Hosting the South African Circular Agriculture Initiative (SACAI) – an initiative of the Department of Science, Technology and Innovation’s (DSTI) – will help position the Green Futures Hub at the University of the Free State (UFS) as a leader in circularity in agriculture.

The UFS Green Futures Hub was selected to host the SACAI from 1 January 2025-31 March 2026. The funding received will be used to conduct workshops with stakeholders to develop a strategy to strengthen South Africa’s science, technology, and innovation for a circular economy in the agriculture sector.

The SACAI, under the leadership of Prof Wayne Truter, Research Professor at the UFS Centre for Mineral Biogeochemistry, and Executive Management of the UFS Green Futures Hub, aims to advance the principles of the circular economy and modernise agriculture in line with the South African government's aspirations. These goals are outlined in the Science, Technology, and Innovation (STI) Decadal Plan (2022-2032) and the Circular Economy STI Strategy.

 

Elevating the UFS’ visibility

The UFS Green Future Hub is a virtual platform in the Faculty of Natural and Agricultural Sciences (NAS), to facilitate integration and leverage capabilities to facilitate third stream funding and industry collaboration. It provides an interface and support structure for researchers to engage with funders and partners through the Hub.

Prof Truter says it is a great honour and privilege to have been awarded this initiative. “The funding that comes with SACAI will elevate our visibility in agriculture in the country and will help position Green Futures Hub as a leader in circularity in agriculture. A key objective of SACAI is to leverage science, technology, and innovation to enhance the value of the national system of innovation (NSI) within the agriculture sector. 

“The initiative will align with the priorities set out in the Circular Economy STI Strategy (2024-2034), focusing on resource efficiency, regenerative agriculture, sustainable agro-processing, and biorefinery development in South Africa. Through collaborations with other public research institutions, the hub will drive STI implementation in these critical areas,” says Prof Truter.

 

Objectives of SACAI 

The objective of SACAI is to give effect to the (i) circular economy, and (ii) modernising agriculture, aspirations of the South African government. The SACAI aims to advance the principles of the circular economy and modernise agriculture in line with the South African government’s aspirations. 

Simultaneously, Prof Truter explains, the objectives of the SACAI align with the vision of the UFS Green Futures Hub to be a global leader in advancing the understanding and application of sustainable practices for life with land and water, in developing contexts. By leveraging the latest advancements in research, technology, and innovation, the hub aims to create a thriving future where communities harmonise with natural and agricultural environments, ensuring the well-being of current and future generations, which has a particular focus on modernising agriculture and capacity development. 

Through STI, the SACAI will support the South African agriculture sector to adopt, scale and accelerate circular practices and technology. The SACAI will act through a hub-and-spoke model, to build and strengthen a national system of innovation, and associated capability, and will establish and strengthen strategic regional and international STI partnerships, to directly support industry and other sector stakeholders, serving as a facilitator of relevant research and related outputs.

 

UFS’ Vision 130 

“A South African Circular Agricultural Initiative perfectly aligns with our research-led, student-centred, and regionally engaged university by driving innovation and knowledge production in sustainable agriculture. This initiative will enable the university to contribute to development and social justice by advancing circular farming practices that reduce waste, optimise resources, and promote environmental sustainability, particularly in rural areas. 

“This fosters greater food security and resilience, benefiting marginalised communities, and addressing social inequalities within the agricultural sector. By involving our students, this initiative will directly support the student-centred approach, offering hands-on learning experiences that equip graduates with cutting-edge skills in circular economy principles,” says Prof Truter. 

The university’s Vision 130 focus on diversity, inclusion, and equity is reflected in the initiative’s emphasis on sharing knowledge and resources equitably, ensuring maximum societal impact and advancing a more just and sustainable agricultural system across South Africa.

Prof Vasu Reddy, UFS Deputy Vice-Chancellor: Research and Internationalisation, says: “This accolade speaks volumes of the calibre of our scholars and the recognition of our expertise in the agricultural domain. The UFS is exceptionally proud of Prof Truter’s drive, initiatives, vision and foresight. Under his leadership, we will augment and inflect even further our standing and position in the circular economy of agriculture. Reddy added: “We will not simply be the heartland but the growing soul and substance of what agriculture might become through research, implementation and impact. We are watching this space with deep curiosity.”

Researcher wins prize for her work to reduce environmental pollution

Josepha Zielke, a PhD student at the Institute for Groundwater Studies at the University of the Free State (UFS), received the prize for the best student presentation at the International Mine Water Association (IMWA) symposium in Leipzig, Germany, this year. Her paper was titled Fine Ash Leaching in Tailings Dams – An Impact on the Underlying Aquifers?
 
Zielke said: “It is an honour to receive this prize as a student. IMWA is a big association which allows you to establish a network with other scientists, to exchange opinions and ideas and to gain new inspiration for your own work. It was exciting and informative to hear about the research conducted around the world and to meet the researchers themselves.”
 
Born in Germany, Zielke always wanted to study overseas. During an exchange year in Grade 11, she visited South Africa. When she had to make a decision about in which country to complete her studies, South Africa was first choice as she was familiar with the people and the country.
 
Zielke joins leading institute on groundwater research in the country
She completed her BSc Hons in Geology at the Nelson Mandela Metropolitan University. After working for a year in exploration, she decided to focus her studies on water-related problems which  has been a growing issue, not only in South Africa, but in many places around the world. Zielke heard that the UFS Institute for Groundwater Studies was the leading institute on groundwater research in the country, and decided to join the university.
 
After completing her MSc research, An analysis of the geochemical weathering profile within a fine ash tailings dam, Mpumalanga, South Africa, Zielke started the research for her PhD project on groundwater pollution along a fault system in Mpumalanga.
 
Research adding value to the environment by reducing pollution
She explains the focus of her research: “Several production plants and mine waste facilities are located on or near these geological structures which could be a possible cause of ground and surface water pollution. With the aid of geophysical ground surveys (using electromagnetics and electrical resistivity tomography), aquifer and tracer tests, we are trying to determine where the pollution is coming from, how far it has been distributed and to model the potential risks.
 
“This research will add value to the environment by preventing or at least reducing pollution leaking into the environment. Industrial sites always have a negative footprint on the environment but at least we try and contain it by finding the cause of ground and surface water pollution. Thereafter we try and solve the pollution problem or at least mitigate the damage to prevent the spreading of ground and surface water pollution in the area.”
