Collaborating across continents, the Centre for Gender and Africa Studies at the University of the Free State (UFS), alongside the Centre for African Studies at Jawaharlal Nehru University (JNU) in India and the African Studies Association of India (ASA India), held a pivotal international webinar titled 'Africa’s Global Engagements: Opportunities and Challenges,' on 27 and 28 January 2024.

In the midst of a global landscape marked by rapid changes, Africa finds itself at the epicentre of a new wave of international interest. This intrigue stems from a myriad of factors, ranging from the continent’s abundant natural resources to its strategic geopolitical positioning. However, amidst this renewed attention, questions arise regarding Africa’s agency and its place in the evolving global order.

In recent times, there has been a notable surge in global actors vying for influence in Africa. From former colonial powers to emerging economies like China and India, various stakeholders seek to engage African nations on multiple fronts, spanning from economic cooperation to security collaborations. Against this backdrop, it becomes imperative to delve into Africa’s international engagements to grasp the nuances of its evolving role on the global stage.

Addressing this imperative, the Centre for Gender and Africa Studies at the University of the Free State (UFS), in collaboration with the Centre for African Studies at Jawaharlal Nehru University (JNU) in India and the African Studies Association of India (ASA India), convened an international webinar titled, Africa’s Global Engagements: Opportunities and Challenges. Held on 27 and 28 February 2024, the event was jointly opened by Prof Vasu Reddy, Deputy Vice-Chancellor of Research and Internationalisation at the UFS and Prof Ajay Dubey, former Pro Vice-Chancellor at JNU and currently a professor in the Centre for Africa Studies at JNU. The conference brought together scholars and policymakers from diverse backgrounds and regions, united in their quest to comprehensively understand Africa’s evolving position in the global arena.

In his opening remarks, Prof Vasu Reddy, underscored the timeliness of the conference aligning it to the institution’s visionary framework, Vision 130. He highlighted the centering of Africa as a focal point for addressing broader global challenges emphasising the interconnectedness of Africa’s experiences with broader global narratives. Prof Reddy articulated how Africa serves as a nexus for transnational interactions, intertwining diverse histories, politics, and socio-economic dynamics with the larger global discourse.

Moreover, the conference shed light on the concept of the “Global South” and its implications in the contemporary global order. Participants deliberated on the complexities of African agency within this framework, examining how African states navigate their engagements with a myriad of international actors while asserting their own interests and priorities.

The event not only symbolised a collaboration between the UFS and JNU, as outlined in their Memorandum of Understanding (MoU), but also signified a shared commitment towards prioritising engagements within the Global South. Through platforms like these, institutions like UFS and JNU demonstrate their dedication to fostering meaningful dialogues and scholarly exchanges that transcend geographical borders.

As Africa continues to navigate its place in the fast-changing global landscape, initiatives such as this webinar serve as critical platforms for fostering mutual understanding and cooperation among scholars and policymakers worldwide. By engaging in nuanced discussions and collaborative efforts, stakeholders can collectively contribute to shaping a more inclusive and equitable global order.

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.
