Gender Roles and Constraints in Beekeeping: A Case from Kitui County, Kenya
Beekeeping is a form of agriculture that
involves management of wild or domesticated
bee colonies for production of
honey and wax. Generally, in Kenya,
women perform most of the agricultural
activities (GOK, 2005; Oduol et al., 2013).
Even though they play a major role in
these activities, they end up receiving a
fraction of the income generated. In most
of the African countries, beekeeping has
often been a male-dominated enterprise
(Nel & Illgner, 2004; Ogaba & Akongo,
2001; Shackleton, Paumgarten, Kassa,
Husselman, & Zida, 2011). However, with
intervention from rural development
agencies, a change in this practice could
occur..
Risk of Injection-Site Abscess among Infants Receiving a Preservative-Free, Two-Dose Vial Formulation of Pneumococcal Conjugate Vaccine in Kenya.
There is a theoretical risk of adverse events following immunization with a preservative-free, 2-dose vial formulation of 10-valent-pneumococcal conjugate vaccine (PCV10). We set out to measure this risk. Four population-based surveillance sites in Kenya (total annual birth cohort of 11,500 infants) were used to conduct a 2-year post-introduction vaccine safety study of PCV10. Injection-site abscesses occurring within 7 days following vaccine administration were clinically diagnosed in all study sites (passive facility-based surveillance) and, also, detected by caregiver-reported symptoms of swelling plus discharge in two sites (active household-based surveillance). Abscess risk was expressed as the number of abscesses per 100,000 injections and was compared for the second vs first vial dose of PCV10 and for PCV10 vs pentavalent vaccine (comparator). A total of 58,288 PCV10 injections were recorded, including 24,054 and 19,702 identified as first and second vial doses, respectively (14,532 unknown vial dose). The risk ratio for abscess following injection with the second (41 per 100,000) vs first (33 per 100,000) vial dose of PCV10 was 1.22 (95% confidence interval [CI] 0.37-4.06). The comparator vaccine was changed from a 2-dose to 10-dose presentation midway through the study. The matched odds ratios for abscess following PCV10 were 1.00 (95% CI 0.12-8.56) and 0.27 (95% CI 0.14-0.54) when compared to the 2-dose and 10-dose pentavalent vaccine presentations, respectively. In Kenya immunization with PCV10 was not associated with an increased risk of injection site abscess, providing confidence that the vaccine may be safely used in Africa. The relatively higher risk of abscess following the 10-dose presentation of pentavalent vaccine merits further study
Characterization of Sorghum Production and Marketing Systems in Eastern Province, Kenya: Sorghum for Multi-Use (SMU) Baseline Survey Report. Working Paper Series no. 53
A baseline survey was conducted to characterize the sorghum production and marketing system in Eastern Province of Kenya and, in combination with other follow up rapid assessment fora with relevant stakeholders, to aid the setting of project performance targets and implementation of interventions including establishment of a commercial pilot sorghum value chain for testing and upgrading. Eight SMU mandate districts/ sub-counties were grouped into 4 technology-adoption clusters out of which 480 farm households were randomly selected from the most important sorghum producing sub-locations. Women were managers in about 50% of the household farms and about 80% of all farmers reported farming as their main occupation. The mean farm size was 7.8 acres out of which 50% and 30% was under crop and sorghum production, respectively. Farms managed by women were smaller than those managed by men. The farm households exhibited a variable dependency ratio with the women managed farms showing significantly higher dependency ratio (1.3) than male managed farms (0.9) – meaning that labor availability was a more critical constraint in women managed farms. Therefore, labor-saving (mechanization, etc) and land-saving technologies (higher yielding varieties, fertilizer, tied ridges, etc) would enhance sorghum production. The other constraints were poor production and market infrastructure and information asymmetry in which women farmers, with less access to production information than their male counterparts, reporting more dependence on “other farmers” for agricultural information. Majority of farmers depended on agro-dealers, radio and other farmers for agricultural information. Hence innovative information channels such as use of agro-dealers, radio, training of trainers (TOTs) and farmer innovation platforms should be strengthened. Although double the number of male than female farmers reported purchase of seed from markets, use of recycled sorghum seed was the norm by the majority of farmers while use of inorganic fertilizer on sorghum was nil. Sorghum grain production per household was 360 kg out of which 65% was sold, 30% consumed while 5% was kept for seed. Sorghum yield was highest in Mwingi (501 kg per acre) and lowest in Kibwezi (216 kg per acre). Farmers who reported use of farmyard manure reported 35% more sorghum grain yield than those who had not used farmyard manure. Furthermore higher household production and productivity was positively correlated with the practice of row planting and use of soil and water conservation technologies, including dry or early planting. The primary use of sorghum grain at the household level was for making porridge and “ugali” (stiff porridge) while value addition activities were limited to milling of grain or mixtures of sorghum and other grains, wet milling and dehulling. The most important sorghum product marketed was grain, which was bought by brokers, rural assemblers, urban traders and consumers, with the consumers offering the farmers highest prices. Low grain price was the most important marketing constraint and hence, as well as improving market linkage for grain, diversifying value added products of sorghum for household level use and for commercialization would help create demand for sorghum grain and improve prices. Although awareness of collective grain marketing was high, farmers’ participation was minimal and their participation was constrained by low grain production (36%), low grain quality (30%), delayed payment for delivered grain (29%) and restriction on free grain marketing (25%)
Potato cyst nematodes: a new threat to potato production in east Africa
Open Access Journal; Published online: 25 May 2020Potato cyst nematodes (PCN), such as Globodera rostochiensis and Globodera pallida, are quarantine restricted pests of potato causing major yield and financial losses to farmers. G. rostochiensis was first reported from Kenya’s key potato growing area in 2015. We sought to determine the diversity, prevalence and distribution of PCN species across the country by conducting a country-wide survey between 2016 and 2018, which included a more focused, follow-up assessment in three key potato growing counties. A total of 1,348 soil samples were collected from 20 potato growing counties. Information regarding local potato farming practices, potato cultivar use, their diversity and availability was also recorded. PCN cysts were obtained from 968 samples (71.8%) in all the counties surveyed, with Nyandarua County recording the highest PCN field-incidence at 47.6%. The majority of PCN populations, 99.9%, were identified as G. rostochiensis, while G. pallida was recovered from just one field, in a mixed population with G. rostochiensis. Inconsistencies in PCR amplification efficiency was observed for G. rostochiensis using the recommended EPPO primers, compared with ITS primers AB28/TW81, indicating that this protocol cannot be entirely relied upon to effectively detect PCN. Egg density in Nyandarua County varied between 30.6 and 158.5 viable eggs/g soil, with an average egg viability of 78.9 ± 2.8% (min = 11.6%, max = 99.9%). The PCN-susceptible potato cultivar named Shangi was the most preferred and used by 65% of farmers due to its shorter dormancy and cooking time, while imported cultivars (Destiny, Jelly, Manitou, and Markies) with resistance to G. rostochiensis were used by 7.5% of farmers due to unavailability and/or limited access to seeds. Thus, most farmers preferred using their own farm-saved seeds as opposed to purchasing certified seeds. Establishing the distribution and prevalence of PCN and elucidating the local farming practices that could promote the spread of PCN is a necessary precursor to the implementation of any containment or management strategy in the country and ultimately across the region
Gelsolin Plays a Role in the Actin Polymerization Complex of Hair Cell Stereocilia
A complex of proteins scaffolded by the PDZ protein, whirlin, reside at the stereocilia tip and are critical for stereocilia development and elongation. We have shown that in outer hair cells (OHCs) whirlin is part of a larger complex involving the MAGUK protein, p55, and protein 4.1R. Whirlin interacts with p55 which is expressed exclusively in outer hair cells (OHC) in both the long stereocilia that make up the stereocilia bundle proper as well as surrounding shorter microvilli that will eventually regress. In erythrocytes, p55 forms a tripartite complex with protein 4.1R and glycophorin C promoting the assembly of actin filaments and the interaction of whirlin with p55 indicates that it plays a similar role in OHC stereocilia. However, the components directly involved in actin filament regulation in stereocilia are unknown. We have investigated additional components of the whirlin interactome by identifying interacting partners to p55. We show that the actin capping and severing protein, gelsolin, is a part of the whirlin complex. Gelsolin is detected in OHC where it localizes to the tips of the shorter rows but not to the longest row of stereocilia and the pattern of localisation at the apical hair cell surface is strikingly similar to p55. Like p55, gelsolin is ablated in the whirler and shaker2 mutants. Moreover, in a gelsolin mutant, stereocilia in the apex of the cochlea become long and straggly indicating defects in the regulation of stereocilia elongation. The identification of gelsolin provides for the first time a link between the whirlin scaffolding protein complex involved in stereocilia elongation and a known actin regulatory molecule

Reproductive health and lifestyle factors associated with health-related quality of life among perinatally HIV-infected adolescents in Uganda
Background
With increased survival of perinatally HIV - infected adolescents due to antiretroviral therapy (ART), the focus of HIV care has shifted to health-related quality of life (HRQoL) as a measure of disease progression, effects of ART co-morbidity and prognosis. We assessed factors associated with better HRQoL in perinatally HIV -infected adolescents in Uganda by determining the associations between sexual and reproductive health (SRH) or lifestyle experiences on HRQoL.
Methods
In a cross-sectional study, data on SRH, lifestyle experiences, socio demographic factors, communication with parents on sexuality and satisfaction of SRH services in ART clinics were collected from 614 HIV perinatally infected adolescents aged 10–19 using an interviewer-administered survey questionnaire. HRQoL data were collected using the Medical Outcomes Study HIV Health Survey instrument (MOS-HIV). Factors associated with better HRQoL were analysed using multiple logistic regression.
Results
The mean age was 16.2 ± 2.1 years, 362 (58.8 %) were females and 210 (34.2 %) were sexually active. Adolescents on ART were twice likely to present with better physical health (AOR = 2.07, 95 % CI: 1.24–3.46) and four times more likely to present with better mental health (AOR = 3.9, 95 % CI: 2.22–6.92) than those who were not on ART. There were no statistically significant associations between SRH (ever had sex, ever been pregnant, condom use, contraceptive use) or life style factors and physical health or mental health. Those with secondary or tertiary education were more likely to present with a better mental health (AOR = 5.3, 95 % CI: 1.86–15.41) compared those who had attained primary or no education. Participants who desired to have a child in future more likely (AOR 1.7, 95 % CI: 1.05–3.00) to present with a better mental health. Lack of communication with guardians on sexuality (AOR = 0.6, 95 % CI: 0.40–0.89), or dissatisfaction with SRH services (AOR 0.34, 95 % CI: 0.18–0.62) were associated with poorer mental health.
Conclusion
Among perinatally HIV-infected adolescents in Uganda, being on ART was associated with better physical and mental health while lack of communication with guardians on sexuality or dissatisfaction with SRH services was associated with poor mental health. Adolescents with pregnancy intentions were more likely to have a better mental health
Wetlands for wastewater treatment and subsequent recycling of treated effluent : a review
Due to water scarcity challenges around the world, it is essential to think about non-conventional water resources to address the increased demand in clean freshwater. Environmental and public health problems may result from insufficient provision of sanitation and wastewater disposal facilities. Because of this, wastewater treatment and recycling methods will be vital to provide sufficient freshwater in the coming decades, since water resources are limited and more than 70% of water are consumed for irrigation purposes. Therefore, the application of treated wastewater for agricultural irrigation has much potential, especially when incorporating the reuse of nutrients like nitrogen and phosphorous, which are essential for plant production. Among the current treatment technologies applied in urban wastewater reuse for irrigation, wetlands were concluded to be the one of the most suitable ones in terms of pollutant removal and have advantages due to both low maintenance costs and required energy. Wetland behavior and efficiency concerning wastewater treatment is mainly linked to macrophyte composition, substrate, hydrology, surface loading rate, influent feeding mode, microorganism availability, and temperature. Constructed wetlands are very effective in removing organics and suspended solids, whereas the removal of nitrogen is relatively low, but could be improved by using a combination of various types of constructed wetlands meeting the irrigation reuse standards. The removal of phosphorus is usually low, unless special media with high sorption capacity are used. Pathogen removal from wetland effluent to meet irrigation reuse standards is a challenge unless supplementary lagoons or hybrid wetland systems are used
Joint management of shared resources as an alternative approach for addressing maritime boundary disputes : the Kenya-Somalia maritime boundary dispute
Socio-economic security has motivated African states to explore natural resources in areas of overlapping maritime claims. However, Africa’s maritime boundaries are characterized by unresolved disputes. Resolution of these disputes is time-consuming, expensive and can undermine the state’s ability to exploit natural resources. The Somalia and Kenya maritime dispute under litigation with the International Court of Justice demonstrates the continental commitment to peaceful resolution. Citing cases from across Africa, we discuss outright delimitation or Joint Management Zones (JMZs) as means to address disputes over shared resources, particularly transboundary fisheries, which have received little attention. Reframing the Kenya-Somalia maritime dispute resolution process as cooperation over fisheries management will have spill-over effects into greater diplomatic relations. Fish do not abide by maritime boundaries. As such, we posit that the peaceful resolution of maritime boundary disputes lies in Africa’s ability to consider settlements by way of JMZs to motivate sustainable use of natural resources.PostprintPeer reviewe
