Summary

This paper synthesises findings from the September 2021 United Nations Food Systems Summit, which convened delegates from 183 countries to address three critical disruptions to global food systems: environmental climate change, COVID-19 disease, and conflict. The authors argue that business-as-usual approaches are insufficient to meet sustainable development goals and call for urgent, large-scale systemic action to mitigate threats to food security and nutrition globally.

UK applicability

The findings underscore the UK's exposure to global food system disruptions through trade dependencies and climate impacts. The paper's call for systemic transformation is relevant to UK food policy development, particularly in the context of post-Brexit agricultural and trade policy, resilience to international supply chain shocks, and alignment with net-zero and food security objectives.

Key measures

Food security, hunger, malnutrition, undernutrition, sustainable development goal achievement

Outcomes reported

The paper reports on key threats to global food security and nutrition identified at the UN Food Systems Summit, specifically examining how climate change, COVID-19, and conflict disrupt food systems and progress on hunger and malnutrition mitigation.
