Environmental issues in Papua New Guinea Papua New Guinea faces extensive environmental challenges driven by land use, resource extraction, and climate hazards that affect ecosystems, communities, and infrastructure across the island of New Guinea and offshore territories. Pressures from international corporations, domestic stakeholders, and historical developments shape outcomes for forests, rivers, coral reefs, and cultural landscapes from the Highlands to the Autonomous Region of Bougainville. Responses involve national agencies, customary landowners, regional organizations, and international agreements.
Papua New Guinea's environmental profile intersects with New Guinea, the Australasian realm, and institutions such as the United Nations Environment Programme and Convention on Biological Diversity; its legislative framework includes the Environment Act 2000 and actors like the Conservation and Environment Protection Authority. Key drivers include commodity markets linked to APEC, investment by firms from Australia, China, and Canada, and customary land tenure systems recognized under the Papua New Guinea Constitution. International funding from entities like the World Bank, Asian Development Bank, and NGOs such as WWF, Conservation International, and The Nature Conservancy interacts with provincial administrations including Western Highlands Province and Morobe Province.
Deforestation in Papua New Guinea involves logging concessions awarded to companies including subsidiaries of firms historically tied to Rimbunan Hijau and Niugini. Clearance of lowland and montane rainforest affects regions near Sepik River, Fly River, and the Papuan Peninsula, with implications for carbon stocks measured under REDD+ and monitored by satellite programs like Global Forest Watch. Conflicts over timber licensing have produced disputes involving the Landowners Association, provincial governments such as East Sepik Province, and international advocacy from Greenpeace and Amnesty International. Illegal logging and conversion for oil palm plantations influence trade routes to markets such as Malaysia, Indonesia, and Singapore, and engage certification schemes like the Forest Stewardship Council.
Large-scale projects such as the Ok Tedi Mine, the Porgera Gold Mine, the Lihir Gold Mine, and legacy operations on Bougainville have generated tailings, acid mine drainage, and social unrest involving groups like the Bougainville Revolutionary Army and national actors including the Minerals Resources Authority. Gas and petroleum developments at Hides and liquefied natural gas projects linked to companies such as ExxonMobil and Shell raise concerns about coastal infrastructure near Gulf Province and environmental impact assessments under the Environmental Planning Act. Litigation and campaigns led by community organizations, law firms, and international courts mirror precedents in cases involving Rio Tinto and other multinational extractors.
Papua New Guinea hosts endemic taxa such as the Bird-of-paradise, species protected in areas like Kokoda Track, and mammals cataloged by institutions including the American Museum of Natural History and CSIRO. Habitat fragmentation threatens species listed under the IUCN Red List of Threatened Species, with local surveys by universities such as the University of Papua New Guinea and international collaborations with Smithsonian Institution and Royal Botanic Gardens, Kew. Hunting pressure and invasive species affect fauna across the New Guinea Highlands and islands like New Ireland and New Britain, intersecting with customary practices governed by clan systems and national wildlife regulations like the Fauna (Protection and Control) Act.
Riverine and coastal pollution stems from mining discharges in the Fly River basin, sedimentation from logging in the Purari River catchment, and municipal effluents in Port Moresby and towns such as Lae. Coral reef degradation affects areas within the Coral Triangle and marine provinces including Milne Bay Province and is documented by researchers from James Cook University and the University of the South Pacific. Overfishing by vessels from neighboring states, incidents involving flags of convenience, and coral bleaching events tied to research by the Intergovernmental Panel on Climate Change exacerbate declines in fisheries governed under regional bodies like the Pacific Islands Forum and Western and Central Pacific Fisheries Commission.
Papua New Guinea is vulnerable to sea-level rise impacting atolls in the Autonomous Region of Bougainville and coastal communities in Manus Province and East New Britain Province, with monitoring supported by the Pacific Climate Change Science Program and the Secretariat of the Pacific Regional Environment Programme. Extreme weather linked to El Niño–Southern Oscillation and tropical cyclones such as Cyclone Pam influences agriculture in the Markham Valley and infrastructure resilience projects financed by the Green Climate Fund and bilateral partners like Australia and Japan. National adaptation planning engages the Department of Climate Change and Development Authority and aligns with multilateral frameworks including the Paris Agreement.
Conservation initiatives combine protected areas like Kokoda Track, community-conserved areas on Manus Island, and partnerships with NGOs such as BirdLife International and Wildlife Conservation Society. Governance involves customary landowning institutions, provincial administrations such as Oro Province, and national law enforcement including the Royal Papua New Guinea Constabulary in enforcement roles. Multilateral programs from UNDP, bilateral aid from AusAID, and research collaborations with universities including Australian National University bolster capacity for sustainable management, biodiversity inventories, and climate adaptation planning. Continued tensions among resource developers, landowners, and conservationists shape policy debates involving parliamentary committees and international arbitration bodies.
