UN Sister Organizations
As humanitarian crises have become more and more complex, UNHCR has expanded both the number and type of organizations it works with. The refugee agency has long worked closely with sister UN agencies, whose work complements or converges with UNHCR's.
Most important among these are the World Food Programme (WFP), the UN Children's Fund (UNICEF), the World Health Organization (WHO), the UN Development Programme (UNDP), the Office for the Coordination of Humanitarian Affairs (OCHA), the UN High Commissioner for Human Rights (OHCHR) and the Joint UN Programme on HIV/AIDS (UNAIDS).
UNHCR is also committed to working closer with other agencies through the "Delivering as One" initiative, which aims at improving cooperative UN action in the areas of areas of development, humanitarian assistance and the environment. The refugee agency has also embraced the so-called "cluster approach" to IDP (internally displaced people) emergencies, whereby different agencies take the lead in their area of expertise while working together to help those in need. UNHCR takes the lead for protection and shelter needs, and camp coordination and management.
