction.
Of course, wherever we can gain influence, this is a matter of planning — green space here, development there. But it’s also an aesthetic issue of creating places and experiences from which the human is, respectfully, now decentered, and the plenitude of other life forms foregrounded.
It’s as if on the occasion of the sixth extinction, we need a new language of design that is not just about optimizing landscape as a machine, or a pretty picture, but that engenders deeper empathy for all living things and the precarious nature of our interdependence.
In 2010, the CBD set 20 ambitious targets, including preserving 17 percent of terrestrial and inland waters and 10 percent of coastal and marine areas by 2020. Of these targets, only 6 have been partially met. On the other hand, almost every week, we hear about billions being spent by coalitions of foundations or wealthy individuals to buy and protect vast swathes of land in perpetuity. And the protection of nature and leveraging “nature-based solutions” is increasingly a global priority. Are you positive or negative about the future of conservation?
In 1962, there were about 9,000 protected areas. Today, there are over 265,000 and counting. If our yardstick is humans setting aside land for things other than their own consumption, then there is reason to be optimistic.
In 2021, the total protected area sits at 16.6 percent the Earth’s terrestrial ice-free surface, not quite 17 percent, but close. The missing 0.4 percent is not nothing – it’s about 150,000 Central Parks and over the last few years my research has been motivated by wondering where exactly those parks should be.
The fact that humans would give up almost a fifth of the Earth during such a historical growth period is remarkable in and of itself. While targets are useful political tools, the question is one of quality not just quantity. And that’s where pessimism can and should set in. Protected areas, especially in parts of the world where they are most needed, arise from messy, not to say corrupt, political processes. They are not always a rational overlay on where the world’s most threatened biodiversity is or what those species really need.
The percentages of protected areas around the world are also very uneven across the 193 nations who are party to the Convention. Some nations, like say New Zealand, exceed the 17 percent target, while others, like Brazil fall way short – and they don’t want people making maps showing the fact. Protected areas also have a history of poor management, and they have, in some cases, evicted, excluded, or patronized indigenous peoples.
Protected areas are also highly fragmented, which is really not good for species now trying to find pathways to adapt to climate change and urbanization and industrialization. The global conservation community is keenly aware of all this but again, while they are good on the science and the politics, they need help creating spatial strategies that can serve multiple, competing constituencies. Under the Convention, all nations must produce national biodiversity plans, and these should go down to the city scale, but these so-called plans are often just wordy documents full of UN speak. There is a major opportunity here for landscape architects to step up.
So, the pessimist’s map of the world shows the relentless, parasitical spread of human expansion and a fragmented and depleted archipelago of protected areas. The optimist’s map on the other hand shows over 160 projects around the world today where communities, governments, and non-governmental organizations (NGOs) are reconstructing ecosystems at an epic landscape scale.
Rob Levinthal, a PhD candidate at Penn and I call these Mega-Eco Projects. As indicators of the shift from the old-school engineering of megastructures towards green infrastructure on a planetary scale, they are profoundly optimistic.
We don’t call these projects Nature Based Solutions. The reason being that “nature” comes with way too much baggage and “solution” makes designing ecosystems sound like a simple fix. These two words reinforce a dualistic and instrumentalist approach, things which arguably got us into the mess we find ourselves in today.
By placing the Mega-Eco Projects within the tradition of 20th century megaprojects — many of which failed socially and environmentally, if not economically, we are taking a critical approach to their emergence, which is important to working out what really makes for best practice as opposed to just greenwashing.
Whereas the definition of old school megaprojects was always financial — say over a billion dollars — our working definition of Mega-Eco Projects is not numerical. Rather, it is that they are “complex, multifunctional, landscape-scale environmental restoration and construction endeavors that aim to help biodiversity and communities adapt to climate change.”
Furthermore, unlike the old concrete megaprojects, Mega-Eco Projects use living materials; they cross multiple site boundaries, they change over time, and they are as much bottom up as top down. The project narratives are also different, whereas megaprojects were always couched in terms of modern progress and nation building, the Mega-Ecos are about resilience, sustainability, and a sense of planetary accountability.
There are four categories of Mega-Ecos. The first are large-scale conservation projects; the second are projects that seek to resist desertification; the third are watershed plans; and the fourth are green infrastructure projects in cities either dealing with retrofitting existing urbanity or urban growth.
As you would expect, landscape architects tend to be involved with this fourth category, but there is a bigger future for the field in the other three, which is part of our motivation for studying them.
By our current assessment, there are about 40 Mega-Eco Projects taking place in metropolitan areas around the world today. These tend to be in the global north and China, notably the Sponge Cities initiative, where so far over $12 billion has been spent in 30 trial cities. We have not yet conducted a comparative analysis of these projects, nor are many of them advanced enough to yet know if they are, or will be, successful.
With specific regard to urban biodiversity, I don’t think there is yet a city in the world that really stands out and has taken a substantial city-wide approach that has resulted in design innovation. It will happen. As they do with culture, cities will soon compete to be the most biodiverse. The conception that cities are ecosystems, and that cities could be incubators for more than human life is a major shift in thinking, and while landscape architecture has a strong history of working with people and plants, it has almost completely overlooked the animal as a subject of design. That said, we shouldn’t romanticize the city as an Ark or a Garden of Eden. The city is primarily a human ecology, and the real problem of biodiversity lies well beyond the city’s built form. Where cities impact biodiversity is through their planetary supply chains, so they need to be brought within the purview of design.
Singapore is a case in point. Because it developed the Biodiversity Index, Singapore has been able to tally its improvements with regard to urban biodiversity and tout itself as a leader in this area. Many other cities are adopting this tool and this is good.
But this is also where things get tricky, because whatever gains Singapore can afford to make in its urban biodiversity need to be seen in light of the nation’s massive ecological footprint.
I mean, Singapore can make itself into a garden because the farm and the mine are always somewhere else. I would call Singapore a case of Gucci biodiversity, a distraction from the fact that they bankroll palm oil plantations in Kalimantan, the last of the world’s great rainforests.
That said, every city is shot through with contradictions. The question then is to what degree do the designers play along or whether they can make these contradictions the subject of their work, as opposed to its dirty little secret. The Gardens by the Bay project, for example, is a brilliant case of creating a spectacle and keeping tourists in town for an extra day, but it’s got nothing to do with biodiversity beyond the boundary of the project.
The late E.O. Wilson and other biologists and ecologists have also called for protecting half the Earth’s lands and oceans. The UN Intergovernmental Panel on Climate Change (IPCC) split the difference in their recent report, calling for 30-50 percent to be protected. What are the extra benefits to protecting 50 percent? What does this mean for the planning and design of existing and future human settlements?
I’d trust E.O. Wilson or better still, James Lovelock, with the calculation for a healthy planet, but the dualism of humans here and biodiversity over there that tends to come with Wilson’s notoriously puritanical position is problematic.
The world is a novel, highly integrated, human dominated ecosystem, and design has to work at improving the symbiotic nature of that condition. Each site needs to be assessed on its own biological and cultural terms as to what can be more deeply integrated or what should be separated out; what has to be actively curated and what can be left to its own devices. As Sean Burkholder and others have pointed out, this means designing time as well as space.
The thing with Wilson is where exactly would his 50 percent be? He never really explained it in spatially explicit terms. Half Earth means another 34.5 percent on top of what we currently have protected. As a priority, it would have to comprise any unprotected forest or other areas of remnant vegetation and whatever can be clawed back in the world’s biodiversity hotspots.
But the numbers don’t really add up. About 40 percent of the Earth’s ice-free earth is currently used for food production, 30 percent is desert, and 30 percent is forest – although “forest” is a loose term, and some of that already overlaps with protected areas. Given that the global foodscape is and will probably continue expanding, 30 percent total protected area seems more reasonable than 50. It is my belief that design, if given the chance, can weave viable biodiversity through the contemporary agricultural landscape whilst maintaining overall yield.
Even 30 seems a stretch, because if you project the expansion of crop land by 21st century population growth, we need most of the planet to feed people, so something has to give. Either we massively increase yields from the current agricultural footprint or biodiversity gets pushed further into the mountains. Or billions starve. The prospect of us reducing the planet to a monoculture is very real and very scary on every level.
To your question, the benefits would be that by more or less doubling the current conservation estate, we could create larger patches in the hotspots and seek to achieve connectivity between the existing fragments of protected areas. As landscape ecology teaches, it is only with larger patches and substantial connectivity that we can create a truly resilient and healthy landscape. The problem is of course that the patches and corridors have to be reverse engineered into hostile territory. Human settlements and agriculture have to make way for larger patches and greater connectivity and planned around it. To turn the whole thing on its head, human settlements and human land uses have to protect the global conservation estate. Easy to say.
Biodiversity loss is often considered a result of the climate crisis. But there are other issues also driving increased biodiversity loss and extinction rates worldwide, such as increased development in natural areas, the spread of transportation systems, and pesticide and chemical use. How do explain the relationship between climate change and biodiversity loss?
When people hear “biodiversity” they almost invariably think of charismatic megafauna, but as you indicate, the problem runs deeper and at a much finer grain. Of course, we are now obsessed with chasing every carbon molecule, but for life on and in the land and its waters, the problem is also excess manufactured nitrogen along with other toxins. Ironically, despite ultimately killing microorganisms upon which soil health depends, industrialized fertilizers have slowed the rate of deforestation that would have occurred had the world tried to feed itself without industrial fertilizers because they have, at least in the short term, increased yields.
The main problem from a spatial planning and land use perspective is that species increasingly need to migrate so as to adapt to a changing climate but they find themselves trapped in isolated fragments of protected areas or stranded in unprotected scraps of remnant habit.
There is another part of this though, and that is that the entire discourse and politics of environmentalism is couched in terms of loss. But a truer picture perhaps is that as ever in the chaos of evolution, there will be winners as well as losers. I don’t think we know what is really happening or what will happen, so in that sense we need to design landscapes as insurance policies, as expressions of the precautionary principle where we just try to maximize the potential of life to evolve. In this regard landscape architectural research and design becomes less about finished projects, and more about conducting experiments based on both scientific and cultural questions related to biodiversity.
The Metatron at the Theoretical and Experimental Ecology Station in Moulis, France is a good example. The Metatron is an experimental field of 48 enclosures in which species composition, temperature, light and humidity can be controlled. Each enclosure is connected to the others via small passages that can also be controlled. In this way, the Metatron is a simulator of landscape dynamics, a model microcosm in which each enclosure is understood as a “patch” and each connector a small simulation of a landscape “corridor.” Since 2015, given the limitations of its size, experiments have focused on studying how small species like butterflies and lizards move through the system, but many more species could be studied using a similar system at larger scales. In essence, the Metratron is learner’s kit, helping us understand how best to reconstruct landscapes at scale.
Your own research, including the ASLA-award winning Atlas for the End of the World, documents how areas at the edge of sprawling cities around the world are increasingly colliding with biodiversity hotspots, which are defined as highly valuable reservoirs of diverse and endemic species. What are the implications of your research?
By conducting an audit of land use and urban growth with regards to CBD targets in the world’s biodiversity hotspots, the Atlas set the scene for my two current research projects.
The first is the Hotspot Cities Project and the second is the World Park Project. A hotspot city is a growing city in a biodiversity hotspot – the 36 regions on Earth where endemic biodiversity is most diverse and most threatened. We’ve identified which of these cities —over 90 percent— are sprawling on direct collision courses with remnant habitat harboring endangered species.
In our mapping we identify the conflict zones between development and biodiversity and then we conduct design case studies as to how the conflict could be mitigated. The argument is that destructive sprawl is not a fait accompli, and designers—especially landscape architects skilled in urban design— can create credible alternatives by taking a holistic, city-wide perspective. This research especially draws attention to peri-urban landscapes that are largely overlooked by the profession, because the design dollar has mainly been invested in city centers.
The World Park Project is a big vision for a new form of conservation landscape, one that actively involves humans in its construction. It’s an answer to the question of where those 150,000 Central Parks should be, as I mentioned earlier.
The idea of the World Park begins with the creation of three recreational trails: the first from Australia to Morocco, the second from Turkey to Namibia, and the third from Alaska to Patagonia.
Passing through 55 nations, these trails are routed to string together as many fragments of protected areas in as many hotspots as possible. The trails are catalysts for bringing people together to work on restoring the ecological health of over 160,000 square kilometers of degraded land in between existing protected areas.
In this way, the Park is about building a coherent and contiguous global network of protected area. It addresses the two biggest challenges facing global conservation today: ensuring adequate representation of biodiversity in protected areas and connectivity between those areas. It sounds crazy, but forging connectivity at this scale is just what we do for every other form of global infrastructure. Humans build networks, and it’s high time to build a green one.
I was expecting derision from design academics about World Park, because “going big” is generally seen as neo-colonial or megalomaniacal. I was also expecting world weary eye-rolling from the conservationists or outright rejection of the idea because it would suck the oxygen out of their own efforts, but generally the reaction has been very positive.
Most people, particularly in the NGOs, have reacted like “wow – this is exactly what we need right now.” They know they can’t just keep adding more fenced-off fragments of protected area to meet UN targets. There are now so many conservation efforts going on but they are all disconnected from one another. A World Park could galvanize these efforts into something that is greater than just the sum of its parts.
In any event, my research team (Alice Bell, Oliver Atwood and Elliot Bullen) have completed the mapping of the Park’s territory. Now I’m talking with UNESCO about how we might move the idea to a proper feasibility study. Realistically, nothing will happen unless the major NGOs adopt it, along with some philanthropic champions and the relevant ministers in those nations whose sovereign territory is involved.
Only half-jokingly, I think Jeff Bezos, Elon Musk, and Richard Branson should bring their toys back to earth and take this on. Musk could fund the African trail, Bezos the Americas, and Branson would pick up the Australia to Morocco piece. At current landscape restoration rates, I worked it out at about $7 billion.
That’s an expensive park, but the better question to ask is not what it costs but what is it worth? For a mere $7 billion a World Park could provide investment in impoverished landscapes. It could provide meaningful experiences and jobs for lots of people. Above all, it would be a profound sign of hope that humanity can work together to be a constructive force of nature instead of its executioner.
Lastly, how can landscape architecture academics and practitioners better partner to address the twinned biodiversity and climate crises? What additional research is needed to better weave biodiversity considerations into broader climate solutions?
Well, as someone who has spent a lifetime in both the academy and practice, I would really like to take this opportunity to attest to the value of both. I think it’s a problem that the academy demands young faculty have PhDs but not necessarily any practice experience. Just as I think it’s a problem that certain elements of the profession become anti-intellectual over time and associate this with being savvy professionals.
Academics have the luxury of formulating research questions and methods, whereas practitioners are generally making it up on the run and learning by doing. These are both entirely valid ways of forming knowledge, and they actually need each other.
My work over the last decade has been very big picture, but it means nothing unless it can translate into design. So I think there are two forms of design needed right now with regard to biodiversity and they both bring academics and practitioners together.
The first is taking on a whole-of-city scale and considering the city as an incubator and protectorate for biodiversity and offer plausible scenarios as to how the city’s growth can be best managed to minimize negative impact on existing biodiversity. Until city authorities pay properly for this work, the academics have to act as the start-ups. They can form interdisciplinary teams to find research funding to do this work, preparing the way, as it were, for practitioners to come in and realize specific projects.
Which brings us to the second form of design — the project scale. Take any project at any scale and ask how to approach it if your client was every living thing, not just humans, and then work as if your life really depended on serving all of them – which, incidentally, it does! To answer this takes both time and levels of knowledge beyond landscape architects irrespective of whether they are in the academy or in practice. We are very accomplished at designing for humans but still have everything to learn if we consider biodiversity as our client.
In terms of both professional and academic practice, the role of the landscape architect, now more than ever, is to bring the world of development and the world of conservation together over the same maps and serve as a negotiator.
It sounds like a platitude, but it goes to the core of our job description, and it’s never been more important. There has never been more at stake.
The day we’ve been waiting for — Olmsted’s 200th birthday on April 26 — is almost here, and we couldn’t be more excited to reflect on Olmsted’s living legacy and usher in the next 200 years of parks for all people.
As we prepare to #CelebrateOlmsted, the campaign needs help showing the depth and breadth of Olmsted’s fan base. The National Association of Olmsted Parks (NAOP) and the Olmsted 200 campaign are crowdsourcing birthday wishes for Frederick Law Olmsted’s special day.
In the form of short video submissions, we are asking ASLA chapters and chapter members to send birthday messages in honor of this monumental occasion. Record a message alone, film it with a friend, or get the entire chapter or office involved — the possibilities are endless! Videos will be collected and included in a special birthday project. The deadline to submit is April 21.
We also hope that you’ll join us in-person! Next week, Olmsted 200 will be in New York to #CelebrateOlmsted with our founders, partners, and friends. If you happen to be in the city, please join us for park tours and other programming happening in Manhattan and throughout the other boroughs.
The website also includes a lively blog, Shared Spaces, which features many new and exciting updates. Olmsted 200 will continue throughout 2022 and is interested in sourcing blog posts from ASLA members willing to share information about local projects, personal reflections, site histories, and more. To submit blog posts, contact Olmsted 200.
New Research Highlights the Role of Green Spaces in Conflict — 04/14/22, University of British Columbia
“Green spaces can promote well-being, but they may not always be benign. Sometimes, they can be a tool for control. That’s the finding of a new paper that analyzed declassified U.S. military documents to explore how U.S. forces used landscapes to fight insurgency during the war in Afghanistan.”
James Corner Field Operations’ Tunnel-topping San Francisco Park Is Set for July Debut — 04/13/22, The Architect’s Newspaper
“Visitors to Presidio Tunnel Tops will find winding cliffside trails, picnic areas, extensive gardens and meadows filled with native vegetation, a 2-acre natural play area for children dubbed the Outpost, and several elevated overlooks offering sweeping city and bridge views. The new swath of parkland will fuse back together the waterfront and Crissy Field, a former air field that now serves as a popular recreation hotspot, with the Presidio’s bustling historic Main Post.”
Why JW Marriott Is Planting Edible Gardens in Every One of Its Hotels — 04/13/22, Fast Company Design
“The terrarium was designed by Lily Kwong, whose eponymous landscape design studio has previously worked with H&M, St-Germain, and the French fashion designer Joseph Altuzarra (who is also her cousin). The terrarium is part of a broader initiative called the JW Garden, for which the hotel chain plants fruits, vegetables, and herbs to use in its kitchen and spas.”
Green Transportation Projects Face Costly, Time-consuming Environmental Reviews — 04/13/22, The San Francisco Examiner
“Transit agencies across California are ready to move forward with more than three dozen green transportation projects, ranging from bus rapid transit lines to bike lanes. But unless the Legislature takes action, these projects could be mired in years of costly, time-consuming analysis and lawsuits on the basis that they are bad for the environment.”
Special Report: U.S. Solar Expansion Stalled by Rural Land-use Protests — 04/07/22, Reuters
“Solar currently makes up 3% of U.S. electricity supply and could reach 45% by 2050 to meet the Biden administration’s goals to eliminate or offset emissions by 2050, according to the Department of Energy. To get there, the U.S. solar industry needs a land area twice the size of Massachusetts, according to DOE. And not any land will do, either. It needs to be flat, dry, sunny, and near transmission infrastructure that will transport its power to market.”
ASLA urges governments to focus on cities and nature to meet climate goals.
The third assessment report of the Intergovernmental Panel on Climate Change (IPCC) — Climate Change 2022: Mitigation of Climate Change — which was created by nearly 300 scientists in 65 countries over the past seven years, finds that cities are a significant contributor to global emissions.
Recent estimates place cities’ share of global emissions at more than 70 percent. With expected population growth, existing and future cities can either be the primary source of future warming or a key solution.
According to the IPCC, if little is done, future cities could contribute 40 billion metric tons of emissions each year by 2050. But by taking important steps starting this decade, that number could reach as low as 3 billion tons.
“Landscape architects are systems designers. We are already designing the next generation of park, transportation, and water infrastructure needed to make this transformation happen. But we need more policymakers to prioritize these changes,” said ASLA President Jeannie Martin, FASLA.
“Landscape architects plan and design walkable environments that are central to reducing urban energy demand and emissions. This work has involved partnering with planning and design professions to pair public transit with transit-oriented development, and integrate Complete Streets, which offer safe, accessible pedestrian and bicycle access, and trails and greenways,” said Torey Carter-Conneen, ASLA CEO.
Designing with nature is also critical to achieving broader urban climate goals. Landscape architects integrate green infrastructure in the form of parks, green roofs, green streets, rain gardens, and bioswales. As the IPCC notes, these strategies not only sequester carbon but also manage stormwater, reduce urban heat islands, increase biodiversity, and improve health and well-being.
“We design cities to include living systems. Landscape architects store carbon by incorporating diverse ecologies into the urban landscape. This also helps cities become more resilient to climate impacts,” said Scott Bishop, ASLA, Chair of the ASLA Climate Action Committee.
The IPCC’s latest report calls for preserving existing ecosystems outside cities that store carbon as well, such as forests, prairies, peatlands, mangroves, and wetlands. But notes that these ecosystems are also increasingly threatened by rising temperatures, wildfires and other climate impacts, and sprawl.
Renewable energy now powers nearly 40 percent of global electricity, with wind and solar now making up 10 percent of the total. The IPCC report finds that since 2010, the cost of solar panels has decreased by 85 percent and wind turbines by more than 50 percent. Still, governments and companies need to spend an estimated $1.8 to 3.6 trillion each year on renewable power, approximately 3-6 times the current amount, to reach climate goals.
Landscape architects can help plan an expansion of wind and solar across our landscapes in a way that supports ecological restoration and provides greater community benefits.
