Summary
This chapter, forming part of the IPCC Sixth Assessment Report (AR6) Working Group II contribution, provides a comprehensive assessment of the scientific literature on climate change risks to food systems, covering production, supply chains, and consumption. It evaluates both the biophysical and socioeconomic dimensions of food insecurity under different warming scenarios, and examines the potential of mitigation and adaptation strategies to reduce risk. The chapter synthesises evidence across diverse farming systems, geographies, and population groups, with particular attention to vulnerabilities in low-income and food-insecure regions.
UK applicability
Although the chapter is global in scope, its findings are directly relevant to UK food security policy, particularly regarding import dependencies, climate-related supply chain disruption, and the need for adaptation planning in UK agriculture under projected warming trajectories.
Key measures
Food security indicators; crop yield projections under climate scenarios; adaptation feasibility and effectiveness; nutrition and diet outcomes; supply chain vulnerability metrics
Outcomes reported
The chapter assesses observed and projected climate change impacts on food production, food security, and nutrition, alongside adaptation options and their feasibility across different food system components and regions.
