Problems and issues

water In the tidal delta, dry-season salinity intrusion pushes saline water inland through rivers and shrimp ghers, stressing freshwater supply. So what: Salinity narrows safe drinking-water sources and constrains freshwater cropping. Source: Department of Public Health Engineering
climate disaster Low coastal elevation in the delta exposes Chitalmari to cyclone-driven tidal surge and monsoon waterlogging. So what: Surge and waterlogging 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 flush silt and reduce salinity intrusion. Responsible: Bangladesh Water Development Board · policy proposal
Scale rainwater harvesting and managed aquifer recharge to secure dry-season drinking water in saline-affected unions. Responsible: Department of Public Health Engineering · policy proposal
