Summary
This modelling study applies an integrated global food and land system framework to evaluate 23 food system transformation measures across 15 sustainability and health indicators through 2050. The authors demonstrate that whilst individual measures involve trade-offs, their combined implementation can substantially reduce mortality burden, environmental impacts and poverty whilst enabling achievement of the 1.5 °C climate target. The findings suggest that coordinated food system and climate policy outside agriculture is necessary to reconcile health, environmental and social objectives.
UK applicability
The study's global modelling provides a systems-level perspective relevant to UK food policy integration, particularly for setting nutrition and climate targets in the forthcoming Food Strategy. However, the abstract does not clarify regional granularity; UK-specific applicability would require assessment of how global measures translate to domestic agricultural and trade contexts.
Key measures
Mortality impact (life years lost annually), nitrogen surplus, absolute poverty prevalence, greenhouse gas emissions, climate target feasibility (1.5 °C)
Outcomes reported
The study quantified the impact of 23 food system measures on 15 outcome indicators spanning public health, environment, social inclusion and economy through 2050. Key outcomes measured include annual mortality reduction, nitrogen surplus change, absolute poverty impacts, and climate mitigation potential.
