Mandarmani is a popular seaside tourist destination in Coastal West Bengal, India. The geomorphologically dynamic and ecologically diverse terrain falls within an active coastal belt with strong erosion but limited accretion. It is important to monitor and predict changes in beach morphology and shoreline over a short and long timescale to identify the specific drivers of such changes and their related impacts. While manual ground surveying techniques are relatively more accurate for this purpose, Remote Sensing and GIS techniques are proven to be more applicable as they are relatively accurate, cost-effective, less time-consuming and can cover a large coastal belt. The present paper analysed the beach morphology and shoreline changes along the Digha-Mandarmani coast of West Bengal using RS & GIS as a tool and fish net model to demarcate the erosion and accretion zones, to project the future shoreline position and understand the risk of climatic hazard on the tourism establishments and their sustainability in this region in future. Such a study would help in taking informed policy choices by the planners on such growing tourism destinations developed over time, often violating the existing coastal zone regulations and thus without required environmental clearances. Should be protected with public investment to safeguard the business hub, or will be allowed to face its natural consequences?
