Buhle Hlatshwayo has been selected for the 2023 Fulbright Foreign Language Teaching Assistant (FLTA) Programme.

Buhle Hlatshwayo, a master’s student on the UFS Qwaqwa Campus, has been selected for the 2023 Fulbright Foreign Language Teaching Assistant (FLTA) programme. Despite initially doubting herself, she took a leap of faith and applied for the programme, which turned out to be a successful decision. The Fulbright Programme is a prestigious scholarship programme that provides opportunities for international educational exchanges. The programme’s overarching aim is to enhance intercultural relations across more than 160 countries.

Hlatshwayo will be teaching isiZulu at the University of Georgia in Athens, Georgia, for an academic year. She leaves South Africa at the end of July.

Hlatshwayo is currently pursuing her Master of Arts with specialisation in English on the UFS Qwaqwa Campus, where she also completed her undergraduate and honours degrees in the same field. Her research focuses on East African Arab migration narratives to the Global North, with a focus on exploring the legacies of colonialism. She is also a learning facilitator in the same department.

A prestigious opportunity 

A friend and colleague, Mxolisi Mabaso, encouraged her to apply, knowing her desire to explore opportunities abroad. 

“I am still in awe of how this opportunity came about, especially because someone else saw potential in me while I didn’t believe in myself. My good friend pushed me to apply, because he knew I always wanted the opportunity to go abroad. I am thrilled and honoured to be part of this prestigious programme. I am looking forward to experiencing the US culture and ways of being.”

On her love for English, Hlatshwayo said she has always been fond of the subject but never considered it as a potential career path. After completing her undergraduate degree, Dr Kudzayi Ngara, a Senior Lecturer in the Department of English on the Qwaqwa Campus, encouraged her to pursue an honour’s degree in English, which ultimately shaped her academic journey.

Professional and personal growth awaits

While in the US, Hlatshwayo said she is looking forward to immersing herself in American culture and pursuing courses in American studies. She aims to learn more about diverse cultural backgrounds and share her South African heritage and cultural values with the international community. She said this exchange of experiences and ideas will broaden her horizons and contribute to her academic and professional development.

“The opportunities would not present themselves if you were not capable. If you know your goals, seize any opportunity that will enable you to get there. I was not granted this opportunity because I’m smarter than everyone else, but because of how I articulated my genuine motivations with future goals and how the Fulbright programme will help me achieve them,” 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.
