Willingness to Pay for Whale Shark Conservation in Sorsogon, Philippines

  • Anabeth L. IndabEmail author


This study estimated the willingness to pay (WTP) of Sorsogon residents to preserve the continuous presence of whale sharks by using the contingent valuation methodology (CVM). CVM is a method for estimating the monetary value that a person places on a good or service that is not normally sold in markets. The approach directly asks people if they are willing to pay for the good rather than inferring this from observed behavior. Using the drop-off survey method, this study achieved a response rate of 98 %; out of the 600 questionnaires distributed, 588 usable questionnaires were retrieved. The results showed that Sorsogon residents had low positive WTP, which ranged from PHP 17 (USD 0.34) to PHP 35 (USD 0.70) per household per month. Furthermore, more than half of the respondents (60.71 %) strongly agreed that everyone is responsible for ensuring that plants and animals—as they are known today—will exist for mankind in the future. This suggests that the respondents hold a perceived bequest value. Overall, the survey results show that people are aware and concerned about environmental issues, including the precarious condition of whale sharks in Sorsogon. They are not, however, able or willing to pay for the implementation of a conservation program due to poverty, employment, and other economic concerns taking precedence over environmental issues.
