Summary
This modelling study, published in The Lancet, projects the health implications of climate change on global food production through 2050 under multiple climate and socioeconomic scenarios. The authors integrated agronomic, economic, and epidemiological models to estimate how shifts in crop yields, food prices, and dietary composition would affect population-level nutrition and diet-related disease burden across regions. The work suggests climate change poses substantial risks to human health through its effects on food systems, with implications for global nutrition policy and adaptation strategies.
UK applicability
As a high-income nation with diversified food imports, the United Kingdom faces health risks primarily through global food price volatility and supply disruption rather than local production collapse. Findings may inform UK climate adaptation planning, trade policy, and public health nutrition strategies, particularly regarding food security resilience and dietary transition planning.
Key measures
Health outcomes including mortality and morbidity attributable to changes in food availability and dietary intake; nutritional adequacy metrics; regional variation in health effects
Outcomes reported
The study modelled how climate change will affect future food production and assessed the resulting health effects across global and regional populations. It evaluated nutritional adequacy, diet-related mortality, and health burden under different climate and socioeconomic scenarios.
