Government needs to see the private sector as a true partner, whose expertise and capital can leverage its plans

Opinion article by Prof Philippe Burger, Pro-Vice-Chancellor (Pro-VC): Poverty, Inequality and Economic Development, University of the Free State

Many South Africans watched in disbelief last week as KwaZulu-Natal and Gauteng descended into looting, chaos, and destruction after Jacob Zuma’s imprisonment. Though probably instigated by disgruntled pro-Zuma supporters, it is clear that the protests very quickly spun out of control.

In newspapers, the question was repeatedly asked: did we see the hungry poor looting for food, or the opportunistic middle-class turning up in cars and bakkies to grab big-screen TVs and fridges? While images and videos clearly show that the latter were present in large numbers, the sight of other people – including gogos – ransacking supermarkets and running off on foot with loaves of bread and bags of maize meal, point to the former. In short, if people had jobs and hope that their lives would improve, I doubt we would have seen such anarchy.

Only a matter of time before protests and unrest occurred

With official unemployment above 30% and the broad unemployment rate – which includes discouraged work-seekers – in excess of 40%, it was only a matter of time before protests and unrest occurred. Zuma’s imprisonment was surely incidental. If it hadn’t been that, something else would have triggered the chaos.

COVID-19 also aggravated the situation, with 1,4 million people losing their jobs as a result of lockdown measures. In addition, the R350 COVID-relief grant expired at the end of April, leaving many with less food on the table.

A number of people argue that, in light of what has happened, we should bring back the relief grant; government may not have much choice now, given the lingering effect of 16 months of COVID restrictions on levels of unemployment and poverty. It will simply have to rearrange its budget to do so. However, we can’t stop at grants.

Even though a grant puts a bit of food in your stomach, it does not give you hope that the future will look better than today. It’s that bleak-looking future, that sense of nothing to lose, that fuels the looting and gives unsavoury politicians leverage for their selfish interests. Contrast this behaviour with that of taxi drivers, who came out to protect malls and chase away looters. They did so because they have something to lose, a stake in the economy to protect.

Every South African has a stake in the economy

We need to ensure that every South African has a stake in the economy. That way, people will have a sense of belonging, they will have options and agency, and they will have resources to improve their lives. They will have hope that the future will look better than the present. A person with a stake in the system is unlikely to break that system. 

We therefore need to seriously reconsider our policies, speed up much-needed change, and start building a believable message of hope – hope stemming from real concern for the plight of the poor, and serious implementation of policy. To help the poor, we need to create jobs, and for that we need investment.

Analysis of economic data shows that for every percentage point rise in private investment as percentage of GDP, we lift GDP growth by a third of a percentage point. And, on average, for every percentage point that GDP grows, employment increases by 1%. In recent years, private investment has averaged a mere 12% of GDP. If we can lift it to 15%, or even to 18%, GDP can grow by an extra one or two percentage points. It might not sound much, but after a decade or two it makes a big difference.

However, for this to happen, the government will have to see the private sector as a true partner whose expertise and capital can leverage the state’s plans. With such an approach, for instance, it would not be necessary for government to own and run an airline – a private operator will fill the gap in the market with its own capital, saving government billions of rands. And the government could long ago have let the private sector play a key role in the generation of electricity, instead of resisting change and only belatedly agreeing to lift the cap on private generation capacity from 1 MW to 100 MW.

Build communities where people escape poverty and have hope

The type and location of investment is also important. Data from the Council for Scientific and Industrial Research shows that SA’s urban population will have increased to between 50 million and 52 million by 2035. This is an increase of 12 million to 14 million compared to 2018.

We must use the opportunity to build green industries. It will save money and build a better environment. In short, as a growth strategy, we need a green, urban-driven investment strategy that caters for SA’s burgeoning urban population.

That way, we can build communities where people have a stake in the economy, where they have jobs and businesses, escape poverty, and have hope that their future and that of their children will improve.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
