    Anomaly or Augury? Global Food Prices Since 2007

    Get PDF
    This article reviews the dynamics of global food prices since the food crisis of2007–08, the extent to which international prices have influenced national prices and poverty and wellbeing outcomes, and considers whether this exceptional period represents an anomaly or likely signals future episodes of food price volatility. It finds that although some factors that contributed to recent events have eased considerably, some significant drivers remain structural threats to future food security. There is little reason to be confident that recent reductions in food prices and volatilities augur well for the food security or wellbeing of those living on low and precarious incomes in the future

    Efficiency, food security and differentiation in small-scale irrigation agriculture: Evidence from North West Nigeria

    Get PDF
    Ambiguity over the effectiveness of agricultural intervention is more pronounced in rural areas where the majority of North West Nigeria’s poor population, and those involved in agriculture, reside. Further characterising these areas is the paucity of research on the issue of differentiation within the smallholder community. Specifically, definite classification of households based on efficiency, food security and income status remains inadequate. The study explores smallholder households’ differentials on the basis of these three phenomena, and other factors that affect smallholder typologies. Data was collected from 306 randomly selected smallholders involved in the Middle Rima Valley Irrigation Project, Sokoto State, Nigeria. Smallholders’ technical efficiency and households’ Food Consumption Score (FCS) were assessed. Also, Pearson correlation analysis, a segmentation approach using cluster analysis and multinomial regression model were used for the study. The study showed that the mean efficiency level of smallholder farms was 85.9% and that the majority of the households were food insecure

    Transdisciplinary Project Communication and Knowledge Sharing Experiences in Tanzania and Zambia through a One Health Lens

    The project “Strengthening food and nutrition security through family poultry and crop integration in Tanzania and Zambia” brings together animal, crop, and human health specialists, economists, ecologists, social scientists, and practitioners to work with participating communities. It aims to increase poultry value chain, crop farming systems efficiency, and household food and nutrition security and thus requires understanding of, and ability to work effectively within, complex systems. In this context, communication knowledge sharing and synthesis between stakeholders from diverse backgrounds and a range of experiences, perspectives, agendas, and knowledge is a challenge. To address this situation, communication is conceived as a dialog and a participatory process bringing together all stakeholders. This process results in unanticipated and unexpected results that require a high degree of flexibility and adaptability from team members. The paper analyses the approach and aim of the communication strategy developed for the project and the challenges faced

    Consumer acceptance of quality protein maize (QPM) in East Africa

    BACKGROUND : Undernutrition in sub-Saharan Africa remains problematic, and quality protein maize (QPM) can benefit populations whose diets are heavily based on maize and who are consequently at risk for inadequate intakes of quality protein. However, the changes in QPM‟s chemical composition may affect its sensory characteristics and, hence, acceptance. Acceptance tests were, therefore, conducted to evaluate QPM varieties in three East African countries using central location tests with one or two varieties in each country, using the most popular preparations: ugali (Tanzania), githeri (Kenya), and injera (Ethiopia). In total, 281 urban and rural consumers of both sexes and varying levels of education evaluated the products on standard sensory criteria: appearance, aroma, texture, taste, and overall, using a Likert scale.RESULTS : The results show African consumers can differentiate QPM products from their conventional counterparts, indicating that the QPM trait results in distinguishable sensory changes. Analysis by ordinal mixed regression models showed that consumers found QPM acceptable and even preferable to conventional maize. CONCLUSION : The sensory characteristics of QPM are, therefore, no impediment to its adoption; on the contrary, when coupled with good agronomic performance, they may help its utilization, leading to a positive impact in nutritionally vulnerable populations.Canadian International Development Agency (CIDA) and the Nutritious Maize for Ethiopia (NuME) Projecthttp://onlinelibrary.wiley.com/journal/10.1002/(ISSN)1097-00102015-05-30hb201

    How effective are on-farm conservation land management strategies for preserving ecosystem services in developing countries? A systematic map protocol

    Get PDF
    Background An extensive body of literature in the field of agro-ecology claims to show the positive effects that maintenance of ecosystem services can have on sustainably meeting future food demand, by making farms more productive and resilient, and contributing to better nutrition and livelihoods of farmers. In Africa alone, some research has estimated a two-fold yield increase if food producers capitalize on new and existing knowledge from science and technology. Site-specific strategies adopted with the aim of improving ecosystem services may incorporate principles of multifunctional agriculture, sustainable intensification and conservation agriculture. However, a coherent synthesis and review of the evidence of these claims is largely absent, and the quality of much of this literature is questionable. Moreover, inconsistent effects have commonly been reported, while empirical evidence to support assumed improvements is largely lacking. Objectives This systematic map is stimulated by an interest to (1) collate evidence on the effectiveness of on-farm conservation land management for preserving and enhancing ecosystem services in agricultural landscapes, by drawing together the currently fragmented and multidisciplinary literature base, and (2) geographically map what indicators have been used to assess on-farm conservation land management. For both questions, we will focus on 74 low-income and developing countries, where much of the world’s agricultural expansion is occurring, yet 80% of arable land is already used and croplands are yielding well below their potential. Methods/Design To this end, reviewers will systematically search bibliographic databases for peer-reviewed research from Web of Science, SCOPUS, AGRICOLA, AGRIS databases and CAB abstracts, and grey literature from Google Scholar, and 22 subject-specific or institutional websites. Boolean search operators will be used to create search strings where applicable. Ecosystem services included in the study are pollination services; pest-, carbon-, soil-, and water-regulation; nutrient cycling; medicinal and aromatic plants; fuel wood and cultural services. Outputs of the systematic map will include a database, technical report and an online interactive map, searchable by topic. The results of this map are expected to provide clarity about synergistic outcomes of conservation land management, which will help support local decision-making

    Emerging Avenues for Utilization of Exotic Germplasm

    Get PDF
    Breeders have been successful in increasing crop performance by exploiting genetic diversity over time. However, the reported annual yield increases are not sufficient in view of rapid human population growth and global environmental changes. Exotic germplasm possesses high levels of genetic diversity for valuable traits. However, only a small fraction of naturally occurring genetic diversity is utilized. Moreover, the yield gap between elite and exotic germplasm widens, which increases the effort needed to use exotic germplasm and to identify beneficial alleles and for their introgression. The advent of high-throughput genotyping and phenotyping technologies together with emerging biotechnologies provide new opportunities to explore exotic genetic variation. This review will summarize potential challenges for utilization of exotic germplasm and provide solutions

    The Double Burden of Malnutrition: A Systematic Review of Operational Definitions

    Get PDF
    Background Despite increasing research on the double burden of malnutrition (DBM; i.e., coexisting over- and undernutrition), there is no global consensus on DBM definitions. Objectives To identify published operational DBM definitions, measure their frequency of use, and discuss implications for future assessment. Methods Following a structured search of peer-reviewed articles with terms describing “overnutrition” [e.g., overweight/obesity (OW/OB)] and “undernutrition” (e.g., stunting, micronutrient deficiency), we screened 1920 abstracts, reviewed 500 full texts, and extracted 623 operational definitions from 239 eligible articles. Results We organized three identified DBM dimensions (level of assessment, target population, and forms of malnutrition) into a framework for building operational DBM definitions. Frequently occurring definitions included coexisting: 1) OW/OB and thinness, wasting, or underweight (n = 289 occurrences); 2) OW/OB and stunting (n = 161); 3) OW/OB and anemia (n = 74); and 4) OW/OB and micronutrient deficiency (n = 73). Conclusions Existing DBM definitions vary widely. Putting structure to possible definitions may facilitate selection of fit-for-purpose indicators to meet public health priorities
