Summary
This global meta-analysis of 60 crops across six continents examined how landscape context modulates the sustainability benefits of organic relative to conventional farming. The findings reveal landscape-dependent trade-offs: organic sites showed greater biodiversity than conventional ones, with the largest benefits in landscapes characterised by large field sizes, whilst organic profitability advantages were greatest in landscapes with small fields. The results suggest that the ecological and economic benefits of organic agriculture are not uniformly distributed across all landscape types, implying that targeted placement of organic production in suitable landscapes could optimise multiple sustainability outcomes.
UK applicability
The findings are potentially relevant to UK agricultural policy and farm management given the UK's diverse landscape contexts ranging from intensive arable regions to small-scale mixed farming areas. However, direct application would require consideration of whether UK-specific landscape characteristics and socioeconomic contexts align with the meta-analytical patterns identified across global datasets.
Key measures
Biodiversity (species richness/diversity), crop yield, farm profitability, landscape composition (percent cropland), compositional heterogeneity (number and diversity of cover types), configurational heterogeneity (spatial arrangement of cover types)
Outcomes reported
The study assessed whether landscape context (composition and heterogeneity) modulated the sustainability benefits of organic relative to conventional farming across three key metrics: biodiversity, crop yields, and profitability. Analysis spanned 60 crop types across six continents using meta-analytical methods.
