Italy sees 57% drop in olive harvest as result of climate change, scientist says

Extreme weather blamed for plunge in country's olive harvest - the worst in 25 years - that could leave the country dependent on imports by April

Extreme weather events have been the "main driver" of an olive harvest collapse that could leave Italy dependent on imports from April, a leading climate scientist has warned.

A 57% plunge in the country's olive harvest - the worst in 25 years - sparked protests by thousands of Italian farmers wearing gilet arancioni - orange vests - in Rome earlier this month.
