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.”

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
