Dr Nomalungelo Ngubane, the Director: Academy for Multilingualism, is working through various initiatives to ensure that the UFS becomes and remains the South African leader in multilingualism.

The Academy for Multilingualism was established at the beginning of 2021, flowing from the UFS Language Policy (2016) that is currently under review, and which expresses the university’s commitment to multilingualism, with a particular emphasis on Sesotho, Afrikaans, and isiZulu, while English remains the primary medium of instruction for undergraduate and postgraduate studies.

The Student Language Preference Survey continues to indicate that many students have difficulty understanding English lectures due to language differences. Multilingual models from places like South America, India and South Africa were considered in order to structure the approach at the UFS.

Promoting indigenous languages

To mitigate the English barrier, the academy is developing multilingual academic glossaries. The multilingual glossaries are also intended to drive the promotion of indigenous languages (Sesotho/Afrikaans/IsiZulu) as academic languages, and to create multilingual learning spaces that embrace diverse languages.

Academic word lists from seven departments are in the process of being translated – in conjunction with the Unit of Lexicography – to create glossaries. The team at South African Sign Languages will add videos to these glossaries to provide unique and inclusive content in the realm of multilingualism. 

In 2022, the academy, in collaboration with the Library and Information Services, launched an African Languages Press with the aim of promoting and advancing publications of literature and research books using South African indigenous languages. 

The Academy for Multilingualism also promotes multilingualism through the Initiative for Creative African Narratives (iCAN), a programme that encourages students to write short stories in their indigenous home languages. By incorporating student narratives into learning material, students learn about one another, from one another.

The iCAN multilingual booklets are also used to encourage extensive reading among undergraduates and among learners in the surrounding community schools.

Use of translanguaging practices
 
The academy is also working with the Centre for Teaching and Learning’s (CTL) A_STEP programme to pilot the use of translanguaging practices in tutor sessions. UFS staff will also be trained on teaching and translanguaging practices. Voice-over translations of English lessons into Afrikaans and Sesotho in the Faculty of Theology and Religion paved the way for the academy to proceed with this practice in other subjects. The Translanguaging Seminar 2022, hosted by the academy and the CTL, was used as a platform for sharing translanguaging knowledge and practices by academics from the UFS and other institutions.

The Kovsies Multilingual Mokete has become a popular annual tradition celebrating different cultural expressions – in visual art, poetry, storytelling, drama, music, and song – by different language groups and in the different languages that are dominant at the UFS (i.e. English, Afrikaans, Sesotho, isiZulu, and Sign Language). This year’s event was held on the South Campus in October.

With its various initiatives, the Academy for Multilingualism will ensure that the UFS becomes and remains the South African leader in multilingualism.

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.
