Dr. Al-Qusaibi went on to remark that water is not only a national but a global issue. Saudi Arabia, he said, ranks fourth in the world in average water use per citizen, after the United States, the United Arab Emirates, and Canada, with a daily 43 liters per capita use of water. Only 10 percent of the water consumption in the Kingdom, however, is for household and commercial use. The remaining 90 percent is for agriculture: for example, each liter of milk produced in Saudi Arabia requires 1,000 liters of water.
