Mother tongue pride

A unique public speaking competition hosted in the small town of Philippolis has done wonders to not only build confidence in young mother tongue speakers, but to broaden the cultural perspectives of an entire community.

The Philippolis Public Speaking Competition has been hosted by the Unit for Language Facilitation and Empowerment (ULFE) and the Department of Community Engagement (CE) at the University of the Free State (UFS) since 2013. What started as a small competition for learners in this Southern Free State town, has grown into a much-anticipated annual event, drawing participants from schools in neighbouring towns such as Trompsburg, Bethulie, Jagersfontein, Fauresmith, Gariepdam, and Reddersburg.

Talking about heritage

Every year, learners from Grades 6 to 9 are invited to present a speech on a specific heritage-related topic. Participants are encouraged to speak in their mother tongues – which in this region are mainly Afrikaans, Sesotho, Setswana, and isiXhosa.

Interpreters from the UFS ULFE ensure that the audience can follow each speech. For the past few years, deaf learners from the Bartimea School for the Deaf and Blind in Thaba Nchu and Re Tlameleng School for the Deaf in Kimberley have made welcome appearances, assisted by UFS sign language interpreters.

“This is a wonderful opportunity to teach our young people about acknowledging and respecting different opinions – but also to consider perspectives from differently abled individuals,” enthuses Anita Muller, a teacher from Bergmanshoogte Primary School, who has been involved in the competition from the very beginning.

“Learners in rural areas so often believe they don’t have a voice, and that nobody is interested in their opinions,” she continues.

“This competition does wonderful work in building feelings of self-worth and self-confidence. And it is usually a welcome opportunity for our broader community to get together, learn about one another’s cultures, and change perspectives.” 

Embracing individuality

Jani de Lange, UFS Lecturer in South African Sign Language and Deaf Studies, and one of the coordinators of the project, says she was excited to note that the master of ceremonies of last year’s competition was a former participant in the very first event.

“This project gives me a sense of pride and reminds me why I am part of the UFS. It has been a real eye-opener to see how important it is for those involved,” she says.

“It encourages our young people to embrace their individuality, as we celebrate the cultures and traditions of all those who participate,” says Mabatho Ntsieng from the Engaged Scholarship Office. She says young people often lose sight of where they come from. By giving them opportunities to research topics linked to their heritage and then present their speech in their mother tongue, they can return to their cultural roots.

“It is wonderful to see how proud these participants are and the impact it has on the schools and the community.”

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.
