This Report synthesizes the main results obtained throughout the ADVISOR research project ("Integrated Evaluation for Sustainable River Basin Governance") funded by the European Commission, under the - 'Energy, Environment and Sustainable Development' theme of the 5th Framework Research Programme. The aim of ADVISOR was to improve the understanding of evaluation processes as part of river basin planning and management and to provide a framework supported by a toolkit for the conduct of integrated and participatory evaluations. The project comprised four work-packages. Work Package 1 examined past water project or plan evaluation cases in five EU states and drew insights on the problems of past evaluation practices. Work Package 2 interpreted these past experiences from different analytical angles leading to a theory for an integrated evaluation process, emphasising issues of deliberation, multiple values, quality in the use of information and governance. Work Package 3 moved from theory to practice. Different tools which could contribute to integrated evaluation processes were tested in experimental case applications. These included scenario workshops, mediated modelling supported by a quality assurance protocol, social multi-criteria evaluation, cost-effectiveness analyses and monetary valuation. Work Package 4 aimed at transferring the experience and lessons learned during the ADVISOR project to policy makers, contributing especially to the implementation process of the Water Framework Directive. A guidance document for designing and implementing Integrated Deliberative Decision Processes (IDDP) was developed, detailing a step-by-step procedure to achieve integrated evaluations. The synthesis of the main results achieved throughout the ADVISOR project is presented in this report in three parts: Part A sets the stage for the role of integrated evaluations in river basin planning and management; Part B unfolds the set of relevant principles and tools developed in the project and Part C concludes with futures challenges for integrated evaluation processes.
