Water crisis driven by climate change threatens global food production
The world’s supplies of fresh water can no longer be counted on due to a shift in rainfall patterns caused by climate change, a major report has warned. It's calling for global cooperation to address a problem that could put more than half of the world’s food production at risk by 2050.
Climate change, destructive land use and mismanagement of supplies has put the global water cycle under "unprecedented stress", the Global Commission on the Economics of Water (GCEW) warned in a report published Thursday.
"Nearly three billion people and more than half of the world's food production are now in areas where total water storage is projected to decline," said the GCEW, a two-year research initiative set up by the Netherlands in 2022.
Densely populated regions are especially vulnerable to freshwater shortages, it said, including northwestern India, northeastern China and southern and eastern Europe.
Agriculture is impacted, with global cereal production falling by as much 23 percent if current trends continue.
