The DECCMA project analyses the impacts of climate change and other environmental drivers across contrasting deltas in Africa and Asia. Processes of migration are analysed using survey, participatory research and economic methods. Potential migration of men and women are contrasted with other adaptation approaches using a stakeholder-driven and co-produced integrated assessment approach. The project study sites are the Ganges-Brahmaputra-Meghna delta (Bangladesh and India), Mahanadi delta (India) and Volta delta (Ghana).
