UFS to offer agricultural engineering, as well as Africa’s first postgraduate ecological engineering sciences degrees

For the first time, the University of the Free State (UFS) will be offering a full four-year engineering degree. From 2026, the Faculty of Natural and Agricultural Sciences will present the Bachelor of Engineering (BEng) in Agricultural and Biosystems Engineering, alongside new PhD and MSc degrees in Ecological and Nature-based Engineering Sciences – the first postgraduate qualifications of their kind on the African continent. Together, these programmes strengthen the university’s role in addressing some of the world’s most pressing and complex sustainability challenges.

Louis Lagrange, BEng Project Manager, describes the new undergraduate degree as a milestone for the university: “It will be the first full engineering degree presented by the UFS, and it directly targets the pressing water–food–energy nexus. It combines hard-core engineering and precision farming digital skills with the living world of biosystems to develop regenerative and environmentally sustainable food production systems.”

The BEng degree is endorsed by the Engineering Council of South Africa (ECSA) and approved by the South African Qualifications Authority (SAQA). It is designed to prepare students for the full agricultural engineering design process – from identifying and evaluating challenges, to designing, implementing, and testing sustainable solutions. Students will also be able to specialise through electives in animal production, horticulture, or open land crop production.

Lagrange explains that the programme offers students hands-on engagement from the start. “They will gain experience in agricultural mechanisations such as drones and GIS, water and irrigation systems, soil and environmental stewardship, renewable energy including solar and biofuels, precision agriculture, data-driven smart farming, and food processing.”

BEng graduates will be well positioned for diverse careers, ranging from agricultural/biosystems engineer, irrigation and water resource engineer, smart farming specialist, and food processing engineer to roles in mechanisation, soil conservation, animal husbandry, and energy conversion. Employers include agribusinesses, consulting engineers, environmental firms, government agencies, and research organisations.

According to Dr Jacques Maritz, Head of Engineering Sciences, “Our BSc, MSc, and PhD graduates will be uniquely positioned as ecological engineering scientists who can also branch out to advanced sustainability analysts, computational sustainability professionals, or nature-based complexity scientists who will have the future-proof skill of solving complex sustainability challenges in interdisciplinary teams by using some of the most advanced technology. On the horizon – an NQF 8 postgraduate diploma (PGDip) in Ecological and Nature-based Engineering Sciences to academically link undergraduate students to postgraduate studies.”

Postgraduate degrees: advancing ecological engineering

Alongside this undergraduate development and the existing BSc specialising in Physics with Engineering Subjects, the UFS is also introducing new postgraduate degrees in Ecological and Nature-based Engineering Sciences. “These are the first qualifications of their kind on the African continent and are endorsed by the International Ecological Engineering Society (IEES) and the Ecological Engineering Institute of Africa (EEIA),” explains Dr Maritz.

Dr Maritz explains: “Ecological engineering applies ecological and complexity science principles to design and restore sustainable ecosystems that integrate human society with the natural environment. These programmes will also strengthen work-integrated learning at the UFS, preparing graduates to address climate resilience, scientifically led biodiversity restoration, pollution remediation through data-driven interventions, and sustainable complex systems development.”

The postgraduate programmes are linked to the UFS’ growing research agenda, which includes plans for a biomass production facility at the UFS Industrial Park to advance scientific circular economy solutions, sustainable energy, and bio-inspired technologies. They also engage with cutting-edge fields such as extreme ecological engineering – creating new ecological functionality in severely degraded environments – and industrial ecological engineering, which reimagines the built environment through green construction materials, circular economy practices, and innovations such as 3D-printed green concrete.

Both Lagrange and Dr Maritz emphasise that these qualifications reflect the UFS’ Vision 130 commitment to being research-led, student-centred, and regionally engaged. They agree that the new programmes are ideally suited for students who want to combine engineering, science, and nature with emerging technologies, while pursuing careers that make a real impact on sustainability in South Africa and beyond.

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.
