Abstract: The best available high-resolution precipitation, GDP, available freshwater and withdrawal data sets are used in a combined global analysis of physical and economic water scarcity at 50 km resolution. We find that approximately 40.7 million people are living in areas with concurrent severe economic and water-scarcity constraints. These areas are mostly in semi-arid parts of Sub-Saharan Africa, the Middle East and Central Asia.
