Options for reforming agricultural subsidies from health, climate, and economic perspectives

Summary

This integrated modelling study examines how global agricultural subsidy schemes could be reformed to align with health and climate objectives whilst remaining economically viable. Using economic, environmental and health assessment frameworks, the authors demonstrate that repurposing up to half of agricultural subsidies towards nutritionally and environmentally beneficial crops (fruits, vegetables, horticulture), combined with more equitable global subsidy distribution, could reduce greenhouse gas emissions and improve population health without diminishing economic welfare. The findings suggest subsidy reform is both technically feasible and economically rational as a lever for sustainable food system transition.

Regional applicability

The United Kingdom operates within a reformed post-Brexit agricultural policy framework (the Agriculture Act 2020) and could apply these findings to subsidy redesign. The emphasis on horticulture production aligns with UK food security and domestic fruit and vegetable supply concerns, though the modelling is global and local agricultural capacity and market structures would require contextualisation. Implementation would need to balance these recommendations against domestic farming economics and UK trade priorities.

Key measures

Greenhouse gas emissions reductions (likely CO₂-equivalents); population health improvements (mortality or disease burden metrics); economic welfare changes; subsidy repurposing scenarios (up to 50% reallocation); 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 at the global scale. Results demonstrated that repurposing subsidies towards fruits, vegetables and horticultural products whilst distributing payments more equitably could achieve simultaneous improvements in health and environmental metrics without economic loss.
