“…This study (Salvano et al, 2004(Salvano et al, , 2006 illustrates the importance of valuing environmental benefits associated with an improvement of water quality when assessing and implementing new agricultural nutrient management plans. In the province of Québec, the Québec Regulation Respecting Agricultural Operations (RRAO) was implemented in 2002 (and modified in 2005) to ensure the protection of water and soil, as well as aquatic life and human health from agricultural pollution.…”

“…Regarding pollutant concentrations data, the frequency of exceeding a water quality standard can be calculated or visualised using graphs, which is useful when simulations concern the effect of management practices on specific water uses such as swimming or drinking water. Finally, an environmental benefit-cost analysis can be performed for agricultural scenarios based on the cost of implementation of agricultural beneficial management practices and the environmental benefits from recovering potential water uses due to water quality improvement (see Salvano et al, 2004). Note that simulation results obtained from the management scenario are always interpreted and analysed in relative terms with respect to those obtained with the reference scenario.…”

“…As most of human services provided by water are not priced in markets, their economic values first have to be estimated using non-market methods. In this case, a benefit transfer procedure was used (see Salvano et al, 2004Salvano et al, , 2006 for details). As a first approximation, only the monetary benefits associated with water-based recreational activities were evaluated.…”

Abstract. Hydrological and pollutant fate models have long been developed for research purposes. Today, they find an application in integrated watershed management, as decision support systems (DSS). GIBSI is such a DSS designed to assist stakeholders in watershed management. It includes a watershed database coupled to a GIS and accessible through a user-friendly interface, as well as modelling tools that simulate, on a daily time step, hydrological processes such as evapotranspiration, runoff, soil erosion, agricultural pollutant transport and surface water quality. Therefore, GIBSI can be used to assess a priori the effect of management scenarios (reservoirs, land use, waste water effluents, diffuse sources of pollution that is agricultural pollution) on surface hydrology and water quality. For illustration purposes, this paper presents several management-oriented applications using GIBSI on the 6680 km 2 Chaudière River watershed, located near Quebec City (Canada). They include impact assessments of: (i) municipal clean water program; (ii) agricultural nutrient management scenarios; (iii) past and future land use changes, as well as (iv) determination of achievable performance standards of pesticides management practices. Current and future developments of GIBSI are also presented as these will extend current uses of this tool and make it useable and applicable by stakeholders on other watersheds. Finally, the conclusion emphasizes some of the challenges that remain for a better use of DSS in integrated watershed management.

“…The objective of this paper is to illustrate, using the environmental benefit/on-farm BMP cost analysis framework developed by Salvano et al (2004), the value of environmental benefits associated with water quality improvements when assessing nutrient management plans as required by the Quebec Regulation Respecting Agricultural Operations (RRAO). This legislation was first implemented in 2002 to support the reduction of agricultural pollution (MENVQ, 2003) and recently modified with specific amendments regarding manure storage facilities (Gazette Officielle du Québec, 2005).…”

This paper illustrates the importance of valuing environmental goods and services associated with water quality improvements when assessing implementation of on-farm nutrient management plans as required by the Quebec Regulation Respecting Agricultural Operations (RRAO). Based on a case study in the Chaudiere River watershed, two scenarios were considered using the integrated, economichydrological, modelling framework provided by GIBSI: (i) a base-case scenario assuming application of all available manure; and (ii) an on-farm nutrient management scenario based on meeting phosphorus crop requirements with manure and treating any manure surpluses. Two types of management units were selected to evaluate these scenarios: (i) contiguous municipalities (administrative units of agricultural development); and (ii) subwatersheds. Results showed that management at subwatershed levels had larger benefit/cost (B/C) ratios when compared to contiguous municipalities. This illustrates that the watershed is a more meaningful management unit than the municipality, which is not a hydrological unit. For one of those subwatersheds, the B/C ratio was close to one although only various recreational benefits were accounted for in the evaluation. In all likelihood, if a more holistic set of benefits were accounted for, a B/C ratio greater than or equal to one would have resulted. A sensitivity analysis revealed that variations of 37.5%, -22.5%, and -20% for monetary benefits, on-farm manure treatment costs, and average probabilities of exceeding the targeted water quality standard (prevention of eutrophication of rivers), respectively, were necessary to obtain a B/C ratio greater than one.
