Limitation du transfert hydrique des produits phytosanitaires par les zones tampons : caractérisation de l'existant et proposition de dispositifs correctifs et complémentaires

Abstract : WFD application supposes that the ecological « good status » for water bodies be reached before 2015. However in France, this good status may not be reached for a large number of waterbodies, in particular because of the contamination of the water resource by non-point source pollutions, mainly by nitrogen and pesticides. In this context, buffer zones may be useful mitigation solutions to limit pollutants transfer towards surface water bodies. In order to optimize their efficiency considering pesticides transfer, Irstea prepared two guides, which take place in watershed scale diagnosis logic, in order to integrate buffer zones in handling a catchment so as to limit the water surface transfers. They are used in a second step, the first one being the diagnosis establishing the risk of water contamination by pesticides at the scale of small catchment.
