Are Malawian Diets Changing? An assessment of nutrient consumption and dietary patterns using household-level evidence from 2010/11 and 2016/17


Book Description

This paper provides an updated analysis of the dietary patterns of Malawian households and their consumption of select nutrients - calories, protein, iron, vitamin A, zinc, and folate - using data from the third (2010/11) and fourth (2016/17) rounds of the Malawi Integrated Household Survey (IHS). Changes in food and nutrient consumption patterns between the two survey periods are examined across household wealth categories and across regions. Dietary diversity and patterns of food and nutrient consumption are found to differ significantly between rural and urban areas. Whereas urban households largely saw slightly increased or stable nutrient consumption between 2010/11 and 2016/17, most households in rural areas saw declines over this period. We also document small shifts in the relative amounts of foods consumed over this six-year period in both rural and urban households, with increased consumption of fish and pulses, legumes, and nuts, and decreases in meat, fruit, dairy, and root and tuber consumption. The contribution of animal-source foods as a share of total protein consumption remains low at between 10 and 20 percent, depending on the region, with the overall share of protein from animal-source foods falling slightly between the two surveys. With regards to adequacy of household diets for meeting nutrient requirements, in the absence of nutrient supplementation, many individuals will be subject to iron, vitamin A, and folate inadequacies. Of particular concern, the poorest households have very low nutrient consumption per person and have diets that rely on only a few foods from a small number of food groups. For all six nutrients, nationally just over half of the total amount of nutrient consumed came from food that was purchased. While we would expect this for urban households, even for rural households more than half of all calories and protein consumed came from foods that were purchased. For micronutrients consumed by rural households, between 40 and 50 percent came from purchased foods. While in the past, own production of food may have provided most Malawian households with most of the nutrients they consumed, this is no longer the case. For most Malawian households, including in rural communities, their food security and dietary nutritional needs now are equally tied to the market as to their own farming, if not more so. Drawing lessons from the analysis here for improving the food consumption data collected in the IHS surveys, more detailed and further disaggregated data would be beneficial, particularly to help estimate nutrients derived from fortified and processed foods. Additional information on how food is shared within households would also allow for a better understanding of nutrient inadequacies at the individual level. Collecting more information on the content of the meals that household members eat away from home would also be helpful in removing some uncertainty in the nutrient consumption estimates made from the data. Finally, additional information on food gifts received could clarify aspects of household coping strategies, the performance of formal social safety nets, and food choice.







Changes in food and nutrition security in Malawi


Book Description

A large proportion of Malawian households are caught in a trap where poverty and food insecurity reinforce one another and where periods of food deficits and severe food crises are frequent occurrences. In recognition of this, the Malawian government has since 2005/06 implemented a large-scale Farm Input Subsidy Program (FISP), which supplies half of smallholder farmers with sufficient fertilizer and maize seeds to satisfy the maize consumption needs of an average-sized family. While the program boosted maize production and lowered maize prices, thus ensuring increased caloric availability at the household level, its effect on overall food consumption, dietary diversity, micronutrient deficiency, and child nutrition is less clear. This study evaluates household expenditure survey data to measure changes in nutrition outcomes between 2004/05 and 2010/11.




Mapping the linkages between agriculture, food security and nutrition in Malawi


Book Description

Smallholder agriculture is the mainstay of Malawi’s economy. Its importance for livelihoods cannot be overstated. 94 percent of rural residents and 38 percent of urban residents engage in agriculture to some extent (Jones, Shrinivas, and Bezner-Kerr 2014), the vast majority as smallholder farmers with landholdings of less than one hectare. Smallholder crops are primarily maize—which accounted for nearly 80 percent of smallholder-cultivated land in 2011 —followed by cassava and other food crops (FAO 2008; IFAD 2011). These foods are grown for household consumption and for sale at local and regional markets. As such, the Malawian food supply, especially in rural areas where markets are thin with few buying or selling options, is shaped largely by trends in smallholder food-crop production




Agriculture, food security, and nutrition in Malawi: Leveraging the links


Book Description

Although the Malawian food supply is shaped largely by trends in smallholder food crop production, Ma­lawi’s decades-long focus on improving smallholder productivity has only moderately improved food secu­rity and nutrition outcomes. Country statistics indicate an estimated 36.7 percent of rural Malawian house­holds failed to access sufficient calories between 2010 and 2011. During the same period, 47 percent of children under the age of five years were esti­mated to be stunted in their growth. These indicators imply that some Malawian diets are lacking in terms of quantity (total calories consumed), and most are lacking in terms of quality (sufficient calories derived from nutrient-dense foods, such as meat, fish, eggs, dairy, legumes, fruits, and vegetables). Good nutrition requires both enough total calories (quantity) and enough vitamins and minerals per calorie (quality). How can Malawi better leverage its smallholder agriculture sector to improve nutrition? This report provides a series of primary and secondary data anal­yses that examine different aspects of this question.

A History of Water: Series III, Volume 3


Book Description

Major changes in policy and management , across the entire agricultural production chain, will be needed to ensure the best use of available water resources in meeting growing demands for food and other agricultural products. This new volume in the successful History of Water Series focuses on the African continent to address this key issue. Humanity has its roots in Africa and many of our food systems developed there. All types of agricultural production are present and the sheer size of the continent offers wide ecological variation from extreme desert to dense rainforest. Drawing together leading international contributors from a wide variety of disciplines Water and Food offers new insights into the evolution of food systems, from early hunter gatherers to the global challenges of the modern world.




Universal Food Security


Book Description

What would it take to achieve a genuinely food-secure world—one without hunger or malnutrition, where everyone gets to consume the right quantity and quality of food to live a healthy, active, and productive life? Bringing about such a future requires transforming how our food is grown, managed, and distributed. From production to consumption, food systems must be sustainable, halting environmental degradation and even repairing the damage we have previously done. This book provides an accessible guide to making healthy diets from sustainable food systems available to all. Glenn Denning bridges the divisive worlds of science, policy, and practice. He synthesizes the most relevant literature and shares personal perspectives and insights gained over four decades working in more than fifty countries, coupled with the real-world experience of hundreds of leading experts. Universal Food Security lays out key priorities—sustainable intensification, market infrastructure, postharvest stewardship, healthy diets, and social protection—and presents how to achieve food systems transformation. Denning identifies the education and development of practitioner-leaders as the critical trigger of change. Universal Food Security informs and inspires those leaders—acting on their own and with others through institutions—to achieve a food-secure world. This book is an ideal handbook for students and practitioners looking to transform our food systems at all levels.




Malawi


Book Description

Malawi is one of the poorest countries on the globe. Subsistence agriculture remains at the very heart of its social fabric, and also lies at the root of its tremendous poverty. Yet while Malawi is among the worst performers in terms of per capita income and infant mortality, it is also a surprising leader in other areas (such as freedom of the press), has enjoyed over fifty years of relative stability since independence, and still holds great potential for economic development. Bringing together some of the leading experts on the country, this collection offers a comprehensive introduction to contemporary Malawi, encompassing its economy, culture, and politics. An invaluable resource for scholars and development professionals alike, the book assesses the root causes of Malawi's impoverishment, and also offers insight into how the country might break out of its development impasse.




Bugs as Drugs


Book Description

Examining the enormous potential of microbiome manipulation to improve health Associations between the composition of the intestinal microbiome and many human diseases, including inflammatory bowel disease, cardiovascular disease, metabolic disorders, and cancer, have been elegantly described in the past decade. Now, whole-genome sequencing, bioinformatics, and precision gene-editing techniques are being combined with centuries-old therapies, such as fecal microbiota transplantation, to translate current research into new diagnostics and therapeutics to treat complex diseases. Bugs as Drugs provides a much-needed overview of microbes in therapies and will serve as an excellent resource for scientists and clinicians as they carry out research and clinical studies on investigating the roles the microbiota plays in health and disease. In Bugs as Drugs, editors Robert A. Britton and Patrice D. Cani have assembled a fascinating collection of reviews that chart the history, current efforts, and future prospects of using microorganisms to fight disease and improve health. Sections cover traditional uses of probiotics, next-generation microbial therapeutics, controlling infectious diseases, and indirect strategies for manipulating the host microbiome. Topics presented include: How well-established probiotics support and improve host health by improving the composition of the intestinal microbiota of the host and by modulating the host immune response. The use of gene editing and recombinant DNA techniques to create tailored probiotics and to characterize next-generation beneficial microbes. For example, engineering that improves the anti-inflammatory profile of probiotics can reduce the number of colonic polyps formed, and lactobacilli can be transformed into targeted delivery systems carrying therapeutic proteins or bioengineered bacteriophage. The association of specific microbiota composition with colorectal cancer, liver diseases, osteoporosis, and inflammatory bowel disease. The gut microbiota has been proposed to serve as an organ involved in regulation of inflammation, immune function, and energy homeostasis. Fecal microbiota transplantation as a promising treatment for numerous diseases beyond C. difficile infection. Practical considerations for using fecal microbiota transplantation are provided, while it is acknowledged that more high-quality evidence is needed to ascertain the importance of strain specificity in positive treatment outcomes. Because systems biology approaches and synthetic engineering of microbes are now high-throughput and cost-effective, a much wider range of therapeutic possibilities can be explored and vetted.
