The case for farming subsidies after Brexit | Letters

George Monbiot makes many good points (Farmers fear life outside the EU, but it could mean a rebirth for rural Britain, 11 January), including free markets' impact on small farmers whose incomes fall in times of plenty. He could have said more on food security. Climate change, including gas escapes from frozen deposits, is a growing threat but pests, diseases, routine weather and even large volcanic eruptions (eg Tambora, 1815) can create havoc. So who is actually responsible for food security, here or abroad?

"Britain can always import" is the reply despite a falling pound, but a recent Russian drought caused a grain export ban which could spread if global supplies struggled. Fisheries are exhausted, good British land is vanishing under development, yet nobody wants the bill for food storage. Instead surplus food yields quick profits via livestock feed, biofuels, brewing or even cosmetics.
