Urban Farming Spotlight: Cuba

Cuba Hydroponics

Make no mistake, I am absolutely thrilled that President Obama and Raul Castro are embarking on a process to normalize relations between the United States and Cuba. Sadly, the opening of many socialist states to the West has signaled the demise of alternative agricultural sciences such as agroecology. Cuba faced a crisis in the early s, following the twin challenges of a U. The immediate test was how to feed the country with an extremely limited ability to import oil and food with both dropping by 50 percent as well as an 80 percent drop in fertilizer and pesticide imports. Reorienting the Cuban agricultural landscape toward food production was no small task. In order to facilitate this process, 80 percent of the farmland that was once held by the state, including sugar cane plantations, was turned over to workers. New agroecological farming practices were introduced, and the government plunged head first into an urban agricultural program to boost food production. Remarkably, by the mids, because of soaring domestic production, Cuba had as much food as before the collapse of the Soviet Union and caloric intake had returned to normal. Unlike modern American agriculture — long characterized by its energy-intensive approach that involves mechanization, hybrid seeds, inorganic fertilizers and pesticides — Cuban scientists needed to find a way to boost production without increasing fossil-fuel consumption. They did this through the careful study of ecological interactions in farm fields that is, agroecology. By using plant associations — such as legumes to fix nitrogen for grain crops, the intensive production of compost and the use of biopesticides — Cuban scientists demonstrated that agroecology was as or more effective at increasing crop production than conventional methods. Cuban scientists also inspired academics and activists in the United States to explore similar alternatives. For example, Will Smith of Growing Power in Milwaukee has developed similar techniques to foster urban agriculture in his city. Cuba is not the first state to actively explore and support agroecology. Unfortunately, in both cases, the science of alternative agriculture came to a grinding halt as relations tightened with the West — and with the United States, in particular. American philanthropies such as the Rockefeller and Ford Foundations launched intensive agriculture programs in India during this time, and U. From that point forward, a Green Revolution strategy for increasing agricultural productivity trumped an agroecological one. China would also import hybrid-seed technology from the United States, which it emulated and eventually produced locally. As Cuba normalizes its relations with the United States, tighter connections with the U. Rather than following the path of India or China, Cuba ought to be wary of the triumphalist U. Our energy-intensive approach to food production is not only a major source of greenhouse gas emissions, but soil erosion, water waste and limited agro-biodoversity are also major issues. A more positive outcome would be an equitable exchange of ideas between the U. William G. Moseley is professor and chair of geography at Macalester College in St. Home All Sections Search.
