The Aral Sea was once the world’s fourth-largest lake, but an irrigation project drained nearly all the water. The consequences include the loss of a fishing industry, salt-laden dust affecting crops and human health, and an altered climate. A dam has increased water levels in a small part of the lake called the North Aral.

In the not so distant past, this harsh environment was actually the bed of one of the largest lakes in the world – the Aral Sea. Shorelone of the Aral Sea as seen over the years. Image: Philip Micklin (2016) For reasons both climatic and anthropogenic, the Aral Sea began receding in the 1960s.
Subsequently, after consultation with Aral — another of Vosoughi’s graduate advisors, who has studied social networks extensively — the three researchers decided to try the approach used in the new study: objectively identifying news stories as true or false, and charting their Twitter trajectories.
Water scarcity: The Aral Sea Wedged between Kazakhstan and Uzbekistan, this was once the world’s fourth-largest inland lake. But the rivers that traditionally fed it were diverted for irrigation, and climate change has intensified local water scarcity.
In Uzbekistan, for example, cotton farming used up so much water from the Aral Sea that it dried up after about 50 years. Once one of the world’s four largest lakes, the Aral Sea is now little more than desert and a few small ponds.
In Uzbekistan, a regreening programme has planted trees and shrubs across one million hectares along the Aral desert. This includes the black saxual shrub, which is highly drought resistant and can fix salt and sand, stopping it from being swept up and carried inland by sandstorms.
