Success is tied to the company you keep
Prof Brownhilder Neneh believes failure is part of success – it teaches you to be persistent and resilient.

As a young girl growing up in the Cameroon, her dad told her that once she had completed her first degree, she could choose where in the world she wanted to study. Her first choice was the United States; she applied and was admitted.

So, how did she come to complete her postgraduate studies and then became a professor and Head of the UFS Department of Business Management?


A matter of timing

Prof Brownhilder Neneh, Associate Professor in the Department of Business Management, tells the story. “It was a matter of timing. The new intake in the US took place in June; I started looking around and saw that there was an opportunity to come to the UFS. I did not want to waste six months; so, I came here, did my honours degree, and within one year and five months, I completed my master’s degree (Cum Laude), and then went home. I thought of doing my PhD in Germany but realised that the language might be a challenge; I came back and within a year and a few months, I completed my PhD.”

Listening to Prof Neneh relate the story, one might think she does nothing but study; although her academic workload is high, she finds the time to play with her 14-month-old baby every day. “When I arrive home and she sees me – that’s when my energy soars – and we start playing. Where possible, I take her to conferences with me. As a working mother, I understand the challenge of finding the balance, and my husband is great in supporting me.”


Finding the balance

Having risen to the position of professor, being happily married, and apparently having found the balance which many people seems to strive for their entire lives, I ask Prof Neneh what her recipe for success is. She doesn’t hesitate: “Success is tied to who you marry (if you get married), the company you keep, hard work, consistency, and always trying to be the best at what you do – and, oh yes, failure is part of success; it teaches you to be persistent and resilient. I also believe that God’s grace and favour has added to my success.” At a conference in September 2019, Prof Neneh once again talked about her favourite topic – women entrepreneurs and the challenges they face. She believes that there is a lot to be done to lessen the load of entrepreneurial women. And as I get ready to leave, I ask for her definition of success. She doesn’t hesitate: “Seeing students fly above you – and shining. Yes, to see them shine.”

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.
