The University of the Free State (UFS) has welcomed a cohort of international students as part of the Mobility 4 Agricultural International Networks Supporting Thematic Resilience and Enhancing Adaptation and Mitigation (MAINSTREAM) project, a significant European Union-funded initiative aimed at boosting agricultural education and research across the African continent.

A group of postgraduate students from Togo and Ethiopia have recently joined the University of the Free State as part of the MAINSTREAM project. “Two doctoral students from Togo – Ame Houngo and Fanny Sibabi – are based in the Department of Sustainable Food Systems and Development and will be supervised by Dr Alba du Toit and Prof Maryke Labuschagne,” says Prof Corli Witthuhn from the Department of Sustainable Food Systems and Development at the UFS, who serves as the coordinator of the MAINSTREAM project. Master’s student Prudence Bilabina, also from Togo, is hosted by the Department of Agricultural Economics under the supervision of Prof Henry Jordaan.

From Ethiopia, doctoral student Debela Bedada and master’s student Gemedo Shengu are both pursuing their research in the Department of Agricultural Economics, supervised by Prof Nicky Matthews and Dr Janus Henning respectively.

A Ugandan student will soon join them on 22 April for a three-month traineeship. “He is an undergraduate Agriculture student who will register for a service-learning module at the UFS and spend the three months working on a farm,” explains Prof Witthuhn. The student hails from the Mountains of the Moon University in Uganda.

By June 2025, the university anticipates the arrival of four more students from Uganda – three at master’s level and one traineeship participant – bringing the total number of MAINSTREAM students hosted by UFS this year to ten.

 

Building a climate-resilient future through agricultural education

The MAINSTREAM project aims to foster education and skills improvement in agricultural knowledge systems, with a strong focus on climate change resilience. According to Prof Witthuhn, the project “strives to influence the common agenda for addressing education and skills improvement … targeting transformations with the tertiary agricultural education community, policy, and industry actors”.

An important aspect of the initiative is its emphasis on inclusion, particularly regarding African women who remain underrepresented in higher education agricultural programmes. “Mobility schemes will also be used to break cross-African gendered perceptions of agriculture … and to further provide for a gender-sensitive learning environment and institutional culture,” Prof Witthuhn notes.

The UFS’ participation forms part of a larger network of partner institutions across Africa and Europe, including Arsi University (Ethiopia), the University of Kara (Togo), the Mountains of the Moon University (Uganda), Jaramogi Oginga Odinga University of Science and Technology (JOOUST, Kenya), the University of Sine Saloum El Hadji Ibrahima Niasse (USSEIN, Senegal), and the Weihenstephan-Triesdorf University of Applied Science (Germany).

 

Strengthening research, networks, and collaboration at the UFS

This four-year project, running from 2024 to 2027, will host two cohorts of students. “We are a partner in the project that will run over four years … one of the UFS master’s students, Rinus Behrens from the Department of Sustainable Food Systems and Development, is currently spending four months at JOOUST in Kenya as part of the programme,” adds Prof Witthuhn.

The presence of these students at the UFS marks a pivotal moment for both the institution and its international counterparts. “For the institution, it creates the opportunity for new networks, new research opportunities, internationalisation of our research endeavour, and increased research outputs,” she says.

During their stay, master’s and doctoral students will engage in academic research aligned with their fields of study, while traineeship students will gain hands-on agricultural experience on farms in the Bloemfontein area.

Bedada says the programme is already making a meaningful impact on his academic journey. “I am analysing the impact of agricultural mechanisation on food security and production. It is a big opportunity, because it gives me a chance to expand my knowledge and skills, and to develop my research work to international level.”

Similarly, Houngo says the experience so far has been enriching. “I have already learned a lot, and I hope to replicate the experience in my hometown,” he shares.

Behind the scenes, UFS staff and departments are instrumental in ensuring the programme’s success. “They provide host departments, academic leadership, and supervision to the six students,” says Prof Witthuhn, emphasising the collaborative effort required to support this international initiative.

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.
