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.

Carbon dioxide makes for more aromatic decaffeinated coffee

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way.

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night.

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants.

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
