Feeding the World and the Role of Vertical Farming
In 2017, the United Nations (UN) Department of Economic and Social Affairs reviewed global demographic trends and concluded a forecast of the world population to reach 9.8 billion in 2050. The outlook on an increase in population of approximately 2.2 billion in 13 years has, together with sustainability concerns on our global food system, opened up many discussions on food security. Food security is defined as a state “when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food which meets their dietary needs and food preferences for an active and healthy life” (FAO, 1996). In this context, the prevalent food system, criticized for its damaging impact on the environment and high energy consumption, is increasingly put into question for being capable of addressing contemporary challenges of climate change and population growth.
