Island country

An island country, island state, or island nation is a country whose primary territory consists of one or more islands or parts of islands.^{[citation needed]} Approximately 25% of all independent countries are island countries. Island countries are historically more stable than many continental states but are vulnerable to conquest by naval superpowers. Indonesia is the largest and most populated island country in the world.

There are great variations between island country economies: they may rely mainly on extractive industries, such as mining, fishing and agriculture, and/or on services such as transit hubs, tourism, and financial services. Many islands have low-lying geographies and their economies and population centers develop along coast plains and ports; such states may be vulnerable to the effects of climate change, especially sea level rise.

Remote or significant islands and archipelagos that are not themselves sovereign are often known as dependencies or overseas territories.

History

Politics

Historically, island countries have tended to be less prone to political instability than their continental counterparts. The percentage of island countries that are democratic is higher than that of continental countries.

Island territories

While island countries by definition are sovereign states, there are also several islands and archipelagos around the world that operate semi-autonomously from their official sovereign states. These are often known as dependencies or overseas territories and can be similar in nature to proper island countries.

War

Island countries have often been the basis of maritime conquest and historical rivalry between other countries. Island countries are more susceptible to attack by large, continental countries due to their size and dependence on sea and air lines of communication. Many island countries are also vulnerable to predation by mercenaries and other foreign invaders, although their isolation also makes them a difficult target.

Natural resources

Many developing small island countries rely heavily on fish for their main supply of food. Some are turning to renewable energy—such as wind power, hydropower, geothermal power and biodiesel from copra oil—to defend against potential rises in oil prices.

Geography

Some island countries are more affected than other countries by climate change, which produces problems such as reduced land use, water scarcity, and sometimes even resettlement issues. Some low-lying island countries are slowly being submerged by the rising water levels of the Pacific Ocean. Climate change also impacts island countries by causing natural disasters such as tropical cyclones, hurricanes, flash floods and droughts.

Climate change

This section is an excerpt from Effects of climate change on small island countries.[edit]

The effects of climate change on small island countries are affecting people in coastal areas through sea level rise, increasing heavy rain events, tropical cyclones and storm surges.^: 2045 These effects of climate change threaten the existence of many island countries, their peoples and cultures. They also alter ecosystems and natural environments in those countries. Small island developing states (SIDS) are a heterogenous group of countries but many of them are particularly at risk to climate change. Those countries have been quite vocal in calling attention to the challenges they face from climate change. For example, the Maldives and nations of the Caribbean and Pacific Islands are already experiencing considerable impacts of climate change. It is critical for them to implement climate change adaptation measures fast.

Some small and low population islands do not have the resources to protect their islands and natural resources. They experience climate hazards which impact on human health, livelihoods, and inhabitable space. This can lead to pressure to leave these islands but resources to do so are often lacking as well.

Efforts to combat these challenges are ongoing and multinational. Many of the small island developing countries have a high vulnerability to climate change, whilst having contributed very little to global greenhouse gas emissions. Therefore, some small island countries have made advocacy for global cooperation on climate change mitigation a key aspect of their foreign policy.

Economics

Many island countries rely heavily on imports and are greatly affected by changes in the global economy. Due to the nature of island countries their economies are often characterised by being smaller, relatively isolated from world trade and economy, more vulnerable to shipping costs, and more likely to suffer environmental damage to infrastructure; exceptions include Japan, Taiwan^{[citation needed]} and the United Kingdom. The dominant industry for many island countries is tourism.

Composition

Island countries are typically small with low populations, although some, like Indonesia, Japan, and the Philippines are notable exceptions.

Some island countries are centred on one or two major islands, such as Bahrain, Cuba, Iceland, Malta, New Zealand, Singapore, Sri Lanka, Taiwan, Trinidad and Tobago, and the United Kingdom. Others are spread out over hundreds or thousands of smaller islands, such as The Bahamas, Indonesia, Japan, the Maldives, the Philippines, and Seychelles. Some island countries share one or more of their islands with other countries, such as Ireland and the United Kingdom; the Dominican Republic and Haiti; and Indonesia, which shares islands with Brunei, East Timor, Malaysia, and Papua New Guinea. Bahrain, Singapore, and the United Kingdom have fixed links such as bridges and tunnels to the continental landmass: Bahrain is linked to Saudi Arabia by the King Fahd Causeway, Singapore to Malaysia by the Johor–Singapore Causeway and Second Link, and the United Kingdom has a railway connection to France through the Channel Tunnel.

Geographically, the country of Australia is considered a continental landmass rather than an island, covering the largest landmass of the Australian continent. In the past, however, it was considered an island country for tourism purposes (among others) and is sometimes referred to as such.
