Abstract

The Middle East and North Africa (MENA) region faces unprecedented water scarcity, driven by arid conditions, limited freshwater resources, and rising demand due to growing populations. This review examines the potential of unconventional water resources including treated wastewater, agricultural drainage water, and desalination as sustainable solutions to mitigate water stress in Egypt, Morocco, Tunisia, Lebanon, and Jordan. With per capita water availability in many MENA nations expected to drop below 500 m³/year by 2030 and agriculture accounting for over 80% of water use, the region’s food security and economic stability are at risk. Climate change further exacerbates these challenges through prolonged droughts and unpredictable rainfall. This paper analyzes country-specific approaches, such as Egypt’s large-scale drainage water reuse, Morocco’s climate adaptation strategies, Tunisia’s policy-driven water management, and the acute water crises in Lebanon, and Jordan. Key findings emphasize the importance of integrated water resource management, advanced treatment technologies, and cross-border collaboration to optimize unconventional water use. By evaluating current practices and future opportunities, this study highlights how MENA countries can enhance water security, sustain agricultural output, and reduce the socio-economic impacts of water scarcity in an increasingly climate-vulnerable region.
