Research project: Deltas, Vulnerability & Climate Change: Migration & Adaptation - Dormant

Currently Active: 
No

Deltas are important for food security and also a major focus for development as many of the people living there are poor and reliant on subsistence livelihoods. Temporary and permanent migration is already a widespread phenomenon in deltas, so the aim is to provide better evidence to inform policy makers about the possible futures of delta. The project study sites are the Ganges-Brahmaputra-Meghna delta (Bangladesh and India), Mahanadi delta (India) and Volta delta (Ghana).

The focus of DECCMA is on climate change and sea-level rise; however, many other drivers such as catchment management (e.g. sediment starvation due to dams), economic changes or governance can affect migration and other in-situ changes that are also considered. DECCMA aims to assess the adaptation options in the study areas and to identify the unsustainable coping and maladaptation strategies.

Successful adaptation will suppress climate-induced migration, but migration may still occur for other reasons. Finally, DECCMA recognises that migration can have both negative and positive impacts on social systems. It aims to assess the motives of migration and under what conditions the migration might be considered successful. Thus DECCMA aims to provide insight into the larger scale processes, AND unpack the local community processes and the intra-household dynamics, including gender roles and relations.

To achieve such an ambitious goal, several sectoral analysis are being conducted (biophysical, demography and migration and economic assessments), governance and stakeholder assessments and adaptation is also being assessed. To draw these diverse components together an integrated assessment framework and an integrated model is being developed, including relevant scenarios to consider future changes. The results are designed to be policy relevant and transferable to other deltas.
