| Between 2006 and 2008, Ifremer, in collaboration with the polling institute BVA, implemented a pilot survey of french recreational fisheries. The aim of the survey was to assess the overall population involved in this activity, taking into account the diversity of recreational fishing practices, from fish and shellfish gathering on the seashore to angling and spearfishing. The study was designed to provide first estimates of fishing effort, catches and landings, and economic impacts of recreational fishing. The protocol implemented was two-step. First, a telephone survey of french households, based on a sampling frame of the entire french population of people aged 15+, was carried out to assess the population of fishers and give a first general view of the... |

| Citizen science, defined as participation of the general public in scientific research, could significantly help scientists to address biodiversity issues, through (i) monitoring the state of biodiversity, (ii) framing indicators which synthesise and communicate information on the state of biodiversity, (iii) building scenarios to evaluate the plausible consequences of different policies. A key asset of citizen science is that participating citizens disseminate the information they gain, thereby increasing the profile of issues being researched. We review further benefits associated with biodiversity monitoring, indicators and policy scenarios, envisioned as collaborative tools between scientists and citizens. Such collaboration promotes both the... |

| French regulations concerning the mitigation of development impacts have been progressively strengthened with offsets now required for impacts on forests, wetlands, and protected species, among others. In 2012, following a national consultative process called Grenelle de l’Environnement, legal requirements in terms of monitoring and effective implementation of measures aimed at avoiding, reducing and offsetting impacts were strengthened. This has created strong “demand” for offsets. The workability of these new requirements has come under scrutiny, not least because of their strong legal and financial implications for developers. In this context, official government guidance on implementing the mitigation hierarchy was published in 2012. Under this... |

| The report presents a survey of marine related activities in France and an assessment of their economic weight in terms of value added and employment estimates. A brief outline of the recent past and present economic situation of these activities, and of their position on international markets is given. The survey presents the commercial sector, including marine resource exploitation, manufacturing activities and services, followed by the public sector, including the Navy, state intervention at sea, coastal environment protection and marine sciences. A summary gives an overall estimation of marine value added and employment. |

| Bien gérer les activités humaines et les ressources naturelles côtières nécessite de connaître de manière précise les interactions entre elles. A l'heure actuelle, la pêche professionnelle est relativement bien suivie, mais ce n'est pas le cas de la pêche récréative. En effet, cette activité est difficile à caractériser et à renseigner car elle renvoie le plus souvent à des pratiques nomades, dispersées et très hétérogènes, pour lesquelles les informations sont rares . |

| The growth of marine recreational activities raises the issues of the current lack of knowledge on these activities and the information required to assess their potential impacts. Indeed, the monitoring of unrecorded activities is a great challenge, especially when basic information, such as the size of the population practicing the different activities, is unknown. In this paper, the experience of the monitoring of marine recreational fishing was used to carry out a diagnosis study to assess the cost-effectiveness of survey methods used in France between 2004 and 2012. Costs of alternative surveys were balanced with data quality, and particular attention was paid to potential biases. Results showed that the involvement of citizens through diary surveys... |

| In the context of the Water Framework Directive, the French Water Agencies were asked to justify exemptions, for disproportionate cost reasons, to the “good water” status in a series of river basins in 2015. The ministry of the Environment and the economists of the Water Agencies agreed on the fact that this justification would be based on cost-benefit analyses. A great number of cost-benefit analyses were carried out on water bodies or groups of water bodies. This article reports on this experience conducted by the French Water Agencies. It highlights the fact that the large majority of restoration projects generated higher costs than benefits. It suggests that the implementation of the Water Framework Directive could be considerably limited by the use of... |

| While economic valuation of ecosystem services (ES) is widely acknowledged as a tool to support decision-making processes, studies have also shown that there exists a literature blindspot on the effective use of economic valuation (Laurans et al. 2013; Marco ne and Mongruel 2014). The VALMER project seeks to bridge this gap between theory and practice by looking at how ecosystem services assessment (ESA) can support marine management and planning. Natural scientists, economists and marine environment managers from various institutions undertook ESAs in six pilot sites over the two sides of the Channel. The objectives of this paper are to share some results of two French ESAs, and to discuss issues and perspectives of ESAs from a marine management... |

| Natura 2000 (N2K) is a European network of protected areas that has grown out of the implementation of the Birds Directive (1979) and the Habitats Directive (1992). To date, the literature focussing on “conservation measures” required by the directives has been scarce. This article contributes to a better understanding of associated practices with regard to these measures in the case of France. We put forward a quantitative approach based on 1378 “action-sheets” randomly extracted from 113 management documents of French Natura 2000 coastal sites. These action-sheets are considered to be the physical embodiment of the notion of the conservation measure itself. The analysis concentrates on the “type” of the proposed measures, expressed in terms of a... |

| Le gouvernement français s’est engagé à travers différentes conventions et textes institutionnels à stopper d’ici 2010 la perte de la biodiversité. Pour atteindre cet objectif, le Ministère de l’Ecologie, de l’Energie, du Développement Durable et de la Mer (MEEDDM) a mis en place le Système d’Information sur la Nature et les Paysages (SINP), afin de rassembler et structurer l’information sur le patrimoine naturel et la biodiversité. Le volet marin de ce système, le SINP mer, a également pour vocation de valoriser ces informations, soit de présenter des indicateurs permettant de répondre aux enjeux de conservation de la biodiversité marine à partir des données contenues dans le système. Ce document présente la première phase de travail sur les indicateurs... |

| The European Union׳s energy policy aims to increase the proportion of energy derived from renewable sources in Europe. Marine renewable energy, offshore wind energy especially, contributes to the renewable energy mix. Offshore wind farms appear to be clean, and are supported by governments and NGOs as a way to reduce the use of conventional energy resources and thus decrease greenhouse gas emissions. However, developing infrastructure in marine areas can impact marine ecosystems. European directives ask offshore wind farm developers to carry out an Environmental Impact Assessment (EIA) including a mitigation hierarchy, i.e. envisaging measures that would avoid, reduce, and if possible offset significant adverse effects on ecosystems and human activities.... |
