Biophysical and socioeconomic state and links of deltaic areas vulnerable to climate change : volta (Ghana), mahanadi (India) and ganges-brahmaputra-meghna (India and Bangladesh)

Abstract

The study examines the similarities and differences of specific deltaic areas in parallel, under the project DEltas, vulnerability and Climate Change: Migration and Adaptation (DECCMA). Results of the input-output (IO) modelling show that in the case of the Indian deltas, more than 60% of cropland and pasture land is devoted to satisfying demands from regions outside the delta; while in the case of the Bangladeshi and Ghanaian deltas, close to 70% of the harvested area is linked to internal demand. Sources of data for regionalization were country level census data, statistics and economic surveys and data on consumption, trade, agricultural production and fishing harvests.
