UK Food System a 'Tinderbox' at Risk of Riots from Single Shock, Experts Warn
Dozens of the UK's leading food experts have issued a stark warning that the nation's food system is a 'tinderbox' poised for potential social unrest, including food riots, if triggered by a single major shock. Chronic vulnerabilities, such as the climate crisis, low incomes, poor farming policies, and fragile just-in-time supply chains, have left access to food dangerously exposed, according to a new analysis published in the journal Sustainability.
Systemic Vulnerabilities and High-Risk Shocks
The researchers, who consulted over 30 experts from academia, government, and industry, identified a series of chronic issues making the UK's food system vulnerable. These include:
- Climate crisis impacting agricultural yields and stability.
- Low incomes exacerbating food insecurity, with one in seven families affected in 2025.
- Poor farming policy undermining domestic production resilience.
- Fragile just-in-time supply chains reliant on imports, with about 35% of food currently sourced from abroad.
They then analysed potential shocks that could escalate this fragile situation into a full-blown food crisis. The top three high-risk shocks identified are:
- Extreme weather events, such as droughts or floods, which have already increased food costs globally.
- Cyber-attacks, as seen in incidents affecting major supermarkets like Co-operative and Marks & Spencer in 2025.
- International conflicts, exemplified by Russia's invasion of Ukraine disrupting trade routes.
Any combination of these shocks could disrupt supply chains, spike food prices, and lead to widespread fear, potentially resulting in violence or riots, the analysis concluded.
Alarming Predictions and Social Factors
A related 2023 analysis revealed that 80% of experts believe large-scale violence from a food crisis is possible within the next 50 years, with 40% foreseeing it within a decade. The worst-case scenario envisions over 30,000 people suffering violent injuries in a year due to food-related demonstrations or riots.
The study emphasised that social factors play a critical role. 'A UK food system crisis could arise from hunger and resulting feelings of despair when coupled with a lack of trust in government,' the researchers noted. Dominic Watters, a researcher with lived experience of food poverty, highlighted that crises stem from a 'lack of dignity, voice, and care,' not just calorie shortages, urging for co-designed responses with marginalised communities.
Calls for Urgent Action and Resilience Building
Addressing these systemic vulnerabilities is urgent, the researchers stressed. Recommendations include:
- More coordinated action by government and businesses to enhance food security.
- Diversifying and increasing resilient domestic food production through regenerative agriculture.
- Implementing cash transfers to support the poorest during emergencies.
- Establishing a national forum on preparedness that includes marginalised voices.
Professor Sarah Bridle from the University of York, who led the analysis, stated: 'The stability of the UK's food system is a critical aspect of national security. While we can't always prevent future shocks, we can build resilience to withstand them, and stop a bad situation from becoming a crisis.' Professor Aled Jones of Anglia Ruskin University added that policymakers must adopt a long-term perspective to planning.
Government Response and Global Context
A UK government spokesperson responded, asserting that food security is national security, built on strong domestic production and stable trade routes. They cited investments in technology, streamlined regulation, and support for farmers to boost resilience.
Globally, concerns mirror those in the UK. Álvaro Lario, president of the International Fund for Agricultural Development, recently warned that 'fragile food systems pose an underestimated risk to global stability.' The analysis also pointed to vulnerabilities like concentrated global food production in 'breadbasket' countries and pinch-points such as the Suez canal, which centralise and digitise systems, increasing exposure to cybersecurity threats.
