Sustainable tourism classes are a great area of study for students interested in travel and hospitality, as well as community development and economic growth. A sub-field of one of the fastest growing industries, sustainable tourism frequently focuses on creating long-term benefits for travel within local economies.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.
