Climate change is putting the UK's food security at risk, with experts warning of potential shortages and price hikes in the coming years.

The UK’s food security is under serious threat due to the escalating impacts of climate change. As extreme weather events become more frequent and intense, the nation’s ability to produce and supply food is being challenged like never before.
Professor Paul Behrens from the University of Oxford has raised the alarm, stating that the UK is on the brink of a food security crisis. His warnings come as the country experiences record-breaking heatwaves and other extreme weather conditions.
Extreme Weather and Agricultural Struggles
Farmers across the UK are grappling with a relentless cycle of extreme weather events, including heavy rain, heatwaves, droughts, and storms. These conditions are significantly affecting food production and agricultural practices.
“Farmers are dealing with an endless sequence of extreme weather events, which is impacting how we grow food,” Mr.
Behrens explained. “We’ve seen crop yields stagnate and then decline. Farmers are struggling to feed livestock during floods, as animals cannot graze and must be fed stored food.”
The situation is critical, with the tipping point potentially arriving within a couple of years. The most vulnerable populations will be the first to feel the impact.
Harvest Failures and Food Price Increases
A report from the Energy and Climate Intelligence Unit highlights the severity of the issue. It reveals that three of the five worst cereals and oilseed harvests on record in England have occurred this decade, largely due to extreme weather.
The think tank also found that a third of food price increases in 2026 were driven by climate change. Professor Behrens noted that foods like corn, beef, olive oil, cocoa, and coffee are already affected, with climate change expected to inflate the prices of all foods eventually.
“We need to be eating more plants, not just for climate change mitigation but also for resilience,” he emphasized. “We need to reduce our waste, improve our productivity, and implement food resilience policies at local, regional, and national levels.”
Government Response and Future Plans
The Department for Environment, Food and Rural Affairs has outlined a plan to support British farmers and enhance food security. This includes investing £53 million in the farming innovation programme, bringing total funding for this year to £123 million. The funds will support robotics, soil health, and water management.
The government also plans to collaborate with the industry to develop sector growth plans in areas such as horticulture and poultry. Additionally, efforts will be made to cut EU trade friction hampering exports with a new deal with the bloc.
The UK currently produces around 65% of the food consumed by Britons, with international trade supplementing domestic production to strengthen food security against risks like adverse weather and disease.
Paul Tompkins, deputy president of the National Farmers’ Union, highlighted the increasing frequency and severity of extreme weather events. “Fields that produce wheat for the nation’s bread can be underwater one year, then parched and cracking the next. Livestock fields swing from flooding to scorching conditions with little grass growth to feed the cows and sheep that make our landscape,” he said.
Professor Hayley Fowler from Newcastle University emphasized the need for rapid action. “During the heatwave of 1976, few remember the summer’s failed harvests, rising food prices, extensive wildfires, and the heat-related illness and death suffered by many. On the 50th anniversary of this iconic event, we are showing the public that these impacts will become part of normal life in the coming decades if we don’t rapidly reduce fossil fuel emissions and adapt our schools, homes, hospitals, and workplaces to cope with the extreme heatwaves we face.”
