Agroforestry is the practice of deliberately integrating woody vegetation (trees or shrubs) with crop and/or animal production systems to
benefit from the resulting ecological and economic interactions
Silvopastoral systemsCombining trees with forage and animal production. It
comprises forest or woodland grazing and open forest trees
Silvoarable systemsWidely spaced trees inter-cropped with annual or perennial crops. It comprises alley cropping, scattered trees and line
belts
Agroforestry systems
INTENSIFICATION
ABANDONMENT
Homogenization of landscapes
COMMON THREATS
Ruled by the same European policy framework
INTRODUCTION
Current Social demand has changed
New oportunities for agroforestrysystems
Provisioning Ecosystem Services
Supporting Ecosystem Services
Regulating Ecosystem Services
Cultural Ecosystem Services
IPBES theoretical framework
Central hypothesis of agroforestry: integration of trees within agricultural systemsresults in a more efficient acquisition of resources, such as solar radiation, water andnutrients, that the agricultural system would otherwise not acquire (Cannell et al. 1996).

Research questions:1. Does European agroforestry enhance biodiversity and ecosystem services
relative to specialised agriculture or forestry?2. Which categories of ecosystem services are most supported by agroforestry?3. What differences arise between different kinds of agroforestry (i.e.
silvoarable systems, silvopastoral agroforestry)?
