Women’s empowerment boosts the gains in dietary diversity from agricultural technology adoption in rural Kenya

Using new survey data from rural Kenya, this paper assesses the moderating effect of women’s empowerment on the relationship between agricultural technology adoption and women’s dietary diversity. We use a multiple treatment endogenous switching regression framework to control for potential endogeneity of women’s empowerment and technology adoption. We find that women’s empowerment has a positive and significant effect on the women’s dietary diversity score regardless of technology adoption status. We further show that women’s empowerment enhances the positive effects of technology adoption on women’s dietary diversity. Although technology adoption has a positive impact on women’s dietary diversity regardless of empowerment status, its effect is stronger for households with empowered vs. disempowered women. Study results suggest that individual and household welfare could be enhanced to a greater degree through interventions that promote women’s empowerment and technology adoption simultaneously rather than separately

Patterns of knowledge and condom use among population groups: results from the 2005 Ethiopian behavioral surveillance surveys on HIV

<p>Abstract</p> <p>Background</p> <p>Behavioral surveys help interpret the magnitude of HIV/AIDS. We analyzed indicators of knowledge on HIV/AIDS and condom use among sub populations selected for behavioral surveillance in Ethiopia.</p> <p>Methods</p> <p>We used 2005 HIV/AIDS behavioral data from ten target groups. These were female sex workers, defense forces, police force, pastoralists, truck drivers, intercity bus drivers, road construction workers, teachers, factory workers and people in ANC catchment areas.</p> <p>Results</p> <p>Data from 14,524 individuals were analyzed. The majority were males (63.6%). Overall, knowledge of the three preventive methods, misconceptions and comprehensive knowledge was 57%, 75% and 18.5%, respectively. Female sex workers and the defense force showed some behavioral change in using a condom during the most recent sexual encounter and consistently used a condom with non-regular sexual partners and paying partners. Women, pastoralists and the illiterate were less likely to use condom.</p> <p>Conclusion</p> <p>Misconceptions about the transmission of HIV were high and comprehensive knowledge about HIV & AIDS was low, particularly among pastoralists. Consistent condom use and condom use during the last sexual encounter were high among both female sex workers and defense force employees, both with paying and non-regular sexual partners. This might be a positive sign, though a considerable proportion in each target group did not report using a condom during sex with non-regular partners.</p

The status of hygiene and sanitation practice among rural model families of the Health Extension Program (HEP) in Wolayta and Kembata Tembaro Zones of Southern Nations, Nationalities and Peoples’ Region of Ethiopia

Background: Since the Health Extension Program (HEP) started the training and graduation of model families, little is known about the status and maintenance of hygiene and sanitation practice to inform future directions and decisions.Objective: to assess the status and maintenance of hygiene and sanitation practices among rural model families of the Health Extension Program.Method: A cross-sectional comparative study was conducted from Dec.-June 2010/11 in Wolayta and Kembata Tembaro Zones of Southern Nations, Nationalities and Peoples Regional State of Ethiopia. Two types of comparisons were involved in the study; comparison of hygiene and sanitation practices of a randomly selected 690 model families and 686 non-model families, and comparison of similar practices among model families at the time of graduation, assessed in retrospective interview, versus at the time of survey. Quantitative data were collected from the two zones from Dec- Jan. 2010/11. Qualitative data were also collected in June 2011 to complement the findings of the quantitative data from a purposively selected group of women and men among model families in the study areas. Descriptive and analytics statistics were used to analyse the quantitative data using STATA version 10 while the qualitative data were analysed using Open Code version 3.6.2.0Results: The study showed that among model families, 82% of them had pit latrine, 23.1 % had solid and liquid waste disposal pits, 19.0% had shelves for storing utensils and 34.1 % had separate dwelling for people and cattle as compared to 55.6 %, 9.1%, 6% and 18.5 % of similar practices among non-model families respectively (p&lt;0.001). Latrine availability, storage of water in a narrow necked covered container, possession of shelves for storage of utensils and fuel saving stoves declined from 96.6% to 82.3%, 92.7% to 78.6%, 33.6% to 19.1% and from 6.1% to 3%, respectively among model families after graduation (p&lt;0.01). During FGDs and in-depth interviews, socio-economic and cultural reasons were mentioned as factors that hindered the maintenance of the practices.Conclusion: Generally, model families performed better in most of the hygiene and sanitation practices than nonmodel families. The study also indicated a decline in the maintenance of certain practices among some model families

Crossing the Rift valley: using complete mitogenomes to infer the diversification and biogeographic history of ethiopian highlands Ptychadena (anura: Ptychadenidae)

The Ethiopian Highlands are considered a biodiversity hotspot, harboring a high number of endemic species. Some of the endemic species probably diversified in situ; this is, for example, the case of a monophyletic clade containing 12 known species of grass frogs of the genus Ptychadena. The different species occur at elevations ranging from 1,500 to above 3,400 m and constitute excellent models to study the process of diversification in the highlands as well as adaptations to high elevations. In this study, we sampled 294 specimens across the distribution of this clade and used complete mitogenomes and genome-wide SNP data to better understand how landscape features influenced the population structure and dispersal of these grass frogs across time and space. Using phylogenetic inference, population structure analyses, and biogeographic reconstructions, we found that the species complex probably first diversified on the south-east side of the Great Rift Valley. Later on, species dispersed to the north-west side, where more recent diversification occurred. We further demonstrate that Ptychadena species have dispersed across the Great Rift Valley at different times. Our analyses allowed for a more complete understanding of the contribution of geological events, biogeographic barriers and climatic changes as drivers of species diversification and adaptation in this important biogeographic region

Characteristics of maize cultivars in Africa: how modern are they and how many do smallholder farmers grow?

Open Access Journal; Published online: 17 March 2017Maize is the most important cereal and most widely cultivated staple that plays a key role in the food security of sub-Saharan Africa (SSA). Although some countries have achieved significant gains in maize productivity, the SSA average yields are far below what could be obtained with improved cultivars under good crop management. Low cultivar turnover is one among many contributing factors to low maize yields in SSA. At present, there is a critical knowledge gap on the identity, number, and age of maize cultivars currently grown by smallholder farmers on the continent. Results This study revealed that nearly 500 maize cultivars were grown in 13 African countries surveyed in the 2013/2014 main crop season. Sixty-nine percent of the cultivars each occupied 40% and four occupied >30% area. Approximately 32% of all the cultivars were hybrids, 23% were improved open-pollinated varieties (OPVs), and 46% were locals. Eastern Africa (EA) and southern Africa (SA) accounted for about 43 and 38%, respectively, of all the cultivars reported, whereas West Africa’s (WA) share was 19%. The average area planted to modern cultivars in the surveyed areas was estimated at 57%—with EA, SA, and WA estimates of 82, 55, and 36%, respectively; however, increased adoption was not necessarily always related to improved productivity, as the latter depends on many additional factors. Each household planted an average of 1.781 cultivars (range 1–8). The overall weighted average age of the cultivars was 15 years, with hybrids and OPVs being 13 and 18 years, respectively. Conclusions Maize variety turnover in SSA is slower than what is practiced in the USA and other world regions such as Latin America and Asia. The substantial variations among regions and countries in all parameters measured suggest a tailored approach to mitigation interventions. Findings of this current study pave the way for replacing the old cultivars with more recent releases that are tolerant or resistant to multiple stresses and are more resilient
