ARAVALI RANGE : ENVIRONMENT

NEWS :  Illegal mining, encroachments, deforestation a threat to Aravali as natural green wall

 

WHAT’S IN THE NEWS ?

The Aravali range  is facing a severe threat from illegal mining, deforestation, and human encroachments, which have led to environmental degradation as well as depletion of groundwater reserves in the region. 

 

Aravali Range :

  • Location: Extends 692 km with a width of 10-120 km; forms an ecotone between Thar Desert and Gangetic plain.
  • States Covered: Rajasthan (80%), Haryana, Delhi, and Gujarat (20%).
  • Geography: Rugged hills, rocky outcrops, sparse vegetation.
  • The range comprises over 500 hillocks, and the altitude of its highest peak, Guru Shikhar in Mount Abu
  • Significance:
  • Acts as a natural barrier against desertification.
  • Regulates climate and supports diverse ecosystems.
  • Watershed for rivers like Sabarmati, Luni, and Banas.

 

Environmental Concerns:

  • Forest Area Decrease: From 1999-2019, forest cover decreased by 0.9% over 75,572.8 sq. km.
  • Mining Expansion: Mining area increased from 1.8% in 1975 to 2.2% in 2019, especially in districts like Jaipur, Sikar, Alwar, etc.
  • Carbon Flux: High positive carbon flux in regions with high rainfall and protected areas. The southern part is greener due to less population and anthropogenic disturbances.

 

WAYAHEAD:

  • LiDAR-Based Survey: A LiDAR drone survey is needed for identifying and mitigating illegal mining activities.
  • Aravali Development Authority: An independent authority should be established for sustainable preservation.
  • Mining Ban: Implement a ban on all forms of mining in the Aravali region to protect its ecology and biodiversity.
