Stable and abundant water supplies are becoming increasingly difficult to come by on a warming planet with a growing population. And according to new data, 37 countries in the world already face "extremely high" levels of water stress. Water stress indices are commonly used to visualize water resources vulnerability on a global scale. Since the introduction of the Falkenmark Indicator in 1989, a multitude of alternative water stress indices have emerged, each with their own unique set of assumptions and goals.1 For With the existing climate change scenario, almost half the world's population will be living in areas of high water stress by 2030, including between 75 million and 250 million people in Africa. In addition, water scarcity in some arid and semi-arid places will displace between 24 million and 700 million people. The consequences of such stress are local, national, transboundary, regional, and global in today’s interconnected and rapidly changing world. Consequences will be disproportionately felt by the poorest and most vulnerable. Climate change expresses itself through water. 9 out of 10 natural disasters are water-related.
Level of water stress: freshwater withdrawal as a proportion of available freshwater resources from The World Bank: Data.
America’s Water Stress Index. To properly diagnose water risk, Columbia Water Center researchers examined both existing demand and variations in renewable water supply at appropriate spatial resolution and unit. A metric that can inform the potential severity of a shortage is the accumulated deficit between demand and supply at a location. Water Stress “Water stress” refers to the ability, or lack thereof, to meet human and ecological demand for fresh water. Compared to scarcity, “water stress” is a more inclusive and broader concept.
