Natural resources, especially the forest provide a means of livelihood to rural communities in most developing countries. Unfortunately these resources are under the threat of disappearing because of high population growth rates and poverty that characterise these communities. Any attempt by development agencies at conserving these resources is tantamount to depriving these rural areas of their survival base. Yet due to its strategic socio-economic and cultural importance, the forest ecosystem needs to be sustained for future generations. This paper examines the various challenges faced by the State and other conservation agencies in natural resource management and the possible options which can be employed in an effort to ensure a sustainable exploitation of the forest in Anglophone Cameroon. It discusses the efforts of these actors, within the framework of the emerging concept of community forestry, local community strengthening and integrated rural development. While highlighting some of the achievements of international NGOs like Bird Life International and World Wide Fund for Nature in the region, the study concludes that the future of sustainable management of forest resources relies on a holistic poverty alleviation approach that takes into consideration the empowerment of these communities. This will ensure that they participate and benefit from the exploitation of the resources in the form of local development. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

A study was conducted in four selected upazilas under four coastal districts through participatory rural appraisal (PRA), household survey and monitoring, sampling, focal group discussions, personal interview, onfarm field visits, institutional consultations, and secondary information. The investigation revealed that the valuable natural resources of the whole region are at the verge of serious degradation. Various causes have been identified, which are responsible for degradation of both resources and production environments. These causes include human population growth, coastal embankment, upstream withdrawal of Ganges water, brackish water shrimp farming, salt production, use of agro-chemicals, industrial activities, commercial activities, over-exploitation, etc. The study also showed that the degradation of natural resources is the reason behind the squeezing of historically dominant livelihood opportunities of the coastal communities. The current scenarios of the coastal ecosystem urge necessary steps to be taken for sustainable management of valuable resources and to create alternative livelihood opportunities for the coastal communities.  相似文献

Conservation practitioners have scrutinized the credibility and effectiveness of community-based natural resource management, noting its romantic misconceptions about communities and their capacities. Early approaches failed to acknowledge the heterogeneity of collective agents, the synergy between decentralization and neoliberalism, or the need to affirm rural peoples’ entitlements to resources. A Maori community’s attempt to restore Lake Whakaki on New Zealand’s east coast confirms many of these critiques. The restoration confronts institutional ambivalence, obstructive forces from beyond the zone of Maori influence and non-correspondence between community and catchment dynamics. Fulfilment of the project requires exogenous resources and authority, but state conservation agencies are ambivalent towards local demands for self-determined development. Nonetheless, an uncommon degree of agency which is grounded within community aspirations for sovereignty suggests that the motivational characteristics of community retain their importance in debates about integrated conservation and development.  相似文献

Pro-poor water engineering aims to deliver water services to individuals and communities in a manner that yields obvious and significant net-benefits to the poorest people. Technology transfer in the field of pro-poor water engineering has too often been seen as one-way (north to south), with industrialised nations exporting their supposedly superior technologies and organisational priorities to the ‘grateful poor’ in the under-developed world. While north-to-south technology transfer can boast significant successes, failures are more numerous, arguably due to the contrast between technocratic (northern) and communitarian (southern) traditions of water management. There is much the northern countries might learn from the southern perspective. One concrete example illustrates how direct experience of community-based, NGO-fostered development of borehole water supplies in Bolivia led to the conscious adaptation of this model for application to problems of remediation of severe contamination of streams in a former mining district in the UK. This application was highly successful, leading to the development of robust community organisations that have gone on to tackle other social and environmental problems. This experience has in turn prompted the testing of the low-cost, technological approaches to acid drainage treatment developed in the UK case for potential application to similar problems in Bolivia. Following further ‘acclimatisation’ of the technology, field trials proved successful and led to plans for full-scale application of the approach with community-based NGOs in Bolivia. Lessons are drawn for furthering the implementation of pro-poor, participative strategies in water management in both the North and the South, with brief critical analyses of Participación Popular in Bolivia, and of both policy and polity in relation to community engagement in aspects of water management in Europe.  相似文献

This paper explores social, and economic aspects of coastal communities crucial to the management of estuaries in the Pacific Northwest. These aspects include the changing demographics and economies of coastal communities, and the public perceptions, attitudes, and values pertaining to estuarine ecosystems. Information from Willapa Bay and Grays Harbor in Washington and Tillamook, Yaquina, and Coos Bays in Oregon shows that the coastal communities are growing more slowly than the states overall., that the populations are relatively old, and that, although the local economies continue to rely on them, the extractive natural resource industries (fishing, aquaculture, agriculture, forest products) are declining in importance relative to tourism, recreation, and retirement industries. These trends suggest that human uses of the estuaries are changing in character, and altering the management problems. Coastal residents choose to live in these communities to enjoy the views and scenery, to experience rural living, to be near the ocean, and to recreate outdoors. People express coherent perceptions of risks to the estuaries, especially the threats of declining fish habitats, oil spills, shoreline development, invasive species, and logging in upland areas> Residential land values are enhanced by the presence of wetlands and forests and are diminished by the presence of hazardous waste sites. We conclude that, if recent trends in population age structure, income sources, and employment status continue, public attitudes and values will move towards stronger environmental protection. Because ecosystem management involves local public participation and collaboration, estuarine managers will be faced with both increased demands and opportunities.  相似文献

Transfrontier conservation has taken Southern Africa by storm, where the modus operandi remains simple and intuitive: by dissolving boundaries, local benefits grow as conservation and development spread regionally. However, in the case of South Africa’s section of the Great Limpopo Transfrontier Park, political and economic change redirects benefits to support ‘modern’ economies at the expense of rural livelihoods through community-based natural resources management (CBNRM). Neo-liberal agendas promoted by government and the transfrontier park derail efforts at decentralizing CBNRM initiatives beyond markets and state control. This paper argues that ‘hybrid neoliberal’ CBNRM has arisen in private and public sector delivery of devolved conservation and poverty relief projects as ‘tertiary production’ for regional development. As a result, ‘CBNRM’ projects related to and independent of transfrontier conservation support private sector interests rather than the resource base of rural livelihoods. Concluding sections assert that CBNRM can counter this neoliberal trend by supporting the land-based economy of local users living near the Great Limpopo Transfrontier Park.  相似文献

Groundwater is an important and readily available source of fresh water in the Mekong-Lancang River Basin. With a rapid population growth and increasing human activities, an increasing number of countries in the Mekong-Lancang River Basin are experiencing depleted and degraded groundwater supplies. In transboundary river basins, such as the Mekong-Lancang River, prioritizing the use of the shared aquifer by one riparian government may affect the opportunities of other riparian governments and lead to potential water conflicts between neighboring countries. To promote the sharing of strategies and information for the sustainable and equitable use of water resources of the shared basin, international collaborative workshops on groundwater resources have been organized for all Mekong-Lancang River countries. These workshops provide an opportunity to communicate and discuss nationally sensitive issues on groundwater by the associated countries, with topics covering multiple aspects of groundwater, such as the groundwater status in the basin, quality issues, water use conflicts, hydrological information gaps, management policies and capacity building for successful water resource management. Consensus has been reached by all countries on the importance of catchment-based groundwater management and the need for close communication among the countries. Strategies for managing transboundary aquifer issues must foster international collaboration based on the regional network, influence national networks and enhance the capacity to building maps and monitoring systems based on associated databases. The sustainability of water resources cannot be achieved without the integrated involvement and contributions by multiple countries and various stakeholders. Therefore, collaborative workshops provide a great opportunity to further our understanding of the hydrologic processes of the Mekong River Basin, share the benefits of the aquifer and provide a strategy and vision for sustainable water resource management in the Mekong-Lancang River countries.  相似文献

Water resources in northern Cameroon have continuously been reducing over the past years. Many studies have suggested two principal causes: (1) human activities such as poor farming practices, unsustainable use of water resources, increased demand of water, deforestation, land-use change, etc., (2) human-induced climate change. Northern Cameroon in this study includes: the Adamawa, North and Far North regions located closer to the Sahel regions of Africa. These regions are already water stressed because of their location and any further change in climate with rising temperature would impact water resource either positively or negatively. Time series analysis and a 12-month standardized precipitation index (SPI12) with digital data between 1957 and 2006 were used to investigate the variation of water resources in northern Cameroon. Results obtained varies between the different regions with an increased annual trend in temperature and precipitation for Ngaoundere (Adamawa region) and Garoua (north region), whereas Maroua (far north region) had a decreased annual trend in both precipitation and temperature. Further variability results obtained from a SPI12 show that wetter period out number drought period in all three regions. The study concluded that water resources vary with the changing climatic condition and the severity of the impact varies from region to region. Furthermore, water deficiency in northern Cameroon might not be due to climate change. The reasons might be a combination of poor water management and other factors such population growth, the environmental condition, etc.  相似文献

The CAMPFIRE program in Zimbabwe is one of a `new breed' of strategies designed to tackle environmental management at the grassroots level. CAMPFIRE aims to help rural communities to manage their resources, especially wildlife, for their own local development. The program's central objective is to alleviate rural poverty by giving rural communities autonomy over resource management and to demonstrate to them that wildlife is not necessarily a hindrance to arable agriculture, “but a resource that could be managed and `cultivated' to provide income and food”. In this paper, we assess two important elements of CAMPFIRE: poverty alleviation and local empowerment and comment on the program's performance in achieving these highly interconnected objectives. We analyze the program's achievements in poverty alleviation by exploring tenurial patterns, resource ownership and the allocation of proceeds from resource exploitation; and its progress in local empowerment by examining its administrative and decision making structures. We conclude that the program cannot effectively achieve the goal of poverty alleviation without first addressing the administrative and legal structures that underlie the country's political ecology.  相似文献

甘肃河西地区内陆河流域荒漠化的水资源问题   总被引:25,自引:1,他引:24  
河西地区内陆河流域荒漠化的水资源问题,根本的原因在于水资源短缺而导致的生态环境脆弱和水资源的过度开发利用.如果上、中游地区水资源的利用超过了水资源量的限度,则流到下游的径流量减沙,地下水位下降;而下游地区为了弥补水资源的不足,便大量开采地下水,致使地下水严重超采,从而导致植被退化和荒漠化.在分析上述问题的基础上,以石羊河为例,说明内陆河流域的荒漠化防治要求实行以农业节水为中心,建立节水型社会的流域综合治理,实现水资源、土地资源、经济、社会和生态环境协调和可持续发展.  相似文献

Indigenous people often exclusively depend on the natural resources available within the ecosystems where they live, and commonly manage their resources sustainably. They have developed, and continue to develop indigenous knowledge systems which encompass sustainable management of natural resources. This study compares indigenous knowledge of natural resource management developed by two different communities in two different environments—Maori in the temperate environment in New Zealand and Dusun in the tropical environment in Brunei Darussalam, and comparatively evaluates the role of indigenous knowledge in sustainable resource management in three categories of knowledge such as spatial and seasonal distribution of natural resources, sustainable harvesting, and habitat management. The comparison reveals that despite the differences in environment and the great geographical distance between the two communities, there are remarkable similarities between the two knowledge systems in concepts, principles, strategies and technologies used in natural resource management.

The impact of water-borne disease in South Africa is significant. An estimated 43,000 deaths per annum, including 20% of deaths in the 1-5 years age group, are directly attributable to diarrhoeal diseases. Drinking water quality provision in many rural areas is substandard. This paper describes the results of sampling drinking water supplies in rural communities in the Western and Eastern Cape, South Africa. The majority of samples collected failed microbial drinking water quality standards. Overall, schemes dependent on groundwater provided a worse quality water at point of use than surface-water-dependant schemes. This is thought to be the result of pump breakdown, deterioration of the storage and reticulation system, and insufficient monitoring and management of the schemes. Importantly, it is shown that the implementation of well-considered, community accepted drinking-water quality management procedures can effectively change an unacceptable water quality to one that satisfies drinking-water specifications.  相似文献

流域水资源合理配置的研究进展与发展方向   总被引:80,自引:0,他引:80       下载免费PDF全文
水资源合理配置是实现水资源可持续利用的有效调控措施之一。将现状的水资源合理配置研究划分为广义和狭义两类,进而从内在机制、实践进程和评价三方面系统综述了狭义流域水资源合理配置研究进展。指出目前中国在流域水资源配置过程中存在若干问题,主要表现为缺乏有效的初始水权分配机制、缺乏有机的补偿和机理机制、缺乏广泛的社会参与机制和缺乏系统的后效评价体系,致使现状水资源配置难以实现真正意义上的合理。为解决上述配置实践中存在的相关问题,今后我国水资源配置研究的重点主要集中在建立符合现代流域水循环过程的"天然 人工"二元认知模式,建立以水循环为基础的水资源合理配置模式、建立具有统一基础的水资源配置准则和建立水资源配置合理性评价标准和体系等。  相似文献

In 1991 the people of the town of Kumbo in Northwest Cameroon expelled the national water corporation from town by force. They claimed to be retrieving a network that the community rightfully owned and they began to run the system along community lines. The paper tells the story of that water supply twice. First it reproduces the popular accounts that circulated in the 1990s that emphasize the role played by the community in the development and operation of the water supply and portray recent events as a triumph of community management. Then it retells the story using archive evidence that puts a quite different light on some of the events. It is argued that the emphasis on community management has a tendency to obscure other important aspects of the story, for example its political context and consequences. It is suggested that the widespread admiration for any initiative that is community based often results in an uncritical analysis of this form of development project. In this case the commodification of water accelerates after the community has wrested control of this public service from the state.  相似文献
