10 Facts About The Largest Peninsula In The World

The Arabian peninsula or Arabia is the largest peninsula in the world. Also known as the Island of Arabs or Jazirat-Al-Arab, it is located in the southwestern part of Asia. It is bounded by important gulfs and seas which serve as vital shipping lanes, connecting the Middle East with the other world economies.

The Arabian peninsula has a total area of about 1,250,000 square miles. It is surrounded by the Red Sea and the Gulf of Aden from the southwest. The southeastern coast faces the Arabian Sea while the eastern coastline is enclosed by the Oman Gulf and the Persian Gulf.

The Peninsula is not clearly demarcated, however it includes the wealthiest nations of Oman, UAE, Saudi Arabia, Yemen, Qatar, Kuwait, southern parts of Iraq and Jordan.

1. Desert covers the largest portion of the Arabian Peninsula

An enormous chunk of Arabia is covered with shifting sand dunes. In fact, the second-largest desert in the world after Sahara is found in the Arabian Peninsula. It is home to numerous Bedouin tribes practising the old way of life. Spanning more than 899, 618 square miles, it is three times larger than Spain.

The Empty Quarter or the Rub’ al Khali is a part of the expansive Arabian desert. It covers a thousand kilometres and is known for the highest sand dunes rising to 250 metres. The terrain has gravel and gypsum mixed with reddish-orangish sand. The Umm al Salim region on the eastern end is known for brackish salt flats.

Interestingly, the sand dunes of Empty Quarter retain their shape even though strong winds blow away sand particles. This is due to nearby sabkhas or mudflats that supply moisture to the base of these dunes. The picturesque desert has been a part of many movies such as the 2015 Star Wars. It is also a tourist destination where people enjoy desert safaris and camp nights under the stars.

The largest tribe inhabiting the Rub’ al Khali is the Al Murrah. They live in tents between the regions of Al-Ahsa and Najran. Other tribes of the region include Banu Hamdan and Bani Yas. Roads connect these settlements to nearby towns and water resources.

2. Formed 60 million years ago

The geological history of the Arabian peninsula can be traced back to a hundred million years. The process geared up with the Red sea rift which occurred 56 to 24 million years ago, creating the landmass known as Arabia. The peninsula lies on the Arabian tectonic plate, hence it is also called the Arabian subcontinent by geographers.
The Arabian plate is drifting apart from Africa and moving towards Asia. It is pressing into the Eurasian landmass, especially the Zagros mountains. In a hundred years or so, the region may become seismically active.

The Peninsula is home to several extinct volcanoes whose eruptions ceased eight thousand years ago. However, solidified lava formed Harrahs or black mounds, a unique feature of Western Arabia. Exposed sedimentary and igneous rocks cover the peninsula. The oldest ones are found in the Nubian shield, close to the Red Sea coast while the youngest formations line the Persian gulf. The Semail Ophiolite covers the Arabian mountain ranges and Oman.

The sedimentary deposits consist of limestone, shale and sandstone. They are found in the Arabian shield and date back to the Paleozoic period, around 400 to 550 million years ago. Traces of ancient seas and trapped water are found in the eastern parts of the Peninsula. Before carving political boundaries, the region was divided into four areas; the central plateau or the Najd, Southern Arabia, East Arabia or Al-Bahrain and the Hejaz.

3. Experience hot and arid climate

The Arabian Peninsula faces scorching heat, with the highest temperatures reaching up to 55 degrees Celsius in summer. The Tropic of Cancer divides the region as it passes through Medina in Saudi Arabia. Inner regions are prone to hot and dry weather while coastal areas and southern mountainous zones struggle with high levels of humidity. Fog and morning dew is common in these areas. The Autumn and spring seasons witness cool breezes and pleasant weather in most places.

Winters are mild except in the elevated regions of the north and the mountain zones that witness occasional snowfall. Water laden winds from the Indian Ocean lose their moisture before arriving at the peninsula, causing scanty rainfall. Desert areas face torrential rains rarely, accompanied by hail, leading to flash floods. Droughts are common in the peninsula, making water a prized commodity.

Monsoon months are short and generous to the southwestern part of the Arabian peninsula, which sees more precipitation compared to other areas. Winds arriving from the Mediterranean sea towards the Persian Gulf bring rain to Northern regions and Yemen.

4. Possessor of the world’s largest oil reserves

Arab nations have strong economies attributed to the presence of abundant black gold in the region. Large oil fields are found in Yemen, Saudi Arabia, Iran and Iraq. The Middle East meets the world’s energy requirements and controls the oil prices, having a significant hold on the global economy. This also accords geopolitical importance to the Peninsula.

Oil was discovered in the region in the 1900s and Saudi Arabia possesses the largest oil reserves in the Peninsula, amounting to 298 thousand million barrels. The Al-Ghawar, situated in the Al-Ahsa province of Saudi Arabia is the biggest oil field on earth. Operated by Saudi Aramco, it covers 280 kilometres and comprises a third of the nation’s total oil production. Burgan oil fields in Kuwait and Qurna II and Rumaila of Iraq are other prominent oil fields producing thousands of barrels.

Huge reserves of natural gas are also found in the region. However, exploiting them requires huge investments. Much of the liquified natural gas is exported to Europe and South Asia.

5. Rich in minerals and precious metals like gold, silver and copper

Apart from oil and natural gas, the Arab countries also have metals and minerals. However, these resources are not exploited as the economy is highly dependent on oil. Many countries have financed exploration programs for diversifying their economic base.

In ancient and mediaeval times, gold and silver were mined from Mahd al-Dhahab and Marib in Hejaz. Copper deposits are found in the mountains of Oman. Iron ore is abundant in northern Najd and western parts of Saudi Arabia. Large amounts of gypsum, salts, phosphorite, clay, shale, magnesite, quartz, silica and stone are also found. These materials are used for making traditional Arabian pottery, handicrafts, utensils and bricks.

Oyster cultivation was once a lucrative profession in the Arabian peninsula. Top-quality pearls were derived from the Persian gulf’s oyster shells. The major centres of pearling were Bahrain, Qatar and the UAE. However, the 1930s economic slump and the stiff competition from Japanese pearls led to declining profits and the eventual closure of this business.

6. Home to unique flora and fauna

Date palms and coconut palms are the most common trees on the Peninsula. High-quality dates are exported from the Muslim holy cities of Mecca and Medina. The scarcity of water and infertile soil make widespread agriculture impossible. However, some places are suitable for growing grains like millets, wheat and sorghum.

Arabians cherish fruits over vegetables and juicy ones like pomegranates and melons are cultivated near oases. Interestingly, mango cultivation started in Al-Buraimi while figs, pears, grapes and almonds are also grown.

Coffee is cultivated on a small scale in Yemen while tobacco is grown near Hadhramaut shore. Medicinal herbs and natural dyes like indigo are found in southern regions. Resin is extracted locally from Mimosa plants and some types of cactus. Flowering plants are a rare sight however the roses of Taif are a sight to behold.

The rugged terrain is traversed on a camel; bedouins also own numerous sheep, goats and horses. Salukis and falcons are kept for hunting deer, rabbits and other small animals. Wolves, foxes, hyenas, baboons, cobra, lizards and scorpions live in the desert. The coastal areas house pelicans, pigeons, flamingoes, cuckoos etc.

7. Cradle of many ancient Civilisations

The Arabian peninsula was inhabited by Homo Sapiens who migrated from Africa to Arabia 95,000 years ago. This fact is corroborated by archaeological findings in the Al Wusta desert area which revealed fossilised remains of archaic human species.

Acheulian tools from the Palaeolithic period were found in parts of Saudi Arabia, indicating thriving human settlements. This is obvious since Arabia was a lush green land about 300,000 years ago. Prehistoric sites were discovered in Al-Qassam and Shuaib-Al-Adgham.

Romans controlled the region in the first century AD, after which numerous kingdoms like the Sheba, Awsan and others emerged in Southern Arabia. The largest civilisation was the Dilmun which flourished in eastern Arabia.

The Arabs were traditionally divided into different tribes which controlled strategic resources. Islam spread in the 7th century and powerful Islamic kingdoms like Fatimids, Ummayads and Abbasids gained ground in the region. In mediaeval times, much of the Peninsula was controlled by the Ottoman Empire. The modern era has witnessed growing dissensions, civil wars, coups and conflicts, especially in Iraq, Iran and Yemen.

8. Arabian peninsula offers a perfect holiday getaway

The Middle East is becoming a popular tourist destination for travellers. Endowed with fun-filled activities, sky-scrapers, sandy beaches and vibrant culture, the Arabian peninsula is sure to make a memorable holiday trip for all age groups.

Oases and marshes exist in eastern parts while the red sea coast is lined with coral reefs. The only source of water is seasonal streams which form wadis. Al-Ahsa and Qatif are the two biggest oases in the world.

Al-Ahsa is situated in eastern Arabia near the Abqaiq province. It contains lush gardens, ancient canals and waterworks, wells and inland lakes. Humans have lived in the oases from the Neolithic period onwards as evident from historical findings. It has 2.5 million date palms, forts, mosques and archaeological sites.

One of the oldest settlements in Saudi Arabia, Qatif has fertile soil that supports agriculture. The region has many natural springs and fortifications built to repel Portuguese attacks in the 15th century. The eastern coastline of the coastal city borders the Red sea. Hence, Qatif was once an important trading post for Arabs.

10. Home to the ninth-busiest port in the World
