The Reason The Nation's Aravalli Hills Have Become the Epicenter of Increasing Demonstrations.

Unrest has flared across northern India after the nation's top court redefined the Aravalli hills – among the planet's most ancient geological formations stretching across the states of Rajasthan, Haryana, Gujarat, and the capital territory.

As per the revised criteria, endorsed by the court based on central government recommendations, an Aravalli hill is any geographical feature rising at least 100 metres (328 ft) above the surrounding terrain. A cluster of such hills within 500 metres of each other, along with the land between them, are deemed to be an Aravalli range.

Ecologists assert that classifying Aravalli hills based on elevation risks leaving numerous lower, scrub-covered but ecologically critical hills unprotected from quarrying and development.

The central administration, on the other hand, states that the revised definition is designed to enhance oversight and bring uniformity and not weaken safeguards.

What is Sparking the Demonstrations?

Recently, peaceful protests occurred in cities such as Gurugram and Udaipur, led by community members, farmers, green activists, and, in some cases, lawyers and political groups.

An organizing member of a prominent conservation collective commented that the new definition risks undermining the critical role of the Aravalli range in "halting desert expansion, replenishing aquifers and protecting livelihoods" in northwest India.

The shorter, vegetated hills perform a crucial function in stopping desert creep, boosting water tables and supporting livelihoods as per experts.

"This mountain system should not be defined solely by elevation, but by its environmental, physical and weather-related role," said an environmental activist associated with the campaign to preserve the Aravallis.

He pointed out that, internationally, mountains and hill systems are classified by the roles they play, not by arbitrary elevation thresholds.

"Any feature that is geologically part of the Aravalli system and serves a vital purpose in the ecosystem or combating desertification should be recognised as a component of the system, irrespective of its height."

Protesters are calling for that the government delineate Aravalli areas using research-based parameters, encompassing geography, biodiversity, wildlife connectivity and climate resilience.

A campaigner cautioned that the court's new definition might promote extractive industries, development and business projects, heightening the threat of ecological damage.

Political opponents have stepped up criticism, warning that the new definition could cause significant environmental degradation.

One political leader said that protecting the Aravallis is "inseparable from Delhi's survival." A different official called the range the state's "life-support system," stating that without it, "the entire area up to Delhi would have turned into a desert."

What Does the Government Say?

India's federal government has attempted to minimize these concerns.

In a recent statement, it asserted the new definition is meant to strengthen regulation and bring uniformity, adding that a clear, unambiguous definition was needed to oversee extraction uniformly across states.

It added that the new definition encompasses the entire hill system – including slopes, related features, and connecting zones – clearly safeguarding hill clusters and their linkages.

The federal environment ministry said it is wrong to presume that mining will be allowed on all landforms under 100 metres.

The government states areas inside the Aravalli hills or ranges are excluded from new mining leases, while current operations can continue if they adhere to environmentally sound practices.

It added that mining remains prohibited in core "inviolate" areas – reserved woodlands, eco-sensitive zones, and wetlands – except for certain essential, national security, and nuclear minerals permitted by law.

The minister responsible for ecology said only about two percent of the 147,000 sqkm Aravalli range could potentially be mined, and only after detailed studies and formal clearance.

Nevertheless, several of the protesting groups say that protests will persist and that they are exploring legal options to challenge the court's new definition.
