Nombulelo Shange, Lecturer in the Department of Sociology, asks what it would look like if we looked inward and invested in our own indigenous methods of nurturing and encouraging this and similar practices? Could other important scientific innovations emerge from it?

Opinion article by Nombulelo Shange, Lecturer in the Department of Sociology, University of the Free State.
Last year I wrote an opinion piece on the importance of indigenous knowledge, especially in healing practices. The piece detailed the origins of modern vaccines as an old, culturally appropriated African practice that was instrumental in fighting smallpox in 1700s Europe. That piece is perhaps even more significant this year, as many Africans are afraid of the COVID-19 vaccine. The hesitancy comes from a distrust of Western medicine, which has been responsible for many atrocities all over the world, as well as the South African biological warfare created by the apartheid government and led by Wouter Basson, who was dubbed ‘Dr Death’. 

African knowledge systems have come a long way – from being overlooked as valuable sciences or being misrepresented by Western scholars, who for a long time saw themselves as the only suitable custodians of our experiences, ideals, history, culture, and knowledge. Today, although a lot more needs to be done, we are seeing a rise in African intellectuals, practices, and solutions. In the academy, we see this in the calls for decolonised education, which has emphasised the importance of Southern African scholarly contributions locally and internationally. 

In our day-to-day lives, we also see this shift towards reclaiming African solutions to deal with modern-day challenges. Practices such as visiting sangomas/traditional healers and the general practising of African traditional religion were seen as taboo or often labelled as hedonism. Many were forced to acknowledge their ancestors or perform sacrifices in private. But today, many are openly practising their cultural rituals when they want to give thanks for good fortune, when they are struggling to find employment, and for both physical and emotional healing that individuals or the collective needs. Although not ‘scientifically verified’, the African herb called umhlonyane helped many during the COVID-19 pandemic, especially during the major waves that overwhelmed and threatened to cripple our healthcare system. Many have turned to this herb as a solution to help them fight COVID-19. Umhlonyane is commonly used by sangomas for a variety of reasons; to boost the immune system, for patients with illnesses that attack the respiratory system, and many other things. This kind of revitalisation and mainstreaming of indigenous knowledge systems and epistemological pedagogies can undo challenges such as vaccine hesitancy and general distrust of biomedicine, while elevating African knowledge.

The missing link

Despite these and many other positive strides that place African knowledge at the forefront, something is still missing, because we are still far from where we need to be as a continent. There are many things we can draw from to make sense of why the progress is slow. We could draw from the usual arguments around the missing, undervalued African Renaissance. We could also argue that while African ideals are gaining prominence, they are often only invoked as an ‘alternative’ or afterthought. Arguably, even with umhlonyane, it was only from desperation that people turned to it. All of these are valid, but I also what to argue that we are limited by a kind of epistemological slavery, where we use conflicting Western systems of knowledge production in producing African knowledge. We rely on Western methodologies for knowledge production, Western schooling systems for how we engage with and use the knowledge, and even Western systems for how we store and preserve the knowledge. 

Trapping African knowledge in Western epistemology

The April Cape Town fire, which has spread to the University of Cape Town and destroyed the African Studies library, is one illustration of the danger of trapping African knowledge in Western epistemological systems. Much of what was lost in the fire is work that will most likely be lost forever; it is possible that no other records of it exist elsewhere. The issue is that in Africa, knowledge is communally produced, shared, and owned. Western systems encourage the containment and individual ownership of knowledge. Traditionally, African knowledge is often shared in the sense that the process of producing and sharing this knowledge is done as a collective and is built into the day-to-day practices rather than being crafted as a separate experience in the way that mainstream Western education and research is done. 

Reimagining African epistemology 

There is an important method of passing down useful skills that you still find in African households even today. As kids, we often hated it, because it took us away from our games, watching TV, or general leisure time. As Zulus, we refer to it as ukuthunywa/thuma – the English translation of ‘running errands’ does not adequately represent what it means, but it will do. I want to argue that this practice has traditionally been an important epistemological tool for producing and sharing knowledge. As a child growing up in a family of farmers, for example, you are taught how to be a farmer through these ‘errands’. You might start off with small requests, such as having to watch while the grown-ups or older children perform certain tasks; as time goes on, you are expected to take on more and more responsibilities in the family trade or even in helping neighbours and other community members. Even when it came to storing and preserving knowledge, it was done in such a way that it was still easily accessible. It would be stored as rock art, songs and performances, everyday crafts, and practices. And contrary to Western beliefs that Africans never wrote or documented, for cultures such as the Egyptians and Ashanti, knowledge was even stored as written inscriptions. 

When we move away from ukuthunywa towards the more Western mainstream, some challenges arise. Students are almost exclusively taught in theoretical ways, separate from their everyday experiences, which makes it difficult to understand and value the knowledge and its place in society. Knowledge goes from being communally owned to being owned by an individual researcher or institution, which limits who has access to the information, who has the right to use it, and even limitations on how it can be used. At times, even the communities from which the knowledge originally came, are limited by copyright laws. I want to argue that if we had created African knowledge using African practices or possible methodologies such as ukuthnywa, the loss of the UCT African Studies section wouldn’t have felt so bad, because the knowledge would be actively existing in society and the ability to recreate and redocument it would feel within reach. 

The freeing of our indigenous knowledge systems requires that we shift from looking outwards for solutions. For example, instead of looking towards dangerous fossil fuel and expensive Western renewable energy solutions to address our ongoing energy crisis, why not look inward and invest in our own indigenous methods of creating cheaper, sustainable biogas using animal and food waste. Imagine if we did it in ways that empowers black rural women who are the custodians of this knowledge, so that while dealing with the energy issues, we simultaneously address poverty and environmental degradation. What would it look like if we continued to nurture and encourage this and similar practices? Could other important scientific innovations emerge from it? Could it grow to the level of informing global discourse? Could we finally be uhuru?

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
