Agro-food system is not a freąuently used term. A great majority of both researchers and practicians when talking about agriculture concentrate only on a part of an agro-food system, such as production or distribution of goods. This article presents recent changes that have occurred in agro-food systems, considered as complex networks of mutually interrelated players, and challenges with which they have to cope. Moreover, it also acąuaints the reader with the concept of knowledge management and its applicability in agro-food systems.
