Lynsey Addario/VII
Somali refugees arrive in Ifo 2 camp after being moved by officials from the outskirts of Dagahaley camp. Dadaab, with roughly 400,000 refugees, Dadaab is the largest refugee camp in the world. The camp is grossly over capacity, and the refugees experience an ever-shrinking access to essential services such as water, sanitation, food and shelter, also because they have been sharing their rations with the new arrivals. At the current pace of arrival MSF estimates that the camp's population will total 500'000 before the end of 2011, and living conditions are only expected to deteriorate further.
