The African Mountain Research Foundation (AMRF), in association with the Afromontane Research Unit (ARU) of the University of the Free State (UFS), and the Global Mountain Safeguard Research Programme (GLOMOS), is hosting the first-ever Southern African Mountain Conference (SAMC2022). The theme of the conference is Southern African Mountains – their value and vulnerabilities.

The conference will bring relevant people together into one space for networking and information sharing, leading to more robust regional and international collaborations and comparative mountain studies with an increase in research activities, student capacity, researcher capacity and academic outputs that feed into policy and action. 

The conference will take place from 14 to 17 March 2022 in the majestic Maloti-Drakensberg Mountains in South Africa and Lesotho. 

According to the SAMC2022 website, this is a truly Southern African regional mountain conference, targeting the African region south of the Congo rainforest (DRC) and Lake Rukwa (Tanzania), but including Madagascar, the Comoros and the Mascarenes (i.e., Angola, the Comoros, the Democratic Republic of the Congo [southern mountains], Eswatini, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, La Réunion, South Africa, southern Tanzania, Zambia, and Zimbabwe).

Dr Ralph Clark, ARU Director, said the conference would be a high-level international event with UNESCO patronage and very valuable sponsors.

“The programme will have six parallel tracks (one being dedicated to postgraduate students), with about 200 papers being delivered. In addition, we have some very high-profile special sessions, such as an MRI special session on long-term monitoring activities and associated data availability for climate change-related applications across Africa’s mountains, as well as a UNESCO special session on regional collaboration. We also have Prof Julian Bayliss, described as the man who discovered an unseen world, as the guest speaker at the closing event.”

The conference will bring together relevant people in one space for networking and information sharing, leading to more robust regional and international collaborations and comparative mountain studies, with an increase in research activities, student capacity, researcher capacity, and academic outputs that feed into policy and action.

The GLOMOS team, one of the long-term partners of the ARU, spent the week of 8 to 11 March 2022 on the Qwaqwa Campus to strengthen collaboration and pave the way for new research opportunities in Phuthaditjhaba and the Maloti-Drakensberg.
GLOMOS represents an interface between the United Nations University Institute for Environment and Human Security (UNU-EHS) and Eurac Research. Postdoctoral fellow, Dr Stefano Terzi, said: “It’s very interesting for us to look at the Maloti-Drakensberg area because of its diversity. We are in the process of really exciting collaborations.”
Their projects include an understanding of the root causes of land degradation and improving decision-making processes for current water management within the context of water scarcity in the Maloti-Drakensberg.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

17 September 2013

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
