Little work dealing with the evaluation of aquaculture system sustainability has so far been undertaken on a global and comparative basis. Moreover, such work is mostly based on very unbalanced approaches in terms of the dimensions of sustainable development that are taken into account. The approach adopted in this article is designed to encompass all the dimensions of sustainability including the institutional one (governance). The taking into account of this latter, in particular, together with the role played by aquaculture in sustainability at the territorial level gives the approach its original and innovative nature. The process of establishing the checklist of sustainability indicators in aquaculture relies on a hierarchical nesting approach which...

An approach to co-construct sustainable development indicators in aquaculture
Provedor de dados: 5
Autores: Rey-valette, Helene; Clement, O; Aubin, Joel; Mathe, Syndhia; Chia, Eduardo; Legendre, Marc; Caruso, D; Mikolasek, Olivier; Blancheton, Jean-paul; Slembrouck, J; Baruthio, Aurele; Rene, Francois; Levang, Patrice; Morissens, Pierre; Lazard, Jerome.
It cannot be said that aquaculture has ignored sustainable development (SD), judging by the number of standards, guides and indicators devoted to it, produced mainly under the aegis of international organizations such as FAO, The European Union and sorne NGOs. However, these continue to be perceived in large measure as constraints rather than as shared objectives by actors. Faced with this situation, which is not specific to aquaculture but on the contrary quite general regardless of sector, context or scale, the authors seek to propose a generic approach that through a collective process, i.e. a co-construction, promotes the implementation and appropriation of SD. What makes this approach original is not only the participatory nature of the construction,...

The new sustainable development data repository requires new analysis grids, in particular for factors accounted for in productive system typologies. This paper, based on the aquaculture example, analyses the diversity in aquaculture systems with respect to sustainable development. Various typologies are obtained by evaluating structural and functional approaches integrating variables related to production and regulation systems and to the territorial insertion of fish farms. Categories have been defined on a scale based on a set of five sites, which are representative of a wider range of aquaculture systems. Use of these categories goes beyond the local typologies and prepares a generic meta-typology classification for the systems. This generic...

Guide méthodologique d’aide à la prise en compte des problématiques maritimes dès le diagnostic des SCOT côtiers
Provedor de dados: 5
Autores: Rodriguez, Thibault; Fourrier, Adeline; Mazouni, Nabila; Rey-valette, Helene; Roussillon, Jean Philippe; Laugier, Thierry; Loubersac, Lionel.
After a reminder on the program SYSCOLAG (Coastal and Lagoons Systems), of the regulatory and legislative context in territorial economic planning on the coast, we describe the structure of the developed methodological tool. We clarify then the method according to its three main trunk roads: effects of the activities and uses on the economy of the territory, the effects of the activities and uses on the natural environment and the living environment, the evaluation of the interactions between activities and uses. We apply the method exposed in a frame demonstrator by taking the scenario of the lagoon and coastal territory of the Thau Basin (Hérault). A set of appendices, including in particular evaluation grids are supplied with support for the...

Restoration ecology of coastal lagoons: new methods for the prediction of ecological trajectories and economic valuation
Provedor de dados: 5
Autores: De Wit, Rutger; Rey-valette, Helene; Balavoine, Juliette; Ouisse, Vincent; Lifran, Robert.
Conservation of the seven lagoons of the Palavas complex (southern France) has been severely impaired by nutrient over-enrichment during at least four decades. The effluents of the Montpellier wastewater treatment plant (WWTP) represented the main nutrient input. To improve the water quality of these lagoons, this WWTP was renovated and upgraded and, since the end of 2005, its effluents have been discharged 11 km offshore into the Mediterranean (total investment €150 M).   Possibilities of ecosystem restoration as part of a conservation programme were explored by a focus group of experts. Their tasks were: (i) to evaluate the impact of the reduction of the nutrient input; (ii) if necessary, to design additional measures for an active restoration programme;...

Vingt ans d’aquaculture en Afrique du Nord : évolutions, bilan critique et avenir
Provedor de dados: 5
Autores: Kara, Mohamed Hichem; Lacroix, Denis; Sadek, Sherif; Blancheton, Jean-paul; Rey-valette, Helene; Kraiem, Mejdeddine.
This paper presents the evolution of aquaculture in North Africa during the 20 last years, and the assets and bottlenecks for each country. This work uses the results of the European project Aquamed (2011-2013). The analysis of the evolutions of this sector, including research and development allows to establish a diagnosis on the strengths and the weaknesses in the four countries (Morocco, Algeria, Tunisia and Egypt). The retrospective analysis helps in identifying solutions for a more sustainable development. It also contributes to select priorities for action in a long-term vision (2035). This double overview, on the past and the future, should help decision-makers and experts to identify the best politics for a sector, which has a high potential in the...

Modeling economic vulnerability: As applied to microbiological contamination on the Thau Lagoon shellfish farming industry
Provedor de dados: 5
Autores: Perez Agundez, José A.; Yimam, Eden; Raux, Pascal; Rey-valette, Helene; Girard, Sophie.
The economic impacts induced by the harmful effects of pollution or negative natural events are heterogeneous and depend on the event type and intensity, as well as the characteristic make-up of agents affected. This vulnerability analysis evaluates how each agent (or group of agents) is potentially affected by an external stress or event with respect to risk of exposure, sensitivity or intensity of subjection, and coping capacity of these agents in order to avoid or reduce its effects. Using a comparative formulation model, the aim of this paper is to quantifiably assess the vulnerability of shellfish farming linked to bacteriologic pollution. An analysis of the vulnerability concept and the construction of pertinent indicators are presented. The analysis...

Autores: Mathe, Syndhia; Aubin, Joel; Wilfart, Aurélie; Rey-valette, Helene; Slembrouck, Jacques; Ediwarman,; Fontaine, Pascal; Tocqueville, Aurélien; Blancheton, Jean-paul; Callier, Myriam.
Identification of relevant social impact indicators for a Social Life Cycle Assessment (SLCA) is still difficult and poorly documented (Jorgensen, et al, 2009). In aquaculture systems, the studies based on social aspects are essentially focused on manpower or on conflicts with other activities . In the PISCEnLit project**, we aim to broaden the vision of social impacts of fish farming systems using a new approach of SLCA. We studied fish farming pond systems in France (Lorraine and Brenne) and Indonesia (Tangkit Baru and Kumpeh Ulu in Sumatra island). In this study, we focused on the choice of the impact categories using the participation of stakeholders (James et al., 2002) by the identification and selection of the relevant social impacts to be assessed....

Aquaculture system diversity and sustainable development: fish farms and their representation
Provedor de dados: 5
Autores: Lazard, Jerome; Baruthio, Aurele; Mathe, Syndhia; Rey-valette, Helene; Chia, Eduardo; Clement, Olivier; Aubin, Joel; Morissens, Pierre; Mikolasek, Olivier; Legendre, Marc; Levang, Patrice; Blancheton, Jean-paul; Rene, Francois.
Initiatives for the sustainable development of aquaculture have so far focused on the production of codes of conduct, of best management practices, of standards etc., most of which have been developed by international organisations, the industrial sector and non governmental organisations. They were, to a large extent, produced using a "top down" process and inspired by models from intensive industrial shrimp and sea fish farming (mainly salmon). However, most of global aquaculture production comes from small-and medium-sized farms, essentially in Asia which contributes 92% of the total world aquaculture production volume. The objective of this article is to define the contours of systemic typologies that are able to express the sustainability conditions...

Is sustainable development a motor or a constraint for the professionalization of the pearl oyster industry in tahiti?
Provedor de dados: 5
Autores: Rey-valette, Helene; Lacoste, Elise; Perez, Jose; Raux, Pascal; Gaertner, Jean-claude; Gaertner-mazouni, Nabila.
This article reports the results of a survey of the pearl oyster industry in French Polynesia territory. Its purpose is to examine the perceptions of the priorities for the development of this industry towards sustainable development. These perceptions were apprehended by a survey of pearl oyster farmers and other stakeholders of the sector (management authorities, scientists). After describing the methodological protocol of these investigations, it comes to confront the priorities chosen by professionals (i.e. pearl farmers) concerning sustainable development, with the perceptions of others stakeholders in the sector. Secondly it comes to build a typology of the priorities of pearl farmers concerning sustainable development. This analysis enables the...
