Mongabay Explores

Leif Cocks returns to the podcast to discuss the status of the Sumatran elephant, a critically endangered species that we discussed with him in season 2, which is estimated to have less than 10 years to find a conservation solution or face extinction: he says the ranks of passionate, young Indonesian conservationists he's recently met that are working for the iconic animals' future gives him great hope.

He also shares an update on the critically endangered Tapanuli orangutan, whose land is threatened by a controversial hydroelectric project in North Sumatra, which has also claimed the lives of 16 workers in less than two years.

By 2025 the global, edible nut industry will be worth an estimated $2 billion. In Papua New Guinea (PNG), the traditional and plentiful staple, the galip nut (Canarium indicum), holds promise of tapping into that demand. Its relative ease of access for smallholder (non-commercial) farms means a new source of income for thousands of farmers across PNG.

On this episode of Mongabay Explores, we speak with Dorothy Devine Luana, an entrepreneur from the province of East New Britain, whose company grows galip nuts using agroforestry, a farming technique rooted in traditional knowledge that grows multiple cash crops alongside woody perennials.

We also speak with Nora Devoe, research program manager for a special project focused on the galip nut at the Australian Centre for International Agricultural Research (ACIAR). This project has been funding more than a decade of research seeking to understand the viability and potential of the galip nut to drive the canarium industry in PNG and foster new markets for entrepreneurs and locals like Dorothy to sell the crop.

The Tanah Merah project sits in the heart of New Guinea covering 2,800 square kilometers (1,100 square miles). Roughly twice the size of Greater London, it threatens not only dense, primary, tropical rainforest and Indigenous land, but also could release as much carbon as the U.S. state of Virginia emits by burning fossil fuels for an entire year. However, the true owners of the project have been hidden by a web of corporate secrecy for more than a decade.

We speak with Philip Jacobson, senior editor at Mongabay, and Bonnie Sumner, investigative reporter at the Aotearoa New Zealand news outlet Newsroom, to discuss the project from inception to present day, the involvement of a New Zealand businessman, and where the project could go next.

New Guinea's dense tropical montane forests are home to 12 of 14 tree kangaroo species. Over the past couple of decades, conservationists have leveraged these charismatic, intelligent marsupials to spearhead community development, conservation efforts, and the establishment of protected areas. In Papua New Guinea, the Torricelli mountain range is home to three species of tree kangaroo, including the critically endangered tenkile. This mountain range sits in the crosshairs of a road project threatening to encroach upon the region; however, the government is in the process of reviewing a draft proposal to have it officially declared a protected area.

For this episode of the podcast, we speak with Jim Thomas of the Tenkile Conservation Alliance and Lisa Dabek and Modi Pontio of the Tree Kangaroo Conservation Program. They detail the successes and challenges of working for nearly two decades in PNG to conserve these intelligent marsupials and the lands they inhabit.

Spanning over 4,000 kilometers (2,500 miles) and being built over the course of decades, the Trans-Papua Highway cuts across the entire length of Indonesian New Guinea's two provinces, including 7 key protected areas.

While the project is nearly complete, experts warn it will cost billions annually to maintain, and threaten to open up untouched rainforest to palm oil expansion contributing an additional 4.5 million hectares of deforestation by 2036.

For this episode, we interviewed David Gaveau, founder of The TreeMap and Bill Laurance, distinguished professor, and director of the Center for Tropical, Environmental, and Sustainability Science at James Cook University in Australia.

Both experts explained the environmental, financial, and social costs of the project, which runs through Indonesia's Lorentz National Park, a UNESCO World Heritage Site.

New Guinea is home to the third-largest tropical rainforest in the world—of which 80% is still intact. The two-nation island also contains 44 species of unique birds-of-paradise and dense biodiverse regions unlike anywhere else on the planet.

Because of its one-of-a-kind biodiversity, and relatively undeveloped landscape, New Guinea is in a unique position to conserve its forest cover as part of an economy that serves its local inhabitants, rather than extracting from and deforesting these communities.

For this third episode of the New Guinea season, Mongabay interviews Bustar Maitar, CEO of EcoNusa, and biologist Edwin Scholes from the Cornell Lab of Ornithology about the diverse and charismatic birds-of-paradise and the potential for New Guinea to harness ecotourism to power a sustainable economy.

Since 2014, Papua New Guinea has been the world's largest tropical timber exporter: more than 70% of that is considered illegal. Timber companies continue to possess land originally owned by local Indigenous communities through legal loopholes: while the carbon market has gained popularity as an alternative source of revenue for Indigenous communities, it suffers from some of the same land rights abuses as timber extraction.

For this episode of Mongabay Explores we interview Gary Juffa, governor of Oro province in Papua New Guinea, and investigative journalist, Rachel Donald.

New Guinea is one of the most most biodiverse regions on the planet and also the world's largest tropical island. It makes up less than 0.5% of the world's landmass, but is estimated to contain as much as 10% of global biodiversity.

To unpack the vast biodiversity of New Guinea, conservation policy, and NGO efforts to protect land, culture and Indigenous rights, we spoke with Rodrigo Cámara-Leret, of the Department of Evolutionary Biology and Environmental Studies at the University of Zurich, Charlie Danny Heatubun, head of the research and development agency of the provincial government of West Papua, and Miriam Supuma of Synchronicity Earth.

In this third season of the podcast, we take a look at what makes New Guinea unlike any other place in this world, the contributing environmental impacts that threaten its culture and biodiversity, and what is being done to protect it.

'I'm amazed how resilient, adaptable and optimistic the people of Sumatra are,' conservationist and HAkA Sumatra founder Farwiza Farhan says in the first moments of this episode about the women and communities she works with during the final episode of Mongabay's special series on Sumatra.

The giant Indonesian island of course faces many environmental challenges, but there is also tremendous hope and good progress thanks to the work of people like her and educator Pungky Nanda Pratama, who also joins the show to describe how his Jungle Library Project & Sumatra Camera Trap Project are opening the eyes of the next generation to the need for protecting their fabulous natural heritage.

Host Mike DiGirolamo shares the effectiveness of their efforts, what they are hopeful for, their biggest challenges, and the role of grassroots organizing in protecting and revitalizing the land, wildlife, and people of Sumatra.

More about these guests' work:
