Supermarket prices for melons in Italy have seen a significant increase of nearly 40% over the past five years, according to research by Agroter, while sales have slightly decreased by 4%. This price hike is due to a reduction in discount campaigns and promotions by Italy's largest retailers. Melon suppliers, facing rising costs due to factors such as energy prices and climate change, welcome this trend. Francesca Nadalini of Sermide Ortofruit notes the unpredictable nature of production costs in the greenhouse industry.
