TL;DR: In this article, the authors introduce new estimates of food insecurity based on food acquisition data collected directly from households as part of national household expenditure surveys (HESs) conducted in 12 Sub-Saharan African countries.
Abstract: "This report introduces new estimates of food insecurity based on food acquisition data collected directly from households as part of national household expenditure surveys (HESs) conducted in 12 Sub-Saharan African countries. The report has three objectives: (1) to explore the extent and location of food insecurity across and within the countries; (2) to investigate the scientific merit of using the food data collected in HESs to measure food insecurity; and (3) to compare food insecurity estimates generated using HES data with those reported by FAO and explore the reasons for differences between the two. The overall purpose is to investigate how the data collected in HESs can be used to improve the accuracy of FAO's estimates, which are being used to monitor the MDG hunger goal. The study is based on both diet quantity and diet quality indicators of food insecurity. The two main indicators of focus are the share of people consuming insufficient dietary energy, or the prevalence of “food energy deficiency” and the share of households with low diet diversity. The study finds these to be valid indicators of food insecurity and to be reasonably reliably measured. They are also comparable across the study countries despite differing methods of data collection." from Authors' Abstract

TL;DR: In this article, the authors estimate a new set of poverty lines that accounts for the shortcomings of the official poverty figures in Uganda by the fact that the underlying poverty lines are based on a single national food basket constructed in the early 1990s.
Abstract: Official poverty figures in Uganda are flawed by the fact that the underlying poverty lines are based on a single national food basket that was constructed in the early 1990s. In this paper, we estimate a new set of poverty lines that accounts for the wid

TL;DR: The questions for this chapter are how far climate and its change affect current food production systems and food security and the extent to which they will do so in the future.
Abstract: Many definitions of food security exist, and these have been the subject of much debate. As early as 1992, Maxwell and Smith (1992) reviewed more than 180 items discussing concepts and definitions, and more definitions have been formulated since (DEFRA, 2006). Whereas many earlier definitions centered on food production, more recent definitions highlight access to food, in keeping with the 1996 World Food Summit definition (FAO, 1996) that food security is met when “all people, at all times, have physical and economic access to sufficient, safe, and nutritious food to meet their dietary needs and food preferences for an active and healthy life.” Worldwide attention on food access was given impetus by the food “price spike” in 2007–2008, triggered by a complex set of long- and short-term factors (FAO, 2009b; von Braun and Torero, 2009). FAO concluded, “provisional estimates show that, in 2007, 75 million more people were added to the total number of undernourished relative to 2003–05” (FAO, 2008); this is arguably a low-end estimate (Headey and Fan, 2010). More than enough food is currently produced per capita to feed the global population, yet about 870 million people remained hungry in the period from 2010 to 2012 (FAO et al., 2012). The questions for this chapter are how far climate and its change affect current food production systems and food security and the extent to which they will do so in the future (Figure 7-1).

TL;DR: The unequivocal choice now is between continuing to fail as the global community did with HIV/AIDS for more than a decade or to finally make nutrition central to development so that a wide range of economic and social improvements that depend on nutrition can be realized.
Abstract: It has long been known that malnutrition undermines economic growth and perpetuates poverty. Yet the international community and most governments in developing countries have failed to tackle malnutrition over the past decades even though well-tested approaches for doing so exist. The consequences of this failure to act are now evident in the worlds inadequate progress toward the Millennium Development Goals (MDGs) and toward poverty reduction more generally. Persistent malnutrition is contributing not only to widespread failure to meet the first MDG--to halve poverty and hunger--but to meet other goals in maternal and child health HIV/AIDS education and gender equity. The unequivocal choice now is between continuing to fail as the global community did with HIV/AIDS for more than a decade or to finally make nutrition central to development so that a wide range of economic and social improvements that depend on nutrition can be realized.

TL;DR: In this paper, the authors investigated the impact of off-farm income on household food security and nutrition in Nigeria using farm survey data from Nigeria, and found that the prevalence of child stunting, underweight, and wasting is lower in households with offfarm income than in households without.

TL;DR: Evidence is provided that in Africa, crop diversification can be effective at a countrywide scale, and that shrubby, grain legumes can enhance environmental and food security.
Abstract: The Asian green revolution trebled grain yields through agrochemical intensification of monocultures. Associated environmental costs have subsequently emerged. A rapidly changing world necessitates sustainability principles be developed to reinvent these technologies and test them at scale. The need is particularly urgent in Africa, where ecosystems are degrading and crop yields have stagnated. An unprecedented opportunity to reverse this trend is unfolding in Malawi, where a 90% subsidy has ensured access to fertilization and improved maize seed, with substantive gains in productivity for millions of farmers. To test if economic and ecological sustainability could be improved, we preformed manipulative experimentation with crop diversity in a countrywide trial (n = 991) and at adaptive, local scales through a decade of participatory research (n = 146). Spatial and temporal treatments compared monoculture maize with legume-diversified maize that included annual and semiperennial (SP) growth habits in temporal and spatial combinations, including rotation, SP rotation, intercrop, and SP intercrop systems. Modest fertilizer intensification doubled grain yield compared with monoculture maize. Biodiversity improved ecosystem function further: SP rotation systems at half-fertilizer rates produced equivalent quantities of grain, on a more stable basis (yield variability reduced from 22% to 13%) compared with monoculture. Across sites, profitability and farmer preference matched: SP rotations provided twofold superior returns, whereas diversification of maize with annual legumes provided more modest returns. In this study, we provide evidence that in Africa, crop diversification can be effective at a countrywide scale, and that shrubby, grain legumes can enhance environmental and food security.
