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?

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
