Spanish chestnut producers are facing a difficult year as they anticipate a reduction in the useful harvest of between 20% and 80% due to the lack of rain and the spread of fungal pests. The Bierzo region has been particularly affected, with half of the chestnut production expected to be lost due to the gnomoniopsis fungus. Drought and climate change have also impacted chestnut harvests in areas such as Huelva, Extremadura, and Malaga, leading to significant declines in production.
