The Division of Student Affairs (DSA) prioritises innovation to meet the challenges of food insecurity and malnutrition among students. To this end, several student volunteers and student governance structures are collaborating with the DSA on various initiatives.
During 2019, various conversations were held about the possibility of creating a health-promoting food environment at the UFS where students and staff are well informed and empowered to take appropriate action regarding their food and nutritional needs. These conversations resulted in an institutional strategy to address the food environment at the UFS. Student representatives serve on a technical committee that directs the implementation of this strategy. In this regard, several initiatives have already been launched.
Students from residences and other student communities have planted vegetable gardens on the Bloemfontein Campus with the assistance of KovsieACT and the Faculty of Natural and Agricultural Sciences. Students and staff are already harvesting and distributing vegetables to needy students every week. Measurements were put in place to continue this during the COVID-19 period. The following vegetables were planted: spinach, cabbage, beetroot, broccoli, cauliflower, and carrots.
Food parcels, donated by Tiger Brands and Gift of the Givers, are continuously handed out by DSA staff and student volunteers. In this regard, 540 food parcels have already been handed out on the Bloemfontein Campus during the COVID-19 period alone. During the same time, 117 students received food parcels on the Qwaqwa Campus. The innovation of this food parcel project rests on the fact that business, NPOs, UFS students, and DSA staff are collaborating to address food insecurity and malnutrition.
More collaborative initiatives will be implemented over the next 12 months. The DSA staff and students are already working with the Department of Dietetics and Consumer Sciences to create information packages about the preparation of low-budget nutritious meals.

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.
