How has the building of dams created conflict for countries that shared rivers?
How have the major rivers of SW Asia become a part of political conflict? Dams built along the rivers have caused problems for people living further downstream because less water comes down the river to those people once the dam is built.
How has the access to rivers in southwest Asia led to conflicts between countries?
Quick Summary: Much of Southwest Asia is desert, so there is not a lot of water to use for drinking and irrigation. Water is not equally distributed; close to none of the countries in Southwest Asia have a good water source; this has been the cause for many clashes, including the 6 Day War, which was fought over water.
What are the causes of water pollution in Southwest Asia?
Increased demand for irrigation to expand farming has led to overuse of rivers and streams. Many farmers have begun to use chemical fertilizers, which have contaminated water supplies through runoff into these same rivers and streams.
Why does water pollution impacts irrigation and drinking water?
“Polluted runoff is created by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into watersheds via lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water” (1).
Who has the worst water pollution?
- Eritrea: 80.7% lack basic water services.
- Papua New Guinea: 63.4% lack basic water services.
- Uganda: 61.1% lack basic water services.
- Ethiopia: 60.9% lack basic water services.
- Somalia: 60% lack basic water services.
- Angola: 59% lack basic water services.
- Democratic Republic of the Congo: 58.2% lack basic water services.
What impact does industry have on water pollution?
High quantities of nutrients in water from industrial crop fertilizers and animal waste cause excessive aquatic plant growth — a process known as “eutrophication,” which, in turn, causes “hypoxia,” or water that is low in oxygen.
