alads of the future may still be served in bowls, but their ingredients might be grown in skyscrapers. That's the hope of scientists and architects who are erecting a unique strategy to feed a swelling population on a planet with finite farmland. "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 highrise 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. "The concept is based on technologies already in use throughout the world, mainly hightech greenhouses," Despommier said. For example, many existing greenhouses use hydroponics, a technique for growing crops in smaller spaces using nutrient-enriched water instead of soil.
