Sustainable tourism is an approach that takes into account economic, environmental, social and cultural aspects to minimize the negative impacts of tourism while increasing its benefits for local communities and the environment. The basic concept of sustainable tourism development is the main basis for achieving this sustainability goal. However, challenges in developing sustainable tourism, such as uncontrolled growth and conflicting interests, affect the implementation of these concepts. Best practices in sustainable tourism development also play an important role in reducing negative impacts and increasing the positive benefits of tourism. Therefore, this research identifies and analyzes the relationship between basic concepts, challenges and best practices in sustainable tourism development.
