The Afromontane Research Unit (ARU), the flagship research group of the University of the Free State (UFS) Qwaqwa Campus, has recently been granted R8,4 million to establish a Risk and Vulnerability Science Centre programme.
The Risk and Vulnerability Science Centre (RVSC) programme was established by the Department of Science and Innovation (DSI) as part of the Global Change Research Plan for South Africa and is funded by the DSI through the National Research Foundation (NRF). The RVSC will focus on the need to generate and disseminate knowledge about risk and vulnerability on global change challenges faced by local policy makers/ governance structures and communities in South Africa.
Invited to participate
Dr Ralph Clark, Director of the ARU, says the UFS, together with the University of Zululand and the Sol Plaatje University, has been invited to participate in Phase 2 of the RVSC programme. Dr Clark was approached by the DSI (on referral from the South African Environmental Observation Network – SAEON) in February 2020 regarding the potential for establishing a RVSC at the UFS Qwaqwa campus.
Subsequent interactions were held between the UFS and DSI, and in March 2020, the UFS formally accepted the DSI invitation. It has since been agreed that the RVSC: UFS will be hosted as a RVSC under the ARU umbrella, with dedicated personnel embedded at the UFS in this regard (internal processes and reporting) but reporting directly to the NRF regarding the RVSC.
Interest and support welcomed
Dr Clark welcomed this interest and support from the DSI-NRF, saying that the funds will further assist the UFS in growing its excellent and growing research portfolio and building more research capacity on this traditionally undergraduate-focused campus. “The RVSC will contribute to much-needed solutions in an area marked by major sustainability challenges and will assist in moving Phuthaditjhaba away from its negative apartheid history towards becoming a sustainable African mountain city,” says Dr Clark.

A research project into low-energy lighting using phosphor materials for light emitting diodes (LEDs) at the Department of Physics at the University of the Free State (UFS) has received further recognition.
The South African Research Chairs Initiative (SARChi) has awarded further funding for the Research Chair in Solid State Luminescent and Advanced Materials situated in the department. Prof Hendrik Swart, a Senior Research Professor in the Department of Physics, says this means that the Chair will carry on receiving funds from SARChi for another five years. The Initiative also awarded Prof Swart in 2012 for the research, which resulted in funding for equipment and among others, bursaries.
Better light emission in LED’s
The research focuses on better light emission of phosphor powers in LEDs. It is also looking into improving LED displays in flat screens. The research into solar cells has shown that phosphors can also increase their efficiency by increasing the range of light frequencies, which convert into electricity. It also entails that glow-in-the-dark coatings absorb light during the day and emit it at night.
Prof Swart says over the next five years the research will focus on developing and producing devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have.” In practical terms, it means they want a farmer’s water pump that works with solar energy to work better with less energy input.”
Device that simulates sunlight
Prof Swart says the renewal of the Chair’s funding means the department can now get equipment to enhance its research such as a solar simulator. The solar simulator uses white LEDs whose intensity output and wavelengths can be tuned. The output is measured in number of suns. It enables researchers to work in a laboratory with a device that simulates sunlight.
According to Prof Swart the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field.
About 10 postdoctoral researchers are working on the studies done by the Chair in collaboration with the Council for Scientific and Industrial Research.
The Research Chair Initiative aims to improve the research capacity at public universities to produce high-quality postgraduate students, research and innovative outputs. The criterion for evaluating the department’s Chair includes aspects such as how much development has occurred over the past five years. The assessors look at features such as the number of students the research entity has trained and how many publications the research team has produced.
