Mass tourism has been recognized as a key factor in undesirable environmental and social impacts on host realms that work against sustainable development and involve negative impacts like environmental and social degradation, economic inflation and leakage, loss of habitats and wildlife species, and various social problems. The Panchase Region of Nepal needs to be developed as a model ecotourism destination with minimal impacts on ecosystem services, biodiversity loss, pollution, and climate change. ‘Nature-positive’ approaches not only halt the loss of ecosystems and the services they provide, but also assist in recovery and replenishment of ecological systems through participation and collaboration among different stakeholders at multiple dimensions leading up to end uses. This chapter will explore a sustainable tourism development model for the operation of an ecosystem restoration-oriented private tourism business in the Panchase region. Key informant interviews, consultations, and focus group discussions on the nature-positive approach were conducted. The pristine landscape of the Panchase mountain region supplemented by the World Peace Biodiversity Park has attracted more visitors for trekking and homestays, which has placed tourism development on the verge of exploiting the natural environment and resources. Good governance practices can be replicated for private sector tourism with socially and ecologically balanced sustainable tourism approaches that are nature-positive and embody principles of ecotourism and socio-ecological production landscapes (SEPLs). Integration of these approaches will create a positive environment for sustainable tourism development and tourism entrepreneurs such as Back to Nature, leading to the utmost preservation and protection of critical habitats in the Panchase Region of Nepal.
