【 摘 要 】

The management of water issues at the watershed scale has become common practice among policy makers throughout the world. To help improve both policy and acceptance of policy, the inclusion of stakeholders in policy and decision-making processes has become the modern paradigm of watershed management. A recent addition to this method is the pairing of stakeholder input and computer modeling. At the same time, conflicts between farmers and non-farmers have been increasing at the rural-urban interface, with water-quality concerns as a central issue. This paper utilizes Preference Modeling to compare how stakeholder preferences, with a specific focus on farmers and non-farmers, would impact water quality in a large-scale watershed. Preference Modeling consists of scenarios developed from the preferences of stakeholder groups as determined by survey results. Using two different survey methods, this study sought the preferences of the general public within one watershed in southeast Michigan towards Best Management Practices that reduce agricultural runoff from fields. Survey results were analyzed based on stakeholder type, and preferences were run through the SWAT computer model of watershed hydrogeochemisty to simulate possible outcomes of stakeholder preferences. According to the SWAT model, the most effective stakeholder preference for improving water quality resulted in a 3% reduction in suspended sediments, a 22% reduction in total phosphorus, and a 27% reduction in total nitrogen. This study found that different stakeholder groups often had common ground and that opinions were often similar but the reasons behind those opinions were different. The preference futures demonstrated several paths to a similar result; most of the stakeholder preference futures in this study resulted in improved water quality over status quo.
