The Reason The Nation's Aravalli Mountain Range Have Become the Epicenter of Increasing Protests.

Protests have erupted 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.

According to the fresh parameters, approved by the court following central government recommendations, an Aravalli hill is any geographical feature with a minimum elevation of 100 metres (328 ft) above the adjacent land. A cluster of such hills within 500 metres of each other, combined with the land between them, are deemed to be an Aravalli range.

Conservationists contend that defining Aravalli hills based on elevation could leave many lower, scrub-covered but vitally important hills unprotected from quarrying and development.

The central administration, on the other hand, says that the new definition is meant to strengthen regulation and establish consistency and not dilute protections.

What is Sparking the Demonstrations?

This weekend, calm demonstrations occurred in cities such as Gurugram and Udaipur, led by community members, farmers, green activists, and, at times, lawyers and political parties.

A founder member of a prominent conservation collective remarked that the new definition threatens to compromise the essential function of the Aravalli range in "preventing desertification, recharging groundwater and safeguarding local economies" in northwest India.

The shorter, vegetated hills play a vital role in preventing desertification, recharging groundwater and sustaining communities according to experts.

"This mountain system must not be categorized by height alone, but by its ecological, geological and climatic role," noted an ecology advocate associated with the movement to save the Aravallis.

He said that, internationally, mountains and hill systems are classified by the functions they perform, not by arbitrary elevation thresholds.

"Any landform that is structurally a component of the Aravalli system and plays a critical role in ecology or preventing desertification must be acknowledged as a component of the system, irrespective of its height."

Protesters are calling for that the government define Aravalli areas using scientific criteria, including topography, ecology, wildlife connectivity and climate resilience.

One activist warned that the court's new definition could encourage extractive industries, development and business projects, increasing the threat of ecological damage.

Political opponents have stepped up criticism, warning that the new definition might lead to significant environmental degradation.

One political leader said that protecting the Aravallis is "fundamentally linked to Delhi's survival." Another leader described the range the state's "life-support system," stating that without it, "the entire area up to Delhi would have become a desert."

What Does the Government Say?

India's central government has sought to downplay these concerns.

In a recent communication, it said the new definition is intended to strengthen regulation and create standardization, adding that a clear, unambiguous definition was needed to oversee extraction consistently across states.

It further stated that the new definition encompasses the whole mountainous region – incorporating slopes, related features, and intervening areas – explicitly protecting hill clusters and their linkages.

The federal environment ministry said it is incorrect to assume 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 existing ones can continue if they follow sustainable mining norms.

It added that mining remains prohibited in core "inviolate" areas – protected forests, environmentally fragile zones, and wetlands – except for certain essential, national security, and nuclear minerals allowed by law.

The Environment Minister indicated only about two percent of the vast Aravalli range could potentially be mined, and only after comprehensive assessments and official approval.

However, several of the protesting groups contend that protests will persist and that they are considering legal options to contest the court's new definition.
