Le territoire limnique, une alternative à la gouvernance des plans d’eau par masses d’eau ?
Published 2017-12-01“…A geographical, geosystemical, then regional approach based around ‘water territories' has allowed research and mentalities to develop, but the multiplicity of territories generated constitutes a brake against the questioning of the power of hydraulic engineers. And yet, by fully integrating systemic approaches and those of the social sciences, it is possible to consider malleable forms of regionalization according to the criteria and periods and more appropriate to the objectives of "good water status" which have been set at the European level. …”
