| Abstract | ||||
| The substance of worldwide water scarcity is the geographic and temporal inconsistency among freshwater demand ,water resource availability and the un-efficient use of water resources. Water footprint (WFP) and economic water productivity are considered a solution to global water stress and water scarcity. This study aims to develop a tool of the assessment of the economic water productivity (Eco-WP) and evaluate different methods of water productivity (WP) and their relationship with WFP . The WFP and Eco-WP were estimated in year 2017 for the major crops in Egypt. The results showed that there were two analyzes for Eco-WP: first, analysis per crop, the average of Crop Water Productivity was taken for each crop to compare crop's water productivity for overall Egypt. Second, analysis per governorate, the average governorate Water Productivity for all crops planted in this governorate. Also, the relationship between Eco-WP and WFP was a reverse relationship (power equation). For the first analysis, the most suitable method to judge Eco-WP was the Energy Price Method with 0.98 (R2). However, the appropriate method to assess Eco-WP was the net revenue method with 0.56 (R2). | ||||
