Supreme Court forms high-powered expert panel to re-examine Aravalli definition
The committee will assess if the Aravalli hills over 100 metres high form a continuous ecological area despite exceeding the proposed 500-metre gap and whether mining should be allowed in those spaces

Context
The has constituted a high-powered committee (HPC) chaired by the Director General of the (ICFRE) to independently review the definition and delineation of the Aravalli hill range. This follows a stay on an October 2025 report by a (MoEFCC) committee, which the Court deemed to possess 'critical ambiguities' regarding the ecological and scientific assessment of the region, potentially facilitating environmentally disruptive activities like mining.
UPSC Perspectives
Environmental Policy & Law
The central issue revolves around the precise ecological definition of the Aravallis, a critical geographical feature functioning as a climatic barrier against the advancing Thar Desert. The is evaluating the environmental impact of a previous committee's recommendation that limited the definition of the Aravalli range to areas located within 500 metres between two or more hills, and hills with elevations of 100 metres and above. The newly formed HPC must assess whether this restrictive definition narrows the extent of protected territory, potentially circumventing the and facilitating mining. This highlights the concept of ecological contiguity, where even physically separated geological formations function as a unified ecosystem. If the 500-metre threshold is applied, significant intervening gaps could lose protection, fracturing the ecosystem and undermining orders dating back to the landmark which broadly defined 'forests' based on their dictionary meaning.
Judicial Review & Governance
The formation of the HPC illustrates the 's proactive use of judicial review (the power to examine the constitutionality or legality of executive actions) in environmental governance. By staying the report of a committee chaired by a Secretary-level official of the and instituting an independent body of domain experts, the Court is exercising an activist role to safeguard (Right to Life), which inherently includes the right to a clean environment. The Court's insistence on a 'fair, impartial and independent expert opinion' underscores a lack of confidence in executive assessments when they potentially compromise environmental integrity for developmental or commercial interests (like mining). This scenario is a classic example of environmental jurisprudence, where the judiciary intervenes to ensure that scientific rigor, rather than bureaucratic expediency, dictates environmental policy and regulatory frameworks.
Geography & Geomorphology
From a geographic perspective, the Aravallis are one of the oldest fold mountains in the world, stretching roughly 692 km across , , , and . The debate over the 100-metre elevation criterion (where only 1,048 of Rajasthan’s 12,081 hills allegedly qualify) is critical for geomorphological mapping. The Aravallis are highly eroded and relict mountains; therefore, strict elevation thresholds might exclude significant portions of the original landform that still perform crucial ecological functions, such as groundwater recharge and preventing desertification. The HPC's task is to determine if these lower-elevation hills are geologically and ecologically contiguous with the main range. From a UPSC mapping perspective, understanding the extent, spread, and ecological significance of the Aravallis, especially their role as a water divide and a barrier to the eastward expansion of the Thar desert, is paramount.
