Extreme Heat Threatens Global Food Systems, UN Warns
A new report from the Food and Agriculture Organization and the World Meteorological Organization highlights a growing global concern: extreme heat is pushing food systems to the brink. Rising temperatures are already disrupting agricultural productivity, with farmers in many regions facing unsafe working conditions for much of the year.
The report outlines how heat stress is impacting both crops and livestock. Staple crops such as wheat and maize are experiencing declining yields as temperatures exceed critical thresholds, while livestock face increased mortality rates and reduced productivity. Ocean ecosystems are also under pressure, as rising sea temperatures lower oxygen levels and threaten fish populations.
Experts warn that without urgent adaptation measures, these challenges could intensify food insecurity and economic instability, particularly in already vulnerable regions across Asia, Africa and Latin America. Strengthening early warning systems, supporting farmers with climate-resilient tools, and transitioning to more sustainable agricultural practices are seen as essential steps.
The findings reinforce the need for coordinated global action to address climate change and protect food security for billions of people worldwide.
