Geography of Bhutan
From Wikipedia, the free encyclopedia
The Kingdom of Bhutan is a Himalayan nation, located towards the eastern extreme of the aforementioned mountain range. It is fairly evenly sandwiched between the sovereign territory of two nations: first, the People's Republic of China on the north and northwest. There are approximately 470 kilometers of border with that nation's Tibet Autonomous Region. The second nation is the Republic of India on the south, southwest, and east; there are approximately 605 kilometers with the states of Arunachal Pradesh, Assam, West Bengal, and Sikkim, in clockwise order from the kingdom. Bhutan's total borders amount to 1,075 kilometers. The Kingdom of Nepal to the west, the People's Republic of Bangladesh to the south, and the Union of Myanmar to the southeast are other close neighbours; the former two are separated by only very small stretches of Indian territory.
Bhutan is a very compact nation, almost a square but with just a small bit more length than width. The nation's territory totals an approximate 47,000 km². Because of its inland, landlocked status, it controls no territorial waters. Its shape, area, and mountainous location are comparable to that of Switzerland. Bhutan's territory used to extend south into present-day Assam, including the protectorate of Cooch Behar, but, starting in 1772, the British East India Company began to push back the borders through a number of wars and treaties, severely reducing Bhutan's size until the Treaty of Sinchulu of 1865, when some border land was ceded back.

[edit] Political Geography
Bhutan is divided into 20 dzongkhag, and further into 201 gewog.
[edit] Natural Geography
The Himalayas dominate the north of the country, where mountain peaks can easily reach seven thousand meters; the highest point is claimed to be the Kula Kangri, at 7,553 m, but detailed topographic studies claim Kula Kangri is wholly in Tibet and modern Chinese measurements claim that Gangkhar Puensum, which has the distinction of being the highest unclimbed mountain in the world, is higher at 7,570m (vs 7,538m for Kula Kangri). Weather is extreme in the mountains: the high peaks have perpetual snow, and the lesser mountains and hewn gorges have high winds all year round, making them barren brown wind tunnels in summer, and frozen wastelands in winter. The blizzards generated in the north each winter often drift southward into the central highlands.
The highlands are the most populous part of the nation; the capital of Thimphu lies in the western region. The region is characterized by its many rivers (flowing into India's Brahmaputra), its isolated valleys that house most of the population, and the expansive forests that cover seventy percent of the nation. Winters are cold, summer are hot; the rainy season is accompanied with frequented landslides.
The extreme southern strip of the nation consists mostly of tropical plains, more typical of India. It is largely agricultural land, producing mostly rice. Only two percent of Bhutan is arable land, with most of it focused here.
Centuries of isolationism, a small population, and topographical extremes have lead to Bhutan maintaining one of the most intact ecosystems in the world. Over fifty-five hundred varieties of plantlife exist, including around three-hundred medicinal ones. (Cannabis grows wild here, as an example.) 165 species are known to exist, including many rare and endangered species like the red panda, snow leopard, and golden langur.
[edit] Strategic Location
Bhutan, situated between India and Chinese-occupied Tibet, is a potential Sino-Indian battleground; India currently has more political influence in the nation. This stems from two things: the fact that after the British granted sovereignty to their South Asian possessions, Bhutan, a protectorate, was briefly put under the administration of India, along with Sikkim. Independence occurred quickly, but India maintained a special treaty relationship with the now-sovereign monarchy. The Indian Army patrols Bhutan's frontiers and has played a major role in the development of the country's road infrastructure. Additionally, the Government of India continues to provide approximately 60% of Bhutan's government finances.
The second reason comes from the aggression against Tibet by China from 1949 to 1959; the Tibetans have strong cultural, historical, and religious connections to Bhutan.
Bhutan controls several strategic mountain passes through the Himalayas, allowing travel between Tibet and Assam. These passes are also the only way into the kingdom, and, coupled with its centuries-old policies of isolationism, it has been called the "Mountain Fortress of the Gods." The heartland of Bhutan has never been successfully invaded; the British, while establishing a protectorate over the nation, did so with threats to the low-lying territories below the highlands.
[edit] Climate
Bhutan's climate is as varied as its altitudes and, like most of Asia, is affected by monsoons. Western Bhutan is particularly affected by monsoons that bring between 60 and 90 percent of the region's rainfall. The climate is humid and subtropical in the southern plains and foothills, temperate in the inner Himalayan valleys of the southern and central regions, and cold in the north, with year-round snow on the main Himalayan summits.
Temperatures vary according to elevation. Temperatures in Thimphu, located at 2,200 meters above sea level in west-central Bhutan, range from approximately 15° C to 26° C during the monsoon season of June through September but drop to between about -4° C and 16° C in January. Most of the central portion of the country experiences a cool, temperate climate year-round. In the south, a hot, humid climate helps maintain a fairly even temperature range of between 15° C and 30° C year-round, although temperatures sometimes reach 40° C in the valleys during the summer.
Annual precipitation ranges widely in various parts of the country. In the severe climate of the north, there is only about forty millimeters of annual precipitation--primarily snow. In the temperate central regions, a yearly average of around 1,000 millimeters is more common, and 7,800 millimeters per year has been registered at some locations in the humid, subtropical south, ensuring the thick tropical forest, or savanna. Thimphu experiences dry winter months (December through February) and almost no precipitation until March, when rainfall averages 20 millimeters a month and increases steadily thereafter to a high of 220 millimeters in August for a total annual rainfall of nearly 650 millimeters.
Bhutan's generally dry spring starts in early March and lasts until mid-April. Summer weather commences in mid-April with occasional showers and continues through the premonsoon rains of late June. The summer monsoon lasts from late June through late September with heavy rains from the southwest. The monsoon weather, blocked from its northward progress by the Himalayas, brings heavy rains, high humidity, flash floods and landslides, and numerous misty, overcast days. Autumn, from late September or early October to late November, follows the rainy season. It is characterized by bright, sunny days and some early snowfalls at higher elevations. From late November until March, winter sets in, with frost throughout much of the country and snowfall common above elevations of 3,000 meters. The winter northeast monsoon brings gale-force winds down through high mountain passes, giving Bhutan its name-- Drukyul, which in the Dzongkha language mean Land of the Thunder Dragon.
[edit] River systems
Bhutan has four major river systems: the Drangme Chhu; the Puna Tsang Chhu, also called the Sankosh; the Wang Chhu; and the Amo Chhu. Each flows swiftly out of the Himalayas, southerly through the Duars to join the Brahmaputra River in India, and thence through Bangladesh where the Brahmaputra (or Jamuna in Bangladesh) joins the mighty Ganges (or Padma in Bangladesh) to flow into the Bay of Bengal. The largest river system, the Drangme Chhu, flows southwesterly from India's state of Arunachal Pradesh and has three major branches: the Drangme Chhu, Mangde Chhu, and Bumthang Chhu. These branches form the Drangme Chhu basin, which spreads over most of eastern Bhutan and drains the Tongsa and Bumthang valleys. In the Duars, where eight tributaries join it, the Drangme Chhu is called the Manas Chhu. The 320-kilometer-long Puna Tsang Chhu rises in northwestern Bhutan as the Mo Chhu and Pho Chhu, which are fed by the snows from the Great Himalayan Range. They flow southerly to Punakha, where they join to form the Puna Tsang Chhu, which flows southerly into India's state of West Bengal. The tributaries of the 370-kilometer-long Wang Chhu rise in Tibet. The Wang Chhu itself flows southeasterly through west-central Bhutan, drains the Ha, Paro, and Thimphu valleys, and continues into the Duars, where it enters West Bengal as the Raigye Chhu. The smallest river system, the Torsa Chhu, known as the Amo Chhu in its northern reaches, also flows out of Tibet into the Chumbi Valley and swiftly through western Bhutan before broadening near Phuntsholing and then flowing into India.
[edit] Glaciers
Glaciers in northern Bhutan, which cover about 10 percent of the total surface area, are an important renewable source of water for Bhutan's rivers. Fed by fresh snow each winter and slow melting in the summer, the glaciers bring millions of liters of fresh water to Bhutan and downriver areas each year. Glacial melt added to monsoon-swollen rivers, however, also contributes to flooding and potential disaster.
