Chronic food production deficits since the early 1970s have prompted policymakers of Burkina Faso to emphasize technological research with the goal of increasing the production of the most-consumed locally-grown cereals: sorghum, millet and maize. Meanwhile, urban consumers have been developing preferences for rice and wheat, cereals that are primarily imported. This study estimates demand relationships among food items in Ouagadougou, Burkina. The results of the estimation suggest that prices, income, household composition, education, marital status and urbanization were jointly important in explaining household expenditure allocations. Both local and imported cereal consumption responded positively to an income increase. However, incremental income changes would lead to relatively greater consumption of locally produced cereals by low-income households whereas high-income households would consume relatively more wheat and rice. The household model is then used to demonstrate its relevance in addressing food policy issues, by forecasting the levels of urban grain demand under alternative income and demographic scenarios. With increased production due to advances in technology, the urban demand levels do not exhaust the rural surplus of local cereals, but deficits persist in the rice-wheat sector. The results underscore the importance of technological research since Burkina could become self-sufficient in at least the production of sorghum, millet and maize.  相似文献

In recent years, the densely populated region around the burgeoning city of Kano in northern Nigeria has been the focus of much academic enquiry into the links between vegetation modification and fuelwood production and consumption. While many scholars have praised the socio-economic and ecological sustainability of Kano's rural–urban interface, arguing that indigenous agro-forestry systems will continue to resist urban fuelwood pressures for many years to come, other less optimistic observers have warned that exposure to a rapidly changing world economy is challenging traditional resource management systems like never before. Focusing on the case of Kano and its resource hinterlands, recent field-based evidence presented in this paper suggests that the latter supposition may be gaining increasing currency. In peri-urban regions, the rising prices of kerosene and other petroleum-based domestic fuels, coupled with the economic knock-on effects of a current petro-boom, are making fuelwood a much more attractive alternative as a domestic fuel choice. As lower and middle-income households shift away from commercial petroleum-based energy sources in favour of cheaper and more readily available biomass alternatives, it may be placing increased pressure on woodland resources and Kano's surrounding rural ecology: in the hinterlands of the city, local perceptions of research informants suggest that deteriorating economic conditions have driven some individuals to ‘step up’ fuelwood production to meet rising peri-urban demands. Although the intention of the paper is not to perpetuate crisis narratives or to suggest that fuelwood demand is causing runaway deforestation, the evidence presented does suggest that as conventional fuels become progressively more expensive, the poorest and most disadvantaged households may find it increasingly challenging to meet their basic energy needs.  相似文献

This paper investigates how Forest User Group (FUG) management of community forests and household characteristics influence household allocation of male and female labor to fuelwood collection in rural Nepal. FUG collection bans are found to displace both landed and landless female fuelwood collection labor to other forests that are typically further away, but lower restrictions do not. A higher female FUG executive committee share has both conservation and equity enhancing effects by lowering the likelihoods that landless, Dalit, landed and non-Dalit women collect in other forests, and increasing the likelihood landless males collect in the FUG forest.  相似文献

Chinese animal product consumption behaviour was analysed for both urban and rural households using a complete regional consumption dataset that was augmented to include away-from-home consumption. Seven animal product expenditure share equations were estimated with an extended Almost Ideal Demand System model. The results suggest that Chinese consumers will continue to increase their consumption of animal products, but that consumption patterns have changed in the 1990s. A large percentage of household animal product expenditure is still on pork. However, the shares for aquatic and poultry products consumption will increase substantially. As a consequence, the pork expenditure share will be gradually reduced as incomes grow and diet preferences change in both urban and rural households. There are significant differences in animal product consumption preferences across regions of China. As a result, studies that omit regional dummy variables in their demand systems can produce different expenditure and price parameters. The present paper also found that many of the estimates of elasticities and marginal expenditure shares would be rather different if the data ignored consumption away from home.  相似文献

Forestland tenure and financial incentives are the most important policy issue to sustainable forest resource management. The new wave of reform of collective forestland tenure (NRCFT) has been launched since 2003 and the governmental matching reform measures (MRMs) for the NRCFT have been introduced since 2009. The objective of these reforms is to enhance sustainable forest resource management in Chinese collective regions by encouraging rural households’ productive forest inputs. We use a unique dataset of 1778 sample households in 18 counties of nine provinces with six years and employ a fixed effects model with clustered standard errors. Our empirical results indicate that: 1) the NRCFT has increased households’ forestland area of different tenure types, and the effects of the MRMs on rural households’ labor input and production expenditures for forestry purposes are generally positive, especially household used forestland as collateral for a loan and afforestation or reafforestation subsidy and reform of Annual Allowance Cut (AAC) have significantly contributed to increase in the use of productive forest inputs; 2) the NRCFT and the MRMs have different impacts on the use of productive forest inputs for different tenure forests, and these reforms have caused the most significant changes in rural households’ production decision changes for household responsibility forestland; 3) both the NRCFT and the MRMs have significant effects on rural households’ rent-in and rent-out forestland; and 4) forestland fragmentations have caused additional labor and investment inputs for rural households’ forest resource management and protection. And finally, market drivers and household and village characteristics factors also affect households’ decisions for productive inputs for their managing forests.  相似文献

Rural households in Ethiopia have limited options to meet their domestic energy needs because they lack access to modern fuels and technologies. Domestic use of certain fuel sources, such as cow dung, can hinder agricultural outcomes and productivity. This article explores the tradeoffs between domestic and productive uses of biomass energy sources in the Nile Basin of Ethiopia using a nonseparable farm household model where labor allocation to energy collection and farming are analyzed simultaneously. We estimate a system of five structural equations using three‐stage least squares and find that the use of dung as a domestic fuel source has negative implications for the value of harvested crops, while use of on‐farm fuelwood is associated with increased value of agricultural output. On‐farm production of fuelwood appears to increase the value of crop output and provide labor savings, by making fuelwood collection more convenient for households. Policy interventions to support the expansion of agroforestry and increase access to new energy‐efficient technologies are needed to ensure that agricultural productivity can be both increased and sustained.  相似文献

The primary objective of this paper is to describe household rice consumption patterns in Nigeria with evidence from Imo State, determine the nature, magnitude and direction of income, price and cross price elasticities of demand, and examine the factors influencing household rice consumption. A budget survey of 50 randomly selected rural and urban households in Imo State, Nigeria, interviewed. The survey was repeated for 14 months between November 1984 and January 1986, providing the data used for analysis. There were significant differences between urban and rural household per capita daily rice consumption. Income (expenditure) elasticity of demand was greater than unity, and decreased, as expected, from low to high income groups. Household income was the most important determinant of food consumption. The implications of these findings for food and international trade policy are discussed.  相似文献

基于2016年福建省林权改革监测调研数据,利用二元Logistic模型,分析影响福建省欠发达山区林农参与碳汇林生产经营意愿的因素;贫困户与非贫困户对碳汇林项目经营意愿是否有差异及产生差异的原因。结果表明:贫困户与非贫困户对于碳汇林项目的响应程度有一定的区别,对于全体受访对象和非贫困户,是否参加过碳汇林生产培训、家庭林地面积、家庭林业总收入对提高其参与林业碳汇项目的意愿有显著的促进作用,而木材采伐销售收入反向影响其参与林业碳汇项目的意愿;对于贫困户,是否参加过碳汇林生产培训显著影响其参与林业碳汇项目经营的意愿。因此,提高贫困户和非贫困户的碳汇林经营意愿应各有侧重,在政策的制定上应给予贫困户一定的倾斜,调动贫困户的经营积极性,拓宽收入渠道,最终实现精准扶贫。  相似文献

Rural nonfarm income and its impact on agriculture: evidence from Albania   总被引:2,自引:0,他引:2  
Using data from the 2005 Albania Living Standards Measurement Study (ALSMS05) survey, this article analyzes the overall impact of household nonfarm income-generating activities (RIGA) on agricultural expenditures as well as technical efficiency of rural farm households. We also differentiate the impact for subsistence and commercial farmers, who are in the top 25% of the distribution of value of annual agricultural sales. Our results show that on the whole, Albanian rural households utilize their nonfarm earnings not to invest in time-saving, efficiency-increasing technologies, but to move out of crop production. We derive similar findings when we try to estimate the same relation separately for commercial and subsistence farmers. However, for commercial farmers, we find a positive impact of household nonfarm earnings on livestock expenditures.  相似文献

Household size and residential water demand: an empirical approach*   总被引:1,自引:0,他引:1  
The effectiveness of pricing policies depends on the price elasticity of consumption. It is well documented that residential demand for water is influenced by heterogeneity associated with differences in the size of the household and socioeconomic characteristics. In this paper, we focus on household size. Our initial hypothesis is that users’ sensitivity to changes in price is different depending on the number of household members. To this end, we carry out an empirical estimation of urban water demand in Zaragoza (Spain) distinguishing between households with different sizes using data at the individual level. As far as we are aware, this approach to urban residential water demand is new in the literature. The analysis suggests that all households are sensitive to prices regardless of size. A more relevant finding is that small households are more sensitive to price changes.  相似文献

This study assesses the livelihoods of rural households in a proposed green field forestry area located in Sanga district of Niassa province, Mozambique. The livelihood analysis was used to analyze potential socio-economic impacts of introducing forest plantations to rural households located within the proposed afforestation area. The study made use of household interviews, key informant interviews and secondary data. The sustainable livelihoods framework was used in the research process to develop the household questionnaire and to identify livelihood strategies. Data were analyzed using 331 household questionnaires collected throughout the proposed afforestation area in various communities in the study area. Findings from the study indicated that there is minimal wealth gaps between rural households; but that the introduction of the forestry industry and the subsequent employment created thereof may result in larger wealth gaps between wage earning and non-wage earning households. The study further concludes by linking the potential socio-economic impacts with mitigation recommendations that could be harmonized with FSC Standard requirements for forestry companies interested in developing a forest industry in the study area.  相似文献

Payments for Ecosystem Services (PES) is increasingly used in developing countries to secure the sustainable provision of vital ecosystem services. The largest PES programs in the world are embedded in China’s new forest policies, which aim to expand forest cover for soil and water conservation and improve livelihoods of rural people. The objective of this study is to identify the complex pathways of the impacts of two PES programs , the Conversion of Cropland to Forest Program (CCFP) and the Ecological Welfare Forest Program (EWFP), on household livelihood decisions, and to quantify the direct and indirect impacts along the identified pathways. We fulfill this objective by developing an integrated conceptual framework and applying a Partial Least Squares-Structural Equation Model (PLS-SEM), based on household survey data from Anhui, China. Labor allocation (for on-farm work, local paid work, local business, or out-migration) and land use decisions (i.e., rent in, maintain, rent out, or abandon cropland) for participating households are key to understand PES program effects on livelihoods. Results show that the PES programs have only small direct effects but significant indirect effects via the mediating factor of capital assets. Moreover, group heterogeneity analysis shows that lower-income households do not benefit more than the better-off households from the PES programs, while households with medium wealth increase dependence on agriculture. In addition, household demographics, individual attributes, and geographic settings differ in their impacts on labor allocation and land use decisions. We conclude that CCFP and EWFP would be more efficient in conserving the environment while improving the economic welfare of lower-income households if capital assets were taken into account in the design of compensation schemes.  相似文献

China’s Returning Farmland to Forest Program (RFFP) aimed to transform rural landscapes and livelihoods by compensating households for planting trees on retired farmland. The program has been attributed a key role in an apparent forest transition. Studies uncover great local variation in its impacts, but the mechanisms behind them have received little attention. We examine such heterogeneity in 12 communities in northwest Yunnan, assessing the hypothesis that the RFFP catalyzed a state-led forest transition by evaluating the contributions of RFFP implementation and other processes to land cover change. Our dataset combines socioeconomic data from household surveys, focus groups, and intensive interviews with remote sensing data for a linked, cross-scale analysis. Results show no significant relationship between RFFP implementation and community-level vegetation cover change. Between 2000 and 2010, high-elevation communities had larger vegetation gains, while from 2010 to 2014, low-elevation communities had larger gains. Regression analyses and interview data show off-farm labor, tree crop planting, and changing energy sources influenced the rate of community-level vegetation change. This pattern, combining tree crop cultivation with labor outflows, may represent a distinct “policy plantation” pathway of forest gain. Meanwhile, new, high-elevation cash crops may be constraining forest expansion. This analysis suggests limited additionality for the RFFP in this region and highlights how heterogeneous, intersecting land use processes bring uneven forest transitions.  相似文献

Haiti, with a forest cover estimated at 3% of all land area, has experienced severe degradation of its natural resources and a significant change in its land cover. While deforestation in Haiti is obviously multifaceted, one issue emerges from previous empirical analysis in explaining deforestation: land tenure. This study focuses on the causes of deforestation in Haiti, particularly in Forêt des Pins Reserve, using the annual average area of cleared forest per household as the dependent variable. Data were collected with the use of a survey instrument administered to 243 farm households in 15 villages inside the Reserve. Tobit Regression results reveal that household size, education of head of the household, land tenure regime, and farm labor are important factors affecting land clearing.  相似文献

In this paper the increasing importance of household production to total food supply in Russia is analysed and its relevance to agricultural reform discussed. The structure and profile of production are described and its incidence amongst households quantified. Factors influencing production are identified, and distinguishing characteristics between urban and rural households are highlighted and given historical context. The market share of output traded is also estimated. Finally, it is argued that the relationship between rural household production and large‐scale farming operations has impacted on continuing attempts to re‐structure socialised agriculture.  相似文献

We extend the Tobit (censored) linear equation system procedure to utility‐theoretic demand functions, along with a mapping mechanism to impose the adding‐up restriction implied by consumer utility maximization theory—a theoretical restriction very often ignored in previous empirical studies with censored demand systems. In this context, the Bayesian Markov Chain Monte Carlo (MCMC) procedure is applied to the censored linear approximate almost ideal demand system (LAIDS) for 12 food products, using data from the Turkish Household Expenditure Survey. All own‐price elasticities are negative and expenditure elasticities positive. Uncompensated own‐price elasticities for rural households are generally much higher than those for their urban peers, though demand for most food products are own‐price elastic for both types of households. The differential patterns in demand elasticities between urban and rural households become even more evident (almost twice) as relatively more expensive foodstuffs are consumed, showing that accessibilities to alternative products have made rural Turkish households more cognizant toward price changes in foods. Household characteristics play a key role in food expenditures, notably so in urban areas, and regional and seasonal differences are also present.  相似文献

We evaluate the effect of large-scale violent conflict on the household composition of internally displaced persons using quantitative data from Colombia. We use a panel database of migrants constructed with the Sisben database (used to target social programmes in Colombia) for 2006–2009. We follow migrant mothers and children who belong to nuclear-biparental households before migration, and analyse the changes in the composition of their households after migration through multilevel multinomial logistic models. We do this separately for rural and urban migrants because they exhibit differences in household composition traditions and exposure to armed conflict. We find that urban and rural migrants have different migration strategies in both peaceful and armed conflict circumstances. We conclude that the household compositions of mothers and children are differently affected by violence, which might be caused by family separation; for example, rural children have a higher probability than mothers of belonging to households which are not nuclear biparental. We also find that exposure to violence can increase or decrease the effects of individual variables; for instance, in peaceful situations it is more likely that a household remains intact during migration when the number of children per adult increases; however, this effect is attenuated in violence situations.  相似文献
