Satellite photo of a lake in Central Asia are staggering, showing how human actions have an impact on the world’s total water supply.
Taken about 40 years ago, the photo shows the drought in several regions throughout the world caused by the human need for water continues to rise.
Shocking condition also occurs in the Aral Sea region in Central Asia.
Changes in the amount of water has reached an alarming level. In fact, last April, Sea conditions.
Aral described as ‘one of the worst environmental disasters in the world’ by the UN Secretary General, Ban Ki-Moon.
As an inland lake, Aral lies between Uzbekistan and Kazakhstan, which is the fourth largest lake in the world. Since the year 1960, this lake has lost more than half its volume. And now, 50 years later the lake was so live only about 10% of the initial observations.
Huge impact in this region due to temperature change and pollution continue to increase to dangerous levels. Damage to the lake also have an impact on the local fishing industry, where unemployment is rising and causing economic problems in the region.
Rich and fertile land around the world also experienced the same problem. Arid region and Iraq once had a lush green environment even known as the Garden of Eden. However, monitoring in 1973 and 2000, the marshes have been experiencing drought systematically since the mid-20th century.
It has destroyed agricultural land and habitat for Marsh Arabs Muslims who never persecuted by the Ba’ath party in Iraq.
Other regions that suffer are Nasse Lake, an artificial lake behind the Aswan dam on the Nile. This area was planned as part of a new agricultural industry in the region and Egypt. However, this region has experienced drought quickly.
Water has receded quickly left the ring-like appearance with a brown color in the wetlands around the lake because of drought, and water needs continue to increase sharply in this region.
Dr. Benjamin Lloyd-Hughes of the Walker Institute for Climate systems research at the University of Reading, says, “In the end the disaster that looks at the Aral Sea and the swamp is the combined effect of human activity and rising temperatures in the area.”
There is not much change in rainfall in the area, but the temperature has increased by more than one degree Celsius since 1970, which increase the losses due to evaporation.
“Pollution in the area will become worse as the water evaporates, pollutants in water become more concentrated and less diluted,” says Lloyd-Hughes again.
“Nothing will change rainfall but temperaturbisa increased to two degrees Celsius in the year 2100. This is not good but not too bad when compared to the Aral Sea and Mesopotamia.”
Global warming is a problem that occurs anywhere with a growing number of drought.
The growth of the agricultural system is not in line with world population continues to grow.
Water demand has exceeded supply so that the disaster in the Aral Sea has become inidikasi for concern about the future.
