Afromontane Research Unit welcomes new Director
Newly-appointed Afromontane Research Unit Director, Dr Vincent Clark.
The newly-appointed Director of the Afromontane Research Unit (ARU) on the Qwaqwa Campus, Dr Vincent Clark, is a true believer in risk-taking as a way of improving one’s life.

“Taking risks grows one’s confidence and experience, and at the right time the right door will open,” he asserts.

Dr Clark has his foundation in Geography and Botany; in 1998, he graduated with a BSc degree majoring in these two subjects, and he also has an Honours degree (1999) in Geography and Environmental Management; both degrees were obtained at the University of Johannesburg (the then Rand Afrikaans University).
 
“Then in 2010, I graduated with a PhD in Phytogeography at Rhodes University.  My PhD was followed up by several postdoctoral fellowships from Rhodes University and one at the University of Zürich between 2010 and 2016. I was privileged to become a lead academic in Professor Nigel Barker’s Great Escarpment Biodiversity Research Programme,” said Dr Clark, who is currently enjoying a good read of John Hunt’s The Ascent of Everest and Spiritual Leadership by Henry and Richard Blackaby.

He envisions the ARU as the continental leader in African mountain research, with an immediate focus on the sustainable development of the Maloti-Drakensberg.
 
“My immediate plans for the ARU team are to grow a strong network of between 60 odd researchers and postgraduates, and to connect them with the regional mountain-research community. Short-term plans include fostering stronger ARU links with the Swiss mountain-research community, encouraging the Japan collaboration, and an ARU-hosted Regional Mountain Conference.”

 “Longer-term plans are to develop the ARU into the leading African mountain-research group and for the ARU to become a leading South-based agent informing the global mountain-research arena,” he added.

Dr Clark has very strong words for the academia. “Academia must always guard against becoming a community of ‘yes men’ for external political or social agendas. As academics, we have a duty to discover and present the truth, regardless of how unpopular that might be. We are in serious danger of losing our academic mandate when we simply become a rubber stamp for untested politically-correct assumptions and agendas. If we ever needed bold academics to expose the plethora of ‘Emperors New Clothing’ currently on parade, it’s today.”

This family man and father of a one-year old son, loves the outdoor life. His hobbies include birding, hiking, swimming, surfing, and reading Louis L’Amour and Hammond Innes.

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.
