Takudzwa Nyamunda.

Takudzwa Nyamunda is the proud new representative of the University of the Free State (UFS) for the 2020 Commonwealth Future Student Leadership programme. Nominated at a recent workshop themed ‘Reimagining Peace’, organised by the Association of Commonwealth Universities in collaboration with the British Council and the Durban University of Technology, Takudzwa demonstrated exceptional leadership, coupled with his experience of issues related to the UFS student committee, which provided the perfect foundation for his selection. 

“From a personal point of view, this was one of the most enriching experiences I have ever had, both in terms of the relationships established and the world knowledge gained. I am personally grateful for the opportunity to attend and would support any further initiative of this nature. I think the essence of this workshop was to encourage the young leaders present – all of whom were active citizens in their communities in one way or another – to continue fighting the good fight. The core message from the panellists was that it is all worth it in the end, and that even in the face of adversity and discouragement, we should keep fighting for the work we believe in,” says Takudzwa. 

Participants from 13 nations, including activists and thought leaders on non-violence affiliated with the International Centre of Nonviolence, the Gandhi Development Trust, and the Commonwealth Countering Violent Extremism Unit, contributed to the workshop. Over the course of three days, participants were divided into five groups and worked together on projects linked to three main themes – gender-based violence, global warming, and inequality.

The selection committee was convened by the Vice-Rector: Research and Internationalisation, Prof Corli Witthuhn, and facilitated by the Office for International Affairs. Currently in the final year of his Master of Industrial Psychology degree, Takudzwa’s wealth or experience includes being the founder and first president of the International Students Association (2016), and holder of the International Student portfolio as Student Representative Council (SRC) member (2017), coupled with being co-founder and first vice-chairperson of the South African Board for People Practices (SABPP): UFS Chapter and Vice-president of the SABPP National Youth Council (2019).

“I will continue to do what I have been doing for the past five years at the UFS, which is to make a difference in my sphere of influence”, says Takudzwa.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
