The issue of seasons that make it difficult to grow crops is disregarded or completely ignored in such a scenario. Maximum yield is realized in this instance as a result of controlled temperature, humidity, soil moisture to mention but a few parameters that are kept under check so that crops have optimal conditions for growth at any one given time. To further buttress the issue of crop yield it is critical to consider pests and diseases in the equation. Mitigation efforts to monitor and control pests and diseases assists in coming up with a quality crop that translate into a bumper harvest. In order to achieve this Internet of Things and Embedded systems together with Machine Learning techniques are used. Sensor readings of these environmental parameters together with crop image status are used to train a model that help identify patterns followed by pests and diseases thus assisting in decision-making purposes to curtail pests and diseases spread. Once a disease or pest is identified through a camera as a result of image processing, an actuator connected to a tank with chemical spray go high thus spraying all tomato plants in the greenhouse affected by red spider mite to correct the anomaly. The greenhouse is highly automated although minimal human effort cannot be overlooked. Sensor readings and crop images are stored in the cloud as big data. With this information, farmers can plan ahead, gather required chemicals and inputs in preparation for spraying pests and diseases once they surface. Stakeholders can view status of the green house via a smart phone, a laptop or a desktop so long there is a reliable internet connection.

It uses a GAD approach. 4. chapter examines the impediments that derail the intensive uptake of eLearning programmes in a particular higher education institution. The study adopted an inductive research paradigm that followed a qualitative research strategy. Data were collected by means of one-on-one in-depth interviews from selected faculty members at a nominated institution of higher learning. 5. chapter investigated the role of KMS in enhancing the export performance of firms operating within the manufacturing sector in Zimbabwe. The study used a...

However, their use within the manufacturing sector in developing countries remains inconsistent. This article investigated the role of KMS in enhancing the export performance of firms operating within the manufacturing sector in Zimbabwe. The study used a quantitative approach in which a survey questionnaire was distributed to 555 managers drawn from 185 manufacturing firms based in Harare. Data analyses involved the use of descriptive statistics, Spearman correlations and regression analysis. The results of the study showed that combined IT/social driven KMS exerted the greatest impact on export performance. The availability of both information technology centered and social centered KMS influences export performance by improving the firm’s export strategy, export commitment, ex...

May honour, praise, glory and worship be given to Him forever and ever Amen. • Secondly, I want to thank my wife, Shamiso Ngoni Tarambiwa, my children, Dorothy, Andrew, Ropafadzo and Tinotenda for their encouragement and unwavering support during the challenging times of data collection and compilation of the thesis. When economic situations were pulling in another direction and I was wasted and almost giving up, they encouraged me and helped me to regain my confidence until by God's grace the work was completed. • Thirdly, I want to give special thanks to my promoter, Prof. Chengedzai Mafini for being both a promoter, spiritual guide and counsellor during the entire study period. He provided me with the necessary research skills (i.e. both qualitative and quantitative), which I lacked and provided the technical guidance as and when it was needed. I want to thank him for the academic and social support guiding me through to all seminars, venues, conferences and whichever knowledge I was lacking. Indeed, my appreciation can never be fully expressed in written form. May the Lord continue to bless you and grant you all your prayer requests. • Fourthly, my co-promoter, Prof. Andrea Garnett for the technical guidance especially adding to Prof. Mafini on academic writing and consistency and coherence in thesis compilation. She was always ready to attend to the chapters as I was sending them to her and responding on time. May the Lord continue to bless you. • Lastly, I would like to give special mention of all VUT staff, namely, the security, academic staff, library staff and higher degrees staff for always being there when I needed their support in applications, registration, directions and access to resources. Great appreciation also goes to the Zimbabwean Ministry of Small and Medium Enterprises, the Small and Medium Enterprises Association of Zimbabwe (SMEAZ) for their support in providing authority for conducting data collection. I also want to express my appreciation for the Government of the Republic of South Africa and VUT management for the financial support provided for conducting the research. Thank you all and may God bless each one of you as we await the soon appearing of our Lord

Business and government processes are changing with the use of the internet, mobile devices, internet of things, blockchain, machine learning, artificial intelligence and many other new technologies. In this book, it is aimed to focus the use of technology, new trends in business life and government covering the studies in all sub-areas of Information Systems, Knowledge Management, eBusiness, eCommerce, eMarketing, mCommerce, eGovernment, ePublic Services, eGovernance etc. The book consists of 7 chapters. Book chapter authors are reputable scientists from different countries of the world. The first chapter is a critical review and a case study in e-Business, with special attention to the digital currencies resource and its possibilities. The second chapter attempts to incorporate the Unified Theory of Acceptance and Use of Technology (UTAUT) model with perceived risk theory (security risk and privacy risk) to explore its impact towards the intention to use m-government services. The third chapter aims to assess the level of gender inclusivity in the municipal e-procurement processes in the City of Johannesburg as a case study. The fourth chapter examines the impediments that derail the intensive uptake of eLearning programmes in a particular higher education institution. The fifth chapter investigated the role of Knowledge Management Systems (KMS) in enhancing the export performance of firms operating within the manufacturing sector in Zimbabwe. In the sixth chapter, a survey was undertaken on 131 small and medium-sized enterprises (SMEs) from Pelagonija region in order to determine the current level of SME digitalization within the region. It is aimed to compare with European Union (EU) average and to make conclusions on the impact of the SME digitalization to region gross domestic product (GDP) growth as well as revenues collection. The last chapter's purpose was to develop a measuring and modelling framework/instrument of Internet banking service quality (IBSQ) for the South African banking sector.
