Moving toward the north? The spatial shift of olive groves in Italy

Southern Europe is becoming a hotspot for climate change. Appropriate mechanisation is necessary for reducing soil compacting in such contexts. The olive tree distribution a typical Mediterranean crop showed a well-definedlatitude gradient with progressive decline moving towards the north. Climate change, however, has supposed to cause a significant shift towards the north in the geographical range of olive trees. Our study analyses the spatial distribution of the olive tree area in Italy, a region within the species' ecological range apart from the Northern region, which is now becoming progressively specialised in this crop because of local warming. Results indicate that olive cultivated area increased in Northern Italy, especially in flat districts and upland areas, while decreasing (more or less rapidly) in central and southern Italy because of land abandonment.

Automated summary

Climate change is causing a shift in the geographical distribution of olive trees towards the north, with an increase in olive cultivation area in Northern Italy and a decrease in central and southern Italy due to land abandonment.
