Qwaqwa Campus Open Day
Colourful learners from near and far descended on the Qwaqwa Campus for this year’s Open Day.

The 2019 University of the Free State Open Day on the Qwaqwa Campus was a colourful affair, attended by learners from high schools in and around Qwaqwa. Leaners were treated to information tables that saw a display of activities, highlighting the multifaceted nature of the campus, dubbed ‘the education hub in the mountains’. The first session began with an excited crowd of mainly Grade 12s receiving words of encouragement from the Campus Principal, Dr Martin Mandew, who extended a word of welcome and gratitude to the teachers for responding to their call. He also encouraged learners to apply as early as possible for the 2020 academic year, as space in tertiary institutions is limited.
 
“Your future is here; Qwaqwa Campus is the place to be,” he reassured the learners. He concluded by saying, “Ours is a smart campus, well-resourced with information and communication technology facilities, among many other features”. 

Learners explore campus

In the second session, learners explored the campus to learn more about what is being offered. They were met by warm and welcoming smiles from representatives of all the faculties and departments. Support services sharing information with potential students included Housing and Residence Affairs, the Student Representative Council (SRC), Student Life, and KovsieSport. Pretty Nzong, a learner from the Seotlong Agricultural and Hotel School, said she has learnt a lot, especially from the faculties, as she did not know what she wanted to study next year. “My highlight of the day was the inspiration I drew from the Assistant Deans and Campus Management in their academic regalia. I hope one day I will ascend that very stage as a graduate,” she said. Her friend, Lebohang Motsoeneng, said the experience gave her a sense of direction on the career path she wants to follow, and this experience re-ignited her spark to become a natural scientist.

Student Life

Although academy was the centre of attention on the day, learners also experienced ‘the feeling’ said to be only known by Kovsies, as they indulged in the essence of student life, including sports, student leadership, counselling services, and career guidance.
 
A sports fanatic, Moleleki Motaung from Mmathabo Secondary School, alluded to his experience as ‘exciting’. “I have been struggling to get exposure, and I believe this campus will afford me an opportunity to showcase my talent on the football field.”  Kamohelo Pholohang, also from Mmathabo Secondary, said the experience was enlightening, as it dealt with his indecisiveness on the course of study that he wants to pursue next year. Both learners emphasised that they are definitely coming to study here next year; both will be studying for a Bachelor of Education degree, with the former reiterating that he will also be the campus football star!

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.
