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.”

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
