Casamance is one of the most ethnically diverse parts of Senegal. UNESCO, the United Nations Educational, Scientific and Cultural Organization, estimates that some 15 ethnic languages are in danger of disappearing in this region alone. One of these is Bainouk, which is spoken by roughly 1,700 people. At Kairaba FM, in Diouloulou, they deliver a one-hour program broadcast entirely in Bainouk.
