When Cuba faced the shock of lost trade relations with the Soviet Bloc in the early 1990s, food production initially collapsed due to the loss of imported fertilizers, pesticides, tractors, parts, and petroleum. The situation was so bad that Cuba posted the worst growth in per capita food production in all of Latin America and the Caribbean. But the island rapidly re-oriented its agriculture to depend less on imported synthetic chemical inputs, and became a world-class case of ecological agriculture. This was such a successful turnaround that Cuba rebounded to show the best food production performance in Latin America and the Caribbean over the following period, a remarkable annual growth rate of 4.2 percent per capita from 1996 through 2005, a period in which the regional average was 0 percent.
Global forces are challenging the ability of developing countries to feed themselves. A number of countries have organized their economies around a competitive export-oriented agricultural sector, based mainly on monocultures. It may be argued that agricultural exports of crops such as soybeans from Brazil make significant contributions to the national economies by bringing in hard currency that can be used to purchase other goods from abroad. However, this type of industrial agriculture also brings a variety of economic, environmental, and social problems, including negative impacts on public health, ecosystem integrity, food quality, and in many cases disruption of traditional rural livelihoods, while accelerating indebtedness among thousands of farmers.
