If you are so focused on achieving only certain goals in your life, you might miss the best opportunities, believes Dr Walter van Niekerk, who recently received his PhD in Agricultural Economics.

Being relevant in a constantly changing agricultural environment. This is one of Dr Walter van Niekerk’s biggest motivations in his working life. The place where he believes he will be able to do just that, is the University of the Free State (UFS). “The university was the best plan for my life,” he says. 

Whether it is in research or in learning and teaching, Dr Van Niekerk, Lecturer in the UFS Department of Agricultural Economics, believes that with a positive attitude and the ability to be adaptable to change, one will be able to make the most of any opportunity crossing your path. If you give 110% every day, you will be ready for any possibility. He is lecturing Agricultural Finance and Agri-business Management, focusing on agricultural business plans, to first- and third-year students, respectively. 

Contribute to findings on predation management

At the recent April graduation ceremonies, he was awarded his PhD. The title of his thesis was: An estimation of the downstream economic implications of predation in the South African red meat industry.

In his thesis, he outlined the economic impact of predation in the livestock sector and red meat industry. He believes the significant damage caused by predators cannot be controlled by man-made borders. “There is a reason for these animals' existence; they just need to be managed properly at national level by government,” he says.

The aim of his study was to contribute to and combine any findings on the predation problem, and to put these findings on a macroeconomic platform to inform government of the extent of this problem in order for them to develop strategies, policies, and mitigation methods to reduce predation and lessen the impact thereof.

Thus far, excerpts from his thesis have also been published as two articles in peer-reviewed scientific journals – a peer-reviewed journal of the National Museum, Indago, as well as the journal, Frontiers in Sustainable Supply Chain Management.

With predation being a constant point of discussion at agricultural associations’ monthly meetings, he believes that the research topic he has selected for his PhD is relevant and that the outcomes of his study will be able to make a difference in the agriculture sector. His work is more than just theory. He identified a problem – the damage that predation does to the red meat industry – and found a practical solution to it.  

Students staying relevant in a fast-changing environment 

Besides the possible impact he will have on the red meat industry, the PhD was also a means to an end – to develop himself as an agricultural economist in order to become an industry expert in his field.

He also takes his role as lecturer very seriously. It is important to him that his students, once they have completed their studies, must have an actual understanding of the field and that they must be able to stay relevant in a fast-changing environment by practically applying what they have learnt. 

In his free time, Dr Van Niekerk enjoys applying his knowledge. Besides his consultancy work with farmers, he also serves on Free State Agriculture’s Young Farmer Committee, and he is a technical adviser to the National Lucerne Trust (NLT), assisting them with their grading processes to ensure that their quality system is free of any irregularities, and that they stay relevant in the industry.

A research project into low-energy lighting using phosphor materials for light emitting diodes (LEDs) at the Department of Physics at the University of the Free State (UFS) has received further recognition. 

The South African Research Chairs Initiative (SARChi) has awarded further funding for the Research Chair in Solid State Luminescent and Advanced Materials situated in the department. Prof Hendrik Swart, a Senior Research Professor in the Department of Physics, says this means that the Chair will carry on receiving funds from SARChi for another five years. The Initiative also awarded Prof Swart in 2012 for the research, which resulted in funding for equipment and among others, bursaries.    

Better light emission in LED’s
The research focuses on better light emission of phosphor powers in LEDs. It is also looking into improving LED displays in flat screens. The research into solar cells has shown that phosphors can also increase their efficiency by increasing the range of light frequencies, which convert into electricity. It also entails that glow-in-the-dark coatings absorb light during the day and emit it at night. 

Prof Swart says over the next five years the research will focus on developing and producing devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have.” In practical terms, it means they want a farmer’s water pump that works with solar energy to work better with less energy input.” 

Device that simulates sunlight
Prof Swart says the renewal of the Chair’s funding means the department can now get equipment to enhance its research   such as a solar simulator. The solar simulator uses white LEDs whose intensity output and wavelengths can be tuned. The output is measured in number of suns. It enables researchers to work in a laboratory with a device that simulates sunlight.     

According to Prof Swart the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field. 

About 10 postdoctoral researchers are working on the studies done by the Chair in collaboration with the Council for Scientific and Industrial Research. 

The Research Chair Initiative aims to improve the research capacity at public universities to produce high-quality postgraduate students, research and innovative outputs. The criterion for evaluating the department’s Chair includes aspects such as how much development has occurred over the past five years. The assessors look at features such as the number of students the research entity has trained and how many publications the research team has produced.
