Abstract

Kanyakumari is the southernmost coastal district of India and the state of Tamil Nadu. Due to the rapid increase in the population, the district's land use and land cover areas experience enormous changes in the past few years. So, the study of Land Use and Land Cover Changes in the district is much required for the current scenario. Landsat 8 images were used for the supervised classification.
The cultivable cropland, barren land, beachface landcover and dune cover vegetation decrease in their area because of the rapid growth of urbanisation. The Fallow land, the plantation, saltpans, built-up area and the beach mining areas show an increasing trend in their areas in the study area. The plantation, the fallow land and the beach mining only increase a little in their area, but the saltpans and the built-up areas increase rapidly. The rapid increase of the saltpans and the built-up area show rapid urbanization in the study area. The unfettered changes in the LULC feature are alarming the coastal vulnerability in the Kanyakumari districts coastal villages. This study offers pilot information for sustainable coastal management and suggests planning to decrease coastal regions' risk and vulnerability.
