Extreme weather conditions across Europe are continuing to exacerbate wildfire outbreaks and contribute to significant agricultural challenges, raising concerns about food security amid a prolonged drought.

In Greece, efforts to combat wildfires intensified as 10 water-dropping aircraft were deployed early Wednesday to support around 500 firefighters operating west of Athens. The operation comes a day after a fatal midair collision between two helicopters involved in the firefighting effort. The crew of one helicopter, comprising a Greek and a Danish national, died in the crash. The occupants of the second aircraft, a British and a Greek national, were hospitalized with reportedly minor injuries. Although winds fueling the flames subsided somewhat, authorities cautioned that high temperatures forecasted for the coming days continue to pose significant wildfire risks.

Italy has placed nearly all its cities under “red alert” for extreme heat, affecting both vulnerable groups and otherwise healthy individuals. The heat wave has also disrupted travel plans for hundreds of thousands of British tourists in the region. Meanwhile, French firefighters, including reinforcements from Ukraine, are working to extinguish remaining hotspots from the Gironde megafire, which scorched an area approximately four times the size of Paris. In Le Porge, near Bordeaux, firefighting operations are complicated by the discovery of unexploded World War II ordnance. The Netherlands is also battling a 21-hectare wildfire in the De Rosmolen reserve in Limburg.

In Central Europe, countries such as Hungary and Romania are contending with energy challenges after record low water levels in the Danube forced the shutdown of nuclear reactors that depend on river cooling, resulting in power cuts.

Amid these environmental stresses, farmers are warning that the drought may lead to food shortages. Tom Bradshaw, President of the National Farmers’ Union, emphasized the critical link between water security and food production, expressing concern about impending product shortages. Livestock farmers are reportedly using winter feed stocks earlier than usual due to insufficient grass growth. Crop production is also under pressure; potatoes, which rely heavily on irrigation, face significant yield reductions, while many arable farmers have expedited wheat harvests by several weeks—some marking the earliest in two decades—resulting in diminished yields.

Lincolnshire farmer Andrew Ward described the severe lack of rainfall, highlighting that his farm received only 4 millimeters of precipitation since mid-June and completed its wheat harvest a month ahead of schedule with lower than expected output. He warned of widespread wheat shortages across the country. Hydrology lecturer Dr. Anna Murgatroyd of Newcastle University projected potential increases in food prices and possible shortages of domestically produced items on supermarket shelves in the coming months.

The financial viability of farming has come under strain, exacerbated by rising costs for fertilisers and other inputs. This has led to an unprecedented surge in the number of farms being put up for sale. Bradshaw called for tax incentives to encourage farmers to develop onsite water storage infrastructure, noting that changing climates in other food-exporting countries could further impact supply chains.

Responding to concerns about food security, a spokesperson for the Prime Minister affirmed the government’s recognition of the issue as a matter of national security. The spokesperson highlighted ongoing collaboration with farmers, the Environment Agency, and water management sectors to address the effects of the dry weather. They also pointed to investments in long-term water resilience initiatives, including funding for nine new reservoirs, aimed at supporting farm water security and sustaining British food production.

Forecasts suggest central and southern England will continue experiencing high temperatures reaching 28 to 30 degrees Celsius before easing later in the week. While northern and western areas may receive some rainfall, the Met Office indicates that August is unlikely to bring sufficient sustained precipitation to alleviate drought conditions that currently affect all of Wales and half of England.
