Famelab
Abdullahi Jamiu, who is working on his master's degree in Microbiology, was adjudicated as the FameLab winner at the Central Regional Heat and will represent the region at the national semi-finals.

Abdullahi Jamiu, who is working on his master's degree in Microbiology in the Department of Microbiology and Biochemistry at the University of the Free State (UFS), was recently announced as the FameLab winner at the Central Regional Heat and will represent the region at the national semi-finals.

Abdullahi, who plans on pursuing a doctoral degree after his master’s, says he wants to establish himself as an academic in microbiology.

Making science simple
He says he decided to participate in the FameLab competition because he is very passionate about communicating science. “Science communication affords me the opportunity to not only take my research outside of the lab space, but also to communicate it to the lay audience. Moreover, science is often perceived by the general public as difficult and unfathomable. As such, science communication programmes promote the simplification and better understanding of scientific knowledge in the community,” he says.

FameLab is coordinated by the South African Agency for Science and Technology Advancement, the British Council, and Jive Media Africa.

According to Abdullahi, the experience was mind-blowing. “It gave me the opportunity to compress my 200-page master's thesis into a three-minute talk in a way I had never thought was possible. Having to present virtually and adjust to the ‘new normal’ was quite challenging,” he adds.

“The overall experience was enlightening and engaging, and at the same time entertaining,” says Abdullahi.

Impressing the judges with his charisma, engagement with the audience, and use of props, Abdullahi’s presentation focused on how the exploration and exploitation of a ‘combination therapy’ approach to drug discovery could help to effectively combat fungal infections, which are the common comorbidities in immune-compromised individuals, including those living with HIV, cancer, and COVID-19.

Revealing an enigma
His fascination with microbiology started at a young age. “How very tiny, microscopic creatures, invisible to the unaided eye, are able to infect and sometimes kill both healthy and immune-compromised individuals, was an enigma to me as a little boy. My desire to unravel this mystery triggered my interest in microbiology, and the more I learn, the more enthusiastic I become to broaden my horizon in this challenging yet exciting field of study,” he says.

Abdullahi would like to one day make a difference by conducting relevant research aimed at contributing to finding lasting solutions to the lingering menace posed by pathogenic microbes. “Moreover, I am very passionate about facilitating the transfer of scientific knowledge to the next generation,” Abdullahi concludes.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
