|Abstract: ||Mediterranean landscapes, date back at
least to the ancient Greek civilizations (1)
and hold cultural, scenic, and biodiversity
value (2). However, as demand for olives
and olive oil has increased (3), traditional
groves, the least viable in economic terms,
have been abandoned and production has
shifted to large-scale intensive plantations to maximize yields (3–5). These vast
groves use irrigation, high tree densities,
agrochemicals, and mechanization (6).
The resulting landscape simplification and
habitat loss and degradation contribute
to substantial biodiversity decline (6, 7).
There are also claims that harvesting olives
at night leads to mass bird mortality (8)
and that the olive industry affects water,
soil, and human health (5).
A thorough understanding of the
environmental impacts of modern olive
farming is urgent to inform agricultural
policies and consumers. In the European
post-2020 agricultural policy proposal (9),
currently under discussion, most farmers

The environmental value of traditional olive groves,
such as this one in Portugal, has been overlooked.
are required to comply with basic environmental standards. However, the olive
sector is exempted from environmental
requirements (10). This should be changed
in order to promote the maintenance of
traditional olive groves, limit the area
occupied by continuous olive tree monocultures, and introduce environmentally
friendly management practices. Because
organic production labels focus mostly
on fertilizers and pesticides, they do not
provide enough information to consumers. To facilitate informed choices, new
labels should be created. Olive oil packaging should provide consumers with
details about the grove from which the
product was sourced. Biodiversity-rich
groves that host rare species of plants and
animals could benefit from this marketing.
Enhancing and highlighting the sustainability of olive farming are important not
only for the environment but also for the
economic revenues of olive oil producers|
