Chad

A dead donkey lies partially covered by the wind-swept sand in an area of desert where villagers take dead animals to avoid the smell and potential for disease affecting them, near the village of Dala in the Sahel belt of Chad, Friday, April 20, 2012. UNICEF estimates that 127,000 children under five in Chad's Sahel belt will require lifesaving treatment for severe acute malnutrition this year, with an estimated 1 million expected throughout the wider Sahel region of West and Central Africa in the countries of Niger, Nigeria, Mali, Chad, Burkina Faso, Cameroon, Senegal and Mauritania. The organization says the current food and nutrition crisis stems from scarce rainfalls in 2011, which caused poor harvests and livestock production, though the situation in Chad has also been exacerbated by an influx of Chadians returning from Libya as a result of the conflict there.
