The State of Food Security and Nutrition in the World 2018


Book Description

New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.




Measuring resilience in a volatile world


Book Description

Substantial numbers of the world’s chronically poor and malnourished population live in an increasingly volatile world. The dangerous nexus of climate change, rapid population growth, conflict, and food price volatility already appears to have pushed several poor regions into states of permanent crisis, even as the rest of the world has seen unprecedented progress against poverty. This disturbing state of affairs, along with our expanded knowledge of the intimate interactions between short-term shocks and long-run development, has catalyzed widespread interest in resilience building, and in what such a framework implies for understanding the causes and consequences of acute vulnerability to natural and man-made disasters. In this paper we ask what this paradigm implies for the measurement and analysis of resilience. Resilience is fundamentally about complex dynamics. Slower-moving ecological, economic, demographic, and social stressors create vulnerability to short-run shocks, which in turn can have long-term consequences by reinforcing preexisting vulnerabilities. In our view, this basic conception of resilience has fundamental measurement implications. First, resilience can be measured and understood only through higher-frequency surveys that capture the causes and consequences of time-varying stressors and shocks, including seasonal shocks. Second, resilience can be understood only through surveys that capture the multidimensional complexity of stressors, shocks, and feedback loops, including the complex interactions between economic, social, and ecological forces. Third, the underlying stressors that create vulnerability, and the resilience-building interventions that reduce vulnerability, can be gauged and evaluated only over the longer term. This conceptualization of resilience motivates us to go a step further than existing research on resilience and on food and nutrition security measurement, by outlining a far more expansive strategy for improving and scaling up the monitoring, measurement, and analysis of the world’s most vulnerable populations. We propose the development of a multicountry system of high-frequency, long-term sentinel sites in the world’s most vulnerable regions. If implemented along the lines we conceive, this system could be a high-return investment for resilience-building efforts, since it would serve multiple purposes. This system offers the only rigorous means of monitoring vulnerability and resilience in the world’s most volatile regions. This system would bolster existing early-warning systems by complementing them with household-level indicators. This system would improve the targeting of emergency resources. This system would be instrumental for diagnosing the underlying sources of vulnerability, for identifying key thresholds of resilience, and for designing appropriate resilience-building strategies. And this system would provide a rigorous foundation for large-scale evaluations of resilience-building activities. While there are strong justifications for such a system, the devil is necessarily in the details, and much of this paper is concerned with those details. Largely to learn from existing experience, we first review existing measurement strategies that are similar in purpose or design to the sentinel system outlined above. When implemented, long-term, high-frequency measurement systems have often yielded great benefits but been hampered by cost, lack of institutional coordination, and insufficient dissemination and usage of data. The need to keep costs down and benefits widespread therefore motivates us to consider which countries in the world have the highest priority for the development of sentinel sites, based on indicators such as child nutrition and health outcomes, exposure to disasters, and past emergency assistance levels from the international community. We then turn to crucial issues of data collection design by outlining a hybrid sampling and survey design that will help achieve the various objectives outlined above while keeping costs down. We also argue that the proliferation of mobile phones and other information and communications technologies offers substantial scope for a cost-effective system of this kind, far more so than would have been available in the past. Finally, we consider who should lead and contribute to this ambitious effort. Since the principal advantage of this approach is that it can yield benefits for a wide range of institutions and purposes (relief and development, operations and research, social and biophysical sciences), and since the costs of a long-term commitment to these sentinel surveys would be large indeed for any single agency, we propose the need for a relatively broad consortium of international donors. This consortium should first focus on establishing partnerships with national governments and then commit to long-term resilience monitoring as well as domestic capacity building. With this essential commitment in place, this consortium would then need to secure implementing partners with a permanent presence on the ground, as well as the technical expertise of international organizations of various sorts. Ultimately, we argue, it is only this kind of long-term, cooperative commitment that will provide a scientific evidence base for diagnosing and resolving the world’s worst problems of hunger, poverty, and malnutrition. Only this kind of sentinel system can generate the data and evidence needed to inform actions to build resilience and to help the global community eliminate extreme poverty in the generation ahead. The status quo is simply not enough.







Measures and Determinants of Urban Food Security: Evidence from Accra, Ghana


Book Description

The urban population in Africa south of the Sahara (SSA) is expected to expand rapidly from 376 million people in 2015 to more than 1.25 billion people by 2050. Measuring and ensuring food security among urban households will become an increasingly pertinent task for development researchers and practitioners. In this paper we characterize food security among a sample of low- and middle-income residents of Accra, Ghana, using 2017 survey data. We find that households tend to purchase food from traditional markets, local stalls and kiosks, and street hawkers, and rarely from modern supermarkets. We characterize food security using three established metrics: the Household Food Insecurity Access Scale (HFIAS); the Household Food Insecurity Access Prevalence (HFIAP); and the Food Consumption Score (FCS). We then estimate the determinants of food security using general linear models. The food security metrics are not strongly correlated. For example, according to HFIAP, as many as 70 percent of households sampled are food insecure, but only 2 percent fall below acceptable thresholds measured by FCS. Model results show that household education, assets, and dwelling characteristics are significantly associated with food security according to HFIAS and HFIAP, but not with FCS. The poor correlation and weak model agreement between the dietary recall metric, FCS, and the experience-based metrics, HFIAS and HFIAP, call for closer attention to measurement of urban food security. Given Africa’s urban future, our findings highlight the need for an urban-oriented comprehensive approach to the food security of urban households.




Nutrition and Fitness


Book Description

Mens sana in corpore sano (a healthy mind in a healthy body) is a Latin phrase taken from Giovenale (Satire, X, 356) that remains relevant and is supported by today’s data regarding genetics and nutrition, and their contribution to mental health. The purpose of this Special Issue on “Nutrition and Fitness: Mental Health” is to provide an update on the latest evidence regarding the association between nutrition, physical activity (and inactivity) and physical fitness, and the mental health of children, adolescents, and adults. Particularly, papers (reviews and clinical or experimental studies) dealing with the association between nutrition, physical fitness, and mental health both in general and with regard to specific mental disorders, and nutrients and physical activity as agents for prevention, treatment, or augmentation of treatment for mental disorders, will be included.




A Sustainability Challenge


Book Description

The National Research Council's Science and Technology for Sustainability Program hosted two workshops in 2011 addressing the sustainability challenges associated with food security for all. The first workshop, Measuring Food Insecurity and Assessing the Sustainability of Global Food Systems, explored the availability and quality of commonly used indicators for food security and malnutrition; poverty; and natural resources and agricultural productivity. It was organized around the three broad dimensions of sustainable food security: (1) availability, (2) access, and (3) utilization. The workshop reviewed the existing data to encourage action and identify knowledge gaps. The second workshop, Exploring Sustainable Solutions for Increasing Global Food Supplies, focused specifically on assuring the availability of adequate food supplies. How can food production be increased to meet the needs of a population expected to reach over 9 billion by 2050? Workshop objectives included identifying the major challenges and opportunities associated with achieving sustainable food security and identifying needed policy, science, and governance interventions. Workshop participants discussed long term natural resource constraints, specifically water, land and forests, soils, biodiversity and fisheries. They also examined the role of knowledge, technology, modern production practices, and infrastructure in supporting expanded agricultural production and the significant risks to future productivity posed by climate change. This is a report of two workshops.




The impact of cash and food transfers: Evidence from a randomized intervention in Niger


Book Description

There is little rigorous evidence on the comparative impacts of cash and food transfers on food security and food-related outcomes. We assess the relative impacts of receiving cash versus food transfers using a randomized design. Drawing on data collected in eastern Niger, we find that households randomized to receive a food basket experienced larger, positive impacts on measures of food consumption and diet quality than those receiving the cash transfer.




The Feeding of Nations


Book Description

In the last decade, the world has grown richer and produced more food than ever before. Yet in that same period, hunger has increased and 925 million remain underfed and malnourished. Exploring this troubling paradox, The Feeding of Nations: Re-Defining Food Security for the 21st Century offers a glimpse into how the simple aspiration of global food security has evolved and unfolded—with sometimes contradictory and counterproductive policies, agendas, and ideologies. Providing a holistic analysis of the issues surrounding food security, this volume engages in a cross-disciplinary approach that makes the subject accessible to readers and academically rigorous in delivery. Topics discussed include: A brief overview of our current understanding of the prevalence of hunger and malnutrition Historical perspectives on the feeding of nations, to understand how we arrived at this point Contemporary motivations that led to the creation of the modern concept of food security The many different sectors related to food security, including agriculture, environment, and policy The goals that society has set regarding food security, the means by which these are to be achieved, and current thoughts on solutions The book contains a broad set of appendices that enable focused study on critical topics presented in the text. Uniquely amalgamating all the disparate elements of food security into one volume, it sets the record straight about the origins and evolution of the phenomenon while dispelling myths along the way.




Food Insecurity and Public Health


Book Description

Affecting more than 800 million people, food insecurity is a global problem that runs deeper than hunger and undernutrition. In addition to the obvious impact on physical well-being, food insecurity can result in risky coping strategies, increased expenditures on medical costs or transportation, and mental health issues. A review of the concepts an




Filets Sociaux (Jigisémèjiri) program midline report


Book Description

This report presents findings from the impact evaluation of the Jigisémèjiri program at midline. It first provides background on the evaluation, including details on the program and interventions. It then relates first-order, second-order, and third-order outcomes of interest in a conceptual framework, which guides our analysis and structures the report. The report next describes the evaluation design, sampling, and data collection process. It then presents statistics on beneficiaries’ experience with the CTs and AM. Last, it uses the baseline and midline data, exploiting the randomized design, to estimate the impacts of the program on its beneficiary population at midline, distinguishing between household-level outcomes and child-level outcomes. Given that the baseline report showed that the randomization process was successful at creating similar groups for comparison for the impact evaluation with similar preprogram characteristics, the impacts at midline can be interpreted as truly caused by the program rather than simply correlated with its receipt.
