A woman prepares her shawl as her baby lies on the ground, after arriving by donkey to have the baby examined for signs of malnutrition at a walk-in feeding center in Dibinindji, a desert village in the Sahel belt of Chad, Wednesday, April 18, 2012. UNICEF estimates that 127,000 children under 5 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.
