René and Richann as Reën.

In the same week, a lecturer at the University of the Free State graduated with a master’s degree in Political Science and topped the charts with her first single as part of the duo, Reën. Within the first week of its release, Vrystaat Vlaktes was the number one hit on iTunes, got more than 300 000 views, and the duo’s Instagram boasts more than 10 000 followers. Not bad for the shy – as she describes herself – René de Klerk. 

An interesting start 

After living in Canada for about four years, René’s family moved back to Bloemfontein where she completed the last three years of high school. She decided to return to Canada after matric for a gap year, which “turned out to be nothing like that at all!” she says. Life was much harder on her own without the protection and support of her family. “Eventually I got a job, and part of my duties were to clean the restrooms – seriously. That is where I started.” 

After applying for dozens of scholarships, René eventually got a bursary to study abroad. “I’ve always wanted to help people in some way – I really want everyone to be OK, to at least have their basic needs met.” She enrolled for a degree in International Studies, which she later completed at the UFS as a BA majoring in Political Science and Communication. Her academic potential did not go unnoticed, and she pursued further studies in Political Sciences while working and lecturing in the department.

A twist in the tale 

René met her partner, Richann Brüssow, during the reality show, Boer Soek ‘n Vrou. “Since I am shy by nature, being so exposed was unnerving, but then again, I got so much out of it.” The two hit it off as a couple, and their shared love for music soon turned into much more than either of them foresaw. “We were honestly just having fun,” René recalls, “and then a production company contacted us!” 

Initially, they thought of becoming wedding singers as a hobby, but Select Music found out about their endeavour and offered them an artist development deal. “I’m astonished,” René says, “my music background included school and university choirs. I never even considered becoming a performing artist. But then I met Richann …”

More to come

This is just the beginning of the road for René and for Reën. René will continue to leave a positive footprint wherever she goes, and Reën is soon to release their second single. “I will always be working in the field of Political Sciences and spend time in the music scene as a bonus,” she concludes.

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.
