Challenges and Prospects of Fisheries Co-Management under a Marine Extractive Reserve Framework in Northeastern Brazil

In Brazil, Marine Extractive Reserves—MERs (Reservas Extrativistas Marinhas) represent the most significant government-supported effort to protect the common property resources upon which traditional small-scale fishers depend. From an initial small-scale experience in 1992, MERs have expanded countrywide, now encompassing 30 units (9,700 km²) and nearly 60,000 fishers. Despite such escalating interest in the model, there is little research on the effectiveness of MERs. In this article, we discuss relevant parts of the history and examine the current situation of the fisheries co-management initiative in the Marine Extractive Reserve of Corumbau, which was created in 2000 as the first MER to encompass coral reefs and reef fisheries. We describe the Extractive Reserve co-management arrangement and its main policy and legislative challenges. Finally, we discuss the prospects for the use of MERs as management frameworks for traditional small-scale fisheries in Brazil.     

Ecosystem-Based Fisheries Management in the Chesapeake: Developing Functional Indicators

A step-wise approach to implementing ecosystem-based fishery management (EBFM) offers both a tractable policy opportunity and feasible set of scientific responsibilities in ongoing efforts to incorporate ecosystem dynamics into fisheries management. This case study of oysters in the Chesapeake takes a regional approach and utilizes a fishery species that is a popular menu item, an important habitat for other fish species, and a cultural touchstone in the area. From grounding in ecosystem service policy goals and a survey of stakeholders from across industry, management, science, and community groups, we developed eight indicators that are meant to serve as a first-order check for EBFM. We evaluated these indicators based on data availability, spatial coverage of the whole region, and relevance to ecosystem service goals. Spatial integration of indicators addressing chemical, biological, social, and economic factors, allows identification of localities within the region that require more attention, either by scientists or policymakers, in order to meet EBFM goals.     

Viewpoint: The Social Dimension in Icelandic Fisheries Governance

Fisheries are a complex mixture of social, political, economic, and biological aspects, and often biological or economic end goals are given priority in fisheries governance. However, there is a growing trend around the world to include non-economic social objectives in fisheries management schemes, e.g., supporting rural communities, increasing opportunities for newcomers or part-time fishermen, or providing equitable access for culturally and historically important fisheries. In Iceland, fisheries management has given biological and economic goals' precedence over social goals, and there is no formal inclusion of a social science advisory body or formalized direct input from all relevant stakeholders in the fisheries governance process. Non-economic social sciences such as geography, anthropology, sociology, and political science can add important information and considerations that in turn make fisheries more sustainable in the long run. In this paper, we explain the role of social science in fisheries governance, explore how social aspects are addressed in other fisheries governance schemes, and review highlights from fisheries social science research in Iceland. We hope to generate a meaningful conversation regarding the possibilities of a modern, pioneering fisheries' governance process in Iceland where social, economic, and biological goals and research are all given equal attention.

Lessons from a Multi-Scale Historical Reconstruction of Newfoundland and Labrador Fisheries

In this article we use a multi-scale, multi-method historical reconstruction of post– World War II social-ecological interactions within fisheries in Newfoundland and Labrador to explore the dynamics of intensification, expansion, and resource degradation in managed fisheries. Our case study draws on landings statistics, other archival information, and the Local Ecological Knowledge (LEK) of fish harvesters to explore these linked dynamics at the macro, meso, and micro levels. By some measures we found large scale trends toward intensification of effort leading to over-harvesting at macro (province wide) levels. At the same time, at the local level (micro-scale) and across sectors and regions (the meso-scale), we found highly fluid fishing practices and a complex suite of stated motivations for change. As a basis for effective governance, an understanding of the dynamics of interactive restructuring in social ecological systems will require multi-scale analyses that are sensitive to this complexity.     

Integrated Coastal Management in Philippine Local Governance: Evolution and Benefits

In 1991 the Philippine government shifted many coastal management responsibilities to local governments and fostered increased local participation in the management of coastal resources. In their delivery of integrated coastal management (ICM) as a basic service, many local governments have achieved increasing public awareness of coastal resource management (CRM) issues. Continuing challenges are financial sustainability, inadequate capacities, weak law enforcement, and lack of integrated and collaborative efforts. To address these challenges, a CRM certification system was developed to improve strategies and promote incentives for local governments to support ICM. This system is being applied by an increasing number of local governments to guide the development and implementation of ICM in their jurisdiction. The CRM benchmarks required for a local government to achieve the first level of certification are: budget allocated, CRM related organizations formed and active, CRM plan developed and adopted, shoreline management initiated and two or more best practices implemented. Implementation is providing tangible benefits to communities through enhanced fisheries production associated with MPAs, revenues from user fees and enhanced community pride through learning exchanges and involvement in decisions, among others.     

Catalyzing Coastal Management in Kenya and Zanzibar: Building Capacity and Commitment

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues.     

Estuary Management and Recreational Fishing Benefits

Recognition of the benefits to society supported by estuary ecosystem functions and services, and threats to these benefits posed by human activities, has led to various public programs to restore and protect estuaries at the federal, state, and local levels. As available budgets shrink, program administrators and public elected officials struggle to allocate limited restoration and protection funds to the highest priority areas. Economic benefit and cost information can provide useful inputs into this decision-making process by quantifying estuary restoration and protection benefits and costs in commensurate terms. In this paper, a combined actual and intended travel behavior model is described that can be applied to estimate the recreational fishing benefits of estuary restoration and protection. The model was estimated for recreational fishing in the Lower Atchafalaya River Basin estuary along the Gulf of Mexico, Louisiana, USA coast. Changes in freshwater flows into this estuary may affect redfish and speckled trout game fish populations. The model indicates that changes in catch rates of these two species would have a relatively minor affect on annual fishing trips per angler. However, because total effects may be large when effects per angler are aggregated across total anglers, resource management agencies should consider these changes in recreation benefits when evaluating projects that influence the ecology of coastal estuaries, fish populations, and catch rates. Moreover, in other coastal areas or situations, the responsiveness of angling trips to changes in catch rates may vary because of differences in user populations, environmental conditions, fish populations, and fishing experiences.     

Fisheries Governance Affecting Conservation Outcomes in the United States and European Union

Abstract

Fisheries management in the USA, as governed by the Magnuson–Stevens Fishery Conservation and Management Act (MSA), has been decidedly more successful at meeting its conservation goals than has fisheries management in the EU, as governed by the Common Fisheries Policy (CFP). In an effort to explain the different outcomes in these two systems that share many management attributes, we evaluated them against a list of effective governance attributes gleaned from the literature. We also examined the distribution of rights and responsibilities within each system, and the resulting stewardship incentives. Five effective governance attributes are fully realized under the MSA but have historically been absent from the CFP system: adequate regulatory authority, effective enforcement mechanisms, science-based decision-making, conservation-oriented goals and clear objectives, and directives. These governance system gaps, along with uneven distributions of rights, responsibilities, and incentives, may be responsible for the observed difference in conservation outcomes.     

Application of a Sustainable Fisheries Development Indicator System (SFDIS) for Better Management Outcomes in Taiwan Offshore and Coastal Fishery

A sustainable fisheries development indicator system (SFDIS) is proposed in this article to monitor management of Taiwan's offshore and coastal fisheries. Demonstration of its application shows that the ecological index is tending toward sustainability but to conserve fisheries’ resources it is necessary to strengthen habitat protection and management through a partnership approach. The economic index is tending toward unsustainability as a result of a decline in fisheries’ Gross Domestic Product (GDP), value, economic production, and investment. An aging fisherman population and decreasing social performance and resilience contribute to unsustainability of the social index. By contrast, the institutional index is sustainable because of improved management efficiency, ability, and capacity-building. However, some problems exist with regard to compliance and acceptability of institutional expense. Overall, the SFDIS suggests that an increase in employee number, incorrect statistical data, and unacceptable institutional expense will make Taiwan's offshore and coastal fisheries unsustainable in the long run.     

Decentralized Coastal Zone Management in Malaysia and Indonesia: A Comparative Perspective 1

Transferring decision-making process from central to local government and enhancing the role of local communities in managing coastal zones is an increasing commitment by governments in Southeast Asia. This article analyzes decentralized coastal zone management in two neighboring countries, Malaysia and Indonesia. The Federal system in Malaysia is argued to be able to influence more decentralized coastal zone management and to promote community-based management approaches. Meanwhile, the large diversity of coastal resources and communities combined with a still as yet tested decentralization policy in Indonesia is argued to bring more challenges in implementing the decentralization and community-based approaches in coastal zones. The lessons learned in this study provide insight in how far decentralized coastal zone management has taken place in Malaysia and Indonesia. The significant differences in the pattern of coastal zone management in these two countries are discussed in detail. This study recognizes that co-management and community-based approaches can be appropriate in dealing with coastal zone management. This comparative perspective is important to the development of a bigger picture of sustainable coastal zone management processes and cross-regional knowledge-sharing in Southeast Asia.     

Adaptation Pathways in Coastal Case Studies: Lessons Learned and Future Directions

Climate change adaptation presents a difficult challenge for coastal towns around the world, forcing local governments to plan for sea level rise in a contentious decision-making space. The concept of “adaptation pathways,” a diagnostic and analytical tool to assist in adaptive planning and decision-making, is gaining traction as a way of framing and informing climate adaptation. It provides decisionmakers a way to acknowledge the inter-temporal complexities and uncertainties associated with the novel dynamics of climate change and a mechanism to manage these challenges in the local context. In 2012, the Australian Government funded an 18-month program to provide decisionmakers in the coastal zone an opportunity to test the utility of the adaptation pathways concept for coastal climate adaptation. Using a selection of completed projects as case studies, we performed a document analysis to better understand the learnings from the projects. The main themes surrounded: (1) the utility of the adaptation pathway framework in developing options, (2) decision-making rationale and criteria, and (3) stakeholder participation in pathway development. A project participant survey was developed to further understand these themes. Our analysis reveals that “adaptation pathways” was generally framed narrowly and conservatively to emphasize extant economic, administrative and legal considerations over community, participatory, or exploratory ones. Although some case study projects were able to reach a point in the pathway discussion to actively involve stakeholders in their decision-making process, many case studies continued to build technical data as a method for defending policies and actions. These results indicate that coastal adaptation can take-up adaptation pathways as a useful concept for decision-making and planning; however, many councils may still require assistance in stakeholder communication processes in order to develop sociallyacceptable plans that take into account the full range of values affecting local coastal environments.     

An Overview of Spatial Management and Marine Protected Areas in the East China Sea

Marine ecosystems of the East China Sea are rich in biodiversity, with 12,933 species of which approximately 47.7% are endemic. As anthropogenic impacts are intensifying, fishery resources and biodiversity in the East China Sea are under threat from overfishing, habitat loss, pollution, and biological invasions. Marine protected areas (MPAs) and other spatial management measures are believed useful tools to protect and restore biological resources. Seventeen nature reserves, seven special marine reserves, and three fishery resource conservation zones covering a combined area of 102,156 km² have so far been established in the Chinese East China Sea in order to protect fishery resources, biodiversity, and marine landscapes. This article provides a review and inventory of MPAs in the Chinese East China Sea as implemented by the People's Republic of China.     

Comparing Fisher Interviews,Logbooks, and Catch Landings Estimates of Extraction Rates in a Small-Scale Fishery

Researchers are turning to alternative data sources (e.g., resource user knowledge) to provide information required for wildlife management. Little is known about the reliability of data elicited from resource users relative to data obtained from user-independent approaches (e.g., observations of fish catches). We test for consensus among three methods that quantify past (1996 to 2007) seahorse catch-per-unit-effort (CPUE) for a small-scale, data-poor fishery in the Philippines: interviews with fishers about good, bad, and typical catch; fisher logbooks; and observations of catch landings. Interviews and logbooks indicated no trends in CPUE through time, consistent with results from the fisher-independent metric, catch landings. Although interview estimates of “typical” CPUE greatly exceeded “typical” observed catches and logbook estimates, interview estimates of “bad” CPUE were comparable. Catch landings estimates for a fisher in a particular year were uncorrelated to what he reported during retrospective interviews. Interviews should be used cautiously to inform specific catch targets (e.g., total allowable catches), although including interview questions about a range of catch experiences (e.g., good, bad and typical), may improve interview-derived data. Logbooks are particularly useful for capturing information about fishing expeditions that produce no fish, which are largely missed by other methods.     

Coastal Erosion in Ghana: Causes,Policies, and Management

Coastal erosion is a serious problem that affects the safety and livelihoods of many coastal dwellers along Ghana's coast. Despite the fact that coastal erosion is a natural phenomenon, erosion trends have been largely aggravated by human-induced factors. This study analyzed shoreline change rates for three neighbouring coastal communities in the Central region of Ghana; Elmina, Cape Coast and Moree. Two epochs were analyzed, 1974–2012 (medium-term) and 2005–2012 (short-term), using ArcGIS and Digital Shoreline Analysis System. Overall, the entire study area recorded average shoreline change rates of ?1.24 myear^?1 and ?0.85 myear^?1 in the medium-term and short-term period respectively. Less consolidated shoreline segments recorded higher erosion rates in both periods while cliffs and rocky segments experienced very little erosion or high stability. Because shorelines undergoing chronic erosion do not fully recover after short-term erosion events such as storms, facilities located close to such shorelines are threatened. Taking a proactive approach to coastal erosion management, such as coastal sand mining prevention, inter-sectoral land use management and adopting a construction setback approach may be prudent for the long-term management of the coast since this recognizes future shoreline changes and safeguards coastal landscape for other uses.     

Small-Scale Sicilian Fisheries: Opinions of Artisanal Fishers and Sociocultural Effects in Two MPA Case Studies

Marine resource management and related stakeholder conflicts have been clearly defined in recent decades as pressing issues worldwide. This article provides a comparative study of the management regimes of the Gulf of Castellammare Fishery Reserve and the Egadi Islands Marine Reserve in Sicily, Italy. What managers in these two reserves have neglected to include in management is a social science evaluation scheme to ensure the development of more effective overall management. This is a significant problem in both Italy and the rest of the Mediterranean, where few sociocultural and economic studies have been conducted. Using data collected with standard anthropological field methods, analysis was conducted on how artisanal fishers are impacted by reserves, the extent of their knowledge regarding regulations, their opinions on management, and demographics. The results indicate that while fishers in the two case studies are all aware of the marine reserves where they fish, most fishers are not well informed of the associated regulations. Fishers feel alienated from the management process, and would feel more comfortable with reserve managers and regulations if they were involved in management. The article concludes by showing how such data could help to develop more useful and practical management practices in both these and other MPAs with similar problems.     

Collaborative Integrated Management in Canada's North: The Role of Local and Traditional Knowledge and Community-Based Monitoring

The objective of this article is to take stock of integrated management in the Canadian North, assessing its contribution to the advancement of knowledge and practice regarding the role of indigenous knowledge and community-based monitoring. This is done in three steps. (1) The Beaufort Sea, designated a Large Ocean Management Area under Canada's Oceans Action Plan, is used as an example of a consultative planning process, with special attention to indigenous peoples. (2) How specifically can indigenous knowledge contribute to integrated management? The problem of Arctic marine food web contamination is used to illustrate the strengths and limitations of traditional ecological knowledge and its relationship to science. (3) The discussion of community-based monitoring relies on Voices From The Bay study involving the Inuit and Cree of Hudson and James Bay, and Inuit observations of climate change study in the Canadian western Arctic. The examples together address integrated coastal management and the health of ocean ecosystems, showing how stakeholder participation and knowledge helps widen the range of knowledge to understand and help monitor environmental change.     

CZM in California: Successes and Challenges Ahead

California has a forty-year history of successful coastal zone management. The San Francisco Bay Conservation and Development Commission, the California Coastal Commission, and the State Coastal Conservancy have protected and made accessible hundreds of miles of shoreline. While each agency has played a critical role, this article focuses on the Coastal Commission. Implementing the California Coastal Act, the Coastal Commission has partnered with local government, other agencies, nongovernmental organizations (NGOs), and the public to concentrate new development in already developed areas, and much of the rural coastal zone looks as it did in 1972. The Commission has protected and expanded public shoreline access through its regulatory actions. Using strong ecological science the Commission has protected a wide variety of sensitive habitats and wetlands. And under the authority of the Coastal Zone Management Act, the Commission has reviewed thousands of federal projects to assure that they are consistent with the Coastal Act. Challenges continue, though, including population growth, sea-level rise, and inadequate funding to update local coastal land use plans to address new issues, such as climate change adaptation. New investment is needed at the national, state, and local level to continue the success of the California program.
