Agriculture Risk Financing research chair
Prof Johan van Niekerk, Vice-Dean for Agriculture for the Faculty of Natural and Agricultural Sciences; Prof Liezel Massyn, UFS Business School; Prof Nicolene Barkhuizen, Director of the UFS Business School; and Prof Cobus Oberholster, from the Agriculture Risk Financing research chair.

A newly established multi-stakeholder research chair at the University of the Free State (UFS) Business School will focus on holistic and interdisciplinary research that will create new knowledge, contribute to climate change adaptation and mitigation in the food and agricultural sector.

The Agriculture Risk Financing research chair, led by Prof Cobus Oberholster from the Business School, will also support sector specific policy development and implementation, and steer the societal discourse on climate financing and sustainable agriculture. The chair forms part of the UFS, Agricultural Research Council (ARC), and the Department of Agriculture, Land Reform and Rural Development (DALRRD) research chairs. Prof Oberholster joined the university on 1 February 2025 in this prestigious position which is a collaboration between the Business School and the UFS Department of Agricultural Economics.

Prof Oberholster, who spent a big portion of his corporate career in the banking environment, brings extensive expertise in climate finance, resource mobilisation, and sustainable economic practices. His appointment marks a significant milestone in advancing research at the intersection of finance, sustainability, and agriculture, ensuring that innovative financial solutions contribute to environmental resilience and responsible resource management. Prof Oberholster also gained extensive management experience over the past 15 years regarding the agribusiness environment (non-Bank) in South Africa with a specific focus on value-chain financing.

Focus of research chair

Says Prof Oberholster: “The research chair will strategically focus on the mainstreaming of climate-smart financing solutions within the food and agricultural sector. To achieve this, the research will focus on three strategic and interrelated pillars (Regulatory and policy, Entrepreneurial market exchanges and Digital financial innovations), which aim to provide a governance framework within which innovative financing and market mechanisms can be developed and commercialised.

“The chair will reside at the UFS Business School, but form part of a group of research chairs being hosted within the Faculty of Natural and Agricultural Science. These chairs cover the full food and agricultural value chain, which allow for leveraging the output of the chair within very specific components of the value agrifood value chain.”

The ARC-DALLRD-UFS research chairs were established last year in an effort to address the challenges and impact of climate change in Southern Africa and fall under the umbrella of climate change.

Prof Oberholster, who completed two doctoral degrees focusing on agriculture, agricultural development, and agricultural financing, says he is excited to be part of this joint initiative, and the opportunity to share his business and financing experience. “Climate change, and the corresponding need to find innovative financing solutions, is currently one of the biggest global challenges. It requires an accelerated and responsible approach to research and innovation which, together with the university’s trusted reputation, must be used to build social licence for disruptive technological solutions.”

Contributing to food security

According to Prof Oberholster, both the UFS Business School and the faculty, are ideally suited to find complementary commercial solutions for accessing and mobilising climate finance in South Africa and the wider African continent. The chair, through the UFS Business School, will also focus on capacity building which will be done through selected training and educational interventions, with the aim of addressing existing constraints in mobilising and accessing climate finance.

“The chair will focus on the integration of social, ethical and environmental parameters into climate-financing decisions. By focusing on these key sustainability aspects, access to climate finance will not only contribute to specific development objectives but also significantly contribute to food security,” Prof Oberholster says.

“Climate change, and the corresponding need to find innovative financing solutions, is currently one of the biggest global challenges. As such I’m looking forward to guide the creation of new knowledge in this specialised field, and especially to find complementary commercial solutions for accessing and mobilising climate finance in South Africa and the bigger African continent. What is standing out for me is the level of expertise available within the UFS, and the willingness of academics to work together on grand challenges such as climate finance. This is a winning recipe.”

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.”
