Climate finance investments and international policy are driving new community-based projects incorporating payments for ecosystem services (PES) to simultaneously store carbon and generate livelihood benefits. Most community-based PES (CB-PES) research focuses on forest areas. Rangelands, which store globally significant quantities of carbon and support many of the world''s poor, have seen little CB-PES research attention, despite benefitting from several decades of community-based natural resource management (CBNRM) projects. Lessons from CBNRM suggest institutional considerations are vital in underpinning the design and implementation of successful community projects. This study uses documentary analysis to explore the institutional characteristics of three African community-based forest projects that seek to deliver carbon-storage and poverty-reduction benefits. Strong existing local institutions, clear land tenure, community control over land management decision-making and up-front, flexible payment schemes are found to be vital. Additionally, we undertake a global review of rangeland CBNRM literature and identify that alongside the lessons learned from forest projects, rangeland CB-PES project design requires specific consideration of project boundaries, benefit distribution, capacity building for community monitoring of carbon storage together with awareness-raising using decision-support tools to display the benefits of carbon-friendly land management. We highlight that institutional analyses must be undertaken alongside improved scientific studies of the carbon cycle to enable links to payment schemes, and for them to contribute to poverty alleviation in rangelands.  相似文献

Increased trade in non-timber forest products (NTFPs) has been promoted as one possible means to slow tropical deforestation by increasing the economic value of intact forest. A market survey of NTFPs occurring in the Capim River basin in eastern Amazonia, Brazil demonstrated that the reality for many smallholder communities in frontier and remote regions includes chronic transportation difficulties, high variability in fruit production, perishable products and lack of market expertise. In some communities, declining abundance of NTFPs due to logging and fire has resulted in a lack of forest products to even meet subsistence needs. In areas close to cities where transportation is assured and where forest clearing has eroded the natural occurrence of some valuable native NTFPs, smallholders who manage and successfully market native fruit and medicinal species are overcoming these obstacles. In frontier regions undergoing rapid transformation, however, decline in locally used and regionally marketed NTFPs currently pose detrimental consequences for communities. Findings suggest that an overemphasis on NTFP marketing has diverted attention from local livelihood, resource access and subsistence issues.  相似文献

Lowland and mid-elevational rainforests of Sri Lanka harbor a relict, endemic-rich flora which is also rich in timber and non-timber forest resources. These forests supply nearly half the total wood requirements of the country and are dwindling rapidly; management of the forests to conserve the biological richness and maintain environmental services is therefore a difficult proposition. This predicament is further compounded by the dependency of rural people on a range of non-timber forest resources for their subsistence and income. A forestry master plan recently prepared for Sri Lanka has not given adequate recognition to the important role played by non-timber forest resources in rural livelihood. This oversight is primarily due to the lack of quantitative information to justify the role of non-timber forest resources in forestry sector development. Forestry policies that ignore these resources often anger local people, leading the villagers to vent their disapproval through destructive actions such as burning timber plantations. Long-term interdisciplinary research in ecology, reproductive and soil biology, ethnobiology, silviculture, rural sociology and resource economics in progress at Sinharaja attempts to address these questions of sustainable development of forest resources in an integrated mode. While research oriented toward conservation investigates both short- and long-term ecosystem dynamics in natural and modified forest stands, utilization-oriented research probes the impact of increased human disturbance, particularly the impact of rural communities on dwindling forest resources, as well as the effect of forest conservation on rural livelihood. These studies continue to seek alternative methods of forest management which are socially acceptable, economically viable, and ecologically sustainable for multiple uses. These methods will assist in the refinement of current forest policies, forestry planning, and the implementation of new policies and plans in Sri Lanka.  相似文献

Opportunities and Challenges for Ecological Restoration within REDD+   总被引:1,自引:0,他引:1  
The Reducing Emissions from Deforestation and Forest Degradation (REDD+) mechanism has the potential to provide the developing nations with significant funding for forest restoration activities that contribute to climate change mitigation, sustainable management, and carbon‐stock enhancement. In order to stimulate and inform discussion on the role of ecological restoration within REDD+, we outline opportunities for and challenges to using science‐based restoration projects and programs to meet REDD+ goals of reducing greenhouse gas emissions and storing carbon in forest ecosystems. Now that the REDD+ mechanism, which is not yet operational, has expanded beyond a sole focus on activities that affect carbon budgets to also include those that enhance ecosystem services and deliver other co‐benefits to biodiversity and communities, forest restoration could play an increasingly important role. However, in many nations, there is a lack of practical tools and guidance for implementing effective restoration projects and programs that will sequester carbon and at the same time improve the integrity and resilience of forest ecosystems. Restoration scientists and practitioners should continue to engage with potential REDD+ donors and recipients to ensure that funding is targeted at projects and programs with ecologically sound designs.  相似文献

Several Southeast Asian states have been working feverishly to design and implement REDD policy frameworks to fulfil their commitment to global climate change mitigation. In doing so, state agencies will be challenged to design REDD plus policies that value and conserve forest carbon in ways that align with national policies and local priorities for managing forest landscapes defined by complex property rights regimes. However, as with other market-based policies, the expeditious delivery of REDD could bypass critical analysis of potential interactions with national tenure regimes, customary property rights, and local livelihoods. Drawing on the case of Palawan Island—a forested frontier island in the Philippines—we examine how nascent REDD policies can articulate with state sanctioned tenure, customary tenure, and forest uses in changing livelihood contexts. This paper draws on research among Tagbanua and Pala’wan people to illustrate how complex and changing tenure structures, commodity markets and livelihood dynamics may influence how REDD plus interventions affect indigenous customary lands and forest use. We argue that the ability of indigenous forest users to maintain stored carbon and improve livelihoods is contingent upon the ‘socio-material’ form of carbon—a commodity defined in relation to the resources and social processes of which it is part.  相似文献

Community-based natural resource management policies have been seriously criticized in the last few years. Detractors have focused either on the lack of local participation, or on the lack of ecological results. Using two of the earliest and most studied community-based natural resource management (CBNRM) initiatives in Africa (ADMADE in Zambia and CAMPFIRE in Zimbabwe), the article argues that such critics miss the actual stakes of community-based policies. These policies bring local communities into a global world, both in terms of practice and narrative. From this point of view, community-based policies must be viewed as long-term approaches to change in rural Africa, which will progressively make the local/global partition fuse into processes of continual social “mobilization”.  相似文献

Postmodernism and African conservation science   总被引:1,自引:0,他引:1  
In Africa, the movement away from traditional protectionist conservation to community-based approaches is partially related to postmodernist influences. Proposed transfrontier conservation areas will incorporate local communities, and a clearer understanding of the limitations of community-based conservation is thus needed. The sustainability of community-based conservation projects is questioned on economic and other grounds, and many African countries lack the prerequisites (ecological, demographic and sociological) for successful programmes. The romanticisation of pre-colonial societies gives undue weight to traditional systems of resource management, and we challenge the postmodernist notion that traditional peoples practised sustainable harvesting of natural resources. It is suggested that this will occur only under unlikely conditions of low human population density, lack of access to modern technology, and limited exposure to consumerism. In agriculture, postmodernists interpret the overstocking of livestock as a rational socioeconomic response, thus giving the practice unjustified legitimacy. The allied proposition that peasants enjoy a rich diversity of farming practices is largely unfounded, at least in some parts of Africa. We conclude that postmodernist thinking has had a significant negative impact on conservation science in Africa, largely by marginalising the central issue of human population pressure. Towards more effective African conservation, we suggest roles for the ecologist, for the social scientist, and for the donor community.  相似文献

The increasing deforestation with an alarming rate is the prime cause of upsetting the balance in the natural ecosystem and the livelihood of local communities. Sustainable forest management and reforestation efforts can equilibrium this destruction and maintain the protected areas. In this regard, soil management strategies for reforestation of the degraded forest land can be helpful. In this review, the potential of using biochar, a solid carbon rich product of biomass thermochemical conversion, as a soil amendment in forest soils has been discussed. The production procedures of biochar, availability of feedstocks and the biochar properties are discussed using the existing knowledge. The positive effects of biochar are soil quality depended and change with varying geographical locations. Therefore, long-term field trials examining a range of biochars, soils, and forest types are required for a better understanding of this issue. Careful planning to match biochar with the soil properties is essential to obtain maximum benefits of biochar as a soil amendment.  相似文献

Traditional resource management (TRM) is largely based on local ecological knowledge (LEK). In regions where formal institutional control of natural resources is limited due to a lack of coordination or stakeholder involvement, communities rely on TRM to manage common-pool resources. This paper examines TRM among the Sonjo in rural Northern Tanzania, with particular reference to catchment forest protection and water quality. We first document the ecological knowledge of traditional resource managers, and then describe the differences between traditionally managed water sources and formal, government managed resources. Using both qualitative and quantitative methods to examine water use, perceptions of water quality, and bacterial water quality, significant differences were detected among river basins within seasons and between seasons. Our findings indicate that the Sonjo, well known for their traditional forest conservation practices and irrigation management, may also benefit from TRM through improved water quality. The examination of traditional methods of water conservation provides insight into how communities in resource-stressed regions thrive despite seasonal droughts and flooding.  相似文献

African wildlife populations and their habitats are dwindling outside ofstate-protected areas due to escalating human demands on natural resources,while the effective enforcement of conservation legislation is impracticableacross most of the continent. A particular conservation crisis is looming insouthern Africa, where extensive wildlife areas are rapidly giving way tosubsistence agropastoralism. The concept of community-based wildlife management(CBWM) has been embraced by donor agencies as a hopeful solution in areas whereadequate wildlife resources persist and agricultural potential is marginal. Theconservation value of CBWM depends, however, on communities having specificinformation to evaluate the sustainable benefits of wildlife in comparison withalternative landuse options. Furthermore, simple but scientifically soundmonitoring procedures are required to ensure that the offtake from wildlifepopulations is kept within sustainable limits. This paper draws together keyecological issues of relevance to CBWM in southern African savannas andidentifies topics requiring further attention from ecologists. The aim is toassist conservation and development agencies in providing prompt and appropriatetechnical support to communities in areas where opportunities for CBWM stillexist but could soon be foreclosed.  相似文献

Management and sustainability of fisheries has been guided by theories and models derived from modern ecological science. Traditional ecological knowledge (TEK) has been ignored in all spheres of decision-making for management and sustainability of fisheries in East Africa. TEK guided African communities in the way they associated and interacted with the natural environment around them. Spiritual rituals, religious practices, social taboos and sacred animal totems guided the peoples on how and when to utilize the available natural resources. In the advent of modern scientific knowledge, the African traditional knowledge quickly faded away and is generally seen as irrelevant. Today the potential of TEK in the management and sustainability of fisheries in East Africa has not been realized and its status and future is unknown. TEK should be complementary to modern scientific knowledge in the management and sustainability of fisheries. This paper therefore focuses on the potential application of TEK in the management and sustainability of fisheries in East Africa and the issues that impede its application.  相似文献

The Arabuko Sokoke dryland coastal forest along the East African coastline provides a unique habitat for many endangered endemic animal and plant species. High demographic pressure with subsequent land-splitting, soil depletion in combination with erratic rainfalls and the collapse of the tourism industry are negatively affecting food security and human livelihood quality in this region. Food crops were originally produced by subsistence farming, but have now to be purchased at local- and super-markets, constituting a major financial burden for the local people. In consequence, overexploitation of natural resources from Arabuko Sokoke forest (illegal logging, charcoal burning, poaching of wild animals) increased during the past years. In this commentary we document ecosystem heterogeneity leading to high species richness. We discuss direct and indirect drivers of habitat degradation of the Arabuko Sokoke forest, and critically reflect current and future solutions. Key drivers of habitat destruction and biodiversity loss are (i) illegal timber logging and removal of woody biomass, (ii) poaching of bush-meat, (iii) exceeding of the carrying capacity by the local elephant population, restricted to Arabuko Sokoke by an electric fence, and (iv) weak governance structures and institutional confusion exacerbating illegal exploitation of natural resources. Potential solutions might be: Provisioning of additional income sources; reforestation of the surrounding areas in the framework of REDD+ activities to create a buffer around the remaining primary forest; improving governance structures that formulates clear guidelines on future usage and protection of natural resources within the Arabuko Sokoke forest; and family planning to counteract human demographic pressure and the exploitation of natural resources.  相似文献

Inshore marine resources play an important role in the livelihoods of Pacific Island coastal communities. However, such reliance can be detrimental to inshore marine ecosystems. Understanding the livelihoods of coastal communities is important for devising relevant and effective fisheries management strategies. Semi-structured household interviews were conducted with householders in Langalanga Lagoon, Solomon Islands, to understand household livelihoods and resource governance in fishing-dependent communities. Households were engaged in a diverse range of livelihoods. Fishing, shell money production and gardening were the most important livelihoods. Proximity to an urban centre influenced how households accessed some livelihoods. Perceptions of management rules varied and different reasons were cited for why rules were broken, the most common reason being to meet livelihood needs. Current models of inshore small-scale fisheries management that are based on the notion of community-based resource management may not work in locations where customary management systems are weak and livelihoods are heavily reliant on marine resources. An important step for fisheries management in such locations should include elucidating community priorities through participatory development planning, taking into consideration livelihoods as well as governance and development aspirations.  相似文献

Community-based management is increasingly viewed as the most appropriate arrangement for promoting sustainable development of natural resources. A common assumption is that the values of community members, often assumed to be homogeneous, foster successful outcomes. However, analysts often treat these values and their homogeneity as exogenous factors, ignoring the community's potential role in managing members' values. This study of community-based forest management in two southern Indiana sites examines how the members of the two communities created institutions to screen, maintain, and defend their values. Analysis reveals that different institutions shaped members' preferences and led to different levels of community stability, conflict management, and natural resource condition. We argue that understanding community-based management processes and outcomes requires careful attention to how institutions facilitate or hamper the construction of community members' values.  相似文献

A survey was undertaken in the Maputo Elephant Reserve to establish the level of people's dependence on wildlife, and their perceptions of the extant Forest and Wildlife Policy and the associated legislation, including the new Land law. The underlying assumption was that the local communities residing in the Reserve may not have been involved, or consulted in the process of formulating the policy and legislation. Results overwhelmingly confirmed this hypothesis – as 65% of the community members interviewed were unaware of the approved Forest and Wildlife Policy, and associated Legislation. 74% had never even heard of the new Land Law, 88% indicated they were not involved in any management of natural resources in the Reserve, and the majority, 53% had never even heard of any community-based natural resource management programme. The widespread unawareness of the various enabling mechanisms established by the Mozambican Government to ensure that rural people actively participate in, and sustainably and tangibly benefit from the management of natural resources is of great concern. More particularly so, as the frameworks, and strategies for achieving this have been developed under the Transfrontier Conservation Areas Project (TFCA). This study recommends, inter alia: (i) that the Directorate for Forestry and Wildlife establishes a Community Education and Public Relations Unit (CEPRU) in the Maputo TFCA in order to improve community awareness of the opportunities, and various enabling policies and legislation, especially with respect to communities' rights vis-à-vis ownership of land and the associated natural resources; (ii) the introduction of community-based tourism as a means of diversifying communities' income base. Currently nearly 82% of community members in the Reserve depend on consumptive use of wildlife, and as the human population grows the pressure may overwhelm the resource base. Generation of revenues through community-based tourism may be an incentive for communities to adopt biodiversity conservation based market economy as an alternative to their subsistence livelihood styles.  相似文献

The present and future well-being of the world’s forest dwelling populations depends on their ability to gain livelihood resources from their immediate environment. Sustainable extraction of non-timber forest products has been promoted by conservationists and development agencies as a feasible strategy for forest dwellers that does not compromise the resource base. Yet surveys of actual resource use suggest that for poorer resource-dependent communities without access to markets, non-timber forest products can only ever represent a safety-net activity and a supplementary income source. Others argue that resource availability, in terms of the diversity and productivity of the forest, is the key parameter in realizing a contribution of forest products to well-being. This paper examines the scope and heterogeneity of forest product use to reveal whether resource availability necessarily provides the context for significant contributions to well-being of forest dwellers. We present data from an area of tropical rainforest, close to Iquitos in Peru, which was previously shown to have high potential value. We find, through a census survey of households within a forest reserve area, that non-timber forest products provide only a relatively small portion of income and that only a small proportion of available products are actually commercialized, despite apparent market availability. We show that the low rates of commercialization can be explained by unequal access capital assets used for extraction, to natural resources themselves, and to product markets. They are also explained by the concentration of capital-poor households on subsistence gathering activities. The value of destructive uses of forests, both logging and agriculture, remain higher than returns from non-timber products. This research demonstrates that although non-timber forest products are an important livelihood source, market integration and commercialization is not everywhere an appropriate or realistic strategy.  相似文献

We propose improvements for addressing the inadequate sustainable use of wildlife resources in the community-based natural resource management (CBNRM) programme in game management areas (GMAs) using case study data from Mumbwa and Lupande GMAs in Zambia. Firstly, we assess the sustainability of wildlife resources in these GMAs using design principles for enduring common pool institutions. Secondly, we propose the steps required to address the lack of sustainability of wildlife resources in the CBNRM programme in the two GMAs by building on indicators suggested by Ostrom's principles. The resource use patterns in the two GMAs were assessed according to their socio-economic and institutional factors. Comparisons were made between the two GMAs in relation to Ostrom's design principles. Accordingly, the combination of socio-economic and institutional factors restrains the sustainable use of wildlife resources in the two GMAs. Unless the Zambian government provides local communities with meaningful decision-making powers and benefits for the utilisation and management of wildlife, this resource is likely to disappear outside national parks.  相似文献

The literature on locally-based monitoring in the context of conservation of ecosystems and natural resources in developing countries displays a great deal of optimism about its prospects as a low-cost approach to gather information about conservation outcomes. Yet, this optimism stands in stark contrast to studies on co-management between States and local communities showing that such processes—in which communities and the State ostensibly work hand in hand on the monitoring and management of natural resources—are fraught with power struggles within communities as well as between communities and the State and that the information produced and communicated is often invoked in such struggles. Information produced and communicated in systems of locally-based monitoring will reflect these struggles in particular if such systems are bound up with processes of co-management or REDD+ in which the information can be perceived by those who monitor to be linked to claims over resource rights and associated benefits. In such situations, trust in locally-based monitoring should be tempered by scepticism and systems of checks and balances.  相似文献

Because industrial agriculture keeps expanding in Southeast Asia at the expense of natural forests and traditional swidden systems, comparing biodiversity and ecosystem services in the traditional forest–swidden agriculture system vs. monocultures is needed to guide decision making on land-use planning. Focusing on tree diversity, soil erosion control, and climate change mitigation through carbon storage, we surveyed vegetation and monitored soil loss in various land-use areas in a northern Bornean agricultural landscape shaped by swidden agriculture, rubber tapping, and logging, where various levels and types of disturbance have created a fine mosaic of vegetation from food crop fields to natural forest. Tree species diversity and ecosystem service production were highest in natural forests. Logged-over forests produced services similar to those of natural forests. Land uses related to the swidden agriculture system largely outperformed oil palm or rubber monocultures in terms of tree species diversity and service production. Natural and logged-over forests should be maintained or managed as integral parts of the swidden system, and landscape multifunctionality should be sustained. Because natural forests host a unique diversity of trees and produce high levels of ecosystem services, targeting carbon stock protection, e.g. through financial mechanisms such as Reducing Emissions from Deforestation and Forest Degradation (REDD+), will synergistically provide benefits for biodiversity and a wide range of other services. However, the way such mechanisms could benefit communities must be carefully evaluated to counter the high opportunity cost of conversion to monocultures that might generate greater income, but would be detrimental to the production of multiple ecosystem services.  相似文献
