UK’s Food Security at Risk: Experts Warn Nation May Struggle to Feed Itself in Crisis
August 24, 2025 — Growing concerns have emerged from agricultural experts and food security campaigners about the United Kingdom’s ability to sustain its population with homegrown food supplies in the event of future crises. Despite previous warnings dating back to the COVID-19 pandemic, experts argue that Britain remains dangerously reliant on imported food and remains insufficiently prepared for disruptions to global supply chains caused by pandemics, wars, or climate disasters.
A “Criminal” Dependency on Imported Food
Tom Bradshaw, head of the National Farmers Union (NFU), highlights the UK’s “criminal” dependence on foreign countries to supply essential foodstuffs. He warns that continued reliance on imports without significant changes risks leaving the nation vulnerable if international trade falters.
“We’re living in some of the most volatile geopolitical times we’ve known,” Bradshaw stated. “If we are willing to invest in national defence, we should be having the same conversation about food security.” The NFU chief cautioned that continuing along the current path for another decade may make it “too late to turn the tap back on” to domestic food production.
Volatile Times: Disruptions Are Increasing
The COVID-19 pandemic illustrated the frailty of food supply chains as shoppers encountered empty supermarket shelves for the first time in decades, recalling parallels to wartime blockades. Since then, geopolitical conflicts, such as the wars in Ukraine and Gaza, combined with aggressive changes to global trade policies and escalating climate crises, have only heightened risks.
Professor Tim Benton, former UK food security ambassador and distinguished fellow at Chatham House, underlined the growing urgency. “It’s easy to imagine a prolonged acute problem arising from a significant geopolitical shock. Governments everywhere are concerned about ensuring enough food supply,” he said.
Britain’s Declining Food Self-Sufficiency
According to Department for Environment, Food and Rural Affairs (DEFRA) data, the UK produced just 65% of its food needs in 2024, a decrease from 78% in 1984. The remainder is sourced from imports, making Britain increasingly vulnerable to international disruptions.
Benton attributes this decline to a shift since the 1980s where food security responsibility was handed over to free market forces. Businesses have adopted fragile just-in-time supply chains, while consumers have also adapted to frequent shopping rather than stockpiling staples, further destabilizing the system.
However, DEFRA has acknowledged this growing risk and allocated £11.8 billion towards bolstering food production during the current parliamentary term. Measures such as extending the Seasonal Worker Visa Scheme seek to mitigate labour shortages in agriculture.
The Achilles’ Heel: Fruits and Vegetables
A major concern identified is Britain’s low production of fruits and vegetables, covering just 15% and 53% of its own demand respectively. In comparison, the UK is better at producing meat, potatoes, and wheat. DEFRA figures reveal that only 1% of farmland is dedicated to fruit and vegetable cultivation, while most farmland is used for livestock feed.
Rebecca Tobi, a public health nutritionist with the Food Foundation, warns this imbalance may pose malnutrition risks during import shocks due to insufficient availability of vital micronutrients. Bradshaw remarks, “It is criminal that we are less than 20% self-sufficient in fruit.”
Changing Food Preferences and Market Realities
Britons’ dietary habits complicate the food security challenge. The public’s growing appetite for year-round availability of exotic and out-of-season produce such as strawberries, pineapples, and bananas exacerbates import reliance. Bananas remain the most purchased fresh fruit in UK households despite not being grown domestically.
John Walgate, chief executive of the British Growers Association, observes, “We love foods we will never grow in the UK.” He explains that supply chain and climate risks deter domestic growers from expanding fruit and vegetable production, with market conditions favoring cheaper imports due to high UK labour and energy costs.
The Difficulty of Farming and Investment Challenges
Domestic horticulture faces significant challenges. Growing crops is inherently risky, requiring long-term investment, patience, and adaptation to unpredictable weather. For example, an apple tree takes 20 years to mature, but retailer contracts often last only a few seasons, placing farmers in precarious positions.
Thanet Earth, Britain’s largest greenhouse complex, serves as a case study in innovation, producing millions of tomatoes, cucumbers, and peppers annually through cutting-edge technology that boosts water efficiency and crop yield. Nonetheless, the company has invested tens of millions of pounds to develop facilities that remain financially out of reach for most growers.
In 2023-24, 61% of English farms could not cover their operational costs, highlighting widespread financial strain on farmers. Bradshaw emphasizes the need for consumers to acknowledge the costs of food security through higher prices or increased public subsidies. He notes, “Somebody has to be willing to pay.”
The Way Forward: National Security Through Food Security
Policy experts and farmers urge urgent action to strengthen Britain’s food resilience by revitalizing domestic production and reconsidering dietary expectations. Labour has pledged to treat food security as a matter of national security, suggesting future reforms may prioritize self-sufficiency.
DEFRA has also appointed former NFU president Baroness Minette Batters to spearhead reforms aimed at improving farming profitability and sustainability.
As the UK navigates an increasingly uncertain global landscape, experts agree that food security must be at the forefront of policy discussions. Without decisive intervention, the nation risks facing shortages and malnutrition in future crises — a scenario that many fear may soon materialize.
