e-Agriculture promising practice UshuariKilimo information system web and mobile phones for extension services in Tanzania
(FAO, 2018-05) Sanga, C.
‘UshauriKilimo’ is a Swahili word from ‘Ushauri’ and ‘Kilimo’ which means ‘advisory’ and ‘agriculture’ respectively. ‘UshauriKilimo’ is a system for agricultural advisory services. It is an agro advisory and extension service system that allows any actor in the agricultural sector to ask for advisory services to an agriculture extension officer using either the web or a mobile phone. The mobile and web based advisory information system for farmers was developed in collaboration with the Kilosa Community Radio, using participatory action research to ensure the improved extension services would correspond to the needs of the end users. The Web based Farmers Advisory Information System (MFAIS) and Mobile based Farmers Advisory Information Systems (WFAIS) were released for public use in January 2015, after an awareness raising campaign conducted in Kilosa District of Tanzania.
Human sensor web crowd sourcing security incidents management in Tanzania context
(Scientific Research Publishing, 2018) Mshangi, M.; Nfuka, E. N.; Sanga, C.
Security incidents affecting information systems in cyberspace keep on rising. Researchers have raised interest in finding out how to manage security incidents. Various solutions proposed do not effectively address the problematic situation of security incidents. The study proposes a human sensor web Crowd sourcing platform for reporting, searching, querying, analyzing, visualizing and responding to security incidents as they arise in real time. Human sensor web Crowd sourcing security incidents is an innovative approach for addressing security incidents affecting information systems in cyberspace. It employs outsourcing collaborative efforts initiatives outside the boundaries of the given organization in solving a problematic situation such as how to improve the security of information systems. It was managed by soft systems methodology. Moreover, security maturity level assessment was carried out to determine security requirements for managing security incidents using ISO/IEC 21827: Systems security engineering capability maturity model with a rating scale of 0 - 5. It employed descriptive statistics and non-parametric statistical method to determine the significance of each variable based on a research problem. It used Chi-Square Goodness of Fit Test ( X 2) to determine the statistical significance of result findings. The findings revealed that security controls and security measures are implemented in ad-hoc. For managing security incidents, organizations should use human sensor web Crowd sourcing platform. The study contributes to knowledge base management learning integration: practical implementation of Crowd sourcing in information systems security.
New technologies for disseminating and communicating agriculture knowledge and information:challenges for agricultural research institutes in Tanzania
(2015) Barakabitze, A. A.; Kitindi, E. J.; Ssnga, C.; Shabani, A.; Kibirige, G; Sanga, C.; Philipo, J.; Kibirige, C.
This paper explores how a wide range of Information and Communication Technologies (ICTs) available in Agricultural Research Institutes (ARIs) if used effectively by agriculture researchers can improve agriculture productivity in Tanzania. A structured questionnaire and telephonic interviews were used to collect data from a randomly selected sample of 64 respondents made up of agricultural researchers, agriculture managers and other agricultural stakeholders in the selected institutes. Data were analyzed using statistical tools. The results indicate that ICTs tools are available in ARIs for the day to day research activities. However, utilization of agriculture journals is very limited due to unreliability and poor connectivity of the Internet and frequent power cuts. Results also show that the uses of specialized ICT devices have not taken a great recognition in agriculture activities which is attributed by low investment of ICTs that can be used for teaching and learning modern agriculture productivity techniques in institutes under this study. Among the challenges hindering the use of ICTs in ARIs includes: inadequate computers and the supporting technological infrastructure, lack of electricity needed to operate computers, unreliable Internet connectivity and lack of systematic ICTs investment; low coordination of agriculture stakeholders due to institutional diversity and department fragmentation. This study recommends that the Government of Tanzania (GoT) should formulate and implement ICT for Agriculture (ICT4A) projects based on a researched conceptual framework related to ICT4A use and Information and Communication Management (ICM) in ARIs in Tanzania.
New technologies for teaching and learning: Challenges for higher learning institutions in developing countries
(International Journal of Education and Development using Information and Communication Technology (IJEDICT), 2007) Sife, Alfred S.; Lwoga, Edda Tandi; Sanga, C.
The application of Information and Communication Technologies (ICTs) is already changing the organization and delivery of higher education. The pedagogical and socio-economic forces that have driven the higher learning institutions to adopt and incorporate ICTs in teaching and learning include greater information access; greater communication; synchronous and asynchronous learning; increased cooperation and collaboration, cost-effectiveness and pedagogical improvement. However, ICTs have not permeated to a great extent in many higher learning institutions in most developing countries due to many socio-economic and technological circumstances. This paper discusses new learning and training technologies considering their pedagogical, cost and technical implications. It also discusses challenges for integrating these technologies in higher learning institutions with examples from Tanzania, and giving best practice approaches for addressing each of the challenges.
On the development of climate data visualization tool for interpretation of empirical results from climate model: Does it add value to different stakeholders?
(2013) Sanga, C.; Sumari, N.; Tumbo, S. D.
In time of climate change there is a lot of interest in communicating detailed information and knowledge pertaining to climate to different stakeholders. In order to aid informed decision making related to changing climate and weather variability there is need for data visualization tool. Data visualization tool plays a great role in interpreting bulk climate information produced or collected from different districts, regions and nations at large. In Tanzania, online real-time data visualization tool can help to bridge the gap in the current system whereby climate information is disseminated using television, radio as well as face-to face. These methods have many problems, one being difficulty for end user to aggregate the disseminated climate information over long period of time. This paper seeks to present a work toward developing of a tool for such purpose. The work was done by Database for Crop Models Simulation team from Tanzania with consultation of team members from Kenya, Uganda and Ethiopia. It is anticipated that the tool will enhance efficiency and effectiveness in dissemination and communication of climate information and knowledge to all actors who need it. Furthermore, the results from this study will simulate the debate about climate data visualization in this era
The rapid growth of cybercrimes affecting information systems in the global: is this a myth or reality in Tanzania?
(2014) Nfuka, E. N.; Sanga, C.; Mshangi, M.
The main objective of this study was to determine whether the rapid growth of cybercrimes affecting information systems in the global: is a myth or reality in Tanzania. The study was undertaken using a mixed research methods. The research findings reveal that 12.8 % of users are victims of cybercrimes due to visiting unhealthy websites in cyberspace, more than 90.89% of users have been denied access to torrents/p2p applications (with malicious codes); and more than 63.29% of e-mails received by users are spam. It has been noted that Internet users has risen to 5.63 million users in 2012 out of 46.9 million of population in Tanzania; and is increasing at the rate of 416.98% per year thus expectation of 7.34 million users of Internet by December 2015. The increase in the number of Internet users has direct implication to the increase in cybercrimes affecting information systems. The Government of Tanzania has declared that “about 320 people were apprehended between July and December 2011of which over 1bn/- , Euro 8,897 and USD 551,777 reported to have been stolen through cyber”. The study concluded that there is a need for a holistic approach in addressing cybercrimes in a developing country like Tanzania.
Silent adoption of bring-your-own-device in Tanzania higher learning institutions - adoption policies
(IST-Africa Institute and IIMC, 2020) Magesa, M.; Sanga, C.
Tanzania Higher Learning institutions (HLIs) have not fully deployed the ICT infrastructure to facilitate smooth performance of their business functions. They have inadequate computers, insufficient network infrastructure, low bandwidth; their computers are ageing and have limited ICT investment. The research examined usage of employees’ personal ICT devices for performing office work and the policies, guidelines and practices that can be implemented by HLIs while adopting usage of employees’ personal devices in the work environment. As an interpretive research, data were collected through interviews and observations during the survey at HLI, Sokoine University of Agriculture (SUA). Results confirmed inadequate computers, low bandwidth at HLIs and revealed usage of employees’ personal ICT devices for office work and for communicating issues related to employers’ work. Further, HLIs are not concerned if employees use their ICT devices for office work. It is like HLIs have silently adopted the Bring Your Own Device (BYOD) concept and thus allowed employees to use personal devices to perform office work. The BYOD phenomenon helps to improve the availability of ICT devices at the institution while improving communications and work efficiency and productivity. The research has explored the BYOD concept in Tanzania HLIs and contributed by proposing policies and procedures that can guide in its adoption. Due to its potential benefits, the study recommends HLIs explore how best they can adopt and practise the concept. Further research can explore on the organizational and user characteristics that can facilitate adoption of BYOD.
Stakeholders’ Analysis using Value Chain Analysis: AHP in action
(2013-06) Sanga, C.; Tumbo, S. D.; Mlozi, M. R. S.; Kilima, F.
Choosing stakeholders to be involved in an agricultural value chain research is a complex problem. Many researchers have used different qualitative and quantitative methods but few have tried the multi-criteria decision making algorithm which has ability to combine both methods. The approach used in this research is of great importance to those researchers who are involved in any research studying optimization of evaluation processes in different agricultural value chains. In addition, it can be used to enhance decision making in any phase of research requiring the ranking of evaluation criteria in order to make an informed decision.
Unlocking the potential of the mobile phones by University undergraduate students: A case of Sokoine University of Agriculture
(International Journal of Computing and ICT Research, 2016) Mlozi, M. R. S.; Mussa, M.; Mapunda, K. M.; Kalungwizi, V. J.; Mwakapina, W. J.; Tumbo, S. D.; Sanga, C.
Literature show that use of mobile phones is omnipresent and pervasive in developing countries, especially among the youth. This study was carried out to assess the academic benefits of owning and using mobile phone among the undergraduate students at Sokoine University of Agriculture in Tanzania. Specifically, the study assessed the type of people students communicate to, preferred people and preferred period of the day and also the type of information that is communicated, and when mobile phones are inactivated. Students were randomly sampled from all departments. The study involved semi-structured questionnaires, and 302 undergraduate students who were randomly sampled from various degree programmes participated. The study found that most students prefer to communicate to their mothers and most of the communications are done from late evenings. Family issues were mostly communicated on mobiles phones. Further, the study found little use of mobile phones in academic issues. The study recommends that the University should educate newly enrolled students on proper use of mobile phones, with the view of using mobile phones in academic-related issues.
