Sri Lanka is a republic and a unitary state which is governed by a semi-presidential system with its official seat of government in Sri Jayawardenapura-Kotte, the capital.
As a result of its location in the path of major sea routes, Sri Lanka is a strategic naval link between West Asia and South East Asia.[12] It has also been a center of the Buddhistreligion and culture from ancient times and is one of the few remaining abodes ofBuddhism in South Asia along with Ladakh, Bhutan and the Chittagong hill tracts.[13] TheSinhalese community forms the majority of the population; Tamils, who are concentrated in the north and east of the island, form the largest ethnic minority. Other communities include Moors, Burghers, Kaffirs, Malays and the aboriginal Vedda people.
The country is famous for the production and export of tea, coffee, coconuts, rubber andcinnamon, the last of which is native to the country.[14] The natural beauty of Sri Lanka has led to the title The Pearl of the Indian Ocean. The island is laden with lush tropical forests, white beaches and diverse landscapes with rich biodiversity. The country lays claim to a long and colorful history of over three thousand years, having one of the longest documented histories in the world. Sri Lanka's rich culture can be attributed to the many different communities on the island. Sri Lanka is a founding member state of SAARC and a member United Nations, Commonwealth of Nations, G77 and Non-Aligned Movement.
The island of Sri Lanka lies in the Indian Ocean, to the southwest of the Bay of Bengal. It lies between latitudes 5° and 10°N, and longitudes 79° and 82°E. Sri Lanka is separated from theIndian subcontinent by the Gulf of Mannar and the Palk Strait. According to Hindu mythology, a land bridge to the Indian mainland, known as Rama's Bridge, was constructed during the time of Rama by the vanara architect Nala. Often referred to as Adam's Bridge, it now amounts to only a chain of limestone shoals remaining above sea level.[22]
According to colonial British reports, this is a natural causeway which was formerly complete, but was breached by a violent storm in 1480.[23] The island consists mostly of flat-to-rolling coastal plains, with mountains rising only in the south-central part. Amongst these is the highest point Pidurutalagala, reaching 2,524 metres (8,281 ft) above sea level.
The climate of Sri Lanka can be described as tropical and warm. Its position between 5 and 10 north latitude endows the country with a warm climate moderated by ocean winds and considerable moisture. The mean temperature ranges from about 16 °C (60.8 °F) in theCentral Highlands, where frost may occur for several days in the winter, to a maximum of approximately 33 °C (91.4 °F) in other low-altitude areas. The average yearly temperature ranges from 28 °C (82.4 °F) to nearly 31 °C (87.8 °F). Day and night temperatures may vary by 4 °C (7.20 °F) to 7 °C (12.60 °F).[citation needed] During the coldest days of January, many people wear coats and sweaters in the highlands and elsewhere.
May, the hottest period, precedes the summer monsoon rains. The rainfall pattern is influenced by monsoon winds from the Indian Ocean and Bay of Bengal: as the winds encounter the mountain slopes of the Central Highlands, they unload heavy rains on the slopes and the southwestern areas of the island. Some of the windward slopes receive up to 2,500 millimetres (98.4 in) of rain each month, but the leeward slopes in the east and northeast receive little rain. Periodic squalls occur and sometimes tropical cyclones bring overcast skies and rains to the southwest, northeast, and eastern parts of the island.
Between December and March, monsoon winds come from the northeast, bringing moisture from the Bay of Bengal. Humidity is typically higher in the southwest and mountainous areas and depends on the seasonal patterns of rainfall, and places like Colomboexperience daytime humidity above 70% all year round, rising to almost 90% during the monsoon season in June. Anuradhapuraexperiences a daytime low of 60% during the monsoon month of March, but a high of 79% during the November and December rains. In the highlands, Kandy's daytime humidity usually ranges between 70% and 79%.
The mountains and the southwestern part of the country, known as the "wet zone", receive ample rainfall at an average of 2,500 mm (98 in). Most of the east, southeast, and northern parts of the country comprise the "dry zone", which receives between 1,200 mm (47 in) and 1,900 mm (75 in) of rain annually. Much of the rain in these areas falls from October to January; during the rest of the year there is very little precipitation. The arid northwest and southeast coasts receive the least amount of rain at 600 mm (24 in) to 1,200 mm (47 in) per year.
Varieties of flowering acacias are well adapted to the arid conditions and flourish on the Jaffna Peninsula. Among the trees of the dry-land forests, are some valuable species such assatinwood, ebony, ironwood, mahogany and teak. In the wet zone, the dominant vegetation of the lowlands is a tropical evergreen forest, with tall trees, broad foliage, and a dense undergrowth of vines and creepers. Subtropical evergreen forests resembling those oftemperate climates flourish in the higher altitudes. Forests at one time covered nearly the entire island, but by the late 20th century lands classified as forests and forest reserves covered around ⅓ of the land.[24]
The Yala National Park in the southeast protects herds of elephant, deer, and peacocks, and the Wilpattu National Park in the northwest preserves the habitats of many water birds, such as storks, pelicans, ibis, and spoonbills. During the Mahaweli Ganga Program of the 1970s and 1980s in northern Sri Lanka, the government set aside four areas of land totalling 1,900 km2 (730 sq mi) as national parks. The island has four biosphere reserves, Bundala,Hurulu Forest Reserve, the Kanneliya-Dediyagala-Nakiyadeniya, and Sinharaja.[25]
The national flower of Sri Lanka is the Nymphaea stellata (Sinhalese Nil Mahanel),[26] the national tree is the Ironwood (Sinhalese Na),[27] and the national bird is the Sri Lanka Junglefowl, which is endemic to the country.[28]
