Columbia University professor Dickson Despommier‘s “Vertical Farming” idea has been kicking around for some time now. But for those who haven’t heard of it, it’s a concept that would take traditional indoor, greenhouse-style farming to new heights—skyscraper heights to be exact.

Since brainstorming the idea during a course he taught called “Medical Ecology” almost nine years ago, Despommier has been ardently pushing for large-scale, indoor farms. Last year, he wrote a book, The Vertical Farm: Feeding the World in the 21st Century, but even as late as its publication, the vertical farm concept remained just that, conceptual. But now, there are at least three up-and-running prototype vertical farms around the globe, with more coming soon.

Just before he jetted off to Manchester, England, for the Manchester International Festival where he was to unveil a retrofitted vertical farm project, Despommier stopped by the New York Academy of Science to talk about his “big idea.” Hear the interview in my latest S&C podcast.
