LTSER Zone Atelier Loire - France
LTSER Zone Atelier Loire
Natural risk zones
The LTSER Zone Atelier Loire belongs to LTER-France network. The ZAL studies the Loire River basin (127 000 km2) on a long term scale (-15000 years until today). It focuses on the functionning of the hydrosystem, the human societies living there and on the co-evolution hydrosystem – society. The LTSER hosts several study sites subjected to measurement or data collection campaigns during work involving different disciplines as well as managers around a key question. The Maine watershed site is a large area to study dynamics of a low-energy river draining a 22,000 km² basin. The Louroux (Indre-et-Loire) site includes operation of an agricultural catchment area (24 km²). The bog of la Guette (Cher, Sologne, 25 ha) is an instrumented site to follow the rehabilitation of eco-hydrological services (storage of carbon, hydrology, biodiversity). Mareau-aux-prés islands (Loiret, St-Mesmin, 13 ha) is a site subjected to river dynamics which allows to understand the impacts of works carried out in the dyked bed and dynamics of the landscapes.
General Characteristics, Purpose, History
The studies of the LTSER mainly concern the society-environment interactions in direct or indirect connection with the river or its main tributaries. The network also aims to meet the social, economic and political expectations and to provide elements to develop a relevant prospective approach. The LTSER Zone Atelier Loire develops transdisciplinary research involving natural and social scientist (ecologists, pedologists, hydrologists, geographers, sociologists, archeologist) and regional stakeholders. The research aims at better understanding and documenting the functioning and dynamics of the Loire through the abiotic, biotic and socio-systemic components of the Loire watershed, as well as their interactions over the long term, thus favoring an approach based on observation. Particularly, we developed research questions on sediment and organic matter transfers, restoration of ecological continuity, wetland functioning or vegetation dynamics.
