Land Use and Land Cover Changes using Geospatial Study in Kallakurichi District, Tamil Nadu, India (2015-2025)

Abstract

Rapid land transformation driven by urbanisation and agricultural expansion is reshaping environmental conditions in many developing regions. Monitoring Land Use and Land Cover (LULC) dynamics using geospatial technologies is therefore essential for sustainable resource management and regional planning. This study looks at how land in Kallakurichi District, Tamil Nadu, has changed since it became a separate district in 2019. By examining factors such as land slope, direction, and the health of plants and water bodies, the research explores how the area affects farming, urban growth, and forests. The results show that cities have grown rapidly, while farmland and water areas have shrunk, and that there is more empty land and forest, indicating significant changes since the district began. While studies cover broader areas, there is little research on Kallakurichi itself, especially its drought risk—a major concern for a place that depends on rainfall and tanks for water. The study suggests conducting more local research and maintaining regular photo records to better manage resources and plan. It also recommends working with people from different fields, engaging the community more, and using new mapping tools to help Kallakurichi grow in ways that benefit the environment.
