Oceania Overview and Geography

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.
