A new 90,000-square-foot indoor farm called FarmedHere has recently opened in Chicago and is expected to produce 1 million pounds a year of organic greens like basil, lettuce, mint, and spinach. It is also expected that it will provide hundreds of local jobs. 

This very useful paper provides a much needed analysis of GHG emissions resulting from community urban food growing.  The study is located in the London Borough of Sutton ( a suburban part of london) and the area of production covers just under 3 hectares.  The study concludes that urban food prodution can deliver useful reductions in GHG emissions as compared with supermarket equivalents, provided that care is taken to produce the crops where there is the greatest environmental comparative advantage.

This report shows, through analysis and a wide variety of case studies, that urban agriculture can, in a very practical way, yield a range of benefits.

This report builds upon the Growing food in cities report. Whereas the emphasis of Growing food in cities was very much on the potential benefits of urban agriculture, this report focuses on what the actual benefits have been, and on the feasibility of developing food growing activities further, given London's specific social, economic and environmental context.
