The COVID-19 emergency has revealed the extreme fragility of large cities to unexpected complex global risks and crises. City lockdown has led to increasing awareness of the vital importance of food availability for citizens.
The combined effect of border closure and movement restrictions increased food losses and export costs, especially for vegetables and perishable goods exposing non-self-sufficient countries.
A recent study claims that urban agriculture in developed countries should be fostered with emerging growing practices and edible green infrastructures, such as vertical farming, hydroponics, aeroponic, aquaponic, and rooftop greenhouses.
Notwithstanding the limitations of traditional urban farming activities, innovative and disruptive solutions and short food supply chains of fresh agricultural products might play a positive role in lessening uncertainties from global systemic risks.
