The University of the Free State (UFS) has appointed Prof John Klaasen as Dean: Faculty of Theology and Religion from 1 April 2024. 

Prof Klaasen is Professor of Theology and has served two terms as Head of the Department of Religion and Theology at the University of the Western Cape. He also served as Professor in the Kjell Nordstokke Chair in Community Development at VID Specialized University in Norway and is Adjunct Professor at VID Specialized University. 

“With his vast experience and involvement in research projects – nationally as well as internationally – Prof Klaasen will make a significant contribution to the Faculty of Theology and Religion and the university in general. This will also be valuable in support of the university’s Vision 130, which is an expression of our strategic intent to position the institution towards 2034 when the UFS will be 130 years old,” says Prof Francis Petersen, Vice-Chancellor and Principal of the UFS.

As a practical theologian, the intersection between praxis and theory has occupied Prof Klaasen’s research for the past decade. He has researched and published extensively within theology, community development, and narrative. Aspects such as narrative, embedded knowledge, participation, reconciliation, and the non-rational tradition of knowledge are some of the areas that occupy his research outputs.

He is involved in numerous international research projects, which include a COST project with 17 European institutions, a project on reconciliation processes with institutions in Canada and Nordic countries, an international initiative on community development with various institutions in Europe, and a NORPART initiative with Norway and Malawi.

Community engaged scholarship forms a central part of his research and work at the intersection of religion and social justice. Prof Klaasen is involved in various community development projects, including homes for the aged, lay training, water issues, and lay theological education.

His teaching is situated within a socially just pedagogy, which puts the students at the centre of knowledge production. This innovative way of knowledge production intersects students, teachers, and the lecture room within a dynamic space of contextualisation.

“I am grateful for the opportunity to join such a prestigious institution and will endeavour to contribute to Vision 130 through commitment, innovation, trust, and ethical leadership – which represents the university’s commitment to be recognised by our peers and society as a top-tier university in South Africa, ranked among the best in the world,” says Prof Klaasen.

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.
