Valuation of ecosystem services provided by irrigated rice agriculture in Thailand: a choice experiment considering attribute nonattendance
通过离散选择实验,研究了泰国公众对灌溉水稻农业提供的生态系统服务的支付意愿,发现公众愿意为干旱缓解、水质改善和乡村景观维护付费,并分析了属性不关注对估值的影响。
This research investigates how the public of a middle-income country, Thailand, values ecosystem services associated with irrigated rice agriculture using a choice experiment. The results show a significant willingness to pay for services such as drought mitigation, water quality and the environment and maintenance of rural lifestyles and rice landscapes. The iterative procedure developed to fully analyze the incidence of attribute nonattendance (ANA) improved the model fit when compared with a multinomial logit model or an ANA model with potentially only one attribute ignored at a time (ANA-1). Moreover, the inferred probability of the class of respondents having attended all attributes was 45%, compared to 9% with ANA-1 model. However, it also suggests that 55% of the respondents made their choices by considering only two of the five attributes. Finally, this research also suggests that failing to consider ANA does not change the public ranking of scenarios contrasted by the services they would provide but would overestimate the WTP for these scenarios.
