غرب آسیا و خاورمیانه[ویرایش]
غرب آسیا در ایران به عنوان جایگزینی برای خاورمیانه هم به کار میرود. خاورمیانه و غرب آسیا همپوشانی زیادی دارند، اما غرب آسیا شامل کشورهای قفقاز جنوبی مانند جمهوری آذربایجان و ارمنستان و گرجستان نیز میشود.
غرب آسیا شامل ایران، ترکیه، عراق، شبه جزیرهٔ عربستان، قفقاز جنوبی، شام است. اما خاورمیانه قفقاز جنوبی را در بر نمیگیرد. از سوی دیگر بخش اروپایی ترکیه و بخش آفریقایی مصر در غرب آسیا نیست.
Western Asia, West Asia, Southwestern Asia, or Southwest Asia is the westernmost subregion of Asia. It includes Anatolia, the Arabian Peninsula, Iran, the Levant, Mesopotamia, the Sinai Peninsula, and Transcaucasia. The region is considered to be separated from Africa by the Isthmus of Suez, and separated from Europe by the waterways of the Turkish Straits and the drainage divide of the Caucasus Mountains. Central Asia lies to the northeast of Western Asia while South Asia lies to the east.
20 countries are located fully or partly in Western Asia, out of which 13 are part of the Arab world. The most populous countries in Western Asia are Turkey (partly in Southeast Europe), Iran, Iraq, Saudi Arabia, and Yemen. The total population of Western Asia is estimated to be 300 million (as of 2015).
The term is used pragmatically and has no "correct" or generally agreed-upon definition. 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) only includes Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Palestinian territories (called West Bank and Gaza in the latter), Saudi Arabia, Syria, Turkey, UAE, and Yemen as West Asian countries. The Caucasus nations of Armenia, Azerbaijan and Georgia are included in definitions or histories of Eastern Europe.Two of them Azerbaijan and Georgia are transcontinental countries geographically located at the crossroads of Western Asia and Eastern Europe. They participate in the European Union's Eastern Partnership program, the Euronest Parliamentary Assembly, and are members of the Council of Europe, which specifies that all three have political and cultural connections to Europe. In January 2002, the European Parliament noted that Armenia and Georgia may enter the EU in the future. However, Georgia is currently the only Caucasus nation actively seeking NATO and EU membership. In contrast to this definition, the United Nations Industrial Development Organization (UNIDO) in its 2015 yearbook also 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 Western 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 Western 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 thirteen 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.
"Western Asia" was in use as a geographical term in the early 19th century, even 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.
Western Asia is located directly south of Eastern Europe. The region is surrounded by seven major seas; the Aegean Sea, the Black Sea, the Caspian Sea, the Persian Gulf, the Arabian Sea, the Red Sea, and the Mediterranean Sea.
To the north, the region is delimited from Europe by the 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.
Three major tectonic plates converge on Western 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.
Several major aquifers provide water to large portions of Western 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 Western Asia for agriculture. Also, the Tigris and Euphrates rivers contribute very well.
Western 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 Western 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.
Western 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 m (1371 ft) 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.
The population of Western 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 Western Asia is estimated at about 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, Western 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 Eastern 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 and Hebrew in the Levant, and Greek in Anatolia, although Hebrew is once again the dominant language in Israel, and Aramaic (spoken largely by Chaldeans, Arameans and Assyrians) and Greek both remain present in their respective territories as minority languages.
The economy of Western 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.
