  Aral Sea - Wikipedia, the free encyclopedia
The Aral Sea (Kazakh: Арал Теңізі, Uzbek: Orol dengizi) is a landlocked endorheic sea in Central Asia; it lies between Kazakhstan in the north and Karakalpakstan, an autonomous region of Uzbekistan, in the south.
The Aral Sea is heavily polluted, largely as the result of weapons testing, industrial projects, and fertilizer runoff before and after the breakup of the Soviet Union.
In 1960, the Aral Sea was the world's fourth-largest lake, with an area of approximately 68,000 km² and a volume of 1100 km³; by 1998, it had dropped to 28,687 km², and eighth-largest.

The sea is, as a result, now greatly reduced, mainly occupying three basins in the central, western, and northern sections of its lakebed.
The United Nations has estimated that the sea will essentially disappear by 2020 if nothing is done to reverse its decline, but in 2003 construction began on a dike to enclose the smaller northern section, in an attempt to revive at least that.

The sea bed, formerly referred to as a so-called "fresh water maker" of vast water collecting basin at the expense of rich sea hydrobiocenose activity, is an artificial anthropogenous volcano, throwing tremendous masses of salt and finely-dispersed dust into the atmosphere.
That is why traces of pesticides from the Aral region were found in the blood of penguins in the Antarctic, and typical Aral dust has been found on Greenland's glaciers, in Norway's forests, and Byelorussia's fields, all situated thousands of kilometers away from Central Asia.

 Desiccation of the Aral Sea: A Water Management Disaster in the Soviet Union
The Aral Sea is a huge, shallow, saline body of water located in the deserts of the south-central Soviet Union (Figs.
As in the past, the cause of the modern recession of the Aral is a marked diminution of inflow from the Syr Dar'ya and Amu Dar'ya, the sea's sole sources of surface water inflow, that has increasingly shifted the water balance toward the negative side (Table 1).
During planning for a major expansion of irrigation in the Aral Sea basin, conducted in the 1950s and 1960s, it was predicted that this would reduce inflow to the sea and substantially reduce its size.

 ARAL SEA
Humans have made use of the waters of the Aral basin for thousands of years, borrowing from its two major rivers: the Amu Darya, which flows into the Aral Sea from the south; and the Syr Darya, which reaches the sea at its north end.
The sea could be stabilized with improvements in the efficiency of irrigation, but would remain incapable of supporting most fauna, and the current problems of pollution and lost habitat would go unaddressed.
The shrinking of the sea has exposed almost 30,000 square kilometers of lake bed, which is so filled with salts and chemicals that it is toxic to plants.

A three-fold increase in reflected solar radiation in the Aral area due to a sevenfold rise in the albedo of the area previously occupied by the Aral Sea has contributed to an increase in the continentality of the climate (Kondratyev, Grigoryev, and Zhvalev 1986).
A specific peculiarity of the Aral basin is the increase in river-water mineralization owing to the discharge of drainage waters from irrigated massifs.

Given the region's arid climate, irrigation was imperative, and the Aral Sea and its tributaries seemed a limitless source of water.
Another proposal is to restore the Northern Sea to a level of 38m to 40 m above sea level, requiring an inflow of at least 6-8 cubic km in that part of the Aral Sea for the next five years.
One important measure for the future would be to consider the Aral Sea and the two deltas as a "sixth state" with a water allocation from the five Central Asian republics.

The drying up of the Aral Sea – once the world's fourth largest inland water body, covering an area the size of Belgium and the Netherlands combined – has long been one of the biggest man-made catastrophes in history, bringing poverty, disease and death to the 3.5 million people living around it.
The Soviet Union, deciding that the Aral Sea was 'nature's error,' diverted almost their entire flow to grow cotton in the surrounding desert.
Every year some 70 million tons of dust from the dried-out sea bed – contaminated by salt and pesticides such as DDT long ago washed there off farmland – is blown over the surrounding land.

Moreover, it lies on higher ground north of the larger Aral sea bottom, and the fishermen in the region are building a dam on the former seabed to keep the sea from overflowing.

 EO Newsroom: New Images - Aral Sea
Once the fourth largest lake on Earth, the Aral Sea has shrunk dramatically over the past few decades as the primary rivers that fed the Sea have been diverted and tapped nearly dry for cotton farming and other agriculture.
The southern part of the Sea was fed by the Amurdar'ya and the northern part was fed by the Syrdar'ya, forming a large inland lake that moderated the region’s continental climate and supported a productive fishing industry.
The northern Small Aral Sea will be allowed to refill from the inflow of the Syrdar'ya, and though it is never expected to regain its former extent, planners think that it will refill enough to support a robust fishing again.
