“…For another Danish catchment, the Limfjorden catchment, for which load reductions requirements are higher and the estimated costs per kilogramme N almost twice as high, the costs would increase from EUR 40 to 57 million per year. The fact that the mitigation costs are not linear but most often marginally increasing supports our conclusion (Hasler et al, 2014). Although a 47 % overestimation of N loads cannot be assumed for all sites, the example shows that significant costs may arise from basing WFD implementation on incorrect measurement results.…”

“…the current state) and the availability or feasibility of employing different mitigation measures. To illustrate the extent of the costs, for Ringkoebing catchment, the recipient for Odderbaek, the average cost of N reduction is estimated to EUR 5 per kilogramme N (Jacobsen, 2012) and the total costs of achieving the required reduction are estimated to EUR 2.2 million per year (Jacobsen, 2012). If N loads at all monitoring sites in the catchment are assumed to be overestimated by the 47 % observed at Odderbaek, total annual costs for attaining the N target for Ringkoebing fjord would increase to EUR 2.9 million per year.…”

Abstract. Eutrophication of aquatic ecosystems caused by excess concentrations of nitrogen and phosphorus may have harmful consequences for biodiversity and poses a health risk to humans via water supplies. Reduction of nitrogen and phosphorus losses to aquatic ecosystems involves implementation of costly measures, and reliable monitoring methods are therefore essential to select appropriate mitigation strategies and to evaluate their effects. Here, we compare the performances and costs of three methodologies for the monitoring of nutrients in rivers: grab sampling; timeproportional sampling; and passive sampling using flowproportional samplers. Assuming hourly time-proportional sampling to be the best estimate of the "true" nutrient load, our results showed that the risk of obtaining wrong total nutrient load estimates by passive samplers is high despite similar costs as the time-proportional sampling. Our conclusion is that for passive samplers to provide a reliable monitoring alternative, further development is needed. Grab sampling was the cheapest of the three methods and was more precise and accurate than passive sampling. We conclude that although monitoring employing time-proportional sampling is costly, its reliability precludes unnecessarily high implementation expenses.

“…Utilisation of this characteristic of the models are applied in cost-minimising scenario modelling, and the main feature of the models is the ability to map the results regarding the implementation of measures, fertilizer inputs and resultant loads to the fjord. A similar model structure is used in Hasler et al (2014), which models the entire Baltic Sea region. Since wetlands and the retention in soil, ground-and surface water are included, the models can be run to estimate the saved costs (or replacement costs) of these regulating ecosystem services.…”

Assessment of Ecosystem Services and Water Accounting Methodologies for Integrated Water Resources Management in water scarce basins.

However, the existing methodologies are disconnected from the real requirements of water resources planning and management in complex river basins such as the ones suffering from water scarcity. The Water Accounting frameworks adopt a financial accounting perspective that is too exhaustive for the purpose of transmitting the relevant water stocks and flows for water managers and users in a river basin, and that entail less accuracy in the global water balance. Also, the analysed Ecosystem Assessment Tools overlook the influence of water management as well as the temporal and spatial variability of water resources and demands. This Thesis proposes methodologies for Water Accounting and EcosystemServices Assessment which overcome the identified limitations and are especially adapted to be implemented in water scarce river basins. The Australian Water Accounting Standards are simplified to avoid exhaustive accounting for the sake of accuracy and transparency of water management information. An improved version is fully designed, and some criteria are proposed to guide its implementation at river basin scale with the purpose of improving public information and governance. A set of Integrated Water Resources Management Tools embedded in the DecisionSupport System AQUATOOL is tailored with economic information in order to obtain the benefits of three Freshwater Ecosystem Services considering the influence of water management with a detailed time step.The application of the resulting methodologies to different cases of study show the relevance of adopting a water management perspective in order to capture all the complexity of water scarce river basins in the results, so that they are useful for informed decision making. The Water Accounting results disclose synthesised and relevant information for water users and Finally, the methodologies are put into context inside the Integrated Water Resources Management process that covers the target variables to consider, the tools that allow analysing the influence of management actions on them, the indicators that are more informative to water managers, and the ways to transmit the information to the general public.Furthermore, the types of analyses which can be conducted with the proposed methodologies are detailed, and illustrated with examples in scientific literature.The presented research is based on published work, which is expanded or detailed, and includes other non published material. The result is a Thesis that provides improved results and conclusions with respect to the stand-alone papers.v Resumen A pesar de que la planificación y gestión de los recursos hídricos ha evolucionado enormemente, existe todavía discordancia entre la misma y la Gestión Integrada de Recursos Hídricos. A la luz de la Directiva Europea Marco del Agua y otras Políticas Europeas relacionadas con el agua y la sostenibilidad, la Contabilidad del Agua y la evaluación de los Servicios de los Ecosistemas se han identificado como herramientas que pueden ayudar a aproximarse a la Gestión Integrada ...
