Sorghum hits 103,000 ha in France as maize losses near 50%

For climate professionals, the sorghum trial in Essonne is a rare on-the-ground case of anticipatory adaptation: a farmer restructuring a rotation around a crop projected to be viable decades ahead, rather than reacting after failure. With maize losses near 50% and sorghum thriving between 25C and 35C, it previews how European agriculture may re-map itself as warming accelerates.

Europe's maize harvest has been hollowed out by the summer of 2026. French producers say almost half of this year's crop is unusable after successive heatwaves and an extended drought, and in regions such as Essonne, south of Paris, that failure is forcing cereal farmers to confront a question that was once purely theoretical: what do you plant when the crop your rotation was built around can no longer tolerate the climate? For a growing number, the answer is sorghum, a hardy cereal native to sub-Saharan Africa that flourishes in temperatures between 25C and 35C and, unlike maize, hangs on through dry spells because its root system can descend up to two metres in search of moisture.

With maize losses near 50% and sorghum thriving between 25C and 35C, it previews how European agriculture may re-map itself as warming accelerates.

Eudes Coutté, a French sorghum grower tending a four-hectare patch of green and red among the yellow squares of wheat and rapeseed, embodies the shift. He settled on his farm a decade ago and calculated that a 42-year farming career would be impossible without change: 'if we don't make decisions now, we're going to hit a wall.' That led him to study African plants and, ultimately, to sorghum, which the World Wildlife Fund and the United Nations have described as a 'plant of the future' and an eco-friendly option. The timing matters: Coutté made his bet ten years before the 2026 maize collapse, a textbook case of anticipatory rather than reactive adaptation.

Sorghum is not a niche curiosity. It is the world's fifth most important cereal crop, after wheat, maize, rice and barley, widely grown across sub-Saharan Africa and parts of Asia for human consumption and, particularly in the Americas, as animal feed. France's cooler climate was once poorly suited to it, but cultivation has expanded steadily over the past 15 years, and in 2024 France became Europe's largest producer with roughly 103,000 hectares under cultivation, according to the Chamber of Agriculture. The crop's appeal is agronomic: it generally requires less water than maize, its deep roots make better use of available moisture, and it is more resistant to drought. Coutté describes the plants as resembling small maize around 80 centimetres tall, with ears of small green balls that turn red as they mature — a visual signature now appearing in the French countryside, with harvest running from September through November depending on weather.

Yet the reporting is careful not to oversell sorghum as a miracle crop. The three completely dry months this summer still affected some ears, leaving them yellowed and dried out, and the economics remain fragile. As the story states plainly, making a living from sorghum 'remains a long way off.' The value chain — seed supply, buyers, processing and market prices — is far less developed than the well-oiled maize system it would partially replace. For French farmers, the decision to switch is therefore a bet on future climate as much as on current prices, and the payoff is uncertain.
