At the signing of the Memorandum of Agreement between the UFS and local community radio stations were, from the left (front row): Lebogang Matolong, Station Manager of Motheo FM, and Prof Puleng LenkaBula, Vice-Rector: Institutional Change, Student Affairs, and Community Engagement. At the back (standing), are from the left: Mohau Rampeta, Programme Manager of Motheo FM, and Bishop Billyboy Ramahlele, Director: Community Engagement.

In response to the current COVID-19 pandemic, the Directorate: Community Engagement (CE) has initiated an innovative platform on which students can continue to engage with university community partners, and at the same time be assessed for their service-learning and community engagement projects. 

The E-Engagement approach also meets the University of the Free State’s (UFS) strategic mandate to be a caring, responsive, and engaged university. Coordinated by the UFS CE office, academic staff and students are scheduled to engage with the community partners through radio broadcasts and virtual mode platforms. Informative content that has been researched, prepared, and presented by students in a pre-recorded format, will address significant issues brought about by the surge of COVID-19, creating a breeding ground for some of the societal ills, such as gender-based violence (GBV).

In order to establish sustainable relationships with community radio stations, a Memorandum of Agreement (MOA) with two local community radio stations was signed on the UFS Bloemfontein Campus on 10 October 2020. Prof Puleng LenkaBula, the Vice-Rector: Institutional Change, Student Affairs, and Community Engagement, and Bishop Billyboy Ramahlele, CE Director, participated in the commitment to formalise the relationship between the UFS and the two radio stations, Mosupatsela FM and Motheo FM.

Master’s students from the Department of Psychology have produced and pre-recorded podcasts on community psychology. Their topics covered grief and self-compassion. The Department of Nutrition and Dietetics presented topics on a healthy lifestyle and diet. Fourth-year students from the School of Nursing have engaged new mothers concerning post-natal care. The School of Clinical Medicine has addressed the warning signs of burnout and preventative measures.

Bishop Ramahlele emphasised the importance of sustained relationship, which is expected to create further opportunities for interaction through partnerships in skills training (ICT) and the sharing of resources, including consultations through conference platforms. Prof LenkaBula highlighted the significance of the MOA by applauding the initiative, which has unlimited potential to ensure national development through student engagement, since universities create development sites that can be transferred further into 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.
