It includes a biophysical component, computing the provision of freshwater, or water yield, by different parts of the landscape, and a valuation component, representing the benefits of water provisioning to people. The biophysical ... value of water withdrawals is small compared to water yields (see Sect. 4).

The average withdrawal rate, 39 mm yr−1 , was subtracted from the predicted water yields ... boundary are presumed negligible, resulting in a simple water budget based on catchment precipitation, evapotranspiration, and water yield.
