Varieties of olive tree

Migrations and Rooting of the Olive Tree

Not all olive varieties travel in the same way. Some have crossed continents, adapting to different landscapes and climates. Others have remained stable, rooted in a single continent, where they have shaped biodiversity, culture, and landscape. In this project, the value of a variety does not depend on how far it has traveled, but on how it has inhabited the territories that welcomed it.
