The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) is responsible for coordinating humanitarian responses to crises and disasters around the world. OCHA was established in 1991 and is headquartered in New York City, with offices in Geneva and other locations. The organization works to ensure effective and timely responses to humanitarian emergencies, working closely with governments, non-governmental organizations (NGOs), and other stakeholders to coordinate relief efforts and mobilize resources. OCHA also serves as an information hub, collecting and disseminating information about crises and providing analysis to support decision-making. Through its work, OCHA plays a vital role in helping to alleviate the suffering of those affected by crises, and in promoting more effective and coordinated humanitarian responses worldwide.
