The process of turning salt water into fresh water.
Sorry there is no such thing as 'desilation'.
Water desalination is the process of removing salts and other impurities from seawater or brackish water to make it suitable for consumption or agricultural use. This is typically done through methods such as reverse osmosis, distillation, or ion exchange. Desalination is important in areas facing water scarcity and can provide a sustainable source of fresh water.
Farming in northeastern Iraq is made possible by the presence of the Tigris and Euphrates rivers, which provide water for irrigation. Farmers in the region grow a variety of crops such as wheat, barley, rice, and dates using traditional flood irrigation methods. Additionally, advancements in irrigation technology, such as drip irrigation, have helped improve water efficiency and crop yields in the region.
Ground 0.9%, Salt 97%, River 2%, surfacewater 87% ^ those are the percentage of how much water we cant get too without paying we have to pay for going that deep into the ground (well for ground water) so if we run out of water (which is most likely not possible because we have pumping systems also known as desilation systems) but lets just say its alot of money (also pumping systems are also very expensive) Lake,Rivers,and sreams are the three main sources of fresh water!
