UFS launches Greener SA: planting the seeds of a sustainable future

The University of the Free State (UFS) launched Greener SA, a five-year initiative to plant 400 000 trees across South Africa, at the Paradys Experimental Farm on Friday 12 September 2025. Backed by the Mastercard Foundation through the TAGDev 2.0 programme and RUFORUM, the project brings together government, industry, students, and academics around a shared commitment to sustainability and food security. The launch was marked by the planting of the first 100 trees, a symbolic act that set the tone for the years ahead.

Prof Jan-Willem Swanepoel, Director of the Centre for Sustainable Agriculture, reminded the audience that the UFS is one of 12 African universities entrusted with a $100 million investment in agricultural transformation. “This project is not a hit-and-run – it’s about sustainability, inclusivity, and building value chains that empower farmers and entrepreneurs,” he said. He ended with a parable of a farmhand who could ‘sleep when the wind blows,’ urging everyone to be proactive in preparing for inevitable challenges.

Responsibility and partnerships

That call for responsibility was echoed by Elzabe Rockman, Free State MEC for Agriculture and Rural Development, who linked Greener SA to the presidential One Million Trees Programme. She cautioned that planting without accountability leads to wasted effort. “If we plant trees, we want to be sure someone takes responsibility for them,” she said, highlighting the need for fire-resistant species, fruit trees in community gardens, and natural borders to replace vulnerable fencing. Looking at the students from Kovsie ACT who joined the launch, she added: “Jobs are not going to fall from the sky. They will come from agriculture and the environment. Harnessing youth energy is the way forward.”

Industry also pledged its support. Representing Empact Group – the sponsor of the trees – Helena Prinsloo described tree planting as an investment in legacy. “At Empact Group, we believe that doing right by our community and our planet is not just a responsibility. It’s a value that defines who we are and how we lead,” she said. Quoting the proverb that societies grow great when people plant trees whose shade they will never sit in, she added: “Today we are sowing seeds of hope, resilience, and opportunities for generations to come.”

Science, vision, and practice

Prof Corli Witthuhn from the Faculty of Natural and Agricultural Sciences placed the launch in a global context, pointing to conflict, inequality, and climate change – and the sobering United Nations report showing that only 20% of the sustainability goals have been achieved. For her, the Greener SA project is a response to urgent global challenges. “We want our students to be globally work-ready,” she said. “That means beyond textbooks, and this farm represents exactly that. We don’t want to produce graduates with degrees, we want to produce graduates who can walk into a lab, into a policy meeting, into a business anywhere in the world and make an impact.”

Her message was supported by expert voices. Guest speaker Prof Ben du Toit from Stellenbosch University explained that agroforestry systems can simultaneously provide timber, food, biodiversity, and resilience. “Agroforestry is not planting trees over here and grazing over there – it’s about integration, so that benefits reinforce each other,” he said.

At the Paradys Experimental Farm, this integration is already underway. Johan Barnard, Farm Manager and Junior Lecturer, described how shaded tree pockets will improve grazing fields and protect water resources, while fruit trees planted in partnership with Kovsie ACT will contribute to student nutrition and new food value chains. “We’re capturing value chains and taking it to the next level so that our students have research opportunities and the farm delivers real outputs,” he explained.

The launch of Greener SA showed that tree planting is about much more than beautification. It is a collective commitment – to resilience in the face of global challenges, to science applied in practice, and to building partnerships that prepare the next generation to make an impact.

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.
