Lefébre Rademan
Lefébre Rademan, new captain of the Free State Crinums netball team, could be one of the star players in the Premier League. She is a fifth-year Education student.
The Free State Crinums netball team, a de facto Kovsie team with all 15 squad members enrolled for courses at the University of the Free State (UFS), will draw inspiration from their success in last year’s Varsity netball tournament. The Kovsies won the student competition for a record third time. 

During the weekend of 10 May 2019, the Crinums will play their first match in the 2019 Premier League. They lost a couple of key players in captain Alicia Puren, Protea Khanyisa Chawane, (both playing for the national invitational team in the league), Khomotso Mamburu (moved to Cape Town), and Meagan Roux (injured). They do, however, still have the services of players such as Tanya von Berg (playing in her sixth Premier League, one of only a handful of players to do so), Lefébre Rademan, Sikholiwe Mdletshe, Ané Retief, Gertriana Retief, and Rieze Straeuli. Rademan is the new captain and was one of the standout players in last year’s Varsity netball, earning three Player of the Match awards, including the Player of the Final. 

The team will again be coached by Burta de Kock, who is also the head coach of the Kovsies. Under her leadership, the Crinums won the Premier League for the first three years (2014 to 2016). Last year, the Crinums ended fourth. De Kock will be assisted by Martha Mosoahle-Samm. She is a former Protea assistant coach who also captained South Africa and played for the UFS between 1997 and 1999.

There are four first-year students in the squad of 15 players: Oageng Khasake (wing attack), Ancia Pienaar (goalkeeper), Rolene Streutker (goal shooter), Boitumelo Mahloko (goal defence). Pienaar and Mahloko both represented South Africa at junior level in 2018.

■ Crinums squad: Ané Retief, Gertriana Retief, Jana Scholtz, Lefébre Rademan, Sikholiwe Mdletshe, Tanya von Berg, Rieze Straeuli, Claudia van den Berg, Zandré Smit, Oageng Khasake, Bianca de Wee, Ancia Pienaar, Rolene Streutker, Chanel Vrey, Boitumelo Mahloko.

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.
