Temporal evolution of land use-land cover changes, Focusing on present mariculture sites along the Moheshkhali Island, Bangladesh

The current study examines the land use and land cover analysis of Moheshkhali Island, along with the geographical alterations to the land and their most likely causes from 2001 to 2022. Four separate categories of land classes have been determined using remote sensing, and this study summarizes quantitative analysis to determine changes in each land class over a twenty two years period. The most concerning situation occurred in the land class is mangrove area, which has been losing 107 square (sq.) kilometer (km) to 60 sq. km annually between 2011 and 2022. The Moheshkhali area's hilly landscape is declining annually as a result of deforestation, unlawful hill cutting, and natural disasters. At the same time, it was discovered that mariculture fields were dramatically expanding in Moheshkhali channel. The results of this particular analysis may be helpful for the accurate planning and management of Moheshkhali Island. Designs, management, and programme monitoring at the local, regional, and national levels will be greatly improved by those land use/ land cover maps. Due to the fact that Moheshkhali Island is located in a powerful cyclonic zone in the Bay of Bengal, extensive mangrove planting in newly establishing tidal flats is highly advised for the island's safety.
