GUYANA


Geography






Geography
Guyana is a country in Northern South America and part of Caribbean South America, bordering the North Atlantic Ocean, between Suriname and Venezuela. With a land area of approximately 197,000 square kilometres, Guyana is about the size of Idaho. The country is situated between 1 and 9 north latitude and between 56 and 62 west longitude. With a 430-kilometre Atlantic coastline on the northeast, Guyana is bounded by Venezuela on the west, Brazil on the west and south, and Suriname on the east. The land comprises three main geographical zones: the coastal plain, the white sand belt, and the interior highlands

Terrain

The coastal plain, which occupies about 5% of the country's area, is home to more than 90% of its inhabitants. The plain ranges from five to six kilometers wide and extends from the Courantyne River in the east to the Venezuelan border in the northwest.

The coastal plain is made up largely of alluvial mud swept out to sea by the Amazon River, carried north by ocean currents, and deposited on the Guyanese shores. A rich clay of great fertility, this mud overlays the white sands and clays formed from the erosion of the interior bedrock and carried seaward by the rivers of Guyana. Because much of the coastal plain floods at high tide, efforts to dam and drain this area have gone on since the 1700s.

Guyana has no well-defined shoreline or sandy beaches. Approaching the ocean, the land gradually loses elevation until it includes many areas of marsh and swamp. Seaward from the vegetation line is a region of mud flats, shallow brown water, and sandbars. Off New Amsterdam, these mud flats extend almost twenty-five kilometers. The sandbars and shallow water are a major impediment to shipping, and incoming vessels must partially unload their cargoes offshore in order to reach the docks at Georgetown and New Amsterdam.

A line of swamps forms a barrier between the white sandy hills of the interior and the coastal plain. These swamps, formed when water was prevented from flowing onto coastal croplands by a series of dams, serve as reservoirs during periods of drought.

The white sand belt lies south of the coastal zone. This area is 150 to 250 kilometers wide and consists of low sandy hills interspersed with rocky outcroppings. The white sands support a dense hardwood forest. These sands cannot support crops, and if the trees are removed erosion is rapid and severe. Most of Guyana's reserves of bauxite, gold, and diamonds are found in this region.

The largest of Guyana's three geographical regions is the interior highlands, a series of plateaus, flat-topped mountains, and savannahs that extend from the white sand belt to the country's southern borders. The Pakaraima Mountains dominate the western part of the interior highlands. In this region are found some of the oldest sedimentary rocks in the Western Hemisphere. Mount Roraima, on the Venezuelan border, is part of the Pakaraima range and, at 2,762 meters, is Guyana's tallest peak. Farther south lies the Kaieteur Plateau, a broad, rocky area about 600 meters in elevation; the 1,000-meter high Kanuku Mountains; and the low Acarai Mountains situated on the southern border with Brazil.

Much of the interior highlands consist of grassland. The largest expanse of grassland, the Rupununi Savannah, covers about 15,000 square kilometers in southern Guyana. This savannah also extends far into Venezuela and Brazil. The part in Guyana is split into northern and southern regions by the Kanuku Mountains. The sparse grasses of the savannah in general support only grazing, although Amerindian groups cultivate a few areas along the Rupununi River and in the foothills of the Kanuku Mountains.

Hydrology

Guyana is a water-rich country. Numerous rivers flow into the Atlantic Ocean, generally in a northward direction. A number of rivers in the western part of the country, however, flow eastward into the Essequibo River, draining the Kaieteur Plateau. The Essequibo, the country's major river, runs from the Brazilian border in the south to a wide delta west of Georgetown. The rivers of eastern Guyana cut across the coastal zone, making east-west travel difficult, but they also provide limited water access to the interior. Waterfalls generally limit water transport to the lower reaches of each river. Some of the waterfalls are spectacular; for example, Kaieteur Falls on the Potaro River drops 226 metres, more than four times the height of Niagara Falls.


Drainage throughout most of Guyana is poor and river flow sluggish because the average gradient of the main rivers is only one meter every five kilometers. Swamps and areas of periodic flooding are found in all but the mountainous regions, and all new land projects require extensive drainage networks before they are suitable for agricultural use. The average square kilometer on a sugar plantation, for example, has six kilometers of irrigation canals, eighteen kilometers of large drains, and eighteen kilometers of small drains. These canals occupy nearly one-eighth of the surface area of the average sugarcane field. Some of the larger estates have more than 550 kilometers of canals; Guyana itself has a total of more than 8,000 kilometers. Even Georgetown is below sea level and must depend on dikes for protection from the Demerara River and the Atlantic Ocean.

Climate

Lying near the equator, Guyana has a tropical climate, and temperatures do not vary much throughout the year. The year has two wet seasons, from December to early February and from late April to mid-August.

Although the temperature never gets dangerously high, the combination of heat and humidity can at times seem oppressive. The entire area is under the influence of the northeast trade winds, and during the midday and afternoon sea breezes bring relief to the coast. Guyana lies south of the path of Caribbean hurricanes and none is known to have hit the country.

Temperatures in Georgetown are quite constant, with an average high of 32°C and an average low of 24°C in the hottest month (July), and an average range of 29°C to 23°C in February, the coolest month. The highest temperature ever recorded in the capital was 37.2°C and the lowest 16.6°C. Humidity averages 70 percent year-round. Locations in the interior, away from the moderating influence of the ocean, experience slightly wider variations in daily temperature, and nighttime readings as low as 12°C have been recorded. Humidity in the interior is also slightly lower, averaging around 60 percent.

Rainfall is heaviest in the northwest and lightest in the southeast and interior. Annual averages on the coast near the Venezuelan border are near 250 centimetres, farther east at New Amsterdam 200 centimetres, and 150 centimetres in southern Guyana's Rupununi Savannah. Areas on the northeast sides of mountains that catch the trade winds average as much as 350 centimeters of precipitation annually. Although rain falls throughout the year, about 50 percent of the annual total arrives in the summer rainy season that extends from May to the end of July along the coast and from April through September farther inland. Coastal areas have a second rainy season from November through January. Rain generally falls in heavy afternoon showers or thunderstorms. Overcast days are rare; most days include four to eight hours of sunshine from morning through early afternoon.

Education

Education
Guyana's educational system was at one time was considered to be among the best in the Caribbean, but it significantly deteriorated in the 1980s because of the emigration of highly educated citizens and the lack of appropriate funding. Although the education system has recovered somewhat in the 1990s, it still does not produce the quality of educated students necessary for Guyana to modernize its workforce. The country lacks a critical mass of expertise in many of the disciplines and activities on which it depends.

The educational system does not sufficiently focus on the training of Guyanese in science and technology, technical and vocational subjects, business management, nor computer sciences. The Guyanese education system is modeled after the former British education system. Students are expected to write SSEE (secondary school entrance exam) by grade 6 for entrance into High School in grade 7. The write CXC at the end of high school. Recently they have introduced the CAPE exams which all other Caribbean countries have now introduced. The A-level system left over from the British era has all but disappeared and is now offered only in a few schools (current as at January 2007). The reason for the insufficient focus or various disciplines can be directly attributed to the common choices made by students to specialize in areas that are similar (math/chemistry/physics or geography/history/economics). With the removal of the old A-level system that encouraged this specialization, it is thought that it will be more attractive[citation needed] for students to broaden their studies.

There are wide disparities among the geographical regions of the country in the availability of quality education, and the physical facilities which are provided are in poor condition.[citation needed]

Further adding to the problems of the educational system, many of the better-educated professional teachers have emigrated to other countries over the past two decades, mainly because of low pay, lack of opportunities and crime. As a result, there is a lack of trained teachers at every level of Guyana's educational system.

There are however several very good Private schools that have sprung up over the last fifteen years. Those schools offer a varied and balanced curriculum

Dear land of Guyana, of rivers and plains;






Dear land of Guyana, of rivers and plains;
Made rich by the sunshine, and lush by the rains,
Set gem-like and fair, between mountains and sea,
Your children salute you, dear land of the free
Green land of Guyana, our heroes of yore,
Both bondsmen and free, laid their bones on your shore.
This soil so they hallowed, and from them are we,
All sons of one Mother, Guyana the free.
Great land of Guyana, diverse though our strains,
We're born of their sacrifice, heirs of their pains,
And ours is the glory their eyes did not see,
One land of six peoples, united and free.
Dear land of Guyana, to you will we give,
Our homage, our service, each day that we live;
God guard you, great Mother, and make us to be
More worthy our heritage, land of the free.



Languages

Languages
English is the official language of Guyana. In addition, Amerindian languages (see Carib languages) are spoken by a small minority, while Guyanese Creole (an English-based creole with African and Indian syntax) is widely spoken. Grammar is not standardized. [2]

In addition to English, other languages of Guyana include Creole, Akawaio, Wai-Wai, Arawak and Macushi.

Land and People




Land and People

On the east Guyana is separated from Suriname by the Courantyne (Corantijn or Corentyne) River. The Akarai Mts. form the southern border with Brazil. Several rivers make up much of the western border with Brazil and Venezuela, and the Essequibo River flows through the center of the country. There is a cultivated coastal plain and a forested, hilly interior (for a more detailed description of the physical characteristics of the area, see Guiana). The climate is hot and humid, and the rainfall is heavy.

Most of the population lives along the coast. About half of the people trace their ancestry to India, and the rest are of African, mixed, or indigenous descent. English, Hindi, Urdu, and various indigenous dialects are spoken. Christianity and Hinduism are the main religions, and there is a substantial Muslim minority. The Univ. of Guyana in Georgetown was founded in 1963.
