Research project

Deltaic Environments, Vulnerability and Climate Change: Migration as Adaptation (DECCMA)

Project overview

DECCMA is a 4 year, IDRC-funded, CAD$13.5million programme of applied research on the adaptation options, limits and potential in deltaic environments to current weather variability and extremes, as well as climate change. The project ran from February 2014 to September 2018. Research focussed on four deltas – the Ganges-Brahmaputra-Meghna (Bangladesh and India); the Nile (Egypt); the Volta (Ghana); and the Mahanadi (India). Large tracts of land at low elevation make deltas vulnerable to sea-level rise, but they also experience climate impacts such as droughts and fluvial flooding. Deltas have some of the highest population densities in the world with 500 million, often poor, residents. Key outputs all free to download:


Lead researcher

Professor Robert Nicholls

Research interests

  • long-term coastal engineering and management
  • the issues of coastal impacts and adaptation to climate change, with an emphasis on sea-level rise
  • the assessment of the future of deltaic areas, which are the most threatened coastal setting in the coming century
Other researchers

Professor Steve Darby

Associate Dean Research

Research interests

  • River and coastal flooding - relationships between geomorphology and flooding in rivers and deltas
  • Biogeomorphology - interactions between river processes and life
  • River bank erosion processes
