Guyana, officially the Co‑operative Republic of Guyana, isa country on the northern mainland of South America and the capital city is Georgetown. It is part of the mainland Caribbean region maintaining its strong cultural, historical, and political ties with other Caribbean countries and the Caribbean Community (CARICOM). Guyana isbordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east. With 215,000 square kilometres (83,000 sq mi), Guyana is the third-smallest sovereign state by area in mainland South America after Uruguay and Suriname; it is also the second-least populous sovereign state in South America after Suriname.

The region known as "the Guianas" consists of the large shield landmass north of the Amazon River and east of the Orinoco River known as the "land of many waters". There are nine indigenous tribes residing in Guyana: the WaiWai, Macushi, Patamona, Lokono, Kalina, Wapishana, Pemon, Akawaio and Warao. Historically dominated by the Lokono and Kalina tribes, Guyana was colonised by the Dutch before coming under British control in the late 18th century. It was governed as British Guiana, with a mostly plantation-style economy until the 1950s. It gained independence in 1966, and officially became a republic within the Commonwealth of Nations in 1970. The legacy of British rule is reflected in the country's political administration and diverse population, which includes Indian, African, Amerindian, Chinese, Portuguese, other European, and various multiracial groups. In 2017, 41% of the population of Guyana lived below the poverty line.^[11]

Guyana is the only South American nation in which English is the official language. The majority of the population, however, speak Guyanese Creole, an English-based creole language, as a first language. Guyana is part of the Anglophone Caribbean. CARICOM headquarters is in Guyana's capital and largest city, Georgetown. In 2008, the country joined the Union of South American Nations as a founding member.

The name "Guyana" derives 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. According to the Oxford English Dictionary, "Guyana" comes from an indigenous Amerindian language and means "land of many waters".

There are nine indigenous tribes residing in Guyana: the WaiWai, Macushi, Patamona, Lokono, Kalina, Wapishana, Pemon, Akawaio and Warao. Historically, the Lokono and Kalina tribes dominated Guyana. Although Christopher Columbus was the first European to sight Guyana during his third voyage (in 1498), and Sir Walter Raleigh wrote an account in 1596, the Dutch were the first Europeans to establish colonies: Pomeroon (1581), Essequibo (1616), Berbice (1627),and Demerara (1752). After the British assumed control in 1796, the Dutch formally ceded the area in 1814. In 1831 the three separate colonies became a single British colony known as British Guiana.

Since its independence in 1824, Venezuela has claimed the area of land to the west of the Essequibo River. Simón Bolívar wrote to the British government warning against the Berbice and Demerara settlers settling on land which the Venezuelans, as assumed heirs of Spanish claims on the area dating to the sixteenth century, claimed was theirs. In 1899 an international tribunal ruled the land belonged to Great Britain.^[16] The British territorial claim stemmed from Dutch involvement and colonization of the area also dating to the sixteenth century, which was ceded to the British.

Guyana achieved independence from the United Kingdom as a dominion on 26 May 1966 and became a republic on 23February 1970, remaining a member of the Commonwealth. Shortly after independence, Venezuela began to take diplomatic, economic and military action against Guyana in order to enforce its territorial claim to the Guayana Esequiba.^[17] The US State Department and the US Central Intelligence Agency (CIA), along with the British government, also played a strong role in influencing political control in Guyana during this time.^[18] The American government supported Forbes Burnham during the early years of independence because Cheddi Jagan was identified as a Marxist. They provided secret financial support and political campaign advice to Burnham's People's National Congress, to the detriment of the Jagan-led People's Progressive Party, which was mostly supported by Guyanese of East Indian background.

In 1974, the Guyana government leased 1,500hectares (3,800 acres) of land to Peoples Temple, an American new religious movement, led by pastor Jim Jones. The settlement, informally called "Jonestown", eventually grew to a population of about 1,000 people, mostly emigrated from the United States. In 1978, Guyana received worldwide attention when 909 people died in a mass murder/suicide in Jonestown by drinking cyanide-laced Flavor Aid. A day prior, U.S. congressman Leo Ryan had visited and toured the settlement as part of an investigation. As he was preparing to leave at the Port Kaituma airstrip, a group of Peoples Temple members pulled up and opened fire on the visiting delegation, killing Ryan and four other people.

In May 2008, President Bharrat Jagdeo was a signatory to the UNASURConstitutive Treaty of the Union of South American Nations. The Guyanese government officially ratified the treaty in 2010.

The territory controlled by Guyana lies between latitudes 1° and 9°N, and longitudes 56° and 62°W, and is one of the world's most sparsely populated countries.

The country can be divided into five natural regions; a narrow and fertile marshy plain along the Atlantic coast(low coastal plain) where most of the population lives; a white sand belt more inland (hilly sand and clay region), containing most of Guyana's mineral deposits; the dense rain forests (Forested Highland Region) in the southern part of the country; the drier savannah areas in the south-west; and the smallest interior lowlands (interior savannah)consisting mostly of mountains that gradually rise to the Brazilian border.

Some of Guyana's highest mountains are Mount Ayanganna (2,042 metres or 6,699 feet), Monte Caburaí (1,465metres or 4,806 feet) and Mount Roraima (2,772metres or 9,094 feet – the highest mountain in Guyana) on the Brazil-Guyana-Venezuela tripoint border, part of the Pakaraima range. Mount Roraima and Guyana's table-top mountains (tepuis) are said to have been the inspiration for Sir Arthur Conan Doyle's 1912 novel The Lost World. There are also many volcanic escarpments and waterfalls, including Kaieteur Falls which is believed to be the largest single-drop waterfall in the world.^[19] North of the Rupununi River lies the Rupununi savannah, south of which lie the Kanuku Mountains.

The four longest rivers are the Essequibo at 1,010 kilometres (628 mi) long, the Courentyne River at 724 kilometres(450 mi), the Berbice at 595kilometres (370 mi), and the Demerara at 346 kilometres (215 mi).The Courentyne river forms the border with Suriname. At the mouth of the Essequibo are several large islands, including the 145 km (90 mi)wide Shell Beach along the northwest coast, which is also a major breeding area for sea turtles (mainly leatherbacks) and other wildlife.

The local climate is tropical and generally hot and humid, though moderated by northeast trade winds along the coast. There are two rainy seasons, the first from May to mid-August, the second from mid-November to mid-January.

Guyana has one of the largest unspoiled rainforests in South America, some parts of which are almost inaccessible by humans. The rich natural history of Guyana was described by early explorers Sir Walter Raleigh and Charles Waterton and later by naturalists Sir David Attenborough and Gerald Durrell. In2008, the BBC broadcast a three-part programme called Lost Land of the Jaguar which highlighted the huge diversity of wildlife, including undiscovered species and rare species such as the giant otter and harpy eagle.

In 2012, Guyana received a $45 million reward from Norway for its rainforest protection efforts. This stems from a2009 agreement between the nations for a total of $250 million for protecting and maintaining the natural habitat. Thus far, the country has received $115million of the total grant.

Regions and Neighbourhood Councils

Guyana is divided into 10 regions The regions are divided into 27 neighbourhood councils.

Boundary disputes

Guyana is in border disputes with both Suriname, which claims the area east of the left bank of the Corentyne River and the New River in southwestern Suriname, and Venezuela which claims the land west of the Essequibo River, once the Dutch colony ofEssequibo as part of Venezuela's Guayana Essequiba.^{[23][24][25][26]} The maritime^[27][28] component of the territorial dispute with Suriname was arbitrated by the United Nations Convention on Law of the Sea, and a ruling was announced on 21 September 2007. The ruling concerning the Caribbean Sea north of both nations found both parties violated treaty obligations and declined to order any compensation to either party.^[29]

When the British surveyed British Guiana in1840, they included the entire Cuyuni River basin within the colony. Venezuela did not agree with this as it claimed all lands west of the Essequibo River. In 1898, at Venezuela's request, an international arbitration tribunal was convened, and in 1899 the tribunal issued an award giving about 94% of the disputed territory to British Guiana. The arbitration was concluded, settled and accepted into International law by both Venezuela and the U.K. Venezuela brought up again the settled claim, during the1960s cold war period, and during Guyana's Independence period. This issue is now governed by the Treaty of Geneva of 1966, which was signed by the Governments of Guyana, Great Britain and Venezuela, and Venezuela continues to claim GuayanaEsequiba.^[30] Venezuela calls this region "Zona en Reclamación" (Reclamation Zone) and Venezuelan maps of the national territory routinely include it, drawing it in with dashed lines.^[31]

Specific small disputed areas involving Guyana are Ankoko Island with Venezuela; Corentyne River^[32] with Suriname; and Tigri Area or New River Triangle^[33] with Suriname. In 1967 a Surinamese survey team was found in the New River Triangle and was forcibly removed. In August 1969 a patrol of the Guyana Defence Force found a survey camp and a partially completed airstrip inside the triangle, and documented evidence of the Surinamese intention to occupy the entire disputed area. After an exchange of gunfire,the Surinamese were driven from the triangle.

Environment and biodiversity

The following habitats have beencategorised for Guyana: coastal, marine, littoral, estuarine palustrine,mangrove, riverine, lacustrine, swamp, savanna, white sand forest, brown sandforest, montane, cloud forest, moist lowland and dry evergreen scrub forests(NBAP, 1999). About 14 areas of biological interest have been identified aspossible hotspots for a National Protected Area System. More than 80% of Guyanais still covered by forests, those forest also contains the world'srarest orchids ranging from dry evergreen and seasonal forests tomontane and lowland evergreen rain forests. These forests are home to more thana thousand species of trees. Guyana's tropical climate, unique geology, andrelatively pristine ecosystems support extensive areas of species-rich rainforests and natural habitats with high levels of endemism.Approximately eight thousand species of plants occur in Guyana, half of whichare found nowhere else.

Guyana has one of the highest levelsof biodiversity in the world. With 1,168 vertebrate speciesand 814 bird species, it boasts one of the richest mammalian fauna assemblagesof any comparably sized area in the world. Guyana is home to sixecoregions: GuayananHighlands moist forests, Guianan moist forests, OrinocoDelta swamp forests, Tepuis, Guianan savanna, and Guianan mangroves.^[34] TheGuiana Shield region is little known and extremely rich biologically. Unlikeother areas of South America, over 70% of the natural habitat remains pristine. Guyana ranks third in the world with a 2019 ForestLandscape Integrity Index mean score of 9.58/10.^[35]

The rich natural history of British Guiana was described by early explorers Sir Walter Raleigh and Charles Waterton and later by naturalists Sir David Attenborough and Gerald Durrell.

In February 2004, the Government of Guyanaissued a title to more than 4,000 square kilometres (1×10⁶ acres)of land in the Konashen Indigenous District declaring this land as the KonashenCommunity-Owned Conservation Area (COCA), to be managed by the Wai Wai. In doing so Guyana created the world's largest Community-Owned Conservation Area.^[36]

This important event followed a request made by the Wai Wai community to the government of Guyana and ConservationInternational Guyana (CIG) for assistance in developing a sustainable plan fortheir lands in Konashen. The three parties signed a Memorandum of Cooperationwhich outlines a plan for sustainable use of the Konashen COCA's biologicalresources, identifies threats to the area's biodiversity, and helps developprojects to increase awareness of the COCA as well as generate the incomenecessary to maintain its protected status.

The Konashen Indigenous District ofSouthern Guyana houses the headwaters of the Essequibo River, Guyana'sprincipal water source, and drains the Kassikaityu, Kamoa, Sipu and Chodikarrivers. Southern Guyana is host to some of the most pristine expanses ofevergreen forests in the northern part of South America. Most of the forestsfound here are tall, evergreen hill-land and lower montane forests, with largeexpanses of flooded forest along major rivers. Thanks to the very low humanpopulation density of the area, most of these forests are still intact. TheSmithsonian Institution has identified nearly 2,700 species of plants from thisregion, representing 239 distinct families, and there are certainly additionalspecies still to be recorded.

The diversity of plants supports diverseanimal life, recently documented by a biological survey organised byConservation International. The reportedly clean, unpolluted waters of theEssequibo watershed support a remarkable diversity of fish and aquaticinvertebrates, and are home to giant otters, capybaras, andseveral species of caimans.

On land, large mammals, such as jaguars, tapirs, bush dogs, giant anteaters,and saki monkeys are still common. Over 400species of birds have been reported from the region, and the reptile and amphibian faunas are similarly rich. The Konashen COCA forests are also home tocountless species of insects, arachnids, and other invertebrates, many of which are still undiscovered or unnamed.

The Konashen COCA contains a high level of biological diversity and richness that remains in nearly pristine condition;such places have become rare on earth. This fact has given rise to various non-exploitative, environmentally sustainable industries such as ecotourism,successfully capitalising on the biological wealth of the Konashen COCA with comparatively little enduring impact.
