Assessing the economic impact of redistributing water within a catchment: a case study of the Musi Catchment in the Krishna Basin in India por Davidson, B., Hellegers, Petra J.G.J., Samad, Madar

“…Thus, the individual values of water used to produce different crops, grown over two different seasons and over five very different regions within a catchment, were determined. This is a significant improvement over previous attempts, where a single value of water in a catchment was derived regardless of what it is used for, when it was used and where it used in the catchment. …”
