Drylands are vast and home to a wide array of biodiversity, while also hosting a large portion of the world’s farmland, but they face continued desertification, despite many of them recently experiencing increased vegetation levels. Five million hectares (12 million acres) of drylands, an area half the size of South Korea, have been desertified due to climate change since 1980, but elevated CO2 levels are also driving a regreening of some areas, which some argue is a positive effect of pumping CO2 into the atmosphere. However, our guest on this episode says this isn’t necessarily good news: remote-sensing researcher Arden Burrell describes how the CO2 fertilization effect is greening some dryland ecosystems, and why this worries scientists who say it may mask land overuse and decreased water resources.

Marine biologist and climate policy advocate Ayana Elizabeth Johnson joins this episode to discuss her latest book, What If We Get It Right? Visions of Climate Futures, a compilation of essays and interviews with experts and authors in the climate and environmental fields. Her book sensitively probes the problems human society faces and potential pathways to address environmental injustice, from the unsustainable industrialization of our food systems to the inequity (or lack) of climate policy in many places. Co-host Mike DiGirolamo speaks with Johnson about key insights from her book’s array of interviews, plus lessons learned from fighting for climate policy herself in the form of a “Blue New Deal.” Like this podcast?

The Phnom Chum Rok Sat community forest used to support local and Indigenous groups in Cambodia’s Stung Treng province, as well as a thriving local ecotourism venture, but that all changed this year when mining company Lin Vatey privately acquired roughly two-thirds of the land and began clearing the forest. Mongabay features writer Gerry Flynn investigated how this happened with freelance reporter Nehru Pry, and speaks with co-host Mike DiGirolamo about how the 10 individuals behind the land grab, many of whom have connections to powerful Cambodian military officials and their families, managed this land grab. Local community members who have resisted currently face legal intimidation and arrests. While community forests, such as Phnon Chum Rok Sat, are supposed to belong to the public, this kind of corporate acquisition of land is commonplace in the nation, Flynn says. “As we see a lot in Cambodia, it’s public forests being turned into private fortunes.” Like this podcast?

“Legal personhood” and laws regarding the “rights of nature” are being trialed in nations worldwide, but whether they lead to measurable conservation outcomes is yet to be seen, says environmental economist Viktoria Kahui. Still, she says on this episode of the Mongabay Newscast that she’s very hopeful about them. There’s a global debate surrounding these laws’ efficacy as a tool for conservation, and growing uneasiness about how they may impose a Western viewpoint upon something as inherently complex and extralegal as nature. Some critics argue that such a concept not only transcends the legal system but also cannot be subjected to it without harming the people and places these laws are intended to empower. Yet Kahui argues that there’s potential for rights-of-nature laws to develop in context-dependent scenarios, where humans can advocate on behalf of nature in places like Ecuador, which she says is a particularly powerful example.

Homeowners and towns along the U.S. East Coast are increasingly building “living shorelines” to adapt to sea level rise and boost wildlife habitat in a more economical and less carbon-intensive way than concrete seawalls. These projects protect shorelines using a clever mix of native plants, driftwood, holiday trees, and other organic materials. Peter Slovinsky, a coastal geologist with the Maine Geological Survey, joins the Mongabay Newscast to discuss the benefits of living shorelines, how they are implemented in his state, and what other techniques coastal communities should consider in a world with a warming climate and rising seas.

Apoorva Mandavilli, a science and health journalist for The New York Times, discusses the H5N1 bird flu outbreak, dubbed an 'existential threat' to biodiversity. She outlines how the virus is impacting wildlife and the potential risks to human health. Mandavilli highlights the role of environmental degradation and industrial agriculture in exacerbating this crisis. Furthermore, she critiques U.S. pandemic response measures and underscores the urgent need for improved monitoring and vaccination strategies to combat this adaptable virus.

Top National Geographic photographer Kiliii Yüyan joined the show to discuss traditional ecological knowledge (TEK) and why Indigenous communities are the world’s most effective conservationists. Yüyan spoke about this with us in March 2023 and we're sharing the episode again after it recently won a 'Best coverage of Indigenous communities' prize from the Indigenous Media Awards. While the National Geographic version of "Guardians of Life" is now published, the collaboration between Gleb Raygorodetsky and Yüyan will be published in book form in 2025.

The Reeds caught no fish in stark contrast to earlier times. Before California became a state, the river saw about 500,000 salmon each fall, but last year just 53,954 mature Chinook swam up, a 90 percent decline. The nation now restricts salmon fishing to Ishi Pishi Falls, but with the slated removal of four dams, the Karuk hope the salmon will return. Image (c) Kiliii Yuyan.

Mongabay newswire editor Shreya Dasgupta joins the Mongabay Newscast to detail her new three-part miniseries, Wild Frequencies, produced in collaboration with the Mongabay India bureau. Dasgupta details her journey with Mongabay-India senior digital editor Kartik Chandramouli. They travel the country speaking with researchers, listening and studying to the sounds produced by bats, Asian elephants, sarus cranes, wolves and many other animals. The emerging field for which this study is named, bioacoustics, is helping researchers lay foundational knowledge crucial for conservation measures.

Scientists described Batrachochytrium salamandrivorans (Bsal) over 10 years ago, a pathogen that causes the deadly disease chytridiomycosis which is currently devastating salamanders and frogs around the world, contributing to a global amphibian decline. But thanks to a successful cross border (U.S., Mexico & Canada) effort to keep it out, it has yet to arrive in North America: the Bsal Task Force is made up of scientists from each nation using education, outreach, science and policy to keep the disease from reaching the continent. Founding task force co-chair Deanna Olson of the U.S. Forest Service joins the podcast to discuss its successes, lessons learned that can help managers prevent other wildlife disease outbreaks, and the challenges that lie ahead.

U.S. states such as Vermont and Massachusetts are cutting thousands of acres of forest for solar power projects, despite the fact that this harms biodiversity and degrades ecosystems' carbon sequestration capacity. Journalist and author Judith Schwartz joins the Mongabay Newscast to speak with co-host Mike DiGirolamo about the seeming irony of cutting forests for renewable energy, and why she says states like hers are 'missing the plot' on climate action: she lives near a forest in southwestern Vermont where a company has proposed an 85-acre project that would export its electricity 100 miles south, to customers in Connecticut. A recent report found that such deforestation in nearby Massachusetts is unnecessary to meet that state's clean energy commitments, and would be better achieved by using already developed land like rooftops and parking lots, instead of farms or forests. Yet the acreage lost to solar energy projects in Massachusetts since 2010 has already released the equivalent of the annual emissions of more than 100,000 cars.
