Technology,market policies and institutional reform for sustainable land use in southern Mali

To identify appropriate interventions that support sustainable land use; a farm household modelling approach is applied to analyze micro-economic supply reactions to various policy measures. The modelling framework links agro-technical and economic data, and takes both production and consumption decisions into account, allowing land use and production technology adjustments in accordance with farm household objectives. Different types of farm households are distinguished on the basis of their resource endowments, savings coefficients and time discount rate. Actual and alternative (sustainable) cropping and livestock activities for different weather regimes are defined for southern Mali. The effects on sustainable land use and expected farm household welfare of adopting alternative technologies and modifying prices, transaction costs, access to credit and land taxes are demonstrated. Even with full information on sustainable technologies, strong policy interventions are required to halt soil degradation. Structural policies proved to be more effective than price policies to reduce soil degradation while maintaining positive income effects. When prices are determined endogenously, structural policy loses some effectiveness as an incentive for sustainable land use due to the effect of additional supply on local cereal and meat Prices.     

FINANCIAL STRESS AND CONSUMPTION EXPECTATIONS AMONG FARM HOUSEHOLDS: NEW ZEALAND'S EXPERIENCE WITH ECONOMIC LIBERALISATION

A review of New Zealand's experience with assistance to agriculture through the 1960s and 1970s and the subsequent deregulation of the sector in the mid-1980s provides background to this study. Data for sheep and beef farmers are used to elaborate the variety of financial changes in the boom and bust cycles that followed the policy changes. Changes in farm business stress are examined using some conventional financial ratios. New measures which partition household expenditure between consumption and investment are then developed. These better explain the stress experienced among farm households as a consequence of the readjustment process and provide insight to the impact of the legacy of debt, encouraged by government intervention, on farmers' current and expected household consumption over recent years. New Zealand's experience reveals that farm household consumption stress has been unevenly distributed. This suggests that policy concern, following the removal of government assistance to agriculture, should focus principally on the mitigation of the household distress caused by ongoing farm debt commitments.     

Has China’s new round of collective forest reforms caused an increase in the use of productive forest inputs?

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.     

Urbanization strategies, rural development and land use changes in China: A multiple-level integrated assessment

This paper links urbanization strategies to changes in land use and associated impacts on rural communities and agro-ecosystems in a rural area of China. Energy, monetary and human time variables as well as information on environmental pressures, have been combined to compare different typologies of households and the metabolism of different patterns of land use from an integrated perspective. The results show that urbanization strategies, aimed at shifting the current land use and at displacing the local population, while increasing the economic efficiency is also associated with an increase in fossil energy consumption and environmental pressure, as well as a reduction of the multifunctional characteristic of the area under investigation. Based on these findings the paper also offers a critical discussion of the Chinese rural development policy arguing that the multifunctionality of rural areas should be taken into account by Chinese policy-makers and planners as a viable strategy to achieve rural development targets.

Internet Access and Farm Household Income – Empirical Evidence using a Semi‐parametric Assessment in Taiwan

There is considerable literature examining individuals’ behaviour with respect to Internet use, but less attention is paid to farm household use of the Internet. Among the few studies on farm households, the emphasis is on the correlation between socioeconomic factors and the adoption of the Internet. Thus, relatively little is known about the association between Internet use and farm household well‐being. In an effort to fill this void, this paper investigates Internet access among farm households and examines the effects of Internet access on farm household income. Given the observed income gap between Internet users and non‐users, we then investigate the extent to which socioeconomic factors may be associated with this income gap. Using a nationwide survey of farm households in Taiwan, a novel econometric model is proposed and estimated employing a semi‐parametric technique. Our results support the conclusion that Internet use improves farm household income. Most of the income gap between adopters and non‐adopters can be explained by the differences in the return of the socioeconomic factors.     

林业补贴政策对浙江林农营林投入和收入影响分析

基于浙江省3县368户农户的调查数据,采用双重差分模型(DID)研究实施中央财政林业补贴政策对林农营林投入和收入的影响。结果表明:实施林业补贴政策可以显著增加农户的营林投入,但对农户的营林增收没有显著带动作用,这证明林业补贴能够有效刺激林农的营林积极性,但增收效果仍有待观察。因此,选取林业补贴对象应注重"普惠+特惠"制、林业补贴政策需长期稳定执行、政府部门应加强林业补贴政策的宣传力度。     

Managing the energy trilemma of reliability,affordability and renewables: Assessing consumer demands with discrete choice experiments

In response to the looming climate crisis, many countries are adopting technologies to reduce the accumulation of greenhouse gases. However, national energy policies are often multiobjective and resolution deeply divisive. The result is a policy trilemma between the energy mix and the trade-offs with other policy objectives, including cost and reliability. Utilising a discrete choice experiment (DCE), the objective of this study is to explore Australian household preferences for alternative electricity contracts containing features reflecting changes in future energy policy. The first set of features include investments in renewable generation and community-based energy storage. The second set of features reflect demand-side management policies, including installing smart meters and consumption limits being imposed on households during peak demand. Two versions of the DCE were developed to obtain both willingness to pay and willingness to accept estimates for the same features. In line with the literature, differences in the two sets of estimates were observed, with the willingness to accept estimates being statistically larger for some features. These dollar value measures can be used to support public policy decision-making – the choice of which depending on the context of the policy problem being considered.     

Global market shocks and poverty in Vietnam: the case of rice

World food prices have experienced dramatic increases in recent years. These “shocks” affect food importers and exporters alike. Vietnam is a major exporter of rice, and rice is also a key item in domestic production, employment, and consumption. Accordingly, rice price shocks from the world market have general equilibrium impacts and as such, their implications for household welfare are not known ex ante. In this article, we present a framework for understanding the direct and indirect welfare effects of a global market shock of this kind. We quantify transmission of the shock from global indicator prices to domestic markets. Then we use an applied general equilibrium model to simulate the economic effects of the price changes. A recursive mapping to a nationally representative household living standards survey permits us to identify in detail the ceteris paribus effects of the shock on household incomes and welfare. In this analysis, interregional and intersectoral labor market adjustments emerge as key channels transmitting the effects of global price shocks across sectors and among households.     

Household Food Demand in Burkina Faso: Implications for Food Policy

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.     

Location and uptake: integrated household and GIS analysis of technology adoption and land use, with application to smallholder dairy farms in Kenya

CIS‐derived measures of location and space have increasingly been used in models of land use and ecology. However, they have made few inroads into the literature on technology adoption in developing countries, which continues to rely mainly on survey‐derived information. Location, with all its dimensions of market access, demographics and agro‐climate, nevertheless remains key to understanding potential for technology use. The measures of location typically used in the adoption literature, such as locational dummy variables that proxy a range of locational factors, now appear relatively crude given the increased availability of more explicit GIs‐derived measures. This paper attempts to demonstrate the usefulness of integrating CIS‐measures into analysis of technology uptake, for better differentiating and understanding locational effects. A set of GIs‐derived measures of market access and agro‐climate are included in a standard household model of technology uptake, applied to smallholder dairy farms in Kenya, using a sample of 3330 geo‐referenced farm households. The three technologies examined are keeping of dairy cattle, planting of specialised fodder, and use of concentrate feed. Logit estimations are conducted that significantly differentiate effects of individual household characteristics from those related to location. The predicted values of the locational variables are then used to make spatial predictions of technology potential. Comparisons are made with estimations based only on survey data, which demonstrate that while overall explanatory power may not improve with CIS‐derived variables, the latter yield more practical interpretations, which is further demonstrated through predictions of technology uptake change with a shift in infrastructure policy. Although requiring large geo‐referenced data sets and high resolution GIS layers, the methodology demonstrates the potential to better unravel the multiple effects of location on farmer decisions on technology and land use.     

Does participation in the conservation reserve program impact the economic well‐being of farm households?

This study uses U.S. farm household survey data to examine how participation in the Conservation Reserve Program (CRP) affects farm household economic well-being. Further, the study also examines the effects of CRP participation on farm household consumption, income, and imputed savings. In contrast to previous studies that assume the relationships are homogenous across the population, quantile regression is used to investigate the association between CRP participation across the entire distribution of farm household consumption and income. Empirical findings suggest that the effect of CRP participation on household economic well-being differs across the income and consumption distribution. For households in the lower percentiles of the distribution, the CRP participation is associated with an increase in household consumption, but a decrease in farm household income and savings. In contrast, farm households at the median and higher income and consumption quantiles, participation in CRP is associated with lower levels of household consumption and income, but with higher levels of savings.     

Buffer stock savings by portfolio adjustment: evidence from rural India

The empirical literature on household savings tends to treat savings simply as the residual of income minus consumption. This article takes a unique approach to reconstruct the cash and asset balances using detailed household transaction data on farm households in rural India and generates monthly and seasonal ICRISAT panel data for the period 1976–1983. We have found that households—irrespective of their landholding status—cope with temporary shocks quite well by using crop inventory, currency, and capital assets, rather than livestock, as buffer assets. The importance of portfolio adjustments in smoothing consumption is also confirmed by the use of a system of equations in which both portfolio and production decisions are made endogenous. It is concluded that not only the level but also the diversification of household assets are important for buffering consumption. As an extension, we have explored the monthly ICRISAT panel data for the period 2009–2012 in the same villages and have found a similar pattern in household portfolio responses to income shocks.     

Nontraditional crops,traditional constraints: The long‐term welfare impacts of export crop adoption among Guatemalan smallholders

This article documents the long‐term welfare effects of household nontraditional agricultural export (NTX) adoption. We use a panel dataset that spans the period 1985–2005, and employ difference‐in‐differences estimation to investigate the long‐term impact of nontraditional agricultural export adoption on changes in household consumption status and asset position in the Central Highlands of Guatemala. Given the heterogeneity in adoption patterns, the analysis differentiates the impact estimates based on a classification of households that takes into account the timing and duration of nontraditional agricultural export adoption. The results show that while, on average, welfare levels have improved for all households irrespective of adoption status and duration, the extent of improvement has varied across groups. Long‐term adopters exhibit the smallest increase in the lapse of two decades, in spite of some early gains. Conversely, early adopters who withdrew from nontraditional agricultural export production after reaping the benefits of the boom period of the 1980s are found to have fared better and shown greater improvements in durable asset position and housing conditions than any other category.     

Household size and residential water demand: an empirical approach*

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.     

Modeling household behavior in developing countries: discussion

A large and growing body of literature has examined how agricultural households cope with risk. Much of the work has focused on which types of households are better able to smooth consumption, testing whether households with more resources and greater access to income-smoothing institutions, such as credit markets or well-functioning labor markets exhibit greater consumption smoothing. However, income shocks may have different effects upon different individuals within households, and differences in individual ability to smooth income or consumption may have welfare consequences which go beyond foregone income. The development of collective household models challenges the assumption that individuals within households maximize a single utility function. The assumption of income pooling has also been rejected in a growing body of empirical research on intrahousehold resource allocation. However, research on risk-pooling within households and differences in individual abilities to smooth consumption is relatively new. Selected papers are discussed.     

Household welfare implications of sustainable land management practices among smallholder farmers in Ghana

This study employs farm household data to examine the impact of adoption of sustainable land management practices on consumption and poverty outcomes using multivalued treatment effects approaches. The generalized propensity score approach was employed to account for selectivity bias due to observed characteristics among households. Using a doubly robust treatment effects estimator, we found that increasing intensity of adoption improved per capita consumption expenditure, reduced poverty headcount and poverty gap among farm households. The results of the multivalued treatment effects approach revealed significant differences between adopters of different adoption intensities, a finding that is not possible with binary treatment effect approaches. The findings also revealed that the average treatment effect of moving from low intensity to high intensity adoption levels differed across quantiles of per capita consumption. We also use a dose-response function to demonstrate that the treatment effect of intensity of adoption on per capita consumption and poverty outcomes is nonlinear, with optimal adoption level occurring between 60–70 % of adoption intensity dose. It is therefore recommended that initial government support in sustainable land management is necessary to sustain and upscale individual household efforts towards investment in sustainable land management.     

Expenditure Pattern for Food Away from Home Consumption in Turkey

ABSTRACT

One of the largest recent changes in consumer food purchasing behavior is the trend towards greater consumption of food eaten outside the home. Between 1994 and 2000, the share of total food expenditures spent on food away from home (FAFH) increased from 7 to 15% with an increasing share for fast-food facilities. This study focuses on whether demographic and socioeconomic factors have detectable effects on Turkish FAFH expenditures. This question is of interest because previous studies suggest that increasing household income, education, female labor participation and changing lifestyle especially in developing countries increased household FAFH consumption share but decreased food at home consumption share. However, no study to our knowledge has examined the combined effect of income, education, employment, and family status on Turkish FAFH consumption. The data for this research were obtained from personal interviews of representative sample households of the province of Adana in Turkey. The findings of this study generally indicate that restaurant facilities, employment of wife and education, composition of household, and income are statistically significant determinants of FAFH consumption.     

FARM HOUSEHOLD PRODUCTION IN THE PRESENCE OF RESTRICTIONS ON DEBT: THEORY AND POLICY IMPLICATIONS

In this paper a two period life cycle model of the farm household is constructed allowing for production and restrictions on debt in which the consumption and production decisions of the farm household are simultaneous. It is shown that the farm household's production responses to exogenous changes may be qualitatively different to that predicted by the profit-maximising model when all markets are perfect. In particular, when the household is debt constrained, ‘perverse’ output effects are possible with output increasing in response to output price decreases. Further, for such households, compensation payments will have production effects. Finally, the financial situation of the farm has an impact on production for debt constrained farms.
