Is This Our Best Food Self-Sufficiency Resource?

For more than three decades, I’ve been suggesting that we need to see flat roofs as resources: they can provide space not just for solar energy, but also for gardens.

And growing up in New York City, where far too many people think that food comes out of cans or mysteriously arrives in the supermarket, this is especially true. New York has an enormous supply of flat roofs, many of which have terrific sun exposure.

So it gladdens my heart to see a project like this: utilizing flat roof space for year-round greenhouses in a long-depressed South Bronx neighborhood. On the roof of a public housing project designed to be green, in fact. My Western Massachusetts neighbor Joe Swartz (@SwartzFarm on Twitter), who is involved with this project, shared the first picture on a list we both participate on.

(The first link has an excellent picture. The second link has a crummy picture but a short informative article about the whole project.)

This is by no means the only example. It’s simpler to build without greenhouses, of course, if you don’t mind closing down for the winter. Here’s a 6,000 square-foot no-greenhouse rooftop commercial organic farm in northern Brooklyn, on a warehouse right across the river from Manhattan.
