Displaced by the Surge: How Riverbank Erosion is Swallowing Coastal Communities

Along the vast, shifting riverbanks of the coastal delta, thousands of families wake up every morning to a coastline that is shrinking beneath their feet. Over the past decade, severe monsoon surges and accelerated riverbank erosion have erased entire villages from the map, displacing over 150,000 residents into informal urban slums.

Our six-month investigation across seven coastal districts reveals a systemic failure in embankment maintenance, budget embezzlement by local contractors, and a severe lack of long-term resettlement policies. Engineers from the Water Development Board acknowledge that over 60% of existing flood control dikes are structurally compromised.

“We lost three acres of paddy land in a single night. Now we live on embankment slopes with nowhere else to go,” says Rahima Begum, a 52-year-old mother of four.

Satellite imagery analyzed for this report confirms that more than 4,200 hectares of arable land have been lost to the river over the past five years alone. With sea levels projected to rise further, experts warn that without immediate policy intervention and transparent embankment engineering, millions more risk becoming permanent climate displaced citizens.
