The Aravalli Range, stretching across Rajasthan, Haryana, and Delhi, is one of the oldest mountain systems in the world—and one of India’s most ecologically critical yet endangered landscapes. Often dismissed as barren hills, the Aravallis play a vital role in groundwater recharge, climate regulation, biodiversity conservation, and desertification control in north-west India.
From Supreme Court judgments and government reports to the writings of environmentalists, scientists, and public intellectuals, the importance of the Aravalli hills has been repeatedly acknowledged and documented. Legal experts warn that their destruction could have irreversible consequences, while environmental thinkers describe them as a natural shield protecting Rajasthan and the Delhi-NCR from advancing desertification, water scarcity, and extreme climate impacts.

The message emerging from these 50 documented quotes is clear and consistent: the Aravalli range is not wasteland, but a life-support system for millions of people across Rajasthan and northern India. From acting as a natural barrier against the Thar Desert to recharging aquifers, moderating climate, and sustaining biodiversity, the Aravallis perform ecological functions that no artificial intervention can fully replace.
What makes these voices especially significant is their diversity—judges, scientists, environmentalists, policy experts, and conservationists—all arriving at the same conclusion through different disciplines and experiences. The repeated warnings from courts and experts underscore that continued mining, deforestation, and land-use change in the Aravallis threaten not just local ecosystems, but regional environmental security.
