In 1990s, sugar was still the Belizean economy's single largest export earner. Sugar production involved a unique hybrid of agricultural and industrial activity. Sugarcane cultivation, on one hand, and the mechanicalchemical transformation of cane into sugar, on the other hand, made for this speciality. Both processes needed to be coordinated because of the perishability of the crop.
Citrus production, mainly oranges and grapefruit, occurs predominantly in Belize's Stann Creek District. The citrus trade began in the 1920s, but became remarkable only in the 1980s, when Belizean-produced citrus concentrate became exempt from United States tariff duties under the terms of the CBI. Exports of fresh citrus fruit to the United States were limited because of infestation of the Mediterranean fruit fly. Citrus, much like sugar, underwent sharp price and production fluctuations, although overall export receipts from citrus concentrate markedly increased during the 1980s because of high prices.
Crops other than sugar, citrus, and bananas played a very minor role in the Belizean economy in the early 1990s. Cultivation of nonorthodox export crops were promoted by the CBI as a way of lessening dependence on sugar and banana exports. Trade incentives were offered for nonorthodox products, such as tropical fruits or winter fruits and vegetables. This strategy was only moderately successful.
