Back in 2009 we looked at Urban Rooftop Farming and its potential in Seattle: 

”  A very cool look at Urban Rooftop Farming – in this example, underutilized rooftop space becomes home to local organic farmers who then deliver the produce via bicycles to nearby restaurants. Many possibilities with this concept, especially in Seattle with the glut of industrial rooftops the city looks over to the South.”

The Wall Street Journal features the concept’s success this week in dense New York City.
