The Ganges–Brahmaputra–Meghna delta system: biophysical models to support analysis of ecosystem services and poverty alleviation

Abstract

Deltas have been recognised as some of the most vulnerable coastal environments for the last 30 or more years, following initial concerns about climate induced sea-level rise. However, this is just one driver, and it is increasingly recognised that deltas are vulnerable to multiple drivers of change at multiple scales. These include changing catchment management upstream of the deltas, subsidence within the delta, land cover change within the delta and marine processes such as ocean circulation, cyclones and storms.
