A Fast Track Approach to Deal with the Temporal Dimension of Crop Water Footprint
Environmental Research Letters
4 July 2017
This article demonstrates the feasibility of the Fast Track (FT) approach to deal with the temporal dimension of crop water footprint and provide estimates of the temporal variability of crop water footprint (CWF). The method is tested by comparing the annual CWF country values of wheat, rice, maize and soybean obtained through the FT approach with those obtained by a detailed model accounting for the changes of yield and evapotranspiration over time.
