Human Settlements Conference
Attending the first National Student Conference for Human Settlement students were, from the left: Dr Anita Venter, Lecturer in the Centre for Development Support; Phelani Mkhize, master’s student in Urban and Regional Planning; Prof Maléne Campbell, Head of the Department of Urban and Regional Planning at the UFS; and Nhlakampho Mahlalela, also a master’s student in Urban and Regional Planning.

“This invitation by the University of the Free State (UFS) comes at a critical moment when we begin to roll up our sleeves in an attempt to transform the lives of our people, and in efforts to modernise our cities and towns to attain sustainable livelihoods.” This was the words of the MEC for Public Works, Infrastructure and Human Settlements, Tshidi Koloi, on attending the first National Student Conference for Human Settlement. 

“The urban population of the world has grown rapidly – from 751 million in 1950 to 8 billion in 2018. How do we plan for rapid urbanisation?” Koloi asked. 

“We turn to the academic world for continuous research in various fields related to the development of human settlements. The role of the university and of this department cannot be overestimated. Clearly, we need to forge partnerships where our department can benefit from ongoing research towards the improvement of its value chain and programmes. In return, government could offer bursaries and internship opportunities for students.”

Integrate communities

More than 130 students from the Nelson Mandela University, the UUniversity of KwaZulu-Natal, the University of the Witwatersrand, and the UFS attended the conference to gain a better understanding of the challenges, policies, and practices of human settlements. The conference also allowed students the opportunity to not only engage with key members of government, but also with each other and delegates from the private sector.

Head of the Department of Human Settlements, Tim Mokhesi, said his department’s objective with housing for the future is to integrate communities; not to separate them because they are poor. If we separate communities, our next struggle will be a class struggle. 

“South Africa is in a crisis in terms of human settlement. In the past years, there was an exponential growth in informal settlements – 300 to 3 000 (with 143 in the Free State); the housing budget shrank, and local authorities do not have the capacity to deal with informal settlements. Can the few of us make a sufficient and significant contribution? Seeing your commitment as students is what gives us hope for a better future for all,” Thomas Stewart, Lecturer in the UFS Department of Urban and Regional Planning, said.

Innovative and inclusive re-housing

Students experienced two fieldtrips, one to the Hillside View Development Project, where the focus was on mixed housing. This project is part of the Mangaung Metro Municipality’s five-year integrated human settlements plan. According to developer Freddie Kenney, the project needs to be a development model for South Africa to change the picture of social housing. 

The second site visited was the Innovative Housing Building Project: Qala Phelang Tala, where peo-ple are trained to build their own houses. “It is a very easy process,” said Dr Anita Venter, Lecturer in the Centre for Development Support, who is lecturing Human Settlements Theory in the Department of Urban and Regional Planning. Since 2013, she was involved in the building of five houses. 

The latest building project at the Meraka Cultural Village in Roodewal, outside Bloemfontein, is a stu-dent-led project where they learn to develop a basic shelter suitable for survival in a future, post-natural, and climate-crisis world that will become between 2 and 4 degrees Celsius warmer within the next century. “It is important for people to build in climate-friendly ways,” Dr Venter said. 

She continues: “The project seeks to also renew, restore, and revitalise communities.” Sebabatso Mofama, who now helps with training, built this house similar to the one where she comes from in the Eastern Cape. “It is where I feel at home,” she said. 

The human aspect 

Dean of Student Affairs,Pura Mgolombane, touched on the human aspect of human settlements. “We first need to see the human in human settlements. ‘Yebo’, meaning I see you. See the human and develop quality houses.”

The event coincided with the launch of the new Bachelor of Spatial Planning Honours with specialisation in Human Settlements. The first two students graduated in April this year.

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.
