Supply chains and other trade networks are of interest to geographers, due to their ability to connect economic processes at various scales. Relatively recent research, however, suggests that core concepts and topics in economic geography are not being fully and effectively engaged in the classroom environment. With such findings as a motivation, this article explores the integration of an online case study on the geographies of supply chains and their vulnerability to natural disasters into introductory human geography and world regional geography courses. Post-lesson survey results intimate that there are differences between the two courses with respect to understanding some economic geography concepts but relative agreement in interpreting how regionalized natural phenomena can disrupt international business networks.
