It includes Australia, the smallest continent in terms of total land area. Most of Oceania is under the Pacific, a vast body of water that is larger than all the Earth’s continental landmasses and islands combined. The name “Oceania” justly establishes the Pacific Ocean as the defining characteristic of the continent. Oceania’s physical geography, environment and resources, and human geography can be considered separately. Oceania’s natural resources are best defined in connection with its island groups. The continental islands of Australia, New Zealand, and Papua New Guinea support rich natural- resource economies, while the other Pacific Islands rely on their natural resources for subsistence more than economic development. Climate and Agriculture In Australia and Oceania, an island’s overall land area, latitude, relation to different winds, and geographic isolation determine its climate. The continental islands of Australia, New Zealand, and to a lesser degree, Papua New Guinea, have a diversity of climates and agricultural products. Most high and low islands have tropical climates and limited agricultural products. Australia has the most diverse climate on the continent because of its large size and position on the Tropic of Capricorn, which runs through the middle of the country. Australia’s northern coast is tropical. This area is used principally for dairy and beef production. The country’s southern region has a Mediterranean climate. Wheat and other cereals, oilseeds, and legumes are mainly produced in this region. This area is also a major wine-producing region. Australia’s interior is mainly desert, surrounded by more temperate grasslands. Sheep ranching is common in grassland areas that flank the desert’s eastern and western edges. Australia is the world’s largest exporter of wool. New Zealand’s isolation from other continents and exposure to cold western winds and ocean currents gives it a much milder climate than Australia. This climate is suited to livestock grazing and ranching, including beef cattle, dairy cattle, domestic deer, and, most importantly, sheep. Sheep outnumber people by about 12 to 1 in New Zealand. The country is the world’s largest producer and exporter of crossbred wool, a rougher-textured material than regular wool. Much like Australia, New Zealand is becoming an important wine producer. Grapes are grown on the northern tip of the North Island and the south-central area of the South Island. Papua New Guinea lies in the warm equatorial region. Almost all of the country has a tropical wet climate. Its principal commercial crops are sweet potatoes, sugar cane, copra (dried coconut meat), coffee, cocoa, and rubber. About 85 percent of the population engages in subsistence agriculture, meaning they grow enough food to support themselves and their families. This is because Papua New Guinea is an extremely rural country, with many people living in isolated communities that have access to fertile lands but not centralized markets. The Pacific Islands lie in a warm equatorial band between the Tropic of Cancer and the Tropic of Capricorn. The tropical islands’ main agricultural products include banana, coconut, kava (a plant whose roots are made into a traditional beverage), and sugar cane. Much like Papua New Guinea, the people of the Pacific Islands practice mostly subsistence agriculture. Some of the few agricultural exports in the region are Tonga’s vanilla and squash, Samoa’s taro, and Fiji’s sugar products. Forestry and Fishing Forestry, the management of trees and other vegetation in forests, is an important economic activity in Australia and Oceania’s continental islands. Australia’s forest industries had a gross value of $1.7 billion in 2008. Its main forest products are sawn wood, wood-based panels, paper, and wood chips. Australia’s forest industry has benefitted from the development of tree plantations, which yield up to 14 times more wood per hectare than native forests. Plantations now supply more than two-thirds of harvested logs in Australia. Fast-growing trees such as eucalyptus and Monterey pine dominate these plantations. The lumber industry is also important to the economy of Papua New Guinea. The country has a unique forest-ownership program. Tribal clan groups own 95 percent of the total land area of the country. In order to carry out any forest-related operations, meetings must take place between government agencies and clan groups. The country’s main exported tree species are eucalyptus, rosewood, and pine. In the Pacific Islands, native forests are an important part of local economies, but commercial forestry is uncommon. The Solomon Islands is one of the few Pacific Island nations that support commercial forestry. Forestry accounts for roughly 70 percent of the country’s exports. But logging practices are intensive and unsustainable. The Solomon Islands have lost 21.5 percent of their forest cover between 1990 and 2005. It is estimated that the lumber industry will be completely gone by 2014-15 if the country does not enforce more strict environmental controls on forestry activities. The commercial fishing industry is an important contributor to economies throughout Australia and Oceania. About 600 marine and freshwater seafood species are sold in Australia for local and foreign consumption. “Wild-caught” seafood makes up about two-thirds of total seafood production. Rock lobster, pearls, abalone, and prawns make up $1.3 billion (86 percent) of total seafood exports. New Zealand’s main seafood exports are mussels, rock lobster, hoki (hake), squid, and salmon. New Zealand exports about 90 percent of its seafood to foreign countries. Fishing is a main economic contributor for the Maori, the aboriginal people of New Zealand. The Maori own about 50 percent of the country’s fishing quota. Papua New Guinea’s commercial fisheries support prawn, sea cucumber, tuna, lobster, shark, and other fish. Papua New Guinea also has a diverse range of small-scale and subsistence fisheries that support rural communities. The Pacific Islands support subsistence fisheries that are the livelihoods of many local peoples. A lack of infrastructure and investment, however, makes large-scale commercial fishing difficult. As a result, the fishing industry has poor earnings even though fish resources are abundant. For example, Pacific Island countries catch just $600 million worth of tuna, while foreign nations fishing in the same waters catch more than $2 billion worth. Regional and international organizations, such as the Pacific Islands Forum Fisheries Agency, are working to strengthen the fishing industry in the Pacific Islands. Environmental organizations are working to ensure the developing fishing industry is sustainable. They are also seeking to put limits or quotas on the amount of fish a vessel or organization can harvest. Mining and Drilling The continental islands of Australia, New Zealand, and New Guinea have important mineral and metal deposits. Australia is the world’s largest producer of opal and the world’s largest exporter of coal. The country is also one of the top producers of iron ore, nickel, gold, uranium, diamonds, and zinc. New Zealand is an important producer of coal, silver, iron ore, limestone, and gold. Papua New Guinea’s mineral deposits account for 72 percent of its export earnings, and mining is one of the country’s largest employers. Its main exports are copper, gold, and oil. The country’s waters will also be home to the world’s first offshore mining project. Using technology familiar to offshore oil drilling, a Canadian company will extract copper, gold, lead, silver, and zinc from deposits more than a mile beneath the ocean’s surface. Mining operations provide economic security to Papua New Guinea, while also contributing to environmental degradation. The Ok Tedi Mine, for example, produces copper and gold. It also produces 80,000 tons of waste rocks and 120,000 tons of toxic runoff that flows into the Ok Tedi River system. The fishery in the Ok Tedi River, as well as agricultural plots near the river’s bank, has been destroyed. The “Ok Tedi environmental disaster” has resulted in a lawsuit brought against the mining companies by thousands of Papua New Guineans who claim the environmental impact of the mine has ruined their livelihoods. One community, the Yonggom, won a $28.6 million settlement from the mining company, while another indigenous group, the Ningerum, is seeking $4 billion. The Ok Tedi Mine is scheduled to close in 2012. Most Pacific Islands have very limited mineral resources. New Caledonia contains about 10 percent of the world’s nickel reserves and is the world’s fifth-largest producer of the metal. Fiji’s second-largest export is gold (behind sugar cane) and the gold mining industry is a major employer in the country. Oil and natural gas resources are relatively low throughout Australia and Oceania. There are some offshore facilities surrounding Australia and New Zealand, although both of these developed countries consume more oil than they produce. Island nations in Australia and Oceania must import almost all their oil and gas, often across great distances. The cost of oil and gas is very high in the Pacific Islands, slowing the development process.
