| Sustainability is said to be the science of integration, be it integration of scale, discipline or of stakeholders' interests. One way to integrate such diverse elements is to develop sustainable development indicators. Numerous national and international organizations have attempted to develop such indicators, among which interaction indicators are of critical importance because they enable us to link up human activities, ecological dynamics, and social goals. Among the various ways to develop such indicators, the most common ones are the pressure-state-response (PSR) indicators, as well as others coming from this framework. With realistic methodology one shall observe how PSR indicators might appear as an operational tool to face rapid social and... |

| 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... |

| There are two ways of assessing the costs of environmental degradation: as the costs associated with the loss of benefits resulting from the degradation of natural capital, and as the maintenance costs required to compensate for the actual or potential degradation of natural capital. The first of these methods is based on the Total Economic Value (TEV) of benefits forgone because of the depletion of ecosystem services delivered by marine biodiversity. The second method is based on the costs required to maintain a good state of marine biodiversity, one which makes it possible to deliver ecosystem services. This paper gives an illustration of this second approach. It details how these maintenance costs have been calculated in the initial assessment of the... |

| At the national level, with a fixed amount of resources available for public investment in the restoration of biodiversity, it is difficult to prioritize alternative restoration projects. One way to do this is to assess the level of ecosystem services delivered by these projects and to compare them with their costs. The challenge is to derive a common unit of measurement for ecosystem services in order to compare projects which are carried out in different institutional contexts having different goals (application of environmental laws, management of natural reserves, etc.). This paper assesses the use of habitat equivalency analysis (HEA) as a tool to evaluate ecosystem services provided by restoration projects developed in different institutional... |

| 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.... |

| According to the Convention on Biological Diversity (CBD), states have to provide indicators in order to assess the performance of their initiatives for halting the loss of biodiversity. Sixteen headline indicators have been identified for monitoring the CBD targets. Of these indicators only one, "Trends in the abundance and distribution of selected species," is a direct headline indicator of "non-exploited" biodiversity. In France, the implementation of this indicator is completely dependent on data collected by volunteers. Since this investment of volunteer time is equivalent to savings in administrative costs, we attempt in this paper to assign it a monetary value. This enables us to estimate how much the French administration saves thanks to volunteer... |

| 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... |

| 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 . |

| This short paper presents the approach which has been implemented in France for estimating the costs of ecosystem degradation in the context of the Marine Strategy Framework Directive (MSFD). Among the possible approaches, forgone benefits assessment or maintenance costs assessment, France decided to use the latter. The paper contains an introduction, a section which explains how to choose an economic approach coherent with the MSFD rationale, a section which exposes the methodology developed for implementing the approach, and a section on the main results. |

| 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... |

| For many conservation scientists, interdisciplinarity and participation can be efficient in the management of biodiversity. For both methods, new tools and new participative processes such as the so-called co-modeling process are required. The key questions addressed in this article are how group dynamics shape the model and why certain perspectives dominate in a process designed to be democratic. It is necessary, therefore, in order to appreciate the design and the legitimacy of the model that has been co-constructed, to address the questions of both the stakeholders' interests and their status in the process. Our case study is a co-modeling program based in a French biosphere reserve. It enabled us to highlight the key role of the mediator who had to... |

| 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... |

| 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... |
