A geospatial boundary dataset defining the perimeter of the SAGE du Bassin Houiller water management scheme. The Water Planning and Management Scheme (SAGE) is a French planning tool established by the 1992 Water Act for the balanced and sustainable management of water resources. The dataset is provided by the Bureau de Recherches Géologiques et Minières and was last updated in April 2019.
Use Cases
- Delineate administrative boundaries for water governance based on the defined SAGE perimeter.
- Analyze municipal inclusion for integrated surface and groundwater management based on the scheme's scope.
- Support environmental impact assessments by mapping the territory under specific water management regulations.
- Cross-reference land use or demographic data with the water management zone for sustainability studies.
Strengths
- Perimeter is legally defined by Decree No 2008-DDAF/3-77 of 4 April 2008, providing an official basis.
- Dataset originates from the authoritative Bureau de Recherches Géologiques et Minières (BRGM).
- Explicitly distinguishes municipalities included for overall water management from those for groundwater management only.
