The Aral Sea was, until comparatively recently, the fourth largest inland body of water in the world. Its basin covers 1.8 million km 2 , primarily in what used to be the Soviet Union, and what is now the independent republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The environmental problems of the Aral Sea basin are among the worst in the world. Water diversions, agricultural practices, and industrial waste have resulted in a disappearing sea, salinization, and organic and inorganic pollution. The problems of the Aral, which previously had been an internal issue of the Soviet Union, became international problems in 1991. The five new major riparians- Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan-have been struggling since that time to help stabilize, and eventually to rehabilitate, the watershed.[1]

By 1990, the sea had split into two distinct bodies, the Large Aral in the south and the Small Aral to the North [2] Restoration efforts in the Small Aral have increased water quantity and quality and improved fish stocks. However, the Small Aral does not resemble the Aral Sea of decades past. [2]
