📖 Introduction
Recent Findings on Aravalli Degradation
A recent scientific study on land use dynamics in the Aravallis has brought to light the severe threats facing this ancient mountain range. The study highlights significant environmental damage.
The ongoing destruction has led to considerable biodiversity loss, widespread soil degradation, and a marked reduction in vegetation cover across the region.
UPSC Prelims/Mains: Understanding such studies is crucial for questions on environmental degradation, biodiversity conservation, and sustainable development in India.
Quantifying the Decline of the Aravallis
The study provides stark figures illustrating the physical disappearance of the Aravalli hills between 1975 and 2019. This period saw substantial changes in the landscape.
- 8% (approximately 5,772.7 sq km) of the entire Aravalli range has completely vanished.
- Much of this lost area has transformed from rock to barren land.
- An additional 19% of the range has been converted into human settlements.
This rapid transformation underscores the intense anthropogenic pressure on the fragile ecosystem of the Aravallis.
Rising Desertification Risk
The degradation of the Aravallis poses a critical threat, particularly concerning the expansion of the Thar Desert. The mountain range acts as a natural barrier against desertification.
With the weakening of this natural barrier, the Thar Desert is increasingly expanding towards the National Capital Region (NCR). This has severe environmental consequences.
The expansion exacerbates existing problems such as air pollution, accelerates desertification processes, and contributes to more erratic weather patterns in the region.
Primary Cause: Unchecked Urbanization
One of the most significant drivers of Aravalli degradation is the relentless surge in urbanization. The demand for land and resources from growing cities is immense.
- In 1975, settlements accounted for only 4.5% of the Aravalli region.
- By 2019, this figure dramatically increased to 13.3%.
This substantial increase is primarily driven by unchecked urban expansion, leading to encroachment, construction, and resource extraction within the ecologically sensitive Aravalli range.
💡 Key Takeaways
- •Aravallis are rapidly degrading: 8% vanished, 19% converted to settlements (1975-2019).
- •Degradation accelerates Thar Desert expansion towards NCR, worsening pollution and erratic weather.
- •Unchecked urbanization (settlements up from 4.5% to 13.3%) is a primary cause.
- •Aravallis are critical for NCR's air quality, water security, and biodiversity.
- •Illegal mining and real estate encroachment are major threats to this ancient mountain range.
