The Centre for Health Systems Research and Development (CHSR&D) at the University of the Free State (UFS) recently donated 500 masks to Rekopane Primary School in Botshabelo. This initiative was part of its pledge to donate 100 cloth masks to a previously disadvantaged primary school for every 1 000 of the first 5 000 completed questionnaires that formed part of a study survey examining people’s understanding of information about COVID-19 vaccines. The results of the study will be shared with stakeholders who are responsible for providing information about COVID-19 vaccinations.

It is known that a large number of people globally and in South Africa prefer not to be vaccinated. “There are many reasons for this, and we would like to find out where people are getting information about the COVID-19 vaccination, and whether they are able to understand this information, so that they can make an informed choice about getting vaccinated. We did this by asking people about their own health and COVID-19, where they have heard about the vaccine, if they understood this information, and whether they have had/would have the vaccine or not, as well as the reasons for this,” said Prof Michelle Engelbrecht, Director of CHSR&D. 

While following guidelines such as wearing masks, sanitising hands, and social distancing are important to prevent the spread of COVID-19, a large percentage of the population will need to be vaccinated if we want to control the pandemic in the long term and prevent hospitalisation and severe illness. 

All persons in South Africa aged 18 and older were invited to complete an online survey regarding their perceptions of COVID-19 vaccines. The survey, which was available in the seven most spoken languages in the country, was advertised on social media platforms such as Facebook and Twitter, and on the Moya app.  The survey was open from 1 to 31 September 2021, and the CHSR&D received 10 554 completed questionnaires.  No data was required to complete the survey.

The Department of Basic Education partners decided on the school that would benefit, and the study provided an opportunity to support Bloemshelter, a UFS flagship programme. Alfi Moolman of the Directorate: Community Engagement said that “NGOs are really struggling to make ends meet, and we are delighted that Bloemshelter could provide the masks as one of their income-generating projects.  So many lives are touched for the good. The university is indeed a caring organisation.”

“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.
