| Le programme d'amélioration des techniques d'élevage de la Chevrette Macrobrachium rosenbergii en Guyane constitue la deuxième phase du programme d'expérimentation mené sur la station IFREMER de Kourou. Jusqu'en 1988, l'effort a porté sur l'analyse du système continu classique utilisé par l'ensemble des producteurs de Macrobrachium aux Antilles et en Guyane. A partir de 1988, il apparut que la résolution des problèmes posés par son application passait par l'utilisation de schémas de gestion de la population en mode discontinu. Les expérimentations ont donc porté sur les principales conditions d'élevage susceptibles d'améliorer l'efficacité du schéma d'exploitation de la population. En prégrossissement, il s'agissait d'obtenir le meilleur compromis... |

| En 1987, la filière de production de chevrettes Macrobrachium rosenbergii en Guyane Française a fait l'objet d'intervention du laboratoire d'aquaculture de l'IFREMER à 2 niveaux : un appui technique à la profession, et des expérimentations à la station expérimentale gérée en commun par IFREMER et INRA, à KOUROU. L'appui technique a porté sur la formation d'éleveurs notamment pour le démarrage des exploitations, l'amélioration des techniques d'exploitation et de choix des classes détaillées commerciales, la maîtrise des caractéristiques du milieu d'élevage par l'utilisation des amendements classiques, la lutte contre la contamination des produits par les germes coliformes. Le programme de recherche a porté en 1987 sur l'analyse du milieu d'élevage et tenté... |

| L'accélération des changements dans tous les domaines, qu'il s'agisse d'environnement, de technologies ou de la vie des sociétés humaines, est une donnée majeure de notre temps. Jusqu'au XIXe siècle, les hommes gardaient une relative maîtrise des révolutions, qu'elles soient techniques (la vapeur, l'électricité, l'atome, ... ) ou sociales (la démocratie, le communisme, etc). A la fin du XXe siècle, la complexité des sociétés humaines, le foisonnement des découvertes scientifiques rapidement exploitées par l'industrie à des fins économiques et l'interdépendance croissante de toutes les activités dans des écosystèmes fragilisés ont conduit les communautés humaines à davantage subir les révolutions: mondialisation d'une économie de plus en plus immatérielle,... |

| Aquaculture is one of the main supply of protein in feed for mankind, notably in Asia. It increases and had exceeded the level of production of world fisheries, which is decreasing. According to sites and rearing methods, aquaculture contributes to add value but also in some cases to impact negatively the aquatic ecosystems. In the coastal area, a rich and productive zone, but also a place of conflicts, this activity presents a high potential for development if it takes into account the rules of sustainability. The conditions of this sustainability may be cleared with appropriate methods of foresight analysis applied for each development project. The analysis of the professional experience of D. Lacroix for 33 years in aquaculture is structured in three... |

| Le congrès annuel de l'EAS (European Aquaculture Society) a rassemblé pendant 4 jours 531 chercheurs, producteurs et responsables institutionnels de 47 nationalités. Il a donné lieu à la présentation de 105 communications orales et de 274 posters. La thématique générale du congrès était construite sur le thème général suivant: Biotechnologies for quality. Il s'agissait de montrer que les biotechnologies, qui font parfois peur au consommateur comme au citoyen, constituent un outil privilégié de développement de l'aquaculture, y compris dans les aspects de développement durable. De fait, aujourd'hui, les attentes du grand public restent centrées autour des notions de qualité, sécurité, bien-être et santé animale. Le représentant de la Commission européenne a... |

| This conference was the second step of a long development process launched in Kyoto, in 1976, first trial to estimate the potential of aquaculture, recent but promising activity. Progress made by aquaculture have stressed F AO to organise an overview of this activity with an ambitious goal: to establish the frame of a sustainable development for the next 25 years. For that purpose, FAO, supported by NACA network welcomed 600 scientists from 72 countries during 5 days in Bangkok in order to screen all aspects of aquaculture development: legal frame, scientitic research, technical transfer, extension services, education & training, socio-economics, etc. The conference was managed as a FAO workshop: keynote speeches, specialised sessions concluding in... |

| This article calls back first of all a set of facts relative to the main stakes considering sea and ocean so much on the economic point of view, in the scientific technological and innovative fields, in the governance aspects as also in the culture and international prestige ones. Then the article synthesizes several of the elements of the European study on the blue growth, the established priorities, the results of the study and its recommendations. The case of New Caledonia is then analyzed which shows that considering the 11 economic priorities identified by the European Union, 10 interest or may interest this ultra-marine country. A focus is proposed on a second European study which concerns the implementation of a Blue Society (Sea for Society... |

| Integrated Coastal Zone Management (ICZM) is a link between three main fields: environment, society and economics. All of them are under strong and contradictory pressures with numerous factors and limited up-to-date and consistent knowledge. Nevertheless, decision makers have to find methods and means to manage the sustainable development of the coastal area, a place where different and frequently conflicting uses are steadily increasing, notably along the Mediterranean coastline. Numerous guidelines are available but their usual and common sense recommendations are rarely applied. The actor-network theory (Callon & Latour) could be a useful tool to clarify and reduce chronic resource use conflicts in coastal areas. The usefulness and efficiency of... |

| Due to favourable environmental conditions and political will, marine fish farming has developed recently around the Mediterranean. The Mediterranean area is characterised by a large number of islands which are extremely diversified from geographical, political or socioeconomic point of views. As a matter of fact, it turns out that almost a third of the Mediterranean fish farming production comes from these islands which have proven to offer good conditions for the development of that new activity. The reasons why somany enterprises have been established on islands are very diverse. Taking advantage of good environmental conditions is the most common motivation, since islands are usually less submitted to constraints due to town extension, industry... |

| The perception of ocean areas by policy-makers or by people, living or not on the coast, has significantly varied over centuries. Due to its vastness and complexity, the sea has been studied within distinct academic disciplines. However, the current issues related to the sea, such as climate change, marine pollution or coastal tourism, require an integrated vision of the assets and drawbacks in order to meet the challenges arising from human activities both at sea and onshore. In this study, a group of foresight officers from the French network of public research institutes decided to cross-check and compare several science approaches (biology, sociology, economics, etc) about oceans. Thus, 11 sectors of maritime activity (transportation, fisheries,... |

| In October 2019, AllEnvi [the French National Alliance for Environmental Research] published the findings of a foresight study on the environmental, social and economic consequences of rising sea levels — one of the direct manifestations of climate change — in the years to 2100 and the way we might anticipate these consequences and prepare for them. That exercise, based on the scenario-building method, enabled eight general scenarios and three territorial focuses to be developed. Denis Lacroix and Nicolas Rocle outline its main lessons here. After first going into the framing, methodology and context involved, they present the scenarios in three family groups (‘Coastal adaptation’, ‘Denial’ and ‘Fragmented World’), together with the territorial focuses... |

| L’interface terre-mer, prise au sens large, est un espace fragile, convoité et soumis à de multiples pressions sans qu'il n’y ait de vision d'ensemble des populations et des activités qui s'y développent, ni de maîtrise globale des multiples décisions concernant ce milieu. Or la montée du niveau de l'océan apparaît comme une des pressions majeures de ce siècle. Son ampleur et ses effets à long terme sont difficiles à identifier, et donc, à anticiper. Toutefois, si les causes sont encore incomplètement analysées et comprises, les premiers effets sont déjà observables sous diverses formes et sur de nombreux sites. Les impacts de cette élévation sont encore faibles aujourd'hui, mais les projections portent à penser que l’élévation du niveau de la mer va... |
