The EuropeanWater Framework Directive(WFD) prescribes economic principles to achieve its ecological targets. The aim is to establish cost-effective measures to attain good ecological status and assess whether the costs of these measures are justifiable in view of the benefits they provide. The complex nature of water problems requires flexible decision-making embracing a diversity of ‘knowledges’. Here, natural and social scientist worked together in an integrated approach ‘ground-tested’ through local stakeholders' knowledge and views. The aims were to: (1) develop a set of steps for implementing this transdisciplinary approach, and (2) critically reflect on the challenges of integrating different strands of knowledge to the specific context of the economics of the WFD. Thiswas tested at a sub-catchment in Scotland. Hydro-chemicalmodelswere used to simulate effectiveness of phosphorous pollution mitigation measures, which was then incorporated into a cost-optimization model. Costs were compared with benefits resulting from water quality improvements. This analysis was accompanied by an iterative local stakeholder consultation process. The research further analysed whether selected measures are ‘future-proof’ in view of climate and land-use changes. Results are used to help set the research agenda for more practical specification of economically sound and socially acceptable ways to deliver theWFD.

This paper presents an application of integrated methodological approach for identifying cost-effective combinations of agri-environmental measures to achieve water quality targets. The methodological approach involves linking hydro-chemical modelling with economic costs of mitigation measures. The utility of the approach was explored for the River Dee catchment in North East Scotland, examining the cost-effectiveness of mitigation measures for nitrogen (N) and phosphorus (P) pollutants. In-stream nitrate concentration was modelled using the STREAM-N and phosphorus using INCA-P model. Both models were first run for baseline conditions and then their effectiveness for changes in land management was simulated. Costs were based on farm income foregone, capital and operational expenditures. The costs and effects data were integrated using ‘Risk Solver Platform’ optimization in excel to produce the most cost-effective combination of measures by which target nutrient reductions could be attained at a minimum economic cost. The analysis identified different combination of measures as most costeffective for the two pollutants. An important aspect of this paper is integration of model-based effectiveness estimates with economic cost of measures for cost-effectiveness analysis of land and water management options. The methodological approach developed is not limited to the two pollutants and the selected agri-environmental measures considered in the paper; the approach can be adapted to the cost-effectiveness analysis of any catchment-scale environmental management options.
