Summary
This integrated modelling study evaluates options for reforming global agricultural subsidies to align with health and climate objectives whilst maintaining economic viability. The authors find that repurposing up to half of agricultural subsidies to support production of nutritionally and environmentally beneficial crops—including fruits, vegetables, and horticultural products—combined with more equitable global subsidy distribution, could reduce emissions and improve population health without economic loss. The findings suggest that health and climate-driven subsidy reform is both economically feasible and necessary for transitions towards sustainable food systems.
UK applicability
The UK's post-Brexit agricultural policy framework provides an opportunity to apply these principles, particularly through schemes like the new Environmental Land Management (ELM) system. However, the global nature of the modelling means country-specific economic and agricultural contexts would need careful interpretation for UK implementation.
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, and economic welfare using an integrated assessment framework. It identified reform pathways that could simultaneously reduce emissions and improve health without economic losses.
