Title

Transboundary: Basin Economic Allocation Model
Country
Kazakhstan Kyrgyzstan Tajikistan Turkmenistan Uzbekistan
Summary

Steadily shrinking for decades due to unsustainable irrigation policies, the Aral Sea is under increasing pressure, making both allocation and availability major challenges. Action has been taken and the Basin Economic Allocation Model has been developed as a long-term decision support system to facilitate putting “value on water use”. This demonstrates that economic models can be applied to assess economic value maximization of different water uses.

Lessons Learned

The water allocation can be supported by models that assess economic value maximization of different uses.
Model can explore whether it may be possible to change existing water allocation patterns in ways that enhance overall welfare in the basin.

Model facilitates assessment of the economic impact of changes to water allocation patterns on different groups of water users within the basin, including the riparian states, as well as different sectors such as irrigation and hydropower.

Model allows users to estimate the economic impact of changes to physical infrastructure such as new reservoirs and irrigation efficiency improvements.

Model facilitates application of the IWRM modeling approaches and tools in the government policy making and regional cooperation and contributes to development of resource efficient green growth strategy in the Aral Sea basin.
