KovsieFM programme manager joins SuperSport as field reporter
Sam Ludidi.

Sam Ludidi is no unfamiliar face on campus. He is currently busy with his second year of a BA Communication Science degree but started off as a BSocSc student five years ago. This KovsieFM programme manager recently joined the SuperSport team as a field reporter. He was selected from 70 candidates and recalls the phone call he received as the best he ever got. We checked in with him to see how he was enjoying the limelight.

It is difficult to choose between television and radio ... I think I prefer television. Then again, there’s a certain skill you need for radio because people don’t see you – that challenge intrigues me. But since I’m an expressive person, television allows me to express myself in full view of the audience.

Sport is my true passion, without a shadow of a doubt. I was born and raised in a sports-crazy house and always loved it – even watching the Proteas’ unfortunate loss to Australia in the Cricket World Cup when I was four. I’ve always loved cricket, but I just cannot keep myself away from rugby. Between the two sports, I’d probably lean towards rugby from an off-the-field perspective, and cricket if I’m on the field.

“You only have one chance
to make it work.”

Supersport Field Reporter

The best and worst thing about being a television presenter is that it is live. You only have one chance to make it work. When I get it right, I feel great, but on a difficult day, I am hard on myself. I’m still somewhat new to television, but the trick is to find out what makes me different from the rest. My character and charisma make me stand out.

I still can’t believe ... that I am doing my dream job, and it almost came out of nowhere. My incredible support structure from since before my TV presenter job still sticks with me. I learnt from my mother to glorify God with the work that I do, I know that He’s opened many doors which led to this and I cannot express just how blessed I am.

“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.
