The Food and Agriculture Organization of the United Nations defines a food system as the entire range of stakeholders and their interlinked valueadding activities involved in the production, distribution and aggregation, processing, marketing, consumption and waste management of food products that originate from agriculture, forestry, and parts of the broader economic, societal and natural environments in which they are embedded (Take and Systems 2015). To be considered sustainable, a food system must deliver food security and nutrition for all in such a way that the economic, social, and environmental bases to generate food security and nutrition for future generations are not compromised (Bassarab et al. 2019; FAO 2017; FAO et al. 2018). A sustainable food system lies at the heart of the United Nations' Sustainable Development Goals (SDGs).
