Recognition of the critical role of financing for adaptation and resilience as an important enabler for climate risk management has strengthened . Yet, since the Intergovernmental Panel on Climate Change  5th Assessment Report , the gap between the estimated costs of adaptation and the documented  finance allocated to adaptation has widened . Estimated global and regional costs of adaptation vary widely due to differences in assumptions, methods and data; the majority of more recent estimates are higher than the figures presented in AR5 . A high proportion of developing country NDC adaptation contributions are conditional on external financial support, emphasising the crucial role of international finance to achieving adaptation efforts commensurate with climate risks . Developed country climate finance leveraged for developing countries for mitigation and adaptation has fallen short of the 100 USD billion yr-1 Copenhagen
