The team is involved in large-scale projects in environmental restoration:
Concerning the Old Rhine, all the results of the ongoing geomorphological monitoring underline the need to widen the Old Rhine downstream of gravel augmentations. This confirms some results already obtained during the INTERREG project Redynamisation of the Old Rhine completed in 2012. The LIVE is positioned to co-pilot with the managers (Grand Est Region, DREAL, Rhine-Meuse Water Agency...) an ambitious restoration program, of INTERREG type, aiming at widening the Old Rhine on its left bank and at carrying out sedimentary recharges upstream from these widening sites. Within this framework, the members of the theme will guide the managers in their choices, in particular by modelling, and will carry out interdisciplinary monitoring.
On a larger scale, we are developing a project for a cross-border observatory of the restoration of the Upper Rhine and for feedback on the restorations carried out (ENGEES funding). A database of more than 140 restoration actions has already been developed. The objective is 1. to capitalize on restoration and monitoring experiences so that the restorations carried out and those to come are as effective and sustainable as possible and 2. to create a permanent network of actors (managers, engineering firms, private companies, scientists) in the restoration of the Upper Rhine. The further development of this cross-border observatory is a clear objective of the theme.

The current context of global change, ongoing and future changes in the dynamics of the water cycle (resources, hydrological extremes) but also the arrival of potentially invasive exotic species, shake up our knowledge of continental hydrosystems. The effects of these different factors can be confusing to those of restoration, which requires a holistic approach to hydrosystems while addressing their complexity.
Within the framework of the EMYS-R project, France, Germany, Poland and Latvia are joining forces to evaluate wetland restoration actions on a European scale for the reintroduction of the Cistude turtle and biodiversity. In France, the laboratories involved are the Institut pluridisciplinaire Hubert Curien (IPHC | CNRS Unistra) and the Laboratoire image, ville, environnement (LIVE | CNRS Unistra).

Streams are an important landscape feature in the Upper Rhine region and are of great ecological and economic importance. However, these environments are also significantly affected by human activities. The quality of the watercourses has been physically altered in response to past uses. Developments have altered their structure by modifying their course, banks and riparian zones. These changes have frequently resulted in the destruction of aquatic habitats essential to the life cycle of aquatic organisms, and a decrease in longitudinal continuity that impacts both the migration of fish species and the extent of their home range. These changes modify the natural bouquet of ecosystem services (ESS) provided by the biodiversity of rivers. Biodiversity includes not only species diversity, but also genetic diversity, i.e., the diversity of genes between individuals in a population. A high aquatic diversity (species diversity and genetic diversity) ensures a potential for adaptation to changing environmental conditions (resilience), whether these changes are induced by man or by nature itself. This diversity is also the basis for all other ecosystem services provided by the environment.
Our research questions are the following:
Our compartments of interest are macroinvertebrates, aquatic vegetation and riparian buffers.
