The authors would like to make the following corrections to the published paper [1].
The equation for the blue water footprint (Equation (6)) is the same as the equation for the green water footprint (Equation (3)).
According to the water footprint methodology [1], the blue water footprint of crops represents the amount of blue water provided to crops by irrigation. The irrigation requirement is zero if an effective rainfall (Peff) is larger than the crop water requirement. The crop water requirement is represented by the total crop evapotranspiration, ETc. Therefore, Equation (6) could be as follows:
ETblue = max(0, ETc–Peff)
The authors assume that this was just a typographical error, as Figure 6 shows different values for the blue and green water footprints.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
