Climate-smart villages are evolving in five West African countries from Senegal to Niger thanks to integrated participatory action research aimed at protecting food security. Climate change creates new challenges for food security in the region. To overcome these threats, the CGIAR research program on Climate Change, Agriculture and Food Security (CCAFS) developed among other tools and approaches, the Climate Smart Village (CSV) as a model for local action research to achieve food security, enhance livelihood, and improve environmental management, i.e., Climate-Smart Agriculture (CSA).
