Mopane worm (<Emphasis Type="Italic">Imbrasia belina</Emphasis>) and rural household food security in Limpopo province,South Africa

Rural households in South Africa are vulnerable to food and income adversity. As a result, they adopt a range of livelihoods strategies, including consumption and trade of woodland resources to improve their living standards. Mopane worms (caterpillars of the Emperor Moth Imbrasia belina) have been identified as important to rural livelihoods, as an alternative land-use option as well as in fulfilling an important food security function. Whilst mopane worms may contribute to food security, this safety-net function needs more critical and quantitative investigation. This study examined the relationship between mopane worm consumption and household’s food security in the Limpopo Province, South Africa using the Household Food Insecurity Access Scale (HFIAS) and the Tobit regression model based on a household survey of 120 respondents. The result from HFIAS showed that about 52 % of the households were severely food insecure, while others were either mildly or moderately food insecure. Only 16 % of the households were food secure. The Tobit regression model estimates show that proxy variables (i.e. income from mopane worm trade and the frequency of mopane worm consumption) measuring the contribution of mopane worms to rural household food security are statistically significant factors influencing household food insecurity in the study area. Implications for policy are discussed.     

Adaptation to climate change and the impacts on household food security among rural farmers in uMzinyathi District of Kwazulu-Natal,South Africa

It is anticipated that smallholder subsistence farmers will face severe negative impacts from climate change, with household food security being seriously affected. This paper examines the methods of adaptation to climate change used by smallholder farmers and their impacts on household food security. The necessity to adapt to climate change is caused by a combination of sensitivity and exposure and the success in doing so depends on adaptive capacity. Household food security was determined using the Household Food Insecurity Access Scale (HFIAS). Of the surveyed households, 95 % were aware that climate is changing and expected severe impacts on their crop production systems. Households undertake crop and soil management practices in order to respond to the changing climate. About 83 % of households anticipated that they would alter their livelihoods systems in response to climate change, with 59 % of households indicating that government grants would play an important role in this. Of those assessed, 97 % were severely food insecure and the remaining 3 % were moderately food insecure. Householders were worried about the negative impacts of climate change which included droughts, floods and soil erosion. Householders who were vulnerable to climate change recorded high levels of food insecurity. Decline in prices of farm products, increases in costs of farm inputs and anxiety over occurrence of livestock diseases exacerbated household food insecurity. Information will play a critical role in mitigating the impacts of climate change on household food security but farmers should also be assisted with appropriate input packages, such as seeds and fertilizers that can help them adapt effectively.     

Food insecurity in urban poor households in Mumbai, India

India ranks 66th of 88 countries in the Global Hunger Index and has a quarter of the world??s hungry. Food security status of 377 million inhabitants of India??s urban areas, of which one-fourth live in extreme poverty, is poorly documented. The purpose of this study was to determine (a) the extent of food insecurity among households in urban slums, (b) to quantitatively assess their subjective experiences related to food insecurity and (c) to identify sub-groups among the urban poor that are vulnerable to food insecurity. A cross-sectional, interviewer-administered survey of adult female respondents from 283 households, selected using two-stage cluster sampling, was conducted in slums across three municipal wards in the city of Mumbai. Food insecurity, as measured by the Household Food Insecurity Access Scale (HFIAS), was found in a large number of households in the urban slums of Mumbai; 59.7?% (n?=?169) households were categorized as severely food-insecure, 16.6?% (n?=?47) as mildly to moderately food-insecure, and 23.7?% (n?=?67) as food-secure. Further analysis revealed that severe food insecurity was significantly associated with lower monthly household income and other socioeconomic status measures such as lower household monthly per capita income, lower rank in the standard of living index (SLI) and less monthly per capita expense on food items. Households where the woman was the primary income-earner and contributed the largest share to the monthly household income, and was older, less educated, with less media use or access were more likely to experience severe food insecurity. Although corrective steps at the household level such as livelihood security schemes and income generation programs are necessary, they will not be sufficient to eliminate this problem; state intervention is required in order to assure food security for the urban poor. The Government of India has drafted a Food Security Bill; but the criteria for determining which households are vulnerable and deserving are still being debated. The findings of this study highlight the urgency of corrective action and also provide pointers for the identification of vulnerable or priority sub-groups. Food security policies and programs have to be implemented immediately and effectively in order to ensure that subsidies and food items are allocated to the households of the vulnerable urban poor.     

The effect of education on household food security in two informal urban settlements in Kenya: a longitudinal analysis

Poverty and food insecurity continue to feature prominently in the global agenda, with particularly close attention being paid to the determinants of food insecurity. However, the effect of education is mixed and remains understudied in low income countries. Using longitudinal data collected between 2007 and 2012 in Kenya, we investigated the effect of household education attainment on food security among poor urban households. Household food security was constructed from a set of four key items while education was the average years of schooling for individuals aged 18 years and above in a household. To determine the association between education attainment and food security, we fitted a random effects generalised ordered probit model. The prevalence of severe food insecurity ranged from 49 % in 2008 to 35 % in 2012. The ordered probit results showed a significant effect of education on food security. The probability of being food insecure decreased by 0.019 for a unit increase in the average years of schooling for a given household. The effect of education, remained significant even after controlling for household wealth index, a more proximate determinant of food security in a cash-based economy such as the urban slums. The findings highlight the need to focus on the food security status of the urban poor. Specifically, results suggest the need for programs aimed at reducing food insecurity among the urban poor and enhancing household livelihoods. In addition, investment in the education of the slum households may, in the long term, contribute to reduction in the prevalence of food insecurity.     

Impact of a participatory agroecological development project on household wealth and food security in Malawi

This paper presents the impacts of a participatory agroecological development project on food security and wealth levels. The Malawi Farmer to Farmer Agroecology project (MAFFA) encourages farmer experimentation, community involvement and farmer-to-farmer teaching on agroecology, nutrition and gender equity. Recent international assessments of agriculture have highlighted the urgent need for changes in farming practices in Sub-Saharan Africa, due to land degradation, high levels of food insecurity and anticipated climate change impacts. Agroecological approaches have shown great potential to address these multiple needs. Using a longitudinal panel survey data and propensity score matching to account for selection bias in project participation, we analyzed the impact of the project on household income and food security in Malawi in 2012 (Wave 1 = 1200 households) and in 2014 (Wave 2 = 1000 households). We used the Household Food Insecurity Access Scale (HFIAS) for impact evaluation. Estimates of average treatment-effects using difference in difference methods showed that participating in MAFFA has led to a significant increase in household wealth (β = 3.54, p = 0.01) and a large reduction in food insecurity (β = ?3.21, p = 0.01) compared to non-participants, after 2 years, even after accounting for covariates and selection bias. These results indicate that agroecological methods combined with farmer led knowledge exchanges can be welfare enhancing, both in terms of food security and in terms of income for family farm households. Agroecological approaches should be promoted through upscaling of farmer-to-farmer knowledge exchanges, community involvement and attention to nutrition and social equity to enhance farmer learning and household welfare benefits.     

Energy and nutrient supply according to food insecurity severity among Mexican households

Studies from Latin America have shown that food insecurity reduces dietary diversity. However, dietary diversity measures do not account for the energy and nutrient supply in households. The objective of our study was to know whether there are differences in food, energy and nutrients supplies in Mexican households according to their food insecurity level. We analyzed the database of the National Household Income and Expenditure Survey performed in Mexico in 2014. The modified Latin-American and Caribbean Food Security Scale was used to determine the existence of household food security or insecurity. Participants registered foods and beverages available at their homes during the previous week. The supply of energy and nutrients was estimated using Mexican and American food composition references. Mexican food secure households had greater supply of healthy (e.g., fresh fruits and vegetables, fish and seafood, and fresh meats) and unhealthy (e.g., processed meats, fries, sugar-sweetened beverages, desserts, and alcoholic beverages) foods. By contrast, food insecure households rely on cheap staple food (e.g. maize, rice, pulses, eggs, and sugar). There was a linear relationship between the energy density and severity of food insecurity. Households with mild and moderate food insecurity had greater total energy supplies than households with food security and severe food insecurity. Food insecure households had greater supplies of carbohydrates, cholesterol, iron, and magnesium, but lower supplies of protein, fat, vitamin C, vitamin A, potassium, calcium, and sodium. Most of the results suggest that food insecure households are exposed mostly to negative aspects of the nutrition transition because they have greater access to energy and lower availability of some micronutrients.     

Food insecurity and coping strategies in South-West Nigeria

Food insecurity and coping strategies in Ado-Ekiti, Ekiti State in the south-western part of Nigeria were studied by means of a multistage sampling technique. Data were collected from 80 households, consisting of 321 members, with the aid of a well-structured questionnaire, and were analysed using a Food Insecurity Index. The overall incidence of food insecurity was 58.8 % while the depth of food insecurity, expressed as the average percent increase in calories required to meet the recommended daily requirement, was 19.5 %. Thus, the study confirmed the widespread existence of household food insecurity but with mild severity. Food insecurity indices declined with higher levels of income and educational attainment but increased with household size and number of dependants. Incidence of food insecurity was slightly higher among female headed than male headed households but the depth and severity were lower. Eating less expensive and less preferred food and reducing portion sizes were the three most common coping strategies for combating short-term food shortages. Policies that would enhance income earning capacity of household members and their access to higher education, well-focused gender specific interventions and promotion of backyard farming are advocated.     

Experiential household food insecurity in an urban underserved slum of North India

One-third of India’s urban population resides in extreme poverty, in slums and squatters. Food insecurity remains a visible reality among this segment. Yet, it is scarcely documented. This paper describes levels and determinants of experiential household food insecurity (HFI) in an underserved urban slum of Delhi (India) and reports the internal validity and reliability of the measure used to assess experiential HFI. A four-item scale was adapted from the U.S. six-item short-form food security scale and was administered in Hindi through household interviews with 410 female adults. Association of HFI with household economic and socio-demographic characteristics were examined using multiple logistic regression. Cronbach’s alpha and Rasch-model-based item fit statistics were used to assess reliability and internal validity. Fifty-one percent of households were food insecure. Significant HFI predictors were unemployed to employed family members’ ratio of > 3:1 (Odds Ratio 2.1, Confidence Interval 1.2 – 3.4) and low household standard of living (OR 4.9, C.I. 2.7 – 8.9). Cronbach’s alpha was 0.8. Item severities as estimated under Rasch model assumptions spanned 9.7 logits. Item infit statistics (0.77 – 1.07) indicated that the Rasch model fit the data well. Item outfit statistics suggested that one item was inconsistently understood by a small proportion of respondents. For improving HFI among the urban poor, in addition to improving behaviors/entitlement access, programs should consider linkage of urban poor to existing employment schemes, upgrading of their skills and linkage to potential employers. The adapted scale was reliable and easy to administer. However, being a subjective assessment, its sensitivity to social expectation and its association with nutrition security require examination.     

Food insecurity in canadian adults receiving diabetes care

Purpose: The prevalence of adult-level household food insecurity was examined among clients receiving outpatient diabetes health care services. Methods: Participants were adults diagnosed with diabetes mellitus, who attended individual counselling sessions at Calgary's main clinic from January to April 2010. Clinicians were trained to administer the Household Food Security Survey Module (HFSSM), and did so with clients' assent during their scheduled sessions. Results: The prevalence of adult-level household food insecurity among 314 respondents was 15.0% (95% confidence interval [CI], 11.2 to 19.4); 6.7% (95% CI, 4.2 to 10.0) of clinic attendees were categorized as severely food insecure. The comparable rates obtained in Alberta in 2007 using the same instrument (HFSSM) were 5.6% and 1.2%, respectively. Conclusions: Household food insecurity rates among individuals with diabetes in active care are higher than rates reported in Canadian population surveys. Severe food insecurity, indicating reduced food intake and disrupted eating patterns, may affect this population's ability to follow a pattern of healthy eating necessary for effective diabetes management. This study reinforces the importance of assessing clients' inability to access food because of financial constraints, and indicates that screening with a validated measure may facilitate identification of clients at risk.     

Vulnerability in crisis: urban household food insecurity in Epworth,Harare, Zimbabwe

Much of the contemporary literature on food security has focused on the rural sector. However, within the current context of high demographic growth, rapid urbanization and rising urban poverty which characterizes much of Sub-Saharan Africa, urban food insecurity cannot continue to be ignored. This study therefore examines the vulnerability of poor households to food insecurity in the challenging urban environment of Harare in Zimbabwe, an acute example of a city (and country) ‘in crisis’. Findings from qualitative and quantitative research demonstrate severe food insecurity characterized by critical food shortages and the consumption of narrower diets among poor households in the city. Household vulnerability to food insecurity stemmed from a range of factors, including: high levels of unemployment and poverty; high dependency ratios; low levels of house ownership; hyperinflation; skyrocketing food prices; and the general collapse of the formal food system. Vulnerability to food insecurity was further exacerbated by a prolonged adverse socio-political climate that undermined national economic recovery and reduced the livelihood opportunities available to the urban poor. The paper concludes that in Harare, as in most urban areas of the developing world, the urban poor have become highly vulnerable to food insecurity.     

Sensitivity and specificity of a short questionnaire for food insecurity surveillance in Iran

BACKGROUND: Food insecurity is frequent in both developed and developing countries, affecting from 5% to 25% of the general population. It has considerable health impacts on the physical, social, and psychological status of individuals in communities suffering from food insecurity. OBJECTIVE: The aim of this study was to document the epidemiologic features of food insecurity in the northwest region of Iran and to evaluate the sensitivity and specificity of a short-form (six items) questionnaire for screening of food insecurity in the region. METHODS: This cross-sectional study was conducted on 300 subjects (132 male and 168 female) selected randomly in the Asadabadi area of the northwest of Iran. Information on food consumption was obtained by a 24-hour food-recall questionnaire for 3 days in a week. This information was compared with the data from the Household Food Security Scale (six-item short questionnaire) to assess the applicability of this short scale for the surveillance of food insecurity. Hunger was defined as inadequate intake of energy. Hidden hunger was defined as adequate intake of energy and inadequate intake of one (or more) of four key nutrients (protein, calcium, vitamin A, and vitamin B2). RESULTS: The prevalence of hunger and hidden hunger in the area according to the 24-hour food-recall questionnaire was 26% and 42%, respectively. Only 32% of the study population was secure in terms of having access to all key nutrients. The sensitivity, specificity, and accuracy of the short questionnaire for screening for hunger in the population were 98.7%, 85.5%, and 89%, respectively; and the corresponding values for hidden hunger were 23.5%, 96.9%, and 56.3%. CONCLUSIONS: Our findings indicate that food insecurity is prevalent in the northwest of Iran. The short questionnaire (six items) may be used as a simple, low-cost, rapid, and useful tool for the screening of food insecurity and energy intake in similar areas.     

Vulnerability of smallholder rural households to food insecurity in Eastern Ethiopia

Although several empirical methodologies as to how best assess vulnerability to food insecurity have been proposed in the literature, none of these has evolved into a unanimously accepted approach. This article contributes to this literature by adapting the Vulnerability as Expected Poverty approach from poverty analysis methodology with the aim of scrutinizing factors determining household level vulnerability to food insecurity based on cross-section data collected from 277 randomly selected households in eastern Ethiopia. Vulnerability to food insecurity was strongly associated with several factors which included family size, size of cultivated landholding, soil fertility status of plots, access to irrigation, number of extension visits, use of fertilizer and improved seed. The probability that any given household??s food consumption expenditure would fall below a specified cut-off level has also been computed and vulnerable households identified. The total number of vulnerable households (111) was found to be greater than those who are currently food insecure (103). This implies that design and implementation of food security policies and strategies need to focus not only on those who are observed to be currently food insecure, but also on setting up social protection mechanisms to help prevent households from falling more deeply into food insecurity in the future.     

Internal validity of the Food Access Survey Tool in assessing household food insecurity in rural Zambia

We assessed the internal validity of the Food Access Survey Tool (FAST) using data from households (n?=?907) enrolled in an efficacy trial of biofortified maize in rural Zambia. This scale assesses food insecurity over a 6-month recall period. A Rasch partial credit model was used to evaluate item performance. Unidimensionality was assessed by principal component analysis, monotonicity was assessed by non-parametric methods, and differential item functioning (DIF) by several characteristics was assessed by cumulative ordinal logistic regression models. One item (frequency of consuming three square meals) did not fit the partial credit model. The remaining eight items fit in a primary single statistical dimension and item category severity increased monotonically with increasing severity of food insecurity. We identified statistically significant DIF in three subgroup comparisons, but effect sizes of total DIF were considered practically insignificant (<2 %). After excluding the item on “square meals,” the FAST serves as an internally valid tool to measure household food insecurity in rural Zambia.     

Indigenous peoples’ fisheries and food security: a case from northern Canada

Indigenous peoples in northern Canada (at least the off-reserve part of the population) experience food insecurity at a rate which is more than double that of all Canadian households. The Cree community of Norway House in northern Manitoba, which harvests and consumes a great deal of fish, may be an exception and may offer some lessons. The objective of the paper is to address food security through the lens of local fisheries, both commercial and subsistence, of a northern indigenous community, and to develop an integrated approach to analyze food security. The approach uses Sen’s entitlement theory and the concept of food sovereignty. This mixed-methods research study employed questionnaire surveys among on–reserve commercial and subsistence fishing households, semi-structured interviews, focus group discussions and follow-up interviews for verification. During commercial fishing seasons (spring/summer and fall), fishers and their helpers share their fish harvest extensively through their families and communal networks, reaching almost half of the total population of the community. Such extensive sharing and the continuing community-based fishery have contributed to Norway House having more than 90 % food secure households, comparable to the Canadian average. Norway House may provide an example for other northern indigenous communities regarding food insecurity through use of fish and other traditional foods. The proposed integrated approach may be useful for analyzing food security in general.     

Associations of food insecurity with body mass index among baby boomers and older adults

Increasing obesity levels portend a challenging societal healthcare issue, while the current economic crisis may foster food insecurity, characterized by limited or uncertain access to adequate food. This study examines associations among food insecurity, meeting recommendations for dietary and physical activity patterns, and body mass index (BMI) among baby boomers and older adults completing the 2010 Brazos Valley Health Survey. Subjects included 2,985 respondents (1,589 baby boomers and 1,396 older adults). Thirty-six percent of participants were obese while 15 % of participants were food insecure. Approximately 8 % of baby boomers and older adults were both food insecure and obese. Among all study participants, an increased BMI was more common among those who were ethnic minorities and had depression. An increased BMI was less common among those who met fruit/vegetable intake and physical activity recommendations. There was a positive association between food insecurity and BMI only among baby boomer and older adult females. A combined emphasis on availability of healthy foods and increased opportunities for meeting physical activity guidelines can help to counter the food insecurity-obesity connection among both baby boomer and older adult females.     

Assessing reliability,change after intervention,and performance of a water insecurity scale in rural Ethiopia

There is growing interest in the phenomenon of water insecurity, yet a relative paucity of tools to assess the occurrence and severity of water insecurity at the household level. We sought to assess the validity and reliability of a household water insecurity scale in a rural Ethiopian context. Secondary data on water insecurity from up to 1934 rural Ethiopian households that had participated in a water and sanitation intervention was analysed. Exploratory factor analysis and Cronbach’s alpha were used to assess dimensionality of the water insecurity responses and parametric and non-parametric tests used to test for differences in household water insecurity scores across household types and objective measures of household water access. Factor analysis revealed one dominant factor and the Cronbach’s alpha of the water insecurity scale was 0.94. Households with access to improved water sources, that lived close to water collection points, that did not farm, and that felt they had “enough” water all scored as significantly more water secure on the household water insecurity scale (P < 0.05). The household water insecurity scale also predicted the occurrence of diarrhea among children in the household (aOR 1.2, 95 % CI 1.08, 1.33) whereas no other measure of water access did. Finally, household water insecurity scores improved by 55 % after a water and sanitation intervention.Our results suggest the possibility of an effective water insecurity tool, which might be deployed to assess the epidemiology of water insecurity including its causes and consequences. Future research should aim to validate the tool against behavioral observations and to link shifts in water insecurity to changes in health and wellbeing.     

Evaluating the impact of improved maize varieties on food security in Rural Tanzania: Evidence from a continuous treatment approach

This paper investigates impact heterogeneity in the adoption of improved maize varieties using data from rural Tanzania. We used a generalized propensity-score matching methodology, complemented with a parametric econometric method to check the robustness of results. We found a consistent result across models, indicating that adoption increased food security, and that the impact of adoption varied with the level of adoption. On average, an increase of one acre in the area allocated to improved maize varieties reduced the probabilities of chronic and transitory food insecurity from between 0.7 and 1.2 % and between 1.1 and 1.7 %, respectively. Policies that increase maize productivity and ease farmers’ adoption constraints can ensure the allocation of more land to improved technologies and, in doing so, enhance the food security of households.     

Female-headed households and food insecurity in Brazil

The National Household Survey carried out in 2009 by Brazil??s bureau of the census contains information on a representative sample of 121,708 households. The questionnaire includes items that enable us to identify households that experience moderate and severe degrees of food insecurity. The results of logistic regression analyses support the hypothesis that the odds of food insecurity are higher among female-headed households compared to male-headed households. Net of statistical controls for region, urban residence, age, monthly per capita household income, and five indicators of the internal composition of the household, the odds of moderate and severe food insecurity are, respectively, 32?% and 16?% higher among households headed by women compared to households headed by men. Further analyses show that the likelihood of food insecurity increases with presence of young children 0?C10?years of age and older children 11?C18?years of age. The importance of intra-household characteristics is confirmed by results that show that the odds of both moderate and severe food insecurity increase with additional adult males but decrease with additional adult females. Evidence that the presence of adult females reduces food insecurity is consistent with studies of gender differences in household decision making which show that, compared to men, women??s spending patterns have a greater positive effect on the welfare of children and other members of the household. The conclusions are discussed in the context of the poverty and hunger alleviation initiatives in Brazil??s new social policy agenda.
