This paper examines an approach that integrates the judgment and perceptions of coastal resource users in prioritizing the criteria and indicators for fisheries management impact evaluation. Five criteria with corresponding indicators were identified and selected namely, acceptability, biotic diversity, economic performance, enforceability, and equity. The weights of importance of criteria and indicators were determined through the Analytic Hierarchy Process applied in a case study with 23 resource user groups (categorized as fishers, local government unit, non-government organization, private sector and women) in San Miguel Bay, Philippines.The results of this study revealed that overall, acceptability is the most important criterion in evaluating the impacts of fisheries management strategy in San Miguel Bay, especially for the local government units and fishers groups. The best measure of acceptability criterion are the indicators resource users participation in fisheries management process, level of awareness of resource users in fisheries resource management and number of fishers who belong to an organization. Ten groups have consistency ratios between 0.0 and 0.08 which are within the acceptable level of 0.10. Conversely, most groups (78%) have consistency ratios less than 0.26. Also, the results of the preference analysis are remarkable because among the representative groups, most fishers groups exhibited consistencies in their judgments (average consistency ratios of 0.06-0.08). Economic performance indicators were consistently judged across groups indicating that individuals present higher convergence of views toward economic objective.  相似文献

It was realized that with the increasing rate of deterioration of fisheries resource in the Philippines, there was no way the country could pursue a pathway of sustainable development. After enactment of the Local Government Code of 1991, the government actively promoted community-based fisheries management (CBFM) to conserve the coastal resources. The increased attention paid to community-based fisheries management has come about through experience of the poor performance of other approaches and through the study of traditional systems of community management of natural resources which have not only survived but also appear to perform better than the alternatives. This paper presents the results of a study to assess the impacts of CBFM projects in the Philippines, using meta-analysis, on the equity and sustainability of small-scale coastal fisheries. The outcomes indicate a positive impact of CBFM on the equity of both involvement in management and benefit sharing and sustainable management of fisheries resources through the investigation of effective magnitude (effect size) based on eight indicators. The positive summary effect sizes of participation, influence, control, access, and income conjunctly portrayed an improved equity in the fishing community by implementing CBFM. The positive summary effect sizes of compliance and conflict indicated an affirmative community and, therefore, sustainable fisheries management. While the negative summary effect size of resource revealed the difficulties in recovering fish abundance in a relatively short period of time. Also, ten years of implementation of CBFM was discovered as the minimum duration with perceived equity and sustainability improvement for most indicators.  相似文献

Fourteen indicators of marine living resource management performance by country, reflecting both their intention to sustainably use the resource within their Exclusive Economic Zones and the effectiveness of their policies, were developed and the performances of 53 maritime countries were assessed. Four rankings of the countries, which jointly account for over 95 percent of the world's marine fisheries landings, are presented here as aggregated scores of the fourteen indicators, using different schemes for weighting the indicators, each reflective of the management preferences identified by the Global Environment Outlook 4 (GEO4) future development scenarios: Market First; Policy First; Security First; and Sustainability First. The resulting rankings differed substantially between the weighting schemes for the top performing countries but less so for the countries performing poorly.  相似文献

This paper presents the results of an analysis of resource use conflicts in areas near marine protected areas in Mabini–Tingloy, the Philippines. The author found large differences between groups of stakeholders in terms of perceived benefits and costs of conservation and tourism, and these inequalities have led to conflicts between various stakeholder groups. Marked by unequal power relationships, the conflicts place subsistence fishers as the weakest stakeholders. Fishers also have the lowest rates of knowledge of and participation in conservation activities. The study concludes that in order for conservation programs to be effectively transitioned onto the social and legal fabric of Mabini–Tingloy, resource use conflicts need immediate attention.  相似文献

Conservation success is often predicated on local support for conservation which is strongly influenced by perceptions of the impacts that are experienced by local communities and opinions of management and governance. Marine protected areas (MPAs) are effective conservation and fisheries management tools that can also have a broad array of positive and negative social, economic, cultural, and political impacts on local communities. Drawing on results from a mixed-methods study of communities on the Andaman Coast of Thailand, this paper explores perceptions of MPA impacts on community livelihood resources (assets) and outcomes as well as MPA governance and management. The area includes 17 National Marine Parks (NMPs) that are situated near rural communities that are highly dependent on coastal resources. Interview participants perceived NMPs to have limited to negative impacts on fisheries and agricultural livelihoods and negligible benefits for tourism livelihoods. Perceived impacts on livelihoods were felt to result from NMPs undermining access to or lacking support for development of cultural, social, political, financial, natural, human, physical, and political capital assets. Conflicting views emerged on whether NMPs resulted in negative or positive marine or terrestrial conservation outcomes. Perceptions of NMP governance and management processes were generally negative. These results point to some necessary policy improvements and actions to ameliorate: the relationship between the NMP and communities, NMP management and governance processes, and socio-economic and conservation outcomes.  相似文献

Many conservationists and local governments in the Philippines (and other tropical countries) have attempted to link marine protected areas (MPAs) with dive tourism, arguing that the user fees generated by dive tourism can potentially generate satisfactory outcomes for all stakeholders. In this paper, an account of the relationship between MPAs, dive tourism and small-scale fisheries in the Calamianes Islands, Philippines, is presented. It is argued that although the assumed harmonious relationship between marine conservation and dive tourism may work in theory, in practice different understandings of MPAs can create conflict.  相似文献

A review of indicators for an ecosystem approach to fisheries management is presented, focusing on multispecies fisheries and limited resources for assessments and implementation, as often is the case in developing countries. Emphasizing the need to link indicators to management objectives, indicators from the literature are grouped into four categories, relating to the immediate fisheries resource base (single-species and multispecies indicators) and the wider ecosystem (habitat structure and ecosystem functioning). The usefulness of these indicators is assessed along three dimensions of acceptability among stakeholders, observability, and relation to fisheries management using a traffic light approach. The top ranking indicators are highlighted as a generally good start for any particular fishery management case. It is, however, argued that, even with similar management objectives, indicators need to be specific to both ecosystems and the institutional set-up if they are to be effective for management, and that indicators may consequently differ considerably between individual management applications.  相似文献

Managing small-scale fisheries in a developing country like the Philippines is very challenging because of high pressures from expanding fishing population, poverty and lack of alternative options. Thus, resource-focused fisheries management initiatives such as marine protected area (MPA) establishment will likely result in further marginalization of the poor fishers which could pose more serious problems in coastal communities. In this study, the status of small-scale fisheries in 44 coastal towns in the Philippines was assessed using FISHDA (Fishing Industries' Support in Handling Decisions Application), a simple decision support tool which requires minimal or easily-generated data. Results showed that 68% (30 out of 44) of the studied towns have unsustainable fisheries unless 58% of their fishing grounds are protected from all fishing activities. Alternatively, 53% of the active fishers in towns with unsustainable fisheries must totally stop fishing to avert fishery collapse. Alarming as it may sound, this is still an underestimate as catches incurred by the highly efficient and destructive illegal fishing activities such as blast, poison and large-scale fishing, which are reported to be still rampant in many coastal areas in the Philippines, were not accounted for in this study. This study demonstrated that MPAs alone may not be enough to avert fishery collapse even if MPA size is increased from the current 3% to 15% of the municipal waters, i.e. up to 15 km from the shore, as required by the Philippine law. Various challenges confronting the fishery and important recommendations to address them are further discussed.  相似文献

Mitigating the environmental impact of commercial fishing, by avoiding, minimizing and compensating for adverse effects, is core business for fisheries management authorities globally. The complex interplay of ecological, economic, and social considerations has often resulted in bycatch management being reactive, confrontational and costly. In many cases it has been difficult to demonstrate success and to establish whether bycatch management has been efficient or effective. This article proposes standards for bycatch management following reviews of literature, international agreements and Australian domestic fishery management policies, and consideration by many technical experts and several stakeholder representatives. The standards have been developed using Australian Commonwealth fisheries – and the international fisheries agreements to which Australia is party – as a baseline, but should be applicable to both domestic and regional/international governance systems. The proposed standards involve quantifying fisheries bycatch, agreeing on operational objectives, assessing the effects of fishing on bycatch populations, establishing the cost-effectiveness of mitigation measures, and evaluating performance. The standards encourage domestic management measures that are consistent with the guidance and requirements of international agreements and regional fisheries management organisations. The importance of engaging stakeholders throughout the process is recognised. The standards provide a framework for measuring performance and a checklist of actions for managing bycatch at a fishery level. They have the potential to facilitate the development of more strategic and effective approaches to bycatch management, with defined goals, monitoring systems, and adaptive decision-making. This review of past bycatch management, including the application of the proposed standards to the mitigation of shark bycatch in an Australian longline fishery, demonstrates that the proposed standards are operationally feasible but that they have not always been applied. Specifically, monitoring the performance of bycatch management measures has not always followed their implementation.  相似文献

Management interventions to reduce pressures on coral reefs often include attracting fishers to non-extractive non-fishery supplemental livelihoods. We look at the case of coral reefs in Lingayen Gulf, Philippines to understand the impacts of local (i.e., aquaculture and tourism), regional, and national development on the artisanal fisheries sector. Using household surveys and a coral reef interaction index (CRII), we obtained relative levels of dependency and impacts of fisheries, aquaculture, and tourism on coral reefs for livelihood. Results show that overall dependency on coral reefs remains high despite its decreasing quality. Socio-economic profiles reveal steep hurdles in shifting fishers to aquaculture. Both aquaculture and fisheries will continue to grow and eventually compete for space if left unmanaged further resulting in reduced reef quality. Shifts of fishers to tourism-based and other low-capital requirement mariculture (e.g., sea ranching) are more realistic than the expectation of absorbing fishers into current aquaculture businesses. Strengthening local coastal governance capacity to improve proactive responses for micro–macro development interactive synergy will also help reduce the impacts of development on reefs. Improving safety nets for coastal communities through skills enhancement and supplemental livelihood options that facilitate stewardship and reef recovery is an imperative. Transforming the lessons learned at village level actions to sustain municipal scale programs and institutional cooperation among stakeholders such as through marine protected area networks remain a challenge. Sharing forums and joint financing of coastal resource management remain to be realized through public and private partnerships and expansion of development for investments in social enterprises.  相似文献

This study examines the key characteristics of successful fisheries learning exchanges (FLEs). FLEs are peer-to-peer gatherings in which fishery stakeholders from different communities freely exchange information and experiences surrounding fisheries challenges and solutions. They are usually organized by fishers, non-governmental organizations and governments and are credited as an integral tool for the diffusion and adoption of fisheries management strategies. Despite their numerous perceived benefits within fisheries conservation and management, little research has been conducted on FLEs. This multiple case study addressed the research question: “What are the key characteristics of successful FLEs?” Success metrics were defined during a workshop on FLEs in 2013. For this study, the authors selected six successful FLEs that were presented during the workshop. Documentation of FLEs and key informant interviews with participants and organizers were used as data. The following key elements of successful FLEs emerged from analyses: (1) a clear guiding purpose and flexible objectives, (2) careful and considered selection of participants with diverse professions and conservation beliefs, (3) a mix of activities including giving presentations, conducting site visits, talking with local fishers, spending time on boats or in the water, and participating in cultural activities, and (4) logistical and financial follow-up support, including information dissemination about what participants learned at the FLE. Based on these results, the authors provide recommendations for conducting successful FLEs.  相似文献

The economic value of marine fisheries can be measured by the resource rent that may potentially be earned, which represents a flow of real wealth for the community at large. For the island state of the Maldives we estimate that the resource rent that could be generated by the marine fisheries is in the order of $50 million per annum, constituting some 27% of the current value of landings. This rent is lost due to the de facto open-access nature of fishing. A wealth-based approach to fisheries management would seek to capture the rent, and the paper discusses the constraints and trade-offs that would be faced in applying this in the Maldivian context. We argue that such an approach is entirely consistent with the aim of the 7th National Development Plan which rightly emphasises the need to ensure the sustainability of marine resources for present and future generations.  相似文献

To sustain fishery development and ensure the supply of fish, the role that a sustainable development indicator system plays in the evaluation of fishery management performance is becoming increasingly important. A sustainable indicator system based on the Pressure–State–Response (PSR) framework was developed for local fisheries in Gungliau, Taiwan, between 1995 and 2003. Factor analysis and canonical correlation analysis were also applied to aggregate indicators and analyse the linkage of indicators. The most serious problem facing fishery system in Gungliau is conflicting local and higher levels of enforcement that result in the problems of effort, harvest and fleet age composition related to the pressure component. Fishery resources and the state of ecosystem were also affected by marine environmental change, especially by El Ñino. Consequently, fishermen adjusted their effort and investment to the variation of Fishery resources, leading Gungliau fisheries to unsustainability.  相似文献

This study establishes an offshore and coastal fisheries policy indicator system to evaluate the performance of policies to achieve sustainable development in offshore and coastal fisheries. A modified Delphi method is used to establish this system, and the weights of indicators are calculated using the analytic hierarchy process (AHP) to aggregate indicators. Results show that ecological policies have not achieved their goals because production and catch per unit effort are decreasing. Indicators with respect to management efficiency have increased after the implementation of the buyback and off-fishing programs. However, net returns indicator, which is affected by increasing cost and production value, is stable. Due to inefficient management resulting from insufficient resources, indicators for the number of illegal fishing cases per year and the number of smuggled aquatic production incidents have increased. This shows that requirement for enhanced compliance is necessary. The objective for cultivating talents in fisheries has not been achieved because average wage for fishers is lower than the average civil wage, resulting in an increase in the hiring of foreign fishers.  相似文献

There has been a gradual evolution in fisheries management over the past decades from a focus on sustainability of a single species or stock and resources to a focus on marine ecosystems. Among the issues to be addressed for effective implementation of ecosystem based fisheries management (EBFM) are the appropriate governance arrangements and scale for management. The purpose of this paper is to examine these issues of governance and scale as related to EBFM in tropical developing countries through an analysis of approaches being taken in the Philippines to manage fisheries on a multi-jurisdictional level. The management of fisheries and coastal resources in a number of bays and gulfs, which represent marine ecosystems, is presented. The opportunities and constraints to ecosystem based fisheries management in the Philippines are discussed and lessons for broader application of these governance structures in tropical developing country marine ecosystems are presented.  相似文献

As a commercially important fisheries resource in East Asia, the Chinese surf clam Mactra chinensis has experienced severe population declines in the past decades, probably due to over‐exploitation. To provide scientific bases for fisheries management and artificial breeding, we investigated genetic variation and population structure of Mactra chinensis in Northern China using microsatellites. Samples collected from eight localities throughout natural habitats of the species in Northern China were genotyped. Nine microsatellites revealed high allelic diversity with 14–36 alleles per locus. Observed and expected heterozygosity varied from 0.593 to 0.945 and from 0.638 to 0.958, respectively. Pairwise FST values indicated that all population pairs had small but significant genetic differentiation. A Mantel test showed statistically significant correlations between genetic distance and geographical distance, indicating that genetic differentiation of the Chinese surf clam conformed to a pattern of isolation‐by‐distance. Cluster analysis using neighbor‐joining separated the eight populations into three groups. The three areas of low gene flow identified by barrier analysis corresponded with local oceanographic features, suggesting that marine currents and peninsulas play an important role in population structuring of this species.  相似文献

The effectiveness of coastal management in developing countries is widely perceived to be inhibited by a lack of scientific data on the coastal zone. To try to fill this need for information, donors and big international non-governmental organizations are increasingly initiating large-scale, science-driven conservation programs, with the goal of creating and using management relevant transdisciplinary datasets. In Oceania, these programs are entering a context where local ecological knowledge is already informing existing community-based approaches to coastal management. This paper examines two large-scale programs in Fiji, the Marine Management Area Science initiative and the Vatu-i-Ra and Cakau Levu Reefs Seascape Project, and offers insight relevant to the planning and implementation of similar programs where local management systems are already in place. Research methods used to examine the programs included document analysis, direct observation, and semi-structured interviews with key stakeholders over multiple field visits to Fiji in 2009 and 2010. Results suggest that as donors, non-governmental organizations, and partners move forward in implementing these programs, there must be active steps taken to bridge boundaries between disciplines and among knowledge systems, evaluate the added value of science for all stakeholder groups, and build opportunities for datasets to be used after donor funding ends.  相似文献

In the North-east Atlantic Ocean there are 550 inshore and offshore MPAs established to accomplish a high diversity of objectives, which can be classified into 24 different types of MPA designations. Only 153 of these MPAs have a management plan (MgP) --the basic tool required for an effective management. Amongst these, only 66 are actually managed, i.e. they have the staff and resources required to operate the plan. A common characteristic of these MPAs is the lack of standardized indicators of their performance. In order to address this issue, an alternative approach was developed based on the assessment of management performance using the expert knowledge and perceptions of managers operating MPAs, a universal source of information that could allow overcoming the usual gaps due to the restrictions in coverage of scientific monitoring and assessments. MgPs showed differences among countries but were homogeneous within each country, reflecting the usual top-down approach in the establishment of MPAs. Compliance with the qualitative objectives present in MgPs was higher than compliance with quantitative ones (87% versus 50%), and the MPAs that most successfully achieved their objectives were those with regular monitoring. This analysis also shows that beyond these objectives, the establishment of an MPA and the activities developed as a consequence of its creation have a positive socio-economic impact on the local human community.  相似文献
