Improving student well-being through collaborative food provisioning initiatives.

In commemoration of Nelson Mandela and his commitment to justice, human rights and fundamental freedoms, a profound belief in the equality and dignity of every woman and man, the University of the Free State (UFS) reflects on the university’s food gardening project, a collaborative initiative established to address student food insecurity in a sustainable manner. 

As stipulated in the 2021 UFS Food Environment task team report, food insecurity among students in the higher education sector has emerged over the past decade as a global threat to student success. According to the internationally accepted definition of food insecurity, these students experience limited or uncertain availability of nutritionally adequate and safe foods or have limited or uncertain ability to acquire acceptable foods in socially acceptable ways.

The UFS Food Environment Office, in collaboration with Kovsie ACT, the UFS Department of Nutrition and Dietetics, FARMOVS, Tiger Brands, Siyakhana Food Gardens and other businesses, has embarked on an 18-month journey to address this problem within the university. 

The project kicked off with the building of two large food tunnels that aid students with fresh produce on a regular but controlled basis. The project has received financial support from organisations including Tiger Brands, Siyakhana Food Gardens, and Sakata Seeds.

A recap of the UFS gardening project and food harvested

The gardens produced foods such as Swiss chard, beetroot, carrots, and cabbage that were consistently distributed to vulnerable students from March 2020 up until now. Onions, lettuce, and spinach also formed part of the food parcels prepared for students, accompanied by food donations from UFS staff and students, Tiger Brands, and the Shoprite Group through the UFS food bank.

In November 2020, a brainstorming workshop was held to reflect on the status quo of the UFS gardening project and the value it adds to a larger integrated food provisioning system at the university. The workshop addressed topics including the planting and production of relevant crops; processing and distribution of products harvested; and the creation of a training curriculum pertaining to the activities of the UFS gardening project.

“By creating our own food gardens, we share valuable knowledge with the rest of the team involved with this project and further uplift our communities. After all, small-scale sustainable food production could lower one’s environmental footprint and contribute to a healthier lifestyle,” stated Carien Denner from the UFS Department of Sustainable Food Systems and Development. 

Denner goes on to explain that the mutually beneficial relationship of all stakeholders involved in the maintenance of the food gardening project has the potential to expand in the future to further combat student food insecurity in a sustainable manner. 

What the UFS food garden project anticipates for the future

According to Denner, the food tunnels at Lengau will be moved to the Paradys experimental farm. One tunnel will be converted into a hydroponic system covered in plastic, and the other will be covered in netting and will be planted directly into the ground. Financial aid for the moving of the tunnels was provided by the UFS Dean of Natural and Agricultural Sciences and Prof Rudolf from the Siyakhana Food Gardens. 

The produce from these two tunnels will be sold to UFS staff and some will be distributed to students through the UFS No Student Hungry Programme (NSH). Denner mentioned that the team are further looking to empower students to grow foods at their own homes by involving them in the planting and harvesting process of the gardening project. 
The continuation of the food gardening project and other support initiatives facilitated by the Food Environment task team thrive through collaborations with businesses, NPOs, UFS staff and students, to address food insecurity and malnutrition among students. 

Staff and students are encouraged to contribute by collecting non-perishable food items for the UFS Food Environment Office.

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.
