Water risk maps help governments and nations understand and plan around falling water supplies in certain areas. As you can see in the map above, the darker shades represent the over-exploited areas and we can see where the water stress indicators are in the major basins.
Risk of water shortage is becoming a bigger topic, especially among investors globally who now want to know how much exposure a particular company may have. Historically it has been very difficult to work out where the low or high risk areas have been, newer tools are being produced, the most promising of it’s kind being the Aqueduct water risk map.
“Water is an incredibly important part of both the manufacture and use of P&G brands,” says Len Sauers, the company’s vice president of global sustainability. “We want to make sure all of our operations are in locations that are best for both our business and the environment, so partnering to understand water scarcity and related issues throughout the world is critical.” 
But it’s not just companies and investors that should pay attention to water risk; governments need to as well, as water stress can have serious national and international consequences.
