The Cayman Islands are a British dependency and island country. It is a three-island archipelago in the Caribbean Sea, consisting of Grand Cayman, Cayman Brac, and Little Cayman. Georgetown, the capital of the Cayman Islands is 438 km (272 mi) south of Havana, Cuba ]],[1] and 504 km (313 mi) northwest of Kingston, Jamaica,[2] and are between Cuba and Central America. Georgetown’s geographic coordinates are 19.300° north, 81.383° west. [3]

The Cayman Islands have a land area of 264 km2 (102 sq mi) about 1.5 times the size of Washington, D.C. and just 3 km2 (1.2 sq mi) larger than Saint Kitts and Nevis. The Cayman Islands have a coastline of 160 km (99 mi). The Cayman Islands make a maritime claim of a 200-nautical-mile (370.4 km; 230.2 mi) exclusive fishing zone and a territorial sea of 12 nautical miles (22.2 km; 13.8 mi).[4] [5]

Geology

The islands are located on the Cayman Rise which forms the northern margin of the Cayman Trough. The trough is the deepest point in the Caribbean Sea and forms part of the tectonic boundary between the North American Plate and the Caribbean Plate. The Cayman Rise extends from southeastern Cuba along the northern margin of the Cayman Trough toward Costa Rica and resulted from Paleocene to Eocene island arc formation with associated volcanism along an extinct subduction zone.[6]

Climate

The Cayman Islands have a tropical marine climate, with a wet season of warm, rainy summers (May to October) and a dry season of relatively cool winters (November to April). Terrain is mostly a low-lying limestone base surrounded by coral reefs.

A major natural hazard is the tropical cyclones that form during the Atlantic hurricane season from July to November.

Environmental issues

An important environmental issue is the lack of fresh water resources. Drinking water supplies must be met by rainwater catchment and desalination.

Natural resources

Natural resources include fish and a climate and beaches that foster tourism, which is the islands' major industry. A 2005 estimate of land use determined that the Cayman Islands' had 3.85 percent arable land and no permanent crops.

Districts

The territory is subdivided into seven districts that are governed by district managers and that have a role as electoral districts and as regional units for statistics. Five of the districts are located on the main island Grand Cayman, and the remaining two correspond to the islands of Little Cayman and Cayman Brac:
