The United Nations Human Settlements Programme (UN–Habitat) is the United Nations agency for human settlements and sustainable urban development. It was established in 1978 as an outcome of the First UN Conference on Human Settlements and Sustainable Urban Development (Habitat I) held in Vancouver, Canada in 1976. UN-Habitat maintains its headquarters at the United Nations Office at Nairobi, Kenya. It is mandated by the United Nations General Assembly to promote socially and environmentally sustainable towns and cities with the goal of providing adequate shelter for all. It is a member of the United Nations Development Group.The mandate of UN-Habitat derives from the Habitat Agenda, adopted by the United Nations Conference on Human Settlements (Habitat II) in Istanbul, Turkey, in 1996. The twin goals of the Habitat Agenda are adequate shelter for all and the development of sustainable human settlements in an urbanizing world.
Since October 2010 the Executive Director is Joan Clos, former mayor of Barcelona and Minister of Industry, Tourism and Trade of the Government of Spain.
The UN-Habitat mandate is also derived from General Assembly resolution 3327 (XXIX), by which the Assembly established the United Nations Habitat and Human Settlements Foundation; resolution 32/162, by which the Assembly established the United Nations Centre for Human Settlements (Habitat); and resolution 56/206, by which the Assembly transformed the Commission on Human Settlements and the United Nations Centre for Human Settlements (Habitat), including the United Nations Habitat and Human Settlements Foundation, into UN-Habitat. The mandate of UN-Habitat is further derived from other internationally agreed development goals, including those contained in the United Nations Millennium Declaration (Assembly resolution55/2), in particular the target on achieving a significant improvement in the lives of at least 100 million slum-dwellers by the year 2020; and the target on water and sanitation of the Plan of Implementation of the World Summit on Sustainable Development, which seeks to halve, by the year 2015, the proportion of people without sustainable access to safe drinking water and basic sanitation. Through Assembly resolution 65/1, Member States committed themselves to continue working towards cities without slums, beyond current targets, by reducing slum populations and improving the lives of slum-dwellers.
