Leading a happy and productive workplace - Susan van Jaarsveld

Susan van Jaarsveld is the Senior Director: Human Resources at the University of the Free State. Since the HR department is the ‘go-to person’ for all employee-related matters, her duties involve managing activities such as recruitment and selection, employee relations, performance management, training and development, and talent management. “As the employees are the most important asset, we have to ensure a happy and productive workplace,” she explains. 

What is the best thing about your job?
You always move between what is good for the UFS and what is good for the employees, and you have to build that bridge and find a good balance. The best part is that you can really make a difference – for an employee or a team – by helping them to let their (hidden) talents come to life and helping them realise their dreams.

What is the best and worst decision you have ever made?
Two of the best decisions I ever made were to have my two amazing children. They have enriched my life and I cannot imagine a world without them in it. I made many bad decisions, but I choose not to dwell on those. In hindsight, many of these bad decisions taught me valuable life lessons and also led me to wonderful new opportunities.

What was/is the biggest challenge of your career?
The biggest challenge throughout my career was to balance my work and home life. This is certainly a challenge that many people, especially women, can relate to. It means constantly feeling guilty. When I was at work, I felt guilty that I’m missing out on important parts of my children’s lives, and I felt guilty when I was spending time with my family and not working. My children are both grown-up now and maintaining a balance between my home and work life has become easier.

What does the word woman mean to you?
Being a woman is complicated, multi-faceted, and often unfair. Womanhood is about strength, love, and compassion; a human being who can be powerful and assertive and kind at the same time.

Which woman inspires you, and why?
I am inspired by South African women, the single mothers who raise their children in difficult circumstances, the ones who make ends meet every day, the CEOs who manage big companies successfully, the ones who are battered and bruised by life and other people but still keep going, the health workers who are carrying us through this COVID-19 pandemic, the ones who stand up against injustice and say, ‘when you strike a woman, you strike a rock’.

What advice would you give to the 15-year-old you?
You are enough! Relax and enjoy life to the fullest.

What is the one self-care thing that you do? 
I exercise regularly, it helps me to stay healthy in body and mind.

What makes you a woman of quality, impact, and care?
I choose to be positive, fair, and caring in everything I do. It is a privilege to be part of the UFS, where I strive to continuously improve the institutional culture, together with a very supporting and competent team. Care (commitment, attraction, retention, excellence) is the acronym that best describes the vision of the HR team; we care and incorporate this into every initiative we undertake.

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.
