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 shelter 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


As our towns and cities grow at unprecedented rates setting the social, political, cultural and environmental trends of the world, sustainable urbanisation is one of the most pressing challenges facing the global community in the 21st century. In 1950, one-third of the world’s people lived in cities. Just 50 years later, this proportion has risen to one-half and will continue to grow to two-thirds, or 6 billion people, by 2050. Cities are now home to half of humankind. They are the hub for much national production and consumption – economic and social processes that generate wealth and opportunity. But they also create disease, crime, pollution and poverty. In many cities, especially in developing countries, slum dwellers number more than 50 per cent of the population and have little or no access to shelter, water, and sanitation. This is where UN-HABITAT is mandated to make a difference for the better.
