The members of the Chair, Karl Matthias Wantzen, Tours University (chair holder), Aziz Ballouche, Angers University (co-chair) and Isabelle Longuet, Mission Val de Loire (co-chair), together with the network of partners to the Chair all over the world, are working on a harmonization between human activities in river landscapes (riverscapes) and the diversities of their biological and cultural heritages. The main activities of the Unesco Chair are the scientific exchange between the partners in North and South, the identification of research issues, performance of comparative studies and the publication and teaching on best practices on science-based river management.
