Using the concept of virtual water introduced by Allan 1994 and developed by Hoekstra and Hung (2002), we estimate virtual water trade for 20 crops of Saudi Arabia during 2000-2016. Our result shows the average virtual water trade was 12.6 billion m3/year. Saudi had net virtual water imports, with the most significant virtual water import for cereals & alfalfa and vegetable; and there is a virtual water export of fruit. Saudi virtual water trade reduced pressure on water resources by 54%. Distance plays a role in Saudi virtual water export; we found that more than 90% of exports go to neighboring countries, including 45% to GCC countries. On the other hand, more than 40% of virtual water imports came from Asia.
