This guide on adaptation options is aimed at local decision-makers on the coastal regions of west Africa and takes the form of a series of fact sheets, each including methods of implementation, positive and negative case studies and estimated costs. It first reviews what is already known about climate change and coastal erosion, before describing the regions (Mauritania, Senegal, The Gambia, Guinea Bissau and Cape Verde) and their respective challenges, the importance of adaptation and the responsibilities of local decision-makers.
