The UK Food Imports Most at Risk from ‘El Nino’ Heat Stress This Summer
The UK food imports most at risk – Climate change is intensifying its grip on global food supply chains, with UK imports of critical staples now under significant threat. A recent report highlights that agricultural workers in developing nations, who supply essential goods like rice, coffee, and tea, are increasingly unable to sustain their work due to extreme heat conditions. This trend, driven by rising global temperatures, could disrupt food availability and pricing for British consumers, according to experts.
Heat Stress and Agricultural Challenges
The Energy and Climate Intelligence Unit (ECIU) conducted an analysis revealing the growing strain on food production in regions already vulnerable to climate extremes. Farmers cultivating key products such as rice, coffee, and cocoa are facing unprecedented difficulties as heat stress becomes more frequent and severe. These conditions are not only affecting crop yields but also the ability of laborers to work efficiently, leading to broader implications for food security.
With the likelihood of a warming “El Nino” weather event reaching 80% this summer, the situation is expected to worsen. Scientists warn that 2027 may become the hottest year on record, exacerbating existing challenges for agricultural workers. This scenario poses a dual threat: to the crops themselves and to the human labor force that sustains global food systems.
Impact on UK Imports and Economic Costs
According to the ECIU, developing countries account for 13% of the UK’s food imports, valued at £8.9 billion in 2025. Among the 15 largest suppliers from these nations, they contribute £7.4 billion annually to the UK’s food supply. This includes vital products like rice from India, bananas from Colombia and Ecuador, and tea from Kenya. However, the data also shows that heat stress has already begun to impact these supply chains significantly.
In 2024 alone, agricultural workers in these 15 countries lost 216 billion potential work hours due to extreme heat. This equates to nearly 49 days of labor per worker each year, highlighting the scale of disruption. The report further indicates that these losses could increase by four to five hours per worker annually, compounding the challenges faced by farmers in the coming years.
Global Work Hour Losses and Climate Trends
The ECIU cited research from the Lancet Countdown, which found that 640 billion potential work hours were lost worldwide in 2024 due to heat exposure. This represents a staggering increase from previous years, with losses surpassing the highest recorded before and nearly tripling the average from the 1990–1999 decade. Agricultural workers are the most affected group, with nearly two-thirds of all lost work hours attributed to their sector. In poorer countries, the proportion rises to 75.5%, underscoring the disproportionate impact of climate change on vulnerable populations.
Shamika Mone, a rice farmer from India and president of the Intercontinental Network of Organic Farmers, emphasized the severity of the situation. “Extreme heat makes the already difficult job of farming even harder,” she stated. “There are real fears that hotter, drier weather caused by a super El Nino could damage harvests. To safeguard our food system, governments must cut greenhouse gas emissions, including those from fertilizer production, and provide direct climate finance to smallholders. Nature-friendly farming methods, like crop diversification and shade tree planting, can help cool farms and protect both workers and crops.”
Broader Implications and Systemic Risks
The ECIU report aligns with warnings from UK intelligence officials, who noted that biodiversity loss and ecosystem collapse could trigger a global scramble for resources. This scenario might lead to mass migration toward the UK and even escalate to nuclear conflict in Asia. The Institute and Faculty of Actuaries (IFOA) also raised concerns in April, stating that worsening climate impacts and the decline of natural ecosystems are causing the world’s food system to fracture.
Gareth Redmond-King, head of the ECIU’s international programme, warned of the compounded risks. “Climate change is hitting food crops directly, but it’s also affecting the workers who grow them. With a powerful El Nino looming, unless farmers in the UK and their international counterparts shift toward more resilient and sustainable practices, food security for all will be jeopardized.”
Domestic and International Food System Strains
Previous studies by the ECIU have shown that climate impacts have already added approximately £360 to the average UK household food bill each year. This financial burden is reflected in the country’s own agricultural challenges, as UK farmers have experienced three of the worst harvests on record in the past five years. The combination of domestic and international pressures suggests a critical moment for the food system, where both production and distribution face increasing strain.
Experts stress that the effects of climate change are not limited to specific regions. The loss of work hours in key supplier nations directly translates to reduced food availability for the UK. As these countries struggle with heat stress, the ripple effects could lead to higher import costs, inflationary pressures, and a potential crisis in the supply of staple foods. The interconnected nature of global agriculture means that disruptions in one part of the system can have far-reaching consequences elsewhere.
For instance, the loss of 216 billion work hours in 2024 has already impacted the production of essential goods. Rice, a primary import from India, is particularly vulnerable. Similarly, fruit crops like grapes, lemons, and oranges from South Africa, Peru, and Egypt are at risk. Coffee from Vietnam and Brazil, and cocoa beans from Côte d’Ivoire and Ghana, also face potential setbacks. These losses could lead to shortages, higher prices, and a greater dependence on fewer suppliers, increasing the vulnerability of the UK’s food system.
Call to Action for Sustainable Practices
Redmond-King and other analysts advocate for urgent action to address these challenges. They argue that transitioning to resilient and sustainable agricultural methods is essential for long-term food security. This includes investing in climate-smart technologies, improving irrigation systems, and supporting small-scale farmers with resources to adapt to changing conditions.
“We need to support farmers both locally and globally to adopt practices that reduce their exposure to extreme weather,” Redmond-King added. “This means not only cutting emissions but also ensuring that climate finance reaches those most in need.” The ECIU’s findings serve as a stark reminder of the need for coordinated efforts to mitigate the effects of climate change on food production and distribution.
As the summer approaches, the potential for an El Nino event adds to the urgency. With record-breaking temperatures already being observed, the combination of climate change and El Nino could create a perfect storm for global food systems. The UK’s reliance on imports from countries struggling with heat stress means that any further disruption could have serious consequences for domestic food availability and affordability.
Experts warn that without immediate action, the impact of climate change on food production will continue to grow. The ECIU’s report underscores the importance of addressing both environmental and social factors in agriculture. By supporting sustainable practices and ensuring climate finance reaches vulnerable communities, there is hope to stabilize the food system and reduce the risks posed by extreme weather events.
