- W3194765896 abstract "The recent world is witnessed an increasing trend of mining on the onshore sand deposits, including beaches for extracting titanium, thorium, pyrochlore, gypsum, barites, iron ore, clay and appetite, etc. Part of Kollam district, Kerala, 23 km coastline between Neendakara and Kayamkulam has blessed with titanium and thorium deposit, and sand mining is started in the year late 1960; since then, the area becomes converted into sea due to the overexploitation of the marine resource. In the present study, it examined shoreline positional changes within the 16 km of the coastline between Alappad and Chavara using Landsat 1, Landsat 4, Landsat 7 and Sentinel 2A for the corresponding years 1973, 1988, 1997, 2001, 2012 and 2019. The study observed that the area is under very hazardous situation. Among the 671 ha coastal area, around 85 hector land was dug out from the Alappad beach. Due to the mining process, chemicals are contaminated with freshwater sources, and coastal habitat is forced to migrate. The study also observed that the Vattakayal, one of the backwaters, which is situated parallel to mining area, departing to merge with the sea soon or later. The highest rate of erosion is observed between 2001 and 2012, around 42.81 hector land area become dismantled with sea, and around 3.90 hector beach was dug out in a year an average. The present study canvassed the horrible change experienced the study area. The study will give a benchmark to the policymakers who are still between the decisions. The study proves that the use of remote sensing and geospatial tools is coast effective and dynamic in nature which gives clear information within the time scale." @default.
