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.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability
The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
