Mihag Gedi Farah, a malnourished seven-month-old child weighing only 7.5 pound (3.4kg), is held by his mother in a field hospital of the International Rescue Committee, IRC, in the town of Dadaab, Kenya, on July 26, 2011. The U.N. will airlift emergency rations this week to parts of drought-ravaged Somalia that militants banned it from more than two years ago, in a crisis intervention to keep hungry refugees from dying along what an official calls the "roads of death." Tens of thousands already have trekked to neighboring Kenya and Ethiopia, hoping to get aid in refugee camps. #

A woman waits for food rations at a feeding center in Lolkuta, near Wajir, on July 21, 2011. The UN's World Programme Programme was preparing on July 26, 2011 to airlift food aid into the Somali capital Mogadishu, but efforts were hampered by last minute paperwork in Kenya. An estimated 3.7 million people in Somalia -- around a third of the population -- are on the brink of starvation and millions more in Djibouti, Ethiopia, Kenya and Uganda have been struck by the worst drought in the region in 60 years. #

An aid worker using an iPad photographs the rotting carcass of a cow in Wajir, near the Kenya-Somalia border, on July 23, 2011. Since drought gripped the Horn of Africa, and especially since famine was declared in parts of Somalia, the international aid industry has swept in and out of refugee camps and remote hamlets in branded planes and snaking lines of white 4x4s. This humanitarian, diplomatic and media circus is necessary every time people go hungry in Africa, analysts say, because governments - both African and foreign - rarely respond early enough to looming catastrophes. Combine that with an often simplistic explanation of the causes of famine, and a growing band of aid critics say parts of Africa are doomed to a never-ending cycle of ignored early warnings, media appeals and emergency U.N. feeding - rather than a transition to lasting self-sufficiency. Picture taken July 23, 2011. #
