Vulnerable areas are the lands designated in accordance with Article 3(2) of European Directive 91-676, the objectives of which are to reduce the pollution of water caused or induced by nitrates from agricultural sources, and to prevent any further pollution of this type.
A vulnerable zone is a part of the territory where pollution of water by the direct or indirect discharge of nitrates of agricultural origin or other nitrogen compounds likely to turn into nitrates threatens in the short term the quality of aquatic environments and in particular the supply of drinking water. Areas where: surface and groundwater fresh waters, in particular those intended for drinking water, have or are at risk of having a nitrate content greater than 50 mg/l, estuary waters, coastal or marine waters and surface fresh waters which have undergone or show a tendency towards eutrophication likely to be #x27; be effectively combated by reducing nitrogen inputs.
An action programme is implemented in each department concerned, setting out the requirements to be met by all farmers in the corresponding vulnerable zone. They are built in consultation with all the actors involved, on the basis of a local diagnosis. They aim to correct the most polluting practices. Outside vulnerable areas, a code of good agricultural practice, established at national level, is voluntary.
Each vulnerable zone corresponds to a prefectural decree (prefect coordinator of the basin) after consulting the departmental council of Hygiene, the general and regional council and the basin committee. Vulnerable areas are reviewed every 4 years. Each zone is spread over a geographical area consisting of a set of municipalities. In the event that a subsequent order supplements the previous order, only the date of the last order will be retained.
The list of vulnerable areas is drawn up under the responsibility of the basin DREALs.
