Government's New Definition of Aravalli Hills Aims to Curb Illegal Mining

Union Environment Minister Bhupender Yadav has announced a new definition for the Aravalli Hills, aimed at curbing illegal mining activities. This redefinition, approved by the Supreme Court, classifies hills based on their height, raising concerns among environmentalists about the potential ecological impact. Critics, including Congress leaders, argue that this could jeopardize the region's ecological balance. Yadav insists that the government's commitment to protecting the Aravalli range remains strong, emphasizing sustainable mining practices. The debate continues as stakeholders assess the implications of these changes on the environment and local communities.

Union Minister Addresses Aravalli Hills Redefinition

On Monday, Bhupender Yadav, the Union Environment Minister, asserted that the recent redefinition of the Aravalli Hills is intended solely to combat illegal mining activities in the region. He emphasized the commitment of the Narendra Modi administration to safeguard and restore this vital mountain range.

Yadav reiterated that mining is strictly prohibited within the National Capital Region.

The Aravalli mountain range, which spans approximately 700 kilometers from southwestern Gujarat through Rajasthan to Delhi and Haryana, features its highest peak, Guru Shikhar, at an elevation of 1,722 meters.

According to the new definition approved by the Supreme Court, an Aravalli hill is classified as any landform that rises at least 100 meters above the surrounding landscape. An Aravalli range consists of two or more such hills located within 500 meters of each other, including the intervening land.

Environmental advocates have raised concerns that this height-based definition may leave many lower, ecologically significant hills vulnerable to mining and development. Experts argue that these smaller hills play a crucial role in preventing desertification, replenishing groundwater, and supporting local communities.

Yadav stated that the new definition aims to facilitate 'sustainable mining legally' and assured that no new mining leases would be issued until a comprehensive Management Plan for Sustainable Mining is established.

He noted that only 0.19% of the entire Aravalli area is potentially available for mining.

The minister accused the Congress party of disseminating misinformation regarding the issue, claiming that they had previously allowed unchecked illegal mining in Rajasthan.

The Congress party has criticized the new definition, warning that it could lead to severe ecological repercussions for the region. Congress leader Pawan Khera expressed concerns about the potential destruction of the ecological balance in the National Capital Region and surrounding areas.

Khera stated, 'If the new order regarding the Aravallis is enacted, it will devastate the ecological balance of this entire region, affecting several states and half of India.'

Another Congress leader, Sachin Pilot, voiced his worries, questioning what legacy would be left for future generations if illegal mining persists.
