Structuring decision-making for ecosystem-based management

Ecosystem-based management (EBM) has been widely accepted as the new paradigm to manage marine ecosystems. Although various efforts have been made to define key components, guidelines, and principles, in support of its implementation, there is still a gap between theory and practice. To implement EBM, managers require a decision-making framework in which the values of constituents, objectives and performance measures are consistent and used to evaluate and choose between alternatives. Structured decision-making (SDM) is a systematic approach that can contribute to develop this framework for EBM. SDM was used for the on-going EBM process on the west coast of Vancouver Island, British Columbia, Canada. This case study provides insights into how SDM can be implemented for EBM, as well as some challenges and opportunities encountered during the process.     

Ecosystem management bioindicators: the ECOMAN project – a multi-biomarker approach to ecosystem management

The ECOMAN project was initiated from an awareness of the complexity of the functioning of coastal marine systems and the clear need for more pragmatic environmental assessment techniques linking environmental degradation with its causes. The aim of the project is to develop a suite of easy to use, cost effective and environmentally valid biological responses (biomarkers) to assess the general health of coastal systems, including estuaries. To achieve this aim, various sublethal endpoints are being measured and evaluated from a range of common coastal organisms showing different feeding types (filter feeding, grazing and predation) and habitat requirements (estuary and rocky shore) and at different levels of biological response (cellular, physiological and behavioural). This holistic integrated approach is essential to identify the full impact of chemical contamination on organisms, and enables the sensitivity of organisms to be ranked and key sentinel species for specific habitats to be identified.     

Participation and fisheries management in Costa Rica: From theory to practice

Participatory fisheries management has been increasingly proposed as a useful management approach to address fisheries problems. However, the criteria regarding its applicability and measures of success still seem unclear. This study reviews the main concepts and theory behind two participatory resource-management approaches and compares them to the reality of fisheries management in Costa Rica. The analysis shows that while the implementation of a participatory approach in fisheries management should be encouraged, it is essential to keep in mind the possible limitations these approaches have. Furthermore, it seems important to improve institutional coordination and develop social, legal and economic policies that will allow the state, together with coastal communities, to contribute in an effective way to fisheries management.     

Swedish coastal fisheries—From conflict mitigation to participatory management

Several research projects have studied Swedish coastal fishery to investigate the conflict between seals and fishery. In recent years, a strategy of participation by means of co-management has been unfolding. Realising that maintaining the coastal fishery requires societal support and knowledge integration, attempts have been made to introduce the principle of participatory management into the centralised Swedish fisheries management system. However, this co-management approach, presently implemented in six pilot projects, will take a long time to develop through a sustained process of experimentation and improvement.

Development and management of a coastal litter campaign: The voluntary coastal partnership approach

The Forth Estuary Forum's Coastal Litter Campaign aimed to develop and implement a community involvement and public awareness-raising programme intended to tackle and monitor the issue of marine litter in the Firth of Forth, Scotland. Beach cleans are an excellent public participation exercise, focusing the public's attention on the issue of marine litter and creating a sense of environmental responsibility. Raising public awareness is the only guaranteed way of reducing marine litter. A combination of education, provision of adequate waste reception facilities and enforcement of legislation is needed to tackle beach litter.     

An ecosystem-based framework for governance and management of maritime cultural heritage in the USA

A new federal administration, alongside initiatives proposed by the President's US Commission on Ocean Policy, provides a timely and critical opportunity for maritime archaeologists and cultural resource managers to re-consider management frameworks for maritime cultural heritage in the USA. Policy is urgently needed that defines governments’ roles and responsibilities in protecting and managing maritime cultural heritage in federal waters. Implementation of a regional governance structure based on the tenets of ecosystem-based management is proposed in this paper to manage and develop these resources effectively. Through regional governance, the maritime heritage of the USA can be conserved for future generations, keeping its citizens connected to deep-rooted maritime traditions and contribute to the well-being, economic growth and development of coastal communities.     

Can co-management emerge spontaneously? Collaborative management in Sri Lankan shrimp aquaculture

Shrimp aquaculture in northwestern Sri Lanka shows co-management like features. To understand the reasons behind co-management and to identify the mechanisms by which co-management is carried out, the paper examines shrimp aquaculture operations in three coastal communities using a case study approach. Water from an interconnected lagoon system is the key input for shrimp ponds, but it is also the potential source of shrimp disease outbreaks that threaten all shrimp farms. Farmers try to prevent the spread of disease by co-operating to adjust the timing of water intake and wastewater release. This is done through a zonal crop calendar system which is developed and implemented by a vertically integrated institutional structure with three levels: sub-zonal/community, zonal, and national. Partnerships, overall sharing of power and authority, and learning-by-doing are key features of this collaborative management system. The case shows that adaptive co-management can develop through collaborative problem-solving over time, even in the absence of legal arrangements.     

Engaging the public in climate change-related pro-environmental behaviors to protect coral reefs: The role of public trust in the management agency

The purpose of this study was to investigate the role that stakeholder trust in a management agency, as a source of information about climate change, plays in relationships among antecedents to climate change-related pro-environmental behavior. Data collected from a survey of Australian residents living adjacent to the Great Barrier Reef Marine Park revealed that lower intensities of institutional trust were associated with a less biocentric worldview, a lower reported awareness of consequences of the impacts of climate change, and a lower sense of obligation to adopt pro-environmental behaviors. Findings suggest that managers should attempt to foster the trust their stakeholders have in their agency because when trust increases, stakeholders develop stronger relationships among the antecedents of pro-environmental behavior.

Making modelling count - increasing the contribution of shelf-seas community and ecosystem models to policy development and management

Marine legislation is becoming more complex and marine ecosystem-based management is specified in national and regional legislative frameworks. Shelf-seas community and ecosystem models (hereafter termed ecosystem models) are central to the delivery of ecosystem-based management, but there is limited uptake and use of model products by decision makers in Europe and the UK in comparison with other countries. In this study, the challenges to the uptake and use of ecosystem models in support of marine environmental management are assessed using the UK capability as an example. The UK has a broad capability in marine ecosystem modelling, with at least 14 different models that support management, but few examples exist of ecosystem modelling that underpin policy or management decisions. To improve understanding of policy and management issues that can be addressed using ecosystem models, a workshop was convened that brought together advisors, assessors, biologists, social scientists, economists, modellers, statisticians, policy makers, and funders. Some policy requirements were identified that can be addressed without further model development including: attribution of environmental change to underlying drivers, integration of models and observations to develop more efficient monitoring programmes, assessment of indicator performance for different management goals, and the costs and benefit of legislation. Multi-model ensembles are being developed in cases where many models exist, but model structures are very diverse making a standardised approach of combining outputs a significant challenge, and there is a need for new methodologies for describing, analysing, and visualising uncertainties. A stronger link to social and economic systems is needed to increase the range of policy-related questions that can be addressed. It is also important to improve communication between policy and modelling communities so that there is a shared understanding of the strengths and limitations of ecosystem models.     

Correct application of the IUCN protected area management categories to the CCAMLR Convention Area

The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) has been working to develop and implement a system of marine protected areas (MPAs) for over 10 years. Within CCAMLR there is a long-held belief that the area covered by the CCAMLR Convention is equivalent to a category IV protected area as defined by the International Union for Conservation of Nature (IUCN). This belief was founded upon a comparison of the central objective of CCAMLR as defined by the CCAMLR Convention with the IUCN definition of a category IV MPA. This advice was accepted by the CCAMLR Scientific Committee but to date there has not been any analysis of this advice within CCAMLR, IUCN or in the literature. This paper critically analyses that advice, and finds that the CCAMLR Convention area does not meet the IUCN definition of an MPA and thus the CCAMLR Convention Area cannot be considered equivalent to a category IV MPA.     

Key principles of marine ecosystem-based management

Ecosystem-Based Management (EBM) has gained international popularity in recent years, but the lack of consensus on its definition has precluded the use of a universal implementation framework. The large number and variety of principles that make up EBM, and the diversity in perspectives among key management players, has impeded the practical application of EBM. Agreement on a list of the essential ingredients of EBM is vital to successful application. A frequency analysis of EBM principles was conducted to identify the Key Principles that currently define EBM, from a list of twenty-six principles extracted from a subset of the EBM theoretical/conceptual literature (covering a range of published sources across disciplines and application types). Fifteen Key Principles were identified (in descending frequency of appearance in the literature): Consider Ecosystem Connections, Appropriate Spatial & Temporal Scales, Adaptive Management, Use of Scientific Knowledge, Integrated Management, Stakeholder Involvement, Account for Dynamic Nature of Ecosystems, Ecological Integrity & Biodiversity, Sustainability, Recognise Coupled Social-Ecological Systems, Decisions reflect Societal Choice, Distinct Boundaries, Interdisciplinarity, Appropriate Monitoring, and Acknowledge Uncertainty. This paper also examines the development of EBM principles over time, leading to predictions on the directions EBM will take in the future. The frequency analysis methodology used here can be replicated to update the Key Principles of EBM in the future. Indeed, further research on potential emerging Key Principles such as ‘Consider Cumulative Impacts’, ‘Apply the Precautionary Approach’ and ‘Explicitly Acknowledge Trade Offs’ will help shape EBM and its successful application in the management of marine activities.     

Angling management organizations: integrating the recreational sector into fishery management

This paper examines ways to reduce conflicts and improve the sustainability and value of marine recreational fisheries by fully integrating the recreational sector into the management of fisheries. One possibility involves a novel approach, here called angling management organizations (AMOs), which combines three of the more pervasive and promising trends in fishery management worldwide—management devolution, strengthened harvest rights, and co-management. AMOs are community-based organizations that are designed to conform to seven basic principles of integrated fishery management, which are described below. AMOs are loosely related to rights-based producer organizations in commercial fisheries, and are expected to strengthen resource stewardship, reduce enforcement and monitoring costs, alleviate management conflicts, and produce greater long-term net economic benefits in recreational fisheries. The other organizational structures considered here, including the management status quo, do not conform to all seven principles and are not expected to be as effective as AMOs.

Considering ecosystem-based fisheries management in the California Current

Recognizing that all management decisions have impacts on the ecosystem being exploited, an ecosystem-based approach to management seeks to better inform these decisions with knowledge of ecosystem structure, processes and functions. For marine fisheries in the California Current, along the West Coast of North America, such an approach must take into greater consideration the constantly changing climate-driven physical and biological interactions in the ecosystem, the trophic relationships between fished and unfished elements of the food web, the adaptation potential of life history diversity, and the role of humans as both predators and competitors. This paper reviews fisheries-based ecosystem tools, insights, and management concepts, and presents a transitional means of implementing an ecosystem-based approach to managing US fisheries in the California Current based on current scientific knowledge and interpretation of existing law.

The way forward with ecosystem-based management in tropical contexts: Reconciling with existing management systems

This paper discusses some of the challenges and opportunities that can arise when implementing ecosystem-based management (EBM) in tropical nations. EBM creates a new series of challenges, problems, and opportunities that must be considered in light of existing governance and management frameworks in a local context. The paper presents five case studies from different parts of the tropical world, including Oceania, insular and continental Southeast Asia, East Africa, and the Caribbean, which illustrate that the implementation of EBM in watershed and marine ecosystems offers a new series of challenges and opportunities for its inclusion with existing forms of environmental governance and management. The paper suggests that EBM is best thought of as an expansion of customary management (CM) and integrated coastal management (ICM), rather than a paradigm shift, and that it has certain benefits that are worth integrating into existing systems when possible. The paper concludes that the cultural and institutional context of CM as well as the experience, technical skills, and legal basis that serve ICM programs are logical platforms from which to build EBM programs. Some guidelines for creating hybrid management regimes are suggested. In sum, declining marine species and ecosystems require urgent action, necessitating utilization of existing paradigms such as ICM and CM as a foundation for building EBM.     

Participatory research supporting community-based fishery management

This paper reports on a project to engage researchers and fishers together in adapting social science approaches to the purposes and the constraints of community-based fisher organizations. The work was carried out in the Scotia–Fundy Region of Atlantic Canada (the Bay of Fundy and Scotian Shelf). Its rationale reflects arguments that (1) effective community-based management requires that managers are able to pose and address social science questions, (2) participatory research, involving true cooperation in all stages, can support this process, and (3) there is a need to overcome practical and methodological barriers faced in developing participatory research protocols, to serve the needs of community-based management while not demanding excessive transaction costs. In this paper, we report on work with fisher organizations, both aboriginal and non-aboriginal, in which social science priorities were set by each organization, and small-scale research projects designed and carried out to meet these needs. This work identified interests among fishers in research on three different levels of meaning: (1) practical livelihood concerns, including what, when and where to fish, and with what intensity of effort, (2) social, economic and political issues (e.g., on institutional structures, politics of access and allocation, overlap and conflict between regulatory regimes), and (3) values and ethics that implicitly or explicitly guide policy development and implementation. Several research themes proved crucial, including those of power sharing, defining boundaries of a community-based group, access and equity, designing effective management plans, enforcement, and scaling up for effective regional and ecosystem-wide management. The research results demonstrate the effectiveness of extending participatory methods to challenge traditional scientific notions of the research process.
