Successive intense heatwaves and an increasingly severe, continent-wide drought have left many of Europe’s farmers in an “unprecedented” crisis, with vegetable and grain growers in particular warning of “catastrophic” harvests. French vegetable production is down by “a very significant extent” compared with previous years, French growers have said, with shortfalls put at 25% for courgettes, 35% for lettuces, 40% for peas, 60% for broccoli and 50% to 100% for artichokes. Accelerated, human-caused global heating and a supersized El Niño have scorched fields across Europe this summer, with plant development prevented by temperatures routinely exceeding 30C and often 35C, almost no rainfall, and hot winds.
Part of the fall is due to farmers’ switching to other crops, such as sunflowers, the ministry said, but it also reflects the impact of this summer’s vicious heatwaves, which have battered the crucial crop during critical stages of its growth cycle. That is likely to cause big problems for livestock farmers. With dairy cows typically starting to suffer from heat stress above 25C, many producers have already reported milk yields down by 10%-15%.
Most are now also concerned about winter feed. Agreste, the agriculture ministry’s statistics service, said last week that production of hay for winter cattle forage was running about 30% lower than the 1989-2018 average, a shortfall that “is worsening and is now affecting a growing numbers of regions”. Egg production, too, has been hit by a catastrophic mortality rate in poultry houses, particularly during the June heatwave.
According to France’s national egg promotion board, output has is about 1m eggs a day lower than the norm. In Italy, about 60% of farmland across the country is now affected by drought ranging from mild to severe, according to data published earlier this month by Coldiretti, the country’s largest farmers’ organisation. Crop yields, especially for corn, rice and soya beans as well as vegetables and fruit, have been badly hit, and milk production has fallen by 20%.
The overall cost to the sector, including damage caused by wildfires and heavy storms, is put at more than €3bn. The drought is particularly acute in the Po valley, a huge geographical area straddling four northern regions, the backbone of Italian agriculture and home to about 80% of the Italian rice production, due to severe depletion of the country’s longest river. Italy is Europe’s largest rice producer, with about 235,000 hectares (580,000 acres) planted in 2025.
This year, however, the severe drought has forced growers to adopt an unprecedented response to save the season, irrigating crops only on alternate weeks. In Spain, cereal harvests are 35% below the previous year in Castilla y León, 49% in the Madrid region and 24% in Andalucía. Sheep and goat’s milk production is also down 6.5% and 10.8% respectively, authorities have said.
