Eunice Lebona
Eunice Lebona sees herself as a ‘perfectionist procrastinator.’

She is literally the beginning and the end of students’ academic careers on the Qwaqwa Campus, as she welcomes each one of them with an application form when they arrive and ensures that they enjoy their moment in the Rolihlahla Mandela Hall when they graduate. She says she derives all the pleasure and creativity from ‘last-minute crunch’. For those who have interacted with her, she epitomises excellence in the execution of her duties, but many would not know that she is a procrastinator. 

She is Eunice Lebona, Assistant Director: Student Academic Services.

Childhood lesson

‘Ausi Eunice’, as she is affectionately known, credits her grandmother for valuing accountability, her most prized childhood lesson.

“My grandmother raised me and as the oldest grandchild, I learnt the value of accountability at an early age; this has been the cornerstone of my life and career.  Although it is valuable to have support around you, standing on your own two feet is critical, because you will not know when that support might not be available,” she said. 

Working with students comes naturally to her, as she is inspired by progression and achievement.

Personal inspiration

“Getting to higher echelons than previous accomplishments, is my inspiration.  My successes are energisers to achieve the next steps on unique and distinctly different notes than the previous ones. It is this same notion that builds my view, that – as the University of the Free State – we need to see women representation in leadership on a greater scale, as well as respect for their spaces of delivery.”

When asked about the one thing that very few people knew about her, she said: 
“I am a procrastinator. In fact, I am a perfectionist procrastinator. Although procrastination is not good, the last-minute crunch is stimuli to ideas that I would normally not dream of in my comfort mode,” Lebona insists.

What is success?

She defines success as “inner gratification which is the result of the outcomes I had to deliver on”.  She adds: “Witnessing the success and motivation of others from the small contributions I have made in their lives, is all the success that resonates with me. Respect and humility go a long way in attaining success. As indicated earlier, my grandmother played a crucial role in my upbringing and instilled in me the philosophy entrenched in Luke 6:31 that says: ‘Do unto others as you would have them do unto you.’ That has been my motto since her passing away”.

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.
