SANRAL Chief Executive Officer Skhumbuzo Macozoma and UFS Rector and Vice-Chancellor Prof Francis Petersen cutting a cake to mark 10 years of collaboration between the two institutions.

The Science-for-the-Future (S4F) programme is fundamental to generating the required pipeline for technologically skilled entrepreneurs and workers by focusing on Mathematics and Science support to learners, teachers, and parents.

This is according to the South African National Roads Agency Limited (SANRAL) Chief Executive Officer, Skhumbuzo Macozoma, who delivered a keynote address at the Annual Science for the Future Summit held at the University of the Free State (UFS) on 20 September.

The S4F is a partnership between the UFS and SANRAL, with the fundamental purpose to train Maths and Science teachers and to support learners and parents. The programme has now been extended to six other universities, namely Nelson Mandela University and Walter Sisulu University in the Eastern Cape; the University of Limpopo, University of KwaZulu-Natal, and the two recently established universities, the University of Mpumalanga and the Sol Plaatje University in the Northern Cape.

Dr Cobus van Breda, the Programme Director for the UFS S4S, said they developed the Family Math and Key Concepts in Science programmes to address issues that prevent learners from excelling in these critical subjects. It seeks to improve the content knowledge of teachers and provide them with more skills-teaching resources.

Macozoma said: “I am proud and deeply honoured to stand before you today in the strength of a successful 10-year partnership with the University of the Free State which we are celebrating here today, together with the hosting of the Annual Science for the Future Summit.”  More than 300 teachers attended the summit.

Planning for the future

He indicated that SANRAL's long-term strategy, Horizon 2030, instructed the development of a new human-resources strategy for the organisation, which has identified three pillars that underpin SANRAL's human-capital development initiatives, namely people, skills, and performance.

“The strategic opportunities identified by SANRAL include capitalising on the opportunity presented by the digital revolution to create a new generation of technologically skilled entrepreneurs and workers; returning to good and ethical governance in both the public and private sectors; bringing back the prestige of serving the citizens of SA through state institutions: fashioning SANRAL as an employer of the future and delivering technical skills to address the glaring skills gap in engineering and other domains,” he said.

Macozoma stated that SANRAL has also decided to review and rationalise its support to institutions of higher learning in order to grow the footprint of its support programmes, increase the impact, and ensure equity.

Beyond this, he stated that SANRAL wanted to ensure that learners are equipped with fundamental competencies that are essential to complement academic teachings, including critical thinking, creativity, collaboration, communication, information literacy, media literacy, technology literacy, and flexibility.         

Facing 4IR head on

Macozoma said the most important characteristics of the Fourth Industrial Revolution that must be taken into consideration by those who aim to survive it, drive it, and benefit from it, is a smart customer – who is informed and dictates what services he/she wants and how they should be delivered; technology at the fingertips – which will enable rapid, real-time, borderless services to information, services, and technology as an enabler – bringing efficiency to logistics, mobility, medicine, education, industries, the economy, the military, global trade, and politics.  

Working closely with school and society

UFS Rector and Vice-Chancellor, Prof Francis Petersen, said the university has an important responsibility to generate knowledge that will impact society positively.

“We have a role to work closely with our schools and society so that we can understand each other’s needs,” he said.

“We need to strengthen collaboration with all our partners so that we can travel further and make an impact in our society,” said Prof Petersen.

One of the participating teachers in the S4F programme, Grace Molante, from a primary school in Zastron, said: “It is programmes such as these that instil hope in us as teachers. Some learners could find Maths and Science very difficult and challenging subjects, but this programme makes problem solving more enjoyable and practical.”

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.
