The environmental sustainability of ecotourism based on the status of waste management. Local people and leaders of community based organizations mentioned that effective management of waste and sewage required a lot of initial investment, which was beyond their capability. According to them, although there is a policy to develop Phang Nga Bay as a destination for ecotourists, neither the central nor the provincial government has provided any budget for management of solid waste and sewage. With regard to solid waste, the municipality undertakes waste collection only in its area of jurisdiction. It is only in the municipality area that the waste is collected and transferred to an open dumping site located at the back of the District Office near the sea. The collected waste is then transported to a very small dumping facility provided by the municipality near to its premises.
