The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) is a part of the United Nations that focuses on coordinating humanitarian response efforts during crises. It works to ensure that aid reaches those in need, especially in situations like natural disasters, conflicts, and pandemics. OCHA collaborates with various organizations, governments, and local communities to provide effective assistance. OCHA also plays a crucial role in advocating for the rights of affected populations and ensuring that humanitarian principles are upheld. By gathering and sharing information, OCHA helps to improve the overall response to emergencies and supports the delivery of essential services to vulnerable communities.
