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.

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.

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.
