Children await treatment in a hospital in the central Angolan city of Huambo September 12, 2005. The United Nations says half of Angola's children are malnourished and in some areas more than 50 percent have been permently stunted due to lack of food. Food and agricultural production is recovering from the effects of a 27 year civil war but aid workers say lack of good roads or railways means there is little incentive for subsistence farmers to shift into cash crops they will be unable to get to market.
