High-Rise Farms: The Future of Food?
John Roach for National Geographic News
June 30, 2009
"In another 40 years, there'll be another three billion people. That's the problem," said Dickson Despommier, a professor of public health at Columbia University in New York. "We have to find another way to feed them."
One solution, Despommier believes, is to grow everything from salad greens to staple grains year-round in high-rise buildings at the hearts of urban centers.
This so-called vertical farming could put food within easy reach for billions of people while reducing carbon emissions from shipping crops across continents and oceans, he notes.
(See pictures of glass pyramids, towers of greenhouse pods, and other possible designs for vertical farms.)
"[The concept] is based on technologies already in use throughout the world, mainly high-tech greenhouses," Despommier said.
