Global Social Innovation Indaba
Panel discussion during the 2024 Global Social Innovation Indaba held at the University of the Free State, Bloemfontein Campus.

Insightful, thought-provoking and inspiring: These were some of the words used to describe the 2024 Global Social Innovation Indaba, which took place at the Centenary Complex on the University of the Free State’s (UFS’s) Bloemfontein Campus from 30 September to 2 October 2024.

The three-day conference was hosted by the global Social Innovation Exchange (SIX) in collaboration with the UFS, under the theme ‘People Powered Change’. The conference brought together leaders and innovators from South Africa and several other countries, including Louise Pulford, CEO of SIX; Markus Lux, Senior Vice-President at Robert Bosch Stiftung, and Desmond D’Sa from the South Durban Community Environment Alliance (SDCEA), among others.

In her opening address, Acting UFS Vice-Chancellor and Principal Prof Anthea Rhoda welcomed the guests and described the conference as an opportunity to “deliberate, debate, and dissect ideas around the all-important topic of harnessing people-powered change in order to build successful societies”.

Powering social change

As part of the conference guests engaged in a series of panel discussions and activities, and attended presentations on various topics.

D’Sa was one of the first speakers, delivering a keynote address titled ‘An activist guide to people-powered change’. He referred to moments throughout his career in which he has actively worked towards change in his community and beyond, and highlighted some of the work the SDCEA continues to do. Guests were also treated to a spoken word performance by Napo Masheane, Artistic Director at the Performing Arts Centre of the Free State (PACOFS).

Advocate Tembeka Ngcukaitobi touched on several points in his talk, such as what the law meant or means to indigenous people. He explored this by referring back to the colonialist era. Ngcukaitobi, who described law as the most ubiquitous and most stable concept that European settlers brought, indicated that it was brought in two faces: the face of justice, and the face of violence. Therefore, he said, “… the future of law that has been most enduring is the ability of the law to transform itself from violence to justice.”

Guests said they regarded the presentations and dialogues as insightful, and also highlighted their appreciation for being able to interact with the campus itself. This sentiment in large part stemmed from the attendees being split into smaller groups and taken to see different parts of the campus. They also got to see an exhibition exploring the role of art in social justice at the Department of Fine Arts.

Lessons from the conference

The last day featured a panel discussion titled ‘Challenging power dynamics and redefining global exchange’, which included an engagement session with the audience. Guests were able to reflect on the information they had acquired at the conference and challenged themselves to continue working towards change and innovation.

“What I learnt from these three days is that since we all want to do the right thing, we all know what the job that needs to be done is,” said Michael Ngigi, CEO of Thinkplace Africa. “As such, we need to be bold in going for that, and really push back on the status quo that is formed by the places we represent.”

UFS researcher engineers metal surfaces

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
