Papua New Guinea is set to conduct a comprehensive national assessment of its biodiversity and ecosystem services for the first time in the country's history, joining a small but growing group of nations pioneering a new approach to economic planning that explicitly accounts for the value of nature. PNG's natural endowment is genuinely extraordinary. The country's tropical rainforest is the third largest in the world, hosting over 5% of the world's total biodiversity. Its marine territory contains coral reef ecosystems of global significance supporting the world's most diverse marine life. The biodiversity assessment will generate the data and analytical framework needed to make better investment and policy decisions — enabling the government to balance resource development with conservation and unlock new sources of conservation finance. UNDP Resident Representative Dirk Wagener emphasized that biodiversity "is the foundation that provides the services we need to survive — drinking water, breathable air, fertile soil, and abundant seas for food." The assessment is expected to take two years to complete and will inform Papua New Guinea's next national development plan, its climate commitments under the Paris Agreement, and its strategy for accessing international biodiversity funding.

Papua New Guinea's extraordinary coral reef ecosystems are being harnessed as a cornerstone of climate resilience through a groundbreaking UNDP programme. The Investing in Coral Reefs and Blue Economy programme is delivering measurable results across coastal communities that depend on healthy marine ecosystems for food security and livelihoods. Papua New Guinea is home to some of the most biodiverse coral reefs on the planet. The country's exclusive economic zone of 3.1 million square kilometers contains approximately 18% of the global tuna stock, making healthy marine ecosystems a fundamental economic and food security asset. The programme works at the community level, supporting local marine protected areas, sustainable fishing practices, mangrove restoration, and coral reef monitoring. Women's groups have been particularly active, leading mangrove replanting initiatives. UNDP officials note that the Coral Reefs programme offers a replicable model for climate adaptation finance, demonstrating that investing in natural systems can deliver returns far exceeding the costs of conventional grey infrastructure. The programme has attracted co-financing from several international climate funds. As climate change intensifies bleaching events and other threats to coral reef health, the programme's early intervention and community-based management approach is seen as critical to preserving these ecosystems for future generations.

An underwater volcano has been erupting in the Bismarck Sea off the northern coast of Papua New Guinea since May 8, sending dramatic white steam plumes up to 3,000 meters into the atmosphere and creating expansive rafts of floating pumice drifting across the surrounding Pacific waters. Scientists are closely monitoring the event, which could potentially result in the birth of a new volcanic island. The eruption began when seismometers first detected a swarm of small earthquakes beneath the Titan Ridge, a volcanic feature in the southwestern Pacific. Within days, NASA's Aqua and Terra satellites captured striking imagery of the volcanic plumes and tan-colored pumice rafts. Scientists from multiple international institutions noted that the current eruption site is approximately 16 kilometers from a 1972 underwater eruption in the same region, suggesting the Titan Ridge is a zone of sustained geological activity. Papua New Guinea sits on the Pacific Ring of Fire, one of the most seismically and volcanically active regions on Earth. Scientists say they are unable to predict how long the current eruption will last or whether it will ultimately produce a permanent new landmass. The event has drawn significant international attention and is being monitored around the clock by regional geological agencies, with drone flyovers and ship-based observations planned to gather more detailed data.
