MESSAGE FROM THE RECTOR AND VICE-CHANCELLOR: UPDATE ON DEVELOPMENTS AT THE UFS

I hope you are well, healthy, and safe. I have experienced an overwhelming sense of commitment from staff and students across the university to make a success of the 2020 academic year. Thank you for working together towards this common goal.

Currently, we have a significant number of students back on the campuses in line with the university’s reintegration plan, and others are continuing with online learning. On 16 September 2020, President Cyril Ramaphosa announced that the country will move to alert Level 1 as from midnight on Sunday 20 September 2020. During Level 1 of the national lockdown, we will continue to return staff and students in a structured and phased approach according to the university’s reintegration plan. However, we are still unable to return all our students to the campuses, as we have to adhere to physical distancing and hygiene measures and also have to take into account the capacity of the lecture venues on the campuses, but most specifically the residences.

Please note that you will be informed by your faculty if you are required to return to campus during Level 1. If you have NOT been contacted, you will be supported through remote multimodal teaching, learning, and assessment until you are informed by your faculty that you can return to campus.

Data shows that most of you have adapted well to the blended learning modes – I find it admirable and inspiring. Rest assured that your lecturers are continuing to work hard to deliver a quality teaching and learning experience. Please use the #LearnOn material as a guide to plan for the second semester and engage with your lecturers on academic problems or consult with your faculty structures to find suitable solutions.

The university is aware that international students who have been residing outside of the country during Levels 5 and 4, may return to campus during Level 1; we will communicate with these students in due course.

I am confident that you are focused and committed to completing the second semester. We have prepared a safe environment for students who are returning to campus during Level 1. Sufficient hygiene measures are in place, as well as re-configurations to ensure physical distancing. The wearing of masks, physical distancing, and hand sanitising remain compulsory on all the campuses.

During Level 1, campus access will remain restricted – only those with campus access permits will be allowed to enter. Space in our residences remains limited due to physical distancing and residence students must comply with the protocols in their respective residences. See the Return to campus of students_Level 1 of national lockdown document for more information.

Although our country will be on Level 1 of the national lockdown, it is still extremely important that you remain vigilant and take ownership of your health and look out for the health of those around you. Ultimately, your health is your responsibility. Please do not let your guard down and adhere to the protocols and regulations – for your own safety, and for the safety of others.

It is also important to keep your mental health in check – make use of the #WellbeingWarriors campaign from our Department of Student Counselling and Development, which is aimed at encouraging health and well-being among students. Visit the COVID-19 website for comprehensive information and updates.

Although the infection rate in our country is decreasing, remember that the COVID-19 pandemic is still testing every aspect of society; we must not underestimate the impact that the pandemic still has on local and global communities. Take care of yourselves and those around you and comply with the national guidelines and regulations.

I wish you all the best with your studies.

“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.
