A new report from the Global Commission on the Economics of Water warns that over half of the world’s food production could face significant risk within the next 25 years due to a rapidly worsening water crisis.
Experts emphasize that without immediate action to conserve water and protect ecosystems vital for freshwater supplies, the situation will continue to deteriorate.
Currently, approximately half the global population already suffers from water scarcity, a number expected to increase as climate change intensifies.
The report highlights that by the end of the decade, demand for fresh water will exceed supply by 40%, as current water systems experience unprecedented stress.
The commission points out a critical miscalculation: while a person needs 50 to 100 liters of water daily for health and hygiene, around 4,000 liters are necessary for adequate nutrition and a dignified life.
Most regions cannot meet this requirement locally, relying heavily on food and goods trade.
Moreover, the report illustrates the significant role of “green water,” the moisture in soil essential for food production, and “blue water” from lakes and rivers.
Water transfers globally via “atmospheric rivers,” impacting food security and trade relationships.
For instance, countries like China and Russia benefit from these systems, while nations like India and Brazil serve as major exporters.
To tackle the crisis, the report urges governments to enhance cooperation in water resource management.
It also calls for a re-evaluation of water subsidies, redirecting funds towards efficient and equitable water use, particularly for vulnerable populations.
The findings stress the necessity of viewing water as a global common good, advocating for sustainable practices and increased access to finance for developing countries to improve their water systems and protect natural ecosystems.
