Satellite audit reveals 31.8% of Aravalli hills at ecological risk due to new classification criteria
A satellite audit by a conservation collective has found that 31.8% of the Aravalli range is at ecological risk following a new Central government classification. The Centre fixed the height of hills at 100 metres for legal protection, which the group claims ignores geological reality and strips low-elevation zones of protection. These areas are critical water recharge zones and act as dust barriers for 30 crore people. The group demands a complete ban on mining in the Aravallis and that the entire range be declared a 'fully protected zone' regardless of elevation.
Key Points
- The 100-metre height threshold for legal protection leaves nearly one-third of the Aravallis vulnerable to mining.
- Aravalli hills serve as a vital barrier against the expansion of the Thar Desert into North India.
- The group used the Copernicus Digital Elevation Model (FABDEM) for their forensic analysis.
- Low-elevation zones are essential for groundwater recharge and maintaining the regional ecological balance.
Exam Facts
- 31.8% of Aravalli area falls below the 100m threshold for protection.
- FABDEM (Copernicus Digital Elevation Model) was used for the satellite audit.
- The Aravallis act as a barrier for approximately 30 crore people.
