SSAG 2023
The Department of Geography on the UFS Qwaqwa Campus recently played host to the Society of South African Geographers Conference (SSAG 2023), which gathered more than 100 students over three days.

Fostering academic growth, collaboration, and inspiration among students and researchers in the field of geography, the Department of Geography on the UFS Qwaqwa Campus recently played host to the Society of South African Geographers Conference (SSAG 2023), which gathered more than 100 students over three days.

Following a five-year hiatus, the three-day conference comprised student proposal presentations in different fields: human geography, environment geography, geoinformatics, and physical geography, divided into breakaway sessions over two days. Furthermore, day three of the annual conference included an excursion to the Basotho Cultural Village and Clarens. 

The three-day annual student conference focused on different themes presented by two main speakers. The topic of the first keynote speaker, Dr Mahlomola Daemane, General Manager of the SANParks Arid Research Unit, focused on the contemporary conservation, transition, and relevance of science in policy and decision making. 

The second keynote speaker was Dr Felicia Akinyemi, a Marie Sklodowska-Curie Research Fellow affiliated with the Institute of Geography at the University of Bern in Switzerland. Her work focuses on the intersection of geoinformatics, global change, and sustainability. Dr Akinyemi focused her talk on the integrative geospatial methods and metrics for sustainable land use. She introduced different techniques and metrics and gave students insight in early-career African research.

Speaking about the success of the conference, Nthebohiseng Sekhele, Geography Lecturer on the Qwaqwa Campus and chair of the organising committee, said, “The local organising committee was also very impressed with the quality of presentations from our postgraduate students in Geography, as well as the robust discussions that happened during the parallel sessions in the two days of the conference. We had a positive response of physical and online participation from many universities across South Africa. We are pleased that we have achieved our goal with this conference, which is to inspire the next generation of geographers.”

Extending new discoveries in the deep subsurface – UFS paper published in Nature Communications
2015-11-30



Scanning electron microscopy of some of the Eukarya recovered from two different mines. (a) Dochmiotrema sp. (Plathyelminthes), (b) A. hemprichi (Annelida), (c) Mylonchulus brachyurus (Nematoda), (d) Amphiascoides (Arthropoda). Scale bar, 50 µm (a,b), 100 µm (c), 20 µm (d).

Following the discovery of the first Eukarya in the deep subsurface (Nature, 2010) by a research group from the Department of Microbial, Biochemical, and Food Biotechnology at the University of the Free State (UFS) and their international collaborators, intense interest has developed in understanding the diversity of more complex organisms living in these extreme environments.

Prof Gaetan Borgonie from Extreme Life Isyensya, together with a group of UFS researchers, took this research further, resulting in a paper on this research released in Nature Communications – impact factor 11.47.  This paper is an extension of the first reports of more complex life at great depths, and their abilities to survive these harsh conditions.

Ten authors from the UFS contributed with the array of expertise needed to define this discovery. The group was supported by staff from the different mining groups, long-term leading collaborators from the USA and Canada, and the idea specialist driver of the paper, Prof Borganie.

“After a sampling campaign that lasted more than two years, we identified that Platyhelminthes, Rotifera, Annelida and Arthropoda are thriving at 1.4 km depths in fissure water up to 12,000-years old in the South African mines of Driefontein and Kopanang,” said Prof Borgonie, who was appointed as associated researcher in the Department of Microbial, Biochemical, and Food Biotechnology.

This paper really opens a “can of worms” so to speak. According to Prof Esta van Heerden from the Department of Microbial, Biochemical and Food Biotechnology at the UFS they extended to define protozoa and fungi. “However, they are present in low numbers,” she said.

Characterisation of the different species reveals that many are opportunistic organisms. In house-adapted video equipment was used to film inside the fissure for the home of the organisms.

This is the first-known study to demonstrate the in situ distribution of biofilms on fissure rock faces using video documentation. Calculations suggest that food, not dissolved oxygen, is the limiting factor for population growth. The discovery of a group of complex multicellular organisms in the underground has important implications for the search for life on other planets in our solar system.
