P1. Section B case study Flashcards
what is the case study for hot deserts?
Thar desert in India
what are the 4 opportunities the Thar desert brings?
- mineral extraction
- tourism
- farming
- energy
what are 4 examples of minerals extracted at the Thar desert
- Limestone
- Gypsum –> used in making plaster and cement. (construction)
- Feldspar –> used to make ceramics ( plates/ mugs)
- Kaolin –>used to make paper white
how has limestone helped with developing India
At Jaisalmer, limestone is mined, which is used in India’s steel industry . This industry produces billions of pounds each year and Tata steel used some of this money to purchase Jaguar Land Rover
How is tourism in the Thar an opportunity for India?
Tens of thousands of people visit each year. Local people in areas such as Jaisalmer have become tour guides and opened accommodation for tourists.
Desert safaris on camels have become very popular
What are 4 sources of energy the Thar provides
- Coal is burnt to produce energy and power plant has been constructed at Giral
- Oil was recently discovered in Barmer –> provides hundreds of jobs –> boosts the local economy
- Wind energy
- desert is very windy
- Jaisalmer wind farm has been built which is the largest in India - Solar farms have been built at Bhalari
Farming
what are the 3 challenges of the Thar desert?
- Extreme temperatures
- Water supply
- Inaccessibility
how is extreme temps a challenge in the Thar?
- High tales of evaporation leads to water shortages
- Farmers and outdoor workers are less productive due to the heath –> means less products produced to sell
How can the challenge of extreme temps in the Thar be overcome?
Farmers can work early in the morning and late at night when temperatures are much lower
how is water supply a challenge in the Thar?
has low levels of rainfall and very few rivers that rub through the desert e.g River Luni, but they do not flow all the time
- less water to grow crops
- lower crop yield
How can the challenge of low water supply in the Thar be overcome?
Irrigation
- water can be taken from the Indira Gandhi Canal to water the crops
- However causes Salinisation
how is Inaccessibility a challenge in the Thar?
high temperatures causes the tarmac to melt and strong winds often blows sand over the roads
- People and equipment unable to access the desert for mineral extraction which requires heavy equipment.
How can the challenge of inaccessibility in the Thar be overcome?
Transport has been adapted to the deep sand and hot temps.
- Trucks known as ‘Kekras’ which have huge tyres
- Camels
How many countries does the Saharan Great Green Wall span across?
11 countries
