Fire lines as fault lines: Increased trade barriers during the COVID-19 pandemic further shatter the global food system

In this opinion piece, we highlight that trade barriers established during COVID-19 as “fire lines” to prevent cross-border transmission of the pandemic could become “fault lines” that demolish the global food system.
