A food system encompasses all the processes involved in producing, processing, distributing, and consuming food. It includes everything from agriculture and fishing to food processing and retail. Each step in the food system affects the quality, availability, and sustainability of food, influencing both human health and the environment. Food systems also involve the social and economic aspects of food, such as food security, nutrition, and food policy. They connect farmers, consumers, and businesses, highlighting the importance of local and global networks. Understanding food systems helps identify challenges and opportunities for improving food access and sustainability.
