UN-Habitat works in over 90 countries to promote transformative change in cities and human settlements through knowledge, policy advice, technical assistance and collaborative action. UN-Habitat’s new strategic plan 2020-2023 adopts a more strategic and integrated approach to solving the challenges and opportunities of twenty-first century cities and other human settlements. The UIA works with UN-Habitat on numerous issues, most recently the UIA 2030 Award to promote the work of architects contributing to the UN 2030 Agenda for Sustainable Development.
