Message from Prof Francis Petersen, Rector and Vice-Chancellor: 5 March 2021

Dear Senior Undergraduate Students

We are well into the first part of 2021 with the University of the Free State’s (UFS) academic programme that commenced on 1 March 2021.

This communication aims to provide our senior undergraduate students with information and some clarity on how the university is approaching the start of its academic programme and the progress that has been made. The COVID-19 pandemic has posed many challenges to universities across the country; for instance, to find innovative ways of completing the 2020 academic year without leaving any student behind and, at the same time, keeping safety, health, and well-being a top priority.

The pandemic provided ample opportunities to embrace technology and introduce new innovative learning and teaching approaches in 2020, as well as a first-ever online registration process for all our students in 2021. The higher-education landscape is now being reshaped by rapid advances in technology, and this will require continued commitment from all of us to reimage communities that were unimaginable just a decade ago.

With this in mind, one needs to emphasise that any substantial change-management process will pose challenges. To date, 64% of our students who have registered, have done so online. This is a sharp increase from the comparable 20% of last year. I would like to take this opportunity to thank our students and staff for embracing this substantial change in our processes.

However, the university is aware that some of our students find it difficult to register for several reasons, and that this is creating unprecedented anxiety levels among staff and students. It is therefore very important that we identify the underlying blockages and find amicable solutions to ensure that those students who have not yet registered, can do so speedily. Furthermore, it is crucial that the digital skills of our students are developed, as this will be the way in which the university will approach the registration process in the future.

The university’s blended learning programme for 2021 allows for 34% of students to return during the first semester. Although our country is currently on Level 1 of the national lockdown, the percentage of students who return is not linked to the lockdown level, but to the university’s teaching and learning approach and the institution's infrastructure capacity to adhere to physical distancing protocols.

I am aware of the recent comment made by Dr Zweli Mkhize regarding a third wave of COVID-19 post-Easter, as the country continues to roll out its vaccination strategy. Easter is typically a period of family gatherings and the university holidays also follow the Easter weekend. This is yet another reason why the university is exercising caution in its return-to-campus strategy.

To ensure that senior undergraduate students register successfully and can continue with their studies, the following measures have been put into place:

1. The online registration process is extended until Friday 12 March 2021 to allow students who have not yet registered to do so.

2. Classes for selected senior undergraduate students that commenced on or before 1 March 2021, will continue. However, students whose registration has been delayed due to the online registration process, will be supported through a differentiated commencement of classes allowing for a catch-up plan, thus avoiding any student being left behind. Faculties will communicate to these students when online classes will be starting.

3. Additional capacity will be provided to support faculties and campuses in order to expedite the registration process. The university management is aware of the high volumes of enquiries and calls received from students, and this intervention will assist with the turnaround time. In extreme circumstances, students who are identified as vulnerable and are still experiencing challenges with registering, will be requested to do so on campus where they will be assisted in a central venue.

These measures have been put in place for the benefit of our students and to ensure that we can all complete the 2021 academic year successfully.

It is understandable that those students who will not return to the campuses will miss campus life and would like their student life to return to the way it was. However, access to the campuses remains restricted to only registered students for face-to-face teaching and identified postgraduate students in possession of valid 2021 campus-access permits. Permits are being issued centrally and are valid for the period that a student is expected to be on campus. This measure remains in place to ensure compliance with the national regulations and to mitigate the risk of spreading COVID-19.

The dedication and commitment of staff are commendable; they are working tirelessly to support our students during this time, and I thank them for their supportive spirit. In the end, our collective goal is to ensure that our students succeed this year, and that no student is left behind.

Remember that the pandemic continues to test every aspect of society, and although the infection rate is slowly decreasing and the vaccine is rolled out across the country, we must not underestimate the impact that the pandemic still has on local and global communities. Take care of yourselves and those around you and comply with the national guidelines and regulations.

I would like to encourage you to stay in touch with the university. Visit the UFS website and social-media platforms for regular updates and consult your ufs4life email for communication from the university.

I wish you all the best with your studies during the first term and hope to see you on our campuses soon.

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.
