Arakan receives much rain, so rice is the main crop, occupying around 85% of the total agricultural land. Coconut and nipa palm plantations are also important. Fishing is a major industry, with most of the catch used to feed the populace, but some is also exported (mostly to neighboring nations). Small amounts of inferior-grade crude oil are produced from primitive, shallow, hand-dug wells, but there is yet unexplored potential for petroleum and natural gas production. The Arakan government has recently constructed an official oil well after a mineral survey pinpointed a source of higher-grade oil.
