Commercial Medicinal Plant Extraction in the Hills of Nepal: Local Management System and Ecological Sustainability 总被引:1,自引:0,他引:1
Helle Overgaard Larsen 《Environmental management》2002,29(1):88-101
This paper presents a case study from Jumla District, Nepal, investigating local management systems and ecological sustainability
of commercial collection of a medicinal plant, spikenard (Nardostachys grandiflora DC, Valerianaceae), growing in alpine meadows. Interviews were undertaken with local collectors, traders, and district forest
office staff, and the dynamics of people–plant interactions are analyzed using the Oakerson model. In all, 110 sample plots
1m square were laid out in three areas with differing collection and grazing pressures for recording of floristic composition
and abundance of spikenard root biomass. Comparisons show significantly more root biomass in uncollected than collected areas
with local management and the interpretation of differences in abundance is discussed. The combination of qualitative and
quantitative investigations can provide a framework for the study of people–plant interactions, and this study can serve as
first step in a compilation of cases to create a more detailed picture of local management systems of Nepali nontimber forest
products in general and commercially collected medicinal and aromatic plants in particular. 相似文献

/ During the last decade, a major initiative for community involvement in the management of state forest lands was started in India in the form of Joint Forest Management (JFM) programs. Despite the progress and positive impacts, the JFM program is still in the experimental phase. Latent conflicts related to caste, class, and gender issues are threatening JFM institutions at the village level. The Forest Department is also facing a number of internal conflicts as it tries to adjust to its new role under JFM. Some thoughtful and creative attempts have been made to resolve these conflicts. However, a much more concerted effort is required along with creation of suitable mechanisms at local, state, and national levels to discuss and resolve present and future conflicts. 相似文献

The paper explores the impact and sustainability of environmental assistance coming to Russia from EU-based public and private foundations, and its implications for environmental governance. Geographically, the study ’encompassed all the assistance projects awarded in 1991–2016 involving beneficiaries from Pskovskaya Oblast’. This region is potentially an important target for EU investments in environmental infrastructure, due to its location by the EU border and high value of natural capital. The study demonstrates how the assumptions offered by the international aid literature (mostly derived from the global South) apply to Russia. We found major limitations to the assumption that co-financing provided by recipients ensures project effectiveness (demonstrating the acceptance of the donor's agenda) or sustainability (providing interest to the maintenance of outputs). Tangible assets are normally co-financed only if the investment was in agenda anyway (and therefore the donor gets only time gains, although this can be a valid purpose too); soft outputs (plans, surveys, policies, etc.) are usually co-financed in-kind, and therefore cannot secure any additional commitment. Likewise, physical infrastructure often ends up mismanaged due to low or no maintenance budgets available, while maintenance of soft outputs is too much dependent on contextual factors beyond the co-finance paradigm. 相似文献

Traditional Land-Use Systems and Patterns of Forest Fragmentation in the Highlands of Chiapas, Mexico 总被引:1,自引:0,他引:1
Ochoa-Gaona S 《Environmental management》2001,27(4):571-586
The influence of slash-and-burn agriculture and tree extraction on the spatial and temporal pattern of forest fragmentation
in two municipalities in the highlands of Chiapas, Mexico was analyzed. The data series were derived from two subsets of satellite
images taken in 1974 and 1996. The analysis was based on area, edge, shape, core area, and neighbor indices. During the 22
years, the dense forest decreased by 8.9%/yr in Huistán and by 8.6%/yr in Chanal, while open/disturbed forest, secondary vegetation,
and developed area increased in both municipalities. The total number of fragments increased by 1.4%/yr and 2.3%/yr in Huistán
and Chanal, respectively. Dense forest showed the highest increase in the number of fragments (6%/yr in Huistán and 12%/yr
in Chanal), while edge length, core area, and number of dense forest core areas decreased. The larger fragments of dense forest
present in 1974 were divided into smaller fragments in 1996; at the same time, they experienced a process of degradation toward
open/disturbed forest and secondary vegetation. Two different fragmentation patterns could be distinguished based on agricultural
or forestry activities. Forest fragmentation did not occur as a continuous process; the pattern and degree of fragmentation
were functions of land tenure, environmental conditions, and productive activities. The prevalence of rather poor soil conditions,
small-holdings, growing human population densities, increasing poverty, and the absence of alternative economic options will
maintain a high rate of deforestation and forest fragmentation in the studied region. 相似文献

Cultural taboos and their sanctionshave helped to check abuse of the environmentat least among the local people. The disregardfor these traditional checks and balancesespecially among Christians has adverselyaffected their enforcement at this time. Theenvironment and culture preservation inAwka-South were investigated. The faithfulobservance of the traditional laws in the studyarea was attributed to the fact that Awka-Southarea had remained occupied by the same peoplefor centuries. The study showed that thepreserved forests and their shrines in Nibotown have largely remained intact. In Nisetown, however, with nine shrines still inexistence, the rules have relaxed a little,mainly because they embraced modernization. Inthis town, the fringes of the forests may beused for farming but no felling of trees wouldbe allowed. The ``god' of the shrine in Obunaguvillage was much revered until the advent ofChristianity. This religion has had an erodingeffect on the taboos, which were put in placeto protect their forests and streams. Theabandonment of traditional cultural practicesis doing harm that goes beyond the abrogationof traditional cultural practices to seriousthreat to natural environmental structures. Thecultures of the different tribes in Nigerianeed to be revisited for evaluation and studiesto enable their integration into modernpractices that will make the environment moresustainable. This will be more productive thanthe unilateral introduction of programs,execution, and maintenance methods that arecompletely new, or in many cases run contraryto the cultural practices of the local peopleand tribes of Nigeria. 相似文献

This paper offers some suggestions on, and encouragement for, how to be better at risk communication in times of agricultural crisis. During the foot and mouth epizootic, the British public, having no precedent to deal with such a rapid and widespread epizootic, no existing rules or conventions, and no social or political consensus, was forced to confront the facts of a perceived "economic disease. Foot and mouth appeared as an economic disease because the major push to eradicate it was motivated exclusively by trade and economic reasons and not because of threats it posed to the lives of human beings and livestock. The British public deferred responsibility to their elected officials for a speedy end to this non-life threatening viral epizootic. The latter, however, did not have a contingency plan in place to tackle such an extensive outbreak. The appeal to an existing policy, i.e., mass eradication, as the exclusive strategy of containment was a difficult pill for the public to swallow well before the end of the 226-day ordeal. Public outcry reflected (in part) serious misgivings about the lack of effective communication of risk-informed decisions between government agents and all concerned. The government's handling of the matter underestimated concerns and values about animal welfare, public trust, and the plight of farmers and rural communities. A general loss of trust by some segments of the public was exacerbated by perceived mismanagement and early fumbles by government agents.Public moral uneasiness during the crisis, while perhaps symbolic of growing discontent with an already fractured relationship with farmed animals and the state of animal farming today, arguably, also reflected deep disappointment in government agents to recognize inherently and conditionally normative assumptions in their argument as well as recognize their narrow conception of risk. Furthermore, broader stakeholder participation was clearly missing from the outset, especially with respect to the issue of vaccination. A greater appreciation for two-way risk communication is suggested for science-based public policy in agriculture, followed by suggestions on how to be more vigilant in the future. 相似文献

Living Amidst Large Wildlife: Livestock and Crop Depredation by Large Mammals in the Interior Villages of Bhadra Tiger Reserve,South India 总被引:7,自引:0,他引:7
Conflict with humans over livestock and crops seriously undermines the conservation prospects of India's large and potentially
dangerous mammals such as the tiger (Panthera tigris) and elephant (Elephas maximus). This study, carried out in Bhadra Tiger Reserve in south India, estimates the extent of material and monetary loss incurred
by resident villagers between 1996 and 1999 in conflicts with large felines and elephants, describes the spatiotemporal patterns
of animal damage, and evaluates the success of compensation schemes that have formed the mainstay of loss-alleviation measures.
Annually each household lost an estimated 12% (0.9 head) of their total holding to large felines, and approximately 11% of
their annual grain production (0.82 tonnes per family) to elephants. Compensations awarded offset only 5% of the livestock
loss and 14% of crop losses and were accompanied by protracted delays in the processing of claims. Although the compensation
scheme has largely failed to achieve its objective of alleviating loss, its implementation requires urgent improvement if
reprisal against large wild mammals is to be minimized. Furthermore, innovative schemes of livestock and crop insurance need
to be tested as alternatives to compensations. 相似文献
