Fig. 6: Future scenarios.
From: Past and future trends of Egypt’s water consumption and its sources
a Additional Virtual Water Demand (km3) [blue line] and Annual Increase Rate (km3) [black dotted line] for a nominal growth scenario (1.7% population growth, 2.3% GDP per capita growth) versus 2017 levels. Light blue shading represents the increased municipal water demand. Gray shading represents the additional virtual water imports in a 0% GDP growth, 1.7% population growth scenario. b Historical hindcast of total water use paired with the nominal projections of total water needed in panel a. The blue dotted line shows the total hindcasted water use, including efficiency scaled total agricultural demand, municipal use and industrial use, and reuse. This is compared to the sum of historical virtual water imports [blue shading] and the total Nile use estimate [red dashed line] and is shown as the solid blue line. Future projections are divided between in-country consumption [red dashed line] and increased virtual water demand [area between red dashed line and blue dashed line]. Future Projected Total Water Demand is shown by blue dashed line. Red squares mark total Nile use estimate for 1995, 2000, 2012, and 2017.
