Human activity accounts for 70% of the Caspian Sea's shrinking water levels

Human activity accounts for 70% of the Caspian Sea's shrinking water levelsA synthesis of satellite and ground-based observations has identified a direct correlation between the drastic retreat of the Caspian Sea and the systematic reduction of river inflow from bordering nations.

The Volga Factor and Systemic ExtractionThe research identifies the Volga River as the critical variable in the sea's water balance, as it provides nearly 80% of the Caspian's total inflow. Major hydroelectric dams and expansive agricultural infrastructure divert vast quantities of water before it reaches the sea. Environmental and Socio-Economic DecayThe study draws parallels between the Caspian and the catastrophic collapses of the Aral Sea and Lake Urmia.
