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). A review.

The purpose of the workshop was to facilitate discussions between European river basins on monitoring of water and aquatic environments, with the European commission and the European environment agency on hand, and to enhance the common implementation strategy for the WFD. It was an occasion to discuss monitoring results and the impact of monitoring on implementation of management plans and programmes of measures in 3 main fields, namely the purposes of the monitoring programmes, stakeholder organisation and roles, and monitoring strategies.

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.

Local governments are frequently confronted with the problem of managing agricultural nonpoint-source pollution. This type of pollution is one of the main causes of the degradation of water bodies in France and Europe. How can its management be improved and its impacts reduced? What are the tools and methods now available to water managers to effectively counter the pollution?

The objective of the meeting, based on an analysis of wetland research over the past 10 years, was to set guidelines for scientific policy on wetlands better suited to the needs expressed in the field. This document reports on that meeting.

The 3^rd workshop " Water science meets policy " focused on demonstrating the added value of the science-policy interface (SPI) at all geographical levels and proposing key aspects to implement a sustainable SPI activity in the CIS structure. This document presents the main recommendations expressed by the participants regarding tools, methods and operational modalities for an efficient implementation and successful SPI in the WFD CIS context.

The Water framework directive has made the physical restoration of aquatic environments an essential component in public water-management policies. The document proposes a comprehensive framework with a description of the tools that may be used in an overall strategy designed to accompany stakeholders wishing to launch a hydromorphological-restoration project and ensure its success.

The national symposium on monitoring and reducing chemical contamination of aquatic environments brought together water managers, stakeholders and scientists. An array of results and techniques, produced over 5 years of intensive efforts by BRGM, Ifremer, Ineris and Irstea, were presented.

This book presents definitions, information and a discussion on the economic-analysis techniques used to manage water and aquatic environments. The goal is to assist in the operational implementation of economic analysis.

This document presents the results of the first National meetings on invasive exotic crayfish providing a description of present knowledge on invasive and native crayfish species in France, a better understanding of processes operating, the place of invasive crayfish in aquatic ecosystems and their effects on biodiversity, and lastly a presentation of management approaches investigated in the country.
