Roles of Local Governance Institutions and Promotion of Urban Agriculture Practices in Western Kenya

The role of local government institution and especially institutional structures and political culture often shape government performance including livelihood supporting activities such as Urban Agriculture (UA). The changing population pattern orchestrated by the spread of urbanization has resulted into a rise in poverty and food demand, necessitating UA. However, there seem to be limited documentation with regard to how local governance institutions influence and promote UA practices. The purpose of the study was to assess how roles of local governance institutions influence promotion of urban agriculture practices in Western Kenya. The specific objectives were to investigate the influence of economic, social and environmental roles of institutions, and the relationship between county government institutions roles and urban agriculture practice. Cross sectional survey design was adopted on a target population of 440 urban farmers (Eldoret: N=137; Kakamega: N=145; Kisumu: N=158) identified through the assistance of County Agricultural officers in the three towns. A sample size of 205 respondents (Eldoret=63; Kakamega=68; Kisumu=74) was obtained using stratified technique. Questionnaire and Key Informant interviews were used for data collection. Inferential statistics using Pearson Product Moment Correlation Coefficient was used in data analysis. Results showed that the department of agriculture, livestock and fisheries was the most important institution on promotion of urban agriculture in Kisumu (40.0%), Kakamega (42.2%) and Eldoret (64.8%). There was there was a moderate positive correlation (n=205; r =.532; p <.05) between role of county government institutions and UA practices which was statistically significant

Combining host plant resistance, selective insecticides, and biological control agents for integrated management of Tuta absoluta

Combination of pest management strategies that minimize pesticide use and conserve natural enemies is important for a sustainable environment. Overreliance on synthetic insecticides in the management of Tuta absoluta has led to pesticide resistance leading to difficulties in managing the pest. In this regard, alternative measures need to be put in place to reduce the effects of this pest. ,e objective of this study was, therefore, to assess the effectiveness of host plant resistance, biological control, and selective insecticides when used in combination, in the management of T. absoluta in tomato production. ,e study was set up in a greenhouse in a completely randomized design involving two tomato varieties, an insecticide (chlorantraniliprole), and a biological control agent(Macrolophus pygmaeus), applied singly or in combination. Data were collected on T. absoluta damage from the lower, intermediate, and upper leaves. ,e results from this study show that a combination of insecticide with a moderately resistant variety had a significantly lower T. absoluta damage as compared with a susceptible variety combined with an insecticide. However, the moderately resistant variety when combined with insecticide showed no effect when the biological control agent was added. ,e susceptible variety significantly reduced T. absoluta damage when combined with the biological control agent. ,ese results indicate that treatment combinations in insect pest management can be utilized. ,e present study results indicate that using a moderately resistant variety (Riogrande VF) in combination with the insecticide chlorantraniliprole (Coragen®) and a susceptible variety (Pesa F1) in combination with the biological control agent (M. pygmaeus) can improve T. absoluta management. Under good habitat management, the susceptible variety will perform equally as the moderately resistant variety due to suppression of the T. absoluta populations by natural enemies. ,ese findings show the importance of environmental conservation both by enhancing natural enemy abundance and use of selective insecticide in the management of T. absoluta in tomato production. Combinations in this present study are likely to reduce insecticide doses, thereby reducing the cost of production and enhancing environmental compatibility with natural enemies

Mathematics teacher agency

Neoliberal policies dominate in many parts of the world, setting a frame within which education practices are frequently constrained. In mathematics, perhaps more than other subjects, these constraints seem to be more keenly felt, not least because of the economic value placed on mathematics expertise and the related effects of performativity and accountability. In this symposium we explore potential sources of support that may enable mathematics teachers to challenge orthodox practices, facilitate creative responses to and/or rejections of policy constraints as they negotiate agency over their practice and their learning

Elevated ozone and carbon dioxide affects the composition of volatile organic compounds emitted by Vicia faba (L.) and visitation by European orchard bee (Osmia cornuta)

Recent studies link increased ozone (O3) and carbon dioxide (CO2) levels to alteration of plant performance and plant-herbivore interactions, but their interactive effects on plant-pollinator interactions are little understood. Extra floral nectaries (EFNs) are essential organs used by some plants for stimulating defense against herbivory and for the attraction of insect pollinators, e.g., bees. The factors driving the interactions between bees and plants regarding the visitation of bees to EFNs are poorly understood, especially in the face of global change driven by greenhouse gases. Here, we experimentally tested whether elevated levels of O3 and CO2 individually and interactively alter the emission of Volatile Organic Compound (VOC) profiles in the field bean plant (Vicia faba, L., Fabaceae), EFN nectar production and EFN visitation by the European orchard bee (Osmia cornuta, Latreille, Megachilidae). Our results showed that O3 alone had significant negative effects on the blends of VOCs emitted while the treatment with elevated CO2 alone did not differ from the control. Furthermore, as with O3 alone, the mixture of O3 and CO2 also had a significant difference in the VOCs’ profile. O3 exposure was also linked to reduced nectar volume and had a negative impact on EFN visitation by bees. Increased CO2 level, on the other hand, had a positive impact on bee visits. Our results add to the knowledge of the interactive effects of O3 and CO2 on plant volatiles emitted by Vicia faba and bee responses. As greenhouse gas levels continue to rise globally, it is important to take these findings into consideration to better prepare for changes in plant-insect interactions

Summary Brief: Heifer study on climate-smart agriculture adoption rates amongst goat farming households in three districts of Nepal and the impact on key environmental and economic indicators

This info brief provides an executive overview of the research methods and key finding of a series of information briefs. The briefs were developed to assess the role of Heifer Nepal programming in supporting the adoption of Climate-Smart Agriculture (CSA) practices amongst Heifer supported goat cooperatives, and their impact on a range of environmental and economic indicators. The recommendations of the analysis are intended to further strengthen the integration of climate change considerations into Heifer Nepal’s programming, with the goal of raising overall household incomes amongst supported households through means that have minimal negative impact on the environment. The research was conducted in three districts encompassing the main agro-ecological contexts in which Heifer Nepal works

Mortality trends in the era of antiretroviral therapy: evidence from the Network for Analysing Longitudinal Population based HIV/AIDS data on Africa (ALPHA)

Background:The rollout of antiretroviral therapy (ART) is one of the largest public health interventions in Eastern and Southern Africa of recent years. Its impact is well described in clinical cohort studies, but population-based evidence is rare.Methods:We use data from seven demographic surveillance sites that also conduct community-based HIV testing and collect information on the uptake of HIV services. We present crude death rates of adults (aged 15–64) for the period 2000–2011 by sex, HIV status, and treatment status. Parametric survival models are used to estimate age-adjusted trends in the mortality rates of people living with HIV (PLHIV) before and after the introduction of ART.Results:The pooled ALPHA Network dataset contains 2.4 million person-years of follow-up time, and 39114 deaths (6893 to PLHIV). The mortality rates of PLHIV have been relatively static before the availability of ART. Mortality declined rapidly thereafter, with typical declines between 10 and 20% per annum. Compared with the pre-ART era, the total decline in mortality rates of PLHIV exceeds 58% in all study sites with available data, and amounts to 84% for women in Masaka (Uganda). Mortality declines have been larger for women than for men; a result that is statistically significant in five sites. Apart from the early phase of treatment scale up, when the mortality of PLHIV on ART was often very high, mortality declines have been observed in PLHIV both on and off ART.Conclusion:The expansion of treatment has had a large and pervasive effect on adult mortality. Mortality declines have been more pronounced for women, a factor that is often attributed to women's greater engagement with HIV services. Improvements in the timing of ART initiation have contributed to mortality reductions in PLHIV on ART, but also among those who have not (yet) started treatment because they are increasingly selected for early stage disease

Coaching Community Health Volunteers in Integrated Community Case Management Improves the Care of Sick Children Under-5: Experience from Bondo, Kenya

Background: Shortages of healthcare workers is detrimental to the health of communities, especially children. This paper describes the process of capacity building Community Health Volunteers (CHVs) to deliver integrated preventive and curative package of care of services to manage common childhood illness in hard-to-reach communities in Bondo Subcounty, Kenya. Methods: A pre-test/post-test single-group design was used to assess changes in knowledge and skills related to integrated community case management (iCCM) among 58 Community Health Volunteers who received a six-day iCCM clinical training and an additional 3-week clinical coaching at health facilities. Thereafter, community health extension workers and health managers provided supportive supervision over a six-month period. Skills were assessed before the six-day training, during coaching, and after six months of iCCM implementation. Results: CHVs knowledge assessment scores improved from 54.5% to 72.9% after the six-day training (p < 0.001). All 58 CHVs could assess and classify fever and diarrhoea correctly after 3–6 weeks of facility-based clinical coaching; 97% could correctly identify malnutrition and 80%, suspected pneumonia. The majority correctly performed four of the six steps in malaria rapid diagnostic testing. However, only 58% could draw blood correctly and 67% dispose of waste correctly after the testing. The proportion of CHV exhibiting appropriate skills to examine for signs of illness improved from 4% at baseline to 74% after 6 months of iCCM implementation, p < 0.05. The proportion of caregivers in intervention community units who first sought treatment from a CHV increased from 2 to 31 percent (p < 0.001). Conclusions: Training and clinical coaching built CHV’s skills to manage common childhood illnesses. The CHVs demonstrated ability to follow the Kenya iCCM algorithm for decision-making on whether to treat or refer a sick child. The communities’ confidence in CHVs’ ability to deliver integrated case management resulted in modification of care-seeking behaviour

Evaluation of RTS,S/AS02A and RTS,S/AS01B in Adults in a High Malaria Transmission Area

This study advances the clinical development of the RTS,S/AS01B candidate malaria vaccine to malaria endemic populations. As a primary objective it compares the safety and reactogenicity of RTS,S/AS01B to the more extensively evaluated RTS,S/AS02A vaccine.A Phase IIb, single centre, double-blind, controlled trial of 6 months duration with a subsequent 6 month single-blind follow-up conducted in Kisumu West District, Kenya between August 2005 and August 2006. 255 healthy adults aged 18 to 35 years were randomized (1ratio1ratio1) to receive 3 doses of RTS,S/AS02A, RTS,S/AS01B or rabies vaccine (Rabipur; Chiron Behring GmbH) at months 0, 1, 2. The primary objective was the occurrence of severe (grade 3) solicited or unsolicited general (i.e. systemic) adverse events (AEs) during 7 days follow up after each vaccination.Both candidate vaccines had a good safety profile and were well tolerated. One grade 3 systemic AE occurred within 7 days of vaccination (RTS,S/AS01B group). No unsolicited AEs or SAEs were related to vaccine. A marked increase in anti-CS antibody GMTs was observed post Dose 2 of both RTS,S/AS01B (31.6 EU/mL [95% CI: 23.9 to 41.6]) and RTS,S/AS02A (16.7 EU/mL [95% CI: 12.9 to 21.7]). A further increase was observed post Dose 3 in both the RTS,S/AS01B (41.4 EU/mL [95% CI: 31.7 to 54.2]) and RTS,S/AS02A (21.4 EU/mL [95% CI: 16.0 to 28.7]) groups. Anti-CS antibody GMTs were significantly greater with RTS,S/AS01B compared to RTS,S/AS02A at all time points post Dose 2 and Dose 3. Both candidate vaccines produced strong anti-HBs responses. Vaccine efficacy in the RTS,S/AS01B group was 29.5% (95% CI: -15.4 to 56.9, p = 0.164) and in the RTS,S/AS02A group 31.7% (95% CI: -11.6 to 58.2, p = 0.128).Both candidate malaria vaccines were well tolerated over a 12 month surveillance period. A more favorable immunogenicity profile was observed with RTS,S/AS01B than with RTS,S/AS02A.Clinicaltrials.gov NCT00197054
