The Department of Geology in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) and the Geological Society of South Africa will co-host GeoCongress 2025, set to take place from 23 to 27 June 2025 on the UFS Bloemfontein Campus. This prestigious biennial academic event, themed: Embracing change through collaboration, will bring together leading academics, students, and industry experts from across South Africa to explore the latest advancements in geosciences.

The congress reflects the university's commitment to academic excellence, quality, and impact – core tenets of its UFS Vision 130. As a research-led, student-centred, and regionally engaged university, the UFS continues to transform itself to stay relevant within the dynamic and ever-changing international higher education sphere.

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, says “The university is proud to co-host this major gathering of established and emerging earth scientists from a variety of disciplines, who will present relevant, timely research topics to a wider audience. The theme underscores the centrality of geosciences to our aspirations as a university for the country and continent, directing us towards a collective sustainable future. We are excited by the ideas to be featured at this conference. More importantly, we are inspired by the prospect of further promoting real interaction and innovation between academia, industry, and society for impactful change.”

A platform for scientific excellence

It is fitting for the UFS to co-host this event, as geologists in the Department of Geology as well as in the province have made significant contributions across multiple fields, including economic geology, palaeontology, and geomorphology.

In the Department of Geology, for instance, researchers are exploring a wide range of topics, including magmatic processes in the platinum-group-bearing Bushveld Igneous Complex, AI-driven prospectivity modelling of global deposits, meteorite impact-related processes in the Vredefort impact structure, and geological and structural studies in the Namaqualand region.

In the Free State, known for its rich mineral resources, including gold, diamonds, and coal, geologists have played a big role in exploring and developing these resources, particularly in the Free State Goldfields, one of South Africa’s leading gold-producing areas. The province also boasts significant coal deposits, important for power generation. In palaeontology, geologists have helped uncover valuable fossil sites, including the Florisbad hominid site, offering insights into the history of life on earth. Additionally, their research in geomorphology, especially around the Florisbad area, has shed light on unique landscapes and depositional environments, including lunette dunes.

In agriculture, geologists have worked closely with farmers to ensure sustainable land use, providing important information on soil composition and erosion prevention. They have also played a key role in the study of groundwater resources, helping to identify and assess borehole sites for irrigation and domestic water supply, which is key to farming in the region. The Institute for Groundwater Studies (IGS) at the UFS is the only institute in South Africa dedicated to geohydrology. Founded in 1974 by Prof FDI Hodgson, the IGS is the oldest institute at the university and has produced more than 1 000 postgraduate students. The institute conducts research on a wide variety of water-related topics. Of special interest is its contribution to the mining and industrial sectors in terms of water management, minimisation of pollution, as well as understanding the nature and behaviour of South Africa's aquifers. The IGS provides a complete service to these industries through field investigations, the development of specialised field equipment, an accredited laboratory, and computer models for aquifer management.

Building on these contributions in the field, GeoCongress 2025 marks an important event on South Africa’s geoscience calendar, showcasing the latest scientific advancements, innovative research, and practical applications shaping the industry. With engaging academic sessions, dynamic workshops, and practical field excursions, the conference offers attendees the opportunity to participate in meaningful discussions, attend insightful presentations, and take part in excursions that bring theory to life.

Opportunities for networking and growth

GeoCongress 2025 is more than just an academic gathering – it is an opportunity for professional growth and networking. Participants will meet peers, mentors, and industry leaders, establishing connections that can lead to new research projects and collaborations.

There is plenty to look forward to at this year's conference. Here are the key dates and event highlights for GeoCongress 2025.

UFS Physics Research Chair receives more funding

A research project into low-energy lighting using phosphor materials for light emitting diodes (LEDs) at the Department of Physics at the University of the Free State (UFS) has received further recognition. 

The South African Research Chairs Initiative (SARChi) has awarded further funding for the Research Chair in Solid State Luminescent and Advanced Materials situated in the department. Prof Hendrik Swart, a Senior Research Professor in the Department of Physics, says this means that the Chair will carry on receiving funds from SARChi for another five years. The Initiative also awarded Prof Swart in 2012 for the research, which resulted in funding for equipment and among others, bursaries.    

Better light emission in LED’s
The research focuses on better light emission of phosphor powers in LEDs. It is also looking into improving LED displays in flat screens. The research into solar cells has shown that phosphors can also increase their efficiency by increasing the range of light frequencies, which convert into electricity. It also entails that glow-in-the-dark coatings absorb light during the day and emit it at night. 

Prof Swart says over the next five years the research will focus on developing and producing devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have.” In practical terms, it means they want a farmer’s water pump that works with solar energy to work better with less energy input.” 

Device that simulates sunlight
Prof Swart says the renewal of the Chair’s funding means the department can now get equipment to enhance its research   such as a solar simulator. The solar simulator uses white LEDs whose intensity output and wavelengths can be tuned. The output is measured in number of suns. It enables researchers to work in a laboratory with a device that simulates sunlight.     

According to Prof Swart the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field. 

About 10 postdoctoral researchers are working on the studies done by the Chair in collaboration with the Council for Scientific and Industrial Research. 

The Research Chair Initiative aims to improve the research capacity at public universities to produce high-quality postgraduate students, research and innovative outputs. The criterion for evaluating the department’s Chair includes aspects such as how much development has occurred over the past five years. The assessors look at features such as the number of students the research entity has trained and how many publications the research team has produced.
