Prof Hendrik Swart
Prof Hendrik Swart from the UFS Department of Physics was recently recognised by the Golden Key Honour Society Southern Africa as one of South Africa’s 300 most influential leaders.

Prof Hendrik Swart from the University of the Free State (UFS) Department of Physics was recently honoured at the Golden Key Honour Society Southern Africa’s Black Tie Gala Event, held on 23 May 2025. The event celebrated 300 of South Africa’s most influential leaders across academia, industry, government, and the financial sector.

Prof Swart, who is an NRF B1-rated researcher and currently also holds the SARChI Research Chair in Solid-state Luminescent and Advanced Materials (2023-2027), described the recognition as both meaningful and affirming at this stage of his academic journey.

“Being recognised by such a prestigious organisation is a meaningful acknowledgment of my academic efforts and personal dedication,” he says. “It was a moment of validation and inspiration, reminding me that hard work truly pays off.”

While the exact selection criteria were not publicly detailed, the emphasis was placed on academic excellence, scholarship, and leadership.

This is not Prof Swart’s first recognition from the Golden Key Honour Society. In 2012, the UFS student chapter awarded him honorary membership for his contributions as a mentor and supervisor – an early nod to his lasting impact on student success.

“The student chapter here on campus gave me some recognition by awarding me honorary membership,” he recalled. “It meant a lot to me as a mentor.”

The gala itself offered more than accolades – it created a space for meaningful exchange. Prof Swart reflected warmly on reconnecting with one of his former students from the early 2000s, calling it a highlight of the evening.

Looking ahead, Prof Swart welcomed the society’s plans to continue this initiative across the country.

“This was the first time they had an event like this, but more are expected to follow. I see it as a good initiative to mingle with other sectors in South Africa.”

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
