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.”

Fire as a management tool questionable in arid and semi-arid grassland areas

The influence of fire on the ecosystem in the higher rainfall ‘‘sour’’ grassland areas of southern Africa has been well established. However, less information is available for arid and semi-arid ‘‘sweet’’ grassland areas, says Prof Hennie Snyman, Professor in the Department of Animal, Wildlife, and Grassland Sciences, about his research on the short-term impact of fire on the productivity of grasslands in semi-arid areas.

Sour and sweet grassland areas can be defined as receiving either higher or lower than approximately 600 mm of rainfall respectively. In quantifying the short-term impact of fire on the productivity of grasslands in semi-arid areas, a South African case study (experimental plot data) was investigated.

“Burned grassland can take at least two full growing seasons to recover in terms of above- and below-ground plant production and of water-use efficiency (WUE). The initial advantage in quality (crude protein) accompanying fire does not neutralise the reduction in half of the above-ground production and poor WUE occurring in the first season following the fire.

“The below-ground growth is more sensitive to burning than above-ground growth. Seasonal above-ground production loss to fire, which is a function of the amount and distribution of rainfall, can vary between 238 and 444 kg ha -1 for semi-arid grasslands. The importance of correct timing in the utilisation of burned semi-arid grassland, with respect to sustained high production, cannot be overemphasised,” said Prof Snyman.

In arid and semi-arid grassland areas, fire as a management tool is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman said: “More research is needed to quantify the impact of runaway fires on both productivity and soil properties, in terms of different seasonal climatic variations. The information to date may already serve as valuable guidelines regarding grassland productivity losses in semi-arid areas. These results can also provide a guideline in claims arising from unforeseen fires, in which thousands of rands can be involved, and which are often based on unscientific evidence.”
