Migration to cities, when effectively managed, has proven to contribute positively to the socio-economic dynamism and sustainable development of cities. Migration policies are often developed at national level but implemented locally. By adopting the 2030 Agenda for Sustainable Development, the New Urban Agenda and recent Global Compacts on Migration and for Refugees, UN Member States have acknowledged the role of local authorities in ensuring inclusivity in line with the UN principle of leaving no-one behind.
UN-Habitat supports cities facing challenges due to different types of migration flows, including rural-urban migration; voluntary migration and forced displacement; migration due to conflict, natural hazards and climate change, or due to social and economic reasons. People move to cities, within their countries, within their region and across international boundaries.
UN-Habitat's new Strategic Plan 2020-2023 (in its Domaine of Change 4) focuses on inclusive and resilient cities, promoting social cohesion, underlining the positive impact of migrants to cities. UN-Habitat aims at for reducing inequalities and advancing sustainable urbanization for all inhabitats of a city.
