The other reality is that in a modern context the greatest threat to food security is probably a global one. We have a rapidly growing population, set to reach 9 billion by 2050, and we have the countervailing force of climate change and a lack of water resources, which means that in parts of the world where we are currently producing food it may be more difficult to do so in 10 or 15 years’ time. Scarcity of water could be a global challenge. The issue of food security is less about national self-sufficiency in case there is another world war—our negotiations with the EU are challenging but we do not envisage it getting to the state of our requiring something like the Emergency Powers (Defence) Act 1939. The challenge on food security, insofar as it exists, is ensuring that we can feed the world.
