Magdalena de Koker accepts a posthumous degree on behalf of her late son, Mervin Hershel van Wyk.

A grieving mother brought tears to the eyes of almost everyone present during a graduation ceremony at the University of the Free State (UFS) on Thursday 20 April, when she took to the stage to accept her late son’s posthumously awarded master’s degree.

The usually festive and jovial graduation spirit inside the Callie Human Centre at the University of the Free State’s Bloemfontein Campus turned sombre in a matter of seconds as Magdalena de Koker ascended the stage to receive her son Mervin Hershel van Wyk’s degree. The Faculty of Theology and Religion student had been on track to receive a Master of Theology degree with a specialisation in Church History and Polity, but passed away before his graduation ceremony. The posthumous degree awarding honoured Van Wyk’s memory and acknowledged his family’s support throughout his academic journey.

“My emotions are conflicted,” De Koker said. “I feel a sense of pride for my son’s accomplishments, and eagerly anticipated celebrating his graduation. However, the profound loss of my son has left me devastated. Instead of being a spectator, cheering him on from the audience, I now find myself standing in his place on stage, wearing unfamiliar shoes, unsure where the toe or heel lies.” 

His legacy lives on

Before closing the ceremony Professor Bonang Mohale, Chancellor of the UFS, said he cried because this degree had to be conferred posthumously. 

“This is sad, tragic, and regrettable,” Prof Mohale said. “We all pray and hope that our children will bury us. Mama, we pray that you get peace by acknowledging the current trauma and pain, so that there can be some acceptance in order to start the process of healing. And with that process of healing comes forgiveness. The wonderful thing about forgiveness is that it allows more healing. May the good Jehovah be with the family and the whole clan. When we pray, we say ‘Thy will be done’. Thank you, in the wake of your pain, for making the time to be with this greater family of Kovsies.” 

Dr Eugene Fortein, Senior Lecturer in Church History and Polity, said his late student was an inspiration to many. “He firmly believed that God cared about the suffering of the impoverished and oppressed, and that justice would be served to those often overlooked. These convictions fuelled his involvement in politics, unafraid to use his Christian beliefs to advocate for change through protests. His trial sermon last year from Amos 5 – ‘But let justice roll on like a river, righteousness like a never-failing stream’ – embodied his unwavering conviction that justice and righteousness were integral to his faith.” 

Van Wyk’s passing is huge a loss for his family, friends, and the UFS and South African academic communities. His dedication and commitment to his studies serve as an inspiration to all those who knew him. The UFS community mourns the loss of a talented student and scholar, but his legacy will continue to live on through his contributions to the field of theology.

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.
