Integrated Deliberative Decision Processes for Water Resources Planning and Evaluation is part of the ADVISOR ("Integrated Evaluation for Sustainable River Basin Governance") research project funded by the EC, under the "Energy, Environment and Sustainable Development" theme of the 5th Framework Research Programme. The aim of ADVISOR is 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. Integrated Deliberative Decision Processes for Water Resources Planning and Evaluation is Work Package 4 of the project and helps to transfer the experience and lessons learned during the ADVISOR project to policy makers, contributing especially to the implementation process of the Water Framework Directive. An Integrated Deliberative Decision Process (IDDP) is proposed to be adopted as the platform to achieve integrated evaluations and this book explains and provides a step-by-step guidance on how to design and run such a process. Integrated Deliberative Decision Processes for Water Resources Planning and Evaluation has been written especially for policy makers, with theoretical reflections also provided where these bear importance to practical implementation.
