Zusammenfassung:Taking six southern Mediterranean countries as a case study, this paper addresses the water-food challenges facing water-scarce countries and the implications for the world food economy. By accounting the volume of virtual water embedded in food imports into the countries concerned, a close relationship between water endowment and food import dependence is elaborated. A projection of the cereal demand suggests an increment of 40-60 percentage points in these countries by 2020 above their 1998-99 levels, raising the aggregate volume of cereal imports to around 40 million tons. The analysis also finds that the trend of shifting from staple grain crops to higher-value cash crops was weak during the past two decades. (DSE/DÜI)
