Structured Decision Making to Meet a National Water Quality Mandate.

摘要: Water quality criteria are necessary to ensure protection of ecological and human health conditions, but compliance can require complex decisions. We use structured decision making consider multiple stakeholder objectives in a water management process, with case study the Three Bays watershed on Cape Cod, Massachusetts. set goal meet or exceed nitrogen load reduction target for four key objectives: minimizing economic costs implementing actions, complexity permitting maximizing acceptability provision ecosystem services (recreational opportunity, erosion flood control, socio-cultural amenity). used multi-objective optimization sensitivity analysis generate many possible solutions that implement different combinations nitrogen-removing actions reflect tradeoffs between objectives. Results show technological advances controlling household sources could provide lower cost positive impacts services. Although this approach is demonstrated Cod data, decision-making process not specific any be easily applied elsewhere.
