In North Carolina, history, industry, and climate change work in tandem to create landscapes of toxic waste.

FROM THE MAY 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

In Houston, it was the petrochemical plants. In North Carolina, it was the hog farms. In both places, churning floodwaters caused by recent storms were turned into a toxic stew that endangered local water resources and public health. In September 2018, Hurricane Florence made landfall in North Carolina, where seven million gallons of hog waste overtopped the region’s ubiquitous open-air lagoons and quickly made its way into neighbors’ yards and nearby streams.

As by-products go, the fecal sludge of an industrial-scale hog farm is far from benign. The waste can carry viruses, parasites, nitrates, and bacteria such as salmonella. Even in the best circumstances, the odors from these open-air lagoons, which number some 3,300 across the state but are concentrated in the heavily African American counties of eastern North Carolina, are noxious enough that in August 2018 a jury awarded six families $473.5 million for having to live near a hog farm in Pender County. Combined with a severe storm, however, these lagoons become all the more dangerous, threatening the water supply of entire communities and far-flung ecosystems.

Hurricane Florence was just the most recent example of how severe weather events, strengthened by a warming climate, can interact with industrialized landscapes to create new threats to public health and safety. If landscape architects are to grapple with the environmental and human health impacts of climate change, they will have to educate themselves about agricultural waste. (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…)
