The United Nations Human Settlements Programme, UN-Habitat, is the United Nations agency for human settlements. It is mandated by the UN General Assembly to promote socially and environmentally sustainable towns and cities with the goal of providing adequate selter for all. The main documents outlining the mandate of the organization are the Vancouver Declaration on Human Settlements, Habitat Agenda, Istanbul Declaration on Human Settlements, the Declaration on Cities and Other Human Settlements in the New Millennium and Resolution 56/206.
In addition to its advocacy and monitoring functions, UN-Habitat plays an important role in providing technical assistance to countries and cities in the areas of urban governance, housing, environmental management, disaster mitigation, post-conflict rehabilitation, urban safety, water management and urban poverty reduction. UN-Habitat as part of its global mandate has an established Disaster Management Unit at its headquarters in Nairobi. This unit is resourced with specific expertise on vulnerability reduction as well as post-disaster reconstruction and recovery.
