Lesson FS4: Food Security as a System

Description: 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.

Objectives

What Students Learn:

  • Students learn the 14 habits of a systems thinker and the 6 steps used to analyze systems, along with strategies for illustrating systems.
  • They identify interactions in the food security system as well as the “tipping points” that lead to irreversible change.

What Students Do:

  • Students relate systems thinking habits to everyday situations,
  • use a variety of diagrams to visualize systems,
  • work collaboratively to create a large causal loop diagram of food security, and
  • evaluate the stability of our food production system by assessing interactions, feedback loops, and tipping points.

THE BIGGER PICTURE

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.
