Editor's Note: This article is the second installment in a RANE series on the geopolitical impacts of water stress. The first provides a broad overview of how unequal distribution of freshwater shapes geopolitical patterns. Water distress risks destabilizing economies across the globe, increasing the threat of cross-border migration flows while contributing to intra-regional economic divergence. A range of factors is stressing water supplies around the world, including climate change and changing weather patterns, as well as population growth, rapid urbanization, industrialization, and the use of agricultural techniques that drain groundwater. In 2020, the U.N. Food and Agriculture Organization (FAO) considered global water stress, defined as freshwater withdrawal as a proportion of freshwater resources, to be at a "safe" level of less than 19%. However, stress levels differ dramatically around the world, ranging from high in Southern Asia and Central Asia to critical in Northern Africa.
