Prof Helena van Zyl

Prof Helena van Zyl, beloved, long-time academic and Head of the Business School at the University of the Free State (UFS), will retire at the end of June 2021 after arriving at the university more than 40 years ago and serving as Director of the Business School for 18 years. Prof Van Zyl has been a steady leader, not just in the Business School, but also for the vast array of students who made the UFS Business School their preferred choice. Starting out as a student assistant in the early ’80s in the then Department of Money and Banking, Prof Van Zyl progressed to become a junior lecturer in 1982, which placed her in a key position to eventually apply for Directorship of the Business School. 

The journey

“The university went through some very tough and equally delightful times; during the nineties, strict austerity measures were implemented. In 1987, the department received its first computer; one for the entire department. The internet was from a different planet. Some of the senior academics refused to use the internet and emails. All their letters and other communication were still typed by appointed typists. I saw many rectors, deans, colleagues come and go – each management era had its own challenges and opportunities.  In the end, it all worked out for the better,” says Prof Van Zyl.

“A highlight of my journey was the long road with my personal assistant, Alta Myburgh. I have known her since 1983 when she was a third-year student in my class, went on to become a student assistant, and with the exception of three years (if I remember correctly), she was next to me with loyalty that you will seldom find,” she explains. “When the Business School moved to its own address/building, it was certainly a highlight, but the ultimate was to contribute to students’ development and growth. For me, it has always been about the students and my staff,” says Prof Van Zyl. 

Invest in students and employees

Prof Van Zyl believes that success builds on integrity and that contributing to the development and growth of students and employees is integral to the success of any institution. “To add value to people’s lives is very rewarding.  One of the biggest lessons that I have learnt is that you need to empower the students and employees; invest in them, and they will invest in you. I am not convinced that we always got it right to manage our people correctly, but I guess this will remain an ongoing challenge,” she says. “I have learnt that if you create a platform of trust and belief in people, then they thrive,” explains Prof Van Zyl.

Looking forward

As Prof Van Zyl wraps up her journey at the UFS, she reflects on the past and what the future holds. “It was a privilege to work at the university, and I cannot extend enough gratefulness for all the opportunities I had. When I started working at the UFS, very few – if any – programmes were in place to assist new appointees with orientation, induction, etc., and you had to find your own way. I believe this has in a strange way contributed to one’s development and growth,” she says.

As for retirement, Prof Van Zyl is looking forward to travelling again, enjoy watching sport, gardening, and listening to classical music. “I will continue working part-time in the field of quality assurance, and also use this time to embrace new things. There is life after retirement,” she says.

Prof Van Zyl would like to be remembered for “sensitising people to seize the opportunities in life, and to make a difference – wherever you go, make a difference in your life and your work.”


Well wishes

Dr Liezel Massyn, Programme Director: BML Programme, UFS Business School

“Prof Helena embodies the Business School’s philosophy through the tagline, ‘Be worth more’. She challenges us to be worth more every day, in every aspect of our lives. She is a tough cookie. There are rules, and when you get to meet her, you learn very quickly that there is one way – the right way – to get things done. She asks tough questions and always strives to improve.  She taught us the unwritten rules of the academic world, the academic knowledge of her field (whether you want to hear it or not), and life skills to survive and thrive in challenging situations. She is always willing to walk a thousand miles with you and has a deep concern for her staff and students – always interested in everyone’s story and continuously investing in people. Prof, thank you for not only living – ‘Be worth more’ – but also inspiring the next generation to make it part of our values.”

Dr Johan Coetzee, Senior Lecturer, Department of Economics and Finance

“Prof Helena taught me from my second year of study in 1997 and was instrumental in my development as a scholar. She has set an example for so many people of a strong woman who gets things done, while at the same time showing such compassion that you are inspired. The UFS is losing one of the ‘legends’ of yesteryear. She will be impossible to replace.”

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.
