At the global level, water stress remains at a safe level of 18.2% in 2020, but this figure masks vast regional variations and indicates a 1.2% increase from 2015 to 2020. In 2020, water stress levels ranged from high in Southern Asia and Central Asia to critical in Northern Africa. The situation in Western Asia and Northern Africa is particularly concerning since it registered an 18% increase in water stress levels from 2015 to 2020.
