Evaluation of pesticide safety measures adopted by potato farmers in Chebiemit division, Elgeyo/Marakwet county, Kenya

Potato (Solanum tuberosum) is the second most important food crop after maize in Kenya. It is popular among smallholder farmers because it has short cropping cycles and large production volumes per area which fulfil both households’ food demands as well as generating income. In order to increase productivity and quality, farmers use pesticides and other agrochemicals. These pesticides if improperly handled impact negatively on the health of the users. The objective of the study was to evaluate the pesticide safety measures adopted by potato farmers in Chebiemit Division of Elgeyo/Marakwet County. Data was collected through stratified simple sampling where 323 potato farmers were administered with structured questionnaires. The data was analyzed using SPSS software. The study found out that 96% of the farmers were aware of pesticide safety labels and the level of awareness was influenced positively by education (χ2 = 4.08, p < 0.05, df = 2) and training (χ2 = 3.05, p < 0.05, df = 1). The study established that 64.7% of the farmers had cultivated the crop for more than ten years and had been using pesticides for the entire period at least thrice in every cropping cycle. The commonly used pesticides were the fungicides Ridomil and Tatamaster which have mancozeb and metalaxyl as the active ingredients. Most farmers rarely practiced safety precautions when handling, mixing and spraying chemicals and none of them wore the recommended personal protective clothing. Most of the mixing was done either in knapsacks or in basins that were also used for bathing hence increasing exposures. The study show that 58.5% of the pesticide applicators were males, 16.1% were female and children under the 14 were involved in pesticide application. The study further reported that post‐spraying safety practices among the farmers were poor since only 36.2% of the applicators bathed after spraying as compared to 69% who only washed hands and face. Females practiced better hygiene practices than males (χ2 = 31.5, p < 0.05, df = 6). Most farmers stored pesticides either in stores together with cereals or in living rooms. This study also found that 35% of the farmers disposed used pesticide containers by discarding them on the farm as compared to only 6% who disposed them by burying. The mode of disposal was influenced positively by training (χ2 = 70.2, p < 0.05, df = 3). The study found that 85.8% of the farmers who had handled pesticides had experienced pesticide poisoning but only 7.4% of them visited a health facility but the majority took milk/pain relievers or rested after spraying. The study results indicated that most potato farmers and their families were highly exposed to pesticide contamination nd poisoning due to poor pesticide safety measures. Since there is a gap in terms of training and education on pesticide safety measures, there is an urgent need to mplement training programmes to improve the knowledge, perceptions and practices of potato farmers in the study area with regard to safe handling, storage and use of pesticides.Key words: farmers, pesticide, safety, potato, Chebiemi

"Who has ever loved a drug addict? It's a lie. They think a 'teja' is as bad person": multiple stigmas faced by women who inject drugs in coastal Kenya.

BACKGROUND: A tenth of all people who inject drugs in Kenya are women, yet their social contexts and experiences remain poorly understood. This paper reports how multiple forms of stigma are experienced by women who inject drugs in coastal Kenya and the impact that they have on their ability to access essential health services. METHODS: In 2015, in-depth interviews and focus group discussions were held with 45 women who inject drugs in two coastal towns. These data were supplemented with in-depth interviews with five individual stakeholders involved in service provision to this population. Data were analyzed thematically using NVivo. RESULTS: Women who inject drugs experience multiple stigmas, often simultaneously. These included the external stigma and self-stigma of injection drug use, external gender-related stigma of being a female injecting drug user, and the external stigma of being HIV positive (i.e., among those living with HIV). Stigma led to rejection, social exclusion, low self-esteem, and delay or denial of services at health facilities. CONCLUSION: HIV and harm reduction programs should incorporate interventions that address different forms of stigma among women who inject drugs in coastal Kenya. Addressing stigma will require a combination of individual, social, and structural interventions, such as collective empowerment of injecting drug users, training of healthcare providers on issues and needs of women who inject drugs, peer accompaniment to health facilities, addressing wider social determinants of stigma and discrimination, and expansion of harm reduction interventions to change perceptions of communities towards women who inject drugs

Analysis of markets for African leafy vegetables within Nairobi ant its environs and implications for on-farm conservation of biodiversity

African Leafy Vegetables (ALVs) are important sources of essential macro and micro-nutrients. In addition they offer a source of livelihood when marketed, and also contribute to crop biodiversity. Despite these positive aspects, only a few ALVs are grown, marketed and consumed in Kenya. This study analyses the ALV market in Nairobi and the neighbouring areas, highlighting the factors that enable or inhibit its development. Furthermore, the study determined different factors influencing inter- and intra-specific on-farm biodiversity, with a focus on the role of ALV market development

Impact of agribusiness empowerment interventions on youth livelihoods: insight from Africa

Open Access JournalThis study generates evidence to understand the impact of agribusiness empowerment programmes on youth livelihoods in developing countries based on the ENABLE-TAAT programme implemented in Kenya, Nigeria, and Uganda. A multistage sampling technique was used in obtaining primary agribusiness-level data from a sample of 1435 young agripreneurs from the study countries. An Endogenous Treatment Effect Regression (ETER) model was used to assess the impact of programme participation on youth livelihoods (income and food security). Results show that participation significantly increased youth's agripreneurship income by 7% and improved food security by 75% for the pooled analysis. The country disaggregation results show that participation led to a 54% and 37% increase in the income of participants in Nigeria and Uganda, respectively. Also, positive and significant impacts were obtained for food security in the two East African countries. These findings suggest policy interventions or programmes focusing on youth agribusiness empowerment, particularly those that target young actors along different agricultural value chains. The study also suggests interventions geared towards mitigating constraints to credit access and productive resources by young agripreneurs to ease barriers to working capital and business innovation

Assessment of willingness-to-pay for Aflasafe KE01, a native biological control product for aflatoxin management in Kenya

Open Access Article; Published online: 07 Oct 2020Contamination of key staples with aflatoxins compromises the quality of food and feed, impedes trade, and negatively affects the health of consumers whereas acute exposure can be fatal. This study used the Contingent Valuation Method (CVM) on a sample of 480 farmers in counties prone to aflatoxin contamination to assess the willingness to pay (WTP) by farmers for Aflasafe KE01, a promising biological control product for the management of aflatoxin contamination of key staples in Kenya, compare its cost with that of a similar product in use in Nigeria, and determine factors likely to affect its adoption. Four hundred and eighty households from four counties identified as aflatoxin hotspots in Kenya were purposively selected and interviewed using a semi-structured questionnaire. The mean WTP per kilogram of Aflasafe KE01, using Contingent Valuation Method in the four counties ranged from Kenya Shillings (Ksh) 113 to 152/kg compared to a cost of Ksh. 130/kg, the price of a similar product, AflasafeTM, in Nigeria. Factors that positively influenced farmers’ WTP included information from crop extension services and access to credit. To facilitate the adoption of Aflasafe KE01 or any other biocontrol product in Kenya and elsewhere, there is a need for increased education efforts through extension services to farmers about aflatoxins. Strategies to ensure that the biocontrol product is integrated into the credit scheme of the technological packages to farmers need to be considered

Can young agripreneurs improve their skills through agripreneurship empowerment programmes? Evidence from Africa

Open Access JournalThis article examined the driving forces behind young agripreneurs’ participation in agripreneurship empowerment programmes and estimates the causal impact of programme participation on agripreneurship skills using data from a random cross-section sample of 1435 young agripreneurs in Kenya, Nigeria, and Uganda. Specifically, the study took evidence from the youth component of the African Development Bank Technologies for African Agricultural Transformation (TAAT) programme, Empowering Novel Agribusiness-Led Employment (ENABLE). An endogenous switching model was used to identify factors that significantly informed participation decisions and assess the programme’s impact on youth agripreneurship skills. Age, education, agripreneurship experience, business level, current residence, and training perception significantly influenced participation. Even though both programme participants and non-participants had high agripreneurship skills scores, participants had higher scores across the three countries than non-participants. The causal impact estimation from the switching regression model also indicates that participation has a positive and significant impact on agripreneurship skills, which implies that the higher score achieved by participants could be attributed to their involvement in the ENABLE-TAAT programme. These results suggest raising awareness of youth agribusiness empowerment programmes and encouraging youth to participate more actively. Additionally, the result suggests the need to implement strategies that could change young people’s negative perception of agricultural interventions for increased participation

Assessing food security among young farmers in Africa: evidence from Kenya, Nigeria, and Uganda

Open Access JournalFood insecurity remains a serious challenge for many households in Africa and the situation is even more prevalent among young people. However, there is a dearth of empirical evidence on youth food security status in Africa. We assessed the level and determinants of food security among young farmers in Africa. We adopted a multi-stage sampling technique to select 400, 429, and 606 young farmers in Kenya, Nigeria, and Uganda, respectively. Individual food consumption was assessed following a 7 days recall method. The Food Consumption Score, which combines dietary diversity and consumption frequency was used to assess food security status while the determinants of food security were identified using a logistic regression model. Results suggest low dietary diversity across the three countries. Also, the majority of the respondents had an unacceptable food consumption score, suggesting that despite being food producers, young farmers are still food insecure. The odds of being food secure was positively determined by access to extension services, participation in the ENABLE TAAT business incubation programme, and access to market information but, negatively by access to credit, number of employees, Covid-19 pandemic, and location. Additionally, the food security status of young female farmers was positively influenced by age, suggesting that younger youths are less food secure compared to older ones. These results suggest that more efforts should be directed towards improving the food security of young African farmers and that policy- and programme-level interventions should support access to extension services, market information, and land. Additionally, more investments should be directed towards developing need-based agribusiness incubation programmes with an effort to scale existing programmes beyond the regular one-time period

Configuration of anchorage holes affects fixation of the acetabular component in cemented total hip replacement - a finite element study

Our survey of current practice among UK orthopaedic surgeons shows wide variations in fixation techniques. The aim of this study is to investigate the effect of drilling different configurations of anchorage holes in the acetabulum on implant stability. To avoid variables that could incur during in-vitro testing, we used commercially-available COSMOS finite element analysis package to investigate the stress distributions, deformations, and strains on the cement mantle when drilling three large anchorage holes and six smaller ones, with straight and rounded cement pegs. The results, which are in line with our in-vitro studies on simulated reconstructed acetabulae, indicate better stability of the acetabular component when three larger holes than six smaller holes are drilled and when the necks of the anchorage holes are rounded. The longevity of total hip replacements could be improved by drilling three large anchorage holes, rather than many smaller ones, as initially proposed by Charnley

The first genome sequence of Anopheles squamous from Macha, Zambia [version 1; peer review: 2 approved]

Despite efforts to minimize the impacts of malaria and reduce the number of primary vectors, malaria has yet to be eliminated in Zambia. Understudied vector species may perpetuate malaria transmission in pre-elimination settings. Anopheles squamosus is one of the most abundantly caught mosquito species in southern Zambia and has previously been found with Plasmodium falciparum sporozoites, a causal agent of human malaria. This species may be a critical vector of malaria transmission, however, there is a lack of genetic information available for An. squamosus. We report the first genome data and the first complete mitogenome (Mt) sequence of An. squamosus. The sequence was extracted from one individual mosquito from the Chidakwa area in Macha, Zambia. The raw reads were obtained using Illumina Novaseq 6000 and assembled through NOVOplasty alignment with related species. The length of the An. squamosus Mt was 15,351 bp, with 77.9 % AT content. The closest match to the whole mitochondrial genome in the phylogenetic tree is the African malaria mosquito, Anopheles gambiae. Its genome data is available through National Center for Biotechnology Information (NCBI) Sequencing Reads Archive (SRA) with accession number SRR22114392. The mitochondrial genome was deposited in NCBI GenBank with the accession number OP776919. The ITS2 containing contig sequence was deposited in GenBank with the accession number OQ241725. Mitogenome annotation and a phylogenetic tree with related Anopheles mosquito species are provided
