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.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
