KMUN 2023
Young leaders unite! Fostering diplomacy and innovation – The Kovsies Model UN Summit 2023 shaped future global change makers!

The saying goes, ‘Leaders are born, not made,’ but what term do we use when more than 50 young individuals from various institutions gather to address and tackle many of our global socio-economic issues collectively?

The University of the Free State United Nations (UN) Chapter hosted the first of many Kovsies Model United Nations (KMUN) Summits – a simulation of the UN General Assembly (GA) – from 28 to 30 July 2023. The event brought together students from various institutions, including the University of Pretoria (UP), Wits, North-West University (NWU), as well as the UFS South and Qwaqwa campuses, who convened on the UFS Bloemfontein Campus for this prestigious gathering.

The students represented different countries and embarked on a comprehensive research project focused on the challenges faced by their respective nations and their progress in addressing them, which they had to present at the GA. Their investigations encompassed various Sustainable Development Goals (SDGs), including poverty eradication, building partnerships, promoting quality education, and advancing gender equality. These efforts align perfectly with the university's Vision 130, which is dedicated to promoting academic excellence, fostering social impact, and embracing diversity.

Siphilangenkosi Dlamini, Executive Chair of the UN Association of South Africa’s UFS Chapter and Student Assistant in the UFS Centre for Teaching and Learning (CTL), said that the summit served as a platform to bring together young people and student leaders from participating institutions to address an array of issues as if they were leaders of different countries.

"Our objective was to create a platform where these young minds could participate in constructive dialogues, refine their diplomatic skills, and address urgent global challenges. The most remarkable aspect was observing the participants' passion and dedication. Witnessing them wholeheartedly embrace the principles of diplomacy and cooperation was genuinely uplifting.”

Moreover, the attendees expressed their appreciation for this prestigious event, as it provided them with invaluable information and insights into what the future holds for them.

Keoratile Moloto, a North-West University student who proudly represented Belize – a Central American country – emphasised that this unique experience provided him with a valuable opportunity to acquire knowledge. As a student leader, he believed that this knowledge could positively influence and inspire both those he served and those in leadership positions.

“This is a too exciting initiative to ignore as a young individual who aspires to improve the world. I have always envisioned a time where I can make a difference in a community. I am big on most SDGs and saw this opportunity as a stepping-stone to educate myself on the proceedings. It is an awesome experience to engage with these topics rather than just being a viewer.”

Students were encouraged to collaborate and be active observers of pressing issues that affect their future. Student Affairs Assistant Director, Motlogelwa Moema, also advised the delegates to approach the debates with an open mind, network, familiarise themselves with the SDGs, and develop sustainable, innovative solutions to these socio-economic challenges.

This summit proved to be an enriching and transformative experience for all participants. From engaging in diplomatic negotiations to tackling global issues, delegates developed crucial leadership skills, fostered diplomacy, and shaped the future of international relations. As delegates from prestigious universities came together, the discussions were diverse, thought-provoking, and inspiring. Undoubtedly, the KMUN Summit left a lasting impact on the delegates and contributed to developing future leaders who would make a positive difference on the global stage.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
