Biodiversity, Subsistence Farming, and Welfare Challenges in Oceania
Papua New Guinea (PNG) is one of the most biologically diverse countries on Earth, home to an estimated 5–10% of the world's species despite covering less than 1% of its land area. From tree kangaroos and birds of paradise to saltwater crocodiles and over 800 orchid species, PNG's natural heritage is extraordinary. Yet animal welfare infrastructure is among the least developed in the Asia-Pacific region, with minimal legislation, sparse enforcement, and significant welfare challenges in both wildlife and agricultural sectors.
PNG's primary animal protection law is the Animal Protection Act (Chapter 197), enacted in 1952 during Australian colonial administration and barely amended since independence in 1975. The Act prohibits cruelty and unnecessary suffering to animals but contains no provisions for farm animal production systems, wildlife welfare, or transport standards. Penalties are so low as to function as no deterrent.
Wildlife is managed under the Conservation Areas Act (1978) and the Fauna (Protection and Control) Act (1966), administered by the PNG Conservation and Environment Protection Authority (CEPA). Wildlife trade regulation focuses primarily on CITES compliance for export but welfare provisions for captured animals are minimal.
PNG's wildlife faces severe pressure from habitat loss, bushmeat hunting, and the live animal trade. Welfare implications are profound across all three threats.
PNG's 42 species of birds of paradise are globally iconic and central to PNG culture. While large-scale commercial trade is prohibited under CITES, illegal capture for feathers and the live trade continues. Capture methods — including trapping and snaring — cause significant injury and mortality. Cultural use of plumes in traditional ceremonies is legally protected but creates complex welfare-culture intersections.
Several tree kangaroo species are endemic to PNG's highland forests. Hunting for subsistence is widespread and culturally embedded in many communities. PNG law permits customary hunting by traditional landowners, creating a legal carve-out that welfare advocates find challenging to engage with respectfully. Habitat fragmentation forces tree kangaroos into smaller patches where they are more vulnerable to hunting pressure.
PNG is the world's largest legal exporter of saltwater and New Guinea crocodile skins. Commercial crocodile farms, concentrated in Western and Sepik regions, raise animals for the luxury leather market. Welfare standards on farms vary enormously — while some operations funded by international buyers maintain basic space and husbandry requirements, smaller farms operate with minimal oversight. Slaughter methods often do not meet standards recommended by welfare scientists.
Most PNG citizens practice subsistence farming, keeping pigs, chickens, and sometimes cattle under traditional systems. Smallholder pig-keeping is nearly universal in highlands communities, where pigs hold enormous cultural and economic significance as markers of wealth and essential gifts in ceremonial exchange (bride price, compensation payments, and festivals).
Traditional pig management in PNG's highlands involves animals that are deeply integrated into human social life — pigs may be hand-raised, named, and treated with significant affection by women who are their primary caretakers. However, the same animals are slaughtered at festivals using methods that cause prolonged suffering, and pigs may be tethered for extended periods during ceremonial preparation. This dual status — beloved and exploited — creates complex welfare dynamics.
Port Moresby and Lae support small commercial poultry sectors supplying urban markets. Broiler operations use imported genetics and largely follow Australian or Indonesian production models with minimal welfare regulation. Battery cage systems for layers are in use without regulatory restriction.
Urban dog and cat populations in Port Moresby, Lae, and other cities present significant welfare challenges. Many dogs are kept loosely — neither fully owned nor stray — and receive minimal veterinary care. Dog bites are a significant public health concern, and periodic culling operations by municipal authorities are common. The RSPCA PNG has advocated for vaccination-based population management as a more humane alternative.
PNG's Coral Triangle waters support some of the world's most biodiverse marine ecosystems. Fishing is essential to coastal livelihoods, and welfare of fish in capture and processing operations has received no regulatory attention. The live reef fish trade — capturing fish using cyanide to stun them for transport to restaurants — causes severe welfare harm and environmental damage. PNG has nominally banned cyanide fishing, but enforcement in remote island communities is negligible.
PNG's over 800 distinct language groups and enormous cultural diversity mean that attitudes toward animals vary dramatically by region, community, and tradition. Animal welfare messaging that fails to engage respectfully with customary practices and traditional ecological knowledge will be rejected. Effective welfare advocacy in PNG must:
Papua New Guinea's extraordinary biodiversity makes the welfare of its animals a matter of global significance. The country faces acute challenges: outdated legislation, minimal enforcement capacity, and enormous cultural diversity that complicates uniform welfare standards. However, PNG's integration into global wildlife trade and fisheries export markets creates external leverage for welfare improvement, and the country's existing conservation programs provide platforms for welfare science integration. Sustained investment in veterinary capacity, legislation reform, and culturally sensitive welfare education could substantially reduce animal suffering in one of the world's most unique natural environments.
