Socio-economic characteristics

, the resident population in the reserve was 6.737 inhabitants, all of whom live in the transition zone as all the islets are uninhabited. The economic activities in the biosphere reserve are essentially fishing and agriculture (especially cocoa, coffee and copra) besides a small tourist development, mainly composed of some tourism in the capital of Santo Antonio and an island resort in the area of Bom Bom. Agriculture and fisheries are mainly subsistence activities, particularly for consumption and trade surpluses in the local market. Agricultural and fish products are mainly consumed in their primary form, but there are some processed products such as dried fish, fried bananas, the “cacharamba” (local sugar cane rum) and palm wine.
