Coastal areas are regions that have immense potential for environmental services and resources related to social, economic, and cultural activities. The coastal region of Kachchh, Gujarat, India, is facing serious environmental challenges, especially due to anthropogenic impacts. This study evaluates the morphological, total vegetation, water index, and shoreline changes over the past two decades (2000 - 2020) using satellite images from Landsat TM, ETM, and OLI. The study area is continuously changing at a frightening rate due to anthropogenic and natural activities. The analysis of changes in the Coastal region of Kachchh, Gujarat revealed significant variations in the form of vegetation and shoreline Changes. In addition, land-use/land-cover (LULC) maps for the study area for the years 2000 and 2020 are prepared using band ratio as a pre-classification step, followed by a combination of supervised and non-supervised classification. An accuracy assessment is performed for each dataset and the overall accuracy is between 90 - 95%. The LULC study is carried out to identify different sections in the region that are vulnerable to environmental degradation. This study indicates that the Coastal region of Kachchh, Gujarat is under extreme pressure due to the rapid development of the surrounding artificial landscape, where socioeconomic factors coupled with changes in the near environment as well as the reproduction of salt production affect the quality in the coastal ecosystem. affect activities. For coastal protection, the government initiated socio-economic activities, designed strict management policies and awareness programs for local communities about the importance of coastal protection and management. The maps produced in this research will contribute to both the development of a sustainable land use plan as well as shoreline conservation measures, which will further aid in sustainable future development in the region
