OCHA coordinates humanitarian action to ensure crisis-affected people receive the assistance and protection they need.It works to overcome obstacles that impede humanitarian assistance from reaching people affected by crises, and it provides leadership in mobilizing assistance and resources on behalf of the humanitarian system.OCHA’s non-programmatic coordination role enables it to fulfil its unique function as an honest broker in the humanitarian sector, and to promote trust among all humanitarian actors.
This new function would combine into a single United Nations focal point the functions carried out by the Secretary-General's representatives for major and complex emergencies, as well as the United Nations' natural disaster functions carried out by the United Nations Disaster Relief Organization.
Soon after the resolution was adopted, the Secretary-General established the Department of Humanitarian Affairs (DHA).
This was also formally recognized in the Secretary-General’s 1997 reform agenda, which assigned the ERC with responsibility for the overall coordination of assistance to IDPs.
The GA expressed support for the reform agenda, and in subsequent resolutions it has emphasized ‘the central role of the ERC’ for coordinating the protection of and assistance to IDPs.
GA resolution 46/182 assigns a clear leadership and coordination role to the ERC for international humanitarian assistance to respond to the needs of affected people.
This mandate extends to affected people in internally displaced persons (IDPs) situations and was reinforced by related GA resolutions (including GA resolution 70/165).In 1998, as part of the Secretary-General's programme of reform, DHA was reorganized into the Office for the Coordination of Humanitarian Affairs (OCHA).Its mandate was expanded to include the coordination of humanitarian response, policy development and humanitarian advocacy.OCHA’s role is to augment national and local coordination capacities, and to promote coordination structures that are complementary to established national mechanisms and capacities.Accountability to affected people OCHA’s primary partners include affected people, Member States, IASC organizations, and national and international NGOs.OCHA carries out its coordination function primarily through the IASC, which is chaired by the ERC.
