Conclusions
The Aral Sea and surrounding region has suffered large scale negative environmental change accompanied by major economic losses and human suffering over the past 4 decades owing to development of massive irrigation works. Soviet planners and engineers in 1950s, 1960s and 1970s underestimated both the range and severity of these consequences. They were confident that the socio-economic benefits of irrigation development outweigh any harm that might result.
What lesson can be learnt from the Aral Sea experience?
1) Once a large hydrological system such as the Aral Sea basin is in the throes of radical change, it is very difficult, costly and requires a lengthy period to reverse the process (i. e. it is much easier to create such problems than to rectify them).
2) Simplistic and, at first glance, appealing proposals to correct complex water management problems in the Aral Sea basin quickly (e. g. through rapid and massive cuts in irrigation to free water for the Aral Sea) should be approached with caution as they may so disrupt the economy as to cause its collapse.
