New Urbanism is an original “Babelgum Our Earth” series exploring transformed spaces, imaginative urban living, and sustainability. In the episode 2, Rooftop Farming investigates how to turn warehouse roofs into city farms and grow local, sustainably produced food. Annie Novak and Ben Flanner have been farming the rooftop of a Brooklyn warehouse since May 2009 and the 6000 square-foot farm has over 30 different varieties of vegetables. Nearby restaurants have caught on to the idea and the urban farmers have been making deliveries on their bikes - now that's local.
