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.”

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
