The name Guyana is derived from Guiana, the original name for the region that formerly included Guyana (British Guiana), Suriname (Dutch Guiana), French Guiana, and parts of Colombia, Venezuela and Brazil.ith 215,000 square kilometres (83,000 sq mi), Guyana is the third-smallest country on mainland South America after Uruguay and Suriname. The region known as Guiana or Guyana comprised the large shield landmass north of the Amazon River and east of the Orinoco River known as the Land of many waters.

Much of the country is undeveloped, with more than 90% of the population and almost all of the agriculture concentrated in the narrow coastal plain. The interior is sparsely settled, and communications are poor.
