Estimation of undernutrition, and mean calorie intake in Africa for 2005: methodology, findings and implications
Full text linkBackground: As poverty and hunger are basic yardsticks of underdevelopment and destitution, the need for reliable statistics in this domain is self-evident. While the measurement of poverty through surveys is relatively well documented in the literature, for hunger, information is much scarcer, particularly for adults, and very different methodologies are applied for children and adults. Our paper seeks to improve on this practice in two ways. One is that we estimate the prevalence of undernutrition in sub-Saharan Africa (SSA) for both children and adults based on anthropometric data available at province or district level, and secondly, we estimate the mean calorie intake and implied calorie gap for SSA, also using anthropometric data on the same geographical aggregation level. Results: Our main results are, first, that we find a much lower prevalence of hunger than presented in the Millennium Development reports (17.3% against 27.8% for the continent as a whole). Secondly, we find that there is much less spread in mean calorie intake across the continent than reported by the Food and Agricultural Organization (FAO) in the State of Food and Agriculture, 2007, the only estimate that covers the whole of Africa. While FAO estimates for calorie availability vary from a low of 1760 Kcal/capita/day for Central Africa to a high of 2825 Kcal/capita/day for Southern Africa, our estimates lay in a range of 2245 Kcal/capita/day (Eastern Africa) to 2618 Kcal/capita/day for Southern Africa. Thirdly, we validate the main data sources used (the Demographic and Health Surveys) by comparing them over time and with other available data sources for various countries. Conclusion: We conclude that the picture of Africa that emerges from anthropometric data is much less negative than that usually presented. Especially for Eastern and Central Africa, the nutritional status is less critical than commonly assumed and also mean calorie intake is higher, which implies that agricultural production and hence income must also have been growing at a pace at least high enough to keep up with population growth. In terms of methodology, our estimates form a base line for 2005 for the whole continent that can be easily updated with far less information for individual countries, as we show in an example for Ethiopia. © 2009 van Wesenbeeck et al; licensee BioMed Central Ltd

No full textDisentangling urban and rural food security in West Africa
No full textStrategies to fight hunger and early warning systems often focus on identifying food crises rather than longer-term trends, and concentrate on rural areas. Data on the food and nutrition security situation of West Africa’s growing urban population is scarce and fragmented. Using geo-referenced information available in the Demographic and Health Surveys (DHS), this report estimates the total number and prevalence of under-nutrition and over-nutrition in West Africa for both urban and rural areas. The analysis reveals that almost 110 million people in West Africa are not receiving the correct nutrition for their needs. Over 58 million people in the region are underweight, 22 million of which live in cities. Another 52 million are either overweight or obese, the large majority of whom are adult urban dwellers. This situation reveals the severity of the “double burden” of under- and over-nutrition. It also calls for greater efforts to identify appropriate metrics to monitor food and nutrition security in urban areas

No full textThe Millennium Development Goals, How Realistic Are They?
No full textIn its Millennium Declaration of September 2000, the United Nations adopted the Millennium Development Goals (MDG), to be reached in 2015 through concerted efforts worldwide. According to UN-calculations, the estimated costs in terms of additional development aid of meeting the MDGs in all countries vary from 121 billion US dollars in 2006 to 189 billion US dollars in 2015. The present communication reviews the figures reported. It appears that while Asia is well on track to achieve the goals, essentially through efforts of its own, Africa is lagging behind, albeit that according to detailed survey data on weight-for-length among adults collected in Africa for the US aid agency, rates of undernutrition are about 58 percent of the levels used as a reference by the UN, which are based on assessment of food production. Yet, child undernutrition comes out higher in these surveys. Besides mentioning reservations about the adequacy of these MDG-yardsticks, we consider the cost estimates for Africa as presented in the UN-reports and subsequently assessed in the literature. It appears that these estimates are too low, even if all MDG-funds were concentrated on this continent, essentially because they are set up as shopping lists that are necessarily incomplete and, among others, disregard many of the indirect cost of delivering the goods to the target beneficiaries, including the cost of providing adequate security and avoiding corruption. Nonetheless, recalling how hopeless the situation looked some 30 years ago for China, India, and Bangladesh, where unprecedented numbers have now escaped extreme poverty during the past decade and a half, we submit that over a time horizon of about twice the 15 years of the MDG's and with adequate international support, realization of the MDG-targets should be possible for Africa too. © Springer Science+Business Media, 2006

No full textEquilibrium selection in games: the mollifier method.
No full textThis paper introduces an embedding of a Nash equilibrium into a sequence of perturbed games, which achieves continuous differentiability of best responses by mollifying them over a continuously differentiable density with compact support (window size). Along any sequence with shrinking window size, the equilibria are single-valued whenever the function has a regular Jacobian and the set of equilibria where it is singular has measure zero. We achieve a further reduction of the equilibrium set by inserting within the embedding a procedure that eliminates the strict interior of equilibrium sets. The mollifier can be approximated consistently using kernel density regression, and we sketch a non-stationary stochastic optimization algorithm that uses this approximation and converges with probability one to an equilibrium of the original game. © 2003 Elsevier B.V.
