Research Chairs 2024
Prof Paul Oberholster, Dean: NAS; Dr Glen Taylor, Senior Director for the Directorate Research Development (DRD); Prof Vasu Reddy, Deputy Vice-Chancellor, Research and Internationalisation; and Prof Johan van Niekerk, Vice-Dean for Agriculture in the Faculty of Natural and Agricultural Sciences (NAS); are excited for the new ARC-DALLRD-UFS research chairs.

In a concerted effort to address the challenges and impact of climate change in Southern Africa, the University of the Free State (UFS) together with the Agricultural Research Council (ARC) and the Department of Agriculture, Land Reform and Rural Development (DALRRD) established four new research chairs within the Faculty of Natural and Agricultural Sciences (NAS).

The ARC-DALLRD-UFS research chairs, namely Climate Change and Agriculture, Innovative Agro-processing for Climate-smart Food System, Agriculture Risk Financing and Sustainable Livestock Production, falls under the umbrella of climate change and are part of the established centre of excellence of the ARC and DALRRD on Climate Smart Agriculture.

They will form part of two centres of excellence that the university is also in the process of establishing. The framework for these Agriculture Research Centres of Excellence involves several key components aimed at fostering innovation, collaboration, and impactful research in agriculture. In this case it is Climate Smart Agriculture, enabling them to play a pivotal role in advancing agriculture, enhancing productivity, sustainability, and resilience in the face of global challenges related to climate change.

Prof Johan van Niekerk, Vice-Dean for Agriculture for NAS, and Prof Sonja Venter, from the ARC, are the coordinators for the ARC-UFS-consortium. Joel Mamabolo from the DALRRD is the department’s representative and DALRRD manager in the consortium.

The purpose of the research chairs, he explains, is to conduct high-level research with an aspect of community impact as envisaged in the university’s vision 130. This is the UFS and NAS’s first steps towards creating industry chairs with negotiations between the UFS and the ARC-DALRRD currently taking place for further expansion of the chairs.

Improve research and food security

“The UFS has a long-standing relationship with the ARC and the parties came together to work together to improve research and food security in South Africa and Sub-Saharan Africa. The best way to do this, was by creating research chairs. The ARC saw the university’s expertise in agriculture which also contributed to the ARC establishing the chairs. Our expertise is of such a nature that it does not only influence the sector, but also makes a lasting difference,” says Prof Van Niekerk.

According to him, the ARC and the UFS will collectively manage the research chairs by appointing co-chair principal scientists for each of the chairs in order for the chairs to work together and share resources and expertise. The ARC-DALLRD-UFS research chairs will also work closely together within multidisciplinary research teams and complement each other and in doing so, create a value chain within the agriculture sector.

It will integrate various disciplines including agronomy, genetics, soil science, ecology, pathology economics, socioeconomics horticulture, animal sciences, food sciences and engineering to mention a few. This multidisciplinary approach will foster comprehensive research solutions and innovation at the intersection of different fields and will aim to contribute to sustainable food systems for the future.

The first two chairs; Climate Change and Agriculture, headed by Prof Linus Franke, Head of the UFS Department of Soil, Crop, and Climate Sciences, and the Innovative Agro-processing for Climate-smart Food System, which will be under Dr Alba du Toit, Senior Lecturer in the Department of Sustainable Food Systems and Development, officially started on 1 July 2024, while the remaining two chairs will begin operating in December. The ARC will soon confirm the co-leaders of the various chairs.

The Agriculture Risk Financing research chair will be shared between the Department of Agricultural Economics, within NAS, and the UFS Business School. The Sustainable Livestock Production chair will fall within Prof Frikkie Neser’s Department of Animal Science. To add more credibility, experience and expertise to the ARC-DALLRD-UFS research chairs, Prof Maryke Labuschagne, who is leading the NRF SARChI Chair in Diseases and Quality of Field Crops, has been appointed as mentor.

Prof Vasu Reddy, Deputy Vice-Chancellor, Research and Internationalisation, says: “These chairs mark an exciting opportunity to deepen our understanding of climate change aligned to our expertise in agriculture. The chairs offer us the opportunity to honour and support the leaders who will contribute in powerful ways to the vibrant intellectual life of the faculty, as well as the university, the ARC and DALRRD.

“The chairs also honour the donor whose financial support makes this form of recognition possible. At the UFS we are committed to engaging in global challenges but with a deliberate local focus, energy and drive. I am especially excited that these chairs demonstrate a commitment to the UFS focus on partnerships with industry, communities, the state and other academic and research institutions both nationally and around the world.”

Grateful for the ARC relationship

Through these chairs more collaborators and partners from other universities in the country and globally will be included in the partnership with the aim to bring together internationally renowned scientific experts that will collectively focus to address global challenges and enhance the development of more scientific capacity for the country.

The university, Prof Van Niekerk continues, is grateful for the cooperation and relationship with the ARC and its President and CEO, Dr Litha Magingxa and the executive management team, as well as the DALRRD DG, Mooketsa Ramasodi and the DDG for Agricultural Production, Biosecurity and Natural Resources Management, Dipepeneneng Serage for creating an environment within which the Universities and ARC can collectively contribute towards developing solutions with the DALRRD for key agricultural challenges of the country.

He expressed his gratitude to the Directorate Research Development (DRD) under the leadership of Dr Glen Taylor, for not only their support, but for bringing the parties together and negotiating with the ARC on their behalf. In this regard he wishes to thank Dr Petronella Chaminuka from the ARC as the acting Executive Manager: Research support and coordination for her support, guidance and leadership during the process.

Prof Van Niekerk also thanked Profs Francis Petersen, UFS Vice-Chancellor and Principal, Reddy, and Paul Oberholster, Dean of the Faculty of NAS, for creating the environment and rendering immense support for this programme from the UFS.

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
