Everywhere you look, our colleagues at the UFS are stepping up and stepping into the new digital space. With the move to virtual events, staff members at the university are able to participate in discussions and webinars across the continent at various other institutions of higher learning. 

One such virtual event recently took place for Women’s Month. The Tshwane University of Technology hosted the Annual Adelaide Tambo Memorial Lecture on 27 August. The theme was Is the face of the boardroom in global organisations changing women representation in influential positions?

Dr Phumzile Mlambo-Ngcuka, United Nations Under-Secretary General and Executive Director of UN Women, focused in her presentation on themes regarding girls’ education and women’s health, both of which have been threatened by the COVID-19 pandemic.

As the respondent, Dr Maria Madiope, Principal of the UFS South Campus, dealt with the patriarchal domination and violence that modern women and girls endure, as well as the way “their sexuality and aptitude is disrespected and how they are subjugated and side-lined in the political, corporate, social, and cultural arena.” She said that it is incumbent on the modern generation of women to reignite the flame that fuelled the struggle for feminine recognition and equality. “We are beholden not only to the legacy of those that came before us, but also to the eager eyes that look up to us,” she concluded. 

Dr Madiope also announced her support for Dr Mlambo-Ngcuka’s Generation Equality campaign against gender-based violence, and she echoed the sentiments of the rallying hashtag #JustChair, which breaks down discrimination based on the use of gendered terms such as ‘chairman’ for the leader of a meeting or corporation.

Dr Adelaide Tambo’s life was characterised by a love of knowledge, as she believed that people need as much power to be able to handle challenges facing the country, the continent, and the planet. She strove for the emancipation of women in general, focusing on the importance of education and how it can improve a woman’s life, and encouraged a strong culture of learning.

The event was livestreamed on Facebook and Zoom; go to https://www.facebook.com/805899996152814/videos/1036964343420927 to watch the full presentation.

“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.
