In a remarkable milestone for both her academic and personal journey, Dr Zandile Mncube, a 27-year-old newly conferred PhD graduate from the University of the Free State (UFS), recently presented her research at the prestigious International Mountain Conference (IMC2025), hosted by the University of Innsbruck, Austria. The event marked not only her debut on the global research stage but also her first international trip and first flight – an experience she described as transformative. 

 

A mountain of research: From UFS weather stations to the global stage

Dr Mncube's journey to this international platform began with encouragement from Prof Ralph Clark, Director of the Afromontane Research Unit, and Dr Melissa Hansen, Lecturer in the Department of Geography, who recognised her potential and urged her to submit an abstract to the conference. 

"Prof Clark proposed that I write an abstract for this conference," Dr Mncube explained. “I had been managing the UFS weather stations and had just begun using their data, so I based my abstract on that work.” 

Her submission was accepted, earning her the opportunity to showcase her research alongside an impressive array of global scholars. The IMC2025, held biennially, brings together experts from across the world to discuss diverse aspects of mountain studies. Dr Mncube formed part of a strong South African delegation that included two students from UFS and one from the University of Cape Town (UCT).

"It was inspiring to see how diverse and multidisciplinary the field is," she said. "It was good to see that, as South Africans, we do fit into the global research stage and can hold our own through the quality of our work.”  

 

Vision for the future: expanding research horizons 

Having been part of the UFS community since 2017 - serving in various roles from student assistant to her current practical and research position – Dr Mncube is now looking ahead to further her research career.

"I want to explore more on the research side of things," she shared. “While I’ve gained valuable experience that could lead to lecturing, my immediate goal is to deepen my involvement in research and fieldwork within Geography.”   

 

A transformative experience and a call for greater support

Describing her participation at the IMC as a "transformative experience, both professionally and personally," Dr Mncube reflected on how it broadened her understanding of global scientific collaboration and highlighted the vital contribution of African researchers. 

She noted there remain "notable gaps in data and contextual understanding that African researchers are uniquely positioned to address," particularly in underrepresented mountain regions.

Dr Mncube strongly advocates for more South African students to be supported in attending international conferences. She observed that several of her peers at the IMC had earned recognition through the Southern African Mountain Conference 2025 (SAMC), further illustrating the value of regional and international engagement. 

"If more students are supported to attend conferences like IMC, it could open doors for them to engage in global research and collaborations that extend far beyond our borders," she said. 

Expressing her heartfelt appreciation, she concluded by thanking Prof Clark and Dr Hansen for their guidance and support, which made her international debut possible.

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.
