GROW your own Food
KovsieACT and the Food Environment Office, together with the Department of Sustainable Food Systems and Development, presented a lunchtime event: GROW with food security activist, Thabo Olivier, at the Thakaneng Bridge on the Bloemfontein Campus.

There is nothing that says ‘spring’ quite like tree buds, blossoms, butterflies, and bees.

At the University of the Free State (UFS), spring was heralded this year by the dark red of beetroot, the orange of carrots, the green of fresh spinach, and the pale green of big, healthy cabbages, as staff and students celebrated GROW with Thabo Olivier on Spring Day. 

UFS research findings indicated that almost two thirds of its students do not know where their next meal will come from. One of the initiatives the university has created to address the issue, is a vegetable production and training programme. The purpose of the programme, which was established by Kovsie ACT in collaboration with the Department of Sustainable Food Systems and Development and the Food Environment Office, is to teach students how to produce vegetables.

In an effort to train the wider university community about food production in order to contribute to food security at the UFS, KovsieACT and the Food Environment Office, together with the Department of Sustainable Food Systems and Development, presented a lunchtime event: GROW, with food security activist, Thabo Olivier, at the Thakaneng Bridge on the Bloemfontein Campus.

Reuse and repurpose

Olivier, who believes in reuse, reduce, recycle, and repurpose, is of the opinion that one can transform one’s waste into a sustainable garden. He will use what people throw away – from bottles to eggshells to cracked drums – to grow his vegetables. He also makes his own compost and organic pesticides consisting of garlic, chilies, and onions, boiled in water. The extract is then poured through a sieve and sprayed onto his crops through his self-made spray bottle – an old plastic 2 L bottle with holes (made with a pin) at the top. 

According to him, no space is too small to grow food. He planted tomatoes in bottles and started his giant pumpkins of 300 to 400 kg in foamalite cups, later transplanting them into a bigger space.

Grow into it

Typing in ‘food insecurity’, one would find that a third of Pakistan is under water, meaning that a large part of their agricultural land has been washed away. According to the World Bank, record high food prices have triggered a global crisis that will drive millions more into extreme poverty, magnifying hunger and malnutrition. The global food crisis has been made worse by the growing number of food trade restrictions put in place by certain countries in reaction to the outbreak of the war in Ukraine. 

In Olivier's view, people can only be enslaved through food insecurity. It is his opinion that small organic farms are the start of saving the world. He is planning to create a 100% food secure street in Bloemfontein. He would like to extend this to other suburbs and later to other cities. “Start small with one square metre and grow into it,” he says.

Qualify yourself 

Olivier advised that it is important to equip yourself with knowledge. He recommended the short courses of the Centre for Sustainable Agriculture, Rural Development, and Extension at the UFS. “Furthermore, if you do not know anything, you have access to all the information on the phones in your pockets. Find out where your passion lies and qualify yourself,” he says.

Olivier shared his four food growing commandments. He says a person with an excuse will never be able to produce; it is only the person who prepare that will prevail; what you put in is what you get out (also in life); and the best time to start is now. 

Teaching others to grow their own food is an essential part of stopping world hunger. “Equip yourself with the knowledge and then teach someone else to plant their own food. If you want to be a leader, start teaching others to grow food. Lead by example and ensure food security,” he says

Harvest and taste

Carien Denner-Vorster from the Department of Sustainable Food Systems and Development did a food demonstration during which she made a beautiful coleslaw with cabbage and carrots from the gardens, which not only inspired students to make their own salad, but also provided the opportunity to taste. 

The GROW with Thabo event also included the harvesting of vegetables, more specifically cabbage and spinach, in the gardens opposite Welwitschia Residence. 

In 2019, Dr Jan Swanepoel, Senior Lecturer in the Department of Sustainable Food Systems and Development – with the help of Prof Michael Rudolph from the University of the Witwatersrand – obtained funding from Tiger Brands for two vegetable tunnels. Later, due to the success of the tunnels, Tiger Brands again assisted with the funding of two more tunnels on the UFS Lengau Experimental Farm. These tunnels are in the process of being completed. 

Through KovsieAct, students from the residences can volunteer to get involved in the vegetable production programme. According to Annelize Visagie from the Food Environment Office, up to 80 students, most from the No Student Hungry (NSH) Programme, receive food after each three-day harvest. Anyone who would like to contribute to the NSH programme, can contact her at visagiea@ufs.ac.za

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
