São Tomé and Príncipe is a Portuguese-speaking island nation in the Gulf of Guinea, off the western equatorial coast of Central Africa. It consists of two archipelagos around the two main islands: São Tomé and Príncipe, located about 1400NaN0 apart and about 250and, respectively, off the northwestern coast of Gabon.
Since the 19th century, the economy of São Tomé and Príncipe has been based on plantation agriculture. At the time of independence, Portuguese-owned plantations occupied 90% of the cultivated area. After independence, control of these plantations passed to various state-owned agricultural enterprises. The main crop on São Tomé is cocoa, representing about 95% of agricultural exports. Other export crops include copra, palm kernels, and coffee.
