Problems and issues

1. climate disaster Set on the tidal Sugandha, the sadar faces monsoon flooding, tidal surge and waterlogging of its dense canal-and-orchard landscape. So what: Recurrent flooding and surge disrupt the town and surrounding cultivation. Source: Department of Disaster Management
2. urbanization As the district's built-up core, settlement is expanding over low, flood-prone ground from a small urban base. So what: Growth onto the lowest ground heightens exposure to flooding. Source: Local Government Engineering Department
3. water Communities cluster along tidal channels with little permanent surface water, exposed to siltation and salinity creep from downstream. So what: Tidal channels threaten safe water supply and raise contamination risk. Source: Department of Public Health Engineering

Probable solutions

• Re-excavate silted tidal rivers and canals and upgrade sluice and drainage control to reduce monsoon flooding and waterlogging. Responsible: Bangladesh Water Development Board · Bangladesh Water Development Board
• Adopt flood-risk-informed land-use planning and improved municipal drainage to steer built-up growth away from the lowest ground. Responsible: Local Government Engineering Department · Local Government Engineering Department
