Resilience—the capacity that ensures adverse stressors and shocks do not have long-lasting adverse consequences—has become a key topic in both scholarly and policy debates. More recently some international organizations have proposed the use of resilience to analyze food and nutrition security. The objective of the paper is twofold: (i) analyze what the determinants of household resilience to food insecurity are and (ii) assess the role played by household resilience capacity on food security outcomes. The dataset employed in the analysis is a panel of three waves of household surveys recently collected in Tanzania and Uganda. First, we estimated the FAO’s Resilience Capacity Index (RCI), combining factor analysis and structural equation modeling. Then probit models were estimated to test whether the resilience is positively related to future food security outcomes and recovery capacity after a shock occurs. In both countries, the most important dimension contributing to household resilience was adaptive capacity, which in turn depended on the level of education and on the proportion of income earners to total household members. Furthermore, household resilience was significantly and positively related to future household food security status. Finally, households featuring a higher resilience capacity index were better equipped to absorb and adapt to shocks. 相似文献

The State of Paraiba in Northeastern Brazil ranks as the fourth poorest state in the country. The objectives of this study are to conduct the psychometric validation of the Brazilian Household Food Insecurity Scale (EBIA), to assess the household food insecurity (HFI) prevalence, and to identify the association between HFI, poverty and dietary intake in a representative sample of Paraiba’s 14 poorest municipalities (N = 4533). All municipalities included had fewer than 50,000 inhabitants. EBIA had strong internal consistency (Cronbach’s alpha = 0.93 and 0.90 in households with and without children, respectively). The percentage of affirmative responses for each item was inversely associated with household income and the item curves were parallel across socio-economic strata. Rasch modeling indicated that: a) scale items severities followed theoretical expectations, b) all items had an adequate fit to the scale confirming its unidimensionality, and c) items ‘functioned’ similarly across key subpopulation characteristics including: urban/rural; men/women; younger/older; poor/less poor; Bolsa Familia enrollment (yes/no). HFI prevalence was higher in rural than in urban areas (55.5 % vs. 49.9 %, p < 0.0005) and severe food insecurity was substantially higher in rural areas (14.0 % vs. 9.0 %, p < 0.0005). HFI severity was inversely associated with household income, positively associated with daily sugar consumption and inversely associated with daily consumption of bread and nutrient dense foods (fruits, vegetables, and dairy). In conclusion, EBIA had strong internal and external validity at the municipal level. Findings are particularly relevant for Brazil where 89.1 % of municipalities (4,957 out of 5,565 municipalities) have less than 50,000 inhabitants. 相似文献

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. 相似文献

Food aid is no longer the only, or even the dominant, response to widespread food insecurity. Donors, governments, NGOs and
recipient communities exhibit rapidly growing interest in and experimentation with cash-based alternatives, both in the form
of direct cash distribution to food insecure persons, and of local or regional purchase of food using cash provided to operational
agencies by donors. But humanitarian assistance and development communities lack a systematic, field-tested framework for
choosing among food- and/or cash-based responses to food insecurity. This paper outlines the rationale for “response analysis”
and introduces a new, field-tested, systematic approach to this emergent activity. The Market Information and Food Insecurity
Response Analysis (MIFIRA) framework provides a logically sequenced set of questions, and corresponding analytical tools to
help operational agencies anticipate the likely impact of alternative (food- and/or cash-based) responses and thereby identify
the response that best fits a given food insecurity context.

Bob Bell worked at CARE for seventeen years with the last five as Director of the Food Resource Coordination Team (FRCT) at CARE USA Headquarters in Atlanta, Georgia. Mr. Bell and his team provided support and assistance to as many as 22 CARE country offices that used U.S. Food for Peace Title II food aid in programs addressing food insecurity. Support and assistance was in the areas of program assessment, design, implementation, monitoring and evaluation as well as commodity management. CARE from the start of the Food for Peace program in 1954 through 2006 was among the top three US NGOs (generally first) receiving U.S. food aid. As Director of FRCT, he was the project manager of a USAID, Office of Food for Peace Institutional Capacity Building (ICB) Grant that focused on strengthening Title II program initiatives addressing food insecurity. As CARE shifted its organization-wide program approaches to address underlying causes of poverty in the early 2000s, CARE began to review its own uses of food aid. He played a key role in the development of CARE’s White Paper on Food Policy June 2006 that included advocacy for greater use of local/regionally purchased food and the significant decision to end the sale of food aid to generate cash (monetization) as budget support for programs by September 2009. In 2007, Mr. Bell asked Professors Barrett and Maxwell to flesh out their Decision Tree Model. The analyses generated could then be used by CARE managers to make more informed decisions on resource transfers (food and/or cash) in food security programs. The Decision Tree could also be used by donors and others to help them make better resource transfer choices. Mr. Bell worked closely with CARE’s Policy Advocacy Unit to develop CARE positions on food aid reform and developing a more comprehensive U.S. Government strategy to address hunger. Over the years, he worked very closely with USAID’s Office of Food for Peace, as well as USDA, U.S., Canadian, and European NGOs, the World Food Program, and universities and research institutions.

Addressing the challenges of global food security will benefit from the simultaneous incorporation of nutritional priorities
that contribute to the good health of populations. Inclusion of nutritional considerations, when increasing availability and
access to food, broadens the scope and objectives of agriculture and food production and thus contributes to an integrated
concept of food and nutrition security. The poor quality of food and lack of diversity in the habitual diet of many who live
in the developing world imposes enormous costs on societies in terms of ill health, lives lost, reduced economic productivity
and poor quality of life. Micronutrient deficiencies are a problem that is much greater than hunger and is a prime example
of the need to integrate both food and nutrition security. Sustainable food-based approaches to enable adequate consumption
of micronutrients include dietary diversification and biofortification. Agriculture and agricultural biotechnology not only
offer the opportunity of increasing crop yields, thereby increasing food security, but also have the potential to improve
the micronutrient content of foods, thus contributing to the achievement of both food and nutrition security. Ensuring food
and nutrition security will facilitate the attainment of the targets set for the Millennium Development Goals. 相似文献

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. 相似文献

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. 相似文献

Timor-Leste is a small, poor and predominantly-agricultural nation of less than 1 million people. Most families suffer from
chronic food insecurity practising food rationing 1–6 months of the year. The small size of Timor-Leste, its recent birth
as a nation and conflict history, together with little previous research on staple crops make it a unique crucible to test
the effect of a major post-conflict initiative of agriculture research on national food security. Research started in 2000
with the introduction of germplasm of staple crops (maize, peanut, rice, cassava and sweet potato). Replicated trials confirmed
by extensive evaluation in farmer-managed trials revealed significant yield advantages over the local cultivar in maize of
53%, in peanut of 31%, in rice of 23% and in sweet potato of 80%, accompanied by improvements in size and eating quality.
Cultivars of maize (2), peanut (1), rice (1) and sweet potato (3) were released in 2007. One year later an early adoption
study of 544 farmers involved in on-farm trials showed that 73% had re-grown new cultivars. Cultivar adoption not only increased
household food security but often produced surpluses for sale in the market—sometimes for the first time. The project is planning
to increase seed production and dissemination to move from a highly positive pilot-scale impact in six Districts to impact
food security nationally. 相似文献

PURPOSE: The degree of food insecurity and dietary intake was examined in adult Colombians who are new immigrants to Canada and use a food bank. METHODS: In-person surveys were conducted on a convenience sample of 77 adult Colombian immigrant food bank users in London, Ontario. Degree of food insecurity was measured by the Radimer/Cornell questionnaire, food intakes by 24-hour recall, sociodemographics, and questionnaires about changes in dietary patterns before and after immigration. RESULTS: Thirty-six men and 41 women participated in the study. Despite being highly educated, all respondents had experienced some form of food insecurity within the previous 30 days. The degree of food insecurity seems to be inversely associated with income and length of residency in Canada. Total daily energy intake was low, with a mean value of 1,568.3 +/- 606.0 kcal (6,217.5 +/- 2,336.4 kJ). In particular, a large proportion of participants consumed a diet low in fruits and vegetables (73%) and milk and dairy products (58%). CONCLUSIONS: Colombian immigrant food bank users new to Canada experience various degrees of food insecurity, which is associated with inadequate food intake. Interventions are needed to assist this population with adapting to society while concurrently sustaining healthy eating patterns. 相似文献

Sensitivity and specificity of a short questionnaire for food insecurity surveillance in Iran 总被引:1,自引:0,他引:1
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. 相似文献

Factors related to adoption of new agricultural technologies have been given increasing attention, especially in developing countries where such technologies offer opportunities to increase food production. One of the most immediate ways to improve food production significantly is through the adoption of high yielding varieties of food crops, but rates of adoption are often low, especially among the rural poor. In Timor-Leste, improved varieties of food crops with yield advantages across all agro-ecological zones have been introduced. However, despite yield advantages, suitability and high levels of food insecurity, discontinuance occurs and adoption rates are low. To identify factors related to adoption of the improved varieties across agro-ecological zones, binary logistic regression was performed on data collected from 1511 rural households. The results identified several factors related to adoption and showed that their impact varied across agro-ecological zones. The factor most strongly related to adoption was having a relationship to a grower of an improved variety of food crop and the closeness of this relationship. Furthermore, the following factors were related to adoption with variation across agro-ecological zones: age; education; size of farming plots; travel time between household and farming plot; involvement with the programme developing the improved varieties of food crops and participation in groups and training programmes. Overall, the findings of this study emphasize that dissemination strategies should embrace social relationships and be sensitive to agro-ecological zones. 相似文献

Vulnerability in crisis: urban household food insecurity in Epworth,Harare, Zimbabwe 总被引:1,自引:0,他引:1
Godfrey Tawodzera 《Food Security》2011,3(4):503-520
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. 相似文献

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. 相似文献

Food security has attracted widespread attention in recent years. Yet, scientists and practitioners have predominately understood food security in terms of dietary energy availability and nutrient deficiencies, rather than in terms of food security’s consequential implications for social and political violence. The present study offers the first global evaluation of the effects of food insecurity on local conflict dynamics. An economic approach is adopted to empirically evaluate the degree to which food insecurity concerns produce an independent effect on armed conflict using comprehensive geographic data. Specifically, two agricultural output measures – a geographic area’s extent of cropland and a given agricultural location’s amount of cropland per capita – are used to respectively measure the access to and availability of (i.e., the demand and supply of) food in a given region. Findings show that food insecurity measures are robustly associated with the occurrence of contemporary armed conflict. 相似文献

Timor-Leste fishers use simple fishing techniques, boats and equipment, and the fishery sector presents a unique opportunity to promote an environmentally sustainable pattern of fishery resource management. Timor-Leste has one of the highest rates of chronic malnutrition in the world, and fish could provide the needed protein, vitamins, and micronutrients. Here, I describe the models of production, distribution, and marketing of fish, and the consumption patterns of animal proteins. I discuss how ritual meat exchanges and marketing constraints influence the current economic strategies of fishing households. As a result, I suggest that in order to animate the sector, development policy should promote domestic fish consumption instead of general production along with investment and management of ice distribution systems. 相似文献

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. 相似文献

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. 相似文献
