New evidence provides a detailed picture of the extraordinary economic fallout from the COVID-19 pandemic. All regions lost about a fifth of their jobs between February-April, although the cities began to show signs of recovery with the easing of the lockdown to level 3. Half of all adults in rural areas were unemployed by June, compared with a third in the metros. So the crisis has amplified pre-existing disparities between cities and rural areas.

Prof Ivan Turok, National Research Foundation research professor at the University of the Free State (UFS) and distinguished research fellow at the Human Sciences Research Council (HSRC), and Dr Justin Visagie, a research specialist with the HSRC, analysed the impact of the crisis on different locations in a research report (Visagie & Turok 2020).

The main conclusion is that government responses need to be targeted more carefully to the distinctive challenges and opportunities of different places. A uniform, nationwide approach that treats places equally will not narrow (or even maintain) the gaps between them, just as the blanket lockdown reflex had adverse unintended consequences for jobs and livelihoods.

According to the authors, the crisis has also enlarged the chasm between suburbs, townships and informal settlements within cities. More than a third of all shack dwellers (36%) lost their jobs between February and April, compared with a quarter (24%) in the townships and one in seven (14%) in the suburbs. These effects are unprecedented.

Government grants have helped to ameliorate hardship in poor communities, but premature withdrawal of temporary relief schemes would be a serious setback for people who have come to rely on these resources following the collapse of jobs, such as unemployed men.

Before COVID-19

In February 2020, the proportion of adults in paid employment in the metros was 57%. In smaller cities and towns it was 46% and in rural areas 42%. This was a big gap, reflecting the relatively fragile local economies outside the large cities.
Similar differences existed within urban areas. The proportion of adults living in the suburbs who were in paid employment was 58%. In the townships it was 51% and in peri-urban areas it was 45%.

These employment disparities were partly offset by cash transfers to alleviate poverty among children and pensioners. Social grants were the main source of income for more than half of rural households and were also important in townships and informal settlements, although not to the same extent as in rural areas.  

Despite the social grants, households in rural areas were still far more likely to run out of money to buy food than in the cities.

How did the lockdown affect jobs?

The hard lockdown haemorrhaged jobs and incomes everywhere. However, the effects were worse in some places than in others. Shack dwellers were particularly vulnerable to the level 5 lockdown and restrictions on informal enterprise. This magnified pre-existing divides between suburbs, townships and informal settlements within cities.
There appears to have been a slight recovery in the suburbs between April-June, mostly as a result of furloughed workers being brought back onto the payroll. Few new jobs were created. Other areas showed less signs of bouncing back.

Overall, the economic crisis has hit poor urban communities much harder than the suburbs, resulting in a rate of unemployment in June of 42-43% in townships and informal settlements compared with 24% in the suburbs. The collapse poses a massive challenge for the recovery, and requires the government to mobilise resources from the whole of society.

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.
