Multilingualism is a buzzword at many South African universities. These universities promote social cohesion, a sense of belonging, and epistemic access and success by improving and advancing existing language policies and practices.

On 16 September 2022, the University of the Free State (UFS) had its first student discussion on the Bloemfontein Campus regarding the draft Language Policy, which is being reviewed for an updated version in 2023. With English being the primary language of teaching and learning, this policy aims to promote diversity in teaching and learning in Sesotho, isiZulu, Afrikaans, and Sign Language through translating tutorials and academic vocabulary and continuously establishing and maintaining trans-institutional, interinstitutional, and intra-institutional collaborations for the development of a translanguaging culture.

During the presentation, Dr Nomalungelo Ngubane, Director of the Academy for Multilingualism, revealed to students that the United Nations Educational, Scientific and Cultural Organisation (UNESCO) has designated a decade – from 2022 to 2032 – as the International Decade of Indigenous Languages. This guarantees that these languages are promoted and advanced enough to be utilised as academic languages in academia. "This puts pressure on the Department of Higher Education and Training (DHET) to recognise students' different languages in institutions. Section 29 of the South African Constitution further stipulates that we all have the right to learn in our preferred language, but only if it is practical. So currently, we cannot learn in these languages due to the lack of glossaries," Dr Ngubane said.

During the question-and-answer session, Swanti Jerry Thoka, a former Campus Student Representative Council (CSRC) President and Actuarial Science student, cited the policy. "The policy states that it will entail developing previously disadvantaged languages, which includes both indigenous languages and Sign Language, as well as continuing to improve existing ones. Why don't we concentrate on development because the current languages have advanced? For example, a Sign Language policy appears to exist, but it lacks a comprehensive execution strategy," Thoka said. 

Dr Ngubane noted all the remarks and questions, and assured attendees that they would be addressed at the next Council meeting. She stressed the value of students’ participation in policymaking, since their future is being debated. She further explained that students should provide the SRC with recommendations to submit at the Council meetings, because the SRC are their elected representatives.

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.
