Note: the Prec, Peff and ET are from CROPWAT outputs, whereas the WF and rainwater use efficiency are from calculations. The average yields are either from statistical reports, or from literature collections. Abbreviations: Prec, annual precipitation; Peff, effective precipitation; ETc, crop evapotranspiration; and WF, water footprint.
