| El mercado de la tilapia de la región Sotavento del Estado de Veracruz, México se caracteriza por tener una producción y venta locales, en el cual participan agentes que la trasladan a sus lugares de origen y la ofrecen viva al consumidor; utilizando sistemas de acuicultura para su mantenimiento. Sin embargo no existe evidencia que permita identificar las características que los distinguen y su grado de influencia en la cadena productiva. El objetivo de la investigación fue el de identificar las características de los agentes minoristas que participan en el mercado de tilapia viva en la región para construir una tipología que los distinga. Para extraer la información de las poblaciones de productores de tilapia y comercializadores de tilapia viva, se... |

| In the context of accelerated global change, the concept of resilience, with its roots in ecological theory and complex adaptive systems, has emerged as the favored framework for understanding and responding to the dynamics of change. Its transfer from ecological to social contexts, however, has led to the concept being interpreted in multiple ways across numerous disciplines causing significant challenges for its practical application. The aim of this paper is to improve conceptual clarity within resilience thinking so that resilience can be interpreted and articulated in ways that enhance its utility and explanatory power, not only theoretically but also operationally. We argue that the current confusion and ambiguity within resilience thinking is... |

| With sustainability within food systems becoming an increasingly important issue, several approaches that claim to assess the sustainability of farms, farming systems, and supply chains have been developed. Looking more closely at these sustainability impact assessment approaches, we discerned considerable differences between them in terms of scope, the level of assessment, and the precision of indicators used for impact assessment. Our aim was to classify and analyze a range of available sustainability impact assessment approaches with respect to scope and precision. From a total of 35 sustainability assessment approaches, we selected 6 for a detailed comparison. From our analysis, we concluded that there are 3 different types of trade-offs in these... |

| In the domain of climate change adaptation, joint knowledge production (JKP) through intensive cooperation between scientists, policy-makers, and other actors is often proposed as a means to reconcile supply and demand for knowledge. Regional adaptation projects in the Netherlands form prominent examples of this. However, there is a lack of systematic empirical studies on how JKP can be done successfully. Here, we take the next step toward generating design principles for JKP. We do so by carrying out a comparative analysis of six Dutch adaptation projects using a previously developed assessment framework. Project documents were studied, and 30 semi-structured interviews were held with researchers, policy-makers, and financiers in the projects. Based on... |

| This study explores and interprets relevant literature to construct a typology of benefit sharing arrangements for the governance of social-ecological systems in developing countries. The typology comprises three generic categories of benefit sharing arrangements: collaborative, market-oriented, and egalitarian. We contend that the three categories provide a useful basis for exploring and classifying the different societal arrangements required for governance of social-ecological systems. The typology we present is founded on a related set of explicit assumptions that can be used to explore and better understand the linkages among ecosystem services, benefit sharing, and governance. Issues that are strongly related to sustainability in developing countries... |

| Collecting hydrological observations over the whole Bay of Biscay continental shelf can require several weeks. As a result, the observations are not truly synoptic and the interpretation of hydrological structures is corrupted by the time-lags between observations at distinct locations. We evaluated the effects of non-synoptic sampling during a spring cruise (17 April to 13 May 2000), using outputs from 3D hydrodynamic models as a substitute for true synoptic sampling. We developed a method for clustering hydrological regions based on the vertical structure of the water column and temporal changes in hydrography. In parallel, outputs from the 3D model were compared with field observations. The results show that in spring 2000 the Bay of Biscay continental... |

| A complex set of hydrodynamical structures co-exist over the Bay of Biscay continental shelf. These structures, which can spread over a limited spatial range (10s of km) and last for periods ranging from days to months, influence the rates and nature of biological production. They need to be accurately described before the mechanisms linking hydrodynamics to production can be unraveled. Such description generally requires not only 3D observations of hydrological fields (temperature, salinity, density), but also a description of how these fields vary with time. This is hardly achievable with current means of field observation but can be mimicked by hydrodynamic model simulations. Using simulations from a 3D hydrodynamic model, we developed a methodology... |

| 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... |

| Coastal Mediterranean lagoons are often defined as homogeneous ecosystems that home many migratory and sedentary species. They also host strong salinity gradients, depth variation and very diverse plant communities, which create small-scale heterogeneity within lagoons. This is why each lagoon must be described as an entity by itself made up of a multitude of homogeneous features, called habitats, which support specific ecological functions for organisms (nursery, feeding, protection against predators...). Although many studies have resulted in collecting high numbers of physical, chemical and biological data in coastal Mediterranean lagoons, there is currently a lack of knowledge of the spatial distribution of these habitats. In our project, we (1)... |

| This work aims to describe fishing activity in Guadeloupe through a typology. The samply unit y is the landing represented by a profile of specific composition. Using multivariate analysis methods allows to synthesize this fishing multi specises and multi fishing tackles. Principal Component Analysis and classification regroup landings. Then, segmentation method separateses classes by species composition. Typology is obtained by association of classes and tackles. The contraist between landings of reef fishes realized with traps and those which search for pelagics is clearly shown. Landings of queen conch and landings without fishes are separated in two classes. |

| This document presents a comparative assessment of six triennal analysis carried out between 1986 and 2002, on 1300 boats, on average, from the 35 ports of Southern Bay of Biscay fishing fleets (from Loire river to Spanish border). Fisheries statistics allow the identification of different fishing practices and fishing boats associated with them within the fleets. In order to allow comparison and analysis of the evolution that has taken place during the study period, the same variables (gears used, landed species) and multivariate analysis procedures have been used to produce groupings of vessels. Over the period, 11 components, on average, have been identified, grouped in two entities, mobile and fixed gears. If the discriminative characteristics... |

| Introduction: Setting up a policy of coastal fisheries management goes through a preliminary stage of understanding the dynamics of the fishing fleets as much as their tactics. Small fleets, such as those of the Côtes d'Armor, are characterised by: - the boats' home ports are scattered widely, - the heterogeneousness of the types of vessels and fishing gear used, - the versatility of the fishing units, - the plurispecificity of the exploited resource, - the flexibility of operating strategies, that is, the fishing owners' ability to change occupation. However, this flexibility is limited by the availability of the resource, by the market, by the investments granted (boats, fishing materiel), as well as by "cultural" context and know-how. This... |

| The paper presents a complex framework to analyse spatially and seasonally heterogenous fisheries. Typologies based on multivariate analysis have been applied on multi-species fisheries to identify patterns in fishing effort and subsequent impacts on various species. Although the Tasmanian rock lobster fishery is a single species fishery, it displays highly variable spatial and seasonal patterns of fishing effort. Rock lobster is a stationary species, so the stock of rock lobster is heterogeneously distributed along the Tasmanian coast depending on local removal from catch. The various perturbations undergone by the stock for the past decade, (overexploitation, introduction of individual transferable quotas (ITQs), climate change) led to the reorganisation... |
