Water issues in sw asia

  1. 1. Explain how water pollution and the unequal distribution of water impacts irrigation and drinking water. SS7G6
  2. 2. Water issues Water is unevenly distributed (not equally shared)in the Middle East Most countries like Saudi Arabia have almost no water and are mostly desert Turkey and Iraq share the Tigris and Euphrates rivers Israel, Syria, and Jordan share the Jordan river These countries need water to farm and raise animals so irrigation is very important
  3. 3. Water issues cont’d Farmers struggle to have enough water so many types of irrigation are used in the Middle East. Some examples include: Underground aquifers-layers of underground rock where water runoff form rains and streams is trapped. Fossil water wells- drilling for water that has been underground for centuries Israel and Saudi Arabia uses: Drip irrigation- using a computer that measures out how much water each plant receives Desalination- the process of removing salt and other chemicals from seawater Why do you think just Israel and Saudi Arabia? $$$$$$
  4. 4. Water issues cont’d Water pollution is a growing problem in the Middle East Chemical fertilizers used for farming can runoff and contaminate streams and rivers Using too much chemical fertilizers can cause a build up in the salt levels of the soil which make it impossible to farm the land Effective ways to manage garbage and treat sewage also cause pollution problems in the Middle East
  5. 5. Water issues cont’d Access to water causes conflicts in the Middle East (that’s right, fighting over water) Middle Eastern countries share the rivers and often times build their own dams to produce hydroelectric power which limits the amount of water used further downstream
  6. 6. Pop Quiz 1. Which river do Syria, Israel, and Jordan share? a. Euphrates b. Jordan c. Nile d. Tigris
  7. 7. Pop Quiz 2. How has the building of dams created problems for countries sharing rivers in Southwest Asia? a.Dams are too expensive to build to be practical b.Dams limit the water available to countries further downstream c.Few countries have the technology needed to be able to build dams d.Countries in Southwest Asia are not allowed to build dams along shared rivers
  8. 8. Pop Quiz 3. What is one problem chemical fertilizers cause for farmers? a.Chemical fertilizers make farm animals sick b.Chemicals have led to build-up of salt levels in the soil c.Fertilizers are too expensive for anyone in Southwest Asia to use d.Few countries in Southwest Asia have factories to make fertilizers
  9. 9. Pop Quiz 4. How has the use of fertilizers affected water supplies in many countries in Southwest Asia? a.Use of chemical fertilizers means crops must be watered constantly b.Enormous amounts of water must be used to produce chemical fertilizers c.Water supplies have been contaminated by the chemicals through runoff from the fields d.Chemical fertilizers have had very little effect on local water supplies in Southwest Asia
  10. 10. Pop Quiz 5. Why isn’t desalination and drip irrigation used more in Southwest Asia? a.Most countries do not know about these technologies b.Drip irrigation is not very effective in a hot, dry climate c.Few countries in Southwest Asia have access to seawater d.These technologies are very expensive for the countries to use
