Great way to begin the first full week of April 2010 - a water intelligence report on one of the most strategically important regions in the world - Central Asia. In this case, 'Central Asia' means the former Soviet republics of Kazakhstan, Turkmenistan, Uzbekistan, Tajikistan, and Kyrgyzstan.
The report places a strong emphasis on the Aral Sea basin.

The report is a product of UNDP's Water Governance Facility at the Stockholm International Water Institute (SIWI).
One item jumped off page 15 - the reduction in average annual inflows to the Aral Sea over the past 30 years, due mostly to irrigation diversions from the two major rivers, the Syr Darya and Amu Darya:
Before 1960: 56 cubic kilometers/year
1961-1970: 43
1971-1980: 17
1981-1990: 4
Since one cubic kilometer is about 810,000 AF, the average annual inflows have dropped from over 45 MAF to about 3.2 MAF. It's no wonder the Aral Sea has shrunk dramatically. The graphic below is from the Aral Sea Foundation (click to enlarge):
The northernmost remnant of the sea is being 'rehabilitated' by Kazakhstan, and is apparently on its way to becoming a fishery again.
The desiccation of the Aral Sea is one of the great environmental disasters of the 20th century. Even UN Secretary General Ban Ki-moon agrees. Oh, yes - the irrigation diversions did make the Soviet Union self-sufficient in cotton.
