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.
