Mbulelo Aven Jafta, Xhariep Municipality Corporate Services Director, and Dr Engela van Staden, Deputy Vice-Chancellor: Academic at the UFS, sign a memorandum of understanding to enrich various communities in the Xhariep Municipality areas through leadership training.

The University of the Free State (UFS) has signed a memorandum of understanding with the South African Local Government Association (SALGA) and the Xhariep Municipality that is aimed at positively impacting communities through strategic partnerships. The organisations plan for their collaboration to make a significant difference by training 35 of their employees via the UFS Business School – 15 will undertake the Foundation Skills Short Learning Programme, and 20 the Bachelor’s degree in Management Leadership.

This joint effort will equip these employees with essential skills and knowledge and empower them to carry out their responsibilities efficiently and effectively. Rooted in the UFS’s Vision 130, this initiative fosters positive change within the community by enhancing social justice and innovation.

Dr Engela van Staden, Deputy Vice-Chancellor: Academic at the UFS, emphasised the university's dedication to human resource development and empowering individuals. “We were very excited when we got this engagement with you, and I hope it will be fruitful for you, because that’s the intention. We are also reaching out to other municipalities because we are doing it for our country, and the sooner we do it, the better the services you will deliver to people.” 

Xhariep Municipality expressed gratitude for the collaboration, recognising its significance in empowering its employees. Mbulelo Aven Jafta, Corporate Services Director at the municipality, thanked the university for accepting the partnership. “As a municipality, we are interested in capacitating our employees to perform their duties optimally. It is through these partnerships that we reach our intended targets. This is the first two projects, and many more will be coming as our partnership progresses, and we intend to use this opportunity to the best of our abilities.”

Jafta said that such partnerships encourage a more interconnected and interdependent world. “As organisations work towards common goals, they create a ripple effect that can lead to a brighter and more promising future and play a vital role in shaping a positive and sustainable future.”

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.
