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.”

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
