Matching food security and malnutrition indicators: evidence from Southeast Asia

This article aims to understand the relation between household food security and individual undernutrition. The multitude of indicators available raises the question which aspects of food security are captured by the respective indicator. In our analysis, we first assess the relation between the dimensions of food security and households’ socioeconomic characteristics. Second, we examine whether household indicators detect undernutrition in children. Finally, we investigate the role of individual‐specific characteristics for child undernutrition. The analysis is based on a novel data set of 1,200 rural households from Cambodia and Lao PDR, which combines household‐ and individual‐level data. We capture household food security by three indicators including a dietary diversity score, a consumption behavior measure, and an experiential measure. Individual nutrition status is measured via anthropometric indicators. Our results show that different household‐level indicators capture fundamentally different aspects of food security. Moreover, household food security fails to explain stunting for children under five. Dietary diversity indicators, however, explain underweight in children to a small extent. We call for more research on intrahousehold allocation of food and stress the implications of our research for the design and targeting of food and nutrition support programs.     

Rural electrification in Cambodia: does it improve the welfare of households?

This study uses subsamples of socio-economic surveys from 2004 and 2011 to construct village panel data and apply the difference-in-differences (DID) method to examine the impact of rural electrification on household consumption and children’s education in Cambodia at the village level. Conditional on the DID assumption and observed village and household characteristics, rural electrification increased household consumption by approximately 16.6%. This study also finds that higher-quintile households benefited more. Additionally, rural electrification increased boys’ years of schooling completed by 0.85 and girls’ years of schooling completed by 0.62. It also increased the probability of having ever been enrolled in primary school for boys by approximately 9.7% but did not increase the probability of having ever been enrolled for girls.     

Childhood obesity in Mexico: the effect of international migration

This article estimates the effect of international migration from Mexico to the United States on the obesity status of children who remain in Mexico. Theory suggests that increased liquidity as well as changing time allocations resulting from migration may influence obesity outcomes. Natural disasters are used as an identification strategy. Results suggest that older boys in urban areas are more likely to become obese when either a male or female migrates from the household, while girls in urban areas are less likely to become obese. Both changes in food expenditure patterns and time use changes after migration are likely pathways that affect childhood obesity. While there are some changes in food expenditures, we find more importantly that urban girls engage in more housework and screen time after migration, whereas urban teen boys do not substitute for adult work as much as girls. These changes in strenuous activities, particularly for girls, likely explain the differential effect that migration has on boys’ and girls’ obesity outcomes in Mexico.     

Formal school or Koranic school? Determinants of school type choice in Senegal

This paper uses data from a novel household survey from the northernmost region of Senegal, Saint-Louis, in order to jointly analyse enrolment in formal and Koranic schools. The data-set includes detailed information on the education and current enrolment status of all household members. In the sample, 20% of children aged 6–14 are not enrolled in any type of school, while the majority (43%) are enrolled in both a formal and a Koranic school. Multinomial logit techniques are employed to jointly analyse enrolment in formal and Koranic schools. Specifically, these models allow for the possibility that a child combines formal and Koranic schooling. Results indicate that younger children and boys seem to favour Koranic schools, while older children and girls are more likely to attend a formal school. These results contribute towards explaining gender equality in Senegalese primary education that stands in sharp contrast to a general disadvantage of girls in other West African countries.     

Agricultural technology adoption and child nutrition enhancement: improved maize varieties in rural Ethiopia

Adoption of improved crop varieties can lead to multiple benefits to farm households, including increased productivity, incomes, and food consumption. However, possible impacts of adoption on child nutrition outcomes are rarely explored in the literature. This article helps bridge this gap through an impact assessment of the adoption of improved maize varieties (IMVs) on child nutrition outcomes using a recent household survey from rural Ethiopia. The conceptual linkage between IMV adoption and child nutrition is first established using an agricultural household model. Instrumental variable estimation suggests the overall impacts of adoption on child height‐for‐age and weight‐for‐age z‐scores to be positive and significant. Quantile instrumental variable regressions further reveal that such impacts are largest among children with poorest nutrition outcomes. Finally, by combining a decomposition procedure with system of equations estimation, it is found that the increase in own‐produced maize consumption is the major channel through which IMV adoption affects child nutrition.     

In the wake of conflict: the long-term effect on child nutrition in Uganda

The Lord’s Resistance Army (LRA) insurgency from 1986 to 2006 is one of the longest conflicts in Uganda. This paper examines the effect of the LRA insurgency on child nutrition using the 2011 Uganda Demographic and Health Survey. The distance from each village to the border of South Sudan is used as an instrument for identifying the intensity of the conflict. We find that each conflict event in a village lowers weight-for-age z-scores and weight-for-height z-scores for children born after the conflict. We further investigate a possible heterogeneous conflict effect on child nutrition in terms of gender, region, and maternal education. Low household wealth, limited access to healthcare, and poor maternal nutrition appear to be channels through which the conflict inhibits the growth and development of children 5 years after the end of the conflict.     

Household nutrition and income impacts of using dairy technologies in mixed crop–livestock production systems

Technologies like improved breeds of dairy cows and improved forages have the potential to significantly increase dairy cow productivity and farmers’ profits in developing countries. However, adoption of such technologies has been low in Ethiopia, despite numerous efforts to disseminate the technologies in the past. Some studies argue that adoption of technologies is low because welfare effects of the technologies could be insignificant or negative to certain groups of farmers. This article employed propensity score matching and inverse probability weighting estimator with regression adjustment to examine the difference in household nutrition and income between adopters and nonadopters of dairy technologies in rural Ethiopia. We find that adoption of cross‐bred dairy cows and improved forages increases household nutrition and income. The significant household nutrition and income impact for adopters support the notion that many Ethiopian smallholders have not adopted dairy technologies because adopters and nonadopters of dairy technologies have inherent differences in welfare outcome potentials. The results suggest that interventions that enhance access to farm resources and address barriers to input and output value chains could improve adoption of dairy technologies.     

Food aid and adult nutrition in rural Ethiopia

Insight into the role of safety nets that contribute to adult nutrition is an important component to understanding the dynamics of poverty in developing countries. This article uses panel data from rural Ethiopia on individual nutritional status to test for an effect of public transfers on adult body mass index (BMI). Results show that among adult household members, male members are the primary beneficiaries of food aid as male and female aid recipients tend to invest aid receipts in male household members. These results are consistent with a theory in which additional resources are allocated to members of the household whose market returns are higher or those who engage in activities that expend higher levels of energy. For high‐asset households, female household members benefit if the aid recipient is a female. Women in low‐asset households appear to be adversely affected by aid receipts, and evidence suggests that women with little bargaining power suffer the most. The results suggest that aid receipts are useful in mitigating fluctuations in adult BMI over a short time period.     

Assessing the Impact of the ‘Decoupling’ Reform of the Common Agricultural Policy on Irish Farmers’ Off‐farm Labour Market Participation Decisions

This paper assesses the impact of the ‘decoupling’ reform of the Common Agricultural Policy on the labour allocation decisions of Irish farmers. The agricultural household decision‐making model provides the conceptual and theoretical framework to examine the interaction between government subsidies and farmers’ time allocation decisions. The relationship postulated is that ‘decoupling’ of agricultural support from production would probably result in a decline in the return to farm labour but it would also lead to an increase in household wealth. The effect of these factors on how farmers allocate their time is tested empirically using labour participation and labour supply models. The models developed are sufficiently general for application elsewhere. The main findings for the Irish situation are that the decoupling of direct payments is likely to increase the probability of farmers participating in the off‐farm employment market and that the amount of time allocated to off‐farm work will increase.     

Context matters: Oil palm production and women's dietary diversity in the tropical forest of Cameroon

Oil palm is one of the most rapidly expanding food and cash crops in many tropical regions with significant environmental implications, but also economic gains. Previous analyses have established that this expansion is associated with changing gender roles and time allocation for women. Time allocation is an important determinant of maternal and child nutrition as well as well-being. We use a rich farm household survey from a native oil palm production hotspot, Cameroon, to examine the associations between oil palm production and women's dietary diversity. Using different estimation and identification strategies with some sensitivity checks, we show that oil palm is associated with lower dietary diversity for women, measured as the minimum dietary diversity for women and the minimum adequacy diversity diet. We explore heterogeneity in the various food groups consumed by women and show that oil palm production is associated with lower consumption of mainly pulses, fruits and vegetables. These findings contrast with the literature that has established some positive dietary diversity implications of oil palm expansion in Southeast Asia. We carefully discuss these findings and argue that context matters and may explain these differences. Particularly, we show that oil palm production is negatively associated with farm production diversity in Cameroon. Notwithstanding, we also confirm previous findings that highlight that oil palm production is associated with higher income. These insights add to the debate on the implications of oil palm expansion in tropical environments. Moreover, they can guide policy in designing more tailored interventions that address nutrition issues and improve rural development.     

Gender norms and intrahousehold allocation of labor in Mozambique: A CGE application to household and agricultural economics

We model intrahousehold dynamics in two rural provinces of Mozambique through the lens of computable general equilibrium (CGE) methods. The main features of our modeling framework are as follows: (a) a household social accounting matrix that captures allocation of labor and resources, and transfers among household members; (b) the explicit use of social norms in labor allocation across gender; (c) a mechanism that links agricultural production to time poverty; (d) identification of leisure as a commodity that is being produced. Simulation results and sensitivity analyses show how social norms interact with the allocation of labor and resources at the household level to impact farm production or limit the gains from technological improvements.     

Analyzing the women’s empowerment and food security nexus in rural areas of Azad Jammu & Kashmir,Pakistan: By giving consideration to sense of land entitlement and infrastructural facilities

A rich body of literature exists for explaining the role women play in ensuring their household’s food security; however, as far as their own food security is concerned, little attention has been given. Therefore, this research collects evidence on the relationship between women’s empowerment and their own food security (access) in the rural areas of Azad Jammu & Kashmir (AJK). Data were collected from the households of 600 rural women. The results provide insights that the domains of legal rights, information and communication technologies (ICTs), social support and familial rights, can be a significant pathway for enhancing the food security of women as more bargaining power of women over the utilization of resources could result in a good quality of food choices and more expense on food items due to these rights. Besides, understanding food insecurity also requires considering gender norms as in this study, the infrastructural facilities and sense of land entitlement provide unexpected non-significant results. Though women help in the mounting necessities of their families, they are unable to enhance the food requirements for themselves due to restricted mobility and less economic opportunities. This is mainly due to the poor infrastructure, and more importantly, the lack of access to resources, especially land, because of lack of knowledge and self-confidence. Notably, the fear of conflict and domestic violence may also impede women from fighting for their rights, which results in poor access to food. Hence, by understanding the household makeup from women’s perspectives and customs, the findings from this study can help and guide policymakers in developing more appropriate strategies to improve the food security of women.     

Accounting for the Gender Technology Gap Amongst Smallholder Rice Farmers in Northern Ghana

Narrowing the gender technology gap in agricultural production has become a critical policy issue in sub‐Saharan Africa. A better understanding of the gender technology gap is essential for policy formulation and programme planning to ensure equity in resource allocation, and household‐level food security in low and middle income countries, such as Ghana. We employ a metafrontier approach to analyse the differences in the efficiency of male and female farmers, recognising the endogeneity of some of the variables in the inefficiency effects model, in particular the credit constraints of the rice farmers under study. Our findings show that while the rice farms themselves are very similar, average yields for male managed farms tend to be significantly higher than female managed farms reflecting higher seeding and fertiliser application rates on male managed farms. However, there is no significant difference between the genders in either land used for rice or total output per farm household. We find some evidence that relative to the metafrontier, male managed farms are less efficient than female managed farms. The results further show gender technology gap amongst the smallholder rice farmers with females’ technology gap ratio being significantly greater than that of males, with females operating on a production frontier closer to the metafrontier. Policies that provide females more access to productive resources and other agricultural services could assist in the generation of relatively higher output.     

Economies of Scale and the Demand for Food in Switzerland: Parametric and Non‐Parametric Analysis

This paper examines the role of household public goods arising from co‐residence and economies of scale in the allocation of household expenditure. Using both parametric and non‐parametric methods, the paper tests the theoretical prediction that in the presence of shared public goods, larger households should have higher per capita consumption of private goods like food, provided that they do not substitute too much towards the effectively cheaper public good. The results indicate that, at constant per capita total expenditure, the per capita demand for food declines with household size. No evidence is found in favour of the hypothesis that the endogeneity of male and female hours of work in the labour force could be responsible for this anomaly. However, an examination of the role of direct economies of scale in explaining this negative relationship yielded a negative relationship between household size and quality adjusted unit values, suggesting that the effects of direct economies of scale dominate those generated by public goods.     

Smarter through social protection? Evaluating the impact of Ethiopia’s safety-net on child cognitive abilities

Ethiopia’s productive safety net is the second largest Social Protection Program in sub-Saharan Africa and has been rolled out to almost 10 million beneficiaries since 2005; its effects are therefore of general interest. We provide the first estimates of its impact on children’s cognitive abilities. To identify impacts of this program, we exploit four rounds of data on a cohort of children surveyed repeatedly between 2002 and 2013. We find a small but significant positive effect of the programme on both numeracy skills and vocabulary. This is driven mainly by children in households that had graduated (left) the programme just before 2013. We argue that this is at least partially related to time allocation: graduates of the programme spent more time in school than continuing beneficiaries. We also find evidence that the maths (though not language) improvement is more pronounced for boys.

Home gardens,household nutrition and income in rural farm households in Odisha,India

Home gardens have been an integral part of the recent food-based interventions aimed at stimulating changes in dietary patterns and improving nutrition. However, evidence of their effects on food security, dietary quality, child anthropometry and incomes is limited, particularly among vulnerable populations groups. Using panel data from a sample of approximately 1900 households from vulnerable population groups in Odisha, India, difference-in-differences and other econometric techniques, we analyse the effects of home gardens on food security, dietary quality, child anthropometry and income. On average, home gardens contribute to better household food security, higher dietary quality of men and women but do not contribute to higher children's dietary quality and anthropometry. Also, home gardens increase monthly per adult equivalent incomes by 37% and reduce the prevalence of poverty by 11.7 percentage points. Quantile regression results suggest that home gardens enhance food security and incomes in all quantiles, but richer farmers benefit more than poorer farmers. Overall, home gardens can enhance household food security, dietary quality of men and women, and income gains among vulnerable farming population groups, but they may not suffice to improve child dietary quality and anthropometry.     

Making community forest management work in northern Vietnam by pioneering participatory action

Transfer of land-use rights from the state to individual households and groups of households to encourage community forest management (CFM) and use of forest resources for livelihood improvement, has been in place in Vietnam since the 1990s. However, to date there has been no evidence of allocation to groups of households as community entities with joint ownership. This paper examines the success of processes tested in four villages in mountainous northern Vietnam to officially secure joint ownership of and exclusive rights to community forest land. After four years, implementation of CFM led to enhanced equality and distribution of benefits, and better protection of forest resources. Household income remained largely unchanged, in part because of loss of income from activities which were now illegal, but also because it was too early for benefits to flow from new forestry initiatives. Active participation of and between village communities in land-use planning and allocation, and a willingness to compromise, particularly on the position of land boundaries, were essential elements to ensuring equity in the distribution of benefits. Lack of enabling processes and experience in the implementation of government policies mean that further support for village communities is needed to fully realize the benefits from joint management of the allocated community forest.     

Climate,weather and child health in Burkina Faso

It is now clear that anthropogenic climate change is having a negative impact on human health. In this paper, we provide the first comprehensive assessment of the impact of climatic stressors on child health in Burkina Faso. We undertake a rigorous empirical analysis of the impact of climate and weather shocks on mortality, stunting (height-for-age Z-score) and wasting (weight-for-age Z-score), using Demographic and Health Surveys, combined with high-resolution meteorological data, controlling for household and individual covariates. We find robust evidence that both lifetime and short-term exposure to high temperatures and droughts have a negative impact on child health, as do increased temperature anomalies during crop seasons, suggesting a link between climate and health through domestic food production. Income and household wealth, access to electricity, sanitation and a health facility for childbirth negate some adverse impacts of climate change. Combining our econometric estimates with updated CMIP6 scenarios, we compute policy-relevant projections of future child health. Our results show that future warming is projected to significantly increase child mortality, and share of underweight and stunted children, in all but the Paris Agreement scenario. Given the links between health, a key element of human capital, and economic growth, our findings and projections provide yet more evidence of the importance of a rapid reduction in global emissions combined with adaptation funding, if lower-income countries are to achieve poverty reduction and increasing prosperity.     

Partnerships and production: Agriculture and polygyny in Tanzanian households

Women make important contributions to household food production in sub‐Saharan Africa. Women's agricultural productivity is often reduced, however, by inefficient intrahousehold allocation of agricultural resources. Complex marital structures found in polygynous households may complicate resource allocation. Using three waves of the Tanzania Living Standards Measurement Survey–Integrated Survey on Agriculture, we measure the effect of the marital structure, wife position, and plot management on agricultural productivity and input allocations. We find evidence of cooperation within polygynous households. Plots managed by husbands and wives in polygynous households produce more valuable crops, have higher yields, and are more likely to use fertilizer than their monogamous counterparts. Within polygynous households, we observe that plots jointly managed by husbands, first wives, and second wives (together) have significantly more family labor than plots managed by husbands and first wives. This result may provide evidence of different production technologies across plot managers within the same households.
