Dr Shezree Tiel
Top student: Dr Shezree Tiel graduated top of her class and summa cum laude during the Faculty of Health Sciences graduation ceremony on Friday.

As she achieved the goals she had set for herself, Dr Shezree Tiel, one of the latest graduates from the University of the Free State (UFS) Faculty of Health Sciences (FoHS), developed the courage to not only define her goals, but aim for even more. This is the reason she graduated not only summa cum laude, but as the top student in her year group.

Dr Tiel was one of 459 students who graduated on Friday (8 December 2023) during the FoHS’s December graduation ceremony. She graduated with a MBChB degree and is one of eight students to do so summa cum laude. During her five years of studies to become a medical doctor, she was the top student in each of her year groups.  

“I feel very excited and still in disbelief, because it has been my dream since first year to graduate cum laude, but there were moments I felt I may have to accept that it may not be possible. So, I am very delighted that despite all the challenges I faced, my dream was realised,” she said.

According to her, she decided to study at UFS as it is the only university in South Africa that offered a five-year medical degree.

Building healthier and happier communities

Talking about how she achieved this, Dr Tiel, who will be doing her community service year in her home province of Mpumalanga, said what was consistent throughout her years of study, was the need to avoid a uniform approach to studying. Instead, she continued, she embraced different ways to learn.

Said Dr Tiel: “I embraced different ways to acquire knowledge and used these to identify a method of study that would be best suited for each module, chapter and sometimes each day. Everyday courage, resilience, patience, and perseverance played a vital role in accomplishing all my achievements. In spite of all of this, I will always attribute my achievements to my trust in Christ.”

Her desire to make the best possible use of every opportunity she gets to gain knowledge and the hope to use that knowledge to be useful to people and communities, motivated her on her journey to become a doctor. She decided to study medicine because she aspired to work with people in the pursuit of building healthier and happier communities. She believed that medicine would provide a great foundation and platform to accomplish this.

Though she is yet to decide in which field she would like to specialise one day, she believes it would be in internal medicine because it has always been one of her favourite rotations. “I do hope whichever one I go into will provide me with an opportunity to teach because that is one of the things I delight in.”

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.
