This case study analyses the results, lessons learned and recommendations emerging from the application of the Climate Vulnerability and Capacity Assessment (CVCA) methodology. The assessment was carried out within CARE’s framework for Community-based Adaptation (CBA) in the context of the Global Water Initiative (GWI) in East Africa, funded by the Howard G. Buffett Foundation.This programme is being implemented in four countries in the East Africa Region (Ethiopia, Kenya, Uganda and Tanzania) by a partnership that includes CARE, Action Against Hunger, Catholic Relief Services (CRS), International Union for the Conservation of Nature (IUCN) and Oxfam America. The following sections present an overview of the programme, the areas of intervention by country, the results of the analysis itself, and lastly, the main lessons learned and recommendations that arose from the application of the different tools contained in the CVCA Handbook in the four countries.
