A Proposal of a New Supply System of Fresh Water for Afforestation of the Desert in the Middle East

Many countries that import energy resources, such as crude oil and liquefied natural gas, from the Middle East have a lot of domestic wastewater, most of which is discharged into rivers and the ocean after being purified by a high-class treatment. Meanwhile many Middle Eastern oil-producing countries that export energy resources have vast deserts and a large demand for the fresh water needed for irrigation. Meanwhile, large crude oil carriers and LNG tankers that are used to transport energy resources need to load and discharge a large amount of ballast water to safely voyage across the ocean. However, that ballast water pollutes oceans on a global scale by diffusing foreign aquatic microbes. This paper suggest a new system in which large tankers load highly purified recycled water as ballast water, voyage to Middle East, and discharge it for use in irrigating the desert there. Thus the system will provide a solution to some of the environmental issues that these oceanic ships cause and contribute to preserving the global environment.
