A food policy expert, Professor Tim Lang, is urging the UK government to stockpile food due to the nation's vulnerability to climate shocks and wars. Lang argues the UK's low food self-sufficiency (54%) compared to other developed nations makes it susceptible to supply disruptions. He highlights that other countries, like Switzerland, maintain emergency stockpiles, while the UK advises households to keep only three days' worth of food. Lang's concerns are echoed by experts who warn that a food supply shock could trigger social unrest. Despite declining domestic food production, the UK government has no plans to increase self-sufficiency or set production targets.
