The search for the 2019/2020 #KovsieCyberSta team has been an exciting one, with Anderson Mosia and Olebogeng Tlhong coming out tops to beat the competition.
Anderson, a second-year BA Languages student, didn’t let last year’s failure deter his efforts to enter again this year. 

“I am hoping to achieve a lot of things. My milestone would be to raise the bar high for the next stars; I've got a lot in store,” he says. 

He says he is passionate about spreading love, and he will use this new platform to express himself.

It has been first-time charm for first-year LLB student, Olebogeng. She says as soon as she saw the competition was open, she knew it was something that would fit her persona. 

“I am hoping to not only grow as an individual, but to leave my mark. The question that I asked myself before stepping into this role, was –what’s going to be different because you stepped in? I aspire to document and present events in the best way that I know, while being open to learning and, through my knowledge, inspire and teach others.”

The 19-year-old says she will use her passion for serving to express herself best over the next 12 months. 

“I believe that it is my duty to use the knowledge I have acquired/am to acquire in order to make somebody else’s life better. So essentially, I am a servant leader; I believe that there is enough room for everybody to succeed,” she adds.

As #KovsieCyberStas, the duo will cover events on and around campus, while filming and presenting short video clips to give fellow Kovsies some insight into these events across the UFS’s digital platforms.

“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.
