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.”

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
