Index-Based Cost-Effectiveness Analysis vs. Least-Cost River Basin Optimization Model: Comparison in the Selection of a Programme of Measures at the River Basin Scale
Increasing water scarcity challenges conventional approaches to managing water resources. More holistic tools and methods are required to support the integrated planning and management of fresh water resources at the river basin level. This paper compares an index-based cost-effectiveness analysis (IBCEA) with a least-cost river basin optimization model (LCRBOM). Both methods are applied to a real case study to design a cost-effective portfolio of water demand and supply management measures that ensures compliance with water supply and environmental targets. The IBCEA is a common approach to select programmes of measures in the implementation of the EU Water Framework Directive. We describe its limitations in finding a least-cost solution at the river basin level and highlight the benefits from implementing a LCRBOM. Both methods are compared in a real case study, the Orb river basin, in the south of France. The performances of the programmes of measures selected by the two methods are compared for the same annual equivalent cost. By ignoring the spatial and temporal variability of water availability and water demands in the river basin and the interconnection among its elements, the aggregated approach used in the standard IBCEA can miss more cost-effective solutions at the river basin scale.This paper is based on work conducted as part of several projects over more than 6 years.

Assessing Management Regimes in Transboundary River Basins: Do They Support Adaptive Management?
River basin management is faced with complex problems that are characterized by uncertainty and change. In transboundary river basins, historical, legal, and cultural differences add to the complexity. The literature on adaptive management gives several suggestions for handling this complexity. It recognizes the importance of management regimes as enabling or limiting adaptive management, but there is no comprehensive overview of regime features that support adaptive management. This paper presents such an overview, focused on transboundary river basin management. It inventories the features that have been claimed to be central to effective transboundary river basin management and refines them using adaptive management literature. It then collates these features into a framework describing actor networks, policy processes, information management, and legal and financial aspects. Subsequently, this framework is applied to the Orange and Rhine basins. The paper concludes that the framework provides a consistent and comprehensive perspective on transboundary river basin management regimes, and can be used for assessing their capacity to support adaptive management.Civil Engineering and Geoscience

Rapport de recherche n°1 Projet I-FIVE: instruments et institutions innovants pour appliquer la DCE. Rapport de démarrage
This inception report of the i-Five project presents the research that is planned in the project. Central in project is the evaluation of innovative instruments and institutions (i-3's) for implementing the Water framework directive (2000/60/EC; WFD). Moreover, the transplantability and adaptability of the i-3's for other contexts will be analyzed. In France, the implementation of the WFD in the Thau basin will be studied. Interesting aspects of this implementation process include collaboration between the water sector and land-use planning sector and the cooperation between the authorities and different research projects. In Germany, three area cooperations in the Weser basin will be evaluated, which are novel ways for organizing public participation. In addition, the issue of financing and coordination between governance scales will be analysed. In the Netherlands, the implementation of the WFD Explorer in the Dutch part of the Meuse basin and in particular the area of the waterboard Brabantse Delta will be evaluated. The WFD Explorer is a decision support system for the implementing the WFD. The project will result in a Quick scan method. This method will show the potentials as well as the potential obstacles of the different i-3's, and will help decision-makers to adopt or adapt the i-3 to their own context or to develop their own home-grown i-3
Institutions et instruments innovants pour la mise en ouvre de la Directive Cadre Européenne sur l'eau : Leçons pour le second cycle d'application de la DCE. Comparaison des trois cas étudiés et méthode de pré-tri (QuickScan)
The Water Framework Directive (2000/60/EC; WFD) is one of the most important environmental directives of the EU. It holds the promise of cleaner European waters and better aquatic ecology. Yet, the novelty of the specific requirements of the WFD, combined with the very tight deadlines, has turned the first implementation cycle into an ―experimenting and learning‖ experience. We assumed that effective institutional settings would shape the circumstances in which measures would actually be implemented.The key to the implementation of the WFD proved to be not so much the existence of basin-level organisations, but an awareness of the necessity of a river basin approach as well as a correspondence between institutions in charge of planning measures and those in charge of implementing them. Within the i-Five project, three innovative approaches have been identified and evaluated that may support the implementation of the WFD: The Area Cooperations in Lower Saxony, in which authorities and stakeholder groups from different sectors work together, linking local and state level. The ―animateurs‖ of river - basins in France are a group of individuals who mediate between the water agencies and territorial governments, thus crossing sectorial boundaries and promoting ―ownership of the WFD‖ especially at local level. The WFD Explorer in the Netherlands is an innovative Decision Support System that incorporates technical and ecological expertise and can help setting environmental objectives and selecting measures. Moreover, a ―Quick Scan Method‖ was developed to help water managers in other areas decide whether to adopt/adapt one of these approaches, or possibly develop their own approach using elements from all three approaches. Concerning the implementation of the WFD in general, the following conclusions were drawn: 1. The institutions that decide on objectives and measures should include the ones that fund and/or implement the measures in order to provide optimal conditions for the realisation of the programme of measures. 2. A trans-sectoral river basin approach needs support from European and national policy. 3. Active involvement of stakeholders is severely hindered by focussing on methodological complexities and administrative demands of the WFD rather than the basic principle of improving the water quality in river basins. 4. Balancing top-down and bottom-up processes is necessary to ensure a basic level of standardisation and comparability of approaches, while at the same time acknowledging local conditions and local knowledge. 5. Non attainment of environmental objectives, in itself, does not necessarily imply bad implementation of WFD. 6. Adaptive water management is the way forward in dealing with the unpredictability of ecology and other knowledge/capacity gaps, such as economic issues.La directive cadre européenne sur l'eau (2000/60/EC; DCE) est l'une des directives environnementales les plus importantes de l'UE. Elle semble promettre des eaux plus propres et une meilleure situation écologique aquatique. Cependant, la nouveauté des exigences de la DCE et les délais serrés ont fait du premier cycle de mise en ½uvre un exercice d'apprentissage « chemin faisant ». Nous avions fait l'hypothèse que les dispositifs institutionnels mis en place façonneraient l'application de la DCE et ses mesures. Or nous nous sommes rendu compte que la mise en ½uvre de la DCE ne dépendait pas tant de l'existence d'organisations de bassin, mais plutôt de la conviction partagée de l'importance de l'approche par bassin et de la correspondance entre institutions associées à la planification des mesures et institutions chargées de les mettre en ½uvre. Au sein du projet i-Five, trois approches innovantes pouvant aider la mise en ½uvre de la DCE ont été identifiées et évaluées : Les Coopérations de zones en Basse-Saxe, dans lesquelles les autorités et les parties prenantes de différents secteurs travaillent ensemble en faisant le lien entre le local et le niveau du Land. Les animateurs de bassin versant en France qui sont des médiateurs entre monde de l'eau et collectivités locales, assurant le lien entre secteurs et permettant l'appropriation de la DCE au niveau local. L'explorateur DCE aux Pays-Bas est un logiciel d'aide à la décision qui incorpore de l'expertise technique et écologique et qui peut aider à déterminer des objectifs de qualité et à sélectionner les mesures de restauration. De plus, une méthode de pré-tri (Quick Scan) a été développée pour aider les gestionnaires de l'eau de régions différentes à repérer dans ces innovations ce qui peut les intéresser. Sur la mise en ½uvre générale de la DCE nous avons tiré les enseignements suivants : 1. La séparation entre institutions qui décident des objectifs et des mesures et celles qui financent ou mettent en ½uvre ces mesures conduit à une forte incertitude sur la réalisation du programme de mesure 2. Au niveau du bassin, l'intégration entre secteurs dépend aussi de l'intégration des politiques aux échelons national et européen 3. Les complexités méthodologiques et la charge administrative exigée par la DCE découragent les parties prenantes motivées par le principe general d'amélioration de la qualité des bassins versants 4. Pour assurer la comparabilité des approches et des résultats, un compromise entre centralisation et décentralisation est nécessaire, qui doit permettre de tenir compte des conditions locales et des savoirs locaux 5. La non-atteinte des objectifs environnementaux ne signifiera pas forcément une mauvaise application de la DCE. 6. Une gestion adaptative de l'eau doit permettre de gérer les incertitudes écologiques et les manques de connaissance ou de compétences, notamment en économie
