Lesson FS4: Food Security as a System


The goal of this lesson is to encourage students to look at the topic of food security using a systems approach, and to evaluate the stability of our global food production by assessing the interactions within the system. Students will review the definition of a system and discuss how approaching a problem or issue by modeling it as a system can lead to both improved understanding and more effective problem-solving. The lesson includes an overview of different methods used to visually represent systems-level problems, and students practice using these models to illustrate food security. Students will ultimately apply their knowledge of the concept of food security and the stakeholders involved to create a large causal loop diagram that helps them visualize interactions within the system, feedback loops, and tipping points. This activity will help students evaluate the sustainability of our food supply and the vulnerability of particular groups to food insecurity.
