[DREAL OCCITANIA] Groundwater distribution area on the Adour-Garonne basin

Description: Water distribution areas are areas comprising basins, sub-basins, fractions of sub-basins or aquifer systems, characterised by a lack of resources, other than exceptional, in relation to needs.

* Procedure: These areas are defined by Decree No 94-354 of 29 April 1994, as amended by Decree No 2003-869 of 11 September 2003. Classified by decree, these areas are translated into a list of municipalities by the prefects of the departments. In these areas, the thresholds for authorisation and reporting of samples from surface water and groundwater are lowered. These provisions are intended to enable better control of the demand for water, in order to ensure the best preservation of aquatic ecosystems and the reconciliation of economic uses of water. In these areas, water withdrawals of more than 8 m³/h are subject to authorisation and all others are subject to reporting.

数据集说明：水资源匮乏区是指由流域、子流域、子流域局部区域或含水层系统组成的区域，其核心特征为水资源供给量相对于用水需求存在非极端性的资源短缺。

* 划定程序：上述区域由1994年4月29日第94-354号法令划定，该划定标准经2003年9月11日第2003-869号法令修订。经法令划定后，各省省长需将此类区域转化为所辖市镇清单。在此类区域内，地表水与地下水采样的许可阈值及报备阈值均有所下调。上述规制条款旨在强化水资源取用需求的管控，以实现水生生态系统的有效保护，并协调水资源的各类经济利用行为。在此类区域内，取水量超过8立方米/小时的取水活动需取得行政许可，其余取水活动则需履行报备手续。
