Prof Marian Tredoux is a geochemist and lecturer in the Department of Geology at the University of the Free State (UFS). Her research interests are rocks, particularly the chemistry of rocks and the minerals they are composed of – chemicals similar to those found in laboratories, although they occur in nature.
Prof Tredoux started her research career at the University of the Witwatersrand (Wits), after which she spent a number of years at the University of Cape Town (UCT). For the past 11 years, she has been at the UFS, which has brought her in close proximity of her primary field-research area in Barberton. This fascinating part of the country has been the focus of her research for 30 years. She has always been intrigued by the earth's crust in this area, which she describes as "very old, very strange, and very interesting".
Prof Tredoux has been collaborating with colleagues and peers overseas in an attempt to unravel the intricacies of this unusual geological area. Some of these colleagues recently discovered a new mineral in one of the rock formations of the Barberton mountain range. They decided to name the mineral after Prof Tredoux, dubbing it tredouxite. "I am very honoured by this, and very grateful that all these years of collaboration are being acknowledged," Prof Tredoux said.
DiMTEC hosts second conference on disaster risk reduction

Dr Anthony Turton, the Director: TouchStone Resources (Pty) Ltd. delivered the opening address at this year’s two-day annual international conference on disaster risk reduction that was presented by the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State (UFS).
In his presentation: Sitting on the horns of a dilemma: South Africa and its strategic water supply, he said: “We have simply reached the limit of the water resources in South Africa. On the one hand, we deal with the quantity dilemma in terms of strategic water storage. South Africa and Zimbabwe counts under the top 20 countries in the world in terms of dams built. We can only build about ten more dams.”
“On the other hand, we must deal with quantity. Previous solutions are not future solutions. When water is recycled, hormones such as oestrogen do not disappear. We must become creative and do something else,” he said.
“Science can make a difference. The UFS is well placed in terms of its groundwater research. Universities must invest in the necessary technology because the testing of toxins is essential. We must work in ways to prevent toxins from re-entering the water cycle,” he said.
A number of international speakers such as Dr Fabrice Renaud, Associate Director at the United Nations University’s Institute for Environment and Human Security (UNU-EHS) in Bonn, Germany, Dr Eugene Poolman, Chief Forecaster: Disaster Risk Reduction, South African Weather Service, and Prof. Rob Bragg from the Department of Microbial, Biochemical and Food Biotechnology at the UFS, attended the conference, as well as attendees from 11 different countries.
At the conference were, from the left: Mr Andries Jordaan, Director: DiMTEC at the UFS; Dr Ing Jörn Birkmann, Head of Section: Vulnerability Assessment at the United Nations University’s Institute for Environment and Human Security (UNU-EHS); Dr Anthony Turton, Director: TouchStone Resources (Pty) Ltd.; and Dr Fabrice Renaud, Associate Director: UNU-EHS.
