How Will Climate Change Impact UK Food Supply Chains?

The UK finds itself at a precarious juncture as various external pressures threaten the stability and resilience of its national food supply.

As climate change accelerates, geopolitical issues emerge and trade dynamics evolve, the country's food security is increasingly jeopardised.

Nearly one-third of the UK's food imports come solely from the EU, leaving the nation highly vulnerable to any disruptions in international trade.

The National Preparedness Commission (NPC) has warned that the country is not prepared for the scale of risks now facing its food supply. From climate change and geopolitical tensions to economic shocks and trade barriers, these challenges are making the current system unsustainable.

The risk landscape

The depth and variety of risks facing the UK's food supply are significant.

Extreme weather conditions, economic shocks resulting from global events such as Russia’s invasion of Ukraine and the COVID-19 pandemic, as well as trade barriers and geopolitical tensions, collectively buffet the UK's food supply infrastructure.

Tim Lang, Emeritus Professor of food policy at City University of London and author of the report, argues that the UK’s food resilience framework is dangerously outdated.

“The UK’s post-war food system, while revolutionary in its time, is no longer fit for purpose. To safeguard our future, we must prioritise resilience at every level – from local communities to national frameworks,” he says.

Adding to these complications are the escalating food prices, now 25% higher than in recent years.

The delicate balance of the food supply is also rocked by Britain's worst domestic harvest since 1983, largely due to extreme climatic disruptions, emphasising the need for a strategic realignment of the food security protocol.

Lord Toby Harris, Chair of the NPC, highlights the severity of the issue: “Food security is a cornerstone of national resilience. This report highlights the urgent need for a coordinated, whole-society approach to ensure that no one in the UK is left vulnerable in the face of future crises.”

Proposed strategic directions

The NPC report calls for legislative action, suggesting that food security should be a significant legal mandate, akin to national security or energy.

A proposed Food Security and Resilience Act could possibly enshrine food security into law, recognising it as a critical element of the UK’s national infrastructure.

Current initiatives and risk assessments like the National Risk Register fail to adequately consider the multifaceted nature of food supply risks.

The report recommends a comprehensive overhaul, urging the establishment of a National Food Security Council.

This council would serve as a nexus for coordination, bringing together government bodies, food industries and retailers to ensure a unified and robust approach to food security.

The report also recommends a shift from the prevalent 'just-in-time' logistics model to a more robust 'just-in-case' strategy.

This strategy envisions sturdier food reserves, enhanced storage facilities and a more interconnected chain between food producers and retailers, all aimed at insulating the nation from sudden market shocks and supply disruptions.

Tim stresses that food security is not just about having enough supply but also about ensuring affordability and accessibility: “There is too much complacency about UK food security and civil food resilience barely features at all in forward planning.”
