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.

Plant scientists address wheat rust diseases at SASPP congress

In his research, Dr Botma Visser, researcher in the Department of Plant Sciences at the University of the Free State, highlighted the population dynamics of the stem rust fungus (Puccinia graminis f. sp. tritici) in Southern Africa. In recent years, two foreign stem rust races were introduced to South Africa, and a local virulence adaptation occurred in a third.

All of these races form part of the Ug99 group, a highly virulent collection of rust races endangering wheat production in many parts of the world. Despite the fact that half of the members of the Ug99 race group is prevalent in South Africa, Dr Visser’s work has clearly shown that Ug99 did not have its origin here. This emphasised the need to include neighbouring countries in the annual stem rust surveys, to proactively identify new races that could threaten local wheat production. In his research, Dr Visser also mentioned the way in which he has optimised modern molecular tools to accurately detect Ug99 isolates.

Dr Visser is one of three scientists from the Department of Plant Sciences that addressed delegates attending the biennial congress of the Southern African Society for Plant Pathology (SASPP) on the Bloemfontein Campus earlier this month on progress regarding research on wheat rust diseases conducted at the UFS.

Howard Castelyn, a PhD student in Plant Sciences, presented his research on quantifying fungal growth of the stem rust pathogen in wheat varieties displaying genetic resistance. This resistance, which is best expressed in adult plants, has the potential to remain durable in the presence of new rust variants. His presentation at the congress focused on optimising microscopic and molecular techniques to track fungal development in stem tissues of adult plants. These results now allow scientists to link rust infection levels and cellular responses with particular resistance genes expressed by the wheat plant, and contributing to the understanding and exploitation of durable resistance.

Prof Zakkie Pretorius presented his research, explaining how new genetic diversity for resistance to the stripe (yellow) rust fungus (Puccinia striiformis) is discovered, analysed and applied in South Africa. This research, conducted in collaboration with Dr Renée Prins and her team at CenGen, is unravelling the genetic basis of stripe rust resistance in a promising wheat line identified by Dr Willem Boshoff, a plant breeder at Pannar. The line and DNA markers to track the resistance genes will soon be introduced to South African wheat breeding programmes.

The rust research programme at the UFS contributes significantly to the successful control of these important crop diseases.

In addition to the contributions by the UFS, rust fungi featured prominently at the SASPP, with first reports of new diseases on sugar cane and Acacia and Eucalyptus trees in South Africa. A case study of the use of a rust fungus as a biological control agent for invasive plant species in the Western Cape, was also presented.
