“Each one should test their own actions. Then they can take pride in themselves alone, without comparing themselves to someone else,” Rolene Strauss quoted from Galatians 6:4.

“Are you allowing yourself to be measured by society’s version of the perfect woman? Is that woman called ‘Perfect’ stealing your self-confidence, your potential, your joy, and your life? Are you allowing that measuring tape to measure you and tell you you aren’t good enough? I believe that as women it is time to stand up and say: ‘No, Perfect – you can’t steal my self-confidence.’ ”These were the opening words of the University of the Free State (UFS) Women’s Breakfast guest speaker, Rolene Strauss.

The measuring tape called ‘Perfect’

Making reference to her personal experiences from being a little girl with big front teeth and skinny legs, to growing into a teenager and having her waist measured, and going on to becoming a beauty pageant contestant, a wife, and a mother. Strauss shared the many ways she has been subjected to society’s unattainable standards. “That measuring tape suffocated me. I realised that there has to be more to being a woman than constantly trying to be perfect.”

The Kovsie alumna, medical doctor, entrepreneur and title holder of both the 2014 Miss South Africa and Miss World competitions, spoke to 820 women on the Bloemfontein Campus on 22 August 2019.

On coming together to uplift each other

Strauss also stressed the importance of planting the seeds of confidence in one another. “The quality of yourself as a woman depends on the quality of the women around you,” she said.

Susan van Jaarsveld echoed Strauss’s sentiments. In her capacity as Senior Director of the Department of Human Resources, which is the official host of the UFS Women’s Breakfast, Van Jaarsveld extended a warm welcome to our guest speaker. Borrowing the words of the late American author, Harriet Beecher Stowe, she reiterated that “women are the real architects of society”.

Paying tribute to women of Kovsies

Some former Kovsies who were also celebrated included Gerda Steyn, winner of the 2019 Two Oceans and Comrades ultramarathons; Madam Justice Mahube Molemela, Judge President of the Free State Division of the High Court, Dr Susan Vosloo, South Africa’s first female heart surgeon; Karla Pretorius, player of the 2019 Netball World Cup, Caroline Grace Brüssow, one of South Africa’s top songstresses; and Crystal-Donna Roberts, award- winning actress.

Kovsies continue to walk in the footsteps of excellence to demonstrate respect for the thousands of women who marched to the Union Buildings in Pretoria on 9 August 1956. In the spirit of honouring women of the past, present, and future, Van Jaarsveld reminded all the guests that they were valuable, powerful, and deserved every chance and opportunity in the world to pursue and achieve their dreams.

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.
