The Supreme Court’s decision to stay its earlier order accepting the Centre’s controversial 100 meter definition of the Aravalli range has opened a new chapter in India’s environmental governance. What was initially presented by the Union Environment Ministry as a technical reclassification has now been exposed as a deeply flawed attempt to dilute protections for one of the country’s oldest and most fragile ecosystems. The court’s intervention, welcomed by activists and opposition leaders, has simultaneously embarrassed the government and raised serious questions about the credibility of its environmental stewardship.

The Aravalli range, stretching nearly 700 kilometers from Gujarat to Delhi, is not merely a set of hills to be measured by elevation. It is a living ecological mosaic, performing critical functions such as temperature moderation, groundwater recharge, soil retention, and seed dispersal. By proposing to classify only landforms rising more than 100 meters above surrounding terrain as part of the Aravalli, the government risked stripping vast swathes of this system of legal safeguards against mining and construction. Critics warned that such a move could expose up to 90 percent of the range to exploitation, with consequences that would unfold slowly but irreversibly.

The Supreme Court bench led by Chief Justice Surya Kant, joined by Justices J.K. Maheshwari and Augustine George Masih, recognized the gravity of the issue. In a suo motu case, the bench stayed its earlier order and directed the formation of a new expert committee to comprehensively examine the definition of the Aravalli range. This was not just a procedural correction but a clear rebuke to the government’s attempt at simplification. The court emphasized that ecological functions cannot be reduced to geomorphological thresholds, underscoring the need for precaution in fragile landscapes.

Union Environment Minister Bhupendra Yadav, who had earlier championed the 100 meter definition, attempted to welcome the court’s decision. Yet his position has come under fire, with the Congress demanding his resignation. Jairam Ramesh, senior Congress leader, pointed out that both the Forest Survey of India and the Central Empowered Committee of the Supreme Court had opposed the redefinition. He described the court’s stay as an interim victory for the environment, not for any political party, but insisted that the struggle was far from over. His words highlighted the broader fault line: the government’s willingness to push through a definition that ignored expert advice and public concern.

Ecologists such as Dr. Salim Khan have explained why the government’s approach was fundamentally flawed. Many inter hill corridors, lower slopes, and seasonal stream systems do not rise above 100 meters, yet they are functionally critical to the integrity of the ecosystem. Excluding them risks overlooking components that sustain aquifer resilience and prevent desertification. Prof. Shivaji Sarkar added that the Aravallis, being ancient mountains with shallow hydrological systems, demand precaution rather than simplification. Disturbance of lower slopes and connected landforms could impair groundwater recharge, accelerating desertification across northern India.

The government’s insistence that safeguards remain in place has failed to convince critics. Directions issued to Delhi, Gujarat, Haryana, and Rajasthan to ban new mining leases were seen as reactive rather than proactive. Environmental activist Shantanu Dwivedi described the earlier acceptance of the redefinition as exposing the entire region to contamination and pollution. He warned that permitting mining or construction could effectively erase the ecological treasure of the Aravallis, undermining natural safeguards against air pollution and climate stress. The contradiction between the government’s rhetoric of long term environmental measures and its willingness to dilute protections has become glaring.

The episode also revealed inconsistencies in official communication. Ramesh cited a 2010 Forest Survey of India report that defined the Aravallis based on slopes of three degrees or more, including buffers and valleys. He also referred to a September 2025 communication from the FSI noting that even hills of 10 to 30 meters act as effective barriers against desertification. Yet the government pushed a definition that ignored these findings. The FSI later clarified that it had not conducted a study concluding that 90 percent of the Aravallis would be left unprotected, but conservation scientists stressed that the issue was less about percentages and more about ecological processes.

The notion of “sustainable mining” promoted by some policymakers was also challenged. Dr. Khan explained that compensatory afforestation cannot replicate mature ecosystems within fragile landscapes. Trees planted as offsets take decades to function ecologically, and this time lag is critical in systems like the Aravallis. The impacts extend beyond forests to soil quality, cropping patterns, and food security. Over time, ecological changes translate into social and livelihood disruptions, particularly for agrarian and pastoral communities dependent on these landscapes. Once ecological thresholds are crossed, recovery becomes uncertain and difficult to manage.

The Supreme Court’s stay has therefore done more than halt a redefinition. It has exposed the government’s missteps, its disregard for expert advice, and its vulnerability to political backlash. By attempting to simplify the definition of a complex ecosystem, the authorities risked undermining environmental safeguards, eroding public trust, and inviting judicial correction. The embarrassment is compounded by the fact that the Environment Minister, once a champion of the 100 meter definition, was forced to welcome its suspension. The contradiction between his earlier stance and his current position underscores the government’s lack of coherence.

The Aravalli episode is a reminder that environmental governance cannot be reduced to technical thresholds or political expediency. It demands respect for ecological complexity, transparency in decision making, and accountability to both science and society. The Supreme Court’s intervention has temporarily safeguarded the Aravallis, but the larger battle continues. For the government, the episode is an insult of its own making, a public questioning of its credibility, and a warning that environmental shortcuts will not withstand judicial scrutiny. For India, it is a call to protect an ancient mountain system whose ecological functions are vital not only to the environment but to the very ease of breathing for millions.
