UAE - Political divisions

The United Arab Emirates is divided into seven emirates, with Abu Dhabi the largest of all seven emirates with an area of 67,340 square kilometers, equivalent to 86.7 per cent of the country’s total area, excluding the islands. It has a coastline extending for more than 400 kilometers and is divided for administrative purposes into three major regions. The Emirate of Dubai extends along the Persian Gulf coast of the UAE for approximately 72 kilometers. Dubai has an area of 3,885 square kilometers, which is equivalent to 5 per cent of the country’s total area, excluding the islands. The Emirate of Sharjah extends along approximately 16 kilometers of the UAE’s Persian Gulf coastline and for more than 80 kilometers into the interior. The northern emirates which include Fujairah, Ajman, Ras al-Khaimah, and Umm al-Qaiwain all have a total area of 3,881 square kilometers. There are two areas under joint control. One is jointly controlled by Oman and Ajman, the other by Fujairah and Sharjah.

There is an Omani exclave surrounded by UAE territory, known as Wadi Madha. It is located halfway between the Musandam peninsula and the rest of Oman in the Emirate of Sharjah. It covers approximately 75 square kilometres (29 sq mi) and the boundary was settled in 1589. The north-east corner of Madha is closest to the Khor Fakkan-Fujairah road, barely 10 metres (33 ft) away. Within the Omani exclave of Madha, is a UAE exclave called Nahwa, also belonging to the Emirate of Sharjah (formerly known as Bhubi Dhubhi). It is about 8 kilometres (5 mi) on a dirt track west of the town of New Madha. It consists of about forty houses with its own clinic and telephone exchange.
