Check out foodurbanism.com (done by VWA in Switzerland) which is a good Atlas of info. I think Zurich Urban Farmers in Zurich is on the right path of figuring out how to make it profitable. In Canada, HBLanarc wrote a book about their work which is more about planning and design.
All good stuff! Good luck.
Thanks! Great advice!
