The Aravalli Hills, stretching across North India, are among the oldest geological formations on Earth. They are vital for groundwater recharge, biodiversity, and climate regulation, supporting millions of people and countless ecosystems.
A recent proposal threatens these hills by redefining them solely based on height — only landforms above 100 metres would remain protected. This narrow, elevation-based definition would exclude nearly 90% of the Aravalli landscape from legal safeguards, exposing it to mining, construction, and deforestation.
If allowed, this redefinition would not only destroy fragile ecosystems but also undermine India’s climate commitments, worsen air and water quality, and intensify environmental disasters like heatwaves, dust storms, and desertification.
The Aravallis are more than hills — they are India’s climate spine, and losing them would have irreversible consequences for our environment, health, and future generations.
The Aravalli Hills, one of the oldest geological formations on Earth, are critical for India’s environment and climate. They:
Recharge groundwater for millions of people 💧
Control desertification and soil erosion 🌱
Maintain biodiversity corridors 🐾
Regulate local and regional climate 🌬️
Height is not the measure of their importance. Even low-relief hills are essential ecosystems that protect our cities, villages, and future generations.

A recent proposal seeks to redefine the Aravallis based solely on elevation: only hills above 100 metres would remain protected.
This would:
- Exclude nearly 90% of the Aravalli landscape from legal protection
- Open the door to mining, construction, and deforestation ⛏️🌲
- Endanger water security, air quality, and public health
- Intensify heatwaves, dust storms, and climate stress, especially in Delhi-NCR
Such a definition ignores ecological reality, hydrology, and climate science, putting millions of lives and ecosystems at risk.

The Aravallis are India’s climate spine. Weakening their protection directly undermines India’s Net Zero and climate commitments, including:
