Prof Thuli Madonsela persuades women to pursue their purpose
Discovering that she was “pretty” for her purpose gave Prof-Adv Thuli Madonsela’s life direction.

What does embracing womanhood mean? For Prof Thuli Madonsela it is about loving yourself and whatever you believe is your purpose in life. 

“All of us are designed for our purpose and are fit for our purpose, you should embrace that and make the best of it,” said South Africa’s former Public Protector in her keynote address to the Women’s Breakfast. In commemoration of Women’s Month, the University of the Free State (UFS)’s Employee Wellness Division hosted the annual event on 21 August 2018 where 900 women gathered under the theme: ‘Embrace your womanhood.’ 

Being a woman today


Law Professor and Law Trust Chair in Social Justice at Stellenbosch University, Prof Madonsela, urged the audience to look beyond the exterior and recognise “that we as individuals have a lot in common”. Speaking of unity in diversity, she praised some of the giants on whose shoulders modern women stand, such as Charlotte Maxeke, Olive Schreiner, Una Wookey, Albertina Sisulu, Winnie Madikizela-Mandela, Helen Joseph, Pam Golding, Bessie Head, and Ellen Khuzwayo.

These leaders are the epitome of following the purpose of “embracing everyone’s humanity and challenging things that diminish the humanity of others”, according to Prof Madonsela.

Remaining resilient and resolute 

Despite having to contend with a patriarchal system and face challenges such as gender-based violence, femicide, poverty, inequity, media stereotypes, as well as poverty, women continue to rise. Prof Madonsela called for women to capitalise on positives such as freedom and possessing a certain degree of power, legal equality, playing a role in political spaces, economic progress, and owning a public voice.

Drawing inspiration from her humble beginnings and the lessons learnt in leadership, Prof Madonsela conveyed a simple message to all women: “You are exactly as you should be. You are a perfect expression of your creator’s magnificence. You were created for a purpose and whatever you do, just step up and pursue your purpose.”

A word from an inspired woman

It was a memorable event for Burneline Kaars, Head of Employee Wellness. “This year it was an honour to host Prof Madonsela who could share both her academic background and professional experience. She accomplished this by skilfully incorporating lessons from our country’s history and her passion for justice,” she said.

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.
