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

GROW your own food

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

Discovery in Scorpius constellation may signify clean energy for Earth

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
