Europe's olive producers are facing a significant decrease in olive oil production due to drought and extreme heat, with estimates predicting a global shortage of around four thousand tons, leading to a potential 30-50 percent price increase. The most affected countries are Italy, Greece, Spain, and Portugal, with Italy expected to produce 37 percent less olive oil in the 2022-2023 season. The quality of the olives is also being negatively impacted, and experts are seeking fertile varieties and advising significant investments in irrigation techniques to combat pathogens and extreme weather.
