Thar Desert

Question 1

Q: Where is the Thar Desert located and what is its context?

Answer 1

The Thar Desert stretches across 200,000 km² of north-west India and Pakistan. It is the most densely populated desert in the world, with a landscape consisting of sandy hills and thorn forest vegetation.

Question 2

Q: What opportunities for mineral extraction exist in the Thar Desert?

Answer 2

: The desert has valuable reserves of gypsum (used for plaster/cement), feldspar (for ceramics), and phospherite (for fertiliser). Additionally, Sanu limestone at Jaisalmer is a primary source for India’s steel industry, and marble is quarried near Jodhpur for construction.

Question 3

Q: How is energy being developed in this hot desert environment?

Answer 3

Renewable energy is a major focus; the Jaisalmer Wind Park, built in 2001, is India’s largest wind farm. Non-renewable resources are also significant, including lignite coal used at the Giral thermal energy plant and a large oilfield discovered in the Barmer district.

Question 4

Q: What are the opportunities for farming in the Thar Desert?

Answer 4

Most residents are involved in subsistence farming, grazing animals and growing vegetables in small pockets. Commercial farming of wheat, cotton, and maize has been made possible by the 650km Indira Gandhi Canal, which provides irrigation to over 3,500 km² of land.

Question 5

Q: How does tourism contribute to the economy of the Thar Desert?

Answer 5

: Tens of thousands of people visit the desert each year, often using Jaisalmer as a “honeypot” site to experience camel treks. This provides significant local employment as guides or hotel staff, creating a multiplier effect for the regional economy.

Question 6

Q: Why do extreme temperatures pose a challenge for development?

Answer 6

Summer temperatures can exceed 50°C, making outdoor work like mining or farming physically exhausting. These high temperatures also cause massive evaporation rates, leading to critical water shortages for humans, livestock, and crops.

Question 7

Q: What are the challenges regarding water supply in the desert?

Answer 7

ainfall is very low (100–240 mm annually), and rivers like the River Luni are intermittent, flowing only after rare downpours. While some water is extracted from underground aquifers, it is often salty, of poor quality, and not a sustainable long-term source.

Question 8

Q: How does inaccessibility restrict development in the Thar Desert?

Answer 8

A: The limited road network is difficult to maintain because high heat causes tarmac to melt and strong winds frequently bury roads in sand. Consequently, many remote areas are only accessible by camel, and getting materials to development sites is expensive and slow.
