A large section of the population (70%) of Uttarakhand largely depends upon agricultural based activities for their livelihood. Rural community of the mountains has developed several indigenous and traditional methods of farming to conserve the crop diversity and rejoice agrodiversity with religious and cultural vehemence. Traditional food items are prepared during occasion, festivals, weddings, and other religious rituals from diversified agrodiversity are a mean to maintain agrodiversity in the agriculture system. Agrodiversity is an insurance against disease and extreme climatic fluctuations, as a coping mechanism in times of scarcity, as a means to enhance overall productivity of farms, as a source of critical nutrition and medicine in the Himalayan region. The different traditional system of agriculture and indigenous method of maintaining soil fertility, socio-cultural and religious rituals has saved many crops that are under threatened category. But all these system and practices are ignored nauseatingly in hill agriculture policy, where more emphasis was given for plain areas. Less emphasis is being put on local systems that rely on existing natural, human, and social assets such as biodiversity, traditional knowledge, and social capital underpinning collective action to ensure food security. Of late, development planners have realized the importance of appropriate technologies and therefore have stressed the need for on-site training, and capacity building of user groups in rural areas of the region. Rural technology demonstration and training center have been supposed as a means disseminating technologies enabling improvement in the yield potential of farms, income generation from off-farm activities, and conservation and efficient use of natural resources. There is a strong need to bring desirable changes in the agricultural policy, research, and development in reference to mountainous regions. The present paper describe present scenario of agriculture, traditional, and socio-cultural practices of retaining soil fertility and agrodiversity, policy dimensions, and strategies for management of the Himalayan agroecosystems. 相似文献

Elderly women of a particular socioecological system are considered to be “living encyclopedias” in biocultural knowledge systems. These women play a pivotal role in retaining and passing on biodiversity-related traditional knowledge to the next generations. Unfortunately the fast changing sociocultural values and the impact of modernity have rendered their knowledge somewhat less valuable and they are being treated as “cultural refugia.” Our study on the importance of these women in the conservation of indigenous biodiversity was conducted in 14 randomly selected villages dominated by the Adi tribe of East Siang District, Arunachal Pradesh (northeast India). Data were collected from 531 women (381 elderly and 150 young to middle aged) during 2003–2008 using conventional social science methods and participatory rural appraisal. One innovative method, namely “recipe contest,” was devised to mobilize Adi women of each village in order to energies them and explore their knowledge relating to traditional foods, ethnomedicines, and conservation of indigenous biodiversity. Results indicated that 55 plant species are being used by elderly Adi women in their food systems, while 34 plant species are integral parts of ethnomedicinal practices. These women identified different plant species found under multistory canopies of community forests. Elderly women were particularly skilled in preparing traditional foods including beverages and held significantly greater knowledge of indigenous plants than younger women. Lifelong experiences and cultural diversity were found to influence the significance of biodiversity use and conservation. The conservation of biodiversity occurs in three different habitats: jhum lands (shifting cultivation), Morang forest (community managed forests), and home gardens. The knowledge and practice of elderly women about habitats and multistory vegetations, regenerative techniques, selective harvesting, and cultivation practices contribute significantly to food and livelihood security while sustaining an array of threatened plant species. Basically, knowledge of elderly women on using biodiversity in food and medicinal systems was found in three categories namely: “individual,” “community,” and “refined.” We identified a need to develop holistic policies to recognize and integrate knowledge and practices of elderly women with local level of planning on sustainable conservation of biodiversity as well as community-based adaptations. 相似文献

Effects of sheep and goat grazing on the species diversity in the alpine meadows of Western Himalaya 总被引:3,自引:0,他引:3
This paper deals with effects of sheep and goat grazing on plant species diversity, species richness and species composition in two important conservation areas of the Western Himalaya; the Valley of Flowers (VOF) National Park and the Great Himalayan National Park (GHNP). The VOF is a completely Protected Area as it is devoid of livestock grazing whereas, 20,000 sheep and goats annually graze in GHNP. Both the National Parks possess sub-alpine and alpine vegetation that is distributed in 13 major habitat types. Present investigations indicate that all the habitat types in VOF are higher in plant species diversity and richness compared to habitat types in GHNP. Similarly, all three eco-climatic zones in VOF are higher in species diversity and richness compared to GHNP. Species diversity also decreases with increasing altitude in both the National Parks. The findings of this study are discussed in the light of the management and conservation of alpine meadows of the Western Himalayas. 相似文献

Sacred groves are well recognized in the world in terms of biodiversity conservation. The present study was conducted in the Nakuleshwar sacred grove, in the valley of Thal kedar hill in the Kumaon region of Pithoragarh district in Indian Himalaya, in appreciation of its role in biodiversity conservation. The study aimed at the documentation and inventory of the sacred grove, its phytodiversity, threats and conservation in the Himalayan region, and to achieve this, systematic field surveys were conducted during 2007?C2010 covering all four seasons. A total of 83 species from 71 genera and 50 families were identified, of which 43 species are flowering plants, including 7 trees, 7 shrubs, 4 climbers and 25 herbs, and 40 species are non-flowering plants of which lichens are represented by 12 species from 8 genera, bryophytes 6 species from 5 genera, and pteridophytes 7 species from 9 genera, while gymnosperms are represented by a single species. Acer oblongum, Cinnamomum tamala, Cedrus deodara, Coriaria nepalensis act as keystone species in the grove. Ophiopogon inermis is a common herb during the rainy season while Goodyera hemsleyana (Orchid) is a new distribution record for the western Himalaya. A total of 43 species from 38 genera are used ethnobotanically by local people for various ailments. Mahonia nepaulensis, Asparagus adscendens, Thalictrum foliolosum, Cinnamomum tamala and Berberis asiatica are highly exploited species and need to be conserved. Climatic conditions of the grove are moderate and the floristic patch of the grove is completely different from the plant diversity of the surrounding area and matches with the diversified floral wealth of comparatively higher altitudes. Due to anthropogenic pressure, this grove is facing new threats of degradation, hence needing special attention. 相似文献

The study of the interrelationship between ethnomedicinal knowledge and socio-cultural values needs to be studied mainly for the simple reason that culture is not only the ethical imperative for development, it is also the condition of its sustainability; for their exists a symbiotic relationship between habitats and cultures. The traditional communities around Binsar Wildlife Sanctuary of Uttarakhand state in India have a rich local health care tradition, which has been in practice for the past hundreds of years. The present study documents the Ethnomedicinal uses of 54 medicinal and aromatic plants (MAPs) along with their botanical and vernacular names, family, habit, habitat, threat status, collection season, purpose of collection, quantity, conservation practices, market potential and part(s) used in traditional health care system. The documented species belonging to 38 families have been used to cure more than 47 different kinds of ailments. These MAPs collected from the wild in a particular season and used as per the method prescribed by traditional herbal healers (Vaidyas) that provide effective results. Perception of local people during field trips based on socio-demographic characters showed them to prefer herbal system of treatments and they understood the status of traditional health care systems in the region. The study reveals that approximately 70 % population of the study area depend on herbal systems of treatments and preferred to visit Vaidyas for curing a variety of ailments because the traditional system of medicine is one of the most important prevailing systems in the region where modern health care facilities are rare or in very poor conditions. The organic cultivation practices of selected MAPs were demonstrated to rural inhabitants through capacity building training program and participatory action research framework approaches for sustainability and enhancement of livelihood security. A series of workshops and village level meetings on traditional health care systems were organized and forming/registered a strong association of Vaidyas for making their traditional system of health care more practical and effective. The study emphasizes the potentials of the ethnomedicinal research, conservation practices, socio-cultural and religious ethics for promoting traditional plants based treatments and also the need to document the indigenous knowledge for scientific validation before its industrial application. 相似文献

The paper describes the design and implementation of a plant biodiversity conservation program that was developed under funding and time constraints for diverse ecological, social, and institutional environments. The biodiversity program for alpine meadows and pastures located in the Swiss Canton of the Grisons is used as an example. The design of the sustainable program relied on existing legislation, accounted for limited ecological knowledge and expertise, and considered biodiversity as a common-pool resource. The trend to intensified cultivation of restricted areas required fast action, while the sustainability of the program design had to take into account institutional diversity. Fifteen habitats and plant communities worth conserving were known, and 57 plant species were identified as indicator species for establishing an inventory and for monitoring purposes. A small subset of 16 well known plant species was presented to the farming communities. They were invited to notify the areas in which they observed the presence of these plants. In different regions of the Canton a total number of 39 paraecologists were trained to inspect the areas notified by farmers and to recommend possible incorporation into the Cantonal inventory. This was done once the farmers signed a contract in which they agreed to follow adequate management practices. The farmers received subsidies to compensate for their losses. Communal authorities controlled the fertilizer input and cutting dates, while the paraecologists were trained to monitor plant biodiversity. The program started in 1992 and the initial phase of the inventory was terminated in 1996. At the beginning of 1996, an inventory of 2617.19 ha, most of which are meadows, was taken and managed according to the rules specified in the contract. The program was considered successful because (i) of the size of the area in the inventory, (ii) about 30%of the farmers participated, and (iii) farmers started cultivating previously abandoned farmland. 相似文献

Worldwide there is a declining trend in natural fish catch (FAO, The state of world fisheries and aquaculture. , 2002) and Bangladesh is no exception. The vast inland fisheries of Bangladesh have been declining over the years, largely a result
of human alteration of the aquatic habitats arising from human interventions in the floodplain systems such as the establishment
of water control structures which favor agricultural production but reduce fish habitats. It can be assumed that conventional
management measures are not adequate to conserve natural fisheries and exploring alternative knowledge systems to complement
existing management is warranted. This paper focuses on local ecological knowledge and several other local practices held
by fishers engaging directly with floodplain ecosystems. These knowledge systems and practices may be valuable tools for understanding
ecosystems processes and related changes and developing local level responses to avert negative consequences of such changes.
This may help in devising alternatives to ecosystem management and the conservation of floodplain fish habitats of Bangladesh
and elsewhere in the world. This study was conducted in a natural depression (locally called beel) and its surrounding floodplain system located in north central Bangladesh which has become highly degraded. The results
of the study indicate that the fishers and local users of the floodplain ecosystems are rich in local ecological knowledge
concerning the hydrology of the floodplains and small lakes, the habitat preferences of fish, the role of agricultural crops
on fish habitats, and the impact of habitat human interventions in aquatic ecosystems. Given the apparent inadequacy of the
present management regime, this article argues for an inclusion of local knowledge and practices into habitat management as
a more holistic approach to floodplain habitat restoration and conservation that encourages multi-level cooperation and which
builds on diversified knowledge systems. 相似文献

The diversity of plant resources in the Brazilian semi-arid region is being compromised by practices related to agriculture,
pastures, and forest harvesting, especially in areas containing Caatinga vegetation (xeric shrublands and thorn forests).
The impact of these practices constitutes a series of complex factors involving local issues, creating a need for further
scientific studies on the social-environmental dynamics of natural resource use. Through participatory methods, the present
study analyzed people’s representations about local environmental change processes in the Brazilian semi-arid region, taking
into consideration local production systems, natural resources, and their importance. Environmental historical graphs were
developed with nine local families to analyze landscape changes with regard to cultivated areas and pastures, and their relationship
with the availability of native vegetation. Punctuation exercises were performed to observe the importance of each unit that
supplied native and cultivated resources. The availability of native resources in the environment is subject to stability,
as observed by a majority of the local families. The role of the production units (crops and pastures) was emphasized by most
families in the study, especially because of the need for products for subsistence needs and income generation. The current
decline of such practices is a consequence of an exodus of field workers and also relates to the conservation of native species
that otherwise would have been deforested in favor of agricultural practices. 相似文献

This article compares a range of initiatives aimed at involving people in the management of forest resources in Nepal and
India. In Nepal, we focus on three categories of state-initiated programs: community forestry, the parks’ buffer zone program,
and leasehold forestry. In the southern Indian state of Karnataka, we study the state-initiated Joint Forest Planning and
Management program along with older institutions of leaf manure forests (Soppina betta) and historical sacred forests (Kans). We conclude that state-initiated approaches to involving communities have been limited, at best, promote standardized and
relatively inflexible management practices, and lead to partial improvement in biodiversity and people’s livelihoods. When
management is initiated and owned by the community, as in the case of sacred groves in India, and when other conditions are
appropriate, communities can have the opportunity to demonstrate their capacity for putting effective and adaptive conservation
practices in place. 相似文献

The East Usambara Mountains, recognized as one of the 25 most important biodiversity hot spots in the world, have a high degree
of species diversity and endemism that is threatened by increasing human pressure on resources. Traditional slash and burn
cultivation in the area is no longer sustainable. However, it is possible to maintain land productivity, decrease land degradation,
and improve rural people’s livelihood by ameliorating cultivation methods. Improved agroforestry seems to be a very convincing
and suitable method for buffer zones of conservation areas. Farmers could receive a reasonable net income from their farm
with little investment in terms of time, capital, and labor. By increasing the diversity and production of already existing
cultivations, the pressure on natural forests can be diminished. The present study shows a significant gap between traditional
cultivation methods and improved agroforestry systems in socio-economic terms. Improved agroforestry systems provide approximately
double income per capita in comparison to traditional methods. More intensified cash crop cultivation in the highlands of
the East Usambara also results in double income compared to that in the lowlands. However, people are sensitive to risks of
changing farming practices. Encouraging farmers to apply better land management and practice sustainable cultivation of cash
crops in combination with multipurpose trees would be relevant in improving their economic situation in the relatively short
term. The markets of most cash crops are already available. Improved agroforestry methods could ameliorate the living conditions
of the local population and protect the natural reserves from human disturbance. 相似文献

Environmental, biological, socio-cultural and economic variations in the Himalayas have led to the evolution of diverse and unique traditional agroecosystems, crop species, and livestock, which help the traditional mountain farming societies to sustain themselves. During the recent past, as a result of rapid changes in land use caused by socio-cultural and economic changes and various environmental perturbations, the agrobiodiversity of the Central Himalayan agroecosystems has changed steadily. A recent survey conducted in 150 different villages located along an elevated transect of the Alaknanda catchment of the Central Himalaya revealed that over a period of two decades (1970–74 and 1990–94) the cultivated area under many traditional crops had declined significantly. A micro-level study carried out in 30 villages revealed that a series of changes had occurred in land use practices over a period of 25–30 years.The loss of agrobiodiversity and the changing socio-cultural and economic dimensions and their impacts on the sustainability of Himalayan agroecosystems are emerging as major causes of concern at local/regional/national scale, and appropriate options to meet these challenges are discussed in this paper. 相似文献

The current study documented local utilization of Cyperus papyrus L. (papyrus), harvesting patterns, threats, and local management practices among the Endorois community living around Loboi swamp (Kenya). Papyrus is a highly productive freshwater macrophyte that is widely utilized throughout tropical Africa. However, increased human population and poverty, has led to over exploitation and conversion of papyrus wetlands to agricultural fields. Nonetheless, users of papyrus hold important local ecological knowledge (LEK) and practices. We show that Endorois practices on papyrus uses are compatible with the management priorities of the swamp and a wider conservation framework using data obtained from three focus group discussions (FGD), interviews of 34 households and 15 key informants. The study revealed that papyrus support local livelihood notably as a source of income (papyrus mats are sold), cattle fodder, roofing materials (shelter), and cooking fuel. The study further revealed important LEK relating to harvesting patterns, recovery after harvesting and traditional management practices. Correlation and principal component analyses showed that experienced old harvesters (EXPERT) avoided harvesting repeatedly at the same location (REVISIT), thereby allowing recovery of papyrus when compared to younger harvesters (r = 0.63, p < 0.01). However, over 70% of harvesters predicted a decrease in papyrus coverage in the future due to the current diversion of water from the swamp, and frequent droughts, despite the instituted traditional management strategies (e.g. rotational harvesting) to curb overharvesting. The study concluded that the documentation of site-scale papyrus users' profile, LEK, and traditional practices are vital for the conservation and management of Loboi swamp. 相似文献

Local Biodiversity Action Plans are the preferred policy mechanism for setting and delivering local biodiversity targets in the UK. This paper reviews the kind of knowledge conservation scientists envisage being used to identify and set local targets, and explores the means of incorporating local knowledge into this process. We use a case study of a Wildlife Enhancement Scheme (WES) on the Pevensey Levels, East Sussex, to reveal the understandings that local farmers and residents have of the nature conservation goals and practices associated with the scheme. Drawing on the findings of in-depth discussion groups, we show how farmers challenge both the monopoly of knowledge conservationists profess about nature, and the enlistment of farmers on the scheme as «technicians», motivated solely by financial rewards, rather than as knowledgeable experts who also have emotional attachments and ethical values for nature. Local people use their knowledge of both local farmers, and the industry in general, to challenge the assumption that farmers can be trusted with delivering nature conservation goals. In the absence of a commitment by central government to agree widely-held environmental standards, and a more democratic process of making judgements about what local nature is worth conserving, local residents challenge existing processes designed to conserve nature that are driven by the knowledge and practices of official experts alone. The findings of the study suggest that a widening of the knowledge base on which the goals and practices of nature conservation are founded, and a more deliberative process of making decisions about what nature is important locally, will secure and strengthen public support for local biodiversity action plans.1998 Academic Press 相似文献

High demand for outdoor recreation and increasing diversity in outdoor recreation participants have imposed a great challenge
on the National Park Service (NPS), which is tasked with the mission to provide open access for quality outdoor recreation
and maintain the ecological integrity of the park system. In addition to management practices of education and restrictions,
building a sense of natural resource stewardship among visitors may also facilitate the NPS ability to react to this challenge.
The purpose of our study is to suggest a segmentation approach that is built on the social marketing framework and aimed at
influencing visitor behaviors to support conservation. Attitude toward natural resource management, an indicator of natural
resource stewardship, is used as the basis for segmenting park visitors. This segmentation approach is examined based on a
survey of 987 visitors to the Padre Island National Seashore (PAIS) in Texas in 2003. Results of the K-means cluster analysis
identify three visitor segments: Conservation-Oriented, Development-Oriented, and Status Quo visitors. This segmentation solution
is verified using respondents’ socio-demographic backgrounds, use patterns, experience preferences, and attitudes toward a
proposed regulation. Suggestions are provided to better target the three visitor segments and facilitate a sense of natural
resource stewardship among them. 相似文献

Globally, cultural values of natural resources are increasingly recognised as important for local natural resource management and conservation in and beyond parks. The tendency has been to focus on the direct-use rather than the cultural values and importance of natural resources. The cultural values underlying natural resources (directly or indirectly used) and various natural resource-based activities, and the implications for conservation, remain little explored. Drawing from household surveys, in-depth qualitative interviews, observations and secondary data, we explore the cultural significance of natural resources and different land-use practices among the San people bordering Kgalagadi Transfrontier Park in South Africa. Our findings illustrate that though cultural values are inextricably linked to resource use, they are not recognised by all community members. Further, cultural values arise from a diverse and sometimes conflicting array of values that punctuate individuals' lifestyles. A better understanding of context-specific cultural settings and the linkages between the cultural and material dimensions of resource use can lead to the development of interventions that can ensure effective conservation of both natural resources and culture. 相似文献

The cerco-fixo is an artisanal fishing trap widely used by traditional communities in the estuarine region of the southern coast of the state of São Paulo, Brazil. The primary goal of the study was to investigate, through ethnobotanical and ecological approaches, the use of plant species by traditional fishermen to build the cerco-fixo at Cardoso Island State Park and Cananéia Island. Ethnobotanical data were collected through interviews, direct observation, plant collection and identification, and document analysis. An ecological evaluation was also done comparing five 20 × 20 m plots in a managed area to five 20 × 20m plots in an unmanaged area, both within arboreal sandy soil vegetation called restinga arbórea, found within the Brazilian Atlantic Forest domain. This study involved 34 fishermen living at Cardoso and Cananéia Islands. The fishermen know more than 90 Atlantic Forest plant species that can be used to build the cerco-fixo. Tree species from the family Myrtaceae were the most quoted in the interviews. With respect to the ecological evaluation, the cluster analyses showed greater heterogeneity in terms of floristic composition (i.e. greater floristic dissimilarity) within the plots of the managed area. The analyses of diversity showed a slightly higher species richness and slightly lower values for Shannon, Simpson, Hurlbert’s PIE and Evenness indices in the managed area (59 species; H′ = 3.28; 1/D = 10.77; E = 0.80; Hurlbert’s PIE = 0.91) compared to the unmanaged area (54 species; H′ = 3.39; 1/D = 20.21; E = 0.85; Hurlbert’s PIE = 0.95). The Hutcheson’s t test showed no significant difference between both areas’ Shannon diversity indices (t: −1.04; p: 0.30). These results are attributed to the greater dominance of the palm species Euterpe edulis Mart. in the managed area (28.2% of the trees sampled at this area; n = 118), which equals twice the percentage of individuals of the same species found for the unmanaged area (14.6% of the sampled trees; n = 48). We discuss the impact of the fishermen’s harvesting practices in the managed area with an emphasis on three main points: (1) the harvesting practices are likely not contributing to a decrease in diversity in the managed area; (2) the greater heterogeneity in terms of floristic composition found for the managed area may reflect a mosaic pattern created by the opening of small tree-gaps distributed across this area over the course of more than 50 years; (3) the disturbance promoted by the fishermen’s harvesting practices can be compared to natural disturbances of low impact that create mosaic patterns in tropical forests. This study emphasizes the prominence of the human dimension in ecological processes and the importance of considering the perspectives of local people when discussing the conservation of the natural environments in which these people live. 相似文献

The Aquatic Macrophyte Community Index (AMCI) is a multipurpose tool developed to assess the biological quality of aquatic
plant communities in lakes. It can be used to specifically analyze aquatic plant communities or as part of a multimetric system
to assess overall lake quality for regulatory, planning, management, educational, or research purposes. The components of
the index are maximum depth of plant growth; percentage of the littoral zone vegetated; Simpson's diversity index; the relative
frequencies of submersed, sensitive, and exotic species; and taxa number. Each parameter was scaled based on data distributions
from a statewide database, and scaled values were totaled for the AMCI value. AMCI values were grouped and tested by ecoregion
and lake type (natural lakes and impoundments) to define quality on a regional basis. This analysis suggested that aquatic
plant communities are divided into four groups: (1) Northern Lakes and Forests lakes and impoundments, (2) North-Central Hardwood
Forests lakes and impoundments, (3) Southeastern Wisconsin Till Plains lakes, and (4) Southeastern Wisconsin Till Plains impoundments,
Driftless Area Lakes, and Mississippi River Backwater lakes. AMCI values decline from group 1 to group 4 and reflect general
water quality and human use trends in Wisconsin. The upper quartile of AMCI values in any region are the highest quality or
benchmark plant communities. The interquartile range consists of normally impacted communities for the region and the lower
quartile contains severely impacted or degraded plant communities. When AMCI values were applied to case studies, the values
reflected known impacts to the lakes. However, quality criteria cannot be used uncritically, especially in lakes that initially
have low nutrient levels. 相似文献
