Toward a Circular Economy in the MENA Region: Insights from the Water-Food Nexus

Abstract

The water-food nexus in the Middle East and Northern African (MENA) region is characterized by resource depletion, import dependence and environmental degradation. This contribution proposes that consumption awareness and resource circularity can be seen as a pathway to alleviate environmental problems and achieve long-term supply security in the water and food sectors. The chapter introduces wastewater recycling as a salient and highly relevant development in the MENA region. Current directions in using treated wastewater are analyzed. Furthermore, forerunner countries from different MENA sub-regions are briefly introduced with the focus on the particular characteristics and policy challenges in each of presented cases of wastewater reuse. Furthermore, crosscutting issues are presented. These include the need for addressing the large consumption footprints in MENA countries, the existence of distorting subsidies for agricultural water, the lack of communities' participation, the inadequacy of existing strategies and the suboptimal coordination mechanisms between water and food sectors. We suggest at the end of the paper some recommendations to policy makers in the region.
