The Weather Is Changing. Britain’s Food Policy Has Not

Britain’s food system rests on a fragile assumption. Water will be there when farmers need it.

Recent heatwaves and drought exposed the weakness in that assumption. Smaller yields, earlier harvests, and higher prices are the immediate consequences. The bigger issue is whether Britain has the water infrastructure to produce food reliably.

The message from the National Farmers’ Union is clear:

‘Water security is food security. Food security is national security.’

Eight days above 34°C. That broke records set in 1976 and 2020. Rain vanished. Just 21.3mm fell by July 26, following 90.4mm in June. For farmers, heat and drought collide. Crops need water while rivers run dry. The Environment Agency slapped 1,353

restrictions on abstraction licences in a single week.

This exposes a policy contradiction. The country wants more domestic food production. Yet it lacks a water system to support agriculture through volatile weather.

When British production falls, imports provide a safety valve. But that safety valve fails when extreme heat hits other European regions at the same time. Britain cannot assume food will always be available or affordable elsewhere.

The answer is not to grow every crop domestically regardless of cost or climate. But we cannot separate food security from water security.

Britain needs a long-term agricultural water strategy. We need more storage, smarter irrigation, greater efficiency, and clearer decisions about what makes economic and environmental sense to grow here.

Farmers cannot carry the cost alone. Government cannot ask households to conserve water while treating agricultural demand as an afterthought. The traditional British dinner is unlikely to disappear. But what is on the plate will depend on decisions made months earlier about water, climate, and supply risk.

This summer is a warning, not an aberration. Britain’s food system was designed for a climate that no longer exists. Its approach to water matches that old climate.

The first problem is already changing.

The second needs to catch up.

Water security is food security.
