MANY shoppers have struggled to find their favourite fruits and vegetables in recent days, with many store shelves appearing barren.
Carol Wagstaff, professor of crop quality for health at the University of Reading, has explained why this has happened.
She said: “Many of our retailers and food service providers are struggling to meet orders and consumer demand for crops such as tomatoes, cucumbers, peppers and broccoli.
“Poor weather in Spain, which has seen snow storms, heavy rainfall and thunderstorms recently, is the underlying cause of these shortages.”
Prof Wagstaff added that crops are sown weeks and months in advance, with growers having to predict how long they will take to reach harvest maturity.
They are vulnerable to cold or wet weather strikes, with plant growth slowing down or, in some cases, halted.
She said: “Climate change is causing an increased frequency of extreme weather events which will make our supply of fresh food more vulnerable.
“Although it would be good to grow more of our food in the UK, we have to recognise that to produce crops out of season requires high energy for additional heating and artificial lighting of glasshouses and polytunnels – and we would need to be confident that this comes from renewable sources to avoid simply adding to the challenges of climate change.
“If we only eat vegetables that are in season, then at this time of year we would really struggle to eat the five-a-day that we need as part of a healthy diet.”
