Another option to find the optimum of environmental sustainability be evaluated regarding their suitability for more intensive cultivation, thereby potentially (partially) replacing less optimal crops. Examples of crops with comparably high economic water productivity that receive less consideration at present are tobacco, tomatoes, strawberries, cucumbers and tangerines.
Except for tobacco, these crops exhibit a comparably low consumptive water footprint (see Appendix). For a certain region
an alternative crop variety may pose an opportunity to raise both sustainability and efficiency.
