Enhancing students’ linguistic abilities
Language teaching professionals from Southern Africa attended a two-day symposium on foreign language acquisition practice on the UFS Bloemfontein Campus.

Language teaching professionals from across Southern Africa recently gathered at the University of the Free State (UFS) to discuss the need for benchmarking and standardising teaching and assessment practices. 

With the aim of empowering lecturers and researchers responsible for language acquisition and delivering competent students to ensure their employability globally, the educators addressed the challenges of language acquisition in the region. It was the first time that educators from different language disciplines, including Dutch, German, French, Afrikaans, isiZulu, Sesotho, and Sign Language, met to discuss standardisation and best practices in teaching and assessment.

The symposium, which was hosted on the Bloemfontein Campus on 8 and 9 June 2023, brought together educators from the UFS, North-West University, University of Cape Town, University of the Western Cape, University of KwaZulu-Natal, University of Pretoria, Rhodes University, University of South Africa, Stellenbosch University, University of the Witwatersrand, University of Limpopo, and Sol Plaatje University. They were joined by participants from the University of Namibia and the National University of Lesotho, providing a regional perspective. 

Standardising language acquisition in Southern Africa 

Prof Angelique van Niekerk, Head of the Department of Afrikaans and Dutch, German and French, says the meeting marked a movement towards delivering competent students in order to increase their employability in languages such as Dutch, German, French, Afrikaans, isiZulu, Sesotho, and Sign Language. 

“It is probably the first time that the different language disciplines and colleagues from disciplines involved in language acquisition in Southern Africa have met to discuss the need for benchmarking and standardising.” 

“The symposium was not on multilingualism per se, but as language scholars, we support multilingualism. Social cohesion is affected positively if people and their culture and language are accepted and thus used.”

Talking about the need for a reference framework for benchmarking languages, Dr Michelle Joubert, Subject Specialist in the UFS Centre for Teaching and Learning, told delegates in her keynote address that a coordinated system provides a basis for the mutual recognition of language qualifications. 

“Our aim is to develop a framework of standards for indigenous and foreign languages to reflect the political and social realities of a multilingual and multicultural South Africa, which aims to form a single South African education, employment, and residential space for its citizens.”

In another keynote address, Dr Carina Grobler, Subject Chair and Lecturer in French at the North-West University, highlighted effective assessment tools to enhance students’ ability to learn additional languages. 

Prof Van Niekerk says many new initiatives, such as the sharing of resources on centralised platforms, were some of the gains following the symposium; a follow-up event is planned for 2024.

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.
