DECCMA: assessing the options, limits and potential for adaptation to climate change in deltas

Large tracts of land at low lying elevation make deltas vulnerable to sea-level rise and other climate changes impacts. Deltas have some of the highest population densities in the world. The adaptive strategies available to residents of deltas (such as disaster risk reduction, land use management or polders) may not be adequate to cope with pervasive, systematic, or surprise changes associated with climate change. Large movements of deltaic people are often projected under climate change. 

This project analysed the impacts of climate change and other environmental drivers across contrasting deltas in Africa and Asia. We used surveys, participatory research and economic methods to examine processes of migration and used an integrated assessment to contrast potential migration with other possible adaptation approaches.
