What makes fishing difficult on the Aral Sea?
Not only did the Aral Sea become smaller, evaporation also triggered salinity, causing the death of almost all fish. In order to contain the salinity, the extraction of ground water was increased, decreasing the level of aquifers from 53 to 36 meters.
What is an effect of the salinization process in the Aral Sea region?
Among the environmental problems of the entire Aral Sea basin caused by large-scale irrigation, the increasing salinization of irrigated land and water is the biggest one. Currently, over 70% of the irrigated land in Karakalpakstan is affected by salinity, and problems are worsening.
What happened to the fish in the Aral Sea?
As decreasing water flow into the sea caused a rise in salinity, the abundant freshwater fish species began to die out. By the 1980s, the fishing industry in the Aralsk district—once a robust source of employment for the region—was wiped out, forcing a mass migration of people.
How did salinization affect the fish in the Aral Sea?
how did salinization affected the fish in the Aral Sea? The fishing industry in areas around the aral sea closed, it disappeared. how were peoples health affected? People no longer had fresh drinking water and as a result many people had liver and stomach problems.
Can Aral Sea be saved?
There is no work under way to restore the southern region. It has always looked like a lost cause. So Aladin says it will keep shrinking and getting saltier until only brine shrimp are left. Using less water to irrigate crops could restore the entire Aral Sea, says Micklin.
Does anything live in the Aral Sea?
“Once the world’s fourth-largest freshwater lake … the Aral Sea became the victim of the Soviet Union’s agricultural policies in the 1950s. Water from its two river sources—the Amu Darya and Syr Darya—was intentionally diverted for cotton cultivation.” Today, the Aral Sea does not exist.
How are officials trying to fix the Aral Sea?
In the end, the economic infrastructure around the water system has been partially restored. Fourth, the countries in the region began discussions addressing trans-boundary water issues, improving water management, investing in water-saving technologies, and upgrading networks of canals, dams and reservoirs.
What are the effects of the Aral Sea?
The shrinking Aral Sea has also had a noticeable affect on the region’s climate. The growing season there is now shorter, causing many farmers to switch from cotton to rice, which demands even more diverted water. A secondary effect of the reduction in the Aral Sea’s overall size is the rapid exposure of the lake bed.
What happened to the Aral Sea and why?
Formerly the fourth largest lake in the world with an area of 68,000 km2 (26,300 sq mi), the Aral Sea began shrinking in the 1960s after the rivers that fed it were diverted by Soviet irrigation projects.
Are there any fish in the Aral Sea?
Once the fourth-largest freshwater lake in the world, the Aral Sea today is a tenth of its original size. Water levels dropped and the once abundant populations of bream, carp and other freshwater fish dwindled with them. Today, the sea is a 10th of its original size and has almost split in two.
Why is the Aral Sea dying?
Once the fourth largest lake in the world, Central Asia’s shrinking Aral Sea has reached a new low, thanks to decades-old water diversions for irrigation and a more recent drought. Satellite imagery released this week by NASA shows that the eastern basin of the freshwater body is now completely dry.
How much of the Aral Sea is left?
With no other major source of water, the Aral Sea has been evaporating and shrinking ever since. After 50 years, the lake’s area is 25 percent of its original size and it holds just 10 percent of its original volume of water.
Is the Aral Sea polluted?
According to NASA, “although irrigation made the desert bloom, it devastated the Aral Sea. As the lake dried up, fisheries and the communities that depended on them collapsed. The increasingly salty water became polluted with fertilizer and pesticides. Today, the salt dunes in the area were 15 meters under sea water.
What were the impacts of the Aral Sea drying up?
As a result, the areas’s inhabitants have suffered health problems at unusually high rates—from throat cancers to anemia and kidney diseases—and infant mortality in the region has been among the highest in the world. A plume of dust blowing southeastward from the dry seabed of the southern portion of the Aral Sea.
What animals live in the Aral Sea?
Two dozen species thrived in its waters, including caviar-rich sturgeon, pike perch, and silver carp, known locally as fat tongue. The sea spread over more than 26,000 square miles, and ships could travel 250 miles from the northern port of Aralsk, in Kazakhstan, to the southern harbor of Muynak in Uzbekistan.
