G20 - 2025
G20 delegates from member countries and other invited guests in attendance at the G20 Research and Innovation Working Group (RIWG) and G20 Initiative on Bioeconomy (GIB) meetings and other side events.

Against the backdrop of the upcoming G20 Summit to be hosted by South Africa in November 2025, the University of the Free State (UFS) – in partnership with the Department of Science, Technology and Innovation (DSTI) – held the G20 Research and Innovation Working Group (RIWG) and G20 Initiative on Bioeconomy (GIB) meetings on 23 and 24 February 2025.

In her opening address to G20 delegates from member countries, national and international knowledge partners, members of the Free State provincial government, and representatives of the DSTI, Prof Hester Klopper, Vice-Chancellor and Principal of the UFS, indicated, “It is an honour for the UFS to be among the few South African universities to host this essential Research and Innovation Working Group.” In addition, she highlighted that the deliberations and discussions set to take place during this important workshop can set in motion chains of events ultimately contributing to improved lives for everyone. These sentiments were also echoed by Prof Blade Nzimande, Minister of Science, Technology and Innovation, who underscored the importance and historic nature of the upcoming G20 Summit.

In his virtual address, Minister Nzimande explained that South Africa’s chosen theme for the G20 Summit – Solidarity, Equality and Sustainability – was inspired by the general complexity of our time, “in particular the transnational nature of these complexities, such as conflict, the displacement of people, poverty”, among other things. As such, he expressed that in this case, cooperation among nations is becoming increasingly essential.

As they concluded their addresses, Prof Nzimande and Prof Klopper, wished the delegates well in their deliberations. ‘’May your discussions be successful, and your goals be achieved. And may your time with us lead to a renewed experience of the value of innovation through connection, ‘’expressed Prof Klopper.

 

Contributing events

As part of the programme at these proceedings, several side events took place. These included panel discussions with indigenous knowledge holders such as Telle Hoeses, Chief Language Practitioner for Khoi and San Languages, along with experts of indigenous medicine. The conversation focused on indigenous knowledge systems (IKS) and some of the key concerns and progress that these knowledge holders have made in the space. In addition, these knowledge holders, many of whom are business owners who sell products made from indigenous medicines, also had the opportunity to exhibit their products. According to Dan du Toit, Deputy Director-General: International Cooperation and Resources at the DSTI, these panel discussions with young people, bioeconomy researchers, and indigenous knowledge holders were an opportunity to gain access to a diversity of voices, which would not normally find expression in formal meetings. “It is also an opportunity for our international guests to get insight into who we are as a country and what some of our concerns might be,” said Du Toit.

One of the highly anticipated side events on the programme was the joint G20 RIWG and GIB event titled ‘UNESCO Women and Girls in Science’, which took place on 25 February 2025. The event took the form of a round-table discussion, in an attempt to answer the question: Based on your experiences in various roles within higher education in South Africa, Africa, and globally, what are some key insights regarding the role of universities in closing the gender gap in STEM, specifically concerning professional development and creating supportive research environments where everyone, especially women, can thrive?

Prof Anthea Rhoda; Deputy Vice-Chancellor: Academic at the UFS, was one of the contributors in this session. In response to the question, Prof Rhoda highlighted, “Universities should also be spaces characterised by intellectual freedom and freedom of expression, where archaic ideas about male superiority and patriarchy can be openly confronted and contested, without fear of victimisation. She expressed that an active way in which the UFS has committed itself to a culture of diversity and inclusion is through Vision130.

As she was wrapping up her address, Prof Rhoda also highlighted, “To address areas of underrepresentation of women in senior academic and leadership positions within the university, a Working Group on Gender Parity in Academic Leadership was established, with the critical mandate to drive attitudinal shifts, advocate for changes where necessary, and highlight barriers to women’s advancement.”

 

The programme comes to an end

The last day of the programme was reserved for comments, reflections, and discussions on deliverables. As such, there were positive responses to the way the deliberations took place. In fact, Hoese, speaking in her capacity as an indigenous knowledge holder, said, “This was a good platform for us to make progress towards language recognition and officialisation.”

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
