Is there robust evidence on the impacts of agroforestry?

To do so, scientific articles on ecological, economic, and social impacts of agroforestry compared to a control system were sought using a systematic literature review. 64 systematic reviews and meta-analyses were identified and evaluated in an Evidence Gap Map. The thematic and geographic coverage of studies was mapped to identify density and research gaps in the evidence base.

The Evidence Gap Map shows whether and in which areas the research landscape allows conclusions to be drawn about potential advantages or disadvantages of agroforestry compared to segregated land use systems. The study indicates that ecological effects related to climate change, water, biodiversity, soil and pest control, and productivity aspects have been intensively studied. Research gaps were identified, for example, for individual silvopastoral and agrosilvopastoral practices, and for the social impacts of all agroforestry practices.

The results of the study highlight the need for further research, but also urge caution in making generalized statements about the benefits of agroforestry for policy making or land use planning.
