Introduction
Due to rapid urbanization, population growth, climate change and environmental pollution, food security and sustainability have become a primary concern that needs to be addressed globally. According to an estimate conducted by the United Nations Department, the world population is expected to reach 9.7 billion in 2050, and a third of the world population is expected to live in cities with at least 2 million inhabitants. The recent COVID-19 pandemic has had an impact on food supply by disrupting the food supply chain and consequently also the further increase in prices. From these circumstances emerged the exigency and the need to cover the food supply with local products. Furthermore, the growing concern about the effects of environmental pollution and the intensive use of agricultural land with pesticides and chemical compounds, the consumer is inclined to choose healthy, fresh and traceable food products.
The interest in urban agriculture already present in recent times has strengthened during the pandemic which, globally, has triggered food insecurity.
