Farmland abandonment can be defined as the cessation of agricultural activities on a given surface of land.
This process has been observed in many regions of the European Union (EU) and at different periods, particularly on marginal land. Farmland abandonment has significant environmental consequences and is often associated with social and economic problems in rural areas. For parcels that were previously intensively managed, abandonment has brought environmental benefits, particularly a reduction in agricultural chemicals pollution. For areas that used to be grasslands, and that were valued for their botanical interest or as habitats for breeding and migratory birds (High Nature Value farmland), farmland abandonment entails significant loss of biodiversity.
