From 2016-2021, the NAP-GSP provided accurate climate change adaptation support to 59 developing countries, of which 28 were LDCs . This Highlights Report provides an overview of the NAP-GSP’s expanded foundational support to enhance adaptation planning and transition to implementing National Adaptation Plans in LDCs. The report aims to cover the technical capacity development provided through regional and country-level trainings. Thanks to the NAP-GSP partners, the Programme held in-person and virtual South-South and North-South exchanges, developed online tools and training packages as well as facilitated knowledge brokering between countries to share experiences and lesson learned about their adaptation planning processes over the years.
