New Study Highlights Rising Climate Risks to Global Wheat Yields
IN · Published Oct 15, 2026
• A recent study published in the journal Nature Food has revealed that current climate models significantly underestimate the impact of combined heatwaves and droughts on global wheat yields. Conducted by researchers from Southwest University, Beijing Normal University, the Chinese Academy of Sciences, and NASA’s Goddard Institute for Space Studies, the study utilised an advanced crop model to analyse data from 1981 to
• The findings indicate that droughts have reduced global wheat yields by 9.7%, heatwaves by 5.8%, and combined heatwave-drought events by 13.3%. These figures are notably higher than previous estimates. The study also found that while irrigation remains a key adaptation tool, its effectiveness has diminished over time due to the increasing frequency and severity of climate events.

Impact & Risks

The study underscores the growing vulnerability of global wheat production to climate change, with significant implications for food security, agricultural planning, and economic stability. Regions heavily reliant on wheat, including India, may face increased risks of yield losses, potentially leading to higher food prices and supply chain disruptions. The weakening effectiveness of irrigation as a mitigation strategy further exacerbates the challenge, particularly for countries with large rain-fed agricultural areas. The findings call for urgent advancements in climate-resilient agricultural practices and policies to address these escalating risks.
