Oceania: Our Sky. Our Land. Our Ocean. Our People.
Oceania is geographically one of IUCN’s largest regional programmes, covering over 100 million square kilometres of the Pacific Ocean. IUCN's Oceania region covers Australia, New Zealand and the 22 countries and territories of the Pacific Islands making up Melanesia, Micronesia and Polynesia.
The region stretches almost 12,000km from East to West and 6,000 km from North to South, with a combined Exclusive Economic Zone of close to 40 million square km. In contrast, the total land area is just over 8.5 million square km, with the larger islands of Australia (7 million square km), Papua New Guinea (463,000 square km) and New Zealand (268,000 square km) accounting for approximately 93% of this total land area.
The total human population is estimated at 35 million, with just over 22 million in Australia and 4 million in New Zealand. Approximately 9 million people inhabit the various Pacific Island countries and territories, with differences observed according to the size of the country: for example over 5 million people in the largest land mass of Papua New Guinea and populations under 2,000 in countries such as Niue and Tokelau. The Pitcairn Islands have less than 50 inhabitants. Each year as many as 3 million visitors to the region increase these figures.
IUCN Oceania Regional Office
The IUCN Oceania region is comprised of the 24 countries and territories of Polynesia, Micronesia, Melanesia, Australia and New Zealand. Oceania is geographically one of IUCN’s largest regional programmes, covering over 100 million km2 of land and ocean. Oceania also contains a diverse range of ecosystems, from coral reefs to kelp forests, mangroves to montane forests, and wetlands to deserts.
Throughout the Pacific, nature supports the daily livelihoods of island communities. Nature is both culturally significant and the primary source of food, water and income. However, increasing pressures from growing populations, extractive industries, infrastructure developments and invasive species are increasing the risk of biodiversity loss in many countries.
Australia and New Zealand lead the region’s economic development, and have solid capacity in the environmental management of developments. The countries and territories of the Pacific Islands have also made progress in recent years in building environmental governance and policy. IUCN often acts as a broker for the environment, encouraging governments, like-minded organizations and communities to work together for the sustainable management of nature’s resources.
