Dr Martin Clark, chair of the local organising committee, is looking forward to welcoming delegates to the GeoCongress.

In just more than three weeks, the University of the Free State (UFS) will open its doors to delegates attending GeoCongress 2025, hosted in collaboration with the Geological Society of South Africa. From 23 to 27 June 2025, academics, industry professionals, and students will come together on the Bloemfontein Campus to share knowledge, discuss new research, and connect with peers in the geosciences.

This biennial event will feature a dynamic programme of workshops, keynote addresses, and presentations covering a broad range of topics in the field.

Message from the event organisers and UFS leadership

“It is a unique honour to be able to host the national GeoCongress, being responsible for bringing together our partners in industry and academia to share our evolving understanding of the rocks, minerals, and advances in the geosciences and associated disciplines. My view of the GeoCongress stems from my appreciation and understanding of one of South Africa’s most highly regarded geologists, Dr Hans Merensky. Dr Merensky is credited with finding platinum in the Bushveld, diamonds in Namaqualand, and phosphorus and vermiculite in Phalaborwa. However, less remember was Dr Merensky’s ability to coordinate comprehensive investigations of rocks, and his tenacity in exploring across the South African landscape. For this, I believe our theme Embracing Change through Collaboration is apt, since it's through interactions between various sectors that we are best able to handle the challenges of tomorrow,” comments Dr Martin Clark, Senior Lecturer in the UFS Department of Geology and principal investigator of the Merensky Group for Airborne Geological Image Classification (MAGIC) at the Department of Geology.

“The 2025 GeoCongress symbolises the principles of sustainable research and innovation that we advocate for in the Faculty of Natural and Agricultural Sciences and underscores our dedication to the development of interdisciplinary collaboration. Research collaboration through our Green and Complex Research Hubs is consistent with the congress theme of ‘Embracing Change Through Collaboration’. By integrating geoscience research with broader sustainability and technological advancements, we guarantee that our scientific discoveries make a significant contribution to both environmental stewardship and industry," said Prof Paul Oberholster, Dean of the Faculty of Natural and Agricultural Sciences.

Outstanding line-up of attendees

GeoCongress 2025 is set to bring together some of the most influential minds in geoscience, creating a space where leading academics, industry experts, and emerging researchers can exchange ideas and insights. Attendees will have the opportunity to engage with key figures shaping the field, including Prof Glen Nwaila, Director of the Wits Mining Institute and a leading authority in economic geology and geometallurgy at the University of the Witwatersrand; Prof John Carranza, a highly regarded researcher at the UFS; and Sifiso Siwela, Chairperson of the SAMCODES Standards Committee and past president of the Geological Society of South Africa.

Adding to the wealth of expertise, Dr Geoffrey Howarth, Senior Lecturer at the University of Cape Town and Head of the Electron Microprobe Facility, will bring his knowledge in mineral studies, while Prof Susan Webb, Associate Professor of Geophysics at the University of the Witwatersrand and acting co-director of the DSI-NRF Centre of Excellence for Integrated Mineral and Energy Resource Analysis (CIMERA), will share her insights into geophysical research. Dr Hayley Cawthra, specialist scientist at the Council for Geoscience, will contribute her expertise in coastal geology, and Prof Steve McCourt, President of the Geological Society of South Africa and Professor Emeritus at the University of KwaZulu-Natal, will bring his experience in structural geology. The line-up also includes Prof Wolfgang Maier from Cardiff University, whose research on magmatic ore deposits continues to influence the field.

To make the most of your GeoCongress 2025 experience, be sure to take full advantage of the networking opportunities – from informal meet-and-greets to engaging panel discussions. Don't miss the chance to attend hands-on workshops and exciting field excursions. These excursions offer a deeper look into the country’s rich geological history, with opportunities to visit Florisbad, Kimberley, the Beatrix operations in the Goldfields, or the Drakensberg. For more tips on navigating the congress and must-see highlights, visit the GeoCongress 2025 website at https://geocongress2025.org.za/ or contact us at secretariat@geocongress2025.org.za.

GeoCongress 2025 is set to be a landmark event on the geosciences calendar. With the UFS as your host, prepare for an experience that combines academic excellence, innovation, and a collaborative spirit. Welcome to GeoCongress 2025!

Farmers need to plan grazing better, says UFS expert

“Farmers should save veld during the summer months to have grazing available for animals especially in the winter and early spring. Farmers should also adjust livestock numbers timely and wisely according to the available material in the field,” says Prof HO de Waal, professional animal scientist and affiliated researcher in the Department of Animal, Wildlife and Grassland Sciences at the University of the Free State.

He offered this advice as a result of the sporadic and scattered (scant) rainfall of the past couple of summers. “In retrospect we know that this kind of precipitation started in about 2014 and has continued in subsequent summers. In February 2015, it was clear that a major fodder scarcity was developing.”

Existing research methods serve as source of current knowledge
Dr Herman Fouché (Agricultural Research Council) has conducted research on the impact of climate, especially rainfall, on the growth of grass. Sophisticated computer technology developed as far back as the 1980s to – through modelling – predicts the impact of climate on field production during the growing season.

The impact of climate, and more specifically rainfall, on field production has been known to animal and grazing scientists for a long time. Prof De Waal used the modelling results to determine the impact of rainfall on grass as a feeding source for animals.

“Information that emerged from this old research programme could therefore be applied directly to animal production,” says Prof De Waal.

Adjust livestock numbers to availability of grazing
In the summer rainfall areas of South Africa, grass usually grows from the end of August and early September. The growth process is dependent on the transfer of soil moisture, as well as on rainfall during the winter and early spring.

“Livestock numbers should be balanced throughout the year (according to the nutritional needs and production of the animals) with the availability of grazing material – be consistent, not only during certain seasons or when drought is imminent,” is Prof De Waal’s advice to farmers. “Farmers are also encouraged to carefully reduce the number of livestock on grazing and to rather focus their attention and limited resources on the remaining breeding herds (cows and ewes).”

“It is tragic, but unfortunately many farmers will not survive the effects of recent years. Similar climatic conditions will occur, with the same tragic consequences for man and beast. Better planning has to start now.” The assistance of private institutions, individuals, as well as the government, during the severe droughts is gratefully acknowledged.

Spineless cactus pear as solution for scarcity of animal feed
Prof De Waal says spineless cactus pears could be used as a feeding source during droughts. “The effects of a severe drought, or major animal-feed scarcity, are still prevalent in large parts of the subcontinent.” This may act as a catalyst to utilise spineless cactus pears as a feeding source and to be incorporated in the feed-flow programme for livestock on natural grazing.
