This paper focuses on the trends in climate change in the WAEMU, assesses the criticality of climate change for the region, and reviews the related policy and financing options going forward. Climate change has been increasingly affecting the lives and livelihoods in the WAEMU. Temperatures have risen significantly, and climate-related disasters have hit the region more frequently in recent decades. Climate change can exacerbate the current challenges and hinder long-term economic prospects by threatening economic growth, food security, fiscal and external sustainability, and social outcomes in the region. Macroeconomic policies, structural reforms and cooperation among different parties remain critical alongside regional efforts, in particular to have access to necessary financing and bolster adaptation efforts.
