Assessing the correlation between sea level rise, temperature, and erosion-accretion along the coastline of Bangladesh
Abstract The coastal region of Bangladesh along the Bay of Bengal is highly vulnerable to climate change impacts, including land erosion, sea level rise, and extreme weather events, while also offering economic opportunities in fisheries, tourism, and port facilities.

| Summary: | Abstract The coastal region of Bangladesh along the Bay of Bengal is highly vulnerable to climate change impacts, including land erosion, sea level rise, and extreme weather events, while also offering economic opportunities in fisheries, tourism, and port facilities. This comprehensive study examines the correlation between temperature, sea level rise, and land area changes over the past 30 years in 10 coastal districts across three zones: the Ganges Tidal Plain, Meghna Deltaic Plain, and Chittagong Coastal Plain. Historical temperature data from 34 to 63 years were analyzed using linear regression, revealing an increasing trend. Sea level rise was assessed using 20–45 years of data from seven tidal stations, showing a consistent upward trend. Landsat images were used to digitize shorelines and evaluate erosion and accretion dynamics, indicating significant land loss in all coastal districts. The western and central coastal zones demonstrated the most notable impact of climate change. These findings provide valuable insights for developing future adaptive strategies, infrastructure planning, disaster preparedness, and socioeconomic resilience in the face of ongoing climate change challenges in coastal Bangladesh. The study's results underscore the urgent need for targeted interventions to mitigate vulnerabilities and optimize opportunities in this critical region. Clinical trial number Not applicable. |
