Compounding food and income insecurity in Yemen: Challenges from climate change

This paper provides a model-based assessment of local and global climate change impacts for the case of Yemen, focusing on agricultural production, household incomes and food security. Global climate change is mainly transmitted through rising world food prices. Our simulation results suggest that climate change induced price increases for food will raise agricultural GDP while decreasing real household incomes and food security. Rural non-farm households are hit hardest as they tend to be net food consumers with high food budget shares, but farm households also experience real income losses given that many of them are net buyers of food. The impacts of local climate change are less clear given the ambiguous predictions of global climate models (GCMs) with respect to future rainfall patterns in Yemen. Local climate change impacts manifest itself in long term yield changes, which differ between two alternative climate scenarios considered. Under the MIR scenario, agricultural GDP is somewhat higher than with perfect mitigation and rural incomes rise due to higher yields and lower prices for sorghum and millet. Under the CSI scenario, positive and negative yield changes cancel each other out. As a result, agricultural GDP and household incomes hardly change compared to perfect mitigation.     

Impact of off-farm income on food security and nutrition in Nigeria

While the poverty implications of off-farm income have been analyzed in different developing countries, much less is known about the impact of off-farm income on household food security and nutrition. Here, this research gap is addressed by using farm survey data from Nigeria. Econometric analyses are employed to examine the mechanisms through which off-farm income affects household calorie and micronutrient supply, dietary quality, and child anthropometry. We find that off-farm income has a positive net effect on food security and nutrition. The prevalence of child stunting, underweight, and wasting is lower in households with off-farm income than in households without. Using a structural model, we also show that off-farm income contributes to higher food production and farm income by easing capital constraints, thus improving household welfare in multiple ways.     

Land rights,gender equality and household food security: Exploring the conceptual links in the case of India

This paper seeks to critically examine the conceptual linkages between the issue of land rights for women, with household food security on the one hand and gender equality on the other. After a brief analysis of shifts in both international and national policy discourse and practice in terms of control over land as vital for food security, it seeks to analyse the implications of this for gender relations. The paper argues that in a context of diversified rural livelihoods, the contribution of agricultural production to household subsistence has been declining. This trend has been reinforced by a decline in public investment, stagnant growth and fluctuating prices for agricultural products. Men have been able to access the better paid, non-farm jobs, while leaving women behind to manage agricultural production. The renewed link between production and food security in agricultural policy has however meant allowing men not to have responsibility for household food security. While a right to land for women is a positive development, it appears also to be leading to an enhancement of work burdens, without much change in terms of status or decision-making authority.     

Addressing food security in Africa via multiple livelihood strategies of women farmers

Because food insecurity is primarily a problem of low household incomes and poverty, and not just inadequate food production, projects and programs for food insecure African farmers which aim at increasing production of subsistence crops may be ineffective. Instead, government should look for ways to improve returns to farmers' resources in a broader context, which may include expanded opportunities for non-farm microenterprises and agricultural labor. This has been the conventional wisdom since the writings of Amartya Sen. Still unclear, however, are the implications of his thinking for the roles of African women farmers who are traditionally the food-crop producers in Africa and are often food insecure. Immediate expansion of income-earning activities such as cash cropping and non-farm microenterprises may not be possible for women in male headed households in many African societies where cash income is seen as part of the male domain. In addition, women farmers may need a long adjustment period to diversify their income sources fully because most African countries are at the early stages of structural transformation. Different developmental interventions, both in policy and in technology, are therefore needed to address food security and economic transformations in Africa in the short and long term.     

Impact of tissue culture banana technology on farm household income and food security in Kenya

While tissue culture (TC) technology for vegetative plant propagation is gradually gaining in importance in Africa, rigorous assessment of broader welfare effects for adopting smallholder farm households is lacking. Using survey data and accounting for selection bias in technology adoption, we analyze the impact of TC banana technology on household income and food security in Kenya. To assess food security outcomes, we employ the Household Food Insecurity Access Scale (HFIAS) – a tool that has not been used for impact assessment before. Estimates of treatment-effects models show that TC banana adoption, combined with improved crop management, causes considerable increases in farm and household income. Technology adoption also reduces relative food insecurity in a significant way. These results indicate that TC technology can be welfare enhancing for adopting farm households. Adoption should be further promoted through upscaling appropriate technology delivery systems.     

The impact of a food security program on household food consumption in Northwestern Ethiopia: A matching estimator approach

With the financial support from various development partners, Ethiopia has designed and implemented several programs to improve household food security. Yet, food insecurity is still a major challenge to several millions of people in the country and it is questionable whether the different food security programs implemented over the past years have been successful. Using a propensity score matching method to control for pre-intervention differences, this study examined the impact on household food calorie intake of an integrated food security program (IFSP), which had been implemented in Northwestern Ethiopia by two non-governmental organizations as a case study. The estimated results provide evidence that IFSP has a positive and statistically significant effect on food calorie intake. In particular, IFSP has raised physical food calorie intake by 30% among the beneficiary households. However, we also found that IFSP has differential impact depending on family size, landownership and gender of head of household. Overall, the paper provides evidence that supporting integrated food security programs is important to improve food security in rural areas.     

Impact of commuting by workers on household dietary diversity in rural India

Drawing insights from the literature on transformation of rural non-farm employment, pathways from agriculture to nutrition, and linkages between migration and nutritional status of household, we seek to understand differences in dietary diversity across three mutually exclusive types of rural Indian households: where all members work in rural areas, at least one member commutes to urban areas, at least one member has no fixed place of work. Our analysis is based on a nationally representative data set from India for the year 2009–10 and we use propensity score matching methods. We find that as compared to households with no commuters, households with rural–urban commuters have higher dietary diversity; whereas households with no fixed place workers have lower dietary diversity. We also find differences in dietary diversity across households which differ by their primary source of income.     

Improving developing country food security through aquaculture development—lessons from Asia

This paper provides a framework for examining aquaculture’s linkages to food and nutritional security by elucidating key hypotheses concerning the role of aquaculture in household food and income systems in developing countries. Taking examples from developing Asia, where aquaculture showed a steady growth over the last decade, the implications of aquaculture development are examined from the standpoint of its impact on employment, income and consumption. Analysis revealed clear evidence of positive income and consumption effects of aquaculture on households. However, employment effects are still not significant. The context of targeting small-scale and subsistence-oriented farmers as a means of improving food security in the developing countries has also been analyzed by identifying key socio-economic and policy factors affecting aquaculture adoption and its impact on the poor. The paper concludes that national policies for aquaculture development will need to concurrently address the food security and poverty questions more sharply than has been done at present, by providing institutional and infrastructure support for access to resources such as land and water and to markets by poor households. Finally, more empirical evidence should be collected on the varied opportunities aquaculture would provide to improve the income, employment and food consumption levels within households.     

What explains gender differences in food insecurity?

There is a rich literature devoted to the role women play in ensuring the food security of the household and other household members. However, relatively little attention has been paid to their own food security situation. The challenge with investigating the food security of women is that most surveys collect food security data at the household level making inferences about individual-level food security difficult. Using a large international sample of individual-level data and the first global experiential measure of food insecurity, I show that women have a higher probability of being food insecure relative to men. The magnitude of the gender gap in food insecurity varies across regions and varies by the severity level of food insecurity. In the developed countries of the European Union, women are 4.7 percentage points more likely than men to experience some form of food insecurity. In the poor countries of South Asia and Sub-Saharan Africa, women are two percentage points more likely than men to be severely food insecure. Using a modification of the Blinder-Oaxaca decomposition technique, I find that gender differences in household income, educational attainment, and social networks explain the majority of the gender gap in food insecurity. However, in some regions, namely South Asia and Australia/New Zealand, gender differences in observable characteristics fail to account for gender differences in food insecurity. This analysis suggests that policies that address gender inequality in employment opportunities and educational attainment may also impact food insecurity.     

Food aid and household food security in a conflict situation: Empirical evidence from Northern Uganda

It is well-established that armed political conflict has a detrimental effect on food security and household welfare: conflict induces food insecurity by reducing own food production, access to food through the market, and various other resources to sustain healthy and productive lives. One way of mitigating these adverse effects is to provide food aid. In this study we evaluate the impact of a World Food Programme intervention on household food security and asset protection among conflict-affected households in Northern Uganda. We employ propensity score matching to estimate the average treatment effect on food expenditure, food consumption and preservation of assets using a sample of 1265 observations from a 2008 survey. Our results reveal that the operation’s system of targeting beneficiaries was effective and in accordance with programme objectives. Food aid considerably reduced food expenditure of households, suggesting that recipients were net buyers of food, and that the food aid received was effectively consumed within the household. A corresponding positive effect on non-food expenditure was not found. Our results also indicate that food aid was effective in increasing meals consumed and in avoiding distress destocking of low value assets, but, surprisingly, only for male headed households.     

Impact of off-farm labor supply on food expenditures of the farm household

Farm households diversify their income sources by working off the farm. This is a risk management strategy that is used by farm households in both developed and developing countries. Income diversification via off-farm work is associated with higher incomes and food consumption. However, little is known about the association between off-farm work and farm household food expenditures. In an effort to bridge this gap, this study attempts to assess the impact of off-farm work decisions by the operator and/or the spouse on the food expenditures of the farm household. Using a nationwide farm household survey in the United States and new econometric method, we find that the decisions of the operator and/or the spouse to work off the farm are significantly interrelated (29%). However, these two decisions affect food expenditures in different ways. The operator’s off-farm work decision is positively related to food expenditures, while the spouse’s decision is negatively associated with expenditures on food by the farm household.     

Determinants of income diversification amongst rural households in Southern Mali

Household-level panel data from a representative sample of rural households in Southern Mali describing the different sources of household income are used to examine the determinants of income diversification. A conditional fixed effects logit model is employed in the analysis to control for household-specific effects. We find evidence that poorer households have fewer opportunities in non-cropping activities such as livestock rearing and non-farm work, and hence less diversified incomes. This appears to reflect their relative lack of capital, which makes it difficult for them to diversify away from subsistence agriculture. The results also indicate that households in remote areas are less likely to participate in the non-cropping sector than their counterparts closer to local markets, while households with educated heads are more likely to participate in the non-farm sector than those with illiterate heads. The significance of entry-constraints in explaining portfolio diversification suggests that the role of government in making assets — as well as improved infrastructure — available to poorer households is still essential in promoting income diversification.     

The relationship between household food waste and food security in Tehran city: The role of urban women in household management

Food loss and waste are some of the most urgent social, economic and environmental issues affecting our planet's sustainability, and it has a direct and indirect impact on food security. Food security is a strategic development issue in Iran. This study aims to investigate the overall prevalence and factors affecting household food security with a novel approach to analyze the relationship between food waste and food security in Tehran city. This study applied the Household Food Insecurity Access Scale (HFIAS) for assessing food insecurity and logistic regression modeling. It was found that 64.2 percent of the households are food secure in Tehran. Results have shown that food waste has a significant negative effect on the food security of households, while marital status, family income, food storage, education and housing asset of family indicated positive significant effects on the food security of households. The results revealed most food waste is related to edible food waste such as bread, cooked rice, cooked pasta, which implies that the reduction of it can contribute to improving food security. In light of the major findings of this study, it is concluded that food waste control can decrease the food insecurity of urban Iranian households. This study is the first attempt to conceptualize and provide empirical evidence that food waste reduction increases food security A significant implication that emerges from this study is that food waste control programs could enhance food security in urban households.     

Food in sub-Saharan Africa : Trends and policy challenges for the 1990s

The food situation in Africa can be expected to become increasingly serious as the end of the century approaches. The gap between domestic supply and food needs in rapidly widening. Yield-increasing technology becomes essential in view of land scarcity in high-potential areas and sustainability problems in marginal zones. The concern of governments for food self-sufficiency, however, must not divert attention from the primary objective of household food security, which is essentially a question of households' real income. Accelerated rural growth and improved rural health and sanitation services accessible to the poor are central elements for household food security improvement.     

Household history,SNAP participation,and food insecurity

Food security in an important public policy issue. In 2015, approximately 1 in 8 U.S. households experienced food insecurity at some point in the year. Low-income families are at higher risk for food insecurity than other families, and these families may also face higher levels of disruption (e.g., moves, loss of income, or individuals entering or leaving the household) than other families. I use data from the Survey of Income and Program Participation to explore the relationship between food insecurity, the household’s history during the previous year, and SNAP participation. The results indicate that a number of aspects of the household’s recent experience including negative income shocks, moves, and both increases and decreases in household size increase the probability of being food insecure while SNAP participation is estimated to reduce the probability of being food insecure.     

Consumer demand for food diversity: evidence for Germany

Whereas a large number of empirical studies have been devoted to analysing consumer demand for specific products, much less attention has been paid to the household’s demand for product variety (the number of different products consumed in a specific time period). This paper analyses consumer demand for food variety in Germany. The econometric analysis of 4632 households suggests that variety significantly increases with income and the number of children aged between 7 and 17 years and is significantly higher if the family lives in larger cities in East Germany, and the housekeeping person is not additionally working full-time. A single male household consumes a significantly smaller number of different food products. The significant (and positive) impact of household income on food variety is in line with the hypothesis that consumption evolves along a hierarchical order as income increases.     

Non-farm income,gender, and inequality: evidence from rural Ghana and Uganda

This paper examines how the distribution of earnings in rural Ghana and Uganda differs by income type and by gender. We find that non-farm earnings contribute to rising inequality, but that lower income groups also benefit due to strong overall growth in non-farm earnings. The inequality-inducing effect is driven by self-employment income; wage income, on the other hand, reduces inequality. The tendency of non-farm income to contribute to inequality is greater among female-headed households for whom self-employment is important and non-farm opportunities more constrained. Determinants of non-farm income are estimated and appear to be strongly related to location, education, age, and distance to market. Estimates of the linkages to agriculture in Ghana are weaker than expected, showing the non-farm sector to be functioning more as an alternative activity to agriculture than as a complement.     

Non-agricultural earnings in peri-urban areas of Tanzania: evidence from household survey data

This study draws on purposive survey data of approximately 600 households in peri-urban Tanzania to describe the degree and nature of non-farm diversification in these settings. With the exception of relatively dynamic cities such as Dar es Salaam and Arusha, overall non-farm incomes shares are not unambiguously higher than in rural areas as a whole. Non-farm income shares rise sharply and monotonically with quintiles defined in terms of per capita food consumption. In that sense the sector appears to offer an important route out of poverty. The evidence suggests that education, and access to infrastructure, are important determinants of non-farm incomes in peri-urban areas. Women appear to be poorly placed vis à vis the non-farm sector, even after controlling for education, age and other characteristics. Kinship and tribal affinities, and time devoted to communal activities, appear to deter entrepreneurial activity and non-farm employment, but trust in officials and public servants and strong heterogeneous village associations, are important in stimulating non-farm activity.     

Assessing the impact of improved agricultural technologies on household income in rural Mozambique

In many areas of Africa, rural livelihoods depend heavily on subsistence farming. Using improved agricultural technologies can increase productivity in smallholder agriculture and thus raise household income and reduce poverty. Data from a nationally representative rural household survey from 2005 is used to assess the impact of four technologies – improved maize seeds, improved granaries, tractor mechanization, and animal traction – on household income in Mozambique. To ensure the robustness of the results, three econometric approaches were used: the doubly-robust estimator, sub-classification and regression, and matching and regression. The results show that, overall, using an improved technology did not have a statistically significant impact on household income. This may be associated with a widespread drought that occurred in 2005. Despite drought, distinguishing between households based on propensity score quintiles revealed that using improved technologies, especially improved maize seeds and tractors, significantly increased the income of those households who had better market access. Thus, to allow households to benefit from the use of improved technologies, policy makers need to reduce structural impediments to market participation by ensuring adequate road infrastructure and enabling access to markets.     

The dynamics of livelihood diversification in post-famine Ethiopia

Based on data for almost 300 households this paper explores associations among income diversification, household perceptions of livelihood risks, and changes in consumption outcomes across two points in time in post-famine Ethiopia. Four key questions are addressed: i) To what extent did households emerging from the famine period with relatively higher income and calorie consumption levels also have a more diversified income base?; ii) Was higher income diversification in 1989 associated with higher income and consumption levels by 1994?; iii) Which households increased their share of income from non-cropping activities most during the inter-survey years?; and iv) Did household heads perceive a lack of non-farm income activities to be an important risk factor in famine vulnerability? We find that wealthier households tended to have more diversified income streams; those initially more diversified subsequently experienced a relatively greater increase in both income and calorie intake; households with a greater concentration of assets were more likely to fall in their relative outcome ranking (as were female-headed households); and, initially less diversified households subsequently realized greater gains in income diversification. We also find suggestive evidence that personal perceptions of risk factors guided subsequent diversification decisions.
