The Aral Sea and the surrounding regions are experiencing extensive environmental degradation with major economic consequences in the five republics that share the basin — Kazakhstan, Uzbekistan, Kirghizia, Tajikistan and Turkmenistan. The area of the Aral Sea has been reduced by more than 40% and its volume by over 65% in 30 years. Total river flow into the Sea has dropped from 40 km3 in 1960 to less than 5 km3 in 1985. The salt content has increased from 10 g/l before 1960 to 28 g/l in 1989 and to 35 g/l in 1991.
