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.”

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
