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


The mandate of OCHA includes coordination of humanitarian response, policy development and humanitarian advocacy. OCHA carries out its coordination function primarily through the Inter-Agency Standing Committee (IASC) chaired by the Emergency Relief Coordinator (ERC). Participants include all humanitarian partners, from United Nations agencies, funds and programmes to the Red Cross Movement and non-governmental organizations (NGOs). IASC ensures inter-agency decision-making in response to complex emergencies. These responses include needs assessments, consolidated appeals, field coordination arrangements and the development of humanitarian policies.
