La stabilité limnique dans le bassin de la Vienne : La place des plans d’eau au sein des milieux et des sociétés depuis le XIXe siècle

Abstract : The knowledge of French waterbodies is affected by three scientific bias making some current management systems ineffective: (i) the ignorance of their number and exact locations by the State or decentralized administrative bodies, (ii) the interpretation as fluvial hydrosystems and not as limnosystems; and (iii) the omnipotence of the biological approach among officials and representatives of power to the detriment of the social approach, although ponds and other little artificial waterbodies are objects created by and for humans. Here, the authors present a diachronic approach (1830 and 2005) allowing the understanding without a priori of the place of waterbodies in landscape to consider lentic territories according to their level of limnic stability. Through the case study of Vienne’s basin, the authors reveal the multitude of differentiated answers according to sociological and economical changes, and study the presence or absence of waterbodies according to agronomical features. The basin downstream remains rather stable, whereas the crystalline part upstream and its contact with the sedimentary basin have been largely modified.
