Science for the Future (S4F) summit
Attending the Science for the Future (S4F) summit in the Centenary Complex on the Bloemfontein Campus were, from the left: Back: Dr Cobus van Breda (S4F Programme Director), Amaria Reynders (S4F Family Math Manager), Dr Glynnis Daries (Sol Plaatje University), Prof Francis Petersen (Rector and Vice-Chancellor of the UFS), Tarin Roberts (Nelson Mandela University), Adolph Tomes (Acting Chief Executive Office, SANRAL). In the front are, from the left: Prof Angela James (University of KwaZulu-Natal), Heidi Harper (General Manager Skills Development, SANRAL), Prof Jogymol Alex (Walter Sisulu University).

Teachers from across the country and representatives of six other universities recently gathered at the University of the Free State (UFS) to celebrate the achievements of the Science-for-the-Future (S4F) Teacher Professional Development programmes as well as the successful collaboration between the UFS and other universities.  

The Science-for-the-Future unit in the Faculty of Education hosted a summit in the Centenary Complex on the Bloemfontein Campus on 30 September 2022. The Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, delivered the keynote address at the summit. Representatives from the South African National Roads Agency (SANRAL) – the official sponsors of the Science for the Future initiative – were also present, along with 300 teachers and representatives from the Department of Basic Education. 

In his welcoming address, Prof Patrick Mafora, Vice-Dean of the Faculty of Education, said the initiative exemplifies the UFS’ institutional goals, such as increasing our contribution to local, regional, and global knowledge.  It also supports development and social justice through engaged scholarship.

Improving the quality of teaching and learning for Math and Science 

Dr Cobus van Breda, Programme Director of S4F and Project Manager of the Universities Collaboration initiative, provided background regarding the programmes and stated that “… we know from research that there are many factors that prevent learners in rural areas from excelling in Mathematics and Science. These include subject content knowledge, lack of teaching resources at school and at home, along with a lack of parental involvement, among others.” He said the project aims to address the challenges related to Mathematics and Science teaching and learning in the country. One of the ways in which this goal can be accomplished, is by empowering teachers and learners with the necessary tools, including resources and knowledge, to create a successful learning space for Mathematics and Science. “Our mission is the advancement of innovative and effective Mathematics and Science teaching and learning,” he indicated.

Representatives from the DBE and other institutions were also given the opportunity to highlight the impact of the initiative in their respective institutions. “Our public schooling system, especially in poor and rural areas, is in crisis – more especially in the Eastern Cape. This is due to a lack of learning support and a lack of sufficient skills. This created a need for innovative, sustainable, and tactical solutions to improve the quality of teaching and learning for Math and Science. The Science for the Future initiative is exactly that,” explained Prof Jogy Alex from the Walter Sisulu University.

Making a difference and changing people’s lives 

During his keynote address, Prof Petersen indicated that he preferred the word ‘co-creation’ instead of ‘collaboration’, and he urged the “sponsors not only to contribute funding, but really contribute towards the intellectual project of this programme”. Surely, they have learnings and some ideas that can strengthen and expand the project, he said. Prof Petersen also alluded to the fact that SANRAL contributes towards a Research Chair in Science and Mathematics Education in the Faculty of Education, as well as the fact that, at the university, “we don’t exist to create knowledge for the sake of knowledge; we exist to create knowledge so that the knowledge can make an impact”. He referred to the project as an example of how knowledge is converted to practical application.  


Mr Adolph Tomes, Acting Business Operations Executive at SANRAL, also commended the initiative and its impact. “Although we as SANRAL are the funders and we get praise for being funders, this is a phenomenal project, and it is making a difference and changing people’s lives.”

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.
