Summary
This 2018 narrative review by Fanzo and colleagues examines how climate change disrupts food systems globally and the resulting implications for nutritional security and health outcomes. The authors synthesise evidence linking environmental stressors (temperature, precipitation variability, extreme weather) to changes in agricultural output, food availability, and dietary quality, with particular attention to nutritionally vulnerable populations. The work frames nutrition as a systems-level outcome dependent on climate-resilient production and equitable food supply chains.
Regional applicability
The review's global scope and focus on food supply chain vulnerability is relevant to UK food security policy, particularly regarding imported commodity dependence and the nutritional risks posed by climate impacts on major trading partners. UK-specific applicability would require assessment of domestic production resilience and adaptation capacity in temperate arable and pastoral systems.
Key measures
Agricultural productivity, food supply chain resilience, dietary adequacy, micronutrient availability, chronic disease risk as mediated by climate-driven food system stress
Outcomes reported
The review synthesises evidence on climate change effects across food systems (agricultural production, supply chains, food availability) and their cascading consequences for nutrition outcomes and health status, particularly in vulnerable populations.
