Summary
This integrated modelling study examines options for reforming global agricultural subsidies to align with health and climate objectives whilst maintaining economic feasibility. The authors demonstrate that repurposing subsidies towards nutritious horticultural products and equalising subsidy distribution could yield reductions in agricultural greenhouse gas emissions and population health gains without reducing economic welfare, suggesting a viable pathway towards more sustainable food systems.
UK applicability
The findings are relevant to UK agricultural policy reform, particularly post-CAP transition discussions. However, direct application would require contextualisation to UK subsidy scales, domestic production patterns, and regional variation in horticultural capacity and competitiveness.
Key measures
Greenhouse gas emissions reductions; population health improvements; economic welfare; subsidy repurposing scenarios; global subsidy distribution equity
Outcomes reported
The study modelled the effects of various agricultural subsidy reform options on greenhouse gas emissions, population health outcomes, and economic welfare using an integrated assessment framework. The analysis identified reform pathways—including repurposing up to half of subsidies towards fruits, vegetables, and horticultural production—that could simultaneously reduce emissions and improve health without economic loss.
