JOURNAL OF AGRICULTURE, SCIENCE AND TECHNOLOGY https://ojs.jkuat.ac.ke/index.php/JAGST <p>The Journal of Agriculture, Science, and Technology (JAGST) is a peer-refereed bi-monthly publication first produced in 1997. It features research articles in Agriculture, Biotechnology, Forestry, Human and Veterinary Medicine, Engineering, Architecture, Information Technology, and Physical and Social Sciences. It also carries current scientific reports and, occasionally, reviews of publications with a scientific orientation. <br />The journal serves as an important tool in the mandate of the University’s Research, Production and Extension (RPE) Division to facilitate dissemination of research findings. <br />The goal of the Journal is to:</p> <ul> <li>Provide a forum for the University staff and students, and researchers from the region and other parts of the world to participate in the discovery, transmission, <br />preservation and enhancement of knowledge in various disciplinary areas.</li> <li>Contribute towards the University’s goal of integrating teaching and research for effective application and preservation of knowledge and skills.</li> <li>Provide a platform for sound academic discourse among researchers.</li> </ul> <p>To view issues that were published in the past years i.e. before 2010 click this link :<a href="https://www.ajol.info/index.php/jagst/issue/archive">Previous JAGST issues before 2010</a></p> Jomo Kenyatta University of Agriculture and Technology en-US JOURNAL OF AGRICULTURE, SCIENCE AND TECHNOLOGY 1561-7645 Effect of community participation on performance of major dam projects in Kenya https://ojs.jkuat.ac.ke/index.php/JAGST/article/view/727 <p>Globally, major dam projects are intended to offer significant benefits to the local communities where they are constructed. Evaluations over the years have shown that in the development of major dam projects, it is essential to consider potential social and environmental impacts, such as displacement of communities, alteration of ecosystems, and potential conflicts over water resources. The aim of this study was to establish the effect of community participation on the performance of major dam projects in Kenya. Using a sample size of 221 respondents comprising officials from government ministries and statutory bodies, water service providers, consultant engineers, representatives from donor agencies, and persons living around ongoing dam projects, the study employed questionnaires to collect primary data. Descriptive statistics were used to summarise data through frequency, percentage, mean, and standard deviation, while inferential statistics were computed to determine relationships between the variables. From the descriptive statistics, there was an equal split between those who agreed and those who did not agree that local community members were involved in major dam construction projects. From interviews, on the other hand, most respondents argued that there was no inclusivity and informed consent in project needs assessment, project negotiations, and compensation agreements since the local political leaders hijacked the process for their own selfish ends. The study showed that community participation has a significant positive influence on the performance of major dam projects in Kenya and concluded that the inclusion of objective key stakeholders and representatives of local community members in all phases of dam construction projects could significantly enhance the performance of the projects in the country. The study thus recommends that objective key stakeholders and representatives of the local community be allowed to participate in all phases of dam construction projects so as to enable locals to collectively own and appreciate the social-economic values of dam projects in their locality.</p> Vincent Oguye Monyenye Lango Benard Miroga Julius Cheruiyot Charles K.

Repetitive tasks involving manual lifting or carrying are associated with work-related musculoskeletal disorders. This cross-sectional descriptive study aimed to profile ergonomic hazards, assess health effects among employees, and identify existing control measures implemented in the food and beverage industries in Nairobi County. The study was conducted among a population of 1821 workers in five selected facilities from October 2022 to January 2023. A systematic random sampling technique, following the Yamane (1967:886) statistical method as cited in Leon Mystica (<a href="#Leon">2020</a>), was employed to obtain a representative sample of 328 voluntary participants. Primary data was collected through self-administered structured questionnaires, observations, and taking measurements in the facilities. The study confirmed the literature's theory that most activities performed by employees in the sector are manual, repetitive, and physically demanding, primarily in the manufacturing (56.0%) and warehousing (24.0%) departments. The most prevalent factors contributing to ergonomic hazards and MSDs include excessive force exertion during manual handling, the adoption of awkward body postures, prolonged periods of static positions, and exposure to vibrations. The health effects of ergonomic hazards are further aggravated by the manual handling of heavy material loads and the mismatch between job requirements and employees' physical capabilities. The high occurrence of pain or discomfort among workers is significantly influenced by the poor posture they adopt when performing tasks. Despite a satisfactory combination of control measures implemented in the selected workplaces, their prioritization does not align with the risk control hierarchy described in existing literature. The majority of implemented control measures in the sector are administrative, and there is a lack of adherence and consistency in enforcing safety regulations regarding the maximum load limits for manual lifting.</p> Francis Ayaga Charles Mburu Benson Karanja Copyright (c) 2024 Ayaga Odiwuor Francis, Mburu Charles, Karanja Benson 2024-04-02 2024-04-02 23 1(1) 1 11 10.4314/jagst.v24i1.1
