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.”

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.
