An Economic Analysis of Coral Reefs in the Andaman Sea of Thailand

The focus of this study is the valuation of coral reefs and how this information can be used to improve planning for coral reef management in Thailand. The site analysed, Phi Phi Islands, is rich in reef systems and is envisioned as an eco-tourism destination by government planners. Phi Phi can generate large economic values through recreation. The consumer surplus estimated by the travel cost method reveals an annual value of 8,216.4 million Baht (US$205.41 million). This study also utilised the contingent valuation method to estimate both the use and non-use values of Phi Phi’s coral reefs, representing an annual value of 19,895 million Baht (US$497.38 million). It is apparent from this analysis that both local and national levels of government in Thailand can justify larger annual budget allocations for managing coastal resources. At present, the economic benefits from coastal resource management in Phi Phi are mostly due to the local residents and businesses. One of the economic instrument options to capture the net benefit values of Phi Phi is to directly target the consumers. Tourists could be charged fees for physically using the environment, such as participating in offshore water sports (specifically including snorkelling boats and dive operations), swimming and beach activities. The contingent valuation method provided information regarding the extent of the domestic consumer surplus. It estimated the consumer’s willingness to pay to increase biodiversity at Phi Phi as 287 Baht (US$7.18) per visit.
