"“Supermarkets are very efficient at providing a lot of food for a lot of people but they have their vulnerabilities,” says Moya Kneafsey, professor in food and local development at Coventry University. In Britain, for example, only 17% of fruit and half of vegetables are grown locally – the rest comes from cheap international trade, as supermarkets promote year-round availability. “Covid-19 begs the question – will the imports we rely on be dependable in the future? Even if supply is OK at the moment, will it be affected by the long-term impact of the virus in producer countries and in the transport sector?”"
