Rural households throughout the Himalayas are regarded as dependent on non-timber forest products (NTFPs), but very few studies
have quantified this dependency. This case study, undertaken in two villages in the Central Himalayan foot hills in Nepal,
documents the absolute and relative importance of commercial NTFPs to rural household economies. Data were collected in a
one-year period and included interviews with 250 households using a semi-structured questionnaire and monthly interviews with
four sub-local NTFP traders, two local traders and two central wholesalers. The conservative estimate of NTFP-derived cash
income showed this to be a cornerstone in poorer household livelihood strategies and thus in poverty prevention. An annual
average of 578 kg of commercial NTFPs was collected in the wild per household, providing poorer households with a cash income
share of 44–78%. Better off households are not NTFP dependent but rely on income from crop production and livestock. Based
on a net marketing margin analysis, showing that harvesters capture a large share of the Indian wholesaler price, it is argued
that there is scope for pursuing NTFP-based strategies for poverty reduction through leasehold forestry and agroforestry.
Both these options are compatible with conserving forest cover and forest corridor functions and may thus present a win–win
scenario for livelihood improvement and conservation. 相似文献

Deforestation studies have attracted considerable attention over the past two decades. Analyses of local deforestation examine
the significance of numerous explanatory variables for the extraction of forest products. This study distinguishes among the
explanatory variables as household-specific and site-specific, and argues for in-depth analysis of household-specific variables.
It examines the role of household size, income, and education on firewood extraction and beedi-making in the Western Ghats
of India, a hotspot of biodiversity. The study documents the incidence of these livelihoods, investigates the interaction
among the three variables, and uses logistic regression models to determine the exact probability for the livelihoods. Two
novel features of the study include analysis of wood and non-wood extraction through a single dataset and determination of
model by the data. The results show high dependency of households on forest-based livelihoods, situations when the probability
of livelihoods changes substantially, and non-parallel trends for household dependency. The study suggests the role of household-specific
variables as the agents of motivation and persistence for forest-based livelihoods and presents a hypothesis about the critical
size of household in forest dependency. The study recommends four measures—harvest of ecosystem services, rise in income,
migration and mobility, and environmental education—to promote sustainable livelihoods. 相似文献

Non-timber forest products (NTFP) represent key sources of cash and subsistence income for millions of rural and indigenous
peoples living in tropical developing countries throughout the world. The current study investigates the use and significance
of NTFP within a sample of Peninsular Malaysia’s Orang Asli (indigenous people). Data collected via household surveys across
three sampling phases reveals that more than 75% of the population is actively engaged in NTFP collection. Household responses
indicate diversity in both the types and uses of products collected. NTFP collection participation, frequency of collection,
and collection reliance are found to be significantly negatively related to village proximity to the market, as well as to
income level relative to the Malaysian poverty line. When collection variables are examined by different product categories,
relationships with market access and income group are variable. Implications for different approaches to forest conservation
and rural development are discussed. 相似文献

The aim of this paper is to disclose livelihood strategy-poverty links and gain a better understanding by developing typologies
of rural households. Based on qualitative and quantitative data, we group households into different typologies and explore
interactions. We identified six main agronomic strategies, four dominant livelihood diversification strategies, and income
quartiles (proxies for poverty) using cluster and principal component factor analysis. We found that nearly 82% of the surveyed
farmers in the study area belong to the bottom income quartiles while about 18% are on the upper quartiles. Households in
the bottom income quartiles engaged in casual off-farm work and cereal-dominated livelihood strategies that tend to pursue
subsistence farming by growing cereals and oil crops. Contrarily, farmers in the upper income quartiles adapted intensive
agronomic strategies by integrating root crops, legumes, and vegetables with livestock. This was largely attributed to access
to key livelihood assets such as land, livestock, education, and institutional support in which the upper quartiles were more
endowed. Improving availability of the key assets for the bottom income quartiles might be a way out of poverty and ensuring
sustainable development. It is crucial to recognize local-level heterogeneities of rural households when targeting development
interventions. 相似文献

This article attempts to explore the nexus between rural households’ environmental dependency, poverty and livelihood strategies. Households’ income from each livelihood activities formed the basis for categorizing households according to livelihood strategies. The principal component analysis, agglomerative hierarchical and the k-means cluster analysis were employed to determine the four livelihood clusters and to assign households to the identified livelihood strategies. Households’ environmental dependency, poverty and asset holding were compared across the strategies, and the determinants of livelihood choice were analyzed using multinomial logit model. The results indicate the existence of marked differences in environmental dependency, rural poverty and asset endowments across the livelihood groups. Household’s total saving, access to credit, production implements, business cost, exposure to agricultural shock determined household’s access to a more remunerative livelihood strategy. Incomes from each livelihood activities for the identified livelihood strategies were analyzed, and their implications were also discussed. 相似文献

Traditional ecological knowledge and local experience of resource management and the usefulness of plant species can make
important contributions to attempts to understand forest ecosystems and to develop effective sustainable management strategies
for them. Therefore, the utilization of tree species by local people, their perceptions of changes in the surrounding forests,
and suggested solutions for associated problems, were studied in the Sissili province of southern Burkina Faso. Information
was collected through a combination of participatory rural appraisals, household interviews, and observational methods. Principal
component analysis was used to analyze the consumptive values of woody species and their respective parts. A total of 82 species
were identified, 90% of them were used for medicinal purposes, 78% for fodder, 73% for food, 67% for house construction, and
58% for wood carving. This suggests that forests play a key role in sustaining the rural livelihood and contributing to poverty
reduction. The various stakeholders perceived that vegetation clearing for cultivation of cash crops (agribusiness) was the
main driver of the change in forest cover. Species reported to be declining in the area included Parkia biglobosa, Pterocarpus erinaceus, Afzelia africana, Bombax costatum, Tamarindus indica, and Diospyros mespiliformis. Thus, a concerted effort should be made to manage the remaining natural forests in the country. Appropriate management strategies
should be developed jointly by the local communities and external support groups to integrate the valuable local knowledge
about forest species with the stakeholders’ suggestions in order to promote sustainable management of the region’s forest
ecosystems. 相似文献

In Ghana, forests provide many products on which the local population subsists. However, these resources are depleting due
to a variety of factors including agricultural expansion and over-exploitation of forest resources. This paper presents an
analysis of the level of local dependence on forest resources and its implications for forest management in Ghana. The paper
also outlines the causes of continuing deforestation in the studied region from the perspective of the local residents and
discusses what role they could play in addressing the problem. The aim is to share more light on the current causes of deforestation
and make suggestions for improved community-based forest management practices that could help to reduce deforestation. Primary
data was collected through personal interviews and focus group discussions with 431 household heads randomly selected from
three Forest Districts in Ghana. The survey showed that income from agriculture constituted 60% of the average total rural
household income. Forest income provided 38% of total household income, and off-farm income 2%. The four most highly ranked
causes of deforestation are poverty-driven agriculture, lack of alternative rural wage employment other than farming, household
population levels, and conflict in traditional land practices. This shows a shift in the view of local people who in the past
were quick to blame logging companies and government policies for deforestation. The majority of the respondents depended
on wild animals like snail, bush meat, wild honey and wild and cultivated vegetables. Given the reasons for deforestation,
much thought needs to go into agroforestry practices (e.g. snail farming, bee keeping, fish farming, and vegetable production)
in efforts to reduce deforestation, which are currently less promoted.

Forestry is a productive sector with significant effects on meeting national socio-economic and environmental functions as
well as the improvement of rural livelihoods. Non-wood forest products (NWFPs) in particular have been widely advocated by
conservation and development organisations as potential alternative livelihood strategies, particularly among vulnerable forest
dependant households. Like in most tropical countries, NWFPs are relevant in the sustainable development of Kenya that is
particularly endowed with important forest resources. Kenya hosts about 17 million ha of forested land (about 3.51% of the
total Sub-Saharan Africa forest cover by 2000), of which about 16,865,000 ha is under natural forest (EarthTrends: Forests,
grasslands and drylands, 2003). Outside the gazetted forests, there are other large tracks of forests in trust lands, including
national parks and reserves, hill forest reserves and privately owned lands covering about 0.5 million ha (Kenya’s forest
resource assessment in the EC-FAO Partnership Programme Report, 2000; The Kenya Forests Act, 2005). Woodlands, bushlands and
wooded grasslands, mainly found in the arid and semi-arid lands cover 37.6 million ha, while forest plantations (started in
1946) cover about 170,000 ha of land (The Kenya forestry master plan, 1994–2020, 1994). In most NWFPs endowed regions of the
country however, this socio-economic and environmental potential is still unrealized. We illustrate the latter by a case study
of NWFPs use and management in four villages in Mbooni Division of Makueni District, Kenya. The division was chosen because
of its relatively high NWFPs availability, particularly from South Mbooni forest that is located at a distance less than 5 km
for an estimated 80% of the interviewed households. Data used for the analysis was collected through a fieldwork survey carried
out on women (35+ years) in August, 2005. One hundred and sixty (160) NWFPs are harvested (from plant and animal species)
and used mainly for food, income generation (supplemental) and medicinal purposes. A number of challenges limit women’s enjoyment
of the full benefits from NWFPs exploitation, the overriding problem being their inadequacy (in quantity and/or quality).
In this paper we discuss these commonly utilized and managed NWFPs plant species in Mbooni and their potential contribution
to improved livelihoods and sustainable development in Mbooni, Kenya and Sub-Saharan Africa (SSA) in general. 相似文献

A longitudinal survey was applied to 499 smallholder agriculturalist households in Mexico’s southern Yucatán region to determine
whether different cultural expectations had led to the formation and coexistence of different types of human–environment interactions.
A three center cluster analysis was used, and two agricultural adaptive strategies were found to coexist: a diversified subsistence
strategy built largely by individuals who were smallholder agriculturalists in their place of origin, and one generated mostly
by non-agriculturalists who migrated to the southern Yucatán to make agriculture their business during the last agrarian reform.
Each strategy followed unique family trajectories and established distinct human–environment interactions. The findings suggest
that those who emphasize commercial agriculture have a better standard of living. Nevertheless, their improved on-farm livelihoods—judged
by material, physiological, and educational indicators—comes at the cost of higher risks to their adaptive system and adverse
environmental consequences. 相似文献

This study analyzes the sources of income inequality among ethnic minorities in the Northwest region—the poorest and highest inequality region of Vietnam. Using an analysis of Gini decomposition by income source, the results show that while agricultural income, notably crop income, considerably decreases income inequality, off-farm income sources (wage and non-farm self-employment incomes) are found to increase inequality. This can be explained that in comparison with other income sources, agricultural income is more equally distributed and the main income source for most poor households. However, off-farm income sources are more unequally distributed and flow disproportionately toward the better-off. The findings support the hypothesis that income diversification in non-farm activities results in either greater inequality if opportunities for these activities are skewed toward to the better-off or less inequality if such opportunities are accessible to the poorer part of the population. 相似文献

Peri-urban pressure on the Luki Biosphere Reserve in Bas-Congo, Democratic Republic of Congo, is fuelled by growing demand in urban markets coupled with easy access. With data from 175 randomly selected households, this paper examines factors that motivate households to collect two major forest products found in the reserve for cash. We analyse the factors determining the choice of engaging in collection of bushmeat and eru (Gnetum africanum) and the factors determining the success (outcome) in collection using the Heckman selection model. This model explicitly separates estimation of selection into the activity from the outcome, to provide unbiased estimates of both. Results show that being local, higher household labour availability and higher asset endowment were positively related to selection into bushmeat hunting, reflecting higher risk-carrying capacities, ease of access to equipment and resources. Greater market distance being a female-headed household and greater age of household heads negatively affected selection into eru collection, reflecting characteristics of cash harvesting activities. Low education and more local knowledge characterised more successful outcome of eru collection, whereas having more household labour tended to lower outcomes of both bushmeat and eru collection suggesting that labour pools engaged in these activities were not sufficiently skilled, or that a higher proportion was consumed in such households. We discuss our findings in relation to the role of these activities in providing a pathway out of poverty and stress the needs for better integration of conservation and development policies. 相似文献

Based on the survey data of typical villages in Shaanxi Province, China, the effect of social capital on the income gap of farmers’ households was analyzed using the Shapley value of the total amount of social capital and the social capital structure. The results show the following: first, social capital can expand the household income gap, and the effect of this index on the household income gap is 7.54%. Second, the indexes of the social capital dimension can expand the household income gap, and the structural effects of the household income gap on social networks, social trust, and social participation are 3.17%, 3.64%, and 0.65%, respectively. Third, no dimension of the path is the same as the effect on the household income gap. 相似文献

Does status matter in community-based forest management? If so, are the high-status households more benefited than the low-status households? What drives status differences, if any, in the appropriation of forest resources? To address these questions, we draw on a theory of status and resource use that defines one’s status as one’s relative position in a group on the basis of power, prestige, honor and deference. Following this perspective, we surveyed the heads of 341 forest-based rural households in India from 2009 to 2010. We find that collective actions themselves are status-driven and the high-status households are more interested and involved in status-maintaining collective actions such as decision-making and implementation, while the low-status households perform general tasks like forest patrol. Moreover, the high-status households derive benefits from local forest significantly more than the low-status households. Further, decomposition analysis shows that a household’s prestige and honor measured by its access to social resources, problem faced and useful contacts explain about 56 % of the status gap in forest benefits, while socioeconomic characteristics explain only 16 % of the gap. Thus, due emphasis on household status from a broader socioeconomic perspective is required to reduce inequality in participation and the distribution of forest benefits in co-management. 相似文献

中国省际间农村居民收入结构和收入差距分析 总被引:3,自引:0,他引:3
在计算基尼系数的基础上,文章得出了改革开放以来中国省际间农村居民收入差距不断扩大的趋势,收入基尼系数从1981年的0.095一直上升到了2003年的0.181,直到近年来,收入差距才开始略有缩小。文章从收入结构的视角研究了省际间农村居民收入差距产生的原因。首先利用1983-2008年较长时期的数据分析了农村居民收入结构的变化,发现从总体上而言,中国各地区农村居民的收入结构均表现出了农业收入比重减少,非农收入比重增加的明显趋势;然后运用基尼系数的分解方法实证分析了不同收入来源对于收入差距的影响,研究发现,工资性收入是差距促增的,是目前中国省际间农村居民收入差距扩大最重要的原因,而家庭经营性收入者起着差距促减的作用,转移性收入和财产性收入的不平等程度较高,但是由于其在总收入中的比例不高,对总的收入差距影响较小。最后,文章提出了缩小省际间农村居民收入差距的政策建议。 相似文献

Lantana camara. L (hereafter Lantana) was first introduced by the British into India in 1807 as an ornamental plant. Since then the species has spread across the length and breadth of the country. Attempts to control Lantana in India have not been successful. In this study, we analysed the use of Lantana by local communities in southern India and identified the possible causes and consequences of its use through the use of a household survey of the socio-economic profile of the user and nonuser households and an analysis of the ecological history of the communities. Communities have been using Lantana for over 25–30 years and apparently such use was not prompted by external agencies. The characteristics of user and nonuser households were similar, except that Lantana users were more literate and had a greater number of occupations per household than nonusers. Per capita income was similar between user and nonuser groups. For nonuser groups, their main income sources were from trading (44 %), wage labour (32 %) and forest resources (23 %). In contrast, the Lantana user groups substituted their loss of income from forest resources (7 %) by income from Lantana (46 %). The ecological history revealed that Lantana was adopted as a resource at a time when it was increasing in the landscape and traditional bamboo resources were in decline because of overuse by commercial enterprises and mast flowering. This change in ecological resource availability prompted a major shift in livelihoods for some in the area. 相似文献

Can Labor Out-Migration Reduce Firewood Consumption by Rural Households in Western Mountainous China
Abstract The relationship between out-migration of labor in the Qinling mountain area and households’ firewood consumption is explored. Migration and remittances reduce households’ firewood consumption due to increases in both income and opportunity cost of firewood collection. Previous studies have been equivocal because they ignored uncertainty in household economy, which is widespread in forest areas of less developed countries. This study provides additional insight by considering vulnerability and subjective assessment of poverty generated by unstable income and an uncertain future. We provide evidence that the amount of firewood consumed depends on income and opportunity cost of firewood collection, but also on a prudent consumption strategy, due to farmers’ subjective assessment of their future possible poverty. We also find out-migration of labor can reduce per capita firewood consumption but subjective poverty also acts against reduction of firewood consumption. 相似文献

Adaptation strategies to reduce smallholder farmers’ vulnerability to climate variability and seasonality are needed given the frequency of extreme weather events predicted to increase during the next decades in sub-Saharan Africa, particularly in West Africa. We explored the linkages between selected agricultural adaptation strategies (crop diversity, soil and water conservation, trees on farm, small ruminants, improved crop varieties, fertilizers), food security, farm household characteristics and farm productivity in three contrasting agro-ecological sites in West Africa (Burkina Faso, Ghana and Senegal). Differences in land area per capita and land productivity largely explained the variation in food security across sites. Based on land size and market orientation, four household types were distinguished (subsistence, diversified, extensive, intensified), with contrasting levels of food security and agricultural adaptation strategies. Income increased steadily with land size, and both income and land productivity increased with degree of market orientation. The adoption of agricultural adaptation strategies was widespread, although the intensity of practice varied across household types. Adaptation strategies improve the food security status of some households, but not all. Some strategies had a significant positive impact on land productivity, while others reduced vulnerability resulting in a more stable cash flow throughout the year. Our results show that for different household types, different adaptation strategies may be ‘climate-smart’. The typology developed in this study gives a good entry point to analyse which practices should be targeted to which type of smallholder farmers, and quantifies the effect of adaptation options on household food security. Subsequently, it will be crucial to empower farmers to access, test and modify these adaptation options, if they were to achieve higher levels of food security. 相似文献

Pinus roxburghii (chir-pine) and Quercus leucothchophora (banj-oak) are dominant forests of mountainous part of the Uttarakhand Himalaya. The continued anthropogenic disturbance
is opening the canopy, forming canopy gaps and as a result forest fragments are developing. Thus, the present study aims to
analyze variations in species richness and vegetational parameters in relation to canopy gaps in forests. Total species richness
was greater in open canopied forest compared to moderate and close canopied forests. In comparison between oak and pine forest,
it was greater in oak forest while the proportion of common species was low between oak—pine forests. Mean species richness
did not significantly vary from one canopy gap to another as well as in oak and pine dominated forest. This indicated that
dominant forest types played an important role to form the community structure. The shrubs richness were greater in closed
canopy and between the forests it was greater in pine forest. Tree and shrub density was low in open canopy while herb density
was high in moderate canopy. Thus, this study indicated that the dominant canopy species play an important role in deciding
the community structures especially the distribution of under canopy species. These parameters should be considered for conservation
and maintenance of plant biodiversity of a region. 相似文献
