- Hot Deserts Thar Desert
- Challenges
- Extreme Temprature
- The temperature can exceed 50 degrees in the summer making it harder to mine farm and be tour guides. This makes development more difficult.
- Water Supply
- Only 120-240mm of rain falls per year so the water must be used efficiently and sustainably.
- Over irrigation has occured in some parts. The waterlogged ground's water dries up leaving salt behind which makes it harder to grow crops.
- Inaccessibility
- The desert covers 200000 sq km
- Poor infrastructure matched with extreme environmental conditions makes most parts inaccessible
- This boosts the rich and poor divide. Tourists only go to accessible places such as Jaisalmer but not the other places which are poorer.
- Extreme Temprature
- Opportunities
- Tourism
- Important source of income. Creates jobs for people.
- Jaisalmer - located on an ancient trading highway. (East to West)
- Tourists explore the desert on camels with local guides.
- Mining
- Valuable reserves of minerals such as gypsum.
- Limestone and Marble are quarried which are used in building and construction.
- The minerals are used to produce a variety of things such as cement and fertilisers.
- Energy
- Wind energy - Turbines
- Renewable energy such as solar panels are used to desalinate.
- Farming
- Irrigation has made it possible for large scale farming.
- Producing crops such as wheat and cotton has created jobs and generated income for the local economy.
- Mini drainage basins allow rain water to collect for grazing animals.
- Tourism
- Characteristic
- Sandy, infertile soil. Little organic matter.
- NW India into Pakistan. Most densely populated desert.
- Sandy hills, Sand dunes, Small trees and shrubs
- Desertification
- Reducing risk of desertification
- Growing crops that don't need much water- reduces water use.
- Using drip irrigation on crops
- Means soil isn't eroded by lots of water being added in one go.
- Using drip irrigation on crops
- Growing crops that don't need much water- reduces water use.
- Causes
- Climate Change
- Higher temperatures so more evaporation.
- Makes the soil drier - plants die - roots don't hold soil together anymore.
- Less rainfall
- Less water for plants to grow so they die.
- Roots hold soil together, plants die= Soil is easily eroded
- Higher temperatures so more evaporation.
- Climate Change
- Reducing risk of desertification
- Challenges
