From Brittany's lettuce fields to Italy's parched plains, a continent-wide crisis is rewriting what European agriculture can produce.
On a normal summer, Eric Legras notes, at least one French growing region escapes the worst — a quiet buffer against catastrophe. This year offered no such escape. "All our main production areas have been hit, and at the same time," Legras, a spokesman for France's 4,400-member canned and frozen vegetable producers' association, told Le Monde. That single observation captures the scale of what is unfolding: a drought so broad and so deep that the usual geography of resilience has simply ceased to exist.
The numbers from France alone are staggering. Broccoli yields are down 60%, artichoke losses range from 50% to 100%, and pea harvests have fallen by 40% compared with previous years. Maize production — France is Europe's largest grains producer — is projected to drop 35% on 2025 levels to roughly nine million tonnes, a figure not recorded since 1980. The agriculture ministry attributes part of the shortfall to farmers switching to sunflowers, but much of it reflects temperatures that have routinely exceeded 35°C during the precise windows when crops are most vulnerable to heat stress.
The consequences cascade well beyond the fields. Dairy farmers are reporting milk yields down 10–15%, because cows begin to suffer heat stress above 25°C. More urgently, hay production for winter cattle feed is running approximately 30% below the 1989–2018 average — a gap that, according to the ministry's statistical service Agreste, is still widening. Egg output, meanwhile, has fallen by around one million units per day after catastrophic poultry mortality during the June heatwave.
