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

In an effort to combat food insecurity on campus, a vegetable production and training programme of the UFS not only provides its students with fresh produce, but it also gives them the opportunity to get involved on a voluntary basis in the food production process, including the planting and harvesting of the vegetables.

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

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including: Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained. The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5. The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small. In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
