Inland sea divided between Kazakhstan and Uzbekistan, the world's fourth largest lake; former area 62,000 sq km/24,000 sq mi, but decreasing. Water from its tributaries, the Amu Darya and Syr Darya, has been diverted for irrigation and city use, and the sea is disappearing, with long-term consequences for the climate.
Between 1960 and 1990 the water level dropped 13 m/40 ft, reducing the lake to two-thirds of its original area. Between 1989 and 1991 alone, its area was cut by nearly half, from 63,800 sq km/24,626 sq mi to approximately 36,000 sq km/13,896 sq mi. This shrinkage has led to hotter, drier summers and longer, colder winters and the number of days without rain per year has increased from 30 in 1950 to 120–150 in 1990. Of the 24 fish species in the lake all 20 native species have disappeared, and winds drop 43 million metric tons of salt a year on the surrounding cropland.
In Jan 1994 the governments of five central Asian states pledged 1% of their budgets to help save the Aral Sea and improve the health of those living near.
