The second United Nations Conference on Human Settlements (Habitat II, Istanbul, Turkey, 3-14 June 1996) was a key historical moment signaling a new pathway for long-term policy development. A comprehensive vision and broad policy agendas previously endorsed by the New Urban Agenda and the Global Strategy for Shelter were reaffirmed. Furthermore, chapter 7 of Agenda 21 introduced the idea of sustainable development in application to human settlements.
