Knowledge for action
The Knowledge for action series provides professionals in biodiversity sector (instructors, students, scientists, engineers, managers, etc.) with information on recent research and science-advice work.

Invasive alien species (IAS) and their impacts represent a growing concern for the managers of natural areas.That is particularly true for aquatic environments where an array of stakeholders are now taking action. In parallel, public policies are coming into play on the national level and the European Union now has a regulation in this field. These volumes offer highly useful information while attempting to address the specific aspects of each situation, including the site, the species to be managed and the necessary technical and financial resources.
Restoration is an important issue in managing water and aquatic environments, however the concept itself is still debated. To improve our understanding of this paradigm, investigate its contributions and limits, and look at the potential changes in its application in the field of water and aquatic environments, we reviewed current definitions of restoration as it is now practised in France and abroad.
This book is intended for public and private stakeholders involved in applying or affected by environmental regulations in general and water regulations in particular. It describes the current scientific, legal and operational situation as well as the progress already made and that required to fully take into account ecological damages, on the basis of in-depth scientific and technical knowledge combined with current developments in the human and social sciences.
Diffuse pollution is currently one of the major pressures on Europe’s water resources. To achieve the objectives of the water framework directive, the European Union member States must address this type of pollution. It is difficult to measure and control, notably due to the multitude of sources involved. An exchange of practices and experience on this issue, between numerous stakeholders from the various basin organisations of European and neighbouring non-European countries was organised in 2015.
Economic analysis plays an increasingly important role in managing water resources and aquatic environments. Using concrete examples, this document shows how hydro-economic models can assist in dealing with three major problems confronting the managers of water resources.
This second volume illustrates the situation discussed in the first volume with feedback from management projects in continental France and Europe.
Invasive alien species (IAS) are acknowledged as one of the main causes of biodiversity loss worldwide. The objective of these 2 volumes is to contribute to the debates on how to manage IASs, to provide a general outline on current knowledge (volume 1) and a number of specific examples (volume 2) to assist managers of aquatic environments and policy makers in their respective tasks to better manage these species. The first volume presents the current situation concerning invasive alien species in aquatic environments in continental France.
Environmental managers work to promote, conserve and restore environments. However, any efforts toward rational management must be based on previously acquired knowledge on not only a given environment (e.g.what is an aquatic ecosystem and how does it function?), but also on the people and societies living nearby. This is because all environmental work takes place in a given cultural and social context. Management is therefore a question of knowledge and, above all, of the diversity of knowledge. But what is meant by knowledge on the environment?
Aquatic environments constitute ecological treasure houses, represent a unique cultural heritage and provide society with important economic resources. What will be the consequences of climate change on the hydrology of aquatic environments? How will aquatic ecosystems and organisms react? What can be done to limit their vulnerability? Fish are emblematic life forms in rivers and an important resource for humans. They are one of the lifeforms that will potentially be impacted by climate change.
Obstacles to flow in rivers constitute a major source of breaks in ecological continuity. Given the vast array of regulatory requirements, notably the Water framework directive, and the many environmental issues involved in restoring the ecological continuity of aquatic environments, Onema decided to create a "tool" to assess and quantify the impacts of hydraulic structures on the free movement of fish.
