Agriculture remains the backbone of Cameroon's economy, employing 70 percent of its workforce, while providing 42 percent of its GDP and 30 percent of its export revenue. Blessed with fertile land and regularly abundant rainfall in most regions, Cameroon produces a variety of agricultural commodities both for export and for domestic consumption. Coffee and cocoa are grown in central and southern regions, bananas in southwestern areas, and cotton in several northern provinces. In addition to export commodities, Cameroonian farmers produce numerous subsistence crops for family consumption. Principal food crops include millet, sorghum, peanuts, plantains, sweet potatoes, and manioc. Animal husbandry is practiced throughout the country and is particularly important in northern provinces.
