A lot of initiatives for improving the water quality were developed for 15 years in Brittany in response to the European policy and the ecologist requests. This implies the partnerships of farmer organisations, organisms in charge of rural affairs and research and formation institutes.The paper presents the 2 major aspects of a possible original and efficient water policy, in the framework of the water management at the catchment scale : 1) developing new methods of water management, including farming activities, to improve the water quality ; 2) developing new methods of pressure and impact assessment taking into account the complexity of a system submitted to a recent and light water policy, a strong hydrological variability and a long response time.In spite of the co-existence of all the constituents of a coherent policy, this policy seems difficult to build up. Current water quality shows the interest and limits of incentive policy.
