The joint UNDP-UN Environment National Adaptation Plan Global Support Programme (NAP-GSP), funded by the Global Environment Facility (GEF), has assisted over 60 least developed and developing countries in identifying technical, institutional and financial needs to integrate climate change adaptation into medium and long-term national planning and financing. The programme has operationally closed in December 2021, but the website portal remains a knowledge hub of training materials, knowledge products and country experiences documented over the programme’s lifespan.
