Tourism is recognized as one of the largest and fastest growing sectors, regarded for its highly contributing role in the global and national economy. In addition to the economic importance of tourism, it also has an impact and contribution on society, culture and the natural environment. This contribution of tourism to the economic, socio-cultural and natural environment can be seen in two ways, both positive and negative. In order to achieve or maximize the positive contribution of tourism and at the same time minimize its negative impact or otherwise maximize the benefits of tourism while minimizing its costs to the economy, society, its culture and the natural environment is a big challenge to be faced by the global tourism industry. while tourism's contribution to cultural reinvigoration, its conservation, protection, revitalization and creation of a feeling of pride among locals for its culture, etc., can be seen as an important socio-cultural benefit.
