Investigation of Riverbank Erosion Towards Migration Pattern in Kazipur Upazila, Sirajgonj Area

Abstract

Worldwide, communities who live near riverbanks face a serious threat from riverbank erosion, which can cause migration and displacement patterns that have a substantial influence on both environmental sustainability and socioeconomic dynamics. In the Kazipur Upazila of Sirajganj District, Bangladesh, this thesis focuses on the Jamuna River and examines the connection between riverbank degradation and migration trends. Over time, significant erosion has occurred in the Jamuna River, a significant tributary of the Brahmaputra River, causing many homes to be uprooted and livelihoods to be disrupted. In order to determine the amount and geographical distribution of riverbank erosion along the Jamuna River, this study uses a mixed-methods approach that includes remote sensing analysis, geographic information system (GIS) mapping, and qualitative interviews. Qualitative interviews shed light on the socioeconomic effects of migration and displacement brought on by erosion, while remote sensing data and GIS methods are utilized to examine historical changes in riverbank morphology and land cover. The findings reveal a complex relationship between riverbank erosion and migration patterns in the study area. Analysis of remote sensing data indicates significant erosion along the Jamuna River, leading to the loss of agricultural land, homesteads, and infrastructure. Qualitative interviews with affected communities shed light on the socio-economic consequences of displacement, including loss of livelihoods, increased vulnerability to poverty, and challenges in accessing essential services. Furthermore, this study examines the coping strategies adopted by affected communities in response to riverbank erosion, such as temporary resettlement, livelihood diversification, and reliance on social networks. The research also explores the role of government policies and interventions in addressing the challenges posed by riverbank erosion and supporting affected populations. This thesis advances knowledge of the socioeconomic effects of environmental change in riverine areas by clarifying the relationship between riverbank erosion and migration dynamics. In order to lessen the effects of riverbank erosion and promote sustainable development in susceptible areas like Kazipur Upazila, Sirajganj, the findings have implications for disaster risk reduction, policy creation, and community resilience-building initiatives.
