Student Success
The UFS is committed to student success through its own initiative.

In its endeavour to assist and support academically deserving students, taking into account the current economic climate in South Africa, the University of the Free State (UFS) has been able to maintain its approach to student success from its own initiative and in cooperation with external sources or partners. 
 
In addition, the university’s tuition fees remain on average 20% less than those of comparative universities.
 
“More than 70% of all registered undergraduate and postgraduate students at the UFS are receiving some kind of financial support – whether from the university or via external sources or partners, or from the National Student Financial Aid Scheme (NSFAS). In fact, financial support to students is one of the main expenses of the university,” says Mr Chris Liebenberg, Senior Director: Finance at the UFS. 
 
According to Mr Liebenberg, undergraduate bursaries to the value of R63 million and postgraduate bursaries to the value of R77 million have been allocated for 2019. These bursaries are funded by the UFS, as well as by external sources or partners and are awarded on merit, which includes academic, sport, and cultural performance. It excludes bursaries that students receive from NSFAS. 
 
“The university is able to provide this support to deserving students due to its stringent application of financial governance and discipline and within a framework of financial sustainability. It is a principle that the university management strongly believes in and will continue to apply,” says Mr Liebenberg.

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.
