| In 1997, Robert Costanza and his colleagues published a groundbreaking study [1] that estimated the monetary value of the contribution of the world's ecosystems to human wellbeing. The methods used were cited as preliminary and received considerable criticism [2] and [3]. In two more recent peer-reviewed studies [4] and [5], the authors update the original estimates of ecosystem service value and find: (1) that original per area ecosystem service values were underestimated and (2) using these revised per area values, the total global value of ecosystem services has declined. Just under ninety-five percent of the estimated loss in ecosystem service value comes from revisions by the authors in the value estimates of marine ecosystem services. These revisions... |

| Cc rapport présente les résultats des travaux réa lisés dans le cadre du stage de formation post-doctoral effectué entre septembre 2001 ct février 2003 au sein du Service d'Économie Maritime (SEM) de l' Ifremer par Rémi Mongruel, sous la responsabilité d'Olivier Thébaud et Régis Kalaydjian. L'objectif de ce post-doctorat était d'apporter une contribution à la réflexion du Service d'Économie Maritime sur les méthodes d'évaluation économique du patrimoine naturel maritime en vue d' une application aux écosystèmes côtiers. Le cahier des charges prévoyait à la fois l'examen théorique de ces questions à partir d'une synthèse bibliographique, et la participation aux programmes dans lequel le SEM était engagé, au gré de l'adéquation des problématiques de ces... |

| One of the current major scientific challenges to sustain social-ecological systems is to improve our understanding of the spatial and temporal dynamics of the relationships between biodiversity, ecosystem functioning and ecosystem services. Here, we analyse the bundles of ecosystem services supplied by three coastal ecosystems (coastal lagoons, coral reefs and sandy beaches) along a gradient of eutrophication. Based on a state-and-transition model, we analyses the dynamic responses of ecological communities to environmental change and management actions. Although few exceptions are highlighted, increasing eutrophication in the three ecosystem types leads to a degradation of the ecosystem service bundles, particularly for nutrient and pathogen... |

| Si l’idée que la Nature rend à l’Homme des services indispensables est très ancienne, l’approche par les services écosystémiques a gagné une reconnaissance universelle avec la réalisation du Millenium Ecosystem Assessment au début des années 2000. Dans l’acception contemporaine de cette notion, les évaluations de services écosystémiques doivent avant tout servir à la mise en place de politiques ambitieuses en matière de protection des écosystèmes et de la biodiversité. Ainsi, les objectifs d’Aïchi pour 2020 fixés par la Convention sur la Diversité Biologique prévoient notamment que les valeurs de la biodiversité puissent être intégrées dans les processus de décision. L’Évaluation Française des Écosystèmes et des Services Écosystémiques (EFESE) est un... |

| The report presents a survey of marine related activities in France, highlighting recent past trends, present situation and future outlook. The commercial sector includes marine resource exploitation, manufacturing branches and services. The public sector includes the Navy, State services, environmental protection and research. A summary identifies the main factors in the development of marine activities. |

| 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... |

| 1. The ASTRODOME research project aims to study the economic aspects of the system of allocation and transmission of shellfish concessions, which is considered as an essential element in the understanding of the occupancy strategies of the coastal maritime space. Two series of questions are highlighted. The first series examines the system from a sectorial development point of view: what are the shellfish farmers' needs that the implementation of a quasi concession market satisfied, and to a larger extent, what is the contribution of the evolution of the system of allocation and transmission of concessions to the evolution of the sector's structure? The second series takes a look at the system from a collective interest point of view: to what extent does... |
