The MENA region faces a critical water crisis driven by natural aridity, climate change, and sociopolitical instability. With just 1–2% of global freshwater resources yet supporting 6% of the global population, a severe supply-demand gap threatens regional sustainability. Predicted temperature rises of 1.5–2 °C by 2025 and up to 4 °C by 2050 intensify water scarcity, desertification, and agricultural stress, as farming consumes 80% of the region’s water. Unsustainable practices in oil-rich nations, reliance on deep aquifer depletion, and desalination contribute to environmental pressures. Conflicts over shared water sources, like the Nile, underline geopolitical tensions. Rapid population growth exacerbates resource constraints, compelling nations like Jordan and Sudan to allocate significant GDP portions to water access, while water weaponization in Libya highlights its strategic importance. Efforts to mitigate these challenges vary across the MENA region. Israel and the Gulf states use desalination, while Morocco improves groundwater management, and Jordan expands wastewater recycling. However, desalination faces sustainability concerns, notably high energy use and brine discharge impacts. Advancements have reduced desalination energy needs by 30%, and Veolia’s ecological measures have lessened environmental damage. Renewable energy-powered desalination facilities, such as those in the UAE, reflect a shift toward sustainable practices. Addressing this crisis requires regional cooperation, enhanced irrigation, improved water policies, public awareness, and technical innovations. Collaborative approaches can build resilience and long-term adaptation to secure water resources in the MENA region amidst a rapidly changing climate and sociopolitical landscape.
