Vegetable tunnels
Two vegetable tunnels were recently established on the UFS Bloemfontein Campus to contribute to the fight against food insecurity.

Food insecurity is a problem on university campuses worldwide. The three campuses of the University of the Free State (UFS) are not exempt from this plight. Research findings indicate that more than 64% of students at the university go through periods of hunger.

Annelize Visagie, , from the Division of Student Affairs who is heading the Food Environment Office at the UFS, confirms that food insecurity at higher education institutions is not a new phenomenon.

In a study with first-year students as focus, Visagie found that academic performance declines and coping mechanisms increase as the severity of food insecurity increases.

“Students use different coping mechanisms, with an alarming percentage of students (40,6%) using fasting as an excuse to friends for not having food, 60% of students skipping meals because they do not have enough money, and 43,2% of students being too embarrassed to ask for help.”

Visagie states that various factors contribute to this alarming scenario, with the main reason being that the majority of students come from impoverished economic and social circumstances. This suggests that although students receive NSFAS funding or any other bursary, it is not a guarantee that they are food secure.

Focus on student wellbeing
Aligning with the UFS strategic goal of improving student success and wellbeing, UFS staff is working hard to implement initiatives and obtain sponsorships and food donations to ensure that students do not go hungry.

Members of the university’s Food Environment Project, Drs Johan van Niekerk and JW Swanepoel from the Centre for Sustainable Agriculture, Rural Development and Extension (CENSARDE), and Karen Scheepers from the Division of Student Affairs who is heading KovsieAct partnered to move the existing vegetable tunnels on the UFS experimental farm to the Bloemfontein Campus.

The construction of the tunnels and boxes was financed by Tiger Brands. Professor Michael Rudolph and Dr Evans Muchesa who are involved with the Siyakhana Food Gardens, assisted with the training of students and consultation throughout the project.

The two tunnels (30 m x 10 m each) are covered with netting, and two water tanks with pumps are fitted to provide the necessary irrigation.

Vegetables add value
Dr Swanepoel explains: “In each tunnel there are 20 raised wooden boxes. Each residence received one box where they planted one type of vegetable crop, including Swiss chard, cabbage, carrots, beet, kale, and broccoli.”

Residence Committee members from all on- and off-campus student communities in civic and social-responsibility portfolios, as well as civic and social-responsibility student associations, received the necessary training to plant vegetables.

The vegetables were planted in mid-February and the first harvest is expected around mid-April.

This initiative, which will help students in the near future to keep the hunger pangs at bay in a healthy way, adds to the existing No Student Hungry programme. Visagie says it is important for the university to assist students in making healthy choices and to educate them on decisions to secure nutritional food for themselves.

In addition, the university also received food parcels from Rise Against Hunger, together with donations from organisations such as Gift of the Givers – providing 200 food parcels to students on the Qwaqwa Campus, and the recent donation from Tiger Brands – providing 500 food parcels to students.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
