International audience ; River functioning is closely influenced by land uses, along the stream itself and throughout the catchment. Land uses can be seen as both the expression of the natural environment and the result of increasing human activities. Land uses generate various pressures that affect river water quality at different scales of time and space. The assessment of multi-scale impacts of land use on river water quality is a major issue for scientists and for water managers who have to reach ambitious and rigorous legislative objectives. The 'driving forces, pressures, state, impact, responses' (DPSIR) conceptual framework is promoted by the European Environmental Agency for this purpose. A rigorous methodology, following a decision cycle-based approach, has been settled to help the implementation of the DPSIR on an environmental issue and its test on a field site. We develop a system of indicators based on the literature review and in accordance with water managers. The selected indicators are able to characterize the spatial and temporal evolution of water quality, land uses and their interactions. Pressure indicators are built according to the nature of the land use, the distance to rivers and the location in the watershed, at three spatial scales. We use two land-uses databases, the European Corine Land Cover database for macro-scale indicators and a high-resolution map for meso-scale and micro-scale indicators. Water quality status is characterized by a bioindicator based on population of invertebrates. The methodology is tested on the Ognon basin, which is a sub-catchment of Saône River (France). Results show that it is easy to implement the driving forces–pressures–state–impacts–responses for land use and river ecosystems framework on a medium-size catchment. But some limitations must be underlined: (1) the land-use data suffer from a lack of precision in their topological description and in the definition of the land-use nomenclature; (2) there was not enough bioindicators data to analyse, both ...

Lastly, this study leads us to work in close cooperation with water stakeholders, to share a common conceptual framework and to support their decision-making.

International audience ; Les cours d'eau sont des systèmes fragiles et complexes dont le fonctionnement peut être altéré par les activités anthropiques. Guidée par des cadres législatifs stricts et ambitieux, la gestion des cours d'eau implique de nombreux acteurs ayant chacun des objectifs propres en fonction des échelles auxquelles ils opèrent. La littérature identifie clairement l'occupation du sol comme une variable clé de l'estimation des pressions qu'elles soient positives ou négatives. Evaluer les impacts multi échelle de l'occupation du sol sur la qualité des cours d'eau est une question majeure pour les gestionnaires et les scientifiques. L'objectif de notre communication est de présenter l'adaptation du cadre conceptuel DPSIR (" driving forces, pressures, state, impact, responses ") de l'Agence Européenne de l'environnement pour structurer les informations et la construction des indicateurs. Les drivers et les pressions sont estimés à partir des données d'occupation du sol et les données d'états et d'impacts sont estimées par les valeurs d'IBGN et de l'EQR-IBGN, les réponses sont exprimées en termes de potentialités de restauration. Le bassin de la Saône a été choisi comme bassin d'application, en raison de ses caractéristiques hydrogéographiques (superficie de 30 000km² et 9000km de cours d'eau) et de la diversité des activités anthropiques présentes. / Rivers' functioning can be altered by human activities.
