Aral Sea Basic Facts/Recap Once the fourth largest freshwater
sea in the world at over 26,000 sq. miles, the words Aral Sea mean Sea of Islands.
Served Kazakhstan to the north, Uzbekistan to the south, and its fishing industry helped feed nearby Turkmenistan, Tajikistan and Kyrgyzstan.
Once fed by the Amu and Syr Rivers, until they were both diverted to support the cotton industry in Uzbekistan when the area was part of the former Soviet Union.
Resulting Tragedy The Aral Sea is now less than 10%
of its former size (26,000 sq. miles to under 2,500 sq. miles).
The Northern portion has been stabilized, but the Southern part is almost gone except a small strip in the west.
Summers are extremely hot and dry, and winters are longer and colder, making agriculture more difficult.
The combination of salination of the land, overuse of fertilizers, and testing of chemical weapons have left the land and water polluted and dangerous.
Improve and repair current irrigation
PROS Much of the water
could be saved, allowing farmers and the government to return about half of the river water to the Aral Sea
CONS It would be very
expensive. The major rivers are
located in multiple countries.
Description: It is estimated that up to 70% of water that is diverted for farming is wasted and simply evaporates because of
a poorly built irrigation system. For example, only 12% of the canals in Uzbekistan are resistant to water loss.
Desalinate what water is left
PROS It would make the
water healthy again for humans.
Fish and plant live would return to the sea.
CONS It would be extremely
expensive, and in countries that cannot afford it.
It would use a lot of energy that could be bad environmentally.
Description: Much of the water in the Aral Sea right now is too salty for humans or animals. The water could go through the
desalination process, making it fresh water again.
Charge farmers for water
PROS Farmers would stop
wasting water they don't need.
It would generate income that could be used for restoration efforts.
CONS Farmers might stop
farming if it became too expensive.
Description: The government is currently providing the water for free to encourage farmers to keep farming. They could start
charging fees, which would decrease water waste as farmers would not want to pay for what they aren't using.
Use hybrid and drought resistant crops
PROS Plants would use less
water.
CONS Other varieties tend
to be more expensive for farmers to purchase.
Some people do not like scientifically created crops.
Description: There are many varieties of cotton, and some require less water than others. Additionally, scientist have
created alternate types that require very little. Why can't people use those varieties?
Use crops native to a desert climate
PROS No additional water
would be needed on a regular basis.
It would be easier to care for the plants.
Salinization to the land would stop.
CONS These types of crops
are not worth as much money to farmers, whereas cotton is worth quite a bit. Farmers want to earn as much as possible.
Description: There are many types of plants that grow well and naturally in a desert. Farmers should just grow what the land
would naturally allow them to grow.
Build dams to divert more river water back to the Aral Sea
PROS In a matter of
decades all the water would return.
Health of the region would greatly improve.
CONS Estimates suggest it
would cost between 30-50 billions dollars.
Some countries are less willing than others to help restore the Aral Sea.
Description: Other dams could be built on the Amu and Syr rivers, as well as other rivers in different countries, to divert water back in the Aral Sea. It is estimated that it could return entirely in
20-30 years if this were done.
Utilize international efforts for restoration
PROS The more countries
helping, the less the financial burden for individual nations.
It could create a shared sense of responsibility for the sea.
CONS There are some
countries not willing to help, for example Uzbekistan who is currently diverting much of the water for their cotton crops.
Description: If the Aral Sea is ever going to actually return, it is going to require a joint effort from many countries, particularly the
countries within the region (Kazakhstan, Uzbekistan, Turkmenistan, Tajikistan and Kyrgyzstan). Other global agencies
are helping as well such as the World Bank.
