Exploring World Agriculture is a course that allows students to learn about the agriculture of a specific location. The course identifies a geographic location and then investigates and researches the crop, livestock, food production, and related factors of that area. History, culture and political impacts are presented. The course invites OSU and community members with expertise in the selected geographic location to instruct the class.
