Simple download service (Atom) of the dataset: Municipalities in the broad sense (communities or cadastral sections of municipalities) in ‘vulnerable zone’ in the Grand-East in the territory of the Rhine-Meuse Water Agency

Vulnerable areas are land designated in accordance with European Directive No. 91-676. A vulnerable area is a part of the territory where water pollution by direct or indirect discharge of nitrates of agricultural origin or other nitrogen compounds that may become nitrates threatens in the short term the quality of aquatic environments and, in particular, the supply of drinking water. Vulnerable areas shall be considered as vulnerable areas where: — Groundwater and surface fresh water, in particular those used or intended for water abstraction for human consumption, with a nitrate content exceeding 50 milligrams per litre, — The waters of estuaries, coastal and marine waters and surface fresh waters which undergo eutrophication to which the enrichment of the water with nitrogen compounds from agricultural sources contributes. An action programme shall be implemented in each department concerned, setting out the requirements to be complied with by all farmers in the corresponding vulnerable area. They are constructed in consultation with all relevant stakeholders, based on a local diagnosis. They aim to correct the most pollution-generating practices. Outside vulnerable areas, a national code of good agricultural practice is voluntary. Each vulnerable area corresponds to a prefectural decree (coordinating basin prefect) after consulting the departmental council of Hygiene, the general and regional councils and the basin committee. Vulnerable areas shall be reviewed at least every 4 years. This decree is the founding regulatory text of the vulnerable area. The perimeter of vulnerable areas is defined by basin administrative division according to 2 methods: 1) Municipal boundaries: It covers the boundary of the set of designated municipalities in vulnerable areas. (2) Cadastral limits (infra-communal): It covers the cadastral sections selected for municipalities designated in vulnerable areas. In the case of this dataset, it is the “cadastral” (infra-communal) perimeter. In the event that a subsequent order completes the previous order, only the date of the last order will be retained. The list of vulnerable areas is established under the responsibility of the basin DREALs. Multipolygons and hole polygons are allowed.敏感区域（vulnerable areas）指依据欧盟第91-676号指令划定的土地。 敏感区域是指辖区内因直接或间接排放农业源硝酸盐或其他可转化为硝酸盐的氮化合物而引发的水污染，在短期内威胁水生环境质量，尤其是饮用水供应的区域。 符合以下情形的区域应被认定为敏感区域： — 地下水和地表淡水（尤其是用于或拟用于人类饮用水取水的水体）中硝酸盐含量超过50毫克/升； — 河口、近岸海域、海洋水域以及地表淡水出现富营养化，且该富营养化由农业源氮化合物对水体的氮负荷贡献所致。 各相关省应推行行动计划，明确对应敏感区域内所有农户需遵守的生产要求。此类计划基于本地环境诊断，经与所有相关利益相关方磋商后制定，旨在纠正污染程度最高的农业生产行为。 不在敏感区域范围内的地区，国家良好农业规范（good agricultural practice）为自愿性执行标准。 每一处敏感区域均需在征询省卫生委员会、省及大区议会与流域委员会的意见后，通过省长令（协调流域省长令）予以划定。敏感区域至少每4年需进行一次全面复核，该省长令为敏感区域划定的法定依据文本。 敏感区域的边界依据流域行政区划，通过以下两种方式划定： (1) 市镇边界：覆盖被划定为敏感区域的全部市镇的行政管辖边界； (2) 地籍界址（infra-communal，公社以下级别）：覆盖被划定为敏感区域的市镇中选定的地籍地块。 本数据集采用的是"地籍界址（公社以下级别）"边界。 若后续政令对前期划定政令进行补充完善，则仅保留最新政令的生效日期。 敏感区域名录由流域级地区环境管理机构（DREALs）负责编制。 本数据集支持多面要素（multipolygons）与带洞面要素（hole polygons）。
