Vegetable lovers across Europe have been making hard decisions this winter after storms battered the fields in southeast Spain, the continent's main fruit and vegetable patch. Zucchini prices are soaring, but shoppers are also thinking twice before shelling out for pricier tomatoes, peppers and eggplants. Some British supermarkets have even resorted to rationing the sale of broccoli and lettuce in light of plummeting harvests. The vast fields along Spain's Mediterranean coast usually stay warm enough to produce year-round, even in the winter. But torrential rains hit the region in late December, followed by shock snowfalls in January -areas near Murcia, in the heart of the farming zone, had not seen a snowflake in 34 years. For most of the year, Spain supplies around 30 percent of the fresh fruits and vegetables on European shelves. In the winter, this proportion rises to half -and to a whopping 80 percent when it comes to lettuce. After the bad weather hit, a Spanish federation of agricultural exporters reported a 30-percent drop in European shipments. The COAG farmers' union says output has halved in the worst-hit regions. Some farmers "have lost their entire crop," said Andres Gongora, COAG'S Almeria director.The province of Murcia, which exports two-thirds of Spanish lettuce, a trade worth 423 million euros ($450 million), has been hit particularly hard. Young lettuces, growing in open fields after sprouting from seeds in greenhouses, were destroyed. After the foul weather receded, a thick coat of thawed mud held up replanting in many places. Adding to the veggie crunch, there has also been heavy snowfall in northern Italy, another major supplier to Europe. Thousands of growers there have lost their crops, with expected losses of around 400 million euros, according to Italy's main farmers' union.The double whammy is now being felt in European stores. Lettuce prices have doubled in Germany and even tripled in Finland. In France, zucchinis fetched four to five times their normal price in mid-January.Spanish supplies of iceberg, romaine and other types of lettuce had already been hit by a dry autumn, and artichoke harvests fell by a fourth. Many shoppers have vented their anger on social media, using hashtags like #lettucecrisis and #courgettecrisis. Spain's agriculture minister expects production to recover in a few weeks, with producers aiming to be back on track by early March. But for lettuce grown in open fields, the wait could extend into April. For Alan Clarke, a strategist at Scotiabank in London, the price increases could spill over into processed food products, such as veggie burgers and other ready-to-eat meals.
