The Contemporary chapter aims to investigate Land depletion in Upper Bharathapuzha Basin, Tamil Nadu, using the Revised Universal Soil Loss Equation (RUSLE). By means of an unified approach of geospatial records and Geographic data platform, various aspects contributing to soil erosion, such as precipitation-induced erosion force, soil fragility, inclination of land, land use, and conservation efforts are incorporated for the analysis. The study identifies areas with steeper slopes, lower vegetation density, and higher land use intensity as more susceptible to erosion. Furthermore, the impact of soil conservation practices like terracing and afforestation is assessed for their effectiveness in reducing erosion. The current methodology offers a predictive framework for identifying regions vulnerable to landslides and floods, enhancing early warning systems for the affected areas, and managing the disaster. The insights obtained from the study onto design targeted soil conservation strategies. By implementing these strategies, the integrity of soil resources, water quality, and the ecosystem can be better preserved in this vital watershed area. These findings also support the decision-making for sustainable land use and socio-economic well-being in communities that rely on the Upper Bharathapuzha Basin. The study’s multidisciplinary approach aligns with broader efforts to address environmental challenges, promote resilience, and foster sustainable development in water-sensitive areas. The study supports the eco-resilience by addressing climate change, land degradation, and also proposes sustainable solutions.
