Co-operative Republic of Guyana

Climate
Guyana has a tropical climate, with little seasonal temperature change. The annual rainfall (about 1525 to 2030 mm) on the coast occurs mainly from April to August and November to January. The savanna region receives some 1525 mm of rain annually, mainly from April to September.

Geography
Guyana is situated in the northern part of South-America. The country can be divided into three major geographical regions. A belt of alluvial soil, varying in width from about 8 to 65 km and mostly below sea level, extends along the coast and is protected by a system of dams and dikes. To the south lies the dense forest area that makes up about four-fifths of the country. The forests extend into an interior highland region with a maximum elevation, atop Mount Roraima, of 2772 m. Some of the rivers form spectacular waterfalls, notably Kaieteur Falls (226 m high), on the Potaro River, one of the highest single-drop waterfalls in the world. Beyond the forest lies a region of savanna. Several important rivers - the Essequibo, Demerara, Courantyne (Corantijn), and Berbice - cross the country in a southern to northern direction. The rivers are navigable by oceangoing freighters only to about 100 to 160 km from the sea; farther inland, navigation is not possible because of rapids and falls.

Horticulture
The main fruit and perennial crops are pineapple, citrus, West-Indian cherry, and mango and avocado. Root and tuber crops of interest are cassava, sweet potato, eddo and yam. The main vegetable crops are tomato, ochro, boulanger, and pepper. Plantain and legumes are the major food crops

Distribution of Horticulture
Currently, horticulture is restricted mainly to the coastal belt, due to the relatively high population. Some small scale horticulture is carried out in the interior of the country.
