Abstract: The ESManage project tested an eight-step methodological framework to help embed ecosystem services and the ecosystem services approach into policy and decision-making for the sustainable management of water resources, as required by the Water Framework Directive (WFD). It involved identification of relevant freshwater ecosystem services, prediction of how they change when management measures are implemented and economic valuation of those changes. The focus of the research was on ecosystem services from rivers, engaging stakeholders in three case study catchments to explore the ecosystem services derived from these very different rivers and undertake economic valuation of the benefits that people obtain from enhancements to ecosystem services in those rivers. Modelling, using both a hydrological and a nutrient load apportionment model, was used to quantify changes in flows and inputs of pollutants (nutrients and sediment) associated with the alternative catchment management scenarios (e.g. intensification, extensification and riparian measures such as tree planting), whereas Bayesian belief network modelling was used to predict the resulting changes in ecological responses and their effects on selected ecosystem services (e.g. clean water, angling, wildlife). The focus was on managing diffuse pollution from agriculture, assuming unchanged inputs from domestic septic tanks and point sources, e.g. wastewater treatment plants, that also contribute to water quality problems in the study catchments. The intensification scenarios considered potentially pro rata changes in nitrogen, phosphorus and sediment inputs assumed to arise from an increase in stocking density, whereas extensification related to the corresponding effects as a result of reductions in stocking density. The “choice experiment” valuation technique was then used to quantify the economic benefits that people obtained from enhancements to river ecosystem services. In addition, data were collected on the cost of wastewater treatment to demonstrate the benefits of natural regulating ecosystem services.
