A story of hope, courage, resilience, and working your way to the top. Dilahlwane Mohono started working as a cleaner at the UFS in 1992. Today, she is a Senior Faculty Officer in the Faculty of Natural and Agricultural Sciences and holds two honours degrees.

Fuelled by her deep pain due to falling pregnant during her matric year, as well as the desire to one day hold a qualification, Dilahlwane Mohono – Senior Faculty Officer in the Faculty of Natural and Agricultural Sciences – says her story is her favourite, as it is a story of hope, courage, resilience, and working your way to the top.

Because of her pregnancy, Mohono did not complete Grade 12 in 1990. She got married immediately thereafter. In 1992, she began working as a cleaner for a company that was insourced to provide meals on the University of the Free State Qwaqwa Campus. She says this experience often left her with mixed feelings, as it hurt to see her peers studying further, but this is also what ultimately motivated her to complete her matric. “Graduation ceremonies were the most painful events for me. This eventually pushed me to turn to ABET to complete my matric in 1994. From there, I was determined to start my academic journey, so I registered with Stanford Business College for a Secretariat and Computer Skills Diploma. It was a six-month course, but I graduated in the end. That graduation inspired me. It motivated me to study further. Juggling work and studying became challenging, because I was a young mother and wife, but I had to attend classes after work.”

The joy of education

In 2000, she registered for a Higher Diploma with Unisa, and at the same time took up a new position in the library on campus. At the time, it was still called the University of the North Qwaqwa Campus. She recalls this as the beginning of her upward trajectory in life. “The joy of education and seeing how far I have come made me realise how much potential I have, so in 2003 I registered for a BA Sociology and English degree at the UFS, and thereafter went on to do my BA Honours in Sociology.”

She took up a new position as Assistant Officer in the Faculty of Education. Wishing to be relevant to her new faculty, Mohono completed a Postgraduate Certificate in Education (PGCE), and thereafter a second honours degree in Curriculum Studies. “I felt like I was flowing. My colleagues helped me out and I wanted to ensure that I was the best in everything, because I did not want to disappoint them. What always encouraged me, were my children. I separated from my husband in 2003, so I found myself raising my kids single-handedly, and I needed to show them that we could all make it, and life would still go on.”

In 2018, the Faculty of Natural and Agricultural Sciences advertised a senior position. Mohono says she took a chance and applied because she wanted more growth. “I am now a Senior Faculty Officer. I was privileged to be afforded an opportunity to work for the university, so I always thought – how can I work in an academic higher learning environment and not use the opportunity to study and pursue an education.”

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?
It has to be my late mother. She was a very hardworking woman, but she passed on very early, in her early 40s. She worked in the same dining hall I started in, and a lot of the women I worked with then worked with her too. They took me under their wings and motivated me to continue chasing my dreams. Some were not even educated themselves, but they motivated me. I drew a lot of inspiration from them.

What advice would you give to the 15-year-old you?

She must take pride in being a woman, know who she is, and know that she must be brave and confident, and run with education as the key to her success. If it wasn’t for education, I shudder to think where I could’ve been. When I look back and see what I have achieved, being able to rise from all that while single-handedly raising my children, it makes me feel very strongly about myself. I am a very powerful woman.

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.
