Oceania Overview and Geography

Study Notes

Oceania Overview

Oceania encompasses one-third of Earth's surface, primarily within the Pacific Ocean.
It comprises Australasia (Australia, New Zealand, and islands), Melanesia, Micronesia, and Polynesia.
Pacific Island countries generally have small populations, economic challenges, and rely on foreign aid.

Major Divisions

Melanesia ("Black Islands"), Micronesia ("Tiny Islands"), and Polynesia ("Many Islands").
Diverse island types exist – continental, high, and low islands.

Population

Oceania's population was approximately 40 million in 2016; Australia had the largest population (24 million).
A substantial portion (76%) of the population in Oceania is rural, excluding Australia and New Zealand.
Population growth rates vary across the region.

Climates and Biomes

Climate spans a wide range from deserts to temperate areas across the region, mainly reflecting location and altitude.
Biomes include savannas, steppes, deserts, and tropical rainforests representing varied environments.

Land Use

Livestock grazing, particularly in Australia, is a significant land use.
Agriculture, forestry, and mining are concentrated in resource-rich zones.
Urban development mostly occurs along coastlines.

Cultural and Historical Geographies

Australia and New Zealand have a majority European heritage with an indigenous population.
Other regions have diverse ethnicities, including indigenous, Asian, and European influences.
Rich linguistic and cultural diversity exists particularly in Papua New Guinea and Australia.

Economic Geography

Regional industrial development is limited, characterized by poverty levels typical of developing nations (LDCs).
The economy primarily revolves around exports of crops, fish, minerals, services, and growing sectors like IT, textiles, and tourism.
Phosphate mining significantly impacted Nauru's economy previously.

Geopolitical Issues

Most of Oceania's islands were formerly colonized; independence movements led to a majority of islands becoming independent nations.
Islands remain of military and economic importance to various governing powers.

Environmental Future

Rising sea levels due to global warming pose a critical threat to low-lying island nations.
The Alliance of Small Island States addresses these challenges.

Australia and New Zealand Relations

Australia and New Zealand share similarities in population, cultural heritage, and economic orientation.
They are prosperous nations with strong ties to the UK; however, relations with the U.S. are also significant.

Indigenous People

Indigenous Australians face challenges such as high infant mortality, unemployment, and low life expectancy.
Land rights disputes continue, with efforts focused on documenting traditional land claims.

Exotic Species

Introduced species in Australia have disrupted ecosystems, negatively impacting native species and environments.
