Global Water Crisis Leaves Half of World Food Production at Risk in Next 25 Years (theguardian.com) 124
More than half the world's food production will be at risk of failure within the next 25 years as a rapidly accelerating water crisis grips the planet, unless urgent action is taken to conserve water resources and end the destruction of the ecosystems on which our fresh water depends, experts have warned in a landmark review. From a report: Half the world's population already faces water scarcity, and that number is set to rise as the climate crisis worsens, according to a report from the Global Commission on the Economics of Water published on Thursday.
Demand for fresh water will outstrip supply by 40% by the end of the decade, because the world's water systems are being put under "unprecedented stress," the report found. The commission found that governments and experts have vastly underestimated the amount of water needed for people to have decent lives. While 50 to 100 litres a day are required for each person's health and hygiene, in fact people require about 4,000 litres a day in order to have adequate nutrition and a dignified life. For most regions, that volume cannot be achieved locally, so people are dependent on trade -- in food, clothing and consumer goods -- to meet their needs.
Some countries benefit more than others from "green water," which is soil moisture that is necessary for food production, as opposed to "blue water" from rivers and lakes. The report found that water moves around the world in "atmospheric rivers" which transport moisture from one region to another.
