15 June 2021 | Story Dr Nitha Ramnath

Prof Francis Petersen, Rector and Vice-Chancellor of the University of Free State, South Africa, invites us to rethink our relationship with the world in a series of ‘Courageous Conversations’ on the theme of ‘The Global Citizen’.

Prof Petersen argues that COVID-19 has been a powerful ‘disruptor’ - it has given us a stark reminder of the need to rethink our identity, of where we belong, our ‘normative’ view of citizenship – if we want to secure long-term survival of our civilisation and the environments which support it.

Powerful voices from public life, intellectuals, public interest and business leaders, academics, naturalists, religious leaders, astrophysicists, economists, and ecologists, and others, will be invited to share and debate their views.

Global Citizen courageous conversation launch
In partnership with the South African Chamber of Commerce based in the United Kingdom, the series launched on 26 May 2021, in a discussion with Prof Petersen on the concept and context of his thinking and how the series will roll out.

If you were unable to join the webinar you can watch the replay on YouTube, or visit the South African Chamber of Commerce website where you'll find recordings of previous webinars.

Join our next Global Citizen conversation on 17 June 2021 with a discussion led by the Chancellor of the University of Free State, Prof Bonang Francis Mohale, a published author and respected business leader who has held chairmanships and directorships at some of South Africa’s top companies, on how we educate for Global Citizenship.

Educating a ‘Global Citizen’ – June 17, 2021 15:00 SAST
We have pleasure in inviting you to the United Kingdom - South African Chamber of Commerce’s next ‘courageous conversation’ with University of Free State Rector and Vice-Chancellor Prof Francis Petersen in his series debating ‘The Global Citizen’.  

Eminent South African business leader and UFS Chancellor, Prof Bonang Mohale, will join Prof Petersen to unwrap the role universities can play in creating a ‘Global Citizen’ mindset to effect material change in a constantly evolving and turbulent international world.  

How do universities produce research, and graduate alumni who go out into the  world, to drive and reflect the bedrock value of Global Citizenship namely that of mutual respect, for others, for all creatures, and the environment which sustains us all?

A university education can be a powerful way to push the ‘reset’ button on the baggage of upbringing and our histories - personal, cultural, national, racial – which shape our world view.  

Universities can promote informed self-reflection, curiosity, and tolerance as a driving force in how we shape our realities, understand our prejudices, promote tolerance, and animate life in a better world.  Prof Petersen and Prof Mohale will reflect on how universities can accelerate and respond with greater agility to this challenge.

Kindly RSVP for the event.

“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.
