OCHA meaning in Governmental ?

The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) is a United Nations (U.N.) body established in December 1991 by the General Assembly to strengthen the international response to complex emergencies and natural disasters. It is the successor to the Office of the United Nations Disaster Relief Coordinator (UNDRO).

The Department of Humanitarian Affairs (DHA) was established shortly thereafter by the Secretary-General, but in 1998 was merged into OCHA, which became the U.N.'s main focal point on major disasters. OCHA's mandate was subsequently broadened to include coordinating humanitarian response, policy development and humanitarian advocacy. Its activities include organizing and monitoring humanitarian funding, advocacy, policy-making, and information exchange to facilitate rapid-response teams for emergency relief.

OCHA is led by the Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator (USG/ERC), appointed for a five-year term. Since July 2021, the role has been filled by Martin Griffiths of the United Kingdom.

OCHA organized the 2016 World Humanitarian Summit in Istanbul, Turkey. It is a sitting observer in the United Nations Development Group.
