Sustainable Tourism – Promoting Environmental Public Health is an online course offered by the University of Copenhagen. This course introduces the key environmental health and natural resources management challenges associated with the rapid growth of international tourism arrivals in low-income countries. This will be done by focusing on the problems and potentials of tourism development in small island states in tropical and subtropical environments. This lecture will also present experiences and potential avenues to develop more sustainable tourism for these counties. This beginner level course takes 3 weeks to complete, with 2 to 3 hours per week dedicated to completing the modules. Each module consists of a series of videos, readings, and participation in discussions, in addition to graded assignments. Those who pass all graded assignments will complete the course.
