Addressing the threats to tourism sustainability using systems thinking: a case study of Cat Ba Island, Vietnam

摘要

Tourism is a dynamically complex system. Planning for sustainability is therefore difficult because past system behaviour is often not a good indicator of future behaviour. Despite this, tourism planning is mainly based on forecasting methods that rely on historical data to predict future trends with the assumption that tomorrow's world will be much like today's. To properly manage dynamically complex systems it is necessary to understand the underlying system structures that influence current as well as future system behaviour. This is the domain of systems thinking, which is not a forecasting method, rather a method used to understand the feedback mechanisms that influence system behaviour over time. This study describes the link between tourism development and systems thinking theory, and uses this to identify underlying systems structures likely to influence tourism development and sustainability within Cat Ba Island, Vietnam. We show that current policies promoting rapid tourism growth on Cat Ba Island are likely to be fixes that fail due to unintended consequences that ultimately undermine sustainability. To ensure sustainability, the policy focus must switch from growth to planning for limits to growth before tourism carrying capacity is undermined, which could ultimately lead to tourism decline.
