Water Pollution and Unequal Distribution of Water
http://www.youtube.com/watch?v=k3LH_2ur2LE
GPS and E.Q.GPS: SS7G6a. Explain how water pollution
and the unequal distribution of water impacts irrigation and drinking water.
E.Q.: How do water pollution and the unequal distribution of water impact irrigation and drinking water?
"Many of the wars of this century were about oil, but the wars of the next century will be about water."
–Former World Bank Vice President Ismail Serageldin
VocabularyIrrigation - To supply (dry land) with water by
means of ditches, pipes, or streams; water artificially.
Underground aquifers – layers of underground rock where water runoff from rains and streams is trapped.
Fossil water – water that has been underground for centuries
Desalination – the process of removing salt and other chemicals from seawater
Hydroelectric power – electricity produced from the energy of running water
WaterWater is a natural resource that is
unequally distributed in the Middle East.Turkey and Iraq share the Tigris and
Euphrates river systems.Israel, Syria, and Jordan share the Jordan
River.Saudi Arabia has almost no water and is
made up of mostly desert.Iran has access to rivers in some areas, but
is mostly desert.Irrigation is necessary for farming.
IrrigationMethods:
water wheels,irrigation ditches and canalsanimal power to lift water from
underground wells.Israel and Saudi Arabia use drip
irrigation – the use of computers that measure out how much water each plant receives.
Desalination is expensive and complex in technology.
Water PollutionWater pollution has been a growing problem
in the Middle East.Increased demand for irrigation causes
overuse of rivers and streams.Chemical fertilizers used by farmers have
caused contaminated water supplies.Constant planting and fertilizer use have led
to the build-up of salt levels in soil, which destroys the soil.
Many cities and towns have grown rapidly, but there are not many effective ways to manage garbage and treat sewage.
ConflictAccess to water causes conflict because
countries have to share.Water is unequally distributed across the
region.

Fresh water losses from 2003-2009 in SW Asia – note drought In 2007.
CRCT Test Prep pages 82-83233. Which river do Syria, Israel, and Jordan
share?A. EuphratesB. JordanC. NileD. Tigris
B. Jordan
CRCT Test Prep pages 82-83234. How has the building of dams created problems
for countries sharing rivers in SW 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 SW Asia are not allowed to build dams along shared rivers.
B. Dams limit the water available to countries further downstream.
CRCT Test Prep pages 82-83235. What is one problem chemical fertilizers cause for
farmers?A. Chemical fertilizers make farm animals sick.B. Chemicals have led to the build-up of salt levels in the soil.C. Fertilizers are too expensive for anyone in SW Asia to use.D. Few countries in SW Asia have factories to make fertilizers.
B. Chemicals have led to the build-up of salt levels in the soil.
CRCT Test Prep pages 82-83236. How has the use of chemical fertilizers affected water
supplies in many countries in SW 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 run-off from the fields.D. Chemical fertilizers have had very little effect on local water supplies in SW Asia.
C. Water supplies have been contaminated by the chemicals through run-off from the fields.
CRCT Test Prep pages 82-83237. Why aren’t desalinization and drip irrigation used
more in SW 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 SW Asia have access to seawater.D. These technologies are very expensive for the countries to use.
D. These technologies are very expensive for the countries to use.
