The Ganges Basin Development Challenge (BDC) research program will focus on brackish-water coastal zones in the Ganges Basin, where agricultural lands have a maximum salinity greater than 5 ppt (parts per thousand) in the dry season (salinity is lower in the wet season). The BDC vision of success requires innovations in water governance, improved availability of dry-season water, improved practices for managing salt-affected lands, and intensification and diversification of farm systems.
Inundation and severe flooding in the coastal areas is a frequent occurrence in Bangladesh. This leads to loss of life and property as well as severe impacts on livelihoods. The government of Bangladesh has been investing steadily in coastal zone management through construction and rehabilitation of polders. This project is about water governance and community based management of polders in coastal zones in Bangladesh. The challenges facing the polder communities are complex and similar to those faced by many communities in which water is used for multiple purposes.
This project will address the important external drivers that influence water resources of the coastal zone and to assess the anticipated changes in flooding, drainage congestions, salinity intrusion, water availability, sedimentation and risk of inundation of cyclone induced storm surge as a consequence of these drivers. The water resources in the coastal zone of the Ganges basin are vital for crop production, ecosystem sustenance and livelihoods.
Flood-prone ecosystems in South and Southeast Asia are traditionally farmed with deepwater rice followed by post-flood rice culture during the dry season. During the
flood season, the same land is inundated, creating an open-access water body subject to multiple uses by multiple users. Fish production in these areas is based on
