The COVID-19 pandemic hit the food supply chains hard, especially in urban areas where inhabitants mostly depend on market-based food systems. Despite the intended exemptions made for food transport reality shows different in that the imposed mobility restrictions by COVID-19 prevention measures interrupted both agricultural and food supply chains.
