borneo island (pulau kalimantan)

Borneo (/ˈbɔrnioʊ/; Indonesian: Kalimantan, Malay: Borneo) is the third-largest island in the world and the largest island in Asia.^[1] At the geographic center of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west ofSulawesi, and east of Sumatra.

The island is divided among three countries: Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. Additionally, the Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo's land area. Borneo is home to one of the oldest rainforests in the world.

Etymology[edit]

The island is known by many names; internationally it is known as Borneo, after Brunei, derived from European historical contact with the kingdom in the 16th century during the Age of Exploration. The name Brunei possibly was initially derived from the Sanskrit word "varuṇ" (वरुण), meaning either "ocean" or the mythological Varuna, the "god of the ocean." Indonesian natives called it Kalimantan,which was derived from the Sanskrit word Kalamanthana, meaning "burning weather island" (to describe its hot and humid tropicalweather).^[2]

Prior to that the island was also known by other names. In 977 Chinese records began to use the term Po-ni to refer to Borneo. In 1225 it was also mentioned by the Chinese official Chua Ju-Kua(趙汝适).^[3] The Javanese manuscript Nagarakretagama, written byMajapahit court poet Mpu Prapanca in 1365, mentioned the island as Nusa Tanjungnagara, which means the island of theTanjungpura Kingdom.^[4]

Geography[edit]

Mount Kinabalu

Borneo is surrounded by the South China Sea to the north and northwest, the Sulu Sea to the northeast, the Celebes Sea and the Makassar Strait to the east, and the Java Sea andKarimata Strait to the south. To the west of Borneo are the Malay Peninsula and Sumatra. To the south and east are islands of Indonesia: Java and Sulawesi, respectively. To the northeast are the Philippine islands.

With an area of 743,330 square kilometres (287,000 sq mi), it is the third-largest island in the world, and is the largest island of Asia (the largest continent). Its highest point is Mount Kinabalu in Sabah, Malaysia, with an elevation of 4,095 m (13,435 ft).^[5]

The largest river system is the Kapuas in West Kalimantan, with a length of 1,143 km (710 mi). Other major rivers include the Mahakam inEast Kalimantan (980 km long (610 mi)), the Barito in South Kalimantan (880 km long (550 mi)), and Rajang in Sarawak (562.5 km long (349.5 mi)).^{[citation needed]}

Borneo has significant cave systems. Clearwater Cave, for example, has one of the world's longest underground rivers. Deer Cave is home to over three million bats, with guanoaccumulated to over 100 metres (330 ft) deep.^[6]

Before sea levels rose at the end of the last Ice Age, Borneo was part of the mainland of Asia, forming, with Java and Sumatra, the upland regions of a peninsula that extended east from present day Indochina. The South China Sea and Gulf of Thailand now submerge the former low-lying areas of the peninsula. Deeper waters separating Borneo from neighbouring Sulawesi prevented a land connection to that island, creating the divide between Asian and Australia-New Guinea biological regions, known as Wallace's Line.^{[citation needed]}

Ecology[edit]

The Borneo rainforest is 140 million years old, making it one of the oldest rainforests in the world. There are about 15,000 species offlowering plants with 3,000 species of trees (267 species are dipterocarps), 221 species of terrestrial mammals and 420 species of resident birds in Borneo.^[7] There are about 440 freshwater fish species in Borneo (about the same as Sumatra and Java combined).^[8] It is the centre of the evolution and distribution of many endemic species of plants and animals. The Borneo rainforest is one of the few remaining natural habitats for the endangered Bornean orangutan. It is an important refuge for many endemic forest species, including the Asian elephant, the Sumatran rhinoceros, the Bornean clouded leopard, the Hose's civet and the dayak fruit bat.^{[citation needed]}

In 2010 the World Wide Fund for Nature stated that 123 species have been discovered in Borneo since the "Heart of Borneo" agreement was signed in 2007.^[9]

The WWFN has classified the island into seven distinct ecoregions. Most are lowland regions:^{[citation needed]}

• Borneo lowland rain forests cover most of the island, with an area of 427,500 square kilometres (165,100 sq mi);
• Borneo peat swamp forests;
• Kerangas or Sundaland heath forests;
• Southwest Borneo freshwater swamp forests; and
• Sunda Shelf mangroves.
• The Borneo montane rain forests lie in the central highlands of the island, above the 1,000 metres (3,300 ft) elevation. The highest elevations of Mount Kinabalu are home to the Kinabalu mountain alpine meadow, an alpine shrubland notable for its numerous endemic species, including many orchids.

The island historically had extensive rainforest cover, but the area was reduced due to heavy logging for the Malaysian and Indonesian plywood industry. Half of the annual global tropical timber acquisition comes from Borneo. Palm oil plantations have been widely developed and are rapidly encroaching on the last remnants of primary rainforest. Forest fires of 1997 to 1998, started by the locals to clear the forests for plantations were exacerbated by an exceptionally dry El Niño season, worsening the annual shrinkage of the rainforest. During these fires, hotspots were visible on satellite images and the resulting haze affected four countries: Brunei, Malaysia, Indonesia, and Singapore.^{[citation needed]}

In 2010 Sarawak announced a plan for energy production, the Sarawak Corridor of Renewable Energy, to try to establish sustainability.^[10]

History[edit]

Early history[edit]

Dayaks, the natives of Borneo in their traditional war dress. Headhuntingwas an important part of Dayak culture.

According to ancient Chinese (977),^[11]:129 Indian and Javanese manuscripts, western coastal cities of Borneo had become trading ports by the first millennium.^[12] In Chinese manuscripts, gold, camphor, tortoise shells, hornbill ivory, rhinoceros horn, crane crest, beeswax, lakawood (a scented heartwood and root wood of a thick liana, Dalbergia parviflora), dragon's blood, rattan, edible bird's nests and various spices were described as among the most valuable items from Borneo.^[13] The Indians named Borneo Suvarnabhumi (the land of gold) and also Karpuradvipa (Camphor Island). The Javanese named Borneo Puradvipa, or Diamond Island. Archaeological findings in the Sarawak river delta reveal that the area was a thriving trading centre between India and China from the 500s until about 1300 AD.^[13]

One of the earliest evidence of Hindu influence in Southeast Asia were stone pillars which bear inscriptions in the Pallava script, found inKutai along the Mahakam River in East Kalimantan, dating to around the second half of the 300s AD.^[14]

King Sri Maharaja of P'o-ni sent an embassy to China in 1082, according to the History of Song.^[15]:158

By the 14th century, Borneo was under the control of the Majapahit kingdom based in present-day Indonesia.^[16] Muslims entered the island and converted many of the indigenous peoples to Islam.^{[citation needed]}

During the 1450s, Shari'ful Hashem Syed Abu Bakr, an Arab born in Johor, arrived in Sulu from Malacca. In 1457, he founded the Sultanate of Sulu; he titled himself as "Paduka Maulana Mahasari Sharif Sultan Hashem Abu Bakr". The Sultanate of Brunei, during its golden age from the 15th century to the 17th century, ruled a large part of northern Borneo. In 1703 (other sources^[who?] say 1658), the Sultanate of Sulu received the eastern part of North Borneo from the Sultan of Brunei, after Sulu sent aid against a rebellionin Brunei.^{[citation needed]}

Dutch and British control[edit]

The Sultanate of Brunei granted large parts of land in Sarawak in 1842 to the English adventurer James Brooke, as reward for his having helped quell a local rebellion. Brooke established the Kingdom of Sarawak and was recognised as its rajah after paying a fee to the Sultanate. He established a monarchy, and the Brooke dynasty (through his nephew and great-nephew) ruled Sarawak for 100 years; the leaders were known as the White Rajahs.^[17]

In the early 19th century, British and Dutch governments signed the Anglo-Dutch Treaty of 1824 to exchange trading ports under their controls and assert spheres of influence. This resulted in indirectly establishing British- and Dutch-controlled areas in Borneo, in the north and south, respectively. The Malay and Sea Dayak pirates preyed on maritime shipping in the waters between Singapore and Hong Kong from their haven in Borneo.^[18]

The British North Borneo Company controlled the territory of North Borneo (present-day Sabah) from 1882 to 1941.^[19]

World War II[edit]

See also: Japanese occupation of British Borneo, Japanese occupation of the Dutch East Indies and Pontianak incidents

During World War II, Japanese forces gained control and occupied Borneo (1941–45). They decimated many local populations and killed Malay intellectuals, executing all the Malay Sultans of Kalimantan in the Pontianak incidents. Sultan Muhammad Ibrahim Shafi ud-din II ofSambas in Kalimantan was executed in 1944. The Sultanate was thereafter suspended and replaced by a Japanese council.^[20] During the Japanese occupation, the Dayak played a role in guerrilla warfare against the occupying forces, particularly in the Kapit Division. They temporarily revived headhunting of Japanese toward the end of the war.^[21] Allied Z Special Unit provided assistance to them. After theFall of Singapore, the Japanese sent several thousand British and Australian prisoners of war to camps in Borneo. At one of the worst sites, around Sandakan in Borneo, only six of some 2,500 prisoners survived.^[22] In 1945, the Japanese were defeated by the Allies.

Recent history[edit]

Borneo was the main site of the confrontation between Indonesia and Malaysia between 1962 and about 1969. The British Army was deployed against the Indonesians and communist revolts to gain control of the whole area. Before the formation of Malaysian Federation, the Philippines claimed that the eastern part of the Malaysian state of Sabah was within their territory. They based this on the history of the Sultanate of Sulu's leasing agreement with the British North Borneo Company.^{[citation needed]}

Demographics[edit]

The demonym for Borneo is Bornean or Bornese.

Borneo has 19.8 million inhabitants (in mid-2010), a population density of 26 inhabitants per square km. Most of the population lives in coastal cities, although the hinterland has small towns and villages along the rivers. The population consists mainly of Dayak ethnic groups, Malay, Banjar, Orang Ulu, Chinese and Kadazan-Dusun. The Chinese, who make up 29% of the population of Sarawak and 17% of total population in West Kalimantan, Indonesia^[23] are descendants of immigrants primarily from southeastern China.^[24]

In Kalimantan since the 1990s, the Indonesian government has undertaken an intense transmigration program; it financed the relocation to that area of poor, landless families from Java, Madura, and Bali. By 2001, transmigrants made up 21% of the population in Central Kalimantan.^[25] Since the 1990s, the indigenous Dayak and Malays have resisted encroachment by these migrants: violent conflict has occurred between some transmigrant and indigenous populations. In the 1999 Sambas riots, Dayaks and Malays joined together to massacre thousands of the Madurese migrants. In Kalimantan, thousands were killed in 2001 fighting between Madurese transmigrants and the Dayak people in theSampit conflict.^[26]

Largest cities[edit]

The following is a list of 20 largest cities in Borneo by population, based on 2010 census for Indonesia^[27][28] and 2010 census for Malaysia.^[29] Population data signifies number within official districts and does not include adjoining or nearby conurbation outside defined districts—such as, but not limited to, Kota Kinabalu and Banjarbaru. In other instances, the district area is much larger than the actual city it represents thereby "inflating" the population by including the rural population living further outside the actual city—such as, but not limited to, Tawau and Palangkaraya.^{[citation needed]}
