Italy is facing a major climate change crisis as the country’s olive harvests continue to decline. Italy’s olive industry has witnessed a 57 percent decrease in olive production, and according to a leading climate scientist, extreme weather is at the forefront of the crop shortage.
Olive tree farms across Italy have been devastated by weather-related events this past year, including heavy rainfalls, unpredictable frosts, droughts and powerful winds. All of these weather patterns coincide with what climate scientists have predicted would happen in the event of global warming.
“There are clear observational patterns that point to these types of weather extremes as the main drivers of [lower] food productivity,” Professor Riccardo Valentini explained.
Valentini noted that below-zero temperatures are not common in Italy, and extremes like this were foretold through climate change models. Research from the United Nation’s climate change panel also predicted similar weather patterns and indicates that the worst is yet to come.
When it comes to olive trees, any abrupt change in temperature can have a devastating effect on the harvest. Valentini explained how a day or two of freezing temperatures can harm the trees and hurt their development. After they have experienced extreme weather, the trees never fully recover and are more susceptible to disease and pest infestations.
As a whole, temperatures in Italy and the surrounding Mediterranean have gone up by around 1.4C over the past century, while rainfall has decreased by a staggering 2.5 percent. The changes in weather have cost the country over 1 billion dollars in olive production. Government officials are scrambling to come up with a viable solution but have yet to offer any resources for farmers in the region.
Italy is not the only country affected by the changes in weather. The European commission recently predicted that olive harvests in Portugal will decline by around 20 percent this coming year. Greece will take a much larger hit with a decline of around 42 percent. All signs point to a continually increasing problem for European countries, as putting a stop to climate change is proving to be an intricate issue.
