The correct Answer is A-1, B-2, C-3, D-4
Explanation
This question assesses knowledge of specific geographical regions in India and their associated environmental constraints, which are often linked to their physical characteristics and human activities.
Statement-wise Analysis
- A. Bharmaur - 1. Harsh climate with low resource base
- Correct: The Bharmaur region, located in the Chamba district of Himachal Pradesh, is a tribal area inhabited by the Gaddis. It is characterized by a harsh climate, rugged terrain, and a low resource base, primarily due to its high altitude and mountainous environment.
- B. Thar Desert - 2. Fragile ecosystem with shifting sand dunes
- Correct: The Thar Desert, also known as the Great Indian Desert, is characterized by an arid to semi-arid climate, sparse vegetation, and a fragile ecosystem. Shifting sand dunes are a prominent geomorphological feature of this region, contributing to its environmental vulnerability.
- C. Rayalaseema - 3. Frequent drought situations
- Correct: The Rayalaseema region in Andhra Pradesh is known for its semi-arid climate and is frequently affected by drought conditions. This is primarily due to its location in the rain shadow region and dependence on erratic monsoon rainfall.
- D. Nilgiris - 4. Plantation-driven land pressure
- Correct: The Nilgiris, a mountain range in Tamil Nadu, are renowned for their tea and coffee plantations. These extensive plantations have led to significant land-use changes, deforestation, and increased pressure on the natural ecosystem, including biodiversity loss and soil erosion.
Key Takeaway
Geographical regions often exhibit distinct environmental constraints directly influenced by their climate, topography, and dominant economic activities.
