GreenerSA
Jeminah Seqela from Food and Trees for Africa demonstrates tree planting as part of the initiative to plant 100 trees on the day.

The University of the Free State (UFS) launched Greener SA, a five-year initiative to plant 400 000 trees across South Africa, at the Paradys Experimental Farm on Friday 12 September 2025. Backed by the Mastercard Foundation through the TAGDev 2.0 programme and RUFORUM, the project brings together government, industry, students, and academics around a shared commitment to sustainability and food security. The launch was marked by the planting of the first 100 trees, a symbolic act that set the tone for the years ahead.

Prof Jan-Willem Swanepoel, Director of the Centre for Sustainable Agriculture, reminded the audience that the UFS is one of 12 African universities entrusted with a $100 million investment in agricultural transformation. “This project is not a hit-and-run – it’s about sustainability, inclusivity, and building value chains that empower farmers and entrepreneurs,” he said. He ended with a parable of a farmhand who could ‘sleep when the wind blows,’ urging everyone to be proactive in preparing for inevitable challenges.

 

Responsibility and partnerships

That call for responsibility was echoed by Elzabe Rockman, Free State MEC for Agriculture and Rural Development, who linked Greener SA to the presidential One Million Trees Programme. She cautioned that planting without accountability leads to wasted effort. “If we plant trees, we want to be sure someone takes responsibility for them,” she said, highlighting the need for fire-resistant species, fruit trees in community gardens, and natural borders to replace vulnerable fencing. Looking at the students from Kovsie ACT who joined the launch, she added: “Jobs are not going to fall from the sky. They will come from agriculture and the environment. Harnessing youth energy is the way forward.”

Industry also pledged its support. Representing Empact Group – the sponsor of the trees – Helena Prinsloo described tree planting as an investment in legacy. “At Empact Group, we believe that doing right by our community and our planet is not just a responsibility. It’s a value that defines who we are and how we lead,” she said. Quoting the proverb that societies grow great when people plant trees whose shade they will never sit in, she added: “Today we are sowing seeds of hope, resilience, and opportunities for generations to come.”

 

Science, vision, and practice

Prof Corli Witthuhn from the Faculty of Natural and Agricultural Sciences placed the launch in a global context, pointing to conflict, inequality, and climate change – and the sobering United Nations report showing that only 20% of the sustainability goals have been achieved. For her, the Greener SA project is a response to urgent global challenges. “We want our students to be globally work-ready,” she said. “That means beyond textbooks, and this farm represents exactly that. We don’t want to produce graduates with degrees, we want to produce graduates who can walk into a lab, into a policy meeting, into a business anywhere in the world and make an impact.”

Her message was supported by expert voices. Guest speaker Prof Ben du Toit from Stellenbosch University explained that agroforestry systems can simultaneously provide timber, food, biodiversity, and resilience. “Agroforestry is not planting trees over here and grazing over there – it’s about integration, so that benefits reinforce each other,” he said.

At the Paradys Experimental Farm, this integration is already underway. Johan Barnard, Farm Manager and Junior Lecturer, described how shaded tree pockets will improve grazing fields and protect water resources, while fruit trees planted in partnership with Kovsie ACT will contribute to student nutrition and new food value chains. “We’re capturing value chains and taking it to the next level so that our students have research opportunities and the farm delivers real outputs,” he explained.

The launch of Greener SA showed that tree planting is about much more than beautification. It is a collective commitment – to resilience in the face of global challenges, to science applied in practice, and to building partnerships that prepare the next generation to make an impact.

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.
