UK food security under threat as rising input costs and supply chain fragility draw scrutiny

British food producers are intensifying warnings regarding the vulnerability of the nation’s supply chains, citing a convergence of rising operational costs and climatic instability. Jamie Burrows, chair of the crops board at the National Farmers’ Union, described the current environment as extremely difficult for arable farmers. Speaking from his farm in Norfolk, Burrows highlighted that many capable and efficient growers are struggling to finance the crops they are required to plant. He cautioned that some businesses may not survive the current pressures, reflecting a broader concern among the agricultural sector about the precarity of the UK’s food production base.

The immediate financial strain on farmers is driven by significant increases in essential inputs. The cost of red diesel, which is used for agricultural machinery and taxed at a lower rate than standard fuel, has nearly doubled since the conflict in Iran began in late February. Simultaneously, the price of most fertilisers used for crop production and animal feed has surged by approximately 20% over the same period. These economic headwinds follow a period of severe weather, with the UK experiencing its hottest summer on record. The resulting heatwaves and drought conditions led to England’s worst recorded cereals harvest, according to official production estimates. Farmers, who form the first link in the food chain, are now adding their voices to a growing chorus of experts and businesses warning about the fragility of the national food supply.

In response to these mounting concerns, the public accounts committee of parliament is set to begin a series of hearings to examine the resilience of the UK’s food supply. The inquiry will scrutinise findings from the National Audit Office, which identified shortcomings in the last catastrophe planning exercise conducted by the Department for Environment, Food and Rural Affairs. The NAO noted that the exercise largely excluded food supply chain businesses, a gap that has drawn criticism from food experts and academics. These stakeholders have urged the government to treat food security as a national security issue, pointing to threats from the climate crisis, geopolitical shocks, energy outages, and cyber-attacks.

Despite these warnings, the government has taken steps to encourage household preparedness. The Cabinet Office is launching a campaign advising residents to stockpile tinned foods and other non-perishable items, such as bottled water and canned meat, fruit, and vegetables. The government’s Prepare website outlines these measures as part of broader emergency planning. However, a recent letter signed by more than 150 food experts and academics accused ministers of complacency, arguing that there is no adequate plan to feed the population in an emergency. Professor Paul Behrens of the Oxford Martin School at the University of Oxford, who signed the letter, noted that while the UK has historically managed specific events such as the pandemic, it is now entering a period where multiple crises are impacting the system simultaneously.

Structural vulnerabilities within the distribution network have also been highlighted by experts. Professor Tim Lang of the Centre for Food Policy at City St George’s, University of London, has warned that the UK’s food distribution system is highly concentrated. This concentration leaves the network exposed to disruption or targeting by malicious actors. The industry body the Cold Chain Federation has noted that most food imports enter the country through just four ports: Dover, Felixstowe, Southampton, and London Gateway. Furthermore, the UK’s supermarket network is supplied by only 131 distribution hubs serving 12,300 stores. The government wound down the strategic food stockpile that had been maintained since the Second World War in the 1990s, a decision that contrasts with the approach of Scandinavian nations, which have invested in greater national preparedness and local production.

Industry leaders are calling for a fundamental rethink of the food supply chain. Rob Haward, chief executive of Riverford, an organic vegetable box delivery company, stated that the sector requires a different vision for future security. Riverford distributes approximately 65,000 boxes a week, with about 70% of its produce grown in the UK, though it also maintains long-term relationships with growers in Spain and Italy. Haward suggested that longer-term contracts could provide farmers with the confidence to invest in their land and restore soils to better withstand climate change. He also advocated for government intervention, such as offering lower business rates to greengrocers, and encouraged consumers to return to eating more seasonally to reduce reliance on imports of produce that cannot be grown domestically in large volumes.
