2. Rationale for this review
• Ecosystem services (ES) are regarded as
the structure and functions of
terrestrial and marine ecosystems that
result in both goods and services being
produced that contribute to support
human wellbeing.
• The last three decades has seen an
exponential rise in ecosystem service
related publications.
• This study will assess the literature
base for both the positive aspects (ES)
and negative functions (EDS) rendered
to agriculture from forests, trees and
agroforestry.
4. Lessons learned
• The temporal and spatial scales of the studies identified in this review point to clear
gaps in the current understanding of the contribution of forest and trees to agriculture
• The majority of studies were conducted in AFS < 4Ha. and over < 3 year study periods
• The majority of studies showed an overall net positive effect of tree presence on one or
more of the following parameters: yield, resource maintenance, biodiversity and
income
• Findings reveal that the provisioning of forest ecosystem services to food production do
not act in isolation and a range of potential outcomes and trade-offs should be
considered in management strategies
