Food systems refer to the entire process of producing, processing, distributing, and consuming food. This includes all activities and resources involved in the production of food, from agriculture and fishing to food manufacturing and retail. Food systems also encompass the social, economic, and environmental factors that influence food production and consumption. Research in the area of food systems focuses on understanding and improving the sustainability, efficiency, and resilience of food production and distribution. This includes studying the impact of various factors such as climate change, land use, food waste, and food security on food systems. Researchers also look at ways to promote healthier and more equitable food systems by encouraging sustainable agricultural practices, supporting local food systems, and ensuring access to nutritious and affordable food for all.
