This guideline is designed as a toolkit to support stakeholders and designers in the completion of constructed wetlands (CW) projects in tropical and equatorial climate zones.

This guide sums up the currently available knowledge on setting up buffer zones to limit the transfer of farm substances (pesticides, nutrients) to aquatic environments.

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.

Questions concerning littoral wetlands are being raised during a time of transition impacted by both natural phenomena (e.g. the infl uence of climate change on littoral wetlands) and institutional changes. In this highly fl uid context, the objective is to produce a joint project for the Atlantic, Mediterranean and Channel/North Sea coasts, based on a shared vision of the issues.

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.

In terms of the specific water framework directive (WFD) needs, can coral reefs and seagrasses serve as indicators suited to assessing the ecological status of water bodies? The development of such tools represents a scientific challenge given the paucity of available knowledge on the ecology and functioning of these tropical ecosystems, and the relative lack of experience in their assessment.

In a few months, France will have its very own National Centre for river restoration, like a number of other European countries. In order to collectively consider this centre’s priority activities, Onema organised a day of discussion with the relevant public-sector stakeholders on 1 December 2015 in Paris.

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.
