For the Instructor
These student materials complement the Future of Food Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

A good way to understand the complexity of different types of food systems is to look for organizing principles to classify them. In the introductory food supply chain exercise at the beginning of this module, if you chose a product that was produced a long distance from where you consumed it, you are aware that the global food system today handles food at an enormous spatial scale. This example leads to one way to organize our understanding of food systems, which is the hierarchy global, regional, and local scales of food systems (Fig. 10.1.4).

Another helpful way to classify food systems is to look for typologies of food systems. Building typologies is a somewhat subjective but often helpful process where we look for groups of systems or components that hang together in order to better understand their function, importance, or other attributes. For the typology of food systems we present here, we are thinking about classifying food systems based on how production occurs and at what scale, which portions of society are involved in production and distribution, and the rationale underlying production, distribution, and consumption. In this course, we use the scheme of three overlapping food systems that exist at global, regional, and local scales shown below in Fig. 10.1.5.
