Diagnosing and restoring aquatic biodiversity
In a context of global change, what is the actual status of biodiversity in France? How will current and future changes in the climate affect fish populations, plants and plankton communities? What will be the effects of biological invasions on aquatic biodiversity? What will be the consequences of changes in discharge regimes and in river hydromorphology? How can the managers of aquatic environments assess these impacts? And how can they work to limit the effects and to restore biodiversity, both now and in the future?
The symposium in Paris titled "The outlook for managing aquatic biodiversity in rivers and lakes" brought together over 200 participants, including research units, State services, local governments, companies, environmental-protection groups and NGOs, to address these questions. The 2 days of discussions between scientists and water managers provided feedback on approximately 30 partnership research projects on aquatic biodiversity. The symposium was organised by Onema (National agency for water and aquatic environments), with assistance from IOWater (International office for water). The symposium was held in Paris, on 14-15 November 2012.
