Momentous and joyous – these are some of the words used to describe the December 2024 graduations at the University of the Free State (UFS). In celebration of the academic achievements of its students, the UFS hosted graduation ceremonies at the Callie Human Centre on its Bloemfontein Campus from 9 to 10 December 2024.

Prof Anthea Rhoda, acting Vice-Chancellor and Principal of the UFS, encouraged the graduates to always acknowledge and recognise the significance of this achievement as they transition from being UFS students to being UFS graduates.

Undergraduate and postgraduate achievements

At least 2000 undergraduate qualifications and postgraduate qualifications were conferred. As such, there were some standout academic achievements across the sessions. For instance, Itumeleng Pooe received his Advanced Diploma in Theology cum laude, making him the only graduate in the Faculty of Theology and Religion to receive his qualification with distinction during these graduations. In addition, Dr Bobuin Jr Valey Gemandze Oben – at just 28 years old – was the youngest PhD graduate from the Faculty of Law at the graduation ceremony, which took place on the morning of 9 December 2024.

Conferring Honorary Doctorates

Some highlights from these graduations were the recipients of honorary doctorates, as well as the keynote speakers. The Faculty of Economic and Management Sciences (EMS) at the UFS conferred an honorary degree on Prof Murray Leibbrandt, Research Chair in Poverty and Inequality Research in the Southern Africa Labour and Development Research Unit (SALDRU) at the University of Cape Town (UCT). In addition, the Faculty of The Humanities at the UFS conferred an honorary degree on HE Bineta Diop, Special Envoy of the Chairperson of the African Union Commission on Women, Peace, and Security.

On the final day of the graduations, graduates within the Faculty of Health Sciences at the UFS were addressed by Lieutenant Colonel Dr Rifa Tshivhase, Head of the Department of Surgery at 3 Military Hospital in Bloemfontein. In her address, Lieutenant Colonel Dr Tshivhase encouraged and challenged the graduates to actively seek out good in the world.

As the December 2024 graduations concluded, several of the graduates within the Faculty of Health Sciences indicated that the most memorable moments in the session were the cheers and applause they received as they walked across the stage.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
