For
millennia, mankind has shaped landscapes, particularly through agriculture
(Figure 1). In Europe, the age-old interaction between humans and ecosystems
strongly influenced the cultural heritage. Yet European farmland is now being
abandoned, especially in remote areas. The loss of the traditional agricultural
landscapes and its consequences for biodiversity and ecosystem services is
generating concerns in both the scientific community and the public. Here we ask
to what extent farmland abandonment can be considered as an opportunity for
rewilding ecosystems. We analyze the perceptions of traditional agriculture in
Europe and their influence in land management policies. We argue that, contrary
to the common perception, traditional agriculture practices were not
environmentally friendly and that the standards of living of rural populations
were low. We suggest that current policies to maintain extensive farming
landscapes underestimate the human labor needed to sustain these landscapes and
the recent and future dynamics of the socio-economic drivers behind
abandonment. We examine the potential benefits for ecosystems and people from
rewilding. We identify species that could benefit from land abandonment and
forest regeneration and the ecosystem services that could be provided such as
carbon sequestration and recreation. Finally, we discuss the challenges
associated with rewilding, including the need to maintain open areas, the fire
risks, and the conflicts between people and wildlife. Despite these challenges,
we argue that rewilding should be recognized by policy-makers as one of the
possible land management options in Europe, particularly on marginal areas.

in the Peneda mountain range, Northern Portugal. Over millennia, forests were
converted to scrubland, cropland and pastures. With the abandonment of
agro-pastoral activities, forest is now expanding from the remnant fragments
and megafauna species are increasing.
