Water Risk on the Rise
Twenty percent of global GDP already is produced in water-scarce areas. In the absence of more sustainable water management, the share could rise to 45% by 2050, placing a significant portion of global economic output at risk.
WASHINGTON, DC – Water is never far from the news these days. This summer, northern India experienced one of its heaviest monsoon seasons in 80 years, leaving more than 800 people dead and forcing another 100,000 from their homes. Meanwhile, Central Europe faced its worst flooding in decades after heavy rains swelled major rivers like the Elbe and the Danube. In the United States, nearly half the country continues to suffer from drought, while heavy rainfall has broken records in the Northeast, devastated crops in the South, and now is inundating Colorado.
Businesses are starting to wake up to the mounting risks that water – whether in overabundance or scarcity – can pose to their operations and bottom line. At the World Economic Forum in Davos this year, experts named water risk as one of the top four risks facing business in the twenty-first century. Similarly, 53% of companies surveyed by the Carbon Disclosure Project reported that water risks are already taking a toll, owing to property damage, higher prices, poor water quality, business interruptions, and supply-chain disruptions.
The costs are mounting. Deutsche Bank Securities estimates that the recent US drought, which affected nearly two-thirds of the country’s lower 48 states, will reduce GDP growth by approximately one percentage point. Climate change, population growth, and other factors are driving up the risks. Twenty percent of global GDP already is produced in water-scarce areas. According to the International Food Policy Research Institute (IFPRI), in the absence of more sustainable water management, the share could rise to 45% by 2050, placing a significant portion of global economic output at risk.
