UK heatwave crushes crop yields, forces unseasonal imports
Severe drought and heat have devastated UK vegetable crops, forcing unseasonal imports from southern Europe and driving wholesale prices up by as much as 90 percent, threatening to squeeze margins across the food supply chain.
Extreme heat and drought have devastated UK vegetable harvests at the peak of the domestic growing season, forcing supermarkets and caterers to rely on unseasonal imports from Spain and the Netherlands. Wholesale prices have surged in response, with iceberg lettuce up 90 percent, tomatoes rising more than 60 percent and potatoes climbing over 40 percent.
The supply chain disruption is most acute for field crops like broccoli and leafy greens. Yields have halved for some growers. “We are having to put two heads of broccoli together to make the weight the pack is sold in,” said David Simmons of Riviera Produce. To meet demand, the UK is importing broccoli from Spain and Holland, while Simmons warned that cauliflower supplies could be the next to face shortages.
Wholesalers are adjusting their sourcing strategies to navigate the crisis. “It is worse than the public realise. We are running out of water,” said Tim O’Malley, chair of Nationwide Produce. “Last week we did something very unusual and went back to Spain. They have got hot weather but they are more used to farming in these conditions.” The English pea harvest is down by a third, though Scottish growers, accounting for a fifth of UK production, are expecting average yields.
Root vegetables are also facing severe stress, threatening the UK’s high self-sufficiency levels. Britain produces 97 percent of the carrots it consumes, but the main autumn crop is at risk without immediate rainfall. “It’s heartbreaking and wallet-breaking,” said Yorkshire carrot grower Rodger Hobson, noting that temperatures above 25C cause crop shutdown. Domestic carrot supplies could run out months early next spring, necessitating imports. Potato yields are also expected to fall, with GB Potatoes chief executive Scott Walker warning of smaller crop sizes across both the UK and Europe.
The industry is now pressing the government to treat food security as a national priority. Executives from Tesco, Sainsbury’s, Waitrose and Aldi were among more than 100 organisations that wrote to Andy Burnham warning that extreme weather threatens Britain's food system and urging a reduction in import reliance. However, adapting to a hotter climate requires capital investment that farmers currently struggle to afford. Growers are looking at southern European seed varieties and want state support to build reservoirs, but tight margins and slow planning permission processes present significant barriers.
