Abstract: Ghoramara Island, located off the coast of West Bengal, India. This is among the most vulnerable regions in the world facing the impact of climate change. The island has experienced significant environmental changes, including rising sea levels, erosion, and cyclones, which have drastically reduced its land area from around 9.09 square kilometres in 1970 to just 2.88 square kilometres today. A major portion of the island is now submerged and the remaining land is at high risk. The present study aims to develop a mathematical model to analyze the island's areal changes from 1970 to 2020. Utilizing the non-linear least squares method, residual analysis, and regression analysis, we characterize the island's changing landscape. The proposed model effectively captures the trend of area reduction and provides a mathematical explanation for these changes. Its novelty and accuracy are confirmed through statistical measures such as R-squared and adjusted R-squared, both indicating strong results. This model can be used to predict future changes on Ghoramara Island.
