Prof André Roodt
Prof Andreas Roodt was recently awarded the MT Steyn Prize for Natural Science and Technology Excellence from the SA Akademie vir Wetenskap en Kuns. He will receive the prize, sponsored by Sanlam, at a function scheduled for September this year.

Prof Andreas Roodt, former Head of the Department of Chemistry at the University of the Free State (UFS) and retired Distinguished Professor in the same department, was recently awarded the MT Steyn Prize for Natural Science and Technology Excellence from the SA Akademie vir Wetenskap en Kuns.

The prize, a major recognition of his life's work, was presented to him for his contribution to the exploration and sustained development of natural science and technology and the successful application thereof in broader society.

Impacting society

About receiving the prize, he says it was a big surprise, but he is very proud to be honoured with this special award, “being an Afrikaans kid from a ‘platteland’ school outside Bloemfontein.”

Prof Roodt’s research focuses on understanding the reaction mechanisms of mainly inorganic coordination chemical systems that are critical to different industrial, medical, environmental, and metal beneficiation processes.

His research, for instance, contributes to important compounds and processes relevant to nuclear medicine and potential cancer therapy. Not so long ago, he registered a patent on this in Europe, Japan, and the USA that could help to diagnose and potentially treat cancer-related tumours in the future.

In addition, he continues to work on several projects aimed at developing cleaner industrial processes in the South African petrochemical industry. He is also focusing on more efficient ways of accessing the country’s mineral resources.

Career highlights

Throughout his academic career, Prof Roodt has achieved many significant milestones. He was extensively involved in crystallography for more than 30 years. One of his career highlights was being elected as the President of the European Crystallographic Association from 2012 to 2015, an organisation with more than 35 member countries.

In this field, he established an X-ray crystallographic facility in the UFS Department of Chemistry, which was officially named the ‘Roodt XRD Lab’ at the end of 2021.

He also sees his journey with the diverse group of 41 PhD and 54 MSc students (Afrikaans, English, Sesotho, Setswana, and isiXhosa) as another notable achievement in his career.

Other outstanding moments in Prof Roodt's career were his collaborations with research leaders from countries such as the USA, UK, Switzerland, Italy, Sweden, France, Croatia, India, Japan, Russia, the Netherlands, Germany, and Tunisia. These collaborations have allowed him to be recognised by peers worldwide and have demonstrated that Africa and South Africa can produce high-quality and relevant research that can compete on an international level.

The future

Despite his appointment as a Distinguished Professor and his commitment to finishing uncompleted work and assisting younger colleagues both in South Africa and abroad, Prof Roodt retired more than a year ago. He is now enjoying his retirement with his wife, children, and grandchildren, while also devoting time to his passion for collecting aloe plants and generating new hybrids.

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.
