The University of the Free State Library and Information Services (UFSLIS) hosted stakeholders from SABC Lesedi FM, the Free State Department of Sport, Arts, and Culture, the Pan South African Language Board (PanSALB), and delegates from the National Library for the launch of the first-ever African Languages University Press in South Africa and Africa.  The launch, which took place on 24 May, deliberately coincided with the Africa Month commemorations – as the UFS’ answer to the United Nations General Assembly (Resolution A/RES/74/135) proclamation of the period between 2022 and 2032 as the International Decade of Indigenous Languages.  

This proclamation aims to draw global attention to the critical situation of many indigenous languages, and to mobilise stakeholders and resources for their preservation, revitalisation, and promotion. The University of the Free State Department of African Languages aims to be a publisher of high-quality original African language monographs and research in order to promote access, preservation, and use of marginalised African languages.  

In his opening remarks, Marcus Maphile, Assistant Director: Library Services, said, “As a broad academic publisher, the African Languages Press will be working across a number of markets, all presenting challenges and opportunities for established and engaged university presses. One of the opportunities will be to challenge the mainstream book publishers to re-enter the indigenous language publishing market.” He further said that this was done to make writing and reading in African indigenous languages fashionable, for other nations to envy our rich multilingual cultural heritage. 

The guest speaker for the launch was the UFS honorary Doctor of Letters (DLitt) recipient, Dr Jerry Mofokeng wa Makhetha, who applauded the University of the Free State for taking such a bold step towards enriching and developing African indigenous languages. 

The launch offered the UFS the opportunity to reach out and engage the international community on potential partnerships and collaborations towards developing African languages. The Library Director, Ms Jeanette Molopyane, provided insight into the challenges faced by libraries due to the shortage of books in African languages, while positioning the University of the Free State Library as a trendsetter and a leader in the development of best practices in the field of libraries.

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.
