A proposed ecosystem-based management system for marine waters: linking the theory of environmental policy to the practice of environmental management Ecology and Society
O'Higgins, Tim; Scottish Association for Marine Science (SAMS), Scottish Marine Institute, Scotland; Tim.O'Higgins@sams.ac.uk; Cormier, Roland; Gulf Fisheries Centre, Fisheries and Oceans Canada; Roland.Cormier@dfo-mpo.gc.ca; Diedrich, Amy; School of Earth and Environmental Sciences, James Cook University, Australia; amy.diedrich@jcu.edu.au.
New coastal and marine management strategies have recently been developed in many countries and regions. From an ecosystem approach perspective, the aim of such strategies is the maintenance of ecosystem integrity while enabling the sustainable use of ecosystem goods and services. There is, however, a need for harmonized definitions and standardized processes to deal not only with the interjurisdictional and multidisciplinary complexities that are associated with such strategies but also with the extensive timelines and resources implicated in the planning and implementation of these strategies. The ecosystem-based management system proposed here is based on three pillars that facilitate the integration of an ecosystem approach to coastal and oceans policy...

Achieving good environmental status in the Black Sea: scale mismatches in environmental management Ecology and Society
O'Higgins, Tim; Scottish Association for Marine Science; Tim.O'Higgins@sams.ac.uk; Farmer, Andrew; Institute for European Environmental Policy; AFarmer@ieep.eu; Daskalov, Georgi; IBER-BAS;; Knudsen, Stale; University in Bergen; stale.knudsen@sosantr.uib.no; Mee, Laurence; Scottish Association for Marine Science; laurence.mee@sams.ac.uk.
The Black Sea has suffered severe environmental degradation. Governance of the Black Sea region is complex and results in a series of scale mismatches which constrain management. This paper develops a simple classification of spatial scale mismatches incorporating the driver, pressure, state, welfare, response (DPSWR) framework. The scale mismatch classification is applied to two major environmental problems of the Black Sea, eutrophication and small pelagic fisheries. A number of scale mismatches are described and classified and potential solutions are identified.

Aquaculture and marine protected areas: Potential opportunities and synergies ArchiMer
Le Gouvello, Raphaela; Hochart, Laure-elise; Laffoley, Dan; Simard, Francois; Andrade, Carlos; Angel, Dror; Callier, Myriam; De Monbrison, David; Fezzardi, Davide; Haroun, Ricardo; Harris, Alasdair; Hughes, Adam; Massa, Fabio; Roque D'Orbcastel, Emmanuelle; Soto, Doris; Stead, Selina; Marino, Giovanna.
To meet the Convention on Biological Diversity's Aichi Target 11 on marine biodiversity protection and Aichi Target 6 on sustainable fisheries by 2020, as well as the Sustainable Development Goal (SDG) 2 on food security and SDG 14 on oceans by 2030, there is an urgent need to rethink how best to reconcile nature conservation and sustainable development. This paper argues for effective governance to support processes that apply principles of sustainable development and an ecosystem approach to decide about economic activities at sea such as aquaculture. It describes opportunities, benefits and synergies between aquaculture and MPAs as a basis for wider debate. The scope is not a comprehensive analysis of aquaculture and MPAs, but rather to present examples...

Benthos distribution modelling and its relevance for marine ecosystem management ArchiMer
Reiss, Henning; Birchenough, Silvana; Borja, Angel; Buhl-mortensen, Lene; Craeymeersch, Johan; Dannheim, Jennifer; Darr, Alexander; Galparsoro, Ibon; Gogina, Mayya; Neumann, Hermann; Populus, Jacques; Rengstorf, Anna M.; Valle, Mireia; Van Hoey, Gert; Zettler, Michael L.; Degraer, Steven.
Marine benthic ecosystems are difficult to monitor and assess, which is in contrast to modern ecosystem-based management requiring detailed information at all important ecological and anthropogenic impact levels. Ecosystem management needs to ensure a sustainable exploitation of marine resources as well as the protection of sensitive habitats, taking account of potential multiple-use conflicts and impacts over large spatial scales. The urgent need for large-scale spatial data on benthic species and communities resulted in an increasing application of distribution modelling (DM). The use of DM techniques enables to employ full spatial coverage data of environmental variables to predict benthic spatial distribution patterns. Especially, statistical DMs have...

Drivers of Change in Socio-Ecological Production Landscapes: Implications for Better Management Ecology and Society
Gu, Hongyan; Shanghai Academy of Social Sciences; United Nations University Institute for the Advanced Study of Sustainability; gu@sass.org.cn; Subramanian, Suneetha M.; United Nations University Institute for the Advanced Study of Sustainability; subramanian@ias.unu.edu.
The term socio-ecological production landscapes (SEPLs) has recently gained currency in conservation circles because of a recognized need to look beyond protected areas to the management of human-influenced landscapes and ecosystems. We have drawn on a variety of case studies from Asia and other parts of the world to understand the underlying driving forces that have led to the need for greater awareness and sustainable management of SEPLs. We have analyzed the drivers of these changes from socio-political, legal, economic, and socio-cultural perspectives. The analysis shows that SEPLs contribute to local, national, and global economies, and their production and harvesting processes are subject to external demands and pressures. Policy makers should...

Ecoviability for ecosystem-based fisheries management ArchiMer
Doyen, Luc; Bene, Christophe; Bertignac, Michel; Blanchard, Fabian; Cisse, Abdoul; Dichmont, Catherine; Gourguet, Sophie; Guyader, Olivier; Hardy, Pierre-yves; Jennings, Sarah; Little, Lorne Richard; Macher, Claire; Mills, David Jonathan; Noussair, Ahmed; Pascoe, Sean; Pereau, Jean-christophe; Sanz, Nicolas; Schwarz, Anne-maree; Smith, Tony; Thebaud, Olivier.
Reconciling food security, economic development and biodiversity conservation is a key challenge, especially in the face of the demographic transition characterizing many countries in the world. Fisheries and marine ecosystems constitute a difficult application of this bio-economic challenge. Many experts and scientists advocate an ecosystem approach to manage marine socio-ecosystems for their sustainability and resilience. However, the ways by which to operationalize ecosystem-based fisheries management (EBFM) remain poorly specified. We propose a specific methodological framework-viability modelling-to do so. We show how viability modelling can be applied using four contrasted case-studies: two small-scale fisheries in South America and Pacific and two...

Effets directs et indirects de la pêche sur des groupes trophiques de poissons démersaux, définis par une approche écomorphologique ArchiMer
Reecht, Yves.
Functional groups dynamics in marine communities help understanding how perturbations impact the functioning of an ecosystem. It is notably expected that functional groups respond differently to fishing pressure owing to their direct exposure to fishing and interactions between groups (indirect effects). A method was developed, based on an ecomorphological approach focusing on predation functions, to define size- and taxonomy-driven functional groups in demersal fish communities from the Celtic Sea and the North Sea. Eleven functional traits were used to define 12 functional groups in Celtic Sea (based on measurements on 930 individuals from 33 species) and seven groups in North Sea (710 individuals from 22 species). In the Celtic Sea, the functional...

Estimates of population parameters and consumption/biomass ratio for fishes in reservoirs, Paraná State, Brazil Neotropical Ichthyology
Gubiani,Éder André; Gomes,Luiz Carlos; Agostinho,Angelo Antonio.
Consumption, natural mortality, and growth are important parameters for the construction for both fisheries and ecosystems models. We estimated k (growth constant of the von Bertalanffy's function), Loo 1(asymptotic length), Woo (asymptotic weight), Ar (caudal fin index), M (natural mortality), and Q/B (consumption/biomass ratio) for several fish species inhabiting reservoirs. We explored possible relationships among these parameters for 135 fish species sampled in thirty reservoirs in the State of Paraná, southern Brazil. Maximum length (Lmax) varied from 2.60 to 79.00 cm, Loo from 2.73 to 85.05 cm, Woo from 0.23 to 9,490.26 g, k from 0.01 to 2.38 yr-1, Ar from 0.03 to 3.60, M from 0.16 to 2.82 yr-1, and Q/B from 3.31 to 67.18. Significant correlations...

Evaluating potential indicators for an ecosystem approach to fishery management in European waters ArchiMer
Piet, G; Jansen, H; Rochet, Marie-joelle.
This study describes the process of evaluating potential indicators for an ecosystem approach to fishery management in European waters by evaluating these indicators against existing criteria using questionnaires completed by experts. We (i) compare the use of a longer list of simple criteria with a shorter list of elaborate ones; (ii) compare evaluation results when screening criteria are applied to specific indicators vs. high-level headline indicators; and (iii) examine whether detailed questionnaires, with elaborate indicators and elaborate criteria, result in ranked scores that are less influenced by familiarity with the indicators. The results show that the ranked scores of indicators are affected by the level of detail, both in terms of criteria and...

Evaluation, scénarios et viabilité écologique et économique des pêcheries côtières tropicales : application au cas de la Guyane Française ArchiMer
Cisse, Abdoul.
The need for an integrated approach to fisheries is now widely affirmed, including the FAO, in particular in the context of tropical artisanal fisheries. These small-scale fisheries, often multispecies are very important in terms of production, employment and food security. However these fisheries and the exploited resources are often characterized by a lack of data making difficult their management within an ecosystem approach, and by the ecological and economic system complexities including trophic and technological interactions. This thesis aims to contribute to the development of bioeconomic tools for small tropical fisheries in a sustainable management perspective based on the ecosystem approach. In this perspective, the French Guiana coastal fishery...

Managing Fisheries in the context of an integrated policy: the importance of spatial issues ArchiMer
Petitgas, Pierre; Ernande, Bruno; Andonegi, Eider; Fabi, Gianna; Scarcella, Guiseppe; Kapiris, Kostas; Leocadio, Ana.
A variety of conservation policies now frame the management of fishing activity and so do also the spatial planning of different sectorial activities. These framework policies are additional to classical fishery management. There is a risk that the policies applying on the marine system are not coherent from a fisheries point of view. The spatial management of fishing activity at regional scale has the potential to meet multiple management objectives, on a habitat basis. Here we consider how to integrate multiple objectives of different policies into integrated ocean management scenarios. In the EU, European Directives and the CFP are now implementing the ecosystem approach to the management of human activity at sea. In this context, we further identify...

Promoting Health and Well-Being by Managing for Social–Ecological Resilience: the Potential of Integrating Ecohealth and Water Resources Management Approaches Ecology and Society
Bunch, Martin J; Faculty of Environmental Studies, York University; Network for Ecosystem Sustainability and Health; bunchmj@yorku.ca; Morrison, Karen E; Department of Population Medicine, Ontario Veterinary College, University of Guelph; Network for Ecosystem Sustainability and Health; karenm@uoguelph.ca; Parkes, Margot W; Health Sciences Program, University of Northern British Columbia; Network for Ecosystem Sustainability and Health; mwparkes@interchange.ubc.ca; Venema, Henry D; International Institute for Sustainable Development; Network for Ecosystem Sustainability and Health; hvenema@iisd.ca.
In coupled social–ecological systems, the same driving forces can result in combined social and environmental health inequities, hazards, and impacts. Policies that decrease social inequities and improve social cohesion, however, also have the potential to improve health outcomes and to minimize and offset the drivers of ecosystem change. Actions that address both biophysical and social environments have the potential to create a "double dividend" that improves human health, while also promoting sustainable development. One promising approach to managing the complex, reciprocal interactions among ecosystems, society, and health is the integration of the ecohealth approach (which holds that human health and well-being are both dependent on...

Satellite remote sensing for an ecosystem approach to fisheries management ArchiMer
Chassot, Emmanuel; Bonhommeau, Sylvain; Reygondeau, Gabriel; Nieto, Karen; Polovina, Jeffrey J.; Huret, Martin; Dulvy, Nicholas K.; Demarcq, Herve.
Satellite remote sensing (SRS) of the marine environment has become instrumental in ecology for environmental monitoring and impact assessment, and it is a promising tool for conservation issues. In the context of an ecosystem approach to fisheries management (EAFM), global, daily, systematic, high-resolution images obtained from satellites provide a good data source for incorporating habitat considerations into marine fish population dynamics. An overview of the most common SRS datasets available to fishery scientists and state-of-the-art data-processing methods is presented, focusing on recently developed techniques for detecting mesoscale features such as eddies, fronts, filaments, and river plumes of major importance in productivity enhancement and...

The Mediterranean region is of fundamental importance to Europe given its strategic position. The responsibility for its overall ecosystem integrity is shared by European Union Member States (EU-MS) and other Mediterranean countries. A juxtaposition of overlapping governance instruments occurred recently in the region, with the implementation of both the Marine Strategy Framework Directive (MSFD) for EU-MS and the Ecosystem Approach Strategy (ECAP) for all Mediterranean countries, including EU-MS. Both MSFD and ECAP are structured around vision-driven processes to achieve Good Environmental Status and a Healthy Environment, respectively. These processes have clear ecosystem-based, integrated policy objectives to guarantee the preservation and integrity of...

Sustainability of tropical small-scale fisheries: Integrated assessment in French Guiana ArchiMer
Cisse, Abdoul; Blanchard, Fabian; Guyader, Olivier.
Like many tropical small-scale fisheries, the French Guiana coastal fishery is characterized by the high fish biodiversity of its ecosystem, the weak selectivity of the fleets exploiting the resources, and the heterogeneity of the vessels in terms of size and fishing techniques. The Rapfish method is used to assess sustainability within 11 fishery systems by means of 27 attributes relating to ecological, economic, social, and technological fields. Overall results indicate an average performance in the weak sustainability range. Comparisons made among the FSs show a gradient of sustainability performance from the western portion of the coast to the eastern portion. Several recommendations are formulated to raise the current “sustainability” status, such as...

Our ability to meet environmental targets is often constrained by processes and events that occur over long timescales and which may not be considered during the planning process. We illustrate with examples and define three major types of temporal scale phenomena of relevance to marine managers: Memory and Future Effects (jointly called Legacy Effects) and Committed Behaviors. We examine the role of these effects in achieving marine environmental targets in Europe under the Marine Strategy Framework Directive and the implications for future management, indicating the increased importance that these temporal phenomena give to reducing future pressures.

The Evolution of an Ecosystem Approach: the Diamond Schematic and an Adaptive Methodology for Ecosystem Sustainability and Health Ecology and Society
Waltner-Toews, David; University of Guelph; dwaltner@uoguelph.ca; Kay, James; ;.
Over the past 15 yr, an international network of researchers has developed and tested a methodology for integrating complex systems theories into sustainable development projects. Drawing on our best theoretical understanding of complex systems and combining it with best practices of community engagement drawn from a wide variety of sources, we have developed a methodology that is theoretically sound and practically effective. AMESH, an Adaptive Methodology for Ecosystem Sustainability and Health, has emerged from, and been tested in, Nepal, Kenya, Canada, and Peru.

Towards the implementation of an integrated ecosystem fleet-based management of European fisheries ArchiMer
Gascuel, Didier; Merino, G.; Doering, R.; Druon, Jean-noel; Goti, L.; Guenette, S.; Macher, Claire; Soma, K.; Travers-trolet, Morgane; Mackinson, Steve.
Using the Celtic Sea and the North Sea as case studies, the fleet-based approach is shown to be the pathway to implement an effective ecosystem approach to fisheries management (EAFM) in European seas. First, a diagnostic on the health of each ecosystem is proposed based on the reconstruction of long time-series of catch, the analysis of mean indicators or stocks trajectories derived from ICES stock assessment results, and the analysis of ecosystem indicators. Then, a fleet-based synthesis is presented using indicators of both the ecological impact and the economic performances of the major fleets operating within each ecosystem. In particular, assessment diagrams show whether each fleet segment, on average, sustainably exploits the stocks. Although...
