According to United Nations Environment Programme (UNEP), the adaptation gap can be defined generically as the difference between the level of adaptation actually implemented and a societally set target or goal, reflecting nationally determined needs related to climate change impacts, as well as resource limitations and competing priorities. The Adaptation Gap Report (AGR) series produced by UNEP since 2014 provides an annual science-based assessment of the global progress on adaptation planning, financing, and implementation, with the aim to inform the climate negotiations among UN Member States.
