Britain's scorched fields mean a food crisis – and the government is ignoring the one measure that would help | George Monbiot

This summer’s extreme weather and wars in Iran and Ukraine have made our need for food stockpiles more pressing than ever

When a business makes long-term plans, they call it prudence. When a government makes long-term plans, they call it communism. Any sustained state intervention attracts the prefix “Soviet-style”, and triggers vicious attacks across the billionaire media. So governments have developed a bias against long-term thinking. This may explain why we no longer maintain strategic food reserves.

In Britain, where soils have parched, market analysts warn that we’re facing the most severe food security crisis in decades. In normal years, crop failures at home don’t threaten our security, thanks to global trade. This is one of the reasons why hunger and famines are rarer and less deadly than they used to be. But this is not a normal year, because the problem is now global.
