Abstract
The objectives of this study were to investigate the economic value of watershed management and analyze the factors that influence the decision making in watershed management services. The contingent valuation method (CVM) was used to estimate the economic value of natural resources in terms of public goods. The data was collected during October-December 2018 based on the samples taken from the upper Prachin Buri watershed (UPBW). The samples were divided into people who live in the upper and lower parts of the selected watershed. Four hundred and three respondents were interviewed using open-ended questions to inquire about the willingness to pay (WTP) by the respondents in the lower part and the willingness to accept (WTA) by the respondents in the upper part of the watershed, by using the assumptions obtained from the hydrological model (SWAT model). This was done by stipulating a situation of land use change as the information used in decision-making by the respondents, based on the strategy of payment for watershed management services. Using the logistic regression analysis, which analyzes the relationship between the dependent and independent variables of WTP (200 people) and WTA (203 people), we found that 66.5 percent of the people residing in the lower part of the watershed were willing to pay, while the rest were unwilling to pay for the services. For the people living in the upper part of watershed, 60.1 percent were willing to accept and 39.9 percent were unwilling to accept the dues for the services. The results from the analysis indicate that the relationship between socioeconomic factors, including gender, age, education, residence, career and income, and the willingness to pay and to accept, were not related at a significance level of 95%.
