Aravalli Range (Ecological Significance and Protection)

Aravalli Range (Ecological Significance and Protection) क्या है?

The Aravalli Range is one of the oldest fold mountain ranges in the world, stretching approximately 692 km across Gujarat, Rajasthan, Haryana, and Delhi. It plays a critical role as a green lung, water recharge zone, and biodiversity hotspot in the semi-arid and arid regions of western India.

ऐतिहासिक पृष्ठभूमि

Geologically, the Aravallis are Precambrian in origin, formed during the Aravalli-Delhi Orogeny. Over millennia, they have been subjected to extensive erosion, resulting in their present-day relict form. Historically, they have influenced regional climate, hydrology, and human settlements.

मुख्य प्रावधान

9 points
  • 1.

    Geographical Extent: Runs from Palanpur (Gujarat) through Rajasthan and Haryana, ending near Delhi (Raisina Hill).

  • 2.

    Ecological Role: Acts as a natural barrier against the spread of the Thar Desert towards the east.

  • 3.

    Biodiversity: Home to diverse flora and fauna, including several endemic and endangered species. Contains important wildlife sanctuaries like Sariska Tiger Reserve and Mount Abu Wildlife Sanctuary.

  • 4.

    Hydrological Significance: Crucial for groundwater recharge and the origin of several rivers like Banas, Luni, Sabarmati. Its forests help in soil conservation and regulating water flow.

  • 5.

    Mineral Resources: Rich in minerals like copper, lead, zinc, and marble, leading to extensive mining activities.

  • 6.

    Threats: Faces severe threats from illegal mining, uncontrolled urbanization, deforestation, and encroachment, leading to habitat loss, soil erosion, and water scarcity.

  • 7.

    Protection Efforts: Various state and central laws like the Forest (Conservation) Act, 1980, Environment (Protection) Act, 1986, and state-specific regulations are in place. Judicial interventions, particularly by the Supreme Court, have been critical in its protection.

  • 8.

    Eco-sensitive Zone (ESZ): Parts of the Aravallis, especially around Protected Areas, are designated as ESZs to regulate developmental activities.

  • 9.

    Green Wall of Aravalli: A proposed initiative to create a 1,600 km long and 5 km wide green belt along the Aravalli range to combat desertification and enhance ecological services.
