Greenwave, a non-profit organization transforming the fishing industry, was recently awarded the Buckminster Fuller Institute (BFI)’s 2015 challenge, which comes with a $100,000 prize. Greenwave’s winning project is the “world’s first multi-species 3-D ocean farm,” a vertical underwater garden that aims “to restore ocean ecosystems and create jobs in coastal communities by transforming fishers into restorative ocean farmers,” according to BFI. Using simple infrastructure — seaweed, scallops, and mussels growing on floating ropes stacked above clam cages below — Greenwave’s founder Bren Smith has created a low-cost, sustainable system that can be easily replicated by farmers and fishers everywhere.
Drawing comparisons to last years’s BFI challenge winner, Living Breakwaters, the first large-scale experiment with “oyster-tecture” by SCAPE / Landscape Architecture, Smith’s innovative ocean farm was inspired by his time farming oysters in the Long Island Sound. “Here I was a young fisherman, pillaging the oceans in one of the most unsustainable forms of food production on the planet. Aquaculture was supposed to be the great answer to over-fishing, but it turned out to be just as destructive using new technologies. So I became an Oysterman,” Smith said in a Tedx talk.
After Hurricane Sandy and Hurricane Irene destroyed 80 percent of his oyster crop, Smith began to re-envision his farm in order to rebuild it.
Now, a single underwater acre of Greenwave’s flagship farm on the Thimble Islands in New York’s Long Island Sound filters millions of gallons of ocean water each day, creates homes for marine and bird life, and absorbs nitrogen and carbon (the kelp in the farms sequester five times more carbon than land-based agriculture). With zero added inputs, the farm has the capacity to grow 10 tons of sea vegetables and 250,000 shellfish annually on a single acre.
“I went from farming 100 acres down to 20 acres as I began using the full water column. And now I’ve been growing a lot more food on the 20 acres than I was on the 100. Whereas aquaculture is obsessed with growing one thing in one place, we’re growing four kinds of shellfish, two kinds of sea weed, and salt from the 20 acres,” Smith said.
Greenwave will use the $100,000 award to train 25 new farmers on both the East and West coasts of the U.S. with the skills to implement Smith’s ocean farming model. Each of the new farmers “will receive start up grants, free seed, and two years of training and support,” Smith said. “Greenwave will also buy 80 percent of their crop for 5 years at triple the market rate.” The rest of the money will go toward research and development on “kelp-raised beef, and specialty food products.”
Since 2007, BFI has used its annual international competition to highlight paradigm-shifting designs that, in the words of the late Buckminster Fuller, “make the world work for 100 percent of humanity, in the shortest possible time, through spontaneous cooperation, without ecological offense or the disadvantage of anyone.”
This is the second year in a row that the first place winner has “directly addressed urgent and complex issues related to our oceans: the impending collapse of marine ecosystems, the long-term effects of climate change on our coastal communities, and the economic catastrophe these communities are experiencing right now as a result,” said Elizabeth Thompson, executive director of BFI.
This year’s other finalists include:
Algae Systems is a new technology that uses native algae species to capture and treat wastewater. Powered by photosynthesis, the system produces renewable fuels and fertilizers as byproducts, at a lower cost per gallon that alternative wastewater treatment technologies.
