UFS official opening
Kovsies is on track with the firm foundation laid in previous years. 2020 is a year where visibility and impact is the key theme.

WATCH: Official Opening 2020

Tackling 2020 with rigour and vigour is the top priority for the University of the Free State’s agenda and it’s all systems go after a year of building a solid foundation. Prof Francis Petersen, UFS Rector and Vice-Chancellor, addressed staff in his official Opening speech at the Bloemfontein Campus on Friday 7 February 2020.

“The university is on track with what it set out to deliver in 2019” Prof Petersen shared the successes of 2019 with the audience and outlined his vision and plans for 2020 with visibility and impact as the key themes. 

Prof Petersen urged staff to work hand-in-hand to ensure an outcome that generations will inherit with pride. “We have our eyes firmly set on the far horizon, to ensure that we bestow an institution on the next generation that is different from the past, a place where every essence is in perpetual renewal. That means every one of us is smaller than the institution, and every one of us needs to lay a brick that builds a university that is different from the past, more impressive than the past, an institution that will grow constantly.” 

Setting the pace

As a frame of reference, Prof Petersen pointed to engagement, conversation, clear communication and decisive action to yield the type of environment in which we all want to work and study. “I can assure you that we will continue with that engagement, in a sphere of respect, tolerance for different views by always focusing on what the Integrated Transformation Plan (ITP) stands for – which is fairness and social justice.”

Reflecting on the year that was.


Prof Petersen reflected on 2019 as a year which focused on a return on investment delivery as it relates to the Strategic Plan, ITP, seven Vice-Chancellor’s projects, institutional and multi-stakeholder group and institutional Risk Register. These guiding documents laid a firm foundation for implementation processes to take place this year.

Leading the way

The Rector related some success stories which include the increased number of NRF-rated researchers. “In the area of student success, we are probably leading the country and our inputs are globally known.”

As a national leader on the infrastructural and student accommodation front, the Department of Higher Education, Science and Technology often consults the UFS for advice on how other institutions can adequately spend their infrastructure grants. Moving forward, the university also plans to partner more with national and international institutions of higher learning with the aim of strengthening research and innovation ties.

On inclusiveness and social cohesion

Pressing issues such as gender-based violence and xenophobia are constantly being tackled by the Unit for Institutional Change and Social Justice in collaboration with other academic and support services. These parties have conducted and developed critical conversations, position papers, and policies to guide the institution towards an inclusive and socially cohesive space which embraces the values of ubuntu and respect.

In closing, Prof Petersen reminded the university community of the crucial role each individual plays in building a bright future. “We must always remember that the UFS exists through its staff and students and should never let one of them feel neglected or unheard.”

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.
