Problems and issues

water Dry-season salinity intrusion pushes saline water inland through delta rivers and ghers, stressing freshwater sources. So what: Salinity constrains safe drinking water and freshwater cropping. Source: Department of Public Health Engineering
climate disaster Low coastal elevation exposes the upazila to cyclone surge and monsoon waterlogging. So what: Surge and standing water damage crops and homes. Source: Department of Disaster Management

Probable solutions

Rehabilitate coastal polder embankments and sluice gates and expand managed tidal river management to reduce salinity intrusion. Responsible: Bangladesh Water Development Board · policy proposal
Scale rainwater harvesting and managed aquifer recharge to secure dry-season drinking water. Responsible: Department of Public Health Engineering · policy proposal
