UFS researchers, Dr Abraham R Matamanda, Senior Lecturer in the Department of Geography, and Prof Lochner Marais, Head of the UFS Centre for Development Support, collaborated with researchers in the UK and Brazil on a study on the impact of COVID-19 on children and young people. The study is part of the international PANEX-Youth research project.

Researchers from South Africa, the UK, and Brazil recently conducted a study on the impact of COVID-19 on children and young people, particularly those from disadvantaged households. Their research highlights that the pandemic has deepened existing inequalities, with children and young people’s voices and needs not being considered in policy decisions.

The study conducted by researchers from the University of the Free State (UFS) and the University of Fort Hare in South Africa; the University College London, the University of Birmingham, and Nottingham Trent University in the UK; and the University of São Paulo in Brazil, found that pandemic policy decisions largely ignored young people’s needs, resulting in long-term losses.

Educational inequalities

The report, titled International and National Overviews of the impact of COVID-19 on Education, Food and Play/Leisure and Related Adaptations, outlines how slow government action and policy gaps in efforts to stop the spread of COVID-19 have had a negative impact on children and young people’s health and welfare.

South Africa has been one of the countries hardest hit by COVID-19, and the study shows that due to social isolation and economic disruption caused by lockdowns, children and young people’s education has been stunted, their access to nutritious food has been reduced, and their ability to develop socially through play has been significantly restricted. The impact was worst for those living in disadvantaged poor households.

The study, which is part of the first stage of the PANEX-Youth research project, is divided into two volumes: the ‘Long Report’, highlighting the wider impact of the pandemic on children across the world, while the ‘Short Report’ drills down on the impact on three countries, namely the UK, South Africa, and Brazil.

Further insights from the study show that the digital divide has compounded educational inequalities as education has moved online during the pandemic, with households and regions with insufficient internet access falling behind. Collectively, and combined with the continuing cost-of-living crisis, the researchers believe that these disadvantages are likely to have detrimental consequences for children and young people in the short and long term, with many not yet visible.

Future pandemic planning

The team – which includes UFS researchers, Dr Abraham R Matamanda, Senior Lecturer in the Department of Geography, and Prof Lochner Marais, Head of the UFS Centre for Development Support – expects that policy gaps during the pandemic will negatively impact young people’s professional life trajectories, healthy lifestyles, mental well-being, educational opportunities, and self-confidence.

The team put together five recommendations to ensure that children’s well-being is incorporated into any future pandemic planning. These suggestions include:

  • The need to keep children and young people at the centre of pandemic preparedness efforts.
  • More priority and attention given to the hidden voices and experiences of young people, and particularly those from monetary poor households.
  • Greater recognition that schools play an important, central role as life and care hubs.
  • Greater recognition of play and leisure as rights that are fundamental to children and young people’s development.
  • More structured and systemic responses to multiple dimensions of risk from local and national responses are recommended, based on a rigorous assessment of what worked and failed during the pandemic.

Adapting in the post-pandemic period

Prof Lauren Andres, Professor of Planning and Urban Transformations at the University College London – also the lead author of the report – said: “COVID-19 exposed and exacerbated inequalities that already existed prior to the pandemic. Children and young people’s voices and needs were not heard and accounted for. Our research shows that because of policy gaps and slow government action during the pandemic, disadvantaged children and young people are now facing serious consequences that could be with them for a long time, both here in the UK and around the world.”

According to Dr Matamanda, “The COVID-19 pandemic showed the lack of understanding of what children and young people need in their daily lives. During the pandemic, the rights of children and young people, especially play/leisure, accessing adequate food and education, seemed to be overlooked or least prioritised. This was evident from the slow and inconsistent COVID-19 government policies and strategies that failed to acknowledge the networks and value chains through which children and young people are supported. In this way, our research shows the gaps and inequalities created and widened among children and young people in South Africa, especially those from disadvantaged households who have now been left behind and are grappling to adapt in the post-pandemic period.”

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.
