Resource / New Nature study published shows droughts and heatwaves cause 10% drop in annual crop harvests

Over the past five decades, hundreds of droughts and heatwaves have struck countries across the world. A new study finds that these events caused an average annual drop in national crop production of around 10%.

The cumulative global losses of these hot and dry extremes amount to 3bn tonnes of cereal crops, the study says – equivalent to three times the global maize harvest last year.

The findings suggest that heatwaves and drought events substantially damage crop production across the globe.
