Households in China’s Yunnan Province were surveyed to understand the impacts of hydropower development and resettlement on the agricultural livelihoods of rural villagers. Household-level data from this survey are analyzed to test whether income and landholdings vary by resettlement status. Independent sample t-tests and one-way ANOVAs are used to examine how resettlement status relates to income, land allotments, agricultural crops, and government subsides. Results showed that, contrary to predictions, resettlement corresponds to higher household incomes, while differences in landholdings were mixed. Results indicate that while productive landholdings are less for resettled households, new wage labor, government subsidies, and intensified agriculture may contribute to a higher annual mean income at the household level. However, the tradeoff of receiving wage income for reduced landholdings may be a significant vulnerability for the affected households of the Mekong River Basin, since this loss in productive land corresponds to a long-term loss in social security. 相似文献

Sri Lanka has a long tradition of forest product use. The relationship of people with a dry zone forest was studied using a sample of 48 households in two villages that varied in distance to the forest and access to the market. All households interviewed collected subsistence forest products and a majority of them also collected commercial products. The daily peak-season income from commercial gathering was 4.5 to 7.7 times the daily labor wage. There is a strong gender specialization, with commercial gathering dominated by men whereas subsistence gathering is almost exclusively the task of women. The average forest-derived household income in the village closer to the forest and with better market access was nearly double that of the other village. Family size as a proxy of labor availability was the main discriminating factor between those households who did and those who did not gather commercial products. A small inverse relationship between forest gathering and size of household agricultural land (particularly paddy rice) was observed. No clear relationship was found between total household income and forest derived income, contradicting the view that commercial forest gathering is an exclusive activity of the poorest households. 相似文献

The relationship between size of landholdings and household economic status is fairly clear, particularly in societies where agricultural exports dominate the economy. Less clear is the effect of differential access to and control of productive property within households and the ways in which it affects the economic opportunities of individual household members. This paper examines property holdings and inheritance patterns among coffeeproducing households in Costa Rica. I show that while cultural norms regulatin g labor contributions do affect the balance of authority within households, de facto property rights can significantly enhance an individual's decision-making power both within households and between generationally-related households. Unless new opportunities arise, as population increases, coffee production expands, and lands become increasingly scarce, we shall likely see increased stratification both within households—as women inherit less land—and among households, as some sons inherit at the expense of other sons and daughters. 相似文献

Socioeconomic variation in the growth status of 293 children, 6 through 13 years of age, from a rural subsistence agricultural community in southern Mexico was considered. Socioeconomic status was based on an index developed from landholdings, household goods, and occupation, and households were classified as high and low status. Growth measurements included weight, stature, sitting height, estimated leg length, arm and estimated arm muscle circumferences, triceps skinfold, and right gripping strength. The growth status of boys showed a clear socioeconomic differential, while that of girls did not. The results are consistent with the generalization that males are more influenced by environmental stresses than females, including, of course, the favorable stress of improved socioeconomic circumstances, even within seemingly single-class rural communities. 相似文献

Farm Households and Land Use in a Core Conservation Zone of the Maya Biosphere Reserve,Guatemala 总被引:1,自引:1,他引:0

This paper employs cross-tabular analysis, and multivariate and logistic regression to explore demographic, political-economic,
socioeconomic, and ecological patterns of farm households and land use outcomes in an emergent agricultural frontier: the
Sierra de Lacandón National Park (SLNP)-a core conservation zone of the Maya Biosphere Reserve (MBR), Petén, Guatemala. Data
were obtained from a 1998 probability sample of 241 farm households, the first large detailed household land use survey in
Guatemala’s Selva Maya-the largest lowland tropical forest in Central America. Virtually all settler households were poor maize farmers who colonized
the SLNP in search of land for subsistence. While they faced similar ecological and economic conditions, land use strategies
and patterns of forest clearing varied with demographic, household, and farm characteristics. Findings support and refute
elements from previous frontier land use theory and offer policy implications for conservation and development initiatives
in the Maya Forest specifically, and in tropical agricultural frontiers in general.

Maintaining and improving household food self-sufficiency (FSS) in mountain regions is an ongoing challenge. There are many facets to the issue, including comparatively high levels of land fragmentation, challenging terrain and transportation bottlenecks, declining labor availability due to out-migration, and low technical knowledge, among others. Using a nonparametric multivariate approach, we quantified primary associations underlying current levels of FSS in the mid-hills of Nepal. A needs assessment survey was administered to 77 households in Lungaun (Baglung District), Pang (Parbat District), and Pathlekhet (Myagdi District), with a total of 80 variables covering five performance areas; resulting data were analyzed using Classification and Regression Trees. The most parsimonious statistical model for household FSS highlighted associations with agronomic management, including yields of maize and fingermillet within a relay cropping system and adoption of improved crop cultivars. Secondary analyses of the variables retained in the first model again focused primarily on crop and livestock management. It thus appears that continued emphasis on technical agricultural improvements is warranted, independent of factors such as land holding size that, in any case, are very difficult to change through development interventions. Initiatives to increase household FSS in the mid-hills of Nepal will benefit from placing a primary focus on methods of agricultural intensification to improve crop yields and effective technology transfer to increase adoption of these methods. 相似文献

A questionary sent to 137 women who qualified in Glasgow during 1951–4 showed that of the 106 respondents 24% of the married women were unemployed and only 31% were working full-time. The married women had fewer qualifications than a matched group of male contemporaries, and fewer of those in hospital work were consultants. The married women in full-time work had fewer children and showed some differences in their background compared with those working part-time or unemployed. Most part-time workers were satisfied with their present posts and did not wish to work more. 相似文献

The highland forests of Madagascar are home to some of the world''s most unique and diverse flora and fauna and to some of its poorest people. This juxtaposition of poverty and biodiversity is continually reinforced by rapid population growth, which results in increasing pressure on the remaining forest habitat in the highland region, and the biodiversity therein. Here we derive a mathematical expression for the subsistence of households to assess the role of markets and household demography on deforestation near Ranomafana National Park. In villages closest to urban rice markets, households were likely to clear less land than our model predicted, presumably because they were purchasing food at market. This effect was offset by the large number of migrant households who cleared significantly more land between 1989–2003 than did residents throughout the region. Deforestation by migrant households typically occurred after a mean time lag of 9 years. Analyses suggest that while local conservation efforts in Madagascar have been successful at reducing the footprint of individual households, large-scale conservation must rely on policies that can reduce the establishment of new households in remaining forested areas. 相似文献

Population growth in Java paralleled the development of a colonial economy based on the production of export crops using Javanese land and labor. The increase in population may be interpreted as a demographic response to demand for labor within the family, created by the need to intensify subsistence production in the face of colonial demands on land, labor, and produce. 相似文献

Contribution of “Women’s Gold” to West African Livelihoods: The Case of Shea ( Vitellaria paradoxa ) in Burkina Faso. This paper (i) quantifies the contribution that Vitellaria paradoxa makes to the total income of rural households belonging to different economic groups in two areas of Burkina Faso; (ii) quantifies the involvement of women in shea nuts and fruits collection and processing; and (iii) empirically verifies the “gap filling” function of shea products in Burkina Faso by quantifying the commercialization and subsistence use of shea fruits, nuts, and butter between agricultural seasons. Based on data collected from structured household surveys used on a quarterly basis during a one-year period on 536 households, we demonstrate that the reliance on shea is generally high in the sampled populations, and is at its highest for the poorest households, for which it contributes 12 % of total household income. Moreover, shea nut collection and processing was found to provide a valuable source of cash income to female household members who otherwise have very few income possibilities. Finally, due to its ecology, shea fills in an income gap during a period where human activities are at their highest while income is at its lowest. Although shea is crucial for poor people’s livelihoods and for the generation of income for women, its harvesting and processing are time-consuming activities that generate low returns per unit of labor. We argue that shea collection and processing should therefore not be considered as a remedy to poverty but instead as a way for households to diversify their livelihood strategy and decrease their vulnerability to food insecurity and climate variability. 相似文献

This study investigates the nutritional status of native children in the highlands of Nepal (1,700–3,000 m) and explores the relationship between child mortality and surviving children's nutritional status. A random sample of 145 households from 11 villages in the Koshi Hill Zone in east Nepal was surveyed, and the nutritional status of the 438 children <14 years of age living in these households was assessed by means of anthropometry. We found a severe growth retardation in the Nepalese children compared to lowland reference groups as well as to highland children from the Andes. Child mortality and altitude are not significantly different between higher (Brahman and Chetri) and lower (Baisya and Sudra) caste households. A lower caste status and higher altitude of the household is associated with a significantly better nutritional status in offspring. In multiple regression analyses, improved nutritional status in children is significantly associated with lower caste (P = 0.001), higher altitude (P = 0.009), and less crowding (P = 0.001) but not with sibling mortality (P = 0.11). We thus conclude that nutritional status of children in households in the highlands of Nepal is associated with the household's socioeconomic status and altitude but not with mortality among siblings. © 1996 Wiley-Liss, Inc. 相似文献

Over the past several decades in China there has been a large amount of rural labor flow to non-farm industries as well as an increase in farmland transfers that have resulted in significant differentiation of farmer households and changes in agricultural land use pattern. For this study we developed an agent-based model to explore this process and the resulting concentration of agricultural production by characterizing the households’ decision-making behavior with respect to farmland transfer in Jinze Town, located in the developed eastern region in China. The model simulated the household agents’ farmland transfer behavior, reproduced the evolution and differentiation of household agents, and explored changes of farm area distribution across household types from 2005 to 2020. Small households, the dominant demographic as well the main agricultural producers at the beginning of the simulation, decreased radically and cultivated the smallest area of farmland by the end. In contrast, large-scale farming households increased rapidly and became the main agricultural producers. The majority of households entirely exited farming in favor of urban employment. We examine how farm households’ attributes influence their farmland transfer behavior and subsequent livelihood choices in the specific socioeconomic and political context in the research region. We conclude with policy suggestions for the provision of a favorable environment for both large-scale farm households and those who leave farming altogether. Our findings can provide references for land use policies in other transitional rural areas. 相似文献

Introduction
Reliance on out-of-pocket payment for healthcare may lead poor households to undertake catastrophic health expenditure, and risk-pooling mechanisms have been recommended to mitigate such burdens for households in Bangladesh. About 88% of the population of Bangladesh depends on work in the informal sector. We aimed to estimate willingness-to-pay (WTP) for CBHI and identify its determinants among three categories of urban informal workers rickshaw-pullers, shopkeepers and restaurant workers.Methods
The bidding game version of contingent valuation method was used to estimate weekly WTP. In three urban locations 557 workers were interviewed using a structured questionnaire during 2010 and 2011. Multiple-regression analysis was used to predict WTP by demographic and household characteristics, occupation, education level and past illness.Results
WTP for a CBHI scheme was expressed by 86.7% of informal workers. Weekly average WTP was 22.8 BDT [Bangladeshi Taka; 95% confidence interval (CI) 20.9–24.8] or 0.32 USD and varied significantly across occupational groups (p = 0.000) and locations (p = 0.003). WTP was highest among rickshaw-pullers (28.2 BDT or 0.40 USD; 95% CI: 24.7–31.7), followed by restaurant workers (20.4 BDT 0.29 USD; 95% CI: 17.0–23.8) and shopkeepers (19.2 BDT or 0.27 USD; 95% CI: 16.1–22.4). Multiple regression analysis identified monthly income, occupation, geographical location and educational level as the key determinants of WTP. WTP increased 0.196% with each 1% increase in monthly income, and was 26.9% lower among workers with up to a primary level of education versus those with higher than primary, but less than one year of education.Conclusion
Informal workers in urban areas thus are willing to pay for CBHI and socioeconomic differences explain the magnitude of WTP. The policy maker might think introducing community-based model including public-community partnership model for healthcare financing of informal workers. Decision making regarding the implementation of such schemes should consider worker location and occupation. 相似文献14.
In European cities, the rate of population growth has declined significantly, while the number of households has increased. This increase in the number of households is associated with an increase in space for housing. To date, the effects of both a declining population and decreasing household numbers remain unclear. In this paper, we analyse the relationship between population and household number development in 188 European cities from 1990–2000 and 2000–2006 to the growth of urban land area and per capita living space. Our results support a trend toward decreasing population with simultaneously increasing household number. However, we also found cites facing both a declining population and a decreasing household number. Nevertheless, the urban land area of these “double-declining” cities has continued to spread because the increasing per capita living space counteracts a reduction in land consumption. We conclude that neither a decline in population nor in household number “automatically” solve the global problem of land consumption. 相似文献

Existing longitudinal studies on the relationship between working time arrangements (WTA) and work-family conflict have mainly focused on the normal causal relationship, that is, the impact of WTA on work-family conflict over time. So far, however, the reversed relationship, that is, the effect of work-family conflict on adjustments in WTA over time, has hardly been studied. Because work-family conflict is highly prevalent in the working population, further insight in this reverse relationship is invaluable to gain insight into secondary selection processes. The aim of this study is to investigate whether work-family conflict is prospectively related to adjustments in work schedules, working hours, and overtime work, and to explore sex differences and different time lags in this relation. Data of the prospective Maastricht Cohort Study were used. To study the effect of work-family conflict on a change from shift- to day work over 32 months of follow-up, male three-shift (n?=?727), five-shift (n?=?932), and irregular-shift (n?=?451) workers were selected. To study effects of work-family conflict on reduction of working hours over 12 and 24 months of follow-up, respectively, only day workers (males and females) were selected, capturing 5809 full-time workers (≥36?h/wk) and 1387 part-time workers (<36?h/wk) at baseline. To examine effects of work-family conflict on refraining from overtime work over 12 months of follow-up, only day workers reporting frequent overtime work at baseline were selected (3145 full-time and 492 part-time workers). Cox regression analyses were performed with adjustments for age, educational level, and presence of a long-term illness. Work-family conflict was associated with a significantly increased risk of changing from shift- to day work over 32 months of follow-up in three-shift workers (relative risk [RR]?=?1.77, 95% confidence interval [CI] 1.19–2.63) but not in five-shift workers (RR?=?1.32, 95% CI 0.78–2.24) and irregular-shift workers (RR?=?0.81, 95% CI 0.50–1.31). Within day workers, work-family conflict among full-time workers was associated with a significantly increased risk of reducing working hours during 1 yr of follow-up in women (RR?=?2.80, 95% CI 1.42–5.54) but not men (RR?=?1.34, 95% CI 0.81–2.22). In part-time workers, work-family conflict was associated with a significantly increased risk of reducing working hours during 1 yr of follow-up both in women (RR?=?1.99, 95% CI 1.04–3.82) and men (RR?=?4.03, 95% CI 1.28–12.68). Whereas the effects of work-family conflict on a reduction of working hours somewhat decreased among female full-time workers after 2 yr of follow-up (RR?=?2.13, 95% CI 1.24–3.66), among male full-time workers the effects increased and reached statistical significance (RR?=?1.53, 95% CI 1.05–2.21). Work-family conflict was not significantly associated with refraining from overtime work over 1 yr of follow-up. This study shows that work-family conflict has important consequences in terms of adjustments in work schedules and working hours over time, with considerable sex differences. The study thereby clearly illustrates secondary selection processes both in shift- and day workers, with significant implications for labor force participation, emphasizing the need for prevention of work-family conflict (Author correspondence: Nicole.

This paper focuses on the changes occurring in households in the indigenous Rana Tharus community. I discuss the household not in terms of physical structure but instead on the social aspects: how people relate to each other through the lens of the household context. I argue that the fluid nature of households makes its flexible to different ecological environments and socio‐economic scenarios. My ethnography of Rana households clearly illustrated that the formation, structure and management of Rana households was fundamentally linked to people's livelihoods. Before 1950s, abundant land resources allowed Ranas to live in joint‐type households. This particular household arrangement not only fulfilled labour needs but also secured the mutual security for every household member. Gradually, undivided and big households (known in Rana as Badaghar) became the ideal model for Ranas as soon as such establishments did not become divided or separated. This household structure also served as an important safety net for most Ranas and fundamental to other social relationships especially Mukhiya (household head system) and Kurmaa (patrilineal kin). However, since the 1950s, new socio‐economic landscapes have significantly challenged the maintenance of traditional Rana households. Within the lifetime of most Ranas, they first experienced household fission and the disappearance of the Mukhiya system. The dynamic relationships between Rana household and new ecological, social and economic landscapes are explored here. It is concluded that the household is a critical institution allowing anthropologists to better understand the long‐term social impacts caused by state policies and ecological changes. This is because people often practice their new household relations in their everyday life as a response to environmental and livelihood changes. 相似文献

Gbu Glycine Betaine Porter and Carnitine Uptake in Osmotically Stressed Listeria monocytogenes Cells

The food-borne pathogen Listeria monocytogenes grows actively under high-salt conditions by accumulating compatible solutes such as glycine betaine and carnitine from the medium. We report here that the dominant transport system for glycine betaine uptake, the Gbu porter, may act as a secondary uptake system for carnitine, with a Km of 4 mM for carnitine uptake and measurable uptake at carnitine concentrations as low as 10 μM. This porter has a Km for glycine betaine uptake of about 6 μM. The dedicated carnitine porter, OpuC, has a Km for carnitine uptake of 1 to 3 μM and a Vmax of approximately 15 nmol/min/mg of protein. Mutants lacking either opuC or gbu were used to study the effects of four carnitine analogs on growth and uptake of osmolytes. In strain DP-L1044, which had OpuC and the two glycine betaine porters Gbu and BetL, triethylglycine was most effective in inhibiting growth in the presence of glycine betaine, but trigonelline was best at inhibiting growth in the presence of carnitine. Carnitine uptake through OpuC was inhibited by γ-butyrobetaine. Dimethylglycine inhibited both glycine betaine and carnitine uptake through the Gbu porter. Carnitine uptake through the Gbu porter was inhibited by triethylglycine. Glycine betaine uptake through the BetL porter was strongly inhibited by trigonelline and triethylglycine. These results suggest that it is possible to reduce the growth of L. monocytogenes under osmotically stressful conditions by inhibiting glycine betaine and carnitine uptake but that to do so, multiple uptake systems must be affected. 相似文献

Prior to 1975, agriculture in Ethiopia was organized largely under feudalistic/imperial arrangements. The Ethiopian military government (1974–1991)issued the Land Reform Proclamation in 1975 which nationalized and redistributed most of the agricultural land among rural households. Land redistribution was meant to achieve equal land area per household and improve agricultural performance. Sale of land and hiring of agricultural labor were prohibited and there were fears that livestock would be nationalized. Following the ousting of the military regime in 1991, there has been a reduction of the imperfections in rural factor markets. Results from a field survey in the central Ethiopian highlands indicate that selling, hiring, renting, and exchanging of agricultural land, farm labor, and animal traction are increasing. These changes will influence agricultural production in many ways, particularly if reform with respect to rural factor markets is encouraged and accorded appropriate policy support. 相似文献

2001: A Household Analysis of Huastec Maya Agriculture and Land Use at the Height of the Coffee Crisis 总被引:1,自引:0,他引:1
Over the last decade, historically low market prices for Coffea arabica have affected smallholder shade coffee-growing households throughout northern Latin America. In an effort to better understand
household response to the coffee crisis and associated landscape changes, this paper examines agricultural production choices
and land use patterns among Huastec Maya coffee-growing households. Using data compiled from 47 household interviews, I describe
the cultural-geographical landscape in which the Huastec Maya land use system is embedded. In addition, I examine the economics
of household production through a financial cost-benefit analysis and through an exploration of the relationship between land
availability and land use patterns. Results show that economic inputs and returns from agriculture are highly variable, and
that, in 2001, coffee cultivation was not a viable cash-generating strategy for most households. Land availability was found
to have a significant effect on land use decisions, especially the proportion of land area devoted to fallow. Most importantly,
however, the case study suggests that a purely economic approach does not suffice in explaining why the Huastec Maya continued
to grow coffee in 2001, after years of low prices. Household production choices and livelihood strategies must also be viewed
within a cultural context. 相似文献

Datoga herding follows a cyclical pattern depending on the availability of grazing and water. This analysis focuses on two questions: (a) Is the herding strategy followed by individual households limited by the amount of labor available to that household? and (b) does the herding strategy followed by individual households influence the dynamics of cattle herds? The results show that the availability of labor on a household level does not influence either the herding strategies used by individual households, or the dynamics of cattle herds. This suggests that once minimum labor requirements are met, livestock productivity is insensitive to additional labor inputs. 相似文献
