The 2011 drought in the Horn of Africa left 13.3 million people in need of humanitarian assistance. CERF funds have been used to address the crisis as rainfall levels diminished towards the end of 2010. More than US$128 million was allocated to drought-affected persons in Djibouti, Ethiopia, Kenya and Somalia in 2011. In 2012, another $20 million, followed by $21 million in 2013, was allocated to the region – mostly through the Underfunded Emergency window. Since 2011, CERF has disbursed a total of $169.8 million to the Horn of Africa.
