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.

Postdoctoral researcher, Abdon Atangana, of the Institute for Groundwater Studies at the university recently published an article online about the Lassa Haemorrhagic fever in the Natural Computing Applications Forum. In addition to the terminal transmissible sickness recognised as Ebola haemorrhagic fever, there is another strain called Lassa haemorrhagic fever.

The disease is classified under the arenaviridae virus family. The first outbreaks of the disease were observed in Nigeria, Liberia, Sierra Leone, and the Central African Republic. However, it was first described in 1969 in the town of Lassa, in Borno State, Nigeria.

The main host of the Lassa virus is the Natal Mulimammate mouse, an animal indigenous to most of Sub-Saharan Africa. The contamination in humans characteristically takes place through exposure to animal excrement through the respiratory or gastrointestinal tracts.

Mouthfuls of air containing tiny particle of infective material are understood to be the most noteworthy way of exposure. It is also possible to acquire the infection through broken skin or mucous membranes that are directly exposed to the infective material.

“The aim of my research was to propose a novel mathematical equation used to describe the spread of the illness amongst pregnant women in West Africa. To achieve this, I used my newly-proposed derivative with fractional order called beta-derivative. Since none of the commonly used integral transform could be used to derive the solution of the proposed model, I proposed a new integral transform called Atangana-Transform, and used it, together with some iterative technique, to derive the solution of the model.

“My numerical simulations show that the disease is as deadly amongst pregnant women as Ebola,” Abdon said.

Abdon’s research was submitted to one of Springer’s top-tier journals with an impact factor 1.78. The paper was accepted and published February 2015.
