UK Food System at Risk of Crisis, Warn Experts Cyberattacks, Extreme Weather, and War Cited as Top Threats
A new analysis by over 30 UK food system experts warns that chronic vulnerabilities including climate change, low incomes, fragile supply chains, and poor farming policies have left the country’s food system dangerously exposed. Without intervention, shocks like extreme weather, cyberattacks, or international conflicts could trigger price surges, social unrest, and even food riots.
The study, published in Sustainability, found that 80% of experts believe large-scale violence linked to food shortages is possible within 50 years, with 40% predicting it could occur within the next decade. The worst-case scenario envisions over 30,000 violent injuries in a single year due to food-related protests or riots.
Recent events underscore the risks: cyberattacks disrupted major UK supermarkets in 2025, while droughts and Russia’s invasion of Ukraine have already driven up food costs. One in seven UK households faced food insecurity in 2025, according to the Food Foundation.
The researchers identified three primary threats:
- Extreme weather, disrupting domestic and global production.
- Cyberattacks, targeting digitized supply chains.
- War or geopolitical conflict, cutting off imports (the UK relies on imports for 35% of its food).
Global supply chain pinch points, such as the Suez Canal, and over-reliance on "breadbasket" nations like the US and Russia further heighten risks. Social factors including distrust in government and the stigma of food insecurity could amplify unrest.
Experts urge coordinated action, including regenerative farming, emergency cash transfers, and inclusive planning with marginalized communities. While the UK government has invested in climate-resilient crops and supply chain technology, the report stresses that systemic resilience is critical to preventing a full-blown crisis.
