Student from the Umoja Buddy programme
Students from all corners of the globe forge lasting bonds through the Umoja Buddy Programme.

Let’s say you find yourself attending a university in a different country where you need to adjust to a new language, culture, environment, friends, lecturers, curriculum, and lifestyle. Sounds like a challenging leap of faith, right? However, the Umoja Buddy Programme (UBP) makes this transition a whole lot easier for international students.

If you were an international student at the University of the Free State’s (UFS) Bloemfontein Campus, you would be assigned a buddy who is familiar with student life and community. The Office for International Affairs in collaboration with Student Affairs designed this programme for all incoming exchange students to feel welcome and at home.

The UBP is part of the university’s endeavours to advance internationalisation at home, which was entrenched in the 2018-2022 UFS Internationalisation Strategy. Underlying is the idea to provide UFS students with international experiences on their home campus.

Integration at the heart of internationalisation


At the Bloemfontein Campus launch of the UBP on 14 February 2019, UFS Rector and Vice-Chancellor, Prof Francis Petersen, welcomed this year’s cohort of first-time international students and highlighted the importance of the UBP. “In essence, it aims to connect international and local students through meaningful lifelong friendships and to foster their academic, social and cultural integration at the UFS,” he said.

Prof Petersen strongly believes in the programme’s ability to facilitate “cross-fertilisation of ideas and intercultural exposure and learning”, which further enhances the quality of graduates produced by the institution.

A student is a student through other students


Lesotho-born Precious Lesupi volunteered as one of the 48 ambassadors to prevent others from experiencing the difficulties she did when she arrived at UFS. “I have been in a situation where you get to a place and you know nothing about the people there, especially the culture, and the way everything is done because you come from a totally different place, so it’s really hard to adjust.”

Lebohang Lesenyeho, who hails from Botshabelo in the Free State, expressed similar sentiments with fellow ambassador,Kweku Gavor. He said he “looks forward to “building a meaningful relationship.” Kweku who has Ghanaian origins believes that, “you cannot put a price on learning about another person and ways you react to certain situations.”


Umoja is a verb


True to the word umoja, which means “unity and the spirit of togetherness”, the programme has proved to bring together students from diverse backgrounds in the pursuit of academic excellence. The goal can be best achieved when complemented by a holistic social and cultural experience.

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.
