The Geographical Area of UAE

The United Arab Emirates is situated in Southwest Asia, bordering the Gulf of Oman and the Persian Gulf, between Oman and Saudi Arabia; it is in a strategic location along southern approaches to the Strait of Hormuz, a vital transit point for world crude oil. The UAE lies between 22°50′ and 26° north latitude and between 51° and 56°25′ east longitude. It shares a 530-kilometer border with Saudi Arabia on the west, south, and southeast, and a 450-kilometer border with Oman on the southeast and northeast. The land border with Qatar in the Khawr al Udayd area is a source of ongoing dispute . The total area of the UAE is approximately 77,700 square kilometers. The country’s exact size is unknown because of disputed claims to several islands in the Persian Gulf, because of the lack of precise information on the size of many of these islands, and because most of its land boundaries, especially with Saudi Arabia, remain undemarcated. The largest emirate, Abu Dhabi, accounts for 87 percent of the UAE’s total area (67,340 square kilometers). The smallest emirate, Ajman, encompasses only 259 square kilometers (see figure).

The UAE stretches for more than 650 kilometers along the southern shore of the Persian Gulf. Most of the coast consists of salt pans that extend far inland. The largest natural harbor is at Dubai, although other ports have been dredged at Abu Dhabi, Sharjah, and elsewhere. Numerous islands are found in the gulf, and the ownership of some of them has been the subject of international disputes with both Iran and Qatar. The smaller islands, as well as many coral reefs and shifting sandbars, are a menace to navigation. Strong tides and occasional windstorms further complicate ship movements near the shore.

The UAE also extends for about 90 kilometers along the Gulf of Oman, an area known as the Al Batinah coast. The Al Hajar al Gharbi (Western Al Hajar) Mountains, rising in places to 2,500 meters, separate the Al Batinah coast from the rest of the UAE. Beginning at the UAE-Oman border on the Persian Gulf coast of the Ras Musandam (Musandam Peninsula), the Al Hajar al Gharbi Mountains extend southeastward for about 150 kilometers to the southernmost UAE-Oman frontier on the Gulf of Oman. The range continues as the Al Hajar ash Sharqi (Eastern Al Hajar) Mountains for more than 500 kilometers into Oman. The steep mountain slopes run directly to the shore in many places. Nevertheless, there are small harbors at Dibba Al-Hisn, Kalba, and Khor Fakkan on the Gulf of Oman. In the vicinity of Al Fujayrah, where the mountains do not approach the coast, there are sandy beaches.

South and west of Abu Dhabi, vast, rolling sand dunes merge into the Rub al Khali (Empty Quarter) of Saudi Arabia. The desert area of Abu Dhabi includes two important oases with adequate underground water for permanent settlements and cultivation. The extensive Al Liwa Oasis is in the south near the undefined border with Saudi Arabia, and about 100 kilometers to the northeast is the Al Buraymi Oasis, which extends on both sides of the Abu Dhabi-Oman border.

Prior to withdrawing from the area in 1971, Britain delineated the internal borders among the seven emirates in order to preempt territorial disputes that might hamper formation of the federation. In general, the rulers of the emirates accepted the British intervention, but in the case of boundary disputes between Abu Dhabi and Dubayy, and also between Dubayy and Sharjah, conflicting claims were not resolved until after the UAE became independent. The most complicated borders were in the Al Hajar al Gharbi Mountains, where five of the emirates contested jurisdiction over more than a dozen enclaves.
