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.

To tan or not to tan: a burning issue

2009-12-08

Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
