Refugees International issued an excellent summary on 13 December 2011 of the ongoing food shortage and famine problem in the Horn of Africa. The main focus of the report is Somalia.
It notes that the situation grows more complicated with the onset of rains, which encourage the spread of disease in displacement camps, and fighting in southern Somalia. The most vulnerable populations are new Somali refugees in Kenya and Ethiopia, long-term refugees at Dadaab in Kenya, internally displaced Somalis in Mogadishu, and civilian populations throughout south and central Somalia.
The refugee population at Dabaab has reached 463,000, the refugees camps inside Ethiopia have 138,000 persons, IDPs in Mogadishu number at least 370,000, and the largest number of affected Somalis are in Al-Shabaab controlled territory in south and central Somalia where aid continues to be looted by Al-Shabaab and other armed actors on its way to distribution points.
