The vegetation cover and pattern in a vegetated area denote the environmental, biological, and ecological conditions and biodiversity richness over that area. Particularly, healthy vegetation increases the oxygen level and decreases evapotranspiration (ET), which reduces the public health-related problems. Previously, the green space was reducing soil salinity and soil erosion and increasing soil moisture, but land transformation and deforestation have been hammering the natural environmental condition. Finding the inland fishing area and vegetation area over the Gosaba CD block in India is the primary goal of this study. Different spectral indicators (vegetation and water indicators) have been utilized to define the vegetation and inland fisheries region, while Sentinel-2 multispectral data was used to delineate the land use and land cover (LULC). The results showed that 30.73 km2 (8.47%) area and 28.73 km2 (7.92%) area were covered by vegetation and inland fishery. After super cyclone “Aila,” this area faced a huge amount of saltwater intrusion and covered vegetation into inland fisheries area. The north, central, and southern parts were notified vegetated areas, and eastern, south, central, and northern parts were located in the inland fisheries area in 2020 using Sentinel-2 data. The South 24 Parganas coastal areas recorded a progressive alteration in climate, including flooding, saltwater intrusion, and many other issues. As a result, using high-resolution data, this study can assist in identifying the water regions in the Gosaba block. For appropriate management and planning of sustainable agricultural growth, this study is beneficial to local planners, administrators, and other stakeholders.
