A Master of Commerce degree with specialisation in Industrial Psychology will be conferred on Kgalalelo Motlhabane, a graduate and funding officer at the Postgraduate School at UFS on Friday 9 October 2020 in a virtual graduation.

One of the success stories of this year’s virtual graduation is Kgalalelo Motlhabane, a graduate and funding officer at the Postgraduate School, University of the Free State (UFS), who was presented with an award from the National Research Foundation as the best designated authority for 2019.

Motlhabane, who lost her mother when she was in high school, didn’t just have to overcome poverty on her way to her first qualification, but also the fear of ending up on the street. On Friday 9 October she received a Master of Commerce degree with specialisation in Industrial Psychology.

A lot of challenges

“I had a lot of challenges during my first-year undergraduate studies. I could not afford textbooks and stationery. I spent most of my time in the library studying. More often I would be without food and proper clothes to wear.

“I would get warnings from my landlord when the rent was late. Sometimes I would find my room locked and my personal stuff removed. Not being able to pay outstanding fees restricted me from receiving my final results at the end of semesters and exacerbated the situation,” says Motlhabane.

Regardless of all these challenges, she was determined to not give up and return home to the impoverished community of Itireleng village near Pampierstad in the Northern Cape.

Overcoming the challenges

It was actually the distress, poverty and the difficult situation at home, together with her daily struggles that kept her focused. Through hard work, she managed to receive funding from NSFAS for her second and third years and despite the hardships, she obtained her BSocSci degree with distinction at the end of 2012.

“I was then selected to enroll for an Honours degree in Industrial Psychology in 2013. Without any funding prospects for my studies, I wrote to the former university rector Prof Jonathan Jansen, seeking financial assistance.

“Prof Jansen was very impressed with my exceptional academic performance and offered to pay my fees. He also offered me a position to work as a student assistant. I worked for three hours every day before going to the library to do my assignments and prepare for classes, presentations, tests and exams. I completed my Honours degree in 2013.”

In 2014, Motlhabane was employed as an intern at the UFS Human Resources Department and also enrolled for a postgraduate diploma in gender studies, which she obtained at the end of that year. The following year she joined the postgraduate school and started with her Master’s degree in late 2016.

Obtaining a Master’s degree

This was no easy task as she was employed full time which left her with little time to work thoroughly on her thesis, her limited knowledge about research, work pressures and demands, rejections, lack of support, discouragements, accidents and the inability to cope also played a role.  

“I would like to thank God for the strength he gave me to cope throughout my journey, my family for their prayers and continued support, as well as Prof Jonathan Jansen, Prof Petrus Nel and Prof Ebben van Zyl for their kind support and contribution towards my studies. Indeed, the future belongs to those who believe in the beauty of their dreams,” says Motlhabane.

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.
