The Union of Concerned Scientists’ recent report on the economic damage and displacement that sea-level rise flooding will unleash called for investments “in a range of coastal adaptive measures,” such as “the protection of wetlands, and barrier islands, and other natural flood risk reduction methods” and other “natural infrastructure.” That puts the onus of surviving sea-level rise very clearly on landscape architects.

The report, Underwater: Rising Seas, Chronic Floods, and the Implications for US Coastal Real Estate, which the Union of Concerned Scientists (UCS) compiled with help from the real estate website Zillow, shows the consequences of sea-level rise in the short and long term, down to the state, city, and zip code levels of granularity. Released in June, it estimates lost houses, lost home value, lost tax base, and lost population by the years 2035 and 2100. (more…)

The coffee production industry is a “global economy with a local ecology,” says Francesco Garofalo of the landscape architecture studio Openfabric. The studio has a plan for a coffee-producing region of Peru that would align local cultivation practices with global distribution networks. Openfabric’s “Altitudes” plan steps back from coffee plantation monocultures to spread cash crop risk by encouraging production of a range of foodstuffs. The goal is to create more sustainable cycles of cultivation, production, and distribution.

The plan focuses on the Selva Central region of Peru, east of Lima, which straddles both the Andes and the Amazon River Basin. The local economy is intensely reliant on coffee production, but it’s a fragile and volatile market. Prices surge and plummet on a whim, vulnerable to small climatic shifts that can greatly affect yield. That makes life for the region’s coffee producers precarious.

And lately, temperatures in Selva Central have been rising because of climate change, causing (more…)

Landscape architecture can mitigate carbon emissions, but it is also implicated among the causes.

FROM THE JUNE 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

The Paris Agreement on climate change, created by the consensus of 197 nations, went into effect in November 2016 and has enormous implications for the practice of landscape architecture. If adhered to by its signatories, the agreement signals the end of the fossil fuel era by midcentury, well within the life spans of many landscape architects currently practicing. Though it may seem wonderfully “green,” this energy transition poses profound questions for the practice of landscape architecture at a time when the discipline is needed more than ever.

The Paris Agreement foretells a civilization powered nearly exclusively by renewably generated electricity, not fossil-fueled fire, like today. This will impose severe limits on landscape architecture’s materials, construction methods, and professional mobility. The agreement also portends a society with much less energy overall, as fossil fuels currently make up more than 80 percent of total energy consumed and cannot be easily replaced. These stark realities will challenge landscape architects to adapt to the impending zero-carbon future.

Last year set the record for the hottest year in measured history, breaking 2015’s record, which itself (more…)

São Paolo is a small aquaponics farming settlement where residents and visitors gather medicinal compounds from the surrounding jungle. 2100: A Dystopian Utopia—The City After Climate Change, by Vanessa Keith/StudioTEKA (New York: Urban Research, 2017). Courtesy of Terreform.

In the not-so-distant future, what remains of São Paulo is something like an ecoresort medical crop farm for ewoks. People from all over the world travel to its lush, frequently flooded rain forest and set up shop in ovular pods in the treetops connected by open-air skywalks. They farm fish, grow sugarcane, and harvest rare, medicinal compounds from the surrounding jungle. Crews deconstruct the old city, leaving more room for this life-saving flora to reassert itself.

A continent away, the city of Phoenix, Arizona, is also in the process of unbecoming. Residents of its single-family houses are cannibalizing their neighborhoods at the stern urging of statist security forces. (Let’s say something like United Nations troops, perhaps wearing black helmets instead of blue ones.) The nation’s sixth-largest city will be shrunk to a tiny fraction of its former size to make way for more massive solar energy farms that dominate the desert landscape. Former Arizonans are invited to move themselves along with the bricks and mortar of their communities to a burgeoning megacity in Vancouver. Some people don’t want to go, and are meeting in secret to talk about what to do if they’re forced.

Those companion (but tonally opposed) visions of the future begin with the same book, Vanessa Keith’s 2100: A Dystopian Utopia—The City After Climate Change, published by Terreform’s Urban Research, Michael Sorkin’s publishing imprint. It envisions a world where (more…)
