The Comoros, officially the Union of the Comoros, is a sovereign archipelago island nation in the Indian Ocean, located at the northern end of the Mozambique Channel off the eastern coast of Africa, between northeastern Mozambique and northwestern Madagascar. Agriculture, including fishing, hunting, and forestry, is the leading sector of the economy. It contributes 40% to GDP, employs 80% of the labor force, and provides most of the exports. The country is not self-sufficient in food production; rice, the main staple, accounts for the bulk of imports. The Comoros is one of the world's poorest countries. Economic growth and poverty reduction are major priorities for the government.
