Since the 1990s food crisis, Havana has built a citywide network of organopónico urban farms and co-ops covering ~8% of city land; by 2013 they and allied gardens supplied roughly 50-60% of the city's fresh produce using low-pesticide, organic methods.
Since the 1991 collapse of Soviet subsidies cut off imported farming inputs (Cuba's "Período Especial"), the government redirected vacant urban land to food production, creating organopónico raised-bed market gardens run mostly by worker cooperatives on rent-free state land.
Growers use crop rotation, compost and biological pest control with minimal synthetic pesticide; cooperatives exceeding state quotas can sell surplus at farmers' markets, with top earners making up to double the national wage.
By 2013 food gardens covered about 8% of Havana's city land and local farms supplied roughly 100,000 tonnes of fruit and vegetables a year — an estimated 50-60% of the city's fresh produce — with 97 high-yield cooperatives operating that year; nationally the programme counted over 4,000 urban farms producing about 1.2 million tonnes of vegetables and herbs.
The model is not self-sufficient — Cuba still imports significant meat and wheat — and independent reporting cautions that fuel and input shortages during Cuba's ongoing economic crisis strain the programme, with cheaper imports a potential future threat to local growers.
