Estimating the benefits of water quality improvements under the Water Framework Directive: are benefits transferable?
通过选择实验法，测试英国两个小流域水质改善效益估计的可转移性，并探讨转移测试的最适技术，包括环境属性偏好相关性和转移值与原始值的可接受差异。
The Water Framework Directive sets an objective of ‘Good Ecological Status’ for water bodies across the EU. Non-point pollution from agriculture is a major reason for the failure of rivers in the UK to meet this target. In this paper, we use choice experiment methodology to test the transferability of benefit estimates of water quality improvements for two small catchments where agricultural-source non-point pollution and irrigation water abstraction are the main threats to ecological status. We also investigate the most appropriate techniques to apply to transfer testing, including allowing for correlation between preferences for environmental attributes, and testing for acceptable differences between transferred and original values.
