Condition of Water scarcity in the Arab region.
In the Arab region , nearly 86% of the population, or nearly 362 million people, live under conditions of water scarcity or absolute scarcity . Fourteen countries in the region use more than 100% of their available freshwater resources, which strains efforts to achieve the SDG Target 6.4 that aims to reduce the number of peoplefacing water stress (UNDESA). This scarcity has increased dependency on transboundary waters, non-renewable groundwater resources and non-conventional water resources. The use of treated wastewater has been expanding in the region. More than two thirds of collected wastewater in the Arab region is safely treated at the secondary or tertiary level . In most countries of the Arabian Peninsula, treated wastewater is used for greenbelts and nature reserves, and to combat land degradation (UNESCWA, 2017)
