INTRODUCTION The definition of pro-poor tourism is referred as positioning of tourism growth to produce livelihood opportunities between tourism and impoverished people (Mowforth and Munt, 2016). Pro-poor tourism is an approach and it is not a type of tourism or product (Ashley et al., 2000). However, any type and size of tourism business such as volunteer tourism, philanthropic tourism, community-based tourism, cultural tourism, eco-tourism, rural tourism, responsible tourism, urban tourism, sustainable tourism, homestay, bed and breakfast, an urban hotel, tour operator, food and beverage provider, souvenir outlet and infrastructure developer can be categorized under pro-poor tourism (Mitchell and Ashley, 2010). Even though there are several types of tourism under the pro-poor tourism approach, the only objective pro-poor tourism has is to contribute the benefits perceived through tourism to the local community at any tourist destination. Therefore, capacity building, stakeholders' support, and infrastructure development plays an important role in increasing local peoples' well-being.
