Britons are being advised to stockpile food to prepare for potential crises that could disrupt the nation's food supply, according to a report from the National Audit Office (NAO).

The NAO stated that short and long-term risks to food supplies are becoming "more likely and potentially more severe." Experts are urging ministers to collaborate with households and businesses to bolster the resilience of the food supply chain against unexpected events.

The UK government designates food as one of 13 critical national infrastructure sectors essential for the country's functioning. However, the NAO contends that the Department for the Environment, Food and Rural Affairs (Defra) has "done too little in recent years" to encourage preparedness among businesses and families.

The report suggests that British households are less prepared for emergencies compared to those in other nations. Businesses have also indicated that Defra's engagement with them has decreased, and they are not being consulted on future preparedness plans.

The last exercise to test Defra's readiness for catastrophic events that could disrupt the food supply chain occurred in 2023. The NAO also highlighted that Defra currently lacks the necessary legal powers to compel companies to take emergency action during such a crisis.

Gareth Davies, head of the NAO, referenced recent disruptions, including the COVID-19 pandemic and the war in Ukraine, stating, "Recent disruptions have shown the resilience of the UK's food supply chain, but risks are increasing in likelihood and severity. Defra should learn from other countries, and strengthen preparedness for emergencies."

Environmental factors are also contributing to concerns, with farm crops facing devastation from wildfires and drought. The National Farmers Union has expressed increasing concern, noting that dairy farmers are already utilizing winter feed due to a lack of grass growth.

Supermarket leaders, including Ken Murphy of Tesco and Simon Roberts of Sainsbury's, have called for increased food self-sufficiency within the UK.

In response, Defra stated, "The Prime Minister has made clear that food security is national security. The NAO's report shows risks to food supplies are becoming more complex. We are working with farmers and the food and drink industry to strengthen the UK's food security and resilience." The department added that it would "carefully consider the report's findings and recommendations as part of our ongoing work to build a more resilient, productive and sustainable food system."
