Theonila Roka Matbob grew up next to what was — at the time — the world’s largest open-pit mine in Bougainville, an autonomous region in Papua New Guinea, operated by a subsidiary of Rio Tinto. This mine wrought environmental and social devastation on the community of Panguna for decades. And many of these impacts carry on today, says Roka Matbob, who is an Indigenous Nasioi woman and politician. With the help of Jubilee Australia and the Human Rights Law Centre, Roka Matbob was able to file a legal complaint with Australia’s National Contact Point for Responsible Business Conduct. As a result, Rio Tinto signed a memorandum of understanding with the Bougainville government to remediate the impacts of this mine. For this legal achievement, Roka Matbob was awarded the Goldman Environmental Prize. However, she is skeptical that remediation for these impacts will occur. She joins the podcast this week to tell the Bougainville story and what she wants people to understand about mining’s impacts on the autonomous region and her community. “ The Bougainville story is a result of Australia’s political decision through Papua New Guinea government now implemented on Bougainville and leaving behind a toxic legacy that is already been kind of fenced out, not to have a forum to talk about,” she says. “So my intention is for us to start telling this story.” Late last year, the Bougainville government signed another memorandum of understanding with an Indian metals company, Loyd’s Metals, to redevelop the Panguna mine. Roka Matbob says…This article was originally published on Mongabay

Katharine Wilkinson has a Ph.D. in geography and the environment, is well known for being a co-author of the book Drawdown and co-founder of The All We Can Save Project. She joins the Newscast this week to discuss her latest book Climate Wayfinding: Healing Ourselves and the Planet We Call Home. As a journalist, it’s unhelpful for me to divorce myself from the topic of this interview, as I have experienced, time and again, the sense of “murky overwhelm” this book is specifically designed to address. But Wilkinson didn’t just write this book for journalists like myself who cover ecological crises for a living. She wrote it for readers and listeners like you. “I think we’re all in our own ways grappling with this increasingly mapless time, right? And that is quite literally true,” Wilkinson says. “‘Is there hope?’ and ‘What can I do?’ I think these are fundamentally navigational questions as much as they are questions of action.” What Climate Wayfinding does that I think is unique is it directly addresses the reader and takes them through a process of self-examination. Of sitting with the uncomfortable emotions one feels about our ecological crises, without judgment. And from that self-compassion, asking the reader to imagine the world they want to see instead and encouraging them to map out how they see themselves working to achieve it. It sounds relatively simple, but the work is real and, from my own experience, not unlike therapy. In my opinion, it’s a brave piece…This article was originally published on Mongabay

A group of 57 nations mostly from the Global South, describing themselves as “coalition of the willing” intent on making the Transition Away From Fossil Fuels, or TAFF, convened in the Colombian city of Santa Marta, from April 24-29, 2026, for the inaugural TAFF summit. Also referred to as the “Santa Marta Coalition,” this group of countries met to discuss and develop frameworks and pathways for nations to phase out fossil fuel dependency. Joining the Mongabay Newscast this week is Mamphela Ramphele, a medical doctor, activist and member of the Planetary Guardians, a network of experts advocating for the planetary boundaries as a measurement framework. Ramphele explains the highlights of the conference, which included the unveiling of a dedicated scientific panel to advise nations on developing road maps to transition off fossil fuels. The science panel includes experts such as Carlos Nobre from Brazil and Johan Rockström from Sweden, who pioneered the planetary boundaries concept. The conference also saw the establishment of “workstreams” to help nations connect their phaseout road maps to their emissions reduction targets as part of their U.N. climate commitments; leverage support to change their financial systems for the transition; and reform trade systems. Two nations in attendance, Colombia and France, announced their own phaseout road maps at the conference. Ramphele, from South Africa, suggests that as countries in the Santa Marta Coalition develop and implement their own road maps, other nations not yet on board will eventually be pressured to follow. Until a legally binding agreement, such…This article was originally published on Mongabay
