The Sanjiang Plain is a vast area of alluvial floodplains and low hills in northeast Heilongjiang Province. It is the largest tract of wetlands in China and East Asia outside of Siberia. 28 wetland nature reserves exist on the Sanjiang Plain, and three of them have been listed as wetlands of international importance to water bird conservation by the Ramsar Convention Bureau. The wetlands of Sanjiang Plain are noteworthy for its rich biodiversity, but they continue to decline in area and deteriorate in quality currently. The main threats or constrains, immediate cause, root cause and required response are analyzed in this paper, and the four aspects opinion such as improvement of watershed management, enhancement of protection and restoration of habitats and biodiversity, alternative livelihoods of rural residents living in and near natural wetland reserve, and reinforcement of capacity building of natural reserves are brought forward as the effective measures for the Sanjiang Plain wetland protection.  相似文献

The non-timber forest products (NTFPs) sector in Nepal is being promoted with the concept of sustainable development as articulated by the Convention on Biological Diversity (CBD). Traditionally, people have been dependent on NTFPs for subsistence; however, international trade is growing. To promote this sector, Nepal adopted the 2004 Herbs and NTFP Development Policy. Our goal is to assess the effectiveness of the policy along with the other forestry and natural resource policies in Nepal concerning the conservation and use of NTFPs. We conducted open-ended semi-structured interviews with 28 key informants in summer 2006 in Nepal and collected relevant documents and publications. Qualitative analyses of data yielded important issues that should be addressed to promote the sector as envisioned by the Government. The most important is the need for inventory and research on NTFP species in widespread use. There are some issues regarding species banned under various other National Acts; the lack of marketing information and capacity building; administrative barriers; royalty rates; and illegal harvesting. The most important immediate need is the development of an NTFP Strategy and Action Plan. Our findings should help further implement the policy and promote the sector along the stated mission of conservation and sustainable development.  相似文献

Discussion of the role of non-timber forest products (NTFPs) in efforts to reconcile the objectives of forest conservation and rural development has often been hampered by limited understanding of the complexity of the factors that affect the contribution of NTFPs to local livelihoods. By drawing upon two case studies where NTFPs play an important role - the municipality of Lepaterique in Honduras and Palawan Island in the Philippines - this study emphasizes that an ideal extractive system should be based on a mix of products to enable sustainable harvesting throughout the year. The study also demonstrates that considerable attention needs to be paid to the socio-cultural heterogeneity of resource users, and to the value chain structure, access and control over resources and political transparency that affect the opportunities for local people to benefit from NTFP extraction.  相似文献

This review describes the non-timber forest products (NTFPs) used for different aspects of beauty-care in Bangladesh on the basis of extensive literature survey. The diverse plant species, including used parts and using patterns for hair care, facial treatments and body care, were summarized in 13 tables. This paper accumulate the scattered knowledge regarding the use of plants in beauty-care in Bangladesh, to draw the extent of use of NTFPs in health care and to record the knowledge for assessing the possibilities of further implementation in herbal cosmetics industries. The structured knowledge can be used in policy making process for sustainable management of these valuable NTFPs leading to the conservation of the country's biological diversity. It is suggested that intensive field level research is necessary for securing sustainability of NTFPs.  相似文献

There is new and increasing emphasis on the contribution of non-timber forest products (NTFPs) to improving the livelihoods of rural communities and therefore the need for sustainable management of forest ecosystems of the Miombo woodlands to ensure the continued availability of these NTFPs. This paper examines and reviews some of the work that has been done in the Miombo ecoregion on the ecology, utilisation and management of the Miombo woodlands. The review points to the richness of the Miombo regions' plant species, with an estimated 8 500 species of higher plants, of which over 54% are endemic. The review also highlights the response of the Miombo ecosystem to fire and other anthropogenic processes and the lack of wide-scale adoption or implementation of the major research findings. The review shows that there is a wide range of NTFPs that significantly contribute to the total household income in forest areas and to the national economies through provision of opportunities for small-scale trade especially in the rural areas. However, there is a concern that commercialisation usually results in overexploitation of the resource by the outsiders who become the major players. It is suggested from the review that the lack of capacity by national institutions to manage Miombo woodland resources could be addressed by using participatory approaches to natural resource management. It is also proposed that for sustainable use and management of NTFPs in the Miombo region, research should focus on issues that specifically address NTFPs. In order to facilitate commercialisation and benefit the economically weak, policies that incorporate postharvesting technical assistance and access to information on markets, technology and microcredit should be developed and promoted.  相似文献

There are few observations on the role of non-timber forest products (NTFPs) in shifting from subsistence to commercial plantation-dominated systems with long-term monitoring, despite interests in NTFPs for sustainable development and livelihood dependence. During 1998–2004, we conducted an annual survey of households in the two villages, Baka and Daka, which represent different stages in the shift from a subsistence agroecosystem to a rubber plantation-dominated system in Xishuangbanna, southwestern China. Significant negative correlations were observed between gross income and dependence on NTFPs-generated income in both Baka and Daka villages (P = 0.029 in Baka and P = 0.028 in Daka), which is supporting evidence that poorer households derive greater benefits from NTFPs than do wealthy households. When the rubber price dropped during 1998–2001, the NTFPs income of Baka increased greatly from US$59.10 to US$145 per household, or from 6.4% to 26.6% of household gross income. In contrast, in Daka village, NTFPs income increased by insignificant amounts of US$1.6 per household in 1998 to US$23.8 in 2001, but this was compensated by an increase in income from off-farm work of US$11 to US$147 (an increase from 1.8% to 16.2% of gross income per household) from 1998 to 2001 in Daka. NTFPs retained important roles both in alleviating risk associated with monoculture price fluctuations and in generating income for relatively poor people.  相似文献

Community dependence on forest resources for diverse needs has high implications for long term management of forests. Sustainable extraction of non-timber forest products (NTFPs) is considered best feasible strategy for forest conservation in biodiversity rich areas. This paper examines the heterogeneity of NTFPs use by tribal communities in northeast India, a global hot spot by examining diversity of NTFPs at-large, its consumption pattern, and contribution to rural income and forest revenue. A total of 343 NTFPs recorded used for diverse purposes by tribal communities. When species choice grouped as per use category, utilization for medicinal (163 species), edible fruits (75 species) and vegetables (65 species) purposes was reasonably high. Community dependence on forest resources was 100% for firewood and house construction material. 76 plant species were sold in three major local markets while an additional 22 species traded at commercial scale mainly outside the state. NTFPs contributed 19-32% of total household income for different tribal communities, which was significant. Illicium griffithii, Rubia cordifolia, Oroxylum indicum, Swertia chirayita, Litsea sebifera, Taxus wallichiana, Valeriana jatamansii, Thalictrum foliolosum, Picrorhiza kurrooa, Everniastrum cirrhatum, Cordyceps sinensis, Aconitum fletcherianum, Nardostachys jatamansi, Picrorhiza kurrooa, Gymnadenia orchidis, Calamus, Quercus and Pinus roxbughii were important commercial species. NTFPs also generated substantial revenue to the State government, though it is falling year after year, which is alarming. To meet community livelihoods, income and forest revenue from NTFPs, it desires a thorough management plan and policy guidelines for these resources from all line departments. The knowledge on diversity, its consumption pattern, and contribution to rural income and forest revenue may enable planners to accurately plan sustainable management of NTFP resources and community development in near future.  相似文献

We identified the major non-timber forest products (NTFPs), their contributions to household incomes, and the determinants influenc-ing engagement of households in using NTFPs in the Bonga forest area of Gimbo and Decha Districts of Kaffa Zone, southwest Ethiopia. Six Kebeles (the lowest administrative unit in Ethiopia) were sampled from two Districts and 150 households were randomly sampled using propor-tional-to-size techniques based on the number of farm households in each Kebele. Secondary data were collected from and focus group discussions were conducted with selected individuals. The farmers diversified liveli-hood activities such as crop and livestock production, collection of NTFPs and off-farm activities. NTFPs played a significant role in household incomes. The contribution from the major NTFPs (forest coffee, honey and spices) accounted for 47% of annual household in-come. The role of NTFPs was influenced by a number of factors. Vari-ables including being native to the area (+), total land holding (+), pos-session of livestock (+) and access to extension (+) significantly affected forest coffee production. Age of household head (-), land holding (+) and distance of the market from the residence (-) significantly affected honey production. Size of landholding (+), distance to market (-) and distance of the forest from the residence (-) were significant variables determining the NTFP incomes derived by the households. Attention is needed in the design of policies and strategies for the well-being of households to the contribution of NTFPs to local incomes and the variables that affect the collection of NTFPs must be considered.  相似文献

Academic scholarship and development paradigms promote non-timber forest products (NTFPs) as potential options to link environmental conservation with sustainable economic development objectives for rural communities worldwide. The açaí berry (Euterpe oleracea) is a native palm found in forest ecosystems of northern Brazil and historically extracted and sold in regional markets. Recent increases in national and international açaí demand have resulted in dramatic price increases. Management decisions on a local producer level reflect trends not typically associated with traditional NTFPs as future production and income expectations increase. This case study draws on research conducted in peri-urban communities in close proximity to Belém, Brazil. The work draws links between recent açaí intensification trends in upland areas and information pathways that are contributing to this pattern. This paper argues that external information sources regarding land use choices are prioritized over local knowledge and market indicators which previously have been described as drivers for intensification processes of NTFPs. This qualitative analysis highlights the power structures that influence information sharing and in turn, land use choices on a community level. The results of this analysis are important for NTFP intervention initiatives focused on risk management for smallholders. Finally, this study is a useful complement for ecological studies currently being conducted on intensification processes of non-timber forest products.  相似文献

In recent years, worldwide socioeconomic, ecological, and cultural changes have led to a paradigm shift in forestry and forest management. Some years ago, most forest enterprises exclusively focused on wood production, whereas today, forest management is expected to be multifunctional and economically as well as socially and ecologically sustainable [Harrison, S., Herbohn, J., Niskanen, A., 2002. Non-industrial, smallholder, small-scale and family forestry: what's in a name? Small-scale Forest Economics. Management and Policy 1 (1), 1–11; Schmithuesen, F., 2004. Forest policy developments in changing societies — political trends and challenges to research. Towards the sustainable use of Europe's forests: Forest ecosystems and landscape research: Joensuu: European Forest Institute, Proc., vol. 49, pp. 87–99]. In this context, non-timber forest products (NTFPs) such as forest honey, mushrooms, or berries could gain importance as an additional source of income for the forestry sector. To assess the market potential of NTFPs in Switzerland, two corresponding surveys were conducted. A consumer survey (N = 897) conducted in six cities in Switzerland investigated the purchase of Swiss NTFPs, consumer preferences, and demand potentials. An additional survey of sellers of NTFPs (N = 105) looked at these aspects from a complementary perspective. The results showed that there is a high esteem and considerable demand potential for such products among urban consumers. Food products were mentioned most frequently. Both consumers and sellers considered quality and environmental friendliness the most important attributes of NTFPs. Structural and organizational innovations and considerable marketing efforts and sales promotion would be required to expand the market for Swiss NTFP, however. Our results indicate that certification of the products' origin, environmental performance, and quality could support such efforts and that recreational and ecological forest services have a synergetic potential for the marketing of NTFPs.  相似文献

Uncontrolled harvesting of non-timber forest products (NTFPs) poses a serious risk of extermination to several of these species in Nigeria. Yet, there is a paucity of information on the distribution, population status and sustainable management of NTFPs in most of the tropical lowland rainforests. We, therefore, assessed the population, distribution and threats to sustainable management of NTFPs within the tropical lowland rainforests of Omo and Shasha Forest Reserves, south western Nigeria. Data were obtained through inventory surveys on five top priority species including: bush mango (Irvingia gabonensis (Aubry-Lecomte ex O’Rorke) Baill), African walnut (Tetracarpidium conophorum (Mull. Arg.) Hutch. & Dalziel syn. Plukenetia conophora), chew-stick (Massularia acuminata (G. Don) Bullock), fever bark (Annickia chlorantha Setten & P.J.Maas syn. Enantia chloranta) and bush pepper (Piper guineense Schumach. & Thonn.). Purposive and stratified random sampling techniques were used for the inventory. Each forest reserve was stratified into three, viz: less disturbed natural forest (for areas that have been rested for at least ten years), recently disturbed natural forest (for areas that have suffered one form of human perturba- tion or the other in the last five years), and plantation forest (for areas carrying forest plantation). Data were collected from eighteen 10m×500m belt transects located in the above strata. The species were gener- ally fewer in both plantation and recently disturbed natural forest than the less disturbed natural forest, suggesting that forest disturbances (habitat modification) for other uses may have an effect on the occurrence and densities of the NTFPs. Exceptions to this trend were found for P. guineense and T. conophorum, which were fairly common in both planta-tion and recently disturbed natural forest. Among three tree NTFP species (i.e. I. gabonensis, M. acuminata and A. chlorantha), only I. gabonensis showed a significant difference in overall DBH size classes for both reserves (t=-2.404; df =21; p=0.026). Three tree NTFP species in both reserves further showed differences from the regular patterns of distribution of trees. The fairly regular reverse J-shaped size class distribution observed for M. acuminata in the study sites, however, suggests a recuperating population. In general, destructive harvesting of species, logging operations, low population size, narrow distribution ranges and habitat degradation are the major threats to the population of NTFPs in the study area. The implications of our findings for sustainable management of NTFPs in the study area are discussed and recommendations are made for a feasible approach towards enhancing the status of the species.  相似文献

Abstract

Summary Non-timber forest products (NTFPs) have emerged as a complex set of issues reflecting changes in society and how natural resources are regarded. These issues range from the sustainability of forest management practices to the relationship of diverse cultures and communities to public lands and their resources. Research and its relationship to this set of issues is a relatively unknown aspect of NTFPs.

This paper reports on early NTFP research by scientists in the USDA Forest Service's Pacific Northwest Research Station. It characterizes efforts over approximately five years and identifies their key elements. It also discusses the role research has and could play in addressing the problems and questions associated with NTFPs and sustainable forestry .  相似文献

One of the features of the forest dwellers in the Zagros region of Iran is their dependence on non-timber forest products (NTFPs). These products can play an important role in the livelihood of households located in the forest. The present study aims to determine the most important sources of forest dwellers’ incomes in the northern Zagros in terms of three income groups (lower, middle, and higher), to assess how changes in income are related to types of NTFPs harvested, and to investigate the most significant socio-economic factors determining absolute and relative household revenue from NTFPs. Income in higher- and middle-income groups come predominantly from border trade between Iran and Iraq, comprising 50 and 44 % of relative income, respectively. The main source of income for the lower-income group is remittance and government interest (such as cash subsidies), comprising 31 % of total household annual income. The relative income from NTFPs depends on the income group, varying between 10 and 21 %. Relative income from NTFPs (such as oak acorns, firewood, Gazoo, and Mazooj) for lower-income households is significantly higher than in middle- and higher-income households (p < 0.05). Feed used for grazing livestock in the forest is the most important type of NTFPs in this area, and its benefit in the higher-income group is significantly higher than that for groups with middle and lower income. A similar result is achieved for tree fodder. Relative income from the NTFPs is positively related to number of household members and negatively related to the average education of adult members of the household, the relative income from border trade, and the relative income from agriculture. Our results support our hypothesis that if there is access to other sources of income for forest dwellers, their dependence on forests would be reduced.  相似文献

Ever since their emergence on this planet,human beings have depended on forest resources for their requirements,ranging from food,fuel to shelter.Sustainable extraction of forest resources has been promoted by conservationists and development agencies as a feasible strategy for forest dwellers,which does not diminish the resource base.Yet surveys of actual resource use suggest that for poorer resource-dependent communities without access to markets,non-timber forest products (NTFPs) can only act as a safetynet and a supplementary income source.In southern Meghalaya of India,NTFPs and medicinal and aromatic plants (MAPs) have become an important source of cash and subsistence income for poor people living in or near forests.People in this region have traditionally been collecting different forest products from private forests as well as community conserved forests.The study reveals that NTFPs contribute significantly towards the annual cash income of the local population.The contribution of NTFPs to their income was highest in the case of poor families (9.89%),followed by middle income families (3.34%) and the least for the higher income families (1.34%).Our household survey revealed that 100% of the population is directly or indirectly dependent on NTFPs.Household response indicates diversity in both the types and uses of products collected.  相似文献

A number of factors persist to constrain the non-timber forest products (NTFPs) market and, by extension, its potential to contribute meaningfully to livelihood development and poverty reduction objectives. To better utilise the potential of NTFPs, it is important to have a better understanding of the key factors governing the success and failure of NTFPs trade. This paper reports on the market constraints and socio-economic factors that influence trade in five top-priority NTFPs within the tropical lowland rainforests of south-west Nigeria. The NTFPs investigated were bush mango (Irvingia gabonensis), African walnut (Plukenetia conophora), chew-stick (Massularia acuminata), fever bark (Annickia chlorantha) and bush pepper (Piper guineense). Field data were collected in 10 villages located within and around Omo and Shasha forest reserves using a household questionnaire survey. The results showed that seasonality, poor transport, lack of storage facilities and market information were the four main constraints influencing marketing and trade in the NTFPs. In addition, the level of education, gender (sex), household income, ethnicity, distance to the market and access to roads significantly influenced market knowledge and information among households involved in the trade of NTFPs. There is need to improve on the limited source of NTFPs information, enhance skills for product transformation, build innovative storage facilities, and develop the process of domestication and integration in traditional land-use systems.  相似文献
