Cuban local

"Around 15 percent of the world's food is grown in urban areas, according to the U.S. Department of Agriculture, a figure experts expect to increase as food prices rise, urban populations grow and environmental concerns mount.

Since they sell directly to their communities, city farms don't depend on transportation and are relatively immune to the volatility of fuel prices, advantages that are only now gaining traction as "eat local" movements in rich countries.

In Cuba, urban gardens have bloomed in vacant lots, alongside parking lots, in the suburbs and even on city rooftops." (Thanks Marcy)
