Current context (26 August 2026): the Union Nationale des Producteurs de Pommes de Terre (UNPT) is warning of a significant decline in France’s 2026 potato harvest. According to the association’s figures released on 24 August, production will be around 23 per cent lower than the previous year as a result of extreme heat and prolonged drought. This matters for Spain’s market because the country sources a large share of its imported potatoes from France and growers in Spain have also reported heat-related yield losses this season. In the short term, the combination of reduced availability in France and lower yields in Spain raises the risk of higher procurement costs for retailers, processors and Gastronomie.
Import dependence and demand: Spain has steadily increased its potato imports from France over the past decade. Industry and foreign trade data put the figure for 2025 at around 941,000 tonnes from France – meaning that nearly three-quarters of imported potatoes now come from its neighbour. Consumption in Spain has recently edged up; national figures from the Ministerio de Agricultura, Pesca y Alimentación show per capita consumption of just over 26 kilograms. Potential supply constraints are therefore meeting stable to rising demand.
Assessment of the sources: UNPT’s figures are a producer forecast, not an official harvest result. Final harvest statistics are generally released later by national authorities and EU bodies. Import and consumption figures are also sometimes available only as provisional campaign and foreign trade data. Reports from Spanish growers about heat-related yield losses concern the current season, but reliable nationwide harvest volumes are not yet available.
Possible impact in Spain: Procurement prices for storage and processing potatoes are likely to rise in autumn if France’s harvest does indeed fall so sharply and Spanish supplies cannot fill the gap. For the food retail and the catering sector, the risk of short-term price adjustments is increasing, particularly for standardised cut products and chips, which depend heavily on French stored potatoes. Spanish growers could also temporarily benefit from firmer producer prices – provided weather conditions and quality requirements allow sufficient marketable volumes.
Questions to watch: the final harvest estimates for France, available stocks, possible rerouting of supply within the EU and the course of Spain’s late season will all be decisive. Only officially confirmed data will make it possible to quantify the potential price impact reliably.
