Indigenous Oral traditions should be explored

Two researchers from the University of the Free State (UFS) aim with their research to examine the portrayal of environmental conservation in oral stories from indigenous South African cultures. They also hope to add the under-researched genres of oral cultures to mainstream inter-/cross-/multi-disciplinary inquiries on environmentalism, the climate crisis, conservation and indigenous knowledge systems.  

Dr Oliver Nyambi, Senior Lecturer in the Department of English, and Dr Patricks Voua Otomo, Senior Lecturer in the Department of Zoology and Entomology, interdisciplinary research project titled; Environmentalism in South African oral cultures: an indigenous knowledge system approach, started in 2017. The research is about indigenous South African oral culture as a potential knowledge system in which indigenous forms of environmental awareness is simultaneously circulated and archived.

Understanding oral folk stories

According to Dr Nyambi the research brings together the disciplines of cultural and environmental studies, inquiring into the relationship between indigenous knowledge mediated by oral culture, and environmental awareness. “Our main interest is how we can understand folk oral stories about humanity’s interactions with the environment as creating possibilities for knowing how traditional societies consciously thought about environmental conservation, preserving plant and animal species, and sustaining ecological balance,” says Dr Nyambi

The project has been on hold since 2018 as Dr Nyambi took up a two-and-a-half-year Alexander von Humboldt Fellowship in Germany. It will resume in earnest upon his return to South Africa at the end of February 2021. The duo’s first article on the “Zulu environmental imagination” has since received favorable peer reviews in the reputable journal African Studies Review published by Cambridge University Press.

The aim and impact of the research

Focusing on oral stories from the Zulu, Sotho and Tsonga traditions, the study seeks to understand what, in the stories as well as modes of their transmission, reflects certain consciousness, knowledge and histories of African indigenous environmentalism before the advent of Western forms of conservation. A key dimension to the project is the focus on how indigenous knowledge about the environment and its conservation was/is shared and consequently preserved through storytelling, explains Dr Nyambi.

“We envision our research to spotlight the potential but currently untapped utility of oral cultures in conservation. Our field work in rural KwaZulu-Natal revealed a rich tradition of environmental knowledge, environmental awareness and nature conservation which is mediated and transmitted through folk stories.

“However, traditional modes of storytelling have rapidly declined, mostly due to the pressures of modernity, the often uncritical reverent acceptance of conventional science and its knowledge systems, as well as the dwindling number of human repositories and tellers of indigenous stories. Our research will recommend a systematic approach to the preservation of these stories before they completely disappear,” says Dr Nyambi.

He continues: “Beyond the usual promotion of traditional storytelling as a mechanism of cultural preservation, we will recommend the archiving of the stories in written form, inclusion in school material as part of moral education, and modernisation for easy circulation through, for instance, animation.”

Receiving funding

The researchers successfully applied for funding which they mainly used for field work. The project involves travelling to rural communities where much of the oral stories and storytelling exist. They also use the money to purchase, where applicable, published stories for analysis.

“We wouldn't be able to do this vital study without funding so we feel that the grant is a crucial enabler of this process of seeking and indeed making knowledge of this rarely-talked-about topic with implications for how indigenous knowledge can be harnessed in ongoing attempts at arresting the climate crisis.”

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
