Summary
This narrative review synthesises evidence on how climate change undermines global food system stability, food security, and diet quality with particular impacts on vulnerable populations. The authors document multilevel impacts including soil fertility loss, altered nutrient composition in crops, and increased malnutrition risk, and argue that climate-smart agriculture and resilient food systems coupled with robust measurement tools are essential to ensure nutritious, diverse, and sustainable diets aligned with environmental conservation.
UK applicability
Whilst this is a global review, UK-specific applicability centres on domestic vulnerabilities in food security and nutrition during climate volatility, the need for climate-adapted farming practices to maintain soil fertility and crop nutrient density, and development of national food system resilience indicators. The interaction with pandemic disruptions highlighted is also relevant to UK supply chain and food access planning.
Key measures
Food security indicators, diet quality metrics, nutrient composition and bioavailability, soil fertility measures, crop yield, pest resistance patterns, malnutrition prevalence
Outcomes reported
The review examined how climate change affects food system stability, food security, diet quality, and human nutrition outcomes across vulnerable populations. It identified impacts on soil fertility, crop yield, nutrient composition and bioavailability, pest resistance, and malnutrition risk.
