Through collaborative agreements with the University of Malawi and the University of Zambia, the University of the Free State (UFS) has established the Research Alliance for Higher Education in Africa (RAHEdA), a dynamic initiative aimed at enhancing research capacity and partnerships within Sub-Saharan Africa.

The initiative forms part of the UFS’s SARChI Chair in Higher Education and Human Development (HEHD) research programme. 

The collaborative agreements align with the UFS’s Vision 130 strategy in relation to internationalisation, emphasising the important role that intra-African mobility visits play in establishing relationships with universities on the continent. It also fosters knowledge exchange and engagement and allows for careful planning and strategy meetings. 

In 2024, the HEHD hosted Dr Kapambwe Mwelwa, a lecturer in the University of Zambia’s Department of Educational Administration and Policy Studies, and Prof Chikumbutso Manthalu, Head of Higher Education and Professional Development in the University of Malawi’s School of Education, for such a visit. Their engagements included research seminars, a PhD presentation day, and collaborative strategy sessions with UFS academics, including Prof Faith Mkwananzi and Prof Mikateko Mathebula from the UFS’s Centre for Development Support (CDS), who are co-founders of RAHEdA.

“During these discussions, an ambitious but feasible roadmap was laid out for the next three to five years,” Prof Mkwananzi said. “These activities include online workshops for staff and postgraduate students at all partner institutions, and a new webinar series that focuses on profiling, advancing, and celebrating thought leaders, higher education scholars, and scholarship in Africa.” 

The inaugural webinar was held on 21 May 2025. Speaker Prof Siseko Kumalo, Associate Professor at the University of Johannesburg’s Ali Mazrui Centre for Higher Education Studies, spoke on ‘Orality as the Bulwark of the Humanities?’, set the bar high for the webinar series through his compelling and original response to this timely question, as scholars around the world contemplate appropriate responses to the rise and influence of artificial intelligence in higher education teaching, learning, and assessment.

Funding to support RAHEdA has been generously provided by Prof Melanie Walker, Distinguished Professor and SARChI Chair in Higher Education and Human Development.

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.
