The Supreme Court is set to hear a crucial case today regarding the definition of the Aravalli Hills, with a bench headed by the Chief Justice of India (CJI) presiding. The dispute centers on whether only hills above 100 meters should be considered part of the Aravalli range. Environmentalists argue that if the 100-meter threshold is strictly applied, over 90% of the Aravalli mountain range would fall outside the definition, putting the entire natural ecosystem at risk. The 20 November 2025 recommendation by the central government had defined hills above 100 meters as Aravalli, but experts warn that this could lead to the destruction of biodiversity, an increase in illegal mining, and severe environmental consequences for Delhi-NCR, Haryana, and Rajasthan. Protests have been held in multiple states, with activists demanding stricter conservation measures. The Supreme Court has taken suo motu cognizance of the matter, reflecting the growing public concern over potential ecological damage. Authorities, environmental experts, and citizens are closely monitoring today’s hearing to see whether the definition will be reconsidered and how protection measures for the Aravalli Hills will be enforced.
