2. Introduction to the Region
Oceania (The Pacific World)
Region covers one-third of the earth’s surface
Dominated by the world’s largest ocean, the Pacific
Subregions
Australia
New Zealand
Islands of the Mid-Pacific
Antarctica is also covered in this chapter
No permanent human inhabitants
Site of important scientific research
3.
4. 8.1.1 Major Divisions of the Region
Pacific Island Regions
Melanesia “Black Islands”
Micronesia “Tiny Islands”
Polynesia “Many Islands”
Typical Traits for a Pacific Island Country
Population of 100,000 to 150,000
Area of 250 to 1,000 square miles
Made up of a number of islands
Poor economically
Ex-colony of Britain, New Zealand, or Australia
Heavily dependent on foreign economic aid
7. 8.1.2 The People and Where They Live
Regional population is 37 million
Australia has 23 million people
Papua New Guinea has 7 million people
Nauru only has 9,300 people
Population Growth Rates Vary Widely
Australia (0.7%) and New Zealand (0.8%)
2.6% in Papua New Guinea
Oceania is 76% rural, excluding Australia and N.Z.
People Overpopulation in Polynesia
Significant Emigration
Postindustrial Fear in Australia / New Zealand
Might not have enough people to support the
countries’ economies and aging populations
12. 8.2.1 Climates and Biomes
Most of the region is tropical
Cool mid-latitude westerly winds bring New Zealand and
coastal southern Australia a marine west coast climate
Coastal southern Australia has some Mediterranean
Coastal northern Australia has tropical savanna
Interior of Australia has desert climate and vegetation
15. 8.2.2 Island Types
Continental Islands
Continents or were attached to continents before sea level
changes and tectonic activities isolated them
Examples: Australia, New Guinea, New Britain, New Zealand
High Islands
Often the result of volcanic eruptions
Examples: Hawaii, Samoa, Society Islands
Low Islands
Made of coral
Most take the shape of an irregular ring surrounding a lagoon
(called an atoll)
Lack resources to support dense populations
Examples: Kiribati, Caroline and Marshall Islands
19. Geologic Hot Spot: Hawaii
Some of the volcanic high islands of the Pacific comprise
island chains. These are formed when the oceanic crust
slides over a stationary geologic hot spot in the earth’s
mantle where molten magma is relatively close to the crust.
As the crust slides over the geologic hot spot, magma rises
through the crust to form new volcanic islands.
22. 8.2.3 Vulnerability of Oceania’s Ecosystems
Factors Threatening Endemic Species
Human-Induced Extinctions
Habitat Destruction
Deliberate Hunting
Introduction of Exotic Species
Volcanic Eruptions
Typhoons (Hurricanes)
Rises in Sea Level
Hawaii as “Extinction Capital of the World”
Commercial logging on island of New Guinea
Home of 22,000 plant species, of which 90% are endemic
24. 8.3 Cultural and Historical Geographies
Australia & New Zealand
Mainly European in culture and ethnicity
Fiji, New Caledonia & Guam
Half Indigenous & Half Foreign
Rest of Oceania’s Population
80% Indigenous
80% of these are Melanesian
14% of these are Polynesian
6% of these are Micronesian
13% Asian
7% European
25. 8.3.1 The Indigenous Peoples of Oceania
Settlement began in Pacific region 50,000 years ago
Settlers came across land bridge that linked New Guinea
and Australia (Torres Strait Islanders)
Ancestors of today’s Aborigines
Languages
Linguistic Legacy
Aboriginal, Austronesian, and Papuan
Linguistic Complexity
Papua New Guinea is home to 860 languages
Vanuatu has 105 identified languages
Lingua Franca
English and French reflect colonial past
Pidgin is official language of Papua New Guinea
27. 8.3.2 Europeans in Oceania
First Europeans in region were voyagers
European legacy
Established trade
Introduced Christianity
Created new settlement patterns
Disrupted old political systems
Rearranged demographic and natural landscapes
Introduction of exotic crops
28.
29. 8.4 Economic Geography
Aside from Australia and New Zealand, the region is
characterized by a lack of industrial development
Poverty typical of LDCs prevails in the region
Tyrannies of size and distance
Most countries must import more than they can export
30. 8.4.1 Making a Living in Oceania
7 Major Economic Enterprises
Exports of Plantation Crops
Exports of Fish
Exports of Minerals
Services for Western Military Interests
Information Technology
Textile Production
Tourism
31. Nauru
The 10 square miles of land that is Nauru have been
devastated by phosphate mining that once made Nauruans
among the wealthiest people per capita on earth.
32. 8.5 Geopolitical Issues
Oceania was once entirely colonial
The U.S., Britain, Australia, and New Zealand have
abandoned most of their colonies
Only France has held on to all of its colonies
33. 8.5.1 Interest of Foreign Powers in the Pacific
Importance of islands to governing powers
Military Advantages
Economic Advantages
French Polynesia used for French atomic testing
Guam and American Samoa useful for U.S. military
purposes
Guam as a power projection hub, as it is five days’
sailing time closer to Asia than Hawaii is
Australia-United States Free Trade Agreement
34. 8.5.2 Oceania’s Environmental Future
Rise in sea level due to global warming
Sea levels have risen in recent years at a rate of 0.1” / yr
Unprecedented tidal surges
Kiribati, Marshall Islands, and Tuvalu could be completely
submerged, while other island nations would lose territory
Alliance of Small Island States
Politicked unsuccessfully at 1997 Kyoto Conference for
lowering of global greenhouse gas emissions to 20 percent
below their 1990 levels by 2005
Took legal recourse against U.S. and Australia
for failing to ratify the Kyoto Protocol
35. 8.6.1 Australia and New Zealand
Similar in population, cultural heritage, political problems and
orientation, type of economy, and location
Products of British colonization and reflect British heritage
Prosperous countries
Relatively few people among whom to spread wealth
Both owe their prosperity to wholesale transplantation of business
culture and technology from the UK
Despite their independence, remain loyal to Britain
(Australia in 1901 and New Zealand in 1907)
Belong to the British Commonwealth of Nations
Political Orientation
Since WWII, these two countries have sought closer relations with
the U.S., and British influence has waned
Seeking stronger roles in the Pacific Basin’s economy
Debate over whether Australians should convert the country into a
republic, ending formal ties with Britain
37. 8.6.2 Australia’s Aborigines
Aborigines (Australia’s indigenous inhabitants)
Believed their ancestors ‘sang’ the world into existence
Population
An estimated 300,000 to 1 million Aborigines inhabited Australia when
Europeans arrived in the 17th century
Colonizing whites slaughtered many and drove the rest into marginal
areas of the continent
Today, there are an estimated 510,000 Aborigines, living mainly in the
tropical north of the country
Aborigines suffer from:
High infant mortality rate
High unemployment
Low life expectancy
Contention between Aborigines & white majority over land rights
Aborigines increasingly enlisting aid of geographers and other social
scientists to document, measure & analyze traditional land claims
38. 8.6.3 Exotic Species on the Island Continent
Exotic species are nonnative plants and animals
introduced into an ecosystem
Impact is often catastrophic to native species
Islands are very sensitive to ecological disruption
Exotic species that have caused problems in Australia include:
Rabbits
Foxes
Mice
Water buffalo
Cane toads
Prickly pear cactus
Sheep
Cattle
Dromedary camels
The Rabbit War Must Be
Won!
39. 8.6.4 Antarctica
World’s 5th largest continent (ranks as the windiest and driest)
Human drama in exploration, bravery, and foolhardiness
Climate
Summers include “whiteouts” caused by light refraction on snow and
ice covering about 95% of the continent
Winters are mainly dark, with average temperatures the coldest in
the world
The “Ozone Hole” is concentrated seasonally over Antarctica
Important locale for scientific research
Virtually no human settlement beyond research teams
Public, economic, and geopolitical interests are increasing
Several countries claim areas of the continent
These claims put on hold since 1961 due to the Antarctic Treaty
Forbids any exploitation of Antarctica’s natural resources until 2048
