The University of the Free State (UFS) welcomes Prof Jesse Lutabingwa, a visiting Fellow from the Appalachian State University (AppState) in the United States. Prof Lutabingwa arrives under the prestigious Carnegie African Diaspora Fellowship Programme (CADFP), bringing a wealth of experience to support the university's ‘third-income aspirations.’

Prof Lutabingwa’s long-standing connection with the UFS began in 2009 when he played a pivotal role in establishing a collaborative partnership between the two institutions. At the time, he was serving as Associate Vice-Chancellor for International Education and Development at AppState. Now, he returns not as an administrator, but as a faculty member eager to share his expertise and deepen this valuable connection.

"I have always wanted to participate in CADFP to give back to the African continent," Prof Lutabingwa explains. "This fellowship allows me to engage with the UFS community on different issues and contribute to the professional and individual growth of faculty, staff, and students, ultimately serving our communities better."

Empowering through grant writing

A key aspect of Prof Lutabingwa’s fellowship is a series of grant-writing workshops designed to empower UFS faculty, researchers, and postgraduate students, particularly on the Qwaqwa Campus.

"Many find the idea of proposing research grants daunting," Prof Lutabingwa says. "My goal is to elucidate the process. With more than 33 years of experience and more than 65% success rate, I am here to share the knowledge I have gained as a grant writer and reviewer."

These workshops will equip participants with the skills and strategies needed to craft compelling proposals, significantly increasing their chances of securing funding. Access to grants is crucial, Prof Lutabingwa emphasises, as it allows researchers to pursue innovative work that benefits society while offering valuable training opportunities for students.

Collaboration for research impact

Prof Lutabingwa’s contributions extend beyond workshops. He will collaborate with Dr Grey Magaiza, Director of the Centre for Gender and Africa Studies, and other faculty members on co-authoring two research articles. This collaboration aims to strengthen the UFS' research profile and contribute to a more impactful research landscape.

Dr Magaiza highlights the significance of Prof Lutabingwa’s visit: "Jesse is at the heart of the UFS-AppState partnership. Now, as a Carnegie Africa Diaspora fellow, he can engage with us in a new way, pouring his expertise back into this space. His grant-writing workshops and collaborative research efforts will be instrumental in achieving our third-stream aspirations."

Excited about the future

The fellow’s enthusiasm for this fellowship is noticeable when he speaks and engages with colleagues on campus. "Words cannot express my excitement," he shares. "I am grateful for this opportunity to collaborate, engage in research, and connect with various individuals on campus."

The UFS community warmly welcomes Prof Lutabingwa and anticipates a fruitful fellowship that will empower faculty, strengthen research, and propel the UFS – particularly the Qwaqwa Campus – towards achieving its third-income aspirations.

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.
