I'm hoping to better understand the efforts to promote sustainable tourism in Asia's natural landscapes, and I'm looking for advice from other forum users. What initiatives have been taken to develop sustainable tourism in Asia, and how successful have those initiatives been? What challenges are currently facing sustainable tourism in Asia, and what are potential solutions to address those challenges? Are there any specific examples of successful sustainable tourism initiatives in Asia that could be used as a model for other countries or regions? Any information or advice would be greatly appreciated.
