This study examines the effect of agricultural productivity change on child nutritional outcomes in Nigeria. Using several waves of micro-level panel data from Nigeria, we first show that high temperature (heat stress) reduces agricultural productivity change. A one percent increase in high temperatures during the crop growth period result in a 4 percent decrease in agricultural productivity. More importantly, our analysis provides several important insights on the implications of agricultural productivity change for reducing child undernutrition. The results show that agricultural productivity growth has a positive effect on child nutritional outcomes, measured by child height-for-age and weight-for-age. The main channel through which agricultural productivity growth affects child nutritional outcomes is by increasing food production for own household consumption. This suggests that productivity-enhancing investments in the agricultural sector could have a direct impact on child nutritional outcomes among smallholder households in Nigeria. The results also show that agricultural productivity change has higher impact for households who have better access to markets and a higher educational level. Interventions and policies geared towards intensification of agricultural production need to be complemented with strategies for widening educational programs and improving farmers’ access to markets. to induce incentives for increased production.

Current data and trends in morbidity and mortality for the sub-Saharan Region as presented in this new edition reflect the heavy toll that HIV/AIDS has had on health indicators, leading to either a stalling or reversal of the gains made, not just for communicable disorders, but for cancers, as well as mental and neurological disorders.

A growing number of governments, donor agencies, and development organizations are committed to supporting nutrition-sensitive agriculture (NSA) to achieve their development goals. Although consensus exists on pathways through which agriculture may influence nutrition-related outcomes, empirical evidence on agriculture’s contribution to nutrition and how it can be enhanced is still weak. This paper reviews recent empirical evidence (since 2014), including findings from impact evaluations of a variety of NSA programs using experimental designs as well as observational studies that document linkages between agriculture, women’s empowerment, and nutrition. It summarizes existing knowledge regarding not only impacts but also pathways, mechanisms, and contextual factors that affect where and how agriculture may improve nutrition outcomes. The paper concludes with reflections on implications for agricultural programs, policies, and investments, and highlights future research priorities.

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.

Malnutrition -- in the form of undernutrition, micronutrient deficiencies, and overweight and obesity -- imposes unacceptably high economic and social costs on countries at all income levels. The causes of malnutrition are complex, yet all forms of malnutrition share one common feature: nutritionally inappropriate diets. The State of Food and Agriculture 2013 makes the case that healthy diets and good nutrition begin with food and agriculture.

Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.

This monograph, A World without Agriculture, was the 2007 Henry Wendt Lecture, delivered at the American Enterprise Institute (AEI) in Washington, D.C. on October 30, 2007. The Wendt Lecture is delivered annually by a scholar who has made major contributions to our understanding of the modern phenomenon of globalization and its consequences for social welfare, government policy, and the expansion of liberal political institutions.

Agricultural development has long been considered an important driver of overall economic development in developing countries such as Nigeria. Whether increasing public expenditures on agriculture (PEA) can directly improve broad dimensions of household well-being has continued to be debated. In addition, there has been growing interest in the economic flexibility of households to switch between nonfarm and farming activities. Such flexibility can potentially enhance the resilience of households to shocks like the COVID-19 pandemic in today’s rapidly changing socioeconomic environments. Direct evidence of the impact of PEA on broad development outcomes is also important in informing regional initiatives aiming to use PEA as an instrument for overall food security enhancement and poverty reduction in Africa. Using state- and local government area (LGA)-level PEA figures and household data in Nigeria, this study aims to provide initial evidence at the household level in Nigeria. The findings suggest that greater PEA shares have positive effects on various development outcomes at the household level, including consumption, poverty reduction, nonfarm capital investments, and household dietary diversity. The findings also suggest that greater PEA shares are likely to help farm households enhance their economic flexibility. These findings are consistent with the hypotheses of positive linkages between PEA and agricultural outcomes, and linkages between agricultural and nonagricultural outcomes, often advocated in the literature. PEA should be increased by increasing its share of total public expenditures through conscious efforts to reallocate existing resources, rather than trying to increase it by increasing the overall size of public expenditures. Furthermore, it remains important to identify the appropriate sources (for example, spending by LGA or state) and types of PEA (for example, recurrent or capital spending) for particular development outcomes.

One in three preschool children in developing countries is undernourished. Consequently, they are likely to have impaired immune systems, poor cognitive development, low productivity as adults, and susceptibility to diet-related chronic diseases such as hypertension and coronary heart disease later in life. Undernourished female preschoolers are likely to grow into undernourished young women who are more likely to give birth to babies who are undernourished even before they are born, thus perpetuating the intergenerational transmission of deprivation. This report sheds light on some of the main causes of child malnutrition, projects how many children are likely to be malnourished in the year 2020 given current trends, and identifies priority actions for reducing malnutrition most quickly in the coming decades.
