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.

From peasant to president; from Samora Machel to Cahora Bassa

When the plane crashed in Mbuzini, the entire country was submerged in a profound grieving.

This is how Prof Allen Isaacman, Regents Professor of History at the University of Minnesota, described the effect President Samora Machel’s death in 1986 had on Mozambique. In a public lecture, Prof Isaacman spoke about the man, Samora Machel, and the influences that shaped Machel’s life. The event, recently hosted by the UFS International Studies Group on the Bloemfontein Campus, was part of the Stanley Trapido Seminar Programme.

Samora Machel: from peasant to president
Born in 1933 into a peasant family, Machel was allowed to advance only to the third grade in school. “And yet,” Prof Isaacman said, “he became a very prominent local peasant intellectual and ultimately one of the most significant critics of Portuguese colonialism and colonial capitalism.” Machel had a great sense of human agency and firmly believed that one is not a mere victim of circumstances. “You were born into a world, but you can change it,” Prof Isaacman explained Machel’s conviction.

From herding cattle in Chokwe, to working as male nurse, Machel went on to become the leader of the Liberation Front of Mozambique (Frelimo) and ultimately the president of his country. To this day, not only does he “capture the imagination of the Mozambican people and South Africans, but is considered one the great leaders of that moment in African history,” Prof Isaacman concluded his lecture.

Displacement, and the Delusion of Development: Cahora Bassa and Its Legacies in Mozambique, 1965–2007
Later in the day, Profs Allen and Barbara Isaacman discussed their book: ‘Displacement, and the Delusion of Development: Cahora Bassa and Its Legacies in Mozambique, 1965–2007’ at the Archives for Contemporary Affairs. As authors of the book, they investigate the history and legacies of one of Africa's largest dams, Cahora Bassa, which was built in Mozambique by the Portuguese in the late 1960s and early 1970s.

The dam was constructed under conditions of war and inaugurated after independence by a government led by Frelimo. The dam has since operated continuously, although, for many years, much of its electricity was not exported or used because armed rebels had destroyed many high voltage power line pillars. Since the end of the armed conflict in 1992, power lines have been rebuilt, and Cahora Bassa has provided electricity again, primarily to South Africa, though increasingly to the national Mozambican grid as well.
