Maldives is a country of South Asia, situated in the Indian Ocean, south-southwest of India. It consists of approximately 1,196 coral islands grouped in a double chain of 27 atolls, spread over roughly 90,000 square kilometers, making this one of the most disparate countries in the world. Composed of live coral reefs and sand bars, the atolls are situated atop a submarine ridge 960 kilometers long that rises abruptly from the depths of the Indian Ocean and runs from north to south. Only near the southern end of this natural coral barricade do two open passages permit safe ship navigation from one side of the Indian Ocean to the other through the territorial waters of Maldives. For administrative purposes the Maldives government organized these atolls into nineteen administrative divisions.
The largest island of Maldives is Fuvammulah, which is a single island and single atoll located in the southern part of the Maldives known as Gnaviyani Atoll in the administrative division. In Addu Atoll the westernmost islands are connected by roads over the reef and the total length of the road is 12 km.
Geographic coordinates: 3°15′N 73°00′E
Physiography
Most atolls consist of a large, ring-shaped coral reef supporting numerous small islands. Islands average only one to two square kilometers in area, and lie between one and 1.5 meters above mean sea level. The highest island is situated at three meters above sea level. Maldives has no hills or rivers. Although some larger atolls are approximately 50 kilometers long from north to south, and 30 kilometers wide from east to west, no individual island is longer than eight kilometers.
Each atoll has approximately five to ten inhabited islands; the uninhabited islands of each atoll number approximately 20 to 60. Several atolls, however, consist of one large, isolated island surrounded by a steep coral beach. The most notable example of this type of atoll is the large island of Fuvammulah situated in the middle of the Equatorial Channel.
The tropical vegetation of Maldives comprises groves of breadfruit trees and coconut palms towering above dense scrub, shrubs, and flowers. The soil is sandy and highly alkaline, and a deficiency in nitrogen, potash, and iron severely limits agricultural potential. Ten percent of the land, or about 26 km², is cultivated with taro, bananas, coconuts, and other fruit. Only the lush island of Fuvammulah produces fruits such as oranges and pineapples partly because the terrain of Fuvammulah is higher than most other islands, leaving the groundwater less subject to seawater penetration. Freshwater floats in a layer, or "lens," above the seawater that permeates the limestone and coral sands of the islands. These lenses are shrinking rapidly on Male and on many islands where there are resorts catering to foreign tourists. Mango trees already have been reported dying on Male because of salt penetration. Most residents of the atolls depend on groundwater or rainwater for drinking purposes. Concerns over global warming and a possible long-term rise in sea level as a result of the melting of polar ice are important issues to the fragile balance between the people and the environment of Maldives in the 1990s.
