Significant barriers and constraints persist for adaptation efforts in developing countries. Access to relevant knowledge and technical resources, as well as the capacity to utilize these resources on adaptation are some of the most pressing challenges. UNEP works to address these challenges by enhancing the capacity of developing countries to make adaptation decisions that are based on best available knowledge and technical information, strengthening institutional and policy frameworks for adaptation, and supporting countries in integrating adaptation issues into national development planning and legislative processes. These activities build directly on UNEP’s scientific and assessment work.
