Britain is facing a growing food security challenge, with experts warning that extreme weather, rising inflation, and global conflicts are putting the nation at risk. Industry figures say the government is not responding urgently enough to mounting threats to the UK’s food system.
Extreme Weather and Rising Costs Strain Domestic Production
Farmers are already under severe pressure following a dry spring and an ongoing heatwave. Crops are expected to yield less as temperatures rise beyond their tolerance, while livestock face heat stress and an increased risk of wildfires. Economic losses could reach hundreds of millions of pounds.
Food prices were already projected to be 50% higher this November compared with five years ago, and the extreme weather is compounding inflationary pressures. Even if the Iran war eases, fuel and fertiliser costs are likely to remain high until supply chains through the Strait of Hormuz are restored.
Calls for a Stronger National Food Strategy
A group of nine food experts, including Mike Barry of Marks & Spencer and Anna Taylor of the Food Foundation, wrote to ministers urging the National Food Strategy to be updated. They called for three main priorities: boosting resilient domestic production of healthier food, preparing for supply chain shocks, and ensuring access to safe, affordable food for all.
Professor emeritus Tim Lang of City St George’s University criticised the government’s current approach as “business as usual” and warned that warnings on food security were being ignored. He said public awareness is higher than ministerial action, and stressed that volatility in food systems is now the norm, driven by climate change, geopolitics, and rising costs, reports The Guardian.
Food Security as a National Security Concern
Richard Nugee, a retired general and signatory of the letter, described food security as a top-level national security issue. He warned that heatwaves in global grain-producing regions and disruptions from war could reduce supply to the UK, creating stress on households and supply chains. While civil unrest is unlikely, public frustration over rising food costs could have broader social consequences.
A partially published report from the UK’s spy chiefs also warned ministers that the collapse of key global ecosystems poses a national security risk, potentially triggering conflict, migration, and competition for resources. The Climate Change Committee recently advised that domestic food production should not fall below 60% of the UK’s needs, noting that climate-related damage could rise from £200 million today to over £2 billion a year by the 2030s.
Experts stress that without urgent action, Britain risks a deeper and more widespread food crisis, placing pressure on farmers, consumers, and national security alike.
