Significance of Aravalli Range

• Rich Source of Minerals: Non-ferrous minerals like Zinc, Gold, silver and ferrous minerals like Copper ore and lead.

• • Nonmetallic minerals and building stones like marble, limestone etc. 

• Rich Habitat of Biodiversity: it has rich biodiversity, hosting 300 native plant species, 120 bird species, and various unique animals such as jackals and mongooses. etc.

• Combat Desertification: The hills also moderated the wind velocity and checked the spread of the Indian Desert (Thar) towards eastern Rajasthan, Indo Gangetic plains, Haryana and Western UP.

• Important Drainage System: Aravallis have provided a watershed between the Indus basin in the North West and the Ganga basin in the East.

• Rich Forest acts as Green lungs: Its forested patches have acted as green lungs against the air pollution and soil erosion.

• Cultural: The hills and their forests retain cultural importance for local communities like the Gujjars.

Concerns of Mining in Aravalli Range

• Environmental Degradation:  Over 25% and 31 hill ranges of the Aravallis in Rajasthan have disappeared due to illegal quarrying. 

• • Loss of diverse flora and fauna, including leopards, striped hyenas, golden jackals, nilgais, and palm civets. 

• Rivers originating in the Aravalli like Banas, Luni, Sahibi, and Sakhi have become dry. 

• Ecological Impact: Digging or mining to significant depths punctures aquifers, disrupting water flow and resulting in the drying of lakes and the formation of new ones. 

• • Man-wild animal conflicts arise as natural forests along the Aravallis are lost. 

• Altered natural drainage patterns threaten the hydrological system and water table in the entire NCR region. 

• • Intergenerational Equity: 
    • The exploitation of natural resources in the Aravalli range will burden future generations, emphasizing the need for legal frameworks to ensure intergenerational equity. 
  • Prevalence and Impact of Mining: 
    • In the absence of proper industrialization and sustainable livelihood sources, communities rely on mining and ancillary industries for income. 
    • The demand for construction material in NCR and adjacent areas drives mining activities in the Aravalli. 

• • Implementational Challenges:
    • Ambiguous law: Regarding inappropriate ownership and the process of privatization of land, No clear defined definition of Forest in particular to the region per se.  

Way Forward 

• • Enforcement Measures: Strict implementation of court orders banning indiscriminate mining and construction activities can significantly mitigate the loss of hill ranges in the Aravalli region. 
  • Reforestation Initiatives: Reforestation efforts can restore the Aravalli to their original vegetation state, similar to the successful restoration undertaken at the Aravalli Biodiversity Park. 
  • The Great Green Wall Project: Inspired by Africa’s ‘Great Green Wall’ project, India’s ambitious plan aims to establish a 1,400km long and 5 km wide green belt stretching from Gujarat to the Delhi-Haryana border. 
    • This initiative addresses increasing land degradation rates and the eastward expansion of the Thar desert.

• Community Engagement with proactive support of Government: Idea exchanges, wok shop, Awareness campaign etc.
