Abstract

This research aimed to estimate the total water footprint of the most important Egyptian export crops, as well as the internal and external water footprints of the study crops. It was shown through the results of the research regarding the potato crop that the percentage of dependence on external water imports reached its lowest level in 2012 at about 2.6%, and it also reached its maximum level.
In 2015 year, it was about 11.4% the average percentage of dependence on external water imports for potatoes was about 7.6% as an average for the study period. The standard deviation was about 1.41 and the coefficient of variation was about 18.6%. The percentage of dependence on local water resources was also about 11.4%. Its lowest limit was about 88.4% in 2005, and its maximum in 2009 was about 98.1%. The average dependence on water resources was about 92.4% as an average for the study period. As for the grape crop, it was found that the percentage of dependence on external water imports for grapes reached its lowest limit in 2018 was about 0.25%, and its maximum in 2004 was about 7%. The average percentage of dependence on external water imports for grapes was about 2.4%, while the percentage of dependence on local water resources reached its lowest limit in 2004 at about 93%, and reached its maximum in 2018 at about 99.75%, and the average dependence on water resources reached about 97.6% as an average for the period of the study.
