Transboundary: Basin Economic Allocation Model (BEAM); An Economic Model of Water Use Developed for the Aral Sea Basin (#432)

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.
