A comprehensive study conducted by a panel of experts has raised alarms about the potential ecological crisis that could arise from the proposed diversion of the Mahadayi River waters for the Kalasa–Banduri Nala project. The report warns that such a diversion could disrupt the hydrological balance of the Western Ghats, impacting nearly 500 sq km of sensitive forest and threatening biodiversity, rainfall patterns, and water security in North Karnataka. The Kalasa–Banduri project, aimed at supplying water to drought-prone areas, has been in the pipeline for nearly three decades but has faced restrictions from the Mahadayi Water Disputes Tribunal. The study highlights the increasing water demands driven by a surge in sugarcane cultivation, which is projected to expand from 25,000 hectares in 2005 to 96,000 hectares by 2025, consuming approximately 140 tmc ft of water annually. Additionally, the Navilutheertha dam has suffered significant siltation, losing 12 tmcft of its original capacity. The experts advocate for alternative measures, such as desilting the dam and improving irrigation practices, to enhance water availability without compromising the ecological integrity of the region.
