By enabling localized, on-demand production, AM/3D can revolutionize various sectors, including agriculture, food processing, and rural development. This study explores the current state of implementation of AM, challenges being faced by the industries in implementing AM technologies, and success stories in the nearby countries like South Africa and Botswana. Furthermore, the authors explored the opportunities where AM can be used. In the agricultural sector, the authors delved into specific applications, including the creation of precision agricultural tools, custom-fit prosthetic devices for farm workers, and innovative packaging solutions for perishable goods. Additionally, the study discusses the positive economic implications of AM adoption, including job creation, reduced reliance on imports, and the promotion of sustainable practices. By leveraging AM, 3rd world countries like Zimbabwe can unlock new avenues for growth, improve livelihoods, and enhance their global competitiveness. Furthermore, the study draws up the implementation framework of AM technology in Zimbabwe's agriculture, highlighting the need to involve institutions of higher learning and research to involve all provinces. 2024-01-01T00:00:00Z Gwatidzo, Oscar Tigere, Godfrey Ndiyamba, David https://cris.library.msu.ac.zw//handle/11408/6940 Title: Enhancing Mechanical Engineering Education in Zimbabwe through Identifying Critical Equipment, Facilities, and Maintenance Strategies for Effective Training at Universities Authors: Ndiyamba, David; Murena, Eriyeti; Zendera, Willard; Mafuratidze, Francis; Madzudzo, Erasmus Abstract: Enhancing practical skills training at universities requires the availability, adequacy, relevance, and proper maintenance of critical equipment and facilities. Improper maintenance of workshop facilities hampers effective teaching and the acquisition of skills. In this regard, this paper focuses on investigating the equipment needed for mechanical engineering institutional workshops, its failures, and its maintenance. Mixed methods were used, including a review of work on critical equipment for comprehensive engineering training based on educator and employer perspectives, with online research and physical visits employed to carry out observations. Microsoft Excel and Microsoft Access were used to analyze data and develop a computerized maintenance system to support the maintenance of training equipment and facilities. A priority list of essential facilities and machinery was developed, and maintenance plans were proposed based on a pilot study of two key machine tools, the milling machine and lathe, which were used in the experimental construction of an automated maintenance management system. This study can be utilized to enhance the skills and proficiencies of mechanical engineering graduates, enabling them to be employable and contribute positively to solving social and economic challenges. 2024-01-01T00:00:00Z Ndiyamba, David Murena, Eriyeti Zendera, Willard Mafuratidze, Francis Madzudzo, Erasmus https://cris.library.msu.ac.zw//handle/11408/6938 Title: Renewable energy adoption and integration in South Africa: an overview Authors: Kumba, Hagreaves; Akpan, J.; Twite, B.; Olanrewaju, O. Abstract: The United Nations Sustainable Development Goal (SDG) 7 of ensuring access to affordable, reliable, sustainable, and modern energy for all is of critical importance to the development and growth of South Africa's economy. The ambition in SDG 7 is that by 2030 there should be universal access to affordable, reliable, and modern energy services. Electricity as energy is an essential enabler of economic development that can lift people out of poverty, therefore supporting sustainable development and industrialization. Improved access to energy in South Africa has the potential to alleviate poverty, promote industrialization and economic development. However, challenges with the state-owned energy utility company, Eskom, have resulted in the country experiencing regular power cuts. This article aims to provide a substantial review of the current renewable energy scenario in South Africa considering the faced challenges and their potential solutions for sustainable development. It will also highlight some of the progress on SDG7 integration, strategies, and innovations in support to expedite South Africa progress towards universal energy access. The discussion serves as a guide to further investigate the development of renewable energy projects and the barriers to the implementation. 2023-01-01T00:00:00Z Kumba, Hagreaves Akpan, J. Twite, B.

It begins with an overview of current energy sources and trends, highlighting the disparity between supply and increasing demand. Adverse impacts of reliance on fossil fuels such as environmental degradation, economic volatility, and health hazards underscore the urgent need for a transition. The study then explores the vast potential of renewable energy sources (RES) such as solar, wind, hydrogen, and hydro, emphasizing their feasibility in the Southern African context. The positive impacts of integrating renewables are examined, including reduced greenhouse gas emissions, enhanced energy security, and economic diversification. Through case studies of regional examples, the success and failures of transitioning efforts are analyzed, providing valuable insights into best practices and pitfalls. The study identifies significant challenges in transitioning, particularly in grid-tied and off-grid scenarios, and discusses infrastructural, financial, and regulatory obstacles. The recommendations section outlines strategic steps for achieving a feasible transition, proposing either a full transition or specific percentages of renewable energy integration to meet energy demands. In conclusion, the study emphasizes the critical importance of adopting these strategies for sustainable development and global climate goals, advocating for continuous innovation and localized solutions to maximize the benefits of renewable energy. Key findings are that the environmental and economic effects of fossil fuel usage strain economies by increasing fossil fuel subsidies. RES are abundant in the Southern African region, and some projects have already been successfully implemented, especially in South Africa. Economic growth and technological advancement are some of the benefits of fully transitioning to renewables, but lack of skilled labor, infrastructure, necessary technology, and most importantly, high capital requirements, etc., are some challenges being faced. Hence, the need for regional cooperation, policy frameworks, and infrastructure enhancement, and investment mobilization for an accelerated transition. 2025-01-01T00:00:00Z Charamba, Anesu Nicholas Kumba, Hagreaves Makepa, Denzel Christopher
