Liezel Rudolph believes opportunities do not fall into your lap, but you cross them when you do what you love, and you do it well.

On more than one occasion, Liezel Rudolph set foot on the SA Agulhas II, travelling the oceans to Marion Island in her quest to research climate change. She focuses her research on reconstructing the past climate of Marion Island. 

As Lecturer in Process Geomorphology in the Department of Geography Rudolph is involved in research on glacial and peri-glacial landforms, trying to understand the links between climate and the processes that shape these landforms.

An interview with her reveals more about this scientist, adventurer, and teacher who sees pursuing one’s research interests and teaching others about it as a dream come true.

 

“Part of being a woman is to know when to be strong and to speak up, and when to be humble and listen.” – Liezel Rudolph

Is there a woman who inspires you, who you would like to celebrate this Women’s Month?

“I would like to celebrate my mother who does everything to the full. She celebrates the little things; she dreams big and she does not fear the future. She values discipline, but nurtures growth and has always encouraged (me) to be the best version of me and not to compare myself to others.”

What are some of the challenges you have faced in your life that have made you a better woman?

“I don’t like being criticised and I don’t like failing. It has taken me several years to learn that not all criticism is negative and that not all failures are final. And that is OK. I have learned to be easier on myself, and on others when I (or they) don’t meet certain expectations.”

What advice would you give to the 15-year-old you?

“When I was 15 years old, I had no idea what life would be after school – and it scared me. I now know that by following my passion and doing what I am good at, I am doing myself and the world a favour. There is no point in making loads of money if you hate going to work every day. Opportunities do not fall into your lap, but you cross them when you do what you love, and you do it well.”

What would you say makes you a champion woman [of the UFS]?

“I would not say that I am a champion woman, yet. But I would like to think that I am a woman who does her job well, and who does ‘woman’ well, too. This means bringing what I have to the table, and not comparing, criticising, or competing with anyone about what else is on the table. I still have to grow a lot in this regard.”

“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.
