There is a notable quote by one of the most prolific and influential composers ever, that says: 

“The music is not in the notes,
but in the silence in between.”
- Wolfgang Amadeus Mozart

Mozart’s proclamation is relevant, now more than ever. In many cases, we may not realise that those who are more silent than others are most likely faced with adversity in terms of their mental health.

To counteract this silence, UFS Clinical Psychologist, Angela Vorster from the School of Clinical Medicine, devised the UFS Medical Students ‘Unplugged’ initiative as part of a larger campaign. Vorster says the campaign creates an opportunity to encourage students to reconnect with their soulful side.

“Each year we choose a mental-health issue and focus our theme on raising awareness – e.g. suicide awareness.” This year’s theme is ‘In my blood’ depression and anxiety awareness. Sadly, the 2020 ‘Unplugged’ event had to be cancelled due to the unfortunate (and mentally taxing) circumstances we are currently facing around the globe. Nonetheless, Vorster’s evident compassion and benevolence towards individuals’ mental health did not allow the pandemic to discourage her from finding innovative ways of keeping harmony.

“Once we all returned to a 'new normal', I invited our students to submit recordings of their music. This then became a channel of its own on YouTube – and we could not be prouder of our musically talented students.” According to Vorster, research and literature have established that music has a significant impact on relieving emotional distress and improving our moods. “It became evident during therapy sessions how important music is in helping our students express their emotions, relax, and also engage their creativity,” says Vorster.

With Mental Health Month inching it’s way closer, and World Suicide Prevention Day on 10 September, we should all embrace the ‘magic’ of music and the positive effects it has on our psychological and mental well-being. So, turn up the volume and defeat the silence in your life with your favourite music. Play an instrument, turn up the volume on your iPod, sing in the shower, or watch the UFS Students ‘Unplugged’ videos on YouTube; allow music to heal your ‘silences in between’.

“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.
