The producers of the main export crops are organized into associations, and there are also organizations of small farmers. The Jamaica Agricultural Society, founded in 1895, is concerned with agricultural and rural development and works closely with the government. The cooperative movement has grown rapidly since World War II. All cooperatives must register with the government and are subject to supervision. Savings and credit groups are the most numerous, followed by marketing organizations. Consumer cooperatives have had little success. Outside the agricultural sector, the chambers of commerce have long been the most important business groups.
Societies and associations for the study and advancement of various branches of science and medicine have developed. These include the Medical Association of Jamaica and the Science Research Council.
