Small-scale fisheries in coral reef areas support the livelihoods of millions of people worldwide. Anthropogenic impacts such as overfishing and climate change increasingly threaten both the reef ecosystem and the livelihood security of the people that depend on the reefs. Adaptive management strategies are needed to adequately deal with these threats, but they require an understanding of the underlying drivers, which often originate and act on multiple levels. Using a social-ecological system approach, the coral reef fishery of the Spermonde Archipelago in South Sulawesi/Indonesia is assessed to identify key drivers and strategic leverage points for management. Under the influence of international markets and technological changes, several export-oriented fisheries have developed in the area that led to distinct subsequent peaks in fishing activity in a pattern of sequential marine resource exploitation. In response to stressors such as seasonality and overfishing of individual locations or species, a number of coping strategies have developed locally. These include extensive borrowing from fishing patrons, diversification of fishing methods, fishing migrations, and the crafting of local institutions to regulate fishing activity. However, the coping strategies hinder, and even decrease, the capacity of the system to adapt to future stressors and undermine the sustainability of the fishery. Potential strategies that target different levels of the fishery system in order to strengthen adaptive management are identified.  相似文献

A regional experiment in co-management is underway in the Lower Amazon that is developing the basic policy and institutional elements for an ecosystem-based approach to floodplain management. This initiative grew out of the grassroots movement of floodplain communities who, concerned with excessive commercial fishing pressure on local fisheries, took control of local lakes and implemented collective agreements regulating fishing activity. This paper describes the main elements of the evolving regional management system. This process has focused on four main dimensions of floodplain settlement and resource use: development of sustainable management systems for floodplain resources, policies and institutions for fisheries co-management, collective agreements for grazing cattle on floodplain grasslands, and a land tenure policy consistent with the objectives of the evolving co-management system. Over the last year INCRA, the National Institute for Colonization and Agrarian Reform, has begun implementation of a comprehensive new land tenure policy that could resolve structural deficiencies in the existing co-management system and provide the basis for the ecosystem-based management of the Lower Amazon floodplain. Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue.  相似文献

ABSTRACT

The evolution of Chinese environmental policy and politics can be better understood in the broader context of institutional changes that have taken place since the late 1970s. In this study, an analytical framework was established to analyze how overall institutional changes were reflected in the roles of relationships between governmental and non-governmental actors engaged in environmental governance. Institutional changes were observed at three levels: informal institutions (cultural traditions, and political ideology); formal institutions (the polity, political system, property rights, and judiciary); and governing mechanisms (structures, regulatory approaches, and incentives). This analysis of interactions between institutional changes and the changing environmental process explained not only the drives and constraints behind China’s environmental policy evolution so far but also shed light on future challenges and opportunities.  相似文献

Humans utilize natural resources for their livelihood and form institutions that are meant to manage the resources. However, many institutions tend to mismanage the natural resources and fail to solve the natural resources crisis because mismatches occur between the institutions and the systems to be governed. Although mismatch problems on temporal, spatial and functional scales are recognized in many natural resources management cases, a need remains to understand how mismatch problems emerge in complex humans in nature systems. This study used social–ecological system (SES) as a framework for conducting a cross-scale assessment of multi-level linked systems for better understanding of mismatch problems. Both bottom-up and top-down institutions regulating the utilization of marine natural resources were examined to unveil the cause of temporal, spatial and functional mismatch problems in Penghu Archipelago, a regional SES in Taiwan. Results of the assessment indicated that the single-level design of conventional institutions in marine natural resources management was a primary cause of mismatch problems. Thus, for better governance, adaptive and cooperative management systems of the marine natural resources in Penghu Archipelago, a more integrated institutional design is recommended.  相似文献

The fundamental point of this paper is that constructs such as system identity stability and changes (tips, transitions, transformations from one identity to another), are subjectively perceived, and acted upon by the social actors that occupy these systems. However, social-ecological systems (SES) research has not yet adequately engaged this subjectivity. I argue, here, that this relative lack of recognition of subjectivity has become a “rigidity trap” for SES scholars. Subjectivity is messy and difficult, and does not fit particularly well within the systems perspectives that characterize resilience work. As such, this lack of engagement has led to self-reinforcing perspectives that emphasize some elements and de-emphasize others, creating a systematic neglect of some principles that might productively challenge existing notions and expand our thinking. Sense of place theory, which emphasizes the creation of meaning as systematically distributed throughout society, is offered as a mechanism for helping SES researchers more fully engage subjectivity.  相似文献

The subtropical coastal zone of Paraná state in southern Brazil is only 80 km long yet environmentally diverse, with relatively pristine coastal landscapes and high marine and coastal biodiversity supporting important artisanal fishing grounds. However, this region began to change in the early 1970s. The development of industrial harbors, as well as unregulated tourism and urban settlement and pollution caused the loss of natural habitats. In addition, commercial shrimp trawlers began to operate in the adjacent shallow shelf areas. Biodiversity was seriously affected, and local fish stocks have decreased drastically in the last four decades. This article describes a long-term program to protect coastal habitats, recover marine biodiversity and diversify the economic base of fishing communities in order to guarantee fish stocks for future generations, hence preserving the social and cultural identities of these communities. Although it is difficult to change traditional fishing practices, fishing communities may exploit alternate components of the marine biological resources in order to achieve environmental, social and cultural sustainability in the long term.  相似文献

This study proposes and empirically tests a framework that integrates the concepts of community resilience and social–ecological system (SES) resilience through community forestry case studies. The framework provides a possible approach for assessing community resilience based on the development and allocation of socio-cultural, economic, and natural capital of individual households within a given forest community. Furthermore, aspects of SES resilience and system dynamics are used to define the potential state thresholds of community resilience. This exploratory attempt to quantify community resilience, using the proposed framework, aims to advance understanding of the conceptual overlaps of SES and community resilience as applied to forestry management. We consider community forestry groups as SES examples in which the community is an important stakeholder in managing natural forest capital. We selected pioneer communities under the community-based forest management (CBFM) Program in the Philippines as our case studies. We found that, on average, CBFM group members demonstrated moderate levels of resilience according to their acquired levels of capital. Although economic capital remained the weakest capital, the CBFM program had a positive effect in increasing the socio-cultural and natural capital of an entire community.  相似文献

New institutional economists have argued that there are many categories of institutions, including market and non-market institutions, which may prove economically efficient, specifically for public goods and common pool goods. The Government of India introduced a non-market community-based institution, known as Joint Forest Management (JFM), for forest management and protection in 1990. JFM is a sharing mechanism for forest planning and management based on sharing of rights and duties, control and decision-making authority over forestlands, between forest departments and local user groups. By 2001, 42 000 Village Forest Committees established under JFM were managing over 11.5 million ha forestland. These institutions have proved very useful, and have contributed to forest management as well as four aspects of sustainable human development (SHD) – ecological output, income generation, village infrastructure development, and community empowerment. In the long-term, community-based institutions will prove to be a foundation of SHD and participatory democracy.  相似文献

Approaches towards the management of artisanal fisheries have been enlightening the scientific literature for approximately the last 20 years. Coming from diverse disciplines such as anthropology, biology, economy, and ecology (especially human ecology), these approaches have dealt with common theory, strategies for cooperation, decision-making models, cultural contexts, and local knowledge. Fishery management depends on an understanding of the interactions between humans and aquatic resources, and in case of indigenous or of native populations, forestry resources are also considered for livelihoods. Acquiring an understanding of the local knowledge about fish and other resources, of collective local arrangements and institutions, of market interactions, and of the decision-making processes of fishers is fundamental for the management of artisanal fisheries. This review includes historical and current approaches associated with the management of artisanal fisheries. These approaches include the following: (a) cultural and human ecological approaches, including ecological models such as optimal foraging theory; (b) institutional approaches, including processes of cooperation associated with local knowledge and institutions; and (c) current ecological-economic propositions towards fishery management, such as payments for environmental services. This revision is illustrated through examples, in particular, of data collected among coastal artisanal fisheries of the SE Atlantic Forest in Brazil.  相似文献

The urgency of managing marine resources is based on the fact that half of the world stocks are fully exploited, excluding those stocks that are already depleted. Artisanal fisheries in Brazil, both inland and coastal, are responsible for about half of the country’s catches. Therefore, management of local artisanal fisheries is a necessity that provides an additional benefit, considering the observation that decentralization and the use of local ecological knowledge (LEK) in management have given better results than centralized, top-down management. In this study, a third system of knowledge–based on practice and training–is built from the local and scientific systems of knowledge, and a method to accomplish practical steps in local management is shown. Four elements are considered for the process of linking systems towards management: (1) an understanding of the natural environment of the fishery and on the use of natural resources by locals; (2) the knowledge of the marine area used by fishers, i.e., location of fishing spots for each species; (3) the understanding of fisher behavior, e.g., using tools from optimal foraging theory; and (4) the knowledge fishers have of the biology and ecology of species and their LEK, based on studies of the ethnobiology, ethnoecology, and ethnotaxonomy of fish. Considering the availability of publications on topics 1 and 2, illustrative cases are shown using optimal foraging models in Itaipu Beach, Rio de Janeiro and São Paulo Bagre, Cananéia, São Paulo, and using common snook, Centropomus undecimalis, as an example for a target species. Finally, local programs including training courses using both scientific and local knowledge are proposed within coastal artisanal fisheries.  相似文献

Marine resource management programs face conflicting mandates: to scale-up marine conservation efforts to cover larger areas and meet national and international conservation targets, while simultaneously to downscale and decentralize management authority to resource users and local communities. These conflicting goals create tensions in marine resource management. This paper explores these tensions by presenting and evaluating the outcomes of a fisheries co-management program on the island of Pemba, Tanzania, where institutions and scale were configured and reconfigured under externally funded programs to improve marine conservation through co-management. The initial institutional arrangements for co-management supported a functioning system to protect marine resources, ensure fishermen’s access, and distribute tourism revenues. However, a subsequent push to scale-up marine management reconfigured institutional arrangements and power in a more hierarchical and potentially weaker system. With the expansion of the co-management program, protected area coverage, financial resources, and the number of community organizations created for fisheries co-management expanded tremendously; however, community participation in marine management decreased, and the fishermen’s association previously involved in co-management dissolved. Several factors contributed to this outcome: inadequate time to solidify co-management institutions and arrangements, diverse resource users inexperienced with local management, a sudden and substantial new source of funding, and political pressures to restructure marine management. Rather than focusing primarily on expanding coverage and devolving authority, it is important to adapt co-management arrangements to the local contexts in which they operate.  相似文献

The goals of Integrated Water Resources Management (IWRM) can be achieved by embracing the principles of distributive governance, which places both customary and statutory water institutions on the same pedestal in the governance of water resources. As culture and traditions constitute intangible aspects of water resources management in rural Africa, the recognition of water governance systems grounded in local norms, which correspond better with the aspirations of local water users as against the expert-knowledge systems is desirable. Following the introduction of the statutory institutions in postcolonial Africa, customary institutions, which were once effective in regulating water resources became relegated to the background in those countries, including Botswana . Adopting a critical literature review approach, this article employs the concept of legal pluralism to analyze the institutional factors that create the disharmony between cultural and statutory water governance and management institutions. Findings indicate that water has been abstracted from its social nature and transformed into a tradable economic good. Ultimately, the local meanings and images encoded in water as a nature-given resource are overlooked, thus generating conflicts in water governance. The paper recommends the adoptions of legal pluralism under which water institutions need to embrace both customary and statutory institutions.  相似文献

Mainstreaming climate change adaptation (CCA) into plans and programs is still a new approach in adaptation and thus there is limited information on how to operationalize it on-ground. This paper addresses this gap by investigating the challenges in mainstreaming CCA into the local land use plans in the province of Albay, Philippines. Specifically, this paper developed 20 quantitative “mainstreaming indicators” to assess the state-of-play and the challenges for local mainstreaming. These indicators were classified under three groupings, namely, the information, institutional, and resource capacities of systems. Qualitative analysis of the indicator scores suggested that developing the institutional capacities of local governments is crucial in the local mainstreaming process. Likewise, the results highlighted the “institutional issues” indicator as the primary barrier in operationalizing the approach. These institutional issues are: fragmented laws and regulations; overlapping policy requirements; and the lack of guidelines for mainstreaming CCA into the local land use plans. Meanwhile, the “leadership” indicator, as signified by a climate change champion in Albay, was evaluated as an opportunity for local mainstreaming. The champion effectively led the CCA efforts because the existing institutional mechanisms supported the champion’s capacity to influence the behavior of people and produce collective action towards CCA.  相似文献

Systems of Knowledge: Dialogue, Relationships and Process   总被引:1,自引:0,他引:1  
During the last 20 years, the existence of rich systems of local knowledge, and their vital support to resource use and management regimes, has been demonstrated in a wide range of biological, physical and geographical domains, such as agriculture, animal husbandry, forestry and agroforestry, medicine, and marine science and fisheries.Local knowledge includes empirical and practical components that are fundamental to sustainable resource management. Among coastal-marine fishers, for example, regular catches and, often, long-term resource sustainment are ensured through the application of knowledge that encompasses empirical information on fish behaviour, marine physical environments, fish habitats and the interactions among ecosystem components, as well as complex fish taxonomies. Local knowledge is therefore an important cultural resource that guides and sustains the operation of customary management systems. The sets of rules that compose a fisheries management system derive directly from local concepts and knowledge of the resources on which the fishery is based.Beyond the practical and the empirical, it is essential to recognise the fundamental socio-cultural importance of local knowledge to any society. It is through knowledge transmission and socialisation that worldviews are constructed, social institutions perpetuated, customary practices established, and social roles defined. In this manner, local knowledge and its transmission, shape society and culture, and culture and society shape knowledge.Local knowledge is of great potential practical value. It can provide an important information base for local resources management, especially in the tropics, where conventionally-used data are usually scarce to non-existent, as well as providing a shortcut to pinpoint essential scientific research needs. To be useful for resources management, however, it must be systematically collected and scientifically verified, before being blended with complementary information derived from Western-based sciences.But local knowledge should not be looked on with only a short-term utilitarian eye. Arguments widely accepted for conserving biodiversity, for example, are also applicable to the intellectual cultural diversity encompassed in local knowledge systems: they should be conserved because their utility may only be revealed at some later date or owing to their intrinsic value as part of the world's global heritage.At least in cultures with a Western liberal tradition, more than lip-service is now being paid to alternative systems of knowledge. The denigration of alternative knowledge systems as backward, inefficient, inferior, and founded on myth and ignorance has recently begun to change. Many such practices are a logical, sophisticated and often still-evolving adaptation to risk, based on generations of empirical experience and arranged according to principles, philosophies and institutions that are radically different from those prevailing in Western scientific circles, and hence all-but incomprehensible to them. But steadfastly held prejudices remain powerful.In this presentation I describe the 'design principles' of local knowledge systems, with particular reference to coastal-marine fishing communities, and their social and practical usefulness. I then examine the economic, ideological and institutional factors that combine to perpetuate the marginalisation and neglect of local knowledge, and discuss some of the requirements for applying local knowledge in modern management.  相似文献

Abstract

This paper examines the role and effectiveness of local institutions in the management of forest biodiversity in New Dabaga-Ulongambi Forest Reserve, Tanzania. Data were obtained through questionnaires, interviews, focus group discussions, participatory rural appraisal and field observations. The study revealed that the most remarkable local institutions connected to forest biodiversity management include: Village Natural Resources Management Committee (92%), tree nursery group (79.4%), beekeeping groups (61.1%), fish farming (43.3%), livestock rearing group (33.9%). Main activities carried out by local institutions which directly contribute to the sustainability of forest reserve include: forest patrols, fire extinguish, preparation of fire breaks, planting of trees along the forest boundaries, creation of awareness, arresting of forest defaulters, participation in income generation activities. For the purpose of realization that local communities are capable of managing forest biodiversity through their traditional institutions, the policy should provide tangible opportunity for local communities to meet their needs as they manage the forests.  相似文献

This study analyzes the fishing areas or spots used by artisanal fishers of the Atlantic Forest coast. Fishers include inhabitants of islands of the SE Atlantic Forest in Brazil. Data on fish landings were collected for different islands, in 1986 and 1989–1990, for species caught, technology used and fishing time. Fishing spots were marked or rechecked using GPS in 1997–1999. Fishing is performed in paddled, motorized canoes or in small boats with set gillnets or hook and line. Marine animals caught vary from place to place and include fish, shrimp, squid and crab. Spots used are very stable in time, since they did not change for about 10 years. Among other factors, technology limits the range of access of the fishers to the spots. An informal division of fishing areas or spots is observed, based on the locality of residence of the fishers. The mapping and observed division of fishing spots may be used in local management, helping to control the intrusion of industrial fishers in artisanal areas. Local rules and discrimination of spot users may be helpful for artisanal fishers, especially in areas where conflicts with trawlers occur. The observed long-term stability of the use of fishing spots by artisanal fishers and conflicts with other users indicate the urgency of considering local rules for conservation purposes in Atlantic Forest coastal areas.

In Tanzania, well-defined land tenure and resource protection apply in forest reserves which account for 30% of forested land, while the remaining 70% (mostly miombo woodlands) are village and general lands with very limited protection. The aim of this study was to determine local peoples ownership rights, knowledge and institutional capacity for sustainable management of resources in forest reserves and general lands. Data were collected using participatory rural appraisal, structured and semi-structured interviews, as well as aerial photographs and landsat images. In general lands, woodlands declined by 50% between 1964 and 1996, bushlands and croplands increased by 599%, and settlements and homegardens increased by 277%. These land use and vegetation structure changes are attributed to harvesting for charcoal production and shifting cultivation. The continued decline in aerial woodland cover in the general lands suggests that common property regimes do not function in the area. Local institutional capacities are weak in enforcing control mechanisms to check the overuse of resources, which tends to approximate open access conditions. The issues of land tenure and village empowerment are not only institutional, but also political in nature. Government institutions should provide and motivate for an enabling environment, including acknowledgement of traditional knowledge, well-defined property rights and operational village by-laws. In order to ensure equity and sustainable development of natural resources, the paradigm shift in management is important whereby communal goods are to be managed for the benefit of the local society.  相似文献

Hot spots in Brazil include a variety of ecosystems, such as mangroves, forests, and the Brazilian savannah, locally called cerrado. Some of the rural populations in these hot spots are the caiçaras in SE Atlantic Forest coast, and the caboclos in the Amazon. In this study, we are concerned especially with the knowledge of caiçaras and caboclos, associated with practices that might have implications for management. Data were gathered through interviews with adults at the various communities studied, and through systematic observations, including samples of fishing trips and the mapping of fishing spots used in the Atlantic Forest coast. The use of resources from the surrounding vegetation includes collection of plants, cultivated fruit gardens, the swidden system, and a careful and managed extraction of fibres. Among animal resources, food taboos seem to be useful practices that might contribute to the maintenance of local natural resources. Potential management practices should be locally developed, such as the informal division of fishing spots in Atlantic Forest sites, and the maintenance of the diversity of cassava varieties in both the Atlantic Forest and Amazonian areas.  相似文献
