The COVID pandemic has shown the fragility of our global food supply chains, with many supermarkets and restaurants in almost every country having experienced food shortages. Millions of people in the UK alone have experienced severe food insecurity during COVID-19, according to a recent report by the country’s Foods Standards Agency. But food shortages were prevalent long before the pandemic.

At the same time, one-third of all food produced each year is squandered or spoiled before it can be consumed. Research also suggests that high-income countries waste as much food as sub-Saharan Africa produces.
