West Asia

West Asia, also called Western Asia or Southwest Asia, is the westernmost region of Asia. As defined by most academics, UN bodies and other institutions, the subregion consists of Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian highlands, the Levant, the island of Cyprus, the Sinai Peninsula and the South Caucasus. The region is separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea. West Asia contains the majority of the similarly defined Middle East. The Middle East is a political term that has changed many times depending on political and historical context while West Asia is a geographical term with more consistency. It excludes most of Egypt and the northwestern part of Turkey, and includes the southern part of the Caucasus.

West Asia covers an area of 5994935 km2, with a population of about 313 million. Of the 20 UN member countries fully or partly within the region, 13 are part of the Arab world. The most populous countries in West Asia are Iran, Turkey, Iraq, Saudi Arabia and Yemen.

In the World Geographical Scheme for Recording Plant Distributions (WGSRPD), West Asia excludes the Arabian Peninsula and includes Afghanistan. The Food and Agriculture Organization (FAO) excludes Egypt and includes Afghanistan. The United Nations Environment Programme excludes Cyprus, Israel, Turkey, and Iran from West Asia.

Definition
The term West Asia is used pragmatically and has no "correct" or generally accepted definition. Its typical definitions overlap substantially, but not entirely, with definitions of the terms Middle East, Eastern Mediterranean, and Near East (which is historically familiar but widely deprecated today). The National Geographic Style Manual as well as Maddison's The World Economy: Historical Statistics (2003) by the Organisation for Economic Co-operation and Development (OECD) include only Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Palestine (called West Bank and Gaza in the latter), Saudi Arabia, Syria, Turkey, UAE, and Yemen as West Asian countries. By contrast, the United Nations Industrial Development Organization (UNIDO) in its 2015 yearbook includes Armenia and Azerbaijan, and excludes Israel (as Other) and Turkey (as Europe).

Unlike the UNIDO, the United Nations Statistics Division (UNSD) excludes Iran from West Asia and includes Turkey, Georgia, and Cyprus in the region. In the United Nations geopolitical Eastern European Group, Armenia and Georgia are included in Eastern Europe, whereas Cyprus and East Thracian Turkey are in Southern Europe. These three nations are listed in the European category of the United Nations Educational, Scientific, and Cultural Organisation (UNESCO).

National members of West Asian sports governing bodies are limited to Bahrain, Iran, Iraq, Jordan, Kuwait, Lebanon, Syria, Oman, Palestine, Qatar, Saudi Arabia, United Arab Emirates, and Yemen. The Olympic Council of Asia's multi-sport event West Asian Games are contested by athletes representing these 13 countries. Among the region's sports organisations are the West Asia Basketball Association, West Asian Billiards and Snooker Federation, West Asian Football Federation, and the West Asian Tennis Federation.

History
"Western Asia" was in use as a geographical term in the early 19th century, before "Near East" became current as a geopolitical concept. In the context of the history of classical antiquity, "Western Asia" could mean the part of Asia known in classical antiquity, as opposed to the reaches of "interior Asia", i.e. Scythia, and "Eastern Asia" the easternmost reaches of geographical knowledge in classical authors, i.e. Transoxania and India. In the 20th century, "Western Asia" was used to denote a rough geographical era in the fields of archaeology and ancient history, especially as a shorthand for "the Fertile Crescent excluding Ancient Egypt" for the purposes of comparing the early civilizations of Egypt and the former.

Use of the term in the context of contemporary geopolitics or world economy appears to date from at least the mid-1960s.

Geography
The region is surrounded by eight major seas; the Aegean Sea, the Black Sea, the Caspian Sea, the Persian Gulf, the Arabian Sea, the Gulf of Aden, the Red Sea, and the Mediterranean Sea.

To the northwest and north, the region is delimited from Europe by the Turkish Straits and drainage divide of the Greater Caucasus, to the southwest, it is delimited from Africa by the Isthmus of Suez, while to the northeast and east, the region adjoins Central Asia and South Asia. The region is located east of Southern Europe and south of Eastern Europe.

The Dasht-e Kavir and Dasht-e Lut deserts in eastern Iran naturally delimit the region from Balochistan and South Asia.

Plate tectonics
Three major tectonic plates converge on West Asia, including the African, Eurasian, and Arabian plates. The boundaries between the tectonic plates make up the Azores-Gibraltar Ridge, extending across North Africa, the Red Sea, and into Iran. The Arabian Plate is moving northward into the Anatolian plate (Turkey) at the East Anatolian Fault, and the boundary between the Aegean and Anatolian plate in eastern Turkey is also seismically active.

Water resources
Several major aquifers provide water to large portions of West Asia. In Saudi Arabia, two large aquifers of Palaeozoic and Triassic origins are located beneath the Jabal Tuwayq mountains and areas west to the Red Sea. Cretaceous and Eocene-origin aquifers are located beneath large portions of central and eastern Saudi Arabia, including Wasia and Biyadh which contain amounts of both fresh water and saline water. Flood or furrow irrigation, as well as sprinkler methods, are extensively used for irrigation, covering nearly 90,000 km2 across West Asia for agriculture. Also, the Tigris and Euphrates rivers contribute very well.

Climate


West Asia is primarily arid and semi-arid, and can be subject to drought, but it also contains vast expanses of forest and fertile valleys. The region consists of grasslands, rangelands, deserts, and mountains. Water shortages are a problem in many parts of West Asia, with rapidly growing populations increasing demands for water, while salinization and pollution threaten water supplies. Major rivers, including the Tigris and Euphrates, provide sources for irrigation water to support agriculture.

There are two wind phenomena in West Asia: the sharqi and the shamal. The sharqi (or sharki) is a wind that comes from the south and southeast. It is seasonal, lasting from April to early June, and comes again between late September and November. The winds are dry and dusty, with occasional gusts up to 80 kilometres per hour (50 miles per hour) and often kick up violent sand and dust storms that can carry sand a few thousand meters high, and can close down airports for short periods of time. These winds can last for a full day at the beginning and end of the season, and for several days during the middle of the season. The shamal is a summer northwesterly wind blowing over Iraq and the Persian Gulf states (including Saudi Arabia and Kuwait), often strong during the day, but decreasing at night. This weather effect occurs anywhere from once to several times a year.

Topography
West Asia contains large areas of mountainous terrain. The Anatolian Plateau is sandwiched between the Pontus Mountains and Taurus Mountains in Turkey. Mount Ararat in Turkey rises to 5,137 meters. The Zagros Mountains are located in Iran, in areas along its border with Iraq. The Central Plateau of Iran is divided into two drainage basins. The northern basin is Dasht-e Kavir (Great Salt Desert), and Dasht-e-Lut is the southern basin.

In Yemen, elevations exceed 3,700 meters in many areas, and highland areas extend north along the Red Sea coast and north into Lebanon. A fault zone also exists along the Red Sea, with continental rifting creating trough-like topography with areas located well below sea level. The Dead Sea, located on the border between the West Bank, Israel, and Jordan, is situated at 418 meters below sea level, making it the lowest point on the surface of the Earth.

Rub' al Khali, one of the world's largest sand deserts, spans the southern third of the Arabian Peninsula in Saudi Arabia, parts of Oman, the United Arab Emirates and Yemen. Jebel al Akhdar is a small range of mountains located in northeastern Oman, bordering the Gulf of Oman.

Demographics
The population of West Asia was estimated at 272 million as of 2008, projected to reach 370 million by 2030 by Maddison (2007; the estimate excludes the Caucasus and Cyprus). This corresponds to an annual growth rate of 1.4% (or a doubling time of 50 years), well above the world average of 0.9% (doubling time 75 years). The population of West Asia is estimated at 4% of world population, up from about 39 million at the beginning of the 20th century, or about 2% of world population at the time.

The most populous countries in the region are Turkey and Iran, each with around 79 million people, followed by Iraq and Saudi Arabia with around 33 million people each, and Yemen with around 29 million people.

Numerically, West Asia is predominantly Arab, Persian, Turkish, and the dominating languages are correspondingly Arabic, Persian and Turkish, each with of the order of 70 million speakers, followed by smaller communities of Kurdish, Azerbaijani, Hebrew, Armenian and Neo-Aramaic. The dominance of Arabic and Turkish is the result of the medieval Arab and Turkic invasions beginning with the Islamic conquests of the 7th century AD, which displaced the formerly dominant Aramaic in the region of Syria, and Greek in Anatolia, although Hebrew became the dominant language in Israel in the second half of the 20th century, and Neo-Aramaic (spoken by modern Arameans, Assyrians, and Chaldeans) and Greek both remain present in their respective territories as minority languages.

Significant native minorities include, in alphabetical order: Arameans, Assyrians, Chaldeans, Druze, Jews, Lurs, Mandeans, Maronites, Shabaks and Yezidis.

Religion
Four major religious groups (i.e. the two largest religions in the world: Christianity and Islam, plus Judaism and Druze faith) originated in West Asia. Islam is the largest religion in West Asia, but other faiths that originated there, such as Judaism and Christianity, are also well represented.

In Armenia and Georgia, Oriental Orthodoxy and Eastern Orthodoxy respectively are the predominant religions, and there are still different ancient communities of Eastern Christians in Azerbaijan. There are still large ancient communities of Eastern Christians (such as Assyrians, Middle Eastern Christians and Arab Christians) in Lebanon, Iraq, Iran, Turkey, Syria, Jordan, Israel and Palestine numbering more than 3 million in West Asia. There are also large populations of expatriate workers which include sizeable Christian communities living in the Arabian Peninsula numbering more than 3 million. Christian communities have played a vital role in West Asia.

Judaism is the predominant religion in Israel, and there are small ancient Jewish communities in West Asia such as in Turkey (14,300), Azerbaijan (9,100), and Iran (8,756).

The Druze Faith or Druzism originated in West Asia. It is a monotheistic religion based on the teachings of figures like Hamza ibn-'Ali ibn-Ahmad and Al-Hakim bi-Amr Allah and Greek philosophers such as Plato and Aristotle. The number of Druze people worldwide is around one million, with about 45% to 50% living in Syria, 35% to 40% living in Lebanon, and less than 10% living in Israel; recently there has been a growing Druze diaspora.

There are also important minority religions like the Baháʼí Faith, Yarsanism, Yazidism, Zoroastrianism, Mandaeism, and Shabakism.

Economy
The economy of West Asia is diverse and the region experiences high economic growth. Turkey has the largest economy in the region, followed by Saudi Arabia and Iran. Petroleum is the major industry in the regional economy, as more than half of the world's oil reserves and around 40 percent of the world's natural gas reserves are located in the region.
