Evaluating the role of livelihood assets in suitable livelihood strategies: Protocol for anti-poverty policy in the Eastern Tibetan Plateau,China

Although numerous studies have been conducted on the relationship between livelihood assets and strategies, only a few quantitative studies exist on the topic for anti-poverty policies with regard to the Tibetan Plateau. This study investigated 357 households in the upper reaches of the Dadu River watershed in the Eastern Tibetan Plateau, China, using the participatory rural appraisal method. Then, applying a multinomial logistic regression model, we quantitatively analyzed the relationship between livelihood assets and livelihood strategies, the findings of which have implications for local agricultural policy interventions. The preliminary results indicate that of the four classifications of livelihood strategies used in this study, the main livelihood strategy is that of the non-farming-dependent household type (i.e., Type III in our study) that combines agricultural and non-farm activities or practices self-employment for wages. There are significant differences in the livelihood assets owned by households with different livelihood strategies. Human, natural, and financial assets have significant influences on livelihood strategies, and the choice of livelihood strategy varies by livelihood assets. Further, with improvements in household labor capacity and cash income per capita, the livelihood strategies of non-agricultural and non-farming households may shift away from agriculture, while an increase in farmland cultivated per capita, cash income per capita, and household labor capacity may encourage households to adopt agriculture-dependent livelihood strategies. These findings contribute to research on livelihood and related development strategies and anti-poverty policies in not only the Eastern Tibetan Plateau but also other regions with similar livelihood strategies.     

农户生计与生态系统服务关系的区域差异及驱动机制——以密云水库上游流域为例

深入揭示生态系统与农户福祉之间的关系,对实现农户差异化管理及区域可持续发展具有重要意义。本研究以密云水库上游流域(包括北京市和河北省的部分区域)为研究区域,基于1754份农户调查问卷数据,通过统计计量方法对比分析了流域内北京市、河北省农户福祉水平(以家庭总收入表示)与生态系统服务依赖性(以生态系统依赖性指数表示)的关系。结果表明: 流域内京冀农户生计与生态系统的互作模式均可分为4类,但京冀两地不同模式占比差异较大。北京农户样本中,占比最高的是高福祉-低依赖模式(33.9%),农户人均年收入显著高于河北农户,农户的各项生计资本也较河北省农户高;河北农户中,不提倡的低福祉-高依赖模式仍占比39.1%,对提升农户福祉水平至关重要的人力资本素质、社会资本、金融资本等均显著低于北京农户;河北农户主要依赖农业生产收入(41.2%),对土地的开发利用程度显著较高;相对于北京农户,河北农户的自然资源条件、人力资本素质对农户生计的影响更加显著。保持适当家庭规模、不断提高劳动力教育水平、提高低收入家庭的生态补偿标准是形成农户与生态系统良好互动关系(高福祉-低依赖型)的关键因素。     

Determinants of bushmeat supply sources in rural areas of Côte d’Ivoire

The bushmeat trade provides an income to hunters, transporters, and vendors living in the vicinity of protected areas but remains a challenge to wildlife conservation objectives. The key factors driving the source, choice and use of bushmeat vary among actors in the commercial bushmeat value chain, and insights into these determinants are required to facilitate the development of conservation strategies. Therefore, we aimed to identify the socioeconomic factors that explain the source of supply and quantities of bushmeat available in households and local restaurants. We carried out a survey with 144 rural household heads and 24 restaurant owners in 20 villages in the Western part of Taï National Park in Côte d’Ivoire. We found that bushmeat quantity and species diversity were low in households, originating mainly from subsistence hunting. However, both the amount of bushmeat and the variety of species were high in restaurants and primarily supplied by commercial hunters. Furthermore, the quantity of bushmeat was lower in households with other protein sources and in restaurants in villages that had been the target of more conservation awareness campaigns. We highlight the importance of understanding the determinants of bushmeat supply to regulate the bushmeat trade by applying relevant conservation interventions.     

Rice and Remittances: Crop Intensification Versus Labour Migration in Southern Laos

Despite being a low-income, agriculture-based country with a subsistence orientation, Laos is in the early stages of a major economic transformation whereby rural households have been experiencing rapid change in their farming and livelihood systems. Some households have begun to engage in semi-commercial farming while others have adopted labour-oriented or migration-oriented livelihood strategies. This paper explores how rural households in six villages in the lowlands of Champasak Province in southern Laos make a living. These villages vary in their access to irrigation and to markets. Nevertheless, in all villages, long-term migration of younger household members to neighbouring Thailand has come to play a large role in household livelihood strategies. In some cases this is necessary to meet the household’s consumption requirements; in most, it is part of a diversified strategy in which rice farming still plays a significant role, though still largely for subsistence. The paper examines some of the issues involved in attempting to promote intensive, market-oriented rice farming in a context of an emerging on-farm labour shortage combined with an increasing flow of remittances from migrant family members.     

Incentives for Hunting: The Role of Bushmeat in the Household Economy in Rural Equatorial Guinea

Bushmeat is an important component of the informal economy throughout West and Central Africa. In order to formulate effective policy to ensure the sustainability of bushmeat hunting for both development and conservation reasons, there is a need to understand its position within the wider rural economy. We conducted interviews with households and hunters over a 15-month period in a village in continental Equatorial Guinea which supplies substantial quantities of bushmeat to the urban market, to evaluate (1) whether hunting is predominately for income or consumption and through choice or necessity, and (2) the factors influencing household production of and consumption and expenditure on bushmeat. Hunting for trade to urban markets is a major component of household incomes, carried out by around 60% of poor-to-middle income households, while richer households have other income-generating activities. The greater a hunter’s bushmeat offtake, the higher the proportion sold. Bushmeat forms a minor component of household expenditure and is less widely consumed than alternative protein sources. It is a necessity good, with consumption and expenditure on bushmeat related less than proportionately to income. While they prefer the security of a regular wage, hunting is an important source of fall-back income for men in the absence of preferable alternative livelihood opportunities.     

The Importance of Bushmeat in the Livelihoods of West African Cash-Crop Farmers Living in a Faunally-Depleted Landscape

Bushmeat is an important resource in the livelihoods of many rural communities in sub-Saharan Africa and may be a crucial safety-net for the most vulnerable households, especially during times of economic hardship. However, little is known about the impacts of wildlife depletion on these functions. This study quantifies the role of bushmeat in diversified rural household economies in a wildlife depleted forest-farm landscape in Ghana, assessing its importance overall, as well as differentiated by the relative vulnerability of households. Using repeat socioeconomic questionnaires (N=787) among 63 households over a one-year period, the following hypotheses were tested: (a) vulnerable households harvest more bushmeat; (b) bushmeat contributes a greater proportion of household production in vulnerable households; (c) bushmeat is more important for cash income than consumption in vulnerable households; and (d) bushmeat sales are more important for vulnerable households. The bushmeat harvest value averaged less than US$1.0 per day for 89% of households and comprised less than 7% of household production value. Household wealth and gender of the household head had little effect on the importance of bushmeat. However, bushmeat harvest and sales were highest during the agricultural lean season. Overall, most harvested bushmeat (64%) was consumed, enabling households to spend 30% less on meat/fish purchases. These findings suggest that, despite heavily depleted wildlife and diversified livelihoods, bushmeat continues to have an important role in rural livelihoods by acting as a safety net for income smoothing and reducing household expenditure during times of economic hardship.     

Child growth and the economic value of children in rural Bolivia

Previous investigations have yielded contradictory conclusions concerning the importance of the economic contribution of children to households in agricultural societies. The present study evaluates the significance of children 's economic input in rural Ancoraimes, Bolivia by using child growth as an indirect indicator of the economic value of children. Children whose households differed in size and age composition were compared on the basis of five anthropometric measurements. Children from households with many young, nonproducing children were found to be significantly smaller for their age than children from households with few nonproducing children. Absolute household size had no major effect on child growth. While young children have a negative effect on the growth of children in the household, the positive effect of children as they grow older appears to make up for this loss. In terms of child growth, children are neither a net liability nor a net asset to agricultural households in Ancoraimes.     

Household food group expenditure patterns are associated with child anthropometry at ages 5, 8 and 12 years in Ethiopia,India, Peru and Vietnam

Population-level analysis of dietary influences on nutritional status is challenging in part due to limitations in dietary intake data. Household expenditure surveys, covering recent household expenditures and including key food groups, are routinely conducted in low- and middle-income countries. These data may help identify patterns of food expenditure that relate to child growth.ObjectivesWe investigated the relationship between household food expenditures and child growth using factor analysis.MethodsWe used data on 6993 children from Ethiopia, India, Peru and Vietnam at ages 5, 8 and 12y from the Young Lives cohort. We compared associations between household food expenditures and child growth (height-for-age z scores, HAZ; body mass index-for-age z scores, BMI-Z) using total household food expenditures and the “household food group expenditure index” (HFGEI) extracted from household expenditures with factor analysis on the seven food groups in the child dietary diversity scale, controlling for total food expenditures, child dietary diversity, data collection round, rural/urban residence and child sex. We used the HFGEI to capture households’ allocations of their finances across food groups in the context of local food pricing, availability and pReferencesResultsThe HFGEI was associated with significant increases in child HAZ in Ethiopia (0.07), India (0.14), and Vietnam (0.07) after adjusting for all control variables. Total food expenditures remained significantly associated with increases in BMI-Z for India (0.15), Peru (0.11) and Vietnam (0.06) after adjusting for study round, HFGEI, dietary diversity, rural residence, and whether the child was female. Dietary diversity was inversely associated with BMI-Z in India and Peru. Mean dietary diversity increased from age 5y to 8y and decreased from age 8y to 12y in all countries.ConclusionHousehold food expenditure data provide insights into household food purchasing patterns that significantly predict HAZ and BMI-Z. Including food expenditure patterns data in analyses may yield important information about child nutritional status and linear growth.     

Dam-Induced Displacement and Agricultural Livelihoods in China’s Mekong Basin

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.     

可持续生计框架下连片特困区发展机理——以宁夏限制开发生态区为例

生计资本与农户收支有着密切关系,决定农户的生计策略,影响区域的发展机理与发展模式.基于参与式农村评估和数理统计方法,分民族、地形、农户类型对宁夏限制开发生态区农户生计资本与农户收支状况进行定量评估,创建农户非农性指数,揭示生计资本与农户收支和非农性指数的关系,结合研究区实际对农户可持续生计进行研究,探讨区域发展机理.结果表明: 研究区农户生计资本量整体偏低,其中,回族略高于汉族、川道农户高于山地农户、兼业户和非农业户显著高于农业户;区域发展与非农性指数和人力、物质等资本显著正相关,与自然资本显著负相关,需着力提升农户的非农性指数和人力、物质等资本量,同时引导农户对农业生产资料进行流转,促进自然资本两极分化.     

Impact of Community-Based HIV/AIDS Treatment on Household Incomes in Uganda

Though health benefits to households in developing countries from antiretroviral treatment (ART) programs are widely reported in the literature, specific estimates regarding impacts of treatments on household incomes are rare. This type of information is important to governments and donors, as it is an indication of returns to their ART investments, and to better understand the role of HIV/AIDS in development. The objective of this study is to estimate the impact of a community-based ART program on household incomes in a previously underserved rural region of Uganda. A community-based ART program, based largely on labor contributions from community volunteers, was implemented and evaluated. All households with HIV/AIDS patients enrolled in the treatment programme (n = 134 households) were surveyed five times; once at the beginning of the treatment and every three months thereafter for a period of one year. Data were collected on household income from cash earnings and value of own production. The analysis, using ordinary least squares and quantile regressions, identifies the impact of the ART program on household incomes over the first year of the treatment, while controlling for heterogeneity in household characteristics and temporal changes. As a result of the treatment, health conditions of virtually all patients improved, and household incomes increased by approximately 30% to 40%, regardless of household income quantile. These increases in income, however, varied significantly depending on socio-demographic and socio-economic control variables. Overall, results show large and significant impacts of the ART program on household incomes, suggesting large returns to public investments in ART, and that treating HIV/AIDS is an important precondition for development. Moreover, development programs that invest in human capital and build wealth are important complements that can increase the returns to ART programs.     

Coping Strategies among Urban Poor: Evidence from Nairobi,Kenya

Aims

In Kenya, it is estimated that 60 to 80% of urban residents live in slum or slum-like conditions. This study investigates expenditures patterns of slum dwellers in Nairobi, their coping strategies and the determinants of those coping strategies.

Method

We use a dataset from the Indicator Development for Surveillance of Urban Emergencies (IDSUE) research study conducted in four Nairobi slums from April 2012 to September 2012. The dataset includes information related to household livelihoods, earned incomes of household members, expenditures, shocks, and coping strategies.

Results

Food spending is the single most important component, accounting for 52% of total households'' income and 42% of total expenditures. Households report a variety of coping strategies over the last four weeks preceding the interview. The most frequently used strategy is related to reduction in food consumption, followed by the use of credit, with 69% and 52% of households reporting using these strategies respectively. A substantial proportion of households also report removing children from school to manage spending shortfalls. Formal employment, owning a business, rent-free housing, belonging to the two top tiers of income brackets, and being a member of social safety net reduced the likelihood of using any coping strategy. Exposure to shocks and larger number of children under 15 years increased the probability of using a coping strategy.

Policy Implications

Policies that contain food price inflation, improve decent-paying job opportunities for the urban poor are likely to reduce the use of negative coping strategies by providing urban slum dwellers with steady and reliable sources of income. In addition, enhancing access to free primary schooling in the slums would help limit the need to use detrimental strategies like “removing” children from school.     

How Well do Foragers Protect Food Consumption? Panel Evidence from a Native Amazonian Society in Bolivia

The ability of rural people to protect their food consumption matters because it captures their economic vulnerability. How well do foragers protect consumption from adverse income shocks and does protection work equally well for all people in the household? We answer the queries with data from 156 adults and 169 children collected over five consecutive quarters from the Tsimane’, a native Amazonian society of foragers and farmers in Bolivia. We estimate whether quarterly changes in the logarithm of consumption bear an association with quarterly changes in the logarithm of cash income while controlling for many confounders, including covariant shocks. We use anthropometric indices of short-run nutritional status to proxy for food consumption and use instrumental variables to abate biases from the endogeneity of income. We found that child consumption was fully protected from income growth, but adult consumption was not as well protected. Estimates of income elasticities of consumption fell toward the lower range of estimates from previous studies of farming and industrial societies. We present several hypotheses to explain how the Tsimane’ smooth consumption.     

Nontimber forest product extraction, utilization and valuation: A case study from the Nilgiri Biosphere reserve, southern India

We evaluated the diversity, social, and economic aspects of nontimber forest product (NTFP) collection in the Nilgiri Biosphere Reserve (NBR), in southern India. The NBR is a region known for its floral andfaunal diversity, as well as an area with increasing human pressure. Fifty to 75% of the households (HH) in rural areas gather a diversity of forest products. Dominant NTFPs contributed 25–60% of the average annual per capita household income from NTFPs. The mean annual per capita household income from NTFPs ranges between Rs. 134 and Rs. 4955. The mean annual income per hectare ranges from Rs. 93 in the montane zone to Rs. 3780 in the moist deciduous. NTFPs contribute 15–50% of the annual per capita income of rural households. Ethnicity plays an important role in the collection of NTFPs and ethnic tribes derive a large proportion of their annual per capita income from NTFPs.     

Characterizing Rural Household Differentiation from the Perspective of Farmland Transfer in Eastern China Using an Agent Based Model

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.     

Contribution of “Women’s Gold” to West African Livelihoods: The Case of Shea (<Emphasis Type="Italic">Vitellaria paradoxa</Emphasis>) in Burkina Faso

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.     

Do Markets Worsen Economic Inequalities? Kuznets in the Bush

Integration into a market economy or economic development can erode the quality of life of indigenous people by, for example, increasing income inequalities. The Kuznets hypothesis predicts that the link between income inequality and income (a proxy for economic development) resembles an inverted U. We test the hypothesis using a survey of 511 households from 59 villages of Tsimane' Amerindians, a horticultural-foraging society in the tropical rain forest of Bolivia. We measure village inequalities of three economic outcomes: income, imputed annual value of rice production, and wealth. We used three indices of inequality: the coefficient of variation, the standard deviation of the logarithm, and the Gini coefficient. Explanatory variables include either income and income squared, wealth and wealth squared, or imputed annual rice production and production squared. We used village-to-town distance as a control. We find little evidence that integration to the market increases inequalities of economic outcomes, with two exceptions: Wealth bore the predicted inverted U-shaped relation with wealth inequalities, and imputed rice production bore a U-shaped relation to inequality, but only when (a) using adult equivalents to express household size and (b) the Gini coefficient and the coefficient of variation to measure inequality; in no case were results robust to different econometric specifications. We advance several explanations for why economic development might not accentuate economic inequalities among relatively autarkic rural economies.     

农户薪柴消费的理论模型及实证研究

农户薪柴消费变化对室内空气质量、农村生态环境建设影响重大,论文构建了山区农户薪柴消费的理论模型,以重庆市典型区1015份农户调查数据为例,运用Tobit模型分析了农户人均薪柴消费量的影响因素。研究表明:农户家庭能源消费中,商品能源和新能源的比重逐步增大,但薪柴依旧是农户普遍使用的能源类型,且消费量占总能源消费量的比重高;通过降低农业劳动力比重和提高非农工资水平两种途径,非农就业能显著降低农户人均薪柴消费量;家庭电器数量增多、其他收入(政府补贴、亲戚帮扶等)增加、及替代能源(液化气、沼气、煤炭等)可获得性增强也能显著降低农户人均薪柴消费量,而户主年龄大、人均牲畜数量多及房屋离集市距离远的农户家庭的人均薪柴消费量高。提出了加快薪柴替代的措施。     

Misfortunes never come singly: Structural change,multiple shocks and child malnutrition in rural Senegal

This study considers the two most pronounced shocks Senegalese subsistence farmers struggle with, namely increasing purchase prices and droughts. We assess the relationship of these self-reported shocks with child health in a multi-shock approach to account for concomitance of adverse events from the natural, biological, economic and health sphere. We employ a unique farming household panel dataset containing information on children living in poor, rural households in eight regions of Senegal in 2009 and 2011 and account for structural changes occurring between survey periods due to the large scale, national Nutrition Enhancement Program. By zooming in to the micro level we demonstrate that Senegal as a Sahelian country, mainly reliant on subsistence agriculture, is very vulnerable to climate variability and international price developments: According to our conservative estimates, the occurrence of a drought explains 25% of the pooled weight-for-age standard deviation, income losses 31%. Our multi-shock analysis reveals that the shocks are perceived as more severe in 2011 with droughts explaining up to 44% of the standard deviation of child health, increased prices up to 21%. Yet, the concomitance of droughts and increased prices after the structural change, i.e. the Nutrition Enhancement Program, indicates that the health of children experiencing both shocks in 2011 has improved. We argue that these results are driven by the increase in rural household income as theoretically outlined in the agricultural household model. Thus, adequate policy responses to shocks do not only depend on the nature but also on the concomitance of hazardous events.
