Improving bean production and consumption in Zimbabwe baseline report

This report presents descriptive information from a baseline study conducted in 2016 to benchmark the indicators of outcomes of the flagship initiative in Zimbabwe, understand the drivers of bean improved technology adoption and potential impacts of the initiative. The primary data from 752 bean growing households that were selected from 15 districts with highest bean area were used. These districts were selected from a list of 60 districts because they allocate the largest area to bean production in 2013-2015. Study findings revealed increased severity of bean production constraints that significantly reduce bean productivity, thus PABRA focus on Zimbabwe as a flagship country for improving bean production and productivity will help poorer households access more bean for consumption. So far, households demonstrate limited awareness of improved technologies including varieties, which calls for enhanced dissemination in terms of geographical scope and capacity of farmers on how to implement it profitably. Interventions should also account for the risk of rainfall failure by putting emphasis on climate smart technologies. Irrigation is one of climate smart technologies that have been promoted in Zimbabwe and is helping farmers make huge profits from bean production. These farms have a potential to produce more surplus for marketing after expanding their area under beans. Simulations under various scenarios revealed that for the new technology to be attractive to farmers, they should generate at least yield increase of 30%. Technologies will be attractive even with 10% yield increase if adoption is accompanied by irrigation. However, use of irrigation is associated with increased demand for hired and family labour, with women likely to bear more burden of extra unpaid labour. All interventions need to be sensitive to gender as women and men contribute unpaid labour and participate in decision making for bean production and marketing but with varying intensities in specific activities or decisions

Assessing the impact of a food supplement on the nutritional status and body composition of HIV-infected Zambian women on ARVs

Background Zambia is a sub-Saharan country with one of the highest prevalence rates of HIV, currently estimated at 14%. Poor nutritional status due to both protein-energy and micronutrient malnutrition has worsened this situation. In an attempt to address this combined problem, the government has instigated a number of strategies, including the provision of antiretroviral (ARV) treatment coupled with the promotion of good nutrition. High-energy protein supplement (HEPS) is particularly promoted; however, the impact of this food supplement on the nutritional status of people living with HIV/AIDS (PLHA) beyond weight gain has not been assessed. Techniques for the assessment of nutritional status utilising objective measures of body composition are not commonly available in Zambia. The aim of this study is therefore to assess the impact of a food supplement on nutritional status using a comprehensive anthropometric protocol including measures of skinfold thickness and circumferences, plus the criterion deuterium dilution technique to assess total body water (TBW) and derive fat-free mass (FFM) and fat mass (FM). Methods/Design This community-based controlled and longitudinal study aims to recruit 200 HIV-infected females commencing ARV treatment at two clinics in Lusaka, Zambia. Data will be collected at four time points: baseline, 4-month, 8-month and 12-month follow-up visits. Outcome measures to be assessed include body height and weight, body mass index (BMI), body composition, CD4, viral load and micronutrient status. Discussion This protocol describes a study that will provide a longitudinal assessment of the impact of a food supplement on the nutritional status of HIV-infected females initiating ARVs using a range of anthropometric and body composition assessment techniques

Quality characteristics and acceptability of low cost weaning blends by Zambian mothers

Stunting, and to a lesser extent wasting and undernutrition, of children under five years constitutes a serious health problem in Zambia. Although non-nutritional causes such as infection and poverty importantly exacerbate these conditions, improvements in the diets of children is vital for better health. The age interval beginning at about six months is an especially vulnerable time for children, when they are being weaned from breast milk to conventionally used cultural foods. The current study reports assessments by mothers of nine experimental weaning mixtures, formulated by computer to be low cost and nutritionally superior to maize meal alone. An incomplete block design with randomization was used to compare the nine weaning food blends, differentially constituted to address specific conditions. One group of 127 mothers (or guardians) of children 6 to 27 months judged cooked porridges prepared from the blends. The alternate group of 140 mothers of children from 5 to 30 months evaluated characteristics of uncooked porridge ingredients. Statistical analyses of hedonic scale ratings and tabulation of mothers’ voluntary comments were performed. With few exceptions, blend macronutrient/energy characteristics generally conformed to proposed standards in Codex Alimentarius and other literature guidelines. Mixture levels of 20 vitamins and minerals were estimated. A rice-containing formula was most expensive and a high maize/moderate soy formulation the least costly in price assessment. Acceptability results showed that in addition to maize meal and nonfat dry milk, the most acceptable mixtures contained bambara nuts or soybeans as chief ingredients. Blends with substantial percentages of millet, sorghum, or kapenta were not ordinarily acceptable. It was observed that all four cooked porridge quality factors were significantly (p ≤ 0.01) related with each other, and that both ingredient set rating categories were likewise significantly (p ≤ 0,01) related. It is emphasized that nutrient contributions of the weaning mixtures are meant for further complementation by concurrent feeding of breast milk, by appropriate use of micronutrient powders or lipidbased micronutrient spreads, and by market or home produced foods. Acceptability results of this study may be influenced by factors such as commodity cost variations, food donations, mother education, and processing cooperatives

Common Bean variety releases in Africa

The Pan Africa Bean Research Alliance is a network of national agricultural research centers (NARS), and private and public sector institutions that work to deliver better beans with consumer and market preferred traits to farmers. The datasets presented here draw from 17 Sub Saharan countries that are members of PABRA. The dataset on released bean varieties is a collection of 357 bean varieties released by NARS and there characteristics. The dataset on bean varieties and the relationship to constraints provides the 357 bean varieties on the basis of resistance to constraints such as fungal, bacterial, viral, diseases and tolerance to abiotic stresses. There is also a dataset of bean varieties that have been released in more than one country, useful for moving seed from one country to another and facilitating regional trade. The dataset on Niche market traits provides the market defined classifications for bean trade in Sub Saharan Africa as well as varieties that fall into these classifications. The datasets are an update to the 2011 discussion on PABRAs achievement in breeding and delivery of bean varieties in Buruchara et. 2011 in pages 236 and 237 here: http://www.ajol.info/index.php/acsj/article/view/74168 . It is also an update to a follow up to this discussion in Muthoni, R. A., Andrade, R. 2015 on the performance of bean improvement programmes in sub-Saharan Africa from the perspectives of varietal output and adoption in chapter 8. here: http://dx.doi.org/10.1079/9781780644011.0148.
