Summary
This second-order meta-analysis of 5,160 original studies demonstrates that agricultural diversification practices enhance multiple ecosystem services—including pollination, pest control, nutrient cycling, soil fertility, and water regulation—without reducing crop yields. The analysis distinguished between practices targeting aboveground biodiversity (which improved pest control and water regulation) and those targeting belowground biodiversity (though the abstract text is incomplete regarding their specific benefits). The findings suggest diversification can reduce agronomic input dependency whilst maintaining productive capacity.
Regional applicability
The international scope of this synthesis suggests findings are likely applicable to United Kingdom cropping and mixed farming systems, particularly regarding pest control and soil fertility enhancement through diversification. UK producers seeking to improve resilience and ecosystem services within existing yield constraints may find the meta-analytical evidence directly relevant to decision-making.
Key measures
Biodiversity indices, pollination rates, pest control effectiveness, nutrient cycling, soil fertility metrics, water regulation, crop yield
Outcomes reported
This second-order meta-analysis synthesised 98 meta-analyses comprising 5,160 original studies to assess the impact of diversification practices on above- and belowground biodiversity, ecosystem services, and crop yields. The study quantified effects across multiple ecosystem services including pollination, pest control, nutrient cycling, soil fertility, and water regulation.
