The University of the Free State (UFS) Qwaqwa Campus is radiating with pride as Sociology master's student, Sanelisiwe Khumalo, has been elected to the prestigious African Union Student Parliament (AUSP). This achievement highlights the exceptional calibre of students nurtured within the institution, demonstrating their potential to effect significant change on a continental scale.

Khumalo's election is testament to her academic excellence, unwavering leadership, and profound dedication to student representation. As a student in the Department of Sociology, she has consistently displayed a keen understanding of complex social issues and a fervent passion for driving positive change.

The AUSP serves as a vital platform for student voices across Africa, providing a space for young leaders to engage in meaningful dialogue, advocate for student rights, and contribute to shaping higher education policies. Khumalo's presence in this esteemed body will undoubtedly bring invaluable perspectives, representing the interests of UFS students with distinction.

"Congratulations, Sanelisiwe Khumalo, on your remarkable achievement," remarked Divane Nzima, Senior Lecturer and Subject Head of the Department of Sociology in the Faculty of The Humanities. "Being elected to the African Union Student Parliament is an indication of your dedication to contributing towards positive social change. As a Sociology master’s student at the University of the Free State, you have made us immensely proud. We wish you strength and wisdom to inspire change across the continent."

Khumalo’s journey is a shining example of the transformative power of education and the boundless opportunities available to students on the UFS Qwaqwa Campus. Her success story embodies the university’s commitment to fostering a supportive and empowering environment where students can thrive and reach their full potential, aligning with the UFS’ Vision 130 as a student-centred institution focused on excellence and impact.

Adding to her impressive journey, Khumalo participated in an enriching exchange programme at the University of Education Freiburg in Germany last year. This collaboration, formalised through a Memorandum of Understanding (MoU), has opened doors for students, staff, and faculty members to engage in valuable academic and cultural exchanges.

Khumalo was an early beneficiary of this partnership and spent four months in Freiburg, immersing herself in the vibrant academic and cultural landscape. "The opportunity to study at the University of Education Freiburg was a dream come true," Khumalo shared. "The university's reputation for innovative teaching methods and its commitment to fostering a diverse and inclusive learning environment were incredibly appealing."

This experience, coupled with her dedication and leadership, has prepared her for the challenges and opportunities that lie ahead in the AUSP. Her journey serves as an inspiration to fellow students, demonstrating that with dedication, passion, and a commitment to excellence, they can achieve their dreams and contribute to shaping a better future.

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.
