PhD candidates at the 2025 National 3MT Competition, hosted at the University of the Free State.

The University of the Free State Centre for Graduate Support (CGS) hosted the 2025 National Three-Minute Thesis (3MT) Competition on 24 October in the Albert Wessels Auditorium, bringing together some of South Africa’s brightest PhD minds under one roof. The annual event, which has become a highlight on the national academic calendar, challenges doctoral candidates from universities across the country to present their complex research in just three minutes, using language accessible to a non-specialist audience. 

This year’s competition drew impressive presentations from top scholars representing various disciplines – from health sciences and agriculture to humanities – all showcasing the depth and diversity of South Africa’s research landscape.

Delivering the keynote address, Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation at the UFS, reflected on The Essence of Postgraduate Studies and Success in South Africa. He emphasised that postgraduate research plays a critical role in shaping innovation and addressing the country’s most pressing challenges. “As postgraduates, you represent a powerful tool of transformation, equity, and innovation, and every thesis is a story of resilience and a long journey of research,” he said. Prof Reddy also talked about how “competitions like the 3MT not only celebrate research excellence but also teach scholars how to communicate their ideas to inspire real-world impact,” praising the competition for opening opportunities for postgraduate scholars. 

The University of the Free State was represented by two candidates, Rentia du Plessis from the Faculty of The Humanities, who presented her 3MT title, Exploring Instructional Communication Strategic for Holistic Student Development, and Naquita Fernandes from the Faculty of Economic and Management Sciences, with her 3MT title, Triggering Online Review Generation Behaviour

Other universities, such as the Nelson Mandela University, Unisa, the University of KwaZulu-Natal, the University of the Western Cape, the University of Johannesburg, and the University of Pretoria, were also present.

After a series of captivating presentations, Robinah Nakawunde from Stellenbosch University claimed the top prize. Representing the Faculty of Medicine and Health Sciences, her presentation titled, Cured but Not Healed: Uncovering the Lung’s Struggles after TB, captured the attention of both the judges and the audience. Her research sheds light on how pulmonary tuberculosis continues to affect lung function even after successful treatment, highlighting the need for improved post-TB health-care interventions.

The first runner-up position went to Aaron Harvey from the University of Pretoria’s Faculty of Natural and Agricultural Sciences, whose research explores how avocado plants fight root rot disease using RNA interference mechanisms. His presentation, titled How Avocado Cells Fight Against the Root Rot Disease Caused by Phytophthora cinnamomi, Using RNAi Gatekeepers, impressed the judges with its clarity and scientific depth.

Morgan Lee from the University of Cape Town’s Faculty of Humanities took home the second runner-up prize. Her presentation, Locked In: The Hidden Barriers to Sustainable Agriculture, tackled the challenges facing South Africa’s commercial grain sector in transitioning towards more sustainable practices, offering insights that bridge environmental and social considerations.

The 2025 3MT National Competition once again demonstrated the power of concise, impactful communication in research. As the curtain closed, it was evident that South Africa’s future of research and innovation remains in capable hands, ones that can not only investigate deeply, but also explain passionately

Producers to save thousands with routine marketing strategies, says UFS researcher

Using derivative markets as a marketing strategy can be complicated for farmers. The producers tend to use high risk strategies which include the selling of the crop on the cash market after harvest; whilst the high market risks require innovative strategies including the use of futures and options as traded on the South African Futures Exchange (SAFEX).

Using these innovative strategies are mostly due to a lack of interest and knowledge of the market. The purpose of the research conducted by Dr Dirk Strydom and Manfred Venter from the Department of Agricultural Economics at the University of the Free State (UFS) is to examine whether the adoption of a basic routine strategy is better than adopting no strategy at all.

The research illustrates that by using a Stochastic Efficiency with Respect to a Function (SERF) and Cumulative Distribution Function (CDF) that the use of five basic routine marketing strategies can be more rewarding. These basic strategies are:
• Put (plant time)
• Twelve-segment pricing
• Three-segment pricing
• Put (pollination)(Critical Moment in production/marketing process), and
• Pricing during pollination phase.

These strategies can be adopted by farmers without an in-depth understanding of the market and market-signals. Farmers can save as much as R1.6 million per year on a 2000ha farm with an average yield.

The results obtained from the research illustrate that each strategy is different for each crop. Very important is that the hedging strategies are better than no hedging strategy at all.

This research can also be applicable to the procurement side of the supply chain.

Maize milling firms use complex procurement strategies to procure their raw materials, or sometimes no strategy at all. In this research, basic routine price hedging strategies were analysed as part of the procurement of white maize over a ten-year period ranging from 2002–2012. Part of the pricing strategies used to procure white maize over the period of ten years were a call and min/max strategy. These strategies were compared to the baseline spot market. The data was obtained from the Johannesburg Stock Exchange’s Agricultural Products Division better known as SAFEX.

The results obtained from the research prove that by using basic routine price-hedging strategies to procure white maize, it is more beneficial to do so than by procuring from the spot market (a difference of more than R100 mil).

Thus, it can be concluded that it is not always necessary to use a complex method of sourcing white maize through SAFEX, to be efficient. By implementing a basic routine price hedging strategy year on year it can be better than procuring from the spot market.
