The aim is to highlight the seminars by presenting the main lines of these seminars in the form of a short summary illustrated with examples and testimonials. They help to disseminate information on the major issues of tomorrow, on the preservation and restoration of biodiversity, and in particular for achieving the goal of achieving good water status imposed by European and national policies.

Natural water retention measures (NWRM) comprise an array of initiatives to restore the natural properties of ecosystems in view of slowing the runoff of surface waters and increasing the infiltration capacity of soil. Examples from projects in France stress the multiple benefits of these measures.
What happens when a river is once again free to run? In the Sélune valley (Manche department in Normandy), the largest dam-removal project in Europe is being carried out in step with an unprecedented scientific programme aiming to better understand the changes in the ecosystem, monitor the return of migratory fish and participate in the future development of the valley.
The French National River Restoration Centre, led by the French Agency for Biodiversity (AFB), organised a workshop and field visits on river continuity restoration initiatives. This was an opportunity for practitioners involved in the management of aquatic environments to discover reproducible actions targeting multiple issues, carried out in Italy, the United Kingdom, Finland and France.
The participants brought together for the “Head water streams – How to reconcile the issues affecting these exceptional territories?” symposium took part in interesting debates on the issues, knowledge and actions undertaken in these territories. This symposium forms part of the actions of the 2014-2018 National Plan of action for Wetlands.
The meeting, with an array of speakers, enabled researchers, elected officials, local governments, State services, developers, managers of natural areas and associations to trade thoughts on the issues, techniques and measures involved in promoting biodiversity and ecological continuity. The operational phase in network implementation has raised a number of questions.
Natural water retention measures as well as aquatic ecosystems’ restoration and preservation provide means to achieve good water status as required by the Water Framework Directive (WFD). In order to make progress on that topic, the workshop aimed to promote a better integration of European directives and policies through river restoration and natural water retention measures.
How can operational needs be identified in order to steer RDI (research, development, innovation) policy toward the scientific and technical developments most useful for water managers? What forms of coproduction must be implemented to ensure that the intended persons can effectively use the results? And what transfer policy should be instituted so that the results are fully exploited?
The purpose of the event, a forerunner to the 7th World water forum and the Paris-Climat 2015 meeting (COP21), was to facilitate discussions between scientists and elected officials on the topic of water and climate change in view of jointly laying the groundwork for future improvements in the science-policy interface. These discussions are essential in order to transform scientific knowledge into actual water planning and management policy.
Several of the leading international experts on environmental specimen banks (ESB) met for 2 days of discussions that highlighted the value of these tools in meeting the challenges raised by pollution management and biodiversity conservation. The idea of creating an ESB for continental aquatic environments in France was floated.
Over the past 5 years, the development of bioassessment tools suited to the overseas territories has made rapid progress. This symposium was an occasion to report on the progress achieved and to assess the work that must still be undertaken for the upcoming management cycles of the Water framework directive (WFD).
