Tourism, as a tool of community development, has been utilised in Indonesia since the early development of protected areas. On the island of Lombok, Gunung Rinjani National Park (GRNP), the private sector businesses in major are involved in trekking, which is the only tourism product developed inside the park. However, the benefits arising from tourism in GRNP have not reached many of the poor living in the surrounding areas of the park, and tourism contributions to conservation of the natural resources have not been maximised. This book seeks to find out more about private sector roles and involvement in development, through research on trekking businesses operating in GRNP. Thus, the main research question explored is: How can Lombok trekking organisers deliver more benefits to the conservation of Gunung Rinjani National Park (GRNP) and local community development?
