The United Nations Development Programme (UNDP) Funding Windows are flexible pooled funding mechanisms designed to support the implementation of the 2030 Agenda for Sustainable Development. They provide catalytic funding to UNDP’s efforts to reduce poverty, and promote resilient, sustainable and risk-informed development. The resources are directed towards countries most in need such as least developed countries (LDCs), small island developing states (SIDS), and countries in situations of crisis and post-crisis as well as those vulnerable to being left behind in the development process. Flexible funding allows UNDP to respond to the varied needs of countries at different points on the development spectrum, tailoring its integrated and cross-sectoral approach to address the unique challenges each country faces.
