Valuation of the Trang An karst system using contingent valuation method and choice experiment

A new valuation of the Trang An karst system reveals its economic worth to be between 125 and 133 million USD annually, with potential to increase fivefold under improved conservation scenarios. The study combines Contingent Valuation Method (CVM) and Choice Experiment (CE) to assess the site's value while considering threats like urbanization. Findings highlight the critical role of sustainable development in preservation, emphasizing green planning and smart models using big data to mitigate environmental impacts. This approach sets a precedent for evaluating heritage sites by integrating economic, cultural, and ecological factors.
