| 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... |

| The quantification and integration of ecosystem services (ES) into urban planning decisions is becoming increasingly important. However, studies that quantify and analyze the impacts in terms of ES changes are still scarce. We analyzed multiple ES provided by the landscape of the Urban Community of Bordeaux (CUB), in France, between 1990 and 2006 as a result of land use and cover change (LUCC) with Corine Land Cover and other open data. These ES were selected with the help of local stakeholders and were calculated using a spatially explicit modeling approach with InVEST and own-produced models. It was found that all ES, except erosion regulation, have decreased as a consequence of LUCC. Results also suggest that LUCC change decisions which do not consider... |

| 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... |

| 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... |

| 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... |

| 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... |

| 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... |

| In 2006, IFREMER, with the help of the polling institute BVA, implemented a national pilot study of recreational fishing. Taking into account all the different fishing methods, from shellfish gathering to offshore angling, including spear-fishing, this study was designed to provide estimates of (i) the number of recreational fishers in France, (ii) recreational fishing effort; (iii) catches and landings; (iv) the economic impacts of recreational fishing, and to develop a classification of recreational fishers. A two-part method was adopted: a random-digit-dialing (ROD) survey combined with an on-site survey. The data collected from telephone and on-site surveys were compared and then used in combination to provide a reliable estimate of this growing... |

| Marine recreational fishing (MRF) is a high-participation activity with large economic value and social benefits globally, and it impacts on some fish stocks. Although reporting MRF catches is a European Union legislative requirement, estimates are only available for some countries. Here, data on numbers of fishers, participation rates, days fished, expenditures, and catches of two widely targeted species were synthesized to provide European estimates of MRF and placed in the global context. Uncertainty assessment was not possible due to incomplete knowledge of error distributions; instead, a semi-quantitative bias assessment was made. There were an estimated 8.7 million European recreational sea fishers corresponding to a participation rate of 1.6%. An... |

| 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. |
