United Nations Office for the Coordination of Humanitarian Affairs (OCHA)

United Nations Office for the Coordination of Humanitarian Affairs (OCHA) is the part of the United Nations Secretariat responsible for bringing together humanitarian actors to ensure a coherent response to emergencies. OCHA also ensures there is a framework within which each actor can contribute to the overall response effort. It also establishes the role of the Emergency Relief Coordinator (ERC), who works with the Secretary-General and the Inter-Agency Standing Committee (IASC) in leading, coordinating and facilitating humanitarian assistance.
