摘要：The Water Framework Directive (WFD) sets targets of "Good Ecological Status" for water bodies across the EU. Environmental regulatory authorities must undertake economic analysis of all water bodies as part of the process of drawing up catchment management plans. In this paper, we test the transferability of benefit estimates across the kinds of smaller catchments where original benefits estimation is unlikely to be undertaken on grounds of costs. This is done in a context where agricultural-source nonpoint pollution and irrigation water abstraction are the main threats to ecological status.
