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.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.
Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.
The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).
According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.
In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.
“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.
H.E.S.S. has issued a complete statement about the paper published in Nature.
