Effectiveness of participatory planning for community management of fisheries in Bangladesh 总被引:1,自引:0,他引:1
This study provides statistical evidence that support for community-based management of resources was more effective when initiated through a process known as participatory action plan development (PAPD). Thirty-six sites were studied where community management of fisheries was facilitated by NGOs. All involved community participation and establishing local fisheries management institutions. However, communities were able to take up more conservation-related interventions and faced fewer conflicts in the 18 sites where a PAPD was the basis for collective action and institution development. This indicates the value and effectiveness of adopting good practice in participatory planning, such as PAPD, which helps diverse stakeholders find common problems and solutions for natural resource management. 相似文献

The article explores and examines challenges and lessons learned from the implementation of community based natural resources management (CBNRM) programmes in Ngamiland, northern Botswana. The article, based largely on primary data, with some secondary data sources, draws on the CBNRM framework, which promotes rural socio‐economic development and natural resources management. Among the key factors identified as pivotal to the success of CBNRM is broadening the consultation base during the mobilization phase of the programme to facilitate effective community participation and representation. Preparedness by both the implementing institutions and participating communities is also highlighted as key to effective mobilization. This means moving away from a conventional consultative forum, to a more multi‐faceted approach that will facilitate capturing the views of diverse user groups within the community. The article also suggests that feasibility studies are needed to address socio‐economic, political and cultural characteristics inherent in communities to guide programme implementation. To achieve increased community participation and enhance positive conservation attitudes, the article advocates a mobilization approach and practice that will effectively facilitate the process. 相似文献

Conclusion As a final thought, I want to conclude with the cliche that a problem recognized is half solved. Certainly, I cannot be accused of laying out a solution to solving the major fisheries management problems, but it is hoped that the problems managers face are now clearer. The complexity of fisheries assystems to be managed is clear to even the most casual observer. The second point, a broad theory of fisheries management, should provide a framework to categorize all of the disjointed activities that we associate with management of our fisheries resources. 相似文献

Law of the Sea negotiations and The Fishery Conservation and Management Act of 1976 create new options in fisheries management. Historical analysis of two major management programs in the United States of America, Columbia River chinook salmon (Oncorhynchus tshawytscha) and Pacific halibut (Hippoglossus stenolepis), shows two unresolved management problems. One is the innovativeness of fishermen in seeking ways to improve their harvests. The other is changing social priorities that are largely unpredictable and outside the control of fisheries managers. A method for analysis of patterning associated with management goals is illustrated. Since the general management goals are harvest improvement and more predictability, measures are used which show the adequacy of fit and reduction in variability between actual and predicted management outcomes. 相似文献

Madhupur National Park is renowned for severe resource ownership conflicts between ethnic communities and government authorities in Bangladesh. In this study, we applied the Institutional Analysis and Development framework to identify: (i) past and present informal institutional structures within the ethnic Garo community for land resource management; (ii) the origin of the land ownership dispute; (iii) interaction mechanisms between formal and informal institutions; and (iv) change in land management authority and informal governance structures. We identify that the informal institutions of the traditional community have undergone radical change due to government interventions with implications for the regulation of land use, informal institutional functions, and joint-decision-making. Importantly, the government’s persistent denial of the role of existing informal institutions is widening the gap between government and community actors, and driving land ownership conflicts in a cyclic way with associated natural resource degradation. 相似文献

Summary This paper focuses on the characteristics of sustainable development as manifested in localized contexts and situations. It examines the KASHA project in Botswana, and suggests an important conceptual link between the community and sustainable development. To convey the message that there is hope and that "Sustainable Development" is possible, the paper suggests the need to document, share, describe and talk about successful programmes like KASHA.Dr Stephen Ameyaw is currently Assistant Professor of Planning in the Faculty of Environmental Design, University of Calgary. His research interests are focused on women and development, community development, regional planning, policy and institutional development. He has conducted research in Canada, Ghana and Botswana. 相似文献

This paper used ordinary kriging to spatially map arsenic contamination in shallow aquifers of Northwestern Bangladesh (total area 35,000 km2). The Northwestern region was selected because it represents a relatively safer source of large-scale and affordable water supply for the rest of Bangladesh currently faced with extensive arsenic contamination in drinking water (such as the Southern regions). Hence, the work appropriately explored sustainability issues by building upon a previously published study (Hossain et al., 2007; Water Resources Management, vol. 21: 1245–1261) where a more general nation-wide assessment afforded by kriging was identified. The arsenic database for reference comprised the nation-wide survey (of 3534 drinking wells) completed in 1999 by the British Geological Survey (BGS) in collaboration with the Department of Public Health Engineering (DPHE) of Bangladesh. Randomly sampled networks of zones from this reference database were used to develop an empirical variogram and develop maps of zonal arsenic concentration for the Northwestern region. The remaining non-sampled zones from the reference database were used to assess the accuracy of the kriged maps. Two additional criteria were explored: (1) the ability of geostatistical interpolators such as kriging to extrapolate information on spatial structure of arsenic contamination beyond small-scale exploratory domains; (2) the impact of a priori knowledge of anisotropic variability on the effectiveness of geostatistically based management. On the average, the kriging method was found to have a 90% probability of successful prediction of safe zones according to the WHO safe limit of 10 ppb while for the Bangladesh safe limit of 50 ppb, the safe zone prediction probability was 97%. Compared to the previous study by Hossain et al. (2007) over the rest of the contaminated country side, the probability of successful detection of safe zones in the Northwest is observed to be about 25% higher. An a priori knowledge of anisotropy was found to have inconclusive impact on the effectiveness of kriging. It was, however, hypothesized that a preferential sampling strategy that honored anisotropy could be necessary to reach a more definitive conclusion in regards to this issue. 相似文献

The fisheries of Lake Victoria have reached a critical stage in their development: catches are declining, and there is increasing evidence of hardship amongst the fishing communities. In an effort to countermand the reduction in the flow of economic benefits the lake's riparian states are collaborating with international agencies to develop a fisheries management strategy that would be based on a partnership between stakeholders. One possible area for such collaboration is via the devolution of certain access controls to fishing communities. This paper describes findings from recent research and argues that notions of access are linked to community perceptions of the resource, control over it and their own individual and collective manoeuvrings designed to retain and improve livelihoods. 相似文献

Solid waste management in urban areas in Tanzania is examined from a governance point of view. Capitalising on the case of the Dar es Salaam City Council, governance is seen in terms of central–local government relationship and the relationship between local government and international, national, and community institutions and stakeholders. Major impediments to waste management in urban Tanzania include corruption, poor relations between the politicians and the general population, politics of privatisation, and political apathy. Lack of resources is seen as the least important of all the impediments. An evaluation of the governance of waste management with respect to public participation, privatisation, citizen-rights, accountability and transparency and financial efficiency is discussed. Management of solid wastes in Dar es Salaam and other urban centres in Tanzania should shift from command-and-control approaches to systems of partnerships between the public authorities and the various stakeholders on the urban scene. A community-based solid waste management approach is suggested for wider adoption. The strategic approach to this non-conventional method should be carried out through four steps: elaboration, trial, evaluation and extension to other neighbourhoods. 相似文献

It is accepted that if fisheries resources are to remain renewable and able to sustain livelihoods, appropriate management practices must be implemented. Even while fisheries management grapples to resolve single-species issues, the biological and economic interactions among species mandate that to be effective, management techniques must be based on more interactive and aggregate-level analyses. In order to implement these techniques, the actual links, and the potential impact of these links, among the fisheries must be established. Vector autoregression (VAR) analysis has the potential to play an increasingly important role in ecosystem modelling for fisheries management. This study uses VAR analysis to demonstrate the quantitative impact of certain ecosystem changes on the productivity of the carite, honey shrimp and croaker fisheries of the Gulf of Paria, Trinidad, in the particular context of the ecosystem dynamics of trophic linkages, bycatch and multispecies fisheries. Four VAR models are constructed to investigate the extent to which these factors affect the production of the selected fisheries, and to evaluate the management implications of these linkages. The empirical analysis is further evidence that, if sustainable management of fishery resources is to be achieved, management practices based on more multi-species, ecosystem approaches must replace the traditional, single-species management techniques. 相似文献

Floodplain management programs have been adopted by more than 85% of local governments in the nation with designated flood hazard areas. Yet, there has been little evaluation of the influence of floodplain policies on private sector decisions. This article examines the degree to which riverine floodplain management affects purchase and mitigation decisions made by owners of developed floodplain property in ten selected cities in the United States. We find that the stringency of such policies does not lessen floodplain property buying because of the overriding importance of site amenity factors. Indeed, flood protection measures incorporated into development projects appear to add to the attractiveness of floodplain location by increasing the perceived safety from the hazard. Property owner responses to the flood hazard after occupancy involve political action more often than individual on-site mitigation. Floodplain programs only minimally encourage on-site mitigation by the owner because most owners have not experienced a flood and many are unaware of the flood threat. It is suggested that floodplain programs will be more effective in meeting their objectives if they are directed at intervention points earlier in the land conversion process. 相似文献

Fisheries management is typically a complex problem, from both an environmental and political perspective. The main source of conflict occurs between the need for stock conservation and the need for fishing community well-being, which is typically measured by employment and income levels. For most fisheries, overexploitation of the stock requires a reduction in the level of fishing activity. While this may lead to long-term benefits (both conservation and economic), it also leads to a short-term reduction in employment and regional incomes. In regions which are heavily dependent on fisheries, short-term consequences of conservation efforts may be considerable. The relatively high degree of scientific uncertainty with respect to the status of the stocks and the relatively short lengths of political terms of office, generally give rise to the short-run view taking the highest priority when defining policy objectives. In this paper, a multi-objective model of the North Sea is developed that incorporates both long-term and short-term objectives. Optimal fleet sizes are estimated taking into consideration different preferences between the defined short-term and long-term objectives. The subsequent results from the model give the short-term and long-term equilibrium status of the fishery incorporating the effects of the short-term objectives. As would be expected, an optimal fleet from a short-term perspective is considerably larger than an optimal fleet from a long-run perspective. Conversely, stock sizes and sustainable yields are considerably lower in the long-term if a short-term perspective is used in setting management policies. The model results highlight what is essentially a principal-agent problem, with the objectives of the policy makers not necessarily reflecting the objectives of society as a whole. 相似文献

We employed the contingent valuation method to estimate the willingness to pay of the respondents to improve the waste collection system in Dhaka city, Bangladesh. Our objective was to estimate how WTP differs between respondents who received or did not receive door to door waste collection. The methodology consisted of asking people directly about their willingness to pay an additional waste collection service charge to cover the costs of a new waste management project. The mean value of WTP for areas that received waste collection service areas was higher than for residents of areas that did not but the difference was not statistically significant. The aggregate value of WTP of the respondents in Dhaka city was 7.6 million Taka (USD0.1 million). 相似文献

The problem of scale in community resource management 总被引:1,自引:0,他引:1
Jefferson Fox 《Environmental management》1992,16(3):289-297
Scale is a fundamental variable in most community resource management programs. This is true both in terms of scale as a management
concept (i.e., local, regional, and national level management) as well as a mapping concept (i.e., units on the map per unit
on the ground). Julian Steward, the father of human ecology, recognized as early as 1950 that social scientists have failed
to develop methods for incorporating the effect of scale in their work. This article seeks to determine whether methods used
in plant and animal ecology for assessing the effects of scale are applicable to community resource management. The article
reviews hierarchy theory and multiple scales, two methods (one theoretical and the other practical) for dealing with problems
that span many scales. The application of these methods to community resource management programs is examined by way of an
example. 相似文献

A watershed management framework for mountain areas is based on lessons learned from watershed management experience, social and institutional learning, and the use of a watershed management program evaluation in Nepal. The lessons led to the adoption of a subwatershed-based ecosystem approach based on local participation at the subwatershed level. An integrated watershed management framework (IWMF) consisting of eight steps with three checklists was developed focusing on improvement-oriented adaptive management. The eight steps lead to the preparation of a watershed management plan. In the process three checklists are used. While the first checklist has general questions pertaining to watershed analysis, the second allows participation analysis of stakeholders in terms of their strengths, weaknesses, opportunities and threats and opens up new prospects for further reinforcing or building new user group institutions based on consensus. The final checklist consists of hierarchical watershed management objectives, including goals, results and activities leading to a program planning matrix. The framework was applied to watershed planning in the Chure Region to compare the framework-based planning with conventional planning procedures. A significant difference in quality and substance of the output, with and without the use of the framework, suggests that an integrated framework is a useful tool for an ecosystem-based approach to natural resource management and socio-technical conservation. 相似文献

A significant improvement in river water quality cannot be expected unless nonpoint-source contaminants are treated in addition to the further treatment of point-source contaminants. If river water is sprayed over a floodplain, the consequent water filtration through the sediment profile can simultaneously remove organic matter and nitrogen in the water through aerobic and denitrifying reactions. This hypothesis was tested using lysimeters constructed from polyvinyl chloride (PVC) pipe (150 cm long, 15 cm in diameter) packed with loamy sand floodplain sediment. Water was applied to the top of the lysimeters at three different flow rates (48, 54, and 68 mm d(-1)). Concentrations of NO3 and dissolved oxygen (DO), chemical oxygen demand (COD), and redox potential (Eh) in the water were measured as functions of depth after the system reached steady states for both water flow and reactions. At the rate of 68.0 mm d(-1), a reducing condition for denitrification developed below the 5-cm depth due to the depletion of O2 by organic matter degradation in the surface oxidizing layer; Eh and DO were below 205 mV and 0.4 mg L(-1), respectively. At a depth of 70 cm, COD and NO3-N concentration decreased to 5.2 and 3.8 mg L(-1) from the respective influent concentrations of 17.1 and 6.2 mg L(-1). Most biodegradable organic matter was removed during flow and further removal of NO3 was limited by the lack of an electron donor (i.e., organic matter). These results indicate that the floodplain filtration technique has great promise for treatment of contaminated river water. 相似文献

A GIS-based protocol for the collection and use of local knowledge in fisheries management planning 总被引:1,自引:0,他引:1
Despite a heavy reliance on scientific knowledge as the primary source of information in resource management, many resources are in decline, particularly in fisheries. To try and combat this trend, researchers have drawn upon the knowledge of local resource users as an important supplement to scientific knowledge in designing and implementing management strategies. The integration of local knowledge with scientific knowledge for marine species management, however, is problematic stemming primarily from conflicting data types. This paper considers the use of spatial information technology as a medium to integrate and visualise spatial distributions of both quantitative scientific data and qualitative local knowledge for the purposes of producing valid and locally relevant fisheries management plans. In this context, the paper presents a detailed protocol for the collection and subsequent use of local knowledge in fisheries management planning using geographic information systems (GIS). Particular attention is paid to the use of local knowledge in resource management, accuracy issues associated with the incorporation of qualitative data into a quantitative environment, base map selection and construction, and map bias or errors associated with the accuracy of recording harvest locations on paper map sheets, given the complications of map scale. 相似文献
