United States. Central Intelligence Agency, CIA World Fact Book, 2004 — Burkina Faso (2004)
“ One of the poorest countries in the world, landlocked Burkina Faso has few natural resources, a fragile soil, and a highly unequal distribution of income. About 90% of the population is engaged in (mainly subsistence) agriculture, which is vulnerable to variations in rainfall. Cotton is the key crop. ”
