Within that context, the GCC countries produce approximately half the world’s desalinated water; and Jordan, Palestine and Yemen are incorporating the desalination of seawater and brackish in their water strategies in order to augment their water supplies. Large-scale investments are already under way in Jordan and Yemen, and small household desalination units can be found in the Gaza Strip. However, some adverse environmental impacts are associated with desalination, including the discharge of hot and concentrated brine into coastal marine environments, the entrapment of aquatic creatures in plants intakes, and the production of carbon dioxide (CO2).
