Siphila Dlamini
Siphila Dlamini represented the UFS at the 15th Southern Africa Scout Youth Forum.
During the short April holidays, first-year BA student, Siphila Dlamini, led and participated in the 15th Southern Africa Scout Youth Forum and the 41st Southern Africa Scout Conference. Siphila previously also represented South Africa in the 8th and 13th World Scout Youth Forums in Baku, Azerbaijan and Harare, Zimbabwe respectively. He also participated in the 2018 International Leadership Training in Lilongwe, Malawi.

Siphila was elected as a member of the Southern Africa Youth Committee for the term 2017-2020, with the mandate of representing young leaders in decision making and youth engagement at Zonal level of the Southern Africa Scout Youth Forum.

He formed part of the forum committee and chaired several sessions of the proceedings since the tender age of 14. Youth leaders from Southern African Development Community (SADC) countries such as Botswana, the Kingdom of Eswatini, Malawi, South Africa, Mozambique, Namibia, Zambia, and Zimbabwe attended the conference. 

This 15th forum was themed ‘The Role of young people during emergencies’. Throughout the forum, young people deliberated on strategies to improve decision making in national scout organisations within their respective countries. The Southern Zone Youth Forum empowers young people by equipping them with good decision-making skills and increasing youth engagement on the African continent. 

According to Siphila, the Southern Zone Youth Forum is an effective tool for youth engagement and the continuation of skills development among young people in Southern Africa. It allows the youth to reflect on their growth and achievement, while broadening the unique impact of scouting in the world.

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.
