This annual report by the Central Emergency Response Fund (CERF) of the United Nations Office for the Coordination of Humanitarian Affairs (UNOCHA) highlights that climate-related emergencies top all categories of humanitarian assistance with 149 million US dollars provided in financial assistance. The report details the early response activities the fund has provided to several crises. It indicates that climate-related emergencies, including the impact of droughts, floods and storms, expose the poor and the most vulnerable to long-term health risks and disrupt livelihoods and wellbeing. The report notes that almost a quarter of CERF funds in 2011 were allocated to drought-related emergencies in eight countries and the largest humanitarian emergency was to respond to the drought and food insecurity in the Horn of Africa.
