Healing Mining Landscapes the Geomorphic Way: A Vision for Sustainable Mine Rehabilitation

The Critical Minerals Challenge Centre at the University of Exeter recently hosted a thought-provoking seminar by Professor José F. Martín Duque, a leading geomorphologist from the Complutense University of Madrid. The event, titled “Healing Mining Landscapes the Geomorphic Way,” explored innovative approaches to mine rehabilitation through geomorphic landform design.

The seminar focused on the critical differences between conventional landform design and geomorphic landscape design in mine rehabilitation. While traditional methods often result in artificial, geotechnically stable terrains that are susceptible to erosion, geomorphic design reshapes post-mining landscapes based on locally sourced, surface drainage data to mimic natural forms—enhancing ecological recovery, visual integration, and long-term stability. Professor Martín Duque emphasised that despite its clear advantages, this approach faces significant limitations due to a shortage of trained professionals and specialised tools.

Professor Martín Duque was joined by colleagues Harley Lacy, Greg Hancock, and Ann-Marie Hancock and the event was part of a broader UK tour of mining and Ann-Marie Hancock sites in Cornwall and Wales, coordinated by Pete Whitbread-Abrutat of Future Terrains, a leading advocate for sustainable post-mining landscapes and lead author of the recent book, 102 Things to Do with a Hole in the Ground.

Drawing on over three decades of international experience, Professor Martín Duque presented compelling case studies from Spain, the US, Australia, and Colombia. These examples demonstrated how geomorphic landform design can reduce erosion, restore natural drainage systems, and foster community acceptance of post-mining land uses.

As the world accelerates its transition to clean energy, the demand for critical minerals is surging. Professor Martín Duque stressed that geomorphic restoration offers a vital bridge between mining operations, environmental stewardship, and community engagement—especially in Europe, where sustainable extraction is a growing priority.
