UFS and CUT joint SASUF Research Symposium discusses urbanisation

The University of the Free State (UFS) and the Central University of Technology (CUT) recently joined hands with the Swedish University Forum (SASUF). The universities jointly presented at a research seminar with the theme: ‘Urban Rural Dynamic’. The seminar was a side event to the stream ‘Urbanisation in the 21st Century’ of the SASUF Sweden-South Africa Research Week that took place in the same week. This stream of the research week was academically chaired by Wanda Verster from the UFS Department of Architecture. 

SASUF is a collaboration of 30 universities in Sweden and South Africa together with embassies, civil society organisations, funding agencies and ministries in both countries of which CUT and UFS are partners. Other themes of the research week were ‘Climate Change, Natural Resources and Sustainability’; ‘Transforming Higher Education Curricula’; ‘Social Transformation Through Change’; ‘Understanding the Burden of Disease’; and ‘Digital Technologies, Big Data and Cybersecurity’. One of SASUF’s main goals is to connect researchers with funding agencies, industry, ministries, and society in working towards the Sustainable Development Goals. 

Tri-partite between local and international universities
The first day of the event was hosted by the UFS Department of Architecture on the Bloemfontein Campus and was supported by the UFS Department of Urban and Regional Planning

The focus of the seminar was on the rural/urban dynamic that secondary cities are frequently experiencing.

Researchers from the UFS, CUT and Malmö University in Sweden presented at the seminar. Stuart-Denoon Stevens, an honours student from the Department of Urban and Regional Planning at the UFS, presented his research on human settlements. “There are 200 million informal settlements in Africa. In 1994 there were 260 informal settlements in South Africa. Today we have 2600 informal settlements,” said Stewart. 

Take hands, not handouts
He believes that one needs to support what is happening rather than introduce new technology all the time. “Take hands, not handouts,” he said. 

Presenters from the CUT included Dilip Das, who presented on sustainable urban roads and transport, as well as Oke Saheed, who gave an overview of research on sustainable water resources and environment. Prof Nils Ekelund, the head of the Department of Science, Environment and Society at Malmö University in Sweden, presented on perceptions of the ecosystem services concept. He presented together with his colleague, Per Schubert, a lecturer in physical geography. 

The Director: Internationalisation at the UFS, Cornelius Hagenmeier, stressed in his welcoming remark the contribution SASUF and the side event organised by UFS and CUT make toward comprehensive internationalisation and strengthening the local collaboration between the two universities in Bloemfontein.

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.
