Abstract

Bangladesh faces a severe socio-economic challenge from riverbank erosion, particularly along the Jamuna River’s left bank near Chouhali and Sirajganj, significantly impacting livelihoods, homes, and social structures. This study aimed to delineate the demographics of displaced populations, quantify erosion’s extent and socioeconomic effects, and analyze migration patterns. The methodology integrates field surveys with geospatial analysis to give a thorough grasp of the magnitude of riverbank erosion and its effects on nearby population. Household surveys, in-depth interviews, and field observations were used to collect primary data in Chouhali. 200 households in all, representing a range of socioeconomic groups within the community, were polled. Changes in bankline and rates of erosion during the past 3 decades were examined using Landsat imagery from Google Earth Engine (GEE) and Digital Shoreline Analysis System (DSAS). According to the analysis, settlements were displaced as a result of the erosion of about 4.873 km of land between 1990 and 2025. Home-steads, infrastructure, and agricultural fields, have been washed away during the last 35 years, forcing about 12,739 of residents to evacuate, 10% of the house-holds polled had migrated to safer zones and surrounding urban areas after experiencing partial or complete land loss. There is an increasing tendency of permanent settlement in urban areas. In order to lessen the consequences of erosion on human settlements, the study’s conclusion highlights the urgent necessity for comprehensive riverbank protection techniques and tools like GEE and DSAS play in tracking the dynamic processes of riverbank erosion and how they affect populated areas.
