The impact of extreme heat on yield in the UK: the situation at Diddly Squat Farm

Jeremy Clarkson, owner of Diddly Squat Farm in Oxfordshire, described the state of his harvest as critical against the backdrop of the hot weather settled in the region. The weather forecast for Chipping Norton suggests temperatures rising to 33°C, while in a number of other parts of the country thermometers may reach 36°C. Earlier in July, the Meteorological Office recorded record-low rainfall in England and Wales.

The National Farmers' Union (NFU) has expressed concern over a potential food shortage amidst the prolonged dry period. The organization's president, Tom Bradshaw, noted that the drying out of the soil due to the extreme heat is negatively affecting production volumes. Proposals have been made by the industry community to introduce tax incentives for farmers investing in water storage systems to increase farm resilience to climate change.

British farmers are facing complex production difficulties: the past winter was accompanied by severe flooding that complicated sowing, while the subsequent drought and water usage restrictions exacerbated the situation. Wheat producers report that the current harvest is significantly below average in stem height, which led to the earliest harvesting campaign in recorded history.

The economic efficiency of farming remains a complex issue. Jeremy Clarkson previously reported that he intentionally left 200 acres of land uncultivated this year, as sowing wheat or barley under the current conditions guaranteed financial losses. The owner of Diddly Squat emphasized that making a profit from food production is becoming almost impossible, which may force farmers to look for alternative ways to use their land plots.

According to reported data, between 2023 and 2024, the farm's profit amounted to less than 15,000 pounds sterling, and in 2024–2025 the farm incurred losses of 5,000 pounds sterling. Clarkson previously noted that profitability indicators in the sector often do not reach the level of the minimum wage despite significant labor inputs.
