Summary
This global meta-analysis of 60 crops across six continents examined how landscape context mediates the sustainability benefits of organic agriculture relative to conventional systems. The research found that whilst organic sites consistently showed greater biodiversity and profitability than conventional sites, the magnitude of these benefits varied substantially by landscape type: biodiversity gains were largest in landscapes with large field sizes, whereas economic benefits were most pronounced in small-field landscapes. The findings suggest that the ecological and economic sustainability outcomes of organic farming are not uniform across all contexts but instead depend critically on pre-existing landscape characteristics and composition.
UK applicability
The findings are potentially relevant to UK agricultural policy and farm planning, as the UK contains diverse landscape types (from intensively managed arable regions to mixed and pastoral landscapes). The trade-off between ecological benefits (favoured in large-field, simplified landscapes) and economic benefits (favoured in complex, small-field systems) may inform decisions about where to prioritise organic production support or conversion incentives.
Key measures
Biodiversity indices, crop yields, farm profitability, landscape metrics (percent cropland, compositional and configurational heterogeneity, field size)
Outcomes reported
The study assessed whether landscape context (field size, cropland proportion, and landscape heterogeneity) affects biodiversity, crop yield, and profitability outcomes in organic versus conventional farming systems across 60 crop types globally. Results indicated that landscape composition and configuration substantially mediate the sustainability benefits of organic agriculture.
