The recent European heatwave has sparked food price fears as it destroyed an estimated €2bn worth of crops, including wheat, barley, maize, and oats. Coceral, the European cereals and oilseeds trade association, reported that the reduction of 9 million tonnes will push EU and UK harvests to their smallest since 2018. This lost production exceeds the combined grain output of Austria, Ireland, and the Netherlands, highlighting the severity of the event.
How the Heatwave Affected Key Crops
June 2023 was the hottest on record in western Europe, with temperatures exceeding 38°C in parts of France. Maize suffered during its crucial pollination phase, while wheat was damaged during the “grain fill” period when moisture is essential for yield. Tom Lancaster of the Energy and Climate Intelligence Unit (ECIU) warned that this will hit farmers’ incomes and undermine European food security.

Country-by-Country Crop Losses
France is expected to lose 3.4 million tonnes of maize, costing an estimated €891 million. Hungary follows with 2.4 million tonnes lost, and Spain with 1.4 million tonnes. These three nations account for the bulk of the €2bn damage.
| Country | Estimated Crop Loss (million tonnes) | Financial Impact (€ million) |
|---|---|---|
| France | 3.4 | 891 |
| Hungary | 2.4 | — |
| Spain | 1.4 | — |
Key Takeaways from the Heatwave’s Impact
- European grain harvest at its smallest since 2018.
- €2bn in lost revenue for grain farmers across the EU and UK.
- Climate change is driving extreme weather that threatens food production.
- Consumers may face higher bread, cereal, and livestock feed costs.
- Adaptation measures, like drought-resistant crops, are now critical.
The heatwave’s effects will ripple through the food supply chain, from farm to table. Benoît Merlo, a French farmer, noted that even a decade of adapting to hotter conditions couldn’t save his crops this year. The ECIU stresses that without rapid emission reductions, such losses will become more frequent.
FAQ
Will food prices rise because of the heatwave?
Yes, the loss of 9 million tonnes of grain is expected to push up prices for wheat, maize, and barley, which directly affects bread, cereal, and meat prices. Consumers may see higher grocery bills in the coming months.
Which crops were hit the hardest?
Maize and wheat were the most affected because the heatwave coincided with their critical growth stages—pollination for maize and grain fill for wheat. Barley and oats also suffered, but to a lesser extent.
How is climate change related to this crop loss?
Climate change increases the frequency and intensity of heatwaves. The June 2023 heatwave broke records in western Europe, and scientists link such extremes to global warming. Without mitigation, similar events will become more common.
This crisis serves as a stark reminder of the fragility of global food systems. As the ECIU’s Lancaster put it, “This will hit farmers in the pockets, reducing their income and undermining European food security.” The need for sustainable farming practices and climate-resilient crops has never been more urgent.
