Organopónicos
Organopónicos or organoponics is a system of urban organic gardens in Cuba. It often consists of low-level concrete walls filled with organic matter and soil, with lines of drip irrigation laid on the surface of the growing media. Organopónicos is a labour-intensive form of local agriculture.
Organopónicos first arose as a community response to lack of food security after the collapse of the Soviet Union. It is publicly functioning in terms of ownership, access and management, but heavily subsidized and supported by the Cuban government.
