Analyse des stratégies d'occupation du domaine maritime côtier : le cas des concessions conchylicoles. Rapport final du projet ASTRODOME ArchiMer
Mongruel, Remi; Perez Agundez, José A.; Girard, Sophie; Bailly, Denis; Nassiri, Abdelhamid.
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...

Droits à produire transférables : Le marché des concessions conchylicoles et ses effets non désirés ArchiMer
Mongruel, Remi; Perez Agundez, José A.; Girard, Sophie.
This paper sets out an historical analysis of the rights-based system applied to the French shellfish-farming sector and a study of the current operating way of this system. It addresses the issue of the distribution of production means within an industry whose two main characteristics are the familial exploitation model and the specific social objectives like jobs creation in some coastal areas. The shellfish farming rights-based system has evolved toward a transferable production-rights system. However, the spontaneous emergence of a market for production-rights in the context of a weak administrative intervention is likely to generate unintended effects, whose occurrence is tested using quantitative and qualitative data. The final discussion searches...

Modeling economic vulnerability: As applied to microbiological contamination on the Thau Lagoon shellfish farming industry ArchiMer
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...

Modeling soft institutional change and the improvement of freshwater governance in the coastal zone ArchiMer
Mongruel, Remi; Prou, Jean; Balle-beganton, Johanna; Lample, Michel; Vanhoutte Brunier, Alice; Rethoret, Harold; Perez Agundez, José A.; Vernier, Françoise; Bordenave, Paul; Bacher, Cedric.
The contribution of soft institutional change to improve freshwater governance in the coastal zone will be examined. Freshwater management seeks to reduce losses due to overexploitation of the common-pool resources provided by river catchments and their associated ecosystems. Due to the complexity of the governance system, improving the performance of one coastal social-ecological system means searching for the appropriate “soft” institutional change. In the Pertuis Charentais region, increasing scarcity of freshwater in summer threatens the health of the coastal ecosystem and the sustainability of human activities, which depend on the use of natural resources. The allocation of freshwater among competing uses or concerns is a core issue for integrated...

Quantification of interdependencies between economic systems and ecosystem services: An input-output model applied to the Seine estuary ArchiMer
Cordier, Mateo; Perez Agundez, José A.; O'Connor, Martin; Rochette, Sebastien; Hecq, Walter.
The aim of this paper is to assess the possible contribution of an input-output model towards two of the basic principles of the sustainability strategy of integrated coastal zone management (ICZM) and Post-Normal Science. According to these principles, decision-support tools should offer a holistic perspective and handle high uncertainty. The difficulties in reaching sustainability are due partly to the prevailing use of "narrow-system-boundary" tools that are non-holistic. Consequently, they fail to capture important ecosystem services and ignore interdependencies between them. To comply with the basic principles, our method allows environmental assets to be evaluated in multiple units and integrates results from recent researches in natural sciences....

Technological adaptation to harmful algal blooms : socioeconomic consequences for the shellfish farming sector in Bourgneuf Bay (France) ArchiMer
Perez Agundez, José A.; Raux, Pascal; Girard, Sophie; Mongruel, Remi.
The economic impacts of harmful algal blooms (HABs) on the shellfish farming sector depend on their frequency, duration and intensity. Safeguarding storage and accelerated detoxification are technical solutions that could mitigate the effects of these events. This article first analyzes the economic feasibility of the technological changes that can be adopted by the shellfish farming sector in France. It then examines their associated social impacts. Finally, an application is carried out on the Bourgneuf Bay production area. The economic analysis addresses three issues related to HABs: (1) the economic performance of the shellfish farms in Bourgneuf Bay, (2) the costs of these new technologies, and (3) the economic viability of such an investment. Results...

Why, how, and how far should microbiological contamination in a coastal zone be mitigated? An application of the systems approach to the Thau lagoon (France) ArchiMer
Mongruel, Remi; Vanhoutte-brunier, Alice; Fiandrino, Annie; Valette, Francois; Balle-beganton, Johanna; Perez Agundez, José A.; Gallai, Nicola; Derolez, Valerie; Roussel, Sebastien; Lample, Michel; Laugier, Thierry.
This paper describes the building of an integrated simulation tool based on a systems approach, and its contribution to local political discussion of the mitigation of microbiological contamination of the water in a coastal area. Local management schemes view water quality as a high-priority environmental objective. In practice, how far this objective is achieved depends on trade-offs between the costs of improved water treatment facilities and the acceptable impacts of water contamination. An in-the-field experiment in collaboration with local managers was carried out in the Thau lagoon on the French Mediterranean coast during the SPICOSA (Science and Policy Integration for Coastal System Assessment) project, from 2007 through 2011. It consisted of...
