The best way to control water demand and maintain its utilization is to manage water resources. Virtual water trading is one of the most crucial demand management technologies. Since potatoes and onions are essential vegetables that Egypt exports, the research concentrated on their production. The fact that the amount exported varies and is unstable in the importing markets, despite the significance of potato and onion crops as export products and the scarcity of water resources, represents the research problem. Studying the amount and value of the virtual water lost and gained by their Egyptian exports is therefore essential. Estimating the virtual water and water is the primary goal of the study.
The amount of virtual water exported and the internal water footprint averaged around 102.07 million m³ and 100.87 million m³, respectively, according to a study calculating the water footprint of potato and onion crops. - The amount of virtual water exported and the export price of virtual water were the two most important independent factors influencing the value of virtual water exported for the potato crop during the period (2010–2022), according to the regression analysis of the factors determining the value of virtual water exported for potato and onion crops in Egypt. Additionally, it was discovered that the amount of virtual water exported and the export price of potato crops are directly correlated with the value of virtual water exported.
