Dr Jan Swanepoel believes that the agricultural sector must be assisted in every possible way to shift its focus from mere subsistence farming, as is still the case in many parts of the world, to sustaining the lives of millions of people on the planet.

17 October is marked as International Day for the Eradication of Poverty by the United Nations (UN). 

The University of the Free State (UFS) is involved in several initiatives aimed at empowering communities to create a sustainable livelihood for themselves in the long run.

One of these initiatives includes a project to build competitiveness for communal farmers by developing the wool value chain in the Free State. 

The UFS Centre for Sustainable Agriculture, Rural Development and Extension (CENSARDE) submitted a proposal to the Regional Universities Forum for Capacity Building in Agriculture (RUFORUM); their proposal was selected, and they were awarded a grant of US$300 000. 

Dr Jan Swanepoel, Senior Lecturer and Researcher at CENSARDE, says the world is moving from local and national markets towards a global system of trading. This means that neighbouring farmers working on small plots of land may be competing with large industrial farmers from another country in a single marketplace.

A drive to commercialise

He adds that in developing countries, there is increasing pressure on farmers to commercialise their operations. “In order to meet the drive for greater commercialisation, new skills must be developed to support farmers in becoming better entrepreneurs. Assistance towards infrastructure must be provided; and the needs of farmers, such as market access, must be identified and catered for.”

Dr Swanepoel points out that the agricultural sector must be assisted in every possible way to shift its focus from mere subsistence farming, as is still the case in many parts of the world, to sustaining the livelihoods of millions of people on the planet. 

“As the agricultural sector starts to realise this more fundamental role and responsibilities with regard to production, new strategies can be conceived towards the enhancement of the socio-economic status of all role players in the agricultural sector,” he says.

One of the industries that agriculture in South Africa can expand on, is the wool industry. 

“China is the biggest buyer of South African wool. During lockdown, no wool from South Africa was exported to China, causing the price of wool to drop significantly. Fortunately, the markets have opened up, the excess wool from Australia has been absorbed, and China is buying wool at full capacity now. Even though the price of wool is 30% below the price of last year, the markets are reacting positively, showing a steady increase. Wool buyers believe that this trend will continue due to international market demand exceeding the supply,” says Dr Swanepoel.

He also believes the creation of niche products from the wool will add to the existing value chain, creating more jobs and an opportunity for enlarging the export market.

Profitable and sustainable venture

CENCARDE is involved in an attempt to transform communal woolgrowers’ production from an underachieving enterprise to a profitable, sustainable, and renewable venture to enhance the livelihoods of communal wool producers. 

“In addition, with the extension of the value chain directly to consumers, job creation and development plays a vital role in supporting the South African National Treasury’s strategy,” adds Dr Swanepoel.

This project is thus built around the commercialisation of wool production in the communal areas of the Free State, by developing strategies to be implemented concurrently in order to attempt to manage the various challenges faced by these growers. 

As part of this project, a centralised infrastructure hub will be established on the UFS experimental farm to support wool production and processing. Woolgrowers, sheepshearers, and men and women from the community will also be equipped with the necessary skills and knowledge to operate in the wool industry. Adding to these skills, members of the community will be taught entrepreneurial skills in different aspects of wool processing, such as knitting, making felt products, spinning, and weaving. 

Another helpful aspect of this project is linking the communal woolgrowers to markets, and in so doing, giving them a collaborative advantage.

Educational benefits

However, not only communal woolgrowers will benefit from this programme. It also has educational benefits, as the project is designed to incorporate research. According to Dr Swanepoel, CENSARDE is very committed and are using this project as a pilot to demonstrate the potential for a more multidisciplinary, multi-stakeholder approach to education, research, and development. Fifteen students will directly benefit from this project, including two PhD and three master’s students.

Also adding value to the project is the development of private partnerships in the form of the Dohne Merino Breed Society, commercial farmers, and other key wool marketing agencies – which will assist with technical matters and knowledge – as well as the Free State Department of Agriculture.

All participants strive for more profitable and competitive communal woolgrowers in a changing global wool market. The project is not another educational exercise but will equip woolgrowers to change their circumstances for the better.

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.
