As borders harden during pandemic, some countries look to hold on to their own food (Washington Post)

A steady rise in countries limiting or banning food exports has triggered warnings about possible disruptions to the global food supply as the world retrenches amid the coronavirus pandemic. Senior Research Fellow David Laborde stated there is no crisis yet, with global food stocks relatively high, but the danger of a handful of nations imposing export quotas or moratoriums has a cascading effect that could clog global markets.
