East College - Eco Vehicles Team
Overall winners of the 2022 Eco-vehicle race, East College, hard at work to get their car ready for the race held at the Odeion parking lot on the Bloemfontein Campus.

For the first time, the University of the Free State’s 2022 Eco-vehicle race – held on the Bloemfontein Campus on 14 May 2022 – had students from all three campuses participating in the programme and race; a cup was awarded to the college with the best support.

Although the annual event did take place in 2021, only team members were allowed access to campus due to the COVID-19 pandemic and lockdown regulations, and therefore the race was streamed live. 

Karen Scheepers, Assistant Director: Student Life, said: “To have the students back on campus supporting their teams was incredible; this event will become bigger and better every year.”

With the Eco-vehicle race project, the UFS aims to use an innovative skills development approach that will enable students to develop basic knowledge and skills on sustainable energy.

This year, 130 undergraduate students enrolled for this co-curricular skills programme that runs for nine months and culminates in the Eco-vehicle race. A total of eight teams competed in the energy efficiency race, speed race, obstacle course race, and the main event – the endurance race. For the first time in the main event, the teams raced against each other for 18 laps. 

The winners of this year’s event were Central College (Akasia, Karee, Kagiso, Soetdoring, and Wag-’n-Bietjie residences) for Spirit Cup, South Campus took home the Pit Stop, North College won the Smart Lap, and South College won the Endurance Race. The overall winners of the Eco-vehicle race were East College (Legatum residence). 

The driver for East College, Lebakeng Motlotlo, said: “Even though I have always been part of the KovsieACT Committee in my residence, seeing that the focus this year was more on energy saving and saving resources, it pushed me to participate.”

Motlotlo believes the practice he and his team went through worked for them, as they were able to practise “how to turn, slow down around corners, and save energy”. 

“Our team was very dedicated and knew how to improvise when faced with challenges. As a small residence and most of us living off campus, the race taught us the importance of teamwork.” 

Motlotlo believes “initiatives such as the Eco-vehicle race are important, as we learn other skills outside of lectures, which we sometimes think are not important”.

Scheepers said the plan is to “grow the programme, motivate other universities to also invest in their students through this programme, and race to become a national and maybe an international event”.

“The programme adds value to the student experience to ensure that they do not only obtain a degree during their study period, but also undergo practical application of acquired knowledge and skills through real-life situations and meaningful learning encounters,” said Scheepers.

“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.
