The president of the National Farmers' Union, Tom Bradshaw, warned on 2 August 2026 that Britain could face shortages of certain foods as parts of England endure a severe drought, urging the prime minister to intervene. His alert follows a winter of floods that disrupted planting, a spring and summer of dry conditions that have limited irrigation, and what farming groups describe as the third drought in five years — a pattern they call the "new normal" for British agriculture (The Guardian).

The Met Office recorded just 8% of England's average rainfall for July 2026, a figure likely to be confirmed as the driest July on record. The scale of domestic water stress is visible in everyday restrictions: approximately 23 million people across England and Wales were under a hosepipe ban by late July (The Guardian). A hosepipe ban is a legal restriction that prevents households from using hosepipes for activities like watering gardens or washing cars, imposed by water companies during shortages. The UK Health Security Agency issued heat-health alerts for eight regions of England, with amber alerts for four regions and yellow alerts for four others, running from 9am on 3 August to 9am on 5 August.

In the fields, the consequences are already measurable. The Agriculture and Horticulture Development Board (AHDB), a levy-funded body that supports British farming, published its first Harvest Report of 2026 and found that hot weather produced the earliest harvest since its records began in 2006. Many farmers in the south and east of England completed harvest two to three weeks ahead of the long-term average. Wheat farmers reported crops at half their normal height. Anthony Hopkins, AHDB's director of cereals and oilseeds, said cereal yields had generally been below the 10-year average so far, with some farms experiencing significant reductions (The Guardian). One NFU chairman reported his farm was "30% down," producing 800 tonnes less than normal (BBC).

Farmers in parts of England and Wales have described reduced yields, forced early harvesting, and an increase in field fires (BBC). The dry conditions also fuelled wildfires across the UK, most recently near the Sizewell nuclear plant and Dunwich Heath in Suffolk (The Guardian).

Bradshaw, speaking to BBC Radio 4, called for farmers to receive tax breaks to build on-farm water storage systems, positioning reservoir infrastructure as a necessary adaptation for coming years. The NFU has published dry-weather guidance noting that short-term options exist to improve farmers' access to water outside their licence conditions during prolonged dry spells and drought (NFU). The Environment Agency, separately, has urged farmers to conserve water, noting that spray irrigation faces increasing pressure as river and groundwater levels fall (NFU).

The 2026 crisis does not arrive in isolation. The NFU warned in March that food prices were likely to rise due to the Iran war and that continued drought could cause shortages of some foods (BBC). A Reuters analysis published in June 2026 argued that farmers were likely to apply less fertiliser than usual, which could reduce yields further and lead to acute food shortages later in the year (Reuters). The FAO (the Food and Agriculture Organization, a UN agency that tracks global food production) has observed that past El Niños have brought failed harvests, food shortages, and pressure on global markets, with El Niño-related losses likely to begin manifesting. El Niño is a recurring climate pattern in the Pacific Ocean that shifts weather systems worldwide, often causing drought in some regions and flooding in others (Reuters). Reuters also reported in June 2026 that fertiliser shortages, inflation, and rising oil prices could push an already fragile food industry to the brink (Reuters).

The livestock sector has its own accumulating pressure. Drought conditions in the previous year led farmers to rely more heavily on concentrated feed in place of grazing, driving up milk production costs (Reuters). In August 2025, Reuters reported that drought left UK beef farmers scrambling to feed hungry herds, with the Met Office saying summer 2025 was set to be the UK's warmest on record (Reuters).

The broader context here is that the convergence of domestic crop failure, global supply-chain stress from geopolitical conflict, and cyclical climate phenomena like El Niño creates a compounding risk environment that no single policy lever can address. The NFU's ask for tax breaks on reservoir infrastructure is an adaptation measure, not a crisis response; it would take years to commission and fill new storage. In the near term, the question is whether the government treats domestic food production as a strategic priority worthy of emergency intervention or leaves farmers to absorb losses that will pass through to retail shelves. The NFU's language has sharpened over time, from warnings about price rises in March to Bradshaw's direct appeal to the prime minister in August. Whether that escalation prompts action from Downing Street will determine how much of the 2026 harvest shortfall translates into visible consumer shortages.
