Inaugural Dreamwalk 2022
The inaugural dream walk put students in high spirits for the rest of the year, as they were able to express and celebrate their dreams and aspirations.

The inaugural dream walk at the University of the Free State took place on the Bloemfontein Campus on 19 February 2022. The dream walk, also referred to as ‘Leeto la ditoro’, will become an annual event where first-year students come together to express and celebrate their dreams and aspirations. 

The event was well attended by Bloemfontein Campus first-year students, who believe that the event is a great way to set the tone for the rest of the year. The students first gathered at a station on campus, where they were issued with a faculty T-shirt, key chain, a dream card, and a mask. The official walk then began from the Visitor Centre Gate on the northwest side of the Bloemfontein Campus to the Main Building, where members of the senior leadership are based.
During the walk, first-year students had to write down their dreams and aspirations on the dream card, which they ultimately placed in a box at the Main Building. “I found it amazing to be able to put my dreams on paper; it makes them more realistic,” highlighted Marise Prinsloo, a first-year student from the Outeniqua residence. Although some of the aspirations were too personal for some first-year students to speak about, others’ aspirations varied from academic success, spiritual wellness, and mental and physical health. In fact, Malcolm Willemse, who is also a first-year student from Outeniqua, hopes to secure a number of leadership positions. “I have dreams of being in the first-year committee and of being in the sub-committees, and I managed to write these down,” he shared. 

In addition, the atmosphere at the event was vibrant, as the students were excited to engage with one another. “It was amazing to walk with other residences such as Villa Bravado, Abraham Fischer, and Conlaurês, as they have great spirit,’’ expressed Willemse. The walk included songs from the various residences, and the first-year students were dancing and singing along. However, the fun did not end there. Once the students arrived at the Main Building, they were treated to a DJ who had them dancing and singing even more.

As the dream walk event will also take place on the Qwaqwa and South Campuses, the students on these campuses can expect to take part in a lot of singing, dancing, and other cultural activities. Precious Modiba, who is also a first-year student, argues that besides having a good time, one of the best things about the dream walk is the friends that one gets to make.

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.
