Hot Deserts 2 Flashcards
Sahara Desert case study
List the development opportunities in hot deserts
-Mineral extraction
-Energy
-Farming
-Tourism
Name your hot desert case study:
The Sahara Desert
How is farming a development opportunity in the Sahara desert?
-Economic opportunities for development may include farming on the river Nile
-The river is a stable water source running through the Sahara desert
-This means that water can be supplied to crops on farms all year round using irrigation techniques
-Which means that farmers can battle the severe lack of rainfall
The Aswan Dam, Egypt
On the Nile, makes water extraction from the river easier, allowing farmers to battle the severe lack of rainfall.
Where does the majority of people in Egypt live?
95% of Egypt’s population live within 10k of the Nile
How is tourism a development opportunity in the Sahara Desert?
-Tourism provides job opportunities.
-This means an income not just for the country, but for individuals.
-Which means their quality of life can improve
Where does tourism happen in hot deserts?
Usually happens on the fringes of deserts, close to Urban areas.
How is energy a development opportunity in the Sahara Desert?
-Hot deserts like the Sahara receives an average of 10hrs of bright sunlight a day, ideal for solar power generation.
-This means that countries can have a clean and cost-effective energy source.
-Which means that not only will they save money in the long run (solar power is one of the cheapest energy sources once solar farms are built), but the countries may look more attractive.
-This is because they are contributing less to CO₂ emissions as they are burning fewer or no fossil fuels
-this could be advantageous in their development over other countries
How is mineral extraction a development opportunity in the Sahara Desert? (basic level)
-Desert sands are rich in minerals, which can be mined and exported as primary products for profit.
-For example, the extraction and exporting of the mineral phosphate in Morocco.
-This means that money is made and can be invested into improving things like schools and healthcare
-Which means that peoples’ quality of life can improve.
How is mineral extraction a development opportunity in the Sahara Desert? (advanced level aka the continuation)
-Some of the money, however, could be re-invested into industry, perhaps in building factories
-Here, raw materials could be manufactured into secondary products (e.g. fertilisers from phosphate).
-These could be exported at a higher price, which would bring even more money into the country for further investment, which means the country could develop further.
List the challenges of developing hot desert environments:
-Extreme temperatures
-Water Supply
-Inaccessibility
How are extreme temperatures a challenge to development?
-In hot deserts there is an extreme diurnal range (0-45°C) and exposure to temperature extremes such as these can be dangerous.
-Physical work can be difficult, which means that opportunities for development such as farming and mining are limited.
-The hot season can be too hot for tourists, which means employment in the tourism industry can be seasonal
How is water supply a challenge to development?
Rainfall in hot deserts is low and unpredictable which makes farming difficult for a number of reasons.
1-Water is needed for plants to photosynthesise and hence grow
2-Desert sands are dry and infertile
3-Nutrient cycling is slow as moist conditions are better for bacteria to thrive
What are deep boreholes for/ what do they do?
Deep boreholes extract water stored under the Sahara without replenishing it (unsustainable).
Water pipes
Built to help extract valuable desert resources. (links to Morocco).
