Dr Sabeehah Vawda, a pathologist in virology and a Senior Lecturer in the Division of Virology at the UFS, is one of the University of the Free State’s champion women.

As South Africa commemorates Women’s Month during August, the UFS shines a spotlight on women who are making an impact on our three campuses on a daily basis.

Dr Sabeehah Vawda is one of these women – a medical doctor with a postgraduate degree in medical virology. Dr Vawda’s work involves overseeing diagnostic virology laboratory tests, providing virology-related advice to other healthcare workers and diagnostic laboratories in the Free State and Northern Cape, research, and teaching and training undergraduate and postgraduate medical students. 

“I like that I work in a clean and (mostly) very controlled environment. In addition, virology has an ever-evolving nature; there is always something totally new or revised about viruses and our knowledge thereof,” says Dr Vawda.

Originally from KZN, Dr Vawda studied and worked in quite a few provinces. She studied in Pretoria (Tuks), did her internship in Pietermaritzburg, community service in Kimberley, and postgrad studies in Bloemfontein, where she has (surprisingly) remained since completing her studies. “I am currently employed by the National Health Laboratory Service (NHLS) as a pathologist in virology and by the University of the Free State (UFS) as a Senior Lecturer in the Division of Virology.”

Dr Vawda talks about what inspires her, challenges she faced, and what makes a champion woman.  

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

My mum. She is a tremendous inspiration because she is always motivated, sees the ‘bright side’ of dreary matters, and encourages both my sister and myself to do the same. My dad tragically passed away when I was 18 and my mum very courageously took on her dual role, encouraged my sister and I to pursue our dreams, and with the Almighty’s mercy got us both through medical school. She is continuously encouraging us to strive for more, both in our careers and spiritually. My mum remains my ‘go-to-person’, and as a new mum myself, she continues to be my tower of strength as I experience this new phase of my life.

What are some of the challenges you’ve faced in your life that have made you a better woman?

My dad’s unexpected demise felt like the end of all our lives. At the time, I was completing my first year of BSc and was trying to get into medical school. A month later, I was accepted by the University of Pretoria to study medicine and had to make the arduous decision whether to leave home or not. Being an introverted, quiet person, moving provinces without any idea of how to fund my studies was quite a daunting challenge. 
With my mum’s encouragement and the mercy of the Almighty, I accepted the offer and eventually received a full bursary. Retrospectively, being ‘thrown in at the deep end’, moving provinces alone, prolonged periods away from my loved ones, living without the comforts I had been accustomed to, and having a restricted budget, forced me to become independent and essentially moulded me into the person I am today.

What advice would you give to the 15-year-old you?

Your life is probably not going to follow the plan you have envisioned, because trials and tribulations are all part of life’s experience, but with faith and determination, everything somehow eventually falls into place. Always remember that the Almighty never gives a burden too tall. Remain humble despite your achievements and continuously strive to become a better version of ‘you’.


What would you say makes you a champion woman [of the UFS]?

At the outset, I have to state that I actually don’t consider myself to be a ‘champion woman of the UFS’ (yet, LOL), and was genuinely surprised and humbled when asked to be part of the Women’s Day feature. 

So, what makes a champion woman in the academic setting? To me, it is someone who excels in her field of expertise, is willing to go the ‘extra mile’, and continues to perform well under stressful conditions. A professional person who is approachable and willing to assist her students/colleagues while remaining respectful to those above and beneath her.

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.
