After World War II there was a necessary focus on food security in Britain, informed by ration books and virtual bankruptcy of the country. But we forget quite quickly and the National Farmers Union reported that self-sufficiency levels in fruit & vegetables fell steadily since the mid-1980s, from 78% to 64%. Britain imports 46% of its food and this may explain why our Government has delayed Brexit border checks five times since 2020 for fear of food shortages and, ultimately, food fighters. Our lack of resilience is not a sustainable position, particularly for a nation that is now isolated from the safety of belonging to the biggest trading bloc in the world. We also operate in a world where food and water will become precious assets into the 21st Century due to global warming.
