Intsika Food Garden
The newly redeveloped Intsika Garden on the UFS Qwaqwa Campus, designed to promote accessibility, sustainability, and community engagement. The garden's flexible spaces offer opportunities for students to relax, collaborate, and connect with one another.

The UFS Qwaqwa Campus is transforming its landscape to provide more than just a physical connection between buildings. The redevelopment of the garden in front of the Intsika Building marks a shift towards integrating communal spaces that support interaction, inclusivity, and sustainability. 

According to Nico Janse van Rensburg, Senior Director: Facilities Planning at University Estates, the primary aim of the redevelopment is to celebrate the diversity of the university as its ‘greatest asset’ by creating spaces that promote community engagement. “Previously, the garden was underutilised and did not connect properly to the rest of the campus’ circulation network. We identified an opportunity to develop it into a social space where academia and visitors can connect,” Van Rensburg explained.  

Accessibility and sustainability  

The Intsika Garden redevelopment aligns with the broader strategic goals of the institution, particularly in infrastructure planning. The project focuses on making the space universally accessible, ensuring that it caters for people with disabilities while improving overall circulation on the campus. “The development strives to improve the accessibility to different functions on the campus by making the space and circulation routes universally accessible,” said Van Rensburg.  

This initiative is also embedded in the university’s commitment to sustainability, as waterwise plants, artificial grass, and low maintenance finishes have been carefully selected to reduce the environmental footprint. “Artificial grass was used in combination with natural vegetation, which requires minimal water and maintenance,” he added.  

In addition to accessibility, sustainability plays a central role in the redevelopment. The project is designed to contribute to the university’s goal of reducing its carbon footprint by promoting pedestrian-friendly spaces and minimising the reliance on fossil-fuel-driven vehicles.  

Van Rensburg highlighted the efficiency gains in the management of green spaces, noting that the design will reduce the frequency of maintenance, which in turn reduces carbon emissions and energy consumption. “By promoting pedestrian circulation and integration with public transport, the use of vehicles using fossil fuels is minimised,” he said. Walking, he added, is not only a more environmentally friendly option, but also promotes the health and well-being of the campus community.  

Social spaces for collaboration  

The redevelopment introduces six new social nodes across the campus, each offering unique opportunities for student engagement and collaboration. “Smaller pockets have been created, which form part of the larger public space, resulting in a microclimate where people can relax and socialise,” Van Rensburg explained.  

The spaces are designed with flexibility in mind, featuring various seating arrangements, including spaces for meetings and group collaborations. Among the new additions is an amphitheatre, which provides a multifunctional space for lectures, performances, and other activities. “Flexible communal spaces were created for recreational opportunities, resulting in a balanced campus lifestyle,” Van Rensburg added.  

Recognising the increasing reliance on technology, the redevelopment also incorporates features such as charging stations and Wi-Fi connectivity. The spaces are envisioned as ‘information zones’, providing students and staff with convenient access to online resources while they relax or connect outdoors. “With Wi-Fi connectivity, the spaces function as an extension to traditional libraries,” noted Van Rensburg.   

While the Intsika Garden redevelopment is a significant step forward, plans are already underway for further infrastructure and green initiatives. “The soft landscaping and signage contracts were awarded for the Intsika Garden,” Van Rensburg confirmed. He also revealed that much-needed renovations to the front of the Intsika Building are in the pipeline, with a contractor soon to be appointed for the construction work. The planned upgrade will align with the garden’s aesthetics by drawing inspiration from indigenous art and culture, creating a cohesive identity for the campus. 

As these developments progress into 2025, the Qwaqwa Campus will continue to evolve, offering students and staff spaces that not only enhance their academic experience, but also contribute to a more sustainable and connected environment.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
