Gaibandha District
Local Gov
A char-laden district on the lower reaches of the Teesta, Brahmaputra-Jamuna and Ghaghot rivers in northern Bangladesh, where shifting sandy chars and monsoon flooding shape a poor, agriculture-dependent economy. Its plains are among the poorest in the country, and seasonal river dynamics drive recurrent displacement and erosion of farmland.

Problems and issues
- poverty Persistent deep poverty: the district sits in the poorest fifth of Bangladesh by mean Relative Wealth Index (rank 19 of 64), reflecting the concentrated deprivation of its char and floodplain populations. So what: A large share of households lacks the asset buffer to absorb a single flood or crop loss, so shocks translate directly into hunger and distress migration.

- climate disaster High monsoon rainfall (1,986 mm/yr) combined with multiple braided rivers produces annual flooding and char inundation, while the same rivers cut away inhabited and cultivated chars. So what: Recurrent flooding and bank erosion destroy homesteads and standing crops, keeping char families in a cycle of rebuilding and landlessness.

- water River-bank erosion along the Teesta-Brahmaputra-Ghaghot system continuously consumes farmland and shifts the location of habitable chars. So what: Erosion permanently strips families of their main productive asset (land), creating a steady flow of landless climate migrants the local economy cannot absorb.

- agriculture Warming of about 0.52 C in district air temperature adds heat stress on top of an economy still anchored in flood-exposed char and floodplain cropping. So what: Rising temperatures squeeze yields and farm-labour productivity in a district with few non-farm fallbacks, deepening rural income insecurity.

- urbanization Built-up surface has grown about 83% since 2000 to 32.5 km2, concentrating settlement and services in flood-prone towns without commensurate drainage or planning. So what: Unplanned expansion onto floodplains raises exposure of new infrastructure to the very inundation that already defines the district.

Probable solutions
- Char-focused livelihood and resilience support combining elevated homestead plinths, flood-tolerant cropping and asset transfers for erosion-displaced households. Responsible: Department of Disaster Management / Local Government Engineering Department (LGED) · policy proposal
- Targeted river-bank protection and dredging on the most active erosion reaches of the Teesta and Brahmaputra-Jamuna to stabilise inhabited chars and farmland. Responsible: Bangladesh Water Development Board · policy proposal
- Extension of heat- and submergence-tolerant rice varieties and char-suited cropping calendars to protect yields under rising temperatures. Responsible: Department of Agricultural Extension · policy proposal
- Flood-sensitive municipal land-use planning and drainage upgrades to keep built-up growth off the most flood-prone floodplain. Responsible: Local Government Engineering Department (LGED) · policy proposal
