Summary

This study investigates the relationship between pollinator dependence and the conventional-to-organic yield gap across a range of crop species, drawing on data from multiple studies in a meta-analytical framework. The findings suggest that the productivity disadvantage typically associated with organic farming diminishes as crop reliance on pollinators increases, implying that organic management practices — which tend to support more diverse and abundant pollinator communities — may partially offset yield losses in pollinator-dependent crops. The work contributes to ongoing debates about the viability and ecological co-benefits of organic farming systems relative to conventional agriculture.

UK applicability

The findings are broadly applicable to UK conditions, where pollinator-dependent crops such as oilseed rape, field beans, and soft fruit are economically important and where organic area has been expanding. UK policy discussions around agri-environment schemes and farming system transitions may benefit from evidence that organic systems can be comparatively competitive in pollinator-dependent crop sectors.

Key measures

Yield ratio (organic:conventional); pollinator dependence index; crop type; yield gap magnitude across crop categories

Outcomes reported

The study examined how the yield difference between conventional and organic farming systems varies according to the degree to which individual crops depend on pollinators for reproduction. It likely reports that the conventional-to-organic yield gap narrows or closes for crops with high pollinator dependence, suggesting organic systems may better support pollination services.
