Figure 2: Urban agriculture in Cuba
Since 1987 Cuba has focused on urban and suburban agriculture to counter its crisis of lack of imports as well as malnutrition and iron deficiency in the population. More than 54,000 hectares are currently dedicated for urban agriculture, including vegetables, fruits, apiculture, and livestock. Havana alone supports one of the most extensive urban agriculture networks in the world: 4 million tons of vegetables are grown each year in more than 200 urban organic farms, known as organiponicos. Urban agriculture produces 90 percent of Havana's fruits and vegetables while reducing the city's carbon footprint by trading the produce in local markets.

Figure 3: Lufa Farms, Montreal
Rooftop gardening is catching on all over the world. In Montreal, Canada, where local fruits and vegetables can be hard to find except during the brief summer growing season, a 31,000-square-foot greenhouse known as Lufa Farm sits atop an office building. It grows more than 25 varieties of vegetables year-round, and it does so without using any artificial pesticides, fungicides, or herbicides. The use of controlled-environment agriculture enables the operation to yield as much as a conventional farm 10 times its size.
