This December, Ian and Heather had a chance to present their research on mine tailings and agricultural carbon sequestration at a conference in Chile held by the International Institute for Environmental Sciences. It was a busy week of fascinating talks on environmental health and remediation, circular economies and Indigenous knowledge. We also had the opportunity to visit the province of Llanquihue, home to two active stratovolcanoes, a geologist's dream! Thank you, IIES, for providing funding and to our Chilean host universities for a wonderful conference!
