Global water crisis poses risk to half of world food production in next 25 years
A landmark report from the Global Commission on the Economics of Water warns that over half of the world’s food production could be at risk within 25 years due to an escalating water crisis, necessitating immediate global cooperation and sustainable management of water resources.
According to The Guardian, the report, published on October 16, highlights that currently, half of the global population already faces water scarcity, a figure expected to rise as climate change intensifies. By 2030, demand for fresh water is projected to outstrip supply by 40%, raising alarms about the sustainability of food systems worldwide.
Experts emphasize that the amount of water needed for a decent standard of living has been grossly underestimated. While common estimates suggest that individuals require 50 to 100 liters daily for health and hygiene, the report asserts that approximately 4,000 liters are necessary for adequate nutrition and a dignified life. This discrepancy underscores the critical interdependence between water availability and food security.
The report also points to the vital role of ecosystems in maintaining water supplies. Regions like China and Russia benefit from “atmospheric rivers” that transport moisture, while countries such as India and Brazil facilitate this global water cycle. The interconnectedness of these systems highlights the need for cooperative international governance.
Furthermore, harmful agricultural and industrial subsidies are identified as significant contributors to water mismanagement. These subsidies often incentivize wasteful practices, disproportionately benefiting wealthier individuals and industries while leaving vulnerable populations with limited access to clean water.
Ultimately, the commission calls for a paradigm shift in how water is perceived—recognizing it as a global common good. Without urgent action, the report warns that water-related problems could reduce global GDP by 8% by 2050, with developing nations facing even steeper declines.
