Communication is used to engage and involve students in addressing food deserts and developing sustainable solutions. This application-based activity allows students to explain the reality of food deserts, map the food deserts in an area of interest, develop an intervention, and present their communication intervention to a nonprofit interlocutor. The goals of this unit activity are to guide students along the research process, argument formation, and advocacy-centered presentations for the marginalized group's access to affordable healthy food options. Courses: This activity is great for high school and college students in classes such as Public Speaking, Health Communication, Rhetoric of Critical Health, and Environmental Communication. Objectives: By the end of this activity, students will be able to: (1) visualize and communicate disparities within food deserts; (2) develop community-engaged and advocacy-oriented presentations; and (3) distinguish key factors differentiating food availability utilizing mapping techniques.
