Summary
The Aral Sea was, until comparatively recently, the fourth largest inland body of water in the world. Its basin covers 1.8 million km2 , primarily in what used to be the Soviet Union, and what is now the independent republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. Small portions of the basin headwaters are also located in Afghanistan, Iran, and China. The major sources of the Sea, the Amu Darya and the Syr Darya, are fed from glacial meltwater from the high mountain ranges of the Pamir and Tien Shan in Tajikistan and Kyrgyzstan. 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. In February 1992, the five republics negotiated an agreement to coordinate policies on their transboundary waters. Subsequent agreements in the 1990s and in 2002 have updated policies and reorganized transboundary water management institutions. As a result the atmosphere gained from the Heads of State of the Aral Sea Basin nations and their recognition that the benefits of cooperation are much higher than that of competition, interstate water management has been coupled with broader economic agreements including trade of hydroelectric energy and fossil fuel to promote regional goals.

The Problem
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.
Background
The Aral Sea was, until comparatively recently, the fourth largest inland body of water in the world. Its basin covers 1.8 million km2, primarily in what used to be the Soviet Union, and what is now the independent republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. Small portions of the basin headwaters are also located in Afghanistan, Iran, and China. The major sources of the Sea, the Amu Darya and the Syr Darya, are fed from glacial meltwater from the high mountain ranges of the Pamir and Tien Shan in Tajikistan and Kyrgyzstan.
Irrigation in the fertile lands between the Amu Darya and the Syr Darya dates back millennia, although the Sea itself remained in relative equilibrium until the early 1960s. At that time, the central planning authority of the Soviet Union devised the "Aral Sea plan" to transform the region into the cotton belt of the USSR. Vast irrigation projects were undertaken in subsequent years, with irrigated area doubling between 1960 and 1990.[2]
Such intensive cotton monoculture has resulted in extreme environmental degradation. Pesticide use and salinization, along with the region's industrial pollution, have decreased water quality, resulting in high rates of disease and infant mortality. Water diversions, sometimes totaling more than the natural flow of the rivers, have reduced the Amu Darya and the Syr Darya to relative trickles-the Sea itself has lost three-quarters of its volume and half its surface area, and salinity has tripled, all since 1960. The exposed sea beds are thick with salts and agricultural chemical residue, which are carried aloft by the winds as far as the Atlantic and Pacific Oceans.
Attempts at Conflict Management
The intensive problems of the Aral basin were internationalized with the breakup of the Soviet Union. Prior to 1988, both use and conservation of natural resources often fell under the jurisdiction of the same Soviet agency, but each often acted as powerful independent entities. In January 1988, a state committee for the protection of nature was formed, elevated as the Ministry for Natural Resources and Environmental Protection in 1990. The Ministry, in collaboration with the Republics, had authority over all aspects of the environment and the use of natural resources. This centralization came to an end with the collapse of the Soviet Union in 1991. Shortly after, the Interstate Coordination Water Commission (ICWC) was formed by the newly independent states to fill the regional planning void that accompanied the loss of Soviet central control.
In February 1992, the five republics negotiated an agreement to coordinate policies on their transboundary waters. Subsequent agreements in the 1990s and in 2002 have updated policies and reorganized transboundary water management institutions.
