Famine is a significant problem for many developing countries despite a global food surplus. Famine results from a shortage or inability to obtain food, often due to drought causing low food production. It occurs mainly in rural areas where farming and livestock are the primary means of livelihood. Nearly 30 million Africans could face famine in the coming months, with the horn of Africa, southern Africa, and the Sahel region of West Africa most at risk. Causes of famine in Africa include drought, lack of self-sufficiency requiring imports, armed conflict, environmental degradation, and climate change.
