An Internet-based Spatial Decision Support System for Rangeland Watershed Management
نویسندگان
چکیده
The impact of livestock grazing on water quality, especially erosion and sedimentation, is an important concern in the southwestern United States. In response to Federal and State regulations, Best Management Practices (BMPs) for rangeland management are being developed and implemented in many western states, although the efficacy and economic impact of many practices have not been examined. To assess the potential effectiveness of BMPs, a Spatial Decision Support System (SDSS) has been designed to integrate water quality, livestock management and economic concerns. The SDSS was developed through the integration of hydrologic, erosion, livestock management and economic simulation models linked with a geographic information system and database management system. The SDSS can help managers select the type and location of BMPs based on sitespecific data and is deployed via the Internet providing access through a web browser. The SDSS provides land managers with a means to identify critical areas causing water quality degradation and design and implement watershed management practices to improve water quality. The poster will describe the SDSS and provide case study examples of its application.

متن کاملMultiple - Objective Decision Making for Agroecosystem Management
Multiple-objective decision making (MODEM) provides an effective framework for integrated resource assessment of agroecosystems. Two elements of integrated assessment are discussed and illustrated: (1) adding noneconomic objectives as constraints in an optimization problem; and (2) evaluating tradeoffs among competing objectives using the efficiency frontier for objectives. These elements are i...
