Each year, the Trust for Public Land (TPL) issues its ParkScore, which ranks the park systems of the 100 most populated cities in the U.S. This year, the organization also explored the positive health outcomes of top-scoring cities, looking at more than 800 innovative programs and practices that integrate park and healthcare systems.
“Our fellows have shown courage, written books, founded mission-driven non-profits, created new coalitions, and disseminated new tools,” said Cindy Sanders, FASLA, CEO of OLIN, in her introduction of the Landscape Architecture Foundation (LAF) Fellowship for Innovation and Leadership program at Arena Stage in Washington, D.C.
Sanders highlighted the results of a five-year assessment of the LAF fellowship program and its efforts to grow the next generation of diverse landscape architecture leaders. The assessment shows that past fellows are shaping the future of the built environment in key public, non-profit, and private sector roles.
In midtown Manhattan, the street crossings surrounding the entrance to the Lincoln Tunnel were once some of the most challenging in the city. A mess of highway ramps, missing sidewalks, and concrete barriers made the corner of Dyer Avenue and 30th Street an area to avoid.
Now with a new $50 million elevated connector, pedestrians can safely move 30 feet above the intersections using a 600-foot-long L-shaped bridge from the High Line to Moynihan Train Hall.
The institution of slavery shaped landscapes on both sides of the Atlantic Ocean. And in turn enslaved and free Africans and their descendants created new landscapes in the United States, the Caribbean, and Sub-Saharan Africa. African people had their own intimate relationships with the land, which enabled them to carve out their own agency and culture.
At Dumbarton Oaks in Washington, D.C., a symposium — Environmental Histories of the Black Atlantic World: Landscape Histories of the African Diaspora — organized by N. D. B. Connolly, a professor at Johns Hopkins University, and Oscar de la Torre, a professor at the University of North Carolina at Charlotte, sought to highlight those forgotten relationships between people and their environment.
This Earth Day, U.S. Vice President Kamala Harris highlighted the many benefits of nature-based solutions and recognized the important role of landscape architects in this work. At the University of Miami, she also announced $562 million in funding for coastal resilience projects, supporting 149 projects in 30 states, through the Climate-Ready Coasts Initiative of the National Oceanic and Atmospheric Administration (NOAA). Vice President Harris’ remarks build on the Biden-Harris administration’s support for planning and designing with ecological systems in an equitable way.
“Economic shocks, climate change, and COVID-19 have changed transportation systems in a fundamental way. We can’t waste a crisis. We can increase access to transportation while reducing greenhouse gas emissions. We can achieve more mobility with fewer impacts,” argued Ani Dasgupta, president of the World Resources Institute (WRI), at the 20th annual Transforming Transportation conference. For two days, global leaders reflected on the state of transportation systems worldwide at the hybrid event in Washington, D.C., which was also watched by tens of thousands online. The event was co-organized by WRI and the World Bank.
Transportation still accounts for 25 percent of greenhouse gas emissions worldwide and up to 30 percent of emissions in developed countries. Transportation is a diverse sector that includes sidewalks, bikes, cars, buses, trains, subways, ships, and planes.
“How do we ensure new parks don’t cause ‘green gentrification,’ which can lead to the exclusion and displacement of underserved communities? How can we ensure we don’t displace the communities that new parks are meant to serve?,” asked Dede Petri, CEO of the Olmsted Network (formerly the National Association of Olmsted Parks), during an Olmsted 200 event.
New parks are meant to be accessible to everyone, but in many urban areas, developer-driven parks mostly attract wealthier Americans. Cities benefit from increased development adjacent to these new parks, bringing in higher tax revenues, but that raises questions about whether these spaces can, in effect, lead to community displacement.
New Orleans experiences the worst urban heat island effect in the country, with temperatures nearly 9 F° higher than nearby natural areas. The city also lost more than 200,000 trees from Hurricane Katrina, dropping its overall tree canopy to just 18.5 percent.
The non-profit organization Sustaining Our Urban Landscape (SOUL) partnered with landscape architects at Spackman Mossop Michaels (SMM) to create a highly accessible, equity-focused reforestation plan for the city that provides a roadmap for achieving a tree canopy of 24 percent by 2040. But more importantly, the plan also seeks to equalize the canopy, so at least 10 percent of all 72 neighborhoods are covered in trees. Currently, more than half of neighborhoods are under the 10 percent goal.
“Seneca Village was an important community. It was 40 acres, two-thirds African American, and had a church and school,” explained Sara Zewde, ASLA, founder of Studio Zewde and assistant professor at the Harvard Graduate School of Design, during a session at the ASLA 2022 Conference on Landscape Architecture in San Francisco.
The 225 residents of Seneca Village were displaced by the New York City government in the mid 1800s to make way for Central Park, which is considered one of the masterpieces of landscape architect Frederick Law Olmsted and architect Calvert Vaux.
“Superstorm Sandy in 2012 was a wake-up call for NYC and made the city realize it needed to better prepare for climate change,” said Adrian Smith, FASLA, vice president at ASLA and team leader of Staten Island capital projects with NYC Parks. Due to storm surges from Sandy, “several people in Staten Island perished, and millions in property damage were sustained.”
On the 10th anniversary of Sandy, Smith, along with Pippa Brashear, ASLA, principal at SCAPE, and Donna Walcavage, FASLA, principal at Stantec, explained how designing with nature can lead to more resilient shoreline communities. During Climate Week NYC, they walked an online crowd of hundreds through two interconnected projects on the southwestern end of the island: Living Breakwaters and its companion on land — the Tottenville Shoreline Protection Project.
A persuasive local advocacy and media campaign convinced the U.S. Army Corps of Engineers to conduct a new, expanded study for a $6 billion project to protect Miami from future hurricanes, coastal flooding, and climate impacts. Critics argued that the Army Corps’ initial draft plan for the project, which had proposed a series of sea walls and gates, would have negatively impacted the character of Miami, reduced property values, and cut-off access to important waterfront parks, exacerbating existing inequities in access to public space.
The need to rapidly adapt to climate change has rightfully taken center stage. But the connections between climate change and stormwater management are often overlooked. Climate change impacts the hydrological cycle by increasing water scarcity and the frequency and intensity of flooding while contaminating waterways. Better managing stormwater is key to managing water resources and protecting our safety and the health of our environment.
“The planning practices of the past are inadequate for today’s challenges,” said David Rouse, ASLA, a landscape architect and planner, at the American Planning Association‘s National Planning Conference in San Diego. Rapid technological change, socio-economic inequities, natural resource depletion, and climate change are forcing planning and design professionals to adapt. “How can the practice of planning evolve to be more sustainable and equitable?”
Tragedy, protest, insurrection, and political turmoil have led to a renewed awareness of racial injustice and democratic instability. These issues create new challenges for users and designers of public spaces in America. Cultural spasms have resulted in contested public spaces — sites of killings, protests in streets and parks, and forgotten burial grounds. These spaces need a new form of environmental justice.
Decades of redlining and urban renewal, rooted in racist planning and design policies, created the conditions for gentrification to occur in American cities. But the primary concern with gentrification today is displacement, which primarily impacts marginalized communities shaped by a history of being denied access to mortgages. At the ASLA 2021 Conference on Landscape Architecture in Nashville, Matthew Williams, ASLA, with the City of Detroit’s planning department, said in his city there are concerns that new green spaces will increase the market value of homes and “price out marginalized communities.” But investment in green space doesn’t necessarily need to lead to displacement. If these projects are led by marginalized communities, they can be embraced.
København (Copenhagen), the capital of Denmark, is at the forefront of many landscape architects and planners’ minds for both its groundbreaking moves towards sustainability and cutting-edge public spaces, bicycle culture, architecture, and food scenes. Having spent a significant amount of time in the city over the last decade, I’ve had the opportunity to begin to get to know the city and its people. One of the striking things about the city, perceptible in even my time there, is its continued trajectory of improvement. A chorus of people working diligently for decades to optimize the city for the everyday lives of its inhabitants have been laying the groundwork for what is possible today.
A new report from The Trust for Public Land (TPL) makes a compelling case for transforming underperforming, paved public schoolyards into green oases for the entire community. While the benefits for schools and their educational communities are clear, TPL sees an opportunity to open up these facilities to surrounding neighborhoods after school hours, on weekends, and when school is out. If all 90,000 public schools in the country had a “community schoolyard,” more communities could tackle the persistent park equity issue — in which too few communities, particularly undeserved ones, enjoy access to nearby high-quality public green spaces. TPL argues that opening up all schoolyards, essentially turning them into part-time all-access community hubs, would “put a park within a 10-minute walk of nearly 20 million people — solving the problem of outdoor access for one-fifth of the nation’s 100 million people who don’t currently have a park close to home.”
A new report from the Intergovernmental Panel on Climate Change (IPCC) states that global warming of 1.5°C (2.7 °F) is essentially inevitable in coming decades. The question now is whether the world can prevent further, more destructive warming of 2°C (3.6°F), or, even worse, 3°C (5.4°F), which is what current policies put us on a trajectory to experience. Our economies can only put another 420 gigatons of greenhouse gas emissions into the atmosphere if we want a good chance of keeping a temperature increase to 1.5°C instead of 2°C. At our current pace, the world’s carbon budget will be used up before 2030. We need to phase out fossil-fuel use, build thousands of new clean power plants -- and swiftly move to power our homes, offices, schools, and transportation systems with clean energy.
