Community forestry is expanding in developing countries but there is limited knowledge of, and contradictory findings about, its contribution to biodiversity conservation. This study aims at increasing the understanding of tree species diversity in community forests compared to National Parks. A forest inventory was carried out in four community forests and one National Park in the mid-hills of central Nepal. The study found that community forestry has contributed to high tree species diversity where forest management communities have interests in multiple species, but most community forests are moving toward promoting limited timber yielding species that have high economic value. Linking community forestry with economic incentives for conserving multiple tree species could therefore be a strategy to conserve biodiversity outside of protected areas.  相似文献

Community based forestry is seen as a promising instrument for sustainable forest management (SFM) through the purposeful involvement of local communities. Globally, forest area managed by local communities is on the rise. However, transferring management responsibilities to forest users alone cannot guarantee the sustainability of forest management. A monitoring tool, that allows the local communities to track the progress of forest management towards the goal of sustainability, is essential. A case study, including six forest user groups (FUGs), two from each three community based forestry models—community forestry (CF), buffer zone community forestry (BZCF), and collaborative forest management (CFM) representing three different physiographic regions, was conducted in Nepal. The study explores which community based forest management model (CF, BZCF or CFM) is doing well in terms of sustainable forest management. The study assesses the overall performance of the three models towards SFM using locally developed criteria (four), indicators (26) and verifiers (60). This paper attempts to quantify the sustainability of the models using sustainability index for individual criteria (SIIC), and overall sustainability index (OSI). In addition, rating to the criteria and scoring of the verifiers by the FUGs were done. Among the four criteria, the FUGs ascribed the highest weightage to institutional framework and governance criterion; followed by economic and social benefits, forest management practices, and extent of forest resources. Similarly, the SIIC was found to be the highest for the institutional framework and governance criterion. The average values of OSI for CFM, CF, and BZCF were 0.48, 0.51 and 0.60 respectively; suggesting that buffer zone community forestry is the more sustainable model among the three. The study also suggested that the SIIC and OSI help local communities to quantify the overall progress of their forestry practices towards sustainability. The indices provided a clear picture of forest management practices to indicate the direction where they are heading in terms of sustainability; and informed the users on issues to pay attention to enhance sustainability of their forests.  相似文献

There is an increasing recognition of the contribution of forests to food security of poor and marginalized people. However, empirical findings remain limited on how forests contribute to food security. Drawing on four case studies of community forestry in Nepal, this paper discusses pathways through which forests are contributing to food security needs of local communities. The evidence presented here was gathered through 4 years of action research and draws insights from the past 40 years of Nepal’s community forestry practice, which is often regarded as a successful case of conservation and development. It is shown that there are four distinct pathways through which community forests contribute to food security as a source of: (1) income and employment; (2) inputs to increase food production; (3) directly for food; and (4) renewable energy for cooking. Despite emerging pathways linking forest management to food systems at the local level, forestry policies and institutions have neither explicitly recognized nor strengthened the linkage between forest and food security. The paper highlights that there is a need for a fundamental shift in thinking from the conventional notion of ‘forests for soil conservation’ to ‘sustainable forest management for food security’.  相似文献

The status of forest conditions before and after intervention of the forestry projects in community forest in three districts of Nepal is examined. Benefits are observed from the adoption of adaptive collaborative management and collective learning and action research in three sampled districts. The adoption of regular silvicultural treatments has increased the availability of forest products to local users. Moreover, improved forest condition and smallholder livelihoods have improved, as has environmental sustainability. However, the community forestry program has several limitations and shortcomings. Elite capture, social disparity, inequitable benefit-sharing and exclusion of poor and marginalized groups from the community forestry program are notable challenges to be solved in coming years. Special attention is needed to make community forestry inclusive with equitable benefit-sharing and a pro-poor focus.  相似文献

Community forestry has been characterized as a successful model of community-based forest governance in Nepal that shifts forest management and use rights to local users, often socially heterogeneous in caste, gender and wealth status. This heterogeneity forms the basis of social groups, which differ in their needs, priorities and perceptions regarding community forestry implementation processes. This paper explores the dynamics of three community forestry processes—users’ participation, institutional development, and decision-making and benefit-sharing—among forest user groups as perceived by three social groups of forest users—elite, women and disadvantaged—from eight community forests of Dhading district, Nepal, using qualitative and quantitative techniques. It is found that social groups have differing levels of perception about community forestry processes occurring in their user groups. In particular, social elites differ from women and disadvantaged members of the group in users’ participation in community forestry activities and institutional development of forest user groups. An important policy implication of the findings is that social inclusiveness is central to the effective implementation of community forestry processes, not only to safeguard its past successes but also to internalize the economic opportunities it poses through reducing deforestation and forest degradation in the future.  相似文献

Nepal's forests have been transferred to community management with the twin objectives of supplying forest products and addressing local environmental problems. Community forests provide a range of benefits, from direct forest products such as timber and non-provisioning ecosystem services such as soil protection. There is a need to understand the extent to which environmental and community benefits are joint products or substitutes. Stochastic frontier production analysis (SFPA) was used to study the production relationship between environmental and community benefits and production efficiency analysis to study the extent to which communities were able to achieve maximum benefits. SFPA indicated that the magnitude of direct forest product benefits was influenced by various socioeconomic and forest related factors such as distance to the government office, community forest size, and group heterogeneity negatively affect community forest products benefits. On the other hand, links to the market, forest products dependency, and the number of households in the community augment benefits from community forests. In addition, forest product benefits and environmental benefits were complementary to each other. Production efficiency analysis showed that communities were not producing forest products efficiently. Factors such as social capital contributed positively to production efficiency, whereas caste heterogeneity in the executive committees of community forest user groups was negatively associated with efficiency. These findings can contribute to better implementation of community forestry programmes in Nepal, improving the welfare of communities by increasing direct forest product benefits without environmental harm.  相似文献

Sal (Shorea robusta Gaertn. f.) forests cover over 11 millionha in India, Nepal and Bangladesh, and these forests are conventionallymanaged for timber. Recently, interest in producing multipleproducts from sal forests has increased; accordingly, a silviculturalregime for managing sal forest for multiple products is a centralconcern. Forest managers need a comprehensive scientific understandingof natural stand development processes and anthropogenic factorsaffecting sal forest when designing silvicultural regimes formultiple-product management. We review ecology and productivityplus anthropogenic niches of sal forests. Information on edaphicfactors, phenology and stand development processes (regeneration,growth characteristics, soil nutrient requirement, growth allocation,nutrient cycling, stand structure and successional stages) isimportant for designing scientific forest management of salforest; likewise, knowledge of anthropogenic factors associatedwith use of sal forest is also required for effective implementationof the recently paradigmed management efforts. Sal forest silviculturehas been evolving since the beginning of the twentieth centurymainly concentrating on timber production, though the sal forestshave always been used also for grazing and collection of fodder,fuelwood, litter and many other products. Instead of integratingthese products in sal forest management, governments have attemptedto control these additional uses through enforcing forest legislation.These attempts resulted in the persistent conflicts betweenthe interests of local people and the government, and the deterioratingcondition of sal forests. Community-based forestry in this regionemerged in response to the severe degradation of forest resources,and local people initiated protection practices and demonstratedthe success of sal forest from coppice. The coppice systemsallow managing forests with intermittent products (non-timberforest products, including fodder and litter) while producingtimber in the long term. Accordingly, a policy has been developedto manage coppice sal forest for multiple products. Managingthe sal forest for multiple products is, however, a relativelyrecent development and scientific investigations on variousaspects of multiple-product forest management need to be initiated.Ecological processes indicate good prospects of managing salforest for multiple products. The review indicates that theecological processes and anthropogenic factors form sound basisfor developing multiple-product management.  相似文献

International and national development programs in Nepal place high priority on management of forests for biodiversity. Communities are expected to embrace and cooperate in this endeavour for biodiversity conservation, yet little research has been carried out to understand community viewpoints on biodiversity conservation, or even to ascertain people’s understanding of the concept of biodiversity. This paper explores perceptions and concepts related to biodiversity and its conservation held by people involved in community forestry in Nepal. Data were obtained from in-depth individual interviews and focus group discussions carried out in two contrasting geographical districts. The results show that the Western term ‘biodiversity’, translated into Nepalese as jaiwik bibidhata, is new and confusing to most forest people, who interpret the term in a variety of ways. People’s perceptions of biodiversity vary widely and a considerable gap exists between policy-makers and forest users in the understanding and interpretation of this Nepalese term and its related concepts. These findings have important implications for the design and implementation of development programs and in formulation of forest policy in Nepal.  相似文献

Since the 1980s many tropical countries have promoted community forestry (CF). Gradually, various forms of community forest management regimes were developed in response to decentralization processes in the forest administration or the government administration. The emergence of community forestry regime (CFR) complexes and their evolutionary pathways have still been little explored. In Tanzania, Babati District is a pioneer in the development of CF. This paper assesses how emergence of a CFR complex is related to dynamic institutional interactions at local community level and bureaucratic level. It is demonstrated that evolution and diversity of CF regimes is associated with (a) a partial bureaucratic deconcentration of the government’s administrative authority over forests from national level to district level, and (b) democratic decentralization in the form of a partial devolution of formal management authority over forests from governmental authorities to local communities and individual people. Also, it is shown that endogenous changes in the norms and principles of the traditional systems of indigenous forest management occurred, calling for formulation of policy objectives that help to sustain local management practices.  相似文献

Silviculture to maintain old-growth forest attributes appears to be an oxymoron since the late developmental phases of forest dynamics, described by the term old-growth, represent forests that have not experienced human intervention or timber removal for a long time. In the past, silvicultural systems applied to old-growth aimed to convert it into simplified, more productive regrowth forests substantially different in structure and composition. Now it is recognised that the maintenance of biodiversity associated with structural and functional complexity of late forest development successional stages cannot rely solely on old-growth forests in reserves. Therefore, in managed forests, silvicultural systems able to develop or maintain old-growth forest attributes are being sought. The degree to which old-growth attributes are maintained or developed is called “old-growthness”. In this paper, we discuss silvicultural approaches that promote or maintain structural attributes of old-growth forests at the forest stand level in (a) current old-growth forests managed for timber production to retain structural elements, (b) current old-growth forests requiring regular, minor disturbances to maintain their structure, and (c) regrowth and secondary forests to restore old-growth structural attributes. While the functions of different elements of forest structure, such as coarse woody debris, large veteran trees, etc., have been described in principle, our knowledge about the quantity and distribution, in time and space, of these elements required to meet certain management objectives is rather limited for most ecosystems. The risks and operational constraints associated with managing for structural attributes create further complexity, which cannot be addressed adequately through the use of traditional silvicultural approaches. Silvicultural systems used in the retention and restoration of old-growthness can, and need, to employ a variety of approaches for managing spatial and temporal structural complexity. We present examples of silvicultural options that have been applied in creative experiments and forestry practice over the last two decades. However, these largely comprise only short-term responses, which are often accompanied by increased risks and disturbance. Much research and monitoring is required still to develop and optimise new silvicultural systems for old-growthness for a wide variety of forest ecosystem types.  相似文献

Increased participation of local users in decision-making about forests and gaining benefits from these forests are major goals of the community forestry program in Nepal. However, there is a lack of real participation in community forest governance amongst users, particularly by poor and marginalised members. By employing a mixed-method approach, this research explores the issue of participation in the governance of community forests, and in particular the role of incentives in increasing participation. A partial least square approach is undertaken to link the participation indicators to the various incentives. Access to benefits, enforcement of legal property rights and social cohesion through building of local institutions are identified as the key influential incentives that determine the effective participation of users in community forest governance. Other incentive—including income supplements, community infrastructure development or payment for environment services—are insufficient to counter the opportunity cost of participation, and hence have a weak but still significant influence on users’ decisions to participate. Power inequality due to socio-cultural norms, together with poor economic capabilities and weak bargaining power, could undermine the meaningful participation of poor and disadvantaged groups in the governance of community forests, unless the community forestry institutions are strengthened in order to be able to deal with the issues of inequitable access and restricted opportunities at the local level.  相似文献

Following the introduction of planned forestry and the regular high forest system more than 250 years ago, forests in Central Europe became increasingly shaped by plantation silviculture. Many natural woodlands were replaced by planted forests, and forest plantations are still being established through afforestation of extensive land areas. Nowadays, forests are managed for many different purposes, including wood production, recreation, ecological, cultural, and amenity values, biodiversity, and soil and groundwater protection. This brings new challenges to forest management and silviculture. To reach a sustainable forestry, in the sense of Brundtland (WCED 1987), we are now reshaping European forestry toward a more nature oriented silviculture. Maybe forestry in the United States and elsewhere can benefit from the mistakes made in Europe during the last two centuries and take a shortcut toward sustainable forestry.  相似文献

Community forestry is an emerging success model of state–community partnership for forest management and poverty reduction. Bhutan's initial experience of forest management by user group is promising, but merits further study on how community forests have experienced with harvesting and income generation consistent with national forest policy. This study quantifies whether community forestry contribute to household income with equitable products and income distribution and gender inclusive participation; and community forests are managed applying the principles of sustainable harvest without compromising regeneration and productivity. We applied a combination of social and ecological methods using household interview and forest sampling plots. Our findings revealed that community forestry contributes to household income through harvesting and marketing of large trees, and non-wood forest products where markets are accessible. Household income, however, vary widely between rich and poor households with former capitalizing on commercial and latter on subsistence products. Timber harvesting is consistent with the principles of sustainable harvest without altering species composition, regeneration and productivity. To narrow income inequality, pro-poor approach to community forestry needs to target poor households with income diversification activities and market accessibility. The promising results are context-driven and warrant consolidation from other community forests experiencing harvest in Bhutan.  相似文献

This article examines the current state of community forestry in Laos. The rationale for community forestry in the Lao context is presented, followed by a discussion of the development of the Lao version of community forestry, called participatory sustainable forest management (PSFM). The history of a project supported by an international non-government organization that attempted to implement PSFM and that was subsequently discontinued by the Lao government is then presented, followed by an analysis of the reasons for government opposition to the project. Examples of more successful community forestry systems in two countries—Nepal and Mexico—are contrasted with Laos's state-centered PSFM model. Lessons from these countries suggest that fundamental institutional changes are necessary for community forestry to take hold in Laos.  相似文献
