The UFS Food gardening project: a sustainable solution to food insecurity

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.

Nanotechnology breakthrough at UFS

2010-08-19

Ph.D students, Chantel Swart and Ntsoaki Leeuw

Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil.

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
