Why in the News?
Recently, NASA’s Earth Observatory shared an in-depth analysis of the factors contributing to the disappearance of the Aral Sea.
What are the factors responsible for disappearance of Aral Sea?
1. As per the space agency’s findings, in 1960, the Soviet Union initiated a significant water diversion project by redirecting the Syr Darya and Amu Darya rivers for irrigation purposes.
Note– The Aral Sea formed from water flowing from the Syr Darya and the Amu Darya rivers, which relied on glacial melt.
2. While the project caused the desert region surrounding the sea to flourish, it had a catastrophic effect on the Aral Sea. The waterbody began to dry up gradually and is now close to completely disappearing.
