Macrolepiota Aberdarense, a New Edible Mushroom from Kenya
(Current Research in Environmental & Applied Mycology (Journal of Fungal Biology), 2018-03-15) Mbaluto, C; Runo, S; Wanyoike, W; Onyango, C; Kimani, W; Jagger, H; Otieno, DO
A new Macrolepiota species from the Aberdare Forest in Kenya is described and illustrated. The larger basidiomata with yellow brownish to brownish granular squamules, distinct umbo, larger basidia and smaller ellipsoid basidiospores form remarkable features that separate this species from previously published members belonging to the genus Macrolepiota. The phylogenetic analyses based on ITS-rDNA sequences further supported this distinction.
Effect of Logistic Service Reliability Capability on Performance of Manufacturing Firms: The Moderating Role of Supply Chain Linkages
(African Journal of Education, Science and Technology, 2018-12) Kimitei E.; Chepkwony J.; Lagat C.; Koskei D.
Business organizations striving to improve their performance rely on several capabilities including logistic service reliability capability. However, there is also a need to understand how external variables may moderate the effect of logistic capabilities and performance. This study evaluated the moderating effect of supply chain linkages on the relationship between logistic service reliability capability and firm performance of manufacturing firms in Kenya. The study anchored on explanatory research design. A sample size of 442 firms was selected using stratified and simple random sampling approaches. The study established that logistic service reliability capability positively and significantly affects firm performance, subject to moderation by supply chain linkages. For the design of management system in a firm, there is need to integrate and improve the overall effects of logistic service reliability capability by incorporating supply chain linkages in the model. There is need for firm managers to understand and find ways to effectively manage the interactions between logistic service reliability capability and supply chain linkages in order to improve performance and meet the customer requirements satisfactorily. In many manufacturing firms especially in developing countries such interactions are rarely studied.
Prevalence, determinants and economic losses due to echinococcosis in cattle, sheep and goats slaughtered in Webuye abattoir, Bungoma county, Kenya.
(Moi University, 2018-10) Wasike, Jairus Wanga
Title: Prevalence, determinants and economic losses due to Echinococcosis in cattle, sheep and goats slaughtered in Webuye abattoir, Bungoma County, Kenya Background: Cystic Echinococcosis is a neglected zoonosis, but is of great veterinary, Public health and economic importance. An account of Echinococcosis in cattle, sheep and goats slaughtered in Webuye abattoir, presence of roaming dogs in Webuye town, practices, minimal knowledge by people on Echinococcosis and economic loss from organ condemnation due to Echinococcosis justified carrying out the study. Objective: To determine the prevalence, determinants and economic losses due to Echinococcosis in cattle, sheep and goats slaughtered at Webuye abattoir. Methods: Study area was Webuye abattoir and Cross sectional study was used in March 15th to 15th April 2015. All cattle, sheep and goats slaughtered were inspected for the presence of Echinococcus cysts. Cysts encountered were recorded and further subjected to fertility and viability tests. A questionnaire whose purpose was to determine risk factors was administered to 15 butchers and 9 flayers. Percentages of Echinococcosis cases were calculated. Economic loss due to organ condemnation was calculated by taking the weight of individual organ and multiplying by its prevailing market value. Statistical package for Social Scientists version 20 and MS Excel were used in data analysis where frequencies and percentages were the outputs. Data was presented using tables, narratives, frequencies, percentages and charts. Results: A total of 134 head of cattle, 126 sheep and 49 goats were slaughtered and inspected. Hydatid cysts were detected in 31 (23.1%) cattle, 4 (3.2%) sheep and none in goats. A total of 111, 9 and 0 cysts were detected in cattle, sheep and goats respectively. In cattle 89 cysts were fertile and 38 were viable. In sheep 9 cysts were fertile and viable, that indicates risk of transmission. On risk factors, 29.5% of respondents fed dogs on condemned offal, 33% did not confine their dogs, and 37.5% did not deworm their dogs and 54% admitted that no inspection was carried out to meat of livestock slaughtered at home. The total annual economic loss from organs condemnation was estimated to be Ksh. 195, 300 (1,884.2 US Dollars). That was substantial amount. Conclusion: Prevalence of Echinococcosis in cattle was moderate and low in sheep. Public knowledge on Echinococcosis and its control was low. Annual Economic loss from organ condemnation was substantial. Recommendation: Based on these study findings, abattoir public health measures should be tightened. Regular Public health education awareness programs on Echinococcosis and its control should be conducted. Further research is needed to assess the prevalence of Echinococcosis in humans.
Beef value chain analysis and climate change adaptation and investment options in the semi-arid lands of northern Kenya
(Elsevier, 2020-10-01) Ndiritu, S. Wagura
The purpose of this paper is to examine the beef value chain and identify climate change adaptation and investment options in the semi-arid areas of northern Kenya. The research uses an innovative approach to value chain analysis, namely the three-step Value Chain Analysis for Resilience in Drylands (VC-ARID) that considers the specific characteristics of semi-arid systems. All the respondents interviewed along the value chain have perceived changes in rainfall, temperature and climate extremes – especially drought – over the past 15 years and have experienced the impacts of these changes on their livestock. The findings show that pastoralist producers need to invest in fattening programmes at their ranches or via feedlots to increase the quality of the beef they produce. There is significant potential to improve the fattening stage in the value chain, since it would contribute towards meeting demand in the expanding high-end markets that require finished, top-quality meats.

(International Journal of Science and Research Archive, 2024-12-18) Rogito, Jeremiah Magoma; Makhanu, Everlyne; Rogito, Jeremiah Magoma; Makhanu, Everlyne
The study investigated the relationship between land accessibility and youth participation in the agricultural value chain in Kakamega County, Kenya. Utilizing a stratified questionnaire for data collection from 240 respondents, chosen through stratified and simple random sampling, the research analyzed data to generate frequencies, percentages, and correlations. Results showed that limited access to land is a significant barrier for youth involvement in agriculture, impacting all stages of the value chain except consumption. This study is novel in its comprehensive analysis of the entire agricultural value chain, from production to consumption, and its focuses on the youth, a crucial demographic in Kenya. The findings highlight the importance of land accessibility for the youth's active participation and the potential economic benefits thereof. The insights are valuable for policymakers and donor organizations in crafting strategies to improve land access for young people, thus enhancing their livelihoods and fostering entrepreneurial growth in the most promising segments of the agricultural value chain.

(Services for Science and Education – United Kingdom, 2022-08-10) Rogito, Jeremiah; Makhanu, Everlyne
Agribusiness offers huge employment potential considering its wider labour absorptive capacity. However, youth involvement in agribusiness in Kakamega County, Kenya is low. The study aimed at assessing the relationship between access to information services and youth involvement in agribusiness value chains. Stratified and simple random sampling was adopted to select 240 respondents. Data collected was analyzed to generate frequencies, percentages and correlation. It was established that there is a strong correlation between access to information and youth involvement in agricultural value chains. Lack of or inadequate access to information services is a key constrain to agricultural productivity in Kakamega county as it affects all aspects of the value chain except consumption. County governments and the Ministry of Agriculture will use these findings to design appropriate agricultural messaging strategies. Policymakers and Donor agencies using these findings will be able to formulate policies that will enhance youth involvement in the Value Chain by knowing what segments of the value chain to focus on youth intervention strategies.
Strategic Management Determinants of Value Addition in the Sea Food Processing Sub-Chain: A Survey of Industrial Fish Processors in Kenya
(ARC journals, 2014-06) Theuri, Fridah Simba; Mwirigi, Fred Mugambi; Namusonge, G.
The purpose of the study was to assess the strategic management determinants of value addition in the sea food processing sub chain. The study adopted a descriptive research design, the study targeted 127 respondents for the study and 93 questionnaires were returned which indicates a 73.22% response rate. To test reliability, Cronbach alpha was used to test the reliability of the instrument. The results were highly reliable and all the items appeared worthy of retention. Questionnaires were administered with the help of data collectors. Data was collected; questionnaires were coded and checked for completeness before data collected was entered in SPSS 20.0 for analysis. The study found out that there was 68.2% of corresponding change in value addition of IFPs in every change in all the four predictor variables jointly. Test of overall significance of all the four variables jointly using ANOVA at 0.05 level of significance and found the model to be significant. Policy and managerial recommendations were made among them; the study recommends that the fisheries management bill of 2014 should be adopted so as to create an enabling marine fishing environment for local fisher men. The study also recommends that the government needs to consider licensing foreign fishing company so as to invest in Kenya and necessary legal framework to enable the government invest and develop the marine sub-sector is needed. On technological advancement, there is need to create fishing ports in Mombasa, Kilifi and Lamu and these ports should be fitted with modern cooling equipment to avoid post harvest losses by building cold chain facilities and value addition.

(MKU Journals, 2012-04) Mwirigi, Fred Mugambi; Theuri, Fridah Simba
The general objective of this study was to identify the challenges faced in the process of adding value in the sea food supply chain along the Kenyan coast, with particular interest on fish, and propose sustainable solutions to these challenges. This study looks closely at the key value chain activities that characterize the sea food industry along the Kenyan coastline with the view of establishing their completeness and efficiency. It further identifies the gaps that exist in the chain and recommends measures that can be implemented to improve the chains. To achieve this objective the researchers identified the value chain activities that characterize the seafood industry in Kenya with specific reference to the Kenyan coastline and analyzed the gaps and challenges that exist in the value chain. The study has gone further to develop recommendations on policy and non-policy mitigation options to the value chain gaps and challenges that have been identified. Information gathered and the recommendations thereof will help to create a more complete and efficient chain and, therefore, optimize the economic as well as social benefits of the seafood industry to the country.
Assessment of profit efficiency of smallholder potato farmers in Nakuru County, Kenya
(Crop Science Society of America, 2024-11-19) Chemjor, Henry; Mose, Jared; Ngeno, Vincent
The importance of potato (Solanum tuberosum L) production to the country's economic growth is quite clear, but little is known about its profitability and determinants. The current potato yields of smallholder farmers are <10 t/ha, against 40 t/ha achievable under optimum utilization of resources and recommended agronomic practices. The objective of the study was to assess the gross margin (GM) of smallholder potato farmers and estimate their profit efficiency level and influencing factors. A cross-sectional research design and multistage sampling technique were used to obtain a sample of 277 respondents for the study. Results indicated an average GM of Ksh 57,438 per ha per season, implying that potato farming is a lucrative enterprise. Despite this, the study further showed that there are profit inefficiencies in its production process. The average profit efficiency recorded was 43.5%, implying that potato farmers can potentially increase their profits up to 56.5%. Profit efficiency was found to increase significantly with access to extension and credit services, education level, non-farm income, and membership in farmer groups, while decreasing significantly with farmer age. Apart from optimizing the use of farm inputs, the profit efficiency of smallholder potato farmers can thus be improved by enhancing farmer education and extension service delivery, formulating favorable credit strategies that will make loan acquisition easier for potato farmers, and encouraging farmers to join farmer groups in order to benefit from economies of scale.
Assessing the determinants of tissue culture banana adoption in western Kenya
(The African Journals Online, 2016-03-17) Wanyama, J. M.; Obare, G. A.; Owuor, G.; Wasilwa, L.
In this study cross-section data was used to analyze the effect of farmers’ demographic, socioeconomic and institutional setting, market access and physical attributes on the probability and intensity of tissue culture banana (TCB) adoption. The study was carried out between July 2011 and November 2011. Both descriptive (mean, variance, promotions) and regression analysis were used in the analysis. A double hurdle regression model was fitted on the data. Using multistage sampling technique, four counties and eight sub-locations were randomly selected. Using random sampling technique, three hundred and thirty farmers were selected from a list of banana households in the selected sub-locations. The adoption level of tissue culture banana (TCB) was about 32%. The results also revealed that the likelihood of TCB adoption was significantly influenced by: availability of TCB planting material, proportion of banana income to the total farm income, per capita household expenditure and the location of the farmer in Kisii County; while those that significantly influenced the intensity of TCB adoption were: occupation of farmers, family size, labour source, farm size, soil fertility, availability/access of TCB plantlets to farmers, distance to banana market, use of manure in planting banana, access to agricultural extension services and index of TCB/non-TCB banana cultivar attributes which were scored by farmers. Compared to West Pokot County, farmers located in Bungoma County are more significantly and likely to adopt TCB technology. Therefore, the results of the study suggest that the probability of adoption and intensity of the use of TCB should be enhanced. This can be done by taking cognizance of these variables in order to meet the priority needs of the smallholder farmers who were the target group. This would lead to alleviating banana shortage in the region for enhanced food security. Subsequently, actors along the banana value chain are encouraged to target the intervention strategies based on the identified farmer, farm and institutional characteristics for enhanced impact on food provision. Opening up more TCB multiplication centres in different regions will make farmers access the TCB technology for enhanced impact on the target population.Keywords: Farmer, Adoption, Tissue culture banana, double-hurdle, model, West Kenya

(Journal of Marketing and Consumer Research, 2016) Chepkwony, Joel Kipkemboi; Lagat, Charles
The study purpose is to determine the effect of E-ordering and E-informing on supply chain performance. The study was informed Innovation Diffusion Theory. Explanatory research design was employed in this study. Targeted population was 244 procurement officers from 112 Kenyan Retail outlets. Multiple regression model findings showed that e-ordering and e-informing had a positive and significant effect on supply chain performance. The study concludes that e-ordering and e-informing which are elements of e-procurement dimensions increases supply chain performance. There is therefore need for firms to make use of e-ordering and e-informing in the procurement process. There is also need to electronically consult references for product/service quality so as to heighten supply chain performance
Characterization of kitchen and municipal organic waste for biogas production: Effect of parameters
(Heliyon PMID, 2023) R, Mrosso; Ac, Mecha; J, Kiplagat
Globally, the production of municipal solid waste is rising annually because of consumerism and the urbanization process. In the past few years, different researchers have explored strategies for generating biogas from various organic wastes. In this study, kitchen waste and municipal solid waste were characterized by several physical-chemical parameters. Ten of these substrates were mono-digested for biogas production in batch reactors where cabbage showed a 96.36 ± 1.73% volatile solid and biogas yield of 800 ± 8.8 mL within 10 days, while cooked rice had an 83.00 ± 1.49% volatile solid, and a biogas yield of 2821 ± 31.03 mL within 28 days. The CN ratio for cabbage and cooked rice waste was 13.9 and 30.9 respectively, whereas their pH values were 6.2 and 7.2. Based on the characterization and biogas yields attained, cooked rice waste could be mono-digested for biogas production and no published work showed a high yield as the current study while the other substrates require co-digestion to improve the biogas yield.
