UFS Green Campus Initiative Team
The UFS Green Campus Initiative team after being announced winners for the fourth consecutive year.

The University of the Free State (UFS) is celebrating an outstanding achievement at the 12th Annual Green Campuses Conference (GCC) 2025, where its dynamic Green Campus Initiative (GCI) team from the Qwaqwa Campus clinched the coveted Best Exhibition Award. This marks an unprecedented fourth consecutive year that the UFS has secured this prestigious accolade, highlighting its unwavering commitment to sustainability and innovation within the higher education landscape.

Hosted by Nelson Mandela University in Gqeberha, Eastern Cape, the conference was presented by the Association of College and University Housing Officers - International (ACUHO-I) under the profoundly relevant theme, Ubuntu and Environment: African Indigenous Knowledge in Sustainability. Endorsed by the Department of Higher Education and Training, the GCC serves as a pivotal platform for institutions of higher learning across South Africa to exchange vital knowledge, share best practices, and explore groundbreaking innovations in environmental sustainability and climate change mitigation.

The UFS GCI team's exhibition captivated judges and attendees alike with its exceptional creativity, innovative spirit, and profound dedication to envisioning a greener future. "The creativity, innovation, and commitment to sustainability shone through every detail of the display," remarked residential head Itumeleng Lebusho, "a true reflection of what it means to envision a greener future".

The five students who represented the institution were Amukelani Ngobeni, Minenhle Mnguni, Sinenhlanhla Mathabela, Charmaine Nokubonga Nkosi, and Thandolwethu Nyathikazi.

A cornerstone of the student-driven conference, the GCC featured three main categories: project presentations, a runway showcase, and the highly anticipated exhibition. UFS students excelled across the board, demonstrating their ingenuity in tackling real-world campus challenges with sustainable solutions.

A particularly notable project was the student-designed mobile trolley. Addressing a common predicament faced by students transporting groceries from the main gate to their residences due to campus restrictions on taxis for security reasons, the team engineered an innovative solution. This solar-powered mobile trolley, equipped with batteries and a motor, began as a prototype in 2024 and has since evolved into a testament to student-led problem-solving. While the current iteration requires a Code 8 driver's licence to operate, its potential to revolutionise campus mobility is clear.

The conference's annual theme encourages participants to devise sustainable solutions to problems faced on campus, a challenge that the UFS GCI team has embraced with remarkable success.

The UFS' consistent triumph at the GCC is a testament to the dedication and sacrifice of its students, whose forward-thinking ideas continue to push the boundaries of what is possible in campus greening. "The students worked in a way that we never imagined," expressed Desiree Motsele, Residence Head within Housing and Residence Affairs. "The ideas that they come up with are truly inspiring."

By actively participating in this significant event, the UFS is not only strengthening its commitment to creating a green campus but also fostering a healthy learning and living environment. This continued dedication prioritises sustainability, advances energy efficiency, champions resource conservation, and promotes environmental stewardship, solidifying the UFS' position as a leader in sustainable practices within South African higher education.

The Director: Student Affairs, Zoleka Dotwana, said she would like to congratulate the students on yet another gold they won at the GCI 2025. “The effort, the hard work, the commitment you have shown, has once again raised our UFS flag high. I hope the experience and the graduate attributes you have learnt in preparing your project will go a long way in providing you with great opportunities when you leave our shores. It has been an awesome journey over the four years, one that we hold dear and that will remain in the history books of our campus. Thank you for flying our flag high - Only a Kovsie knows the feeling!' said an ecstatic Dotwana.

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.
