Borneo

Etymology

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 "váruṇa" (वरुण), meaning either "ocean" or the mythological Varuna, the Hindu 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 tropical weather).

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 or Brunei. In 1225 it was also mentioned by the Chinese official Chau Ju-Kua (趙汝适). The Javanese manuscript Nagarakretagama, written by Majapahit court poet Mpu Prapanca in 1365, mentioned the island as Nusa Tanjungnagara, which means the island of the Tanjungpura Kingdom.

Geography

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 and Karimata 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).

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 in East 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)).

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 guano accumulated to over 100 metres (330 ft) deep.

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 known as Wallace's Line between Asian and Australia-New Guinea biological regions.

Ecology

The Borneo rainforest is 140 million years old, making it one of the oldest rainforests in the world. There are about 15,000 species of flowering plants with 3,000 species of trees (267 species are dipterocarps), 221 species of terrestrial mammals and 420 species of resident birds in Borneo. There are about 440 freshwater fish species in Borneo (about the same as Sumatra and Java combined). 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 Borneo elephant, the eastern Sumatran rhinoceros, the Bornean clouded leopard, the Hose's palm civet and the dayak fruit bat.

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.

The WWFN has classified the island into seven distinct ecoregions. Most are lowland regions:

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.

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

Early history

According to ancient Chinese (977), Indian and Japanese manuscripts, western coastal cities of Borneo had become trading ports by the first millennium. 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. 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 6th century until about 1300.

One of the earliest evidence of Hindu influence in Southeast Asia were stone pillars which bear inscriptions in the Pallava script, found in Kutai along the Mahakam River in East Kalimantan, dating to around the second half of the 4th century. By the 14th century, Borneo became a vassal state of Majapahit based in present-day Indonesia. Muslims entered the island and converted many of the indigenous peoples to Islam.

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 say 1658), the Sultanate of Sulu received the eastern part of North Borneo from the Sultan of Brunei, after Sulu sent aid against a rebellion in Brunei.

Dutch and British control

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.

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.

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

World War II

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 of Sambas in Kalimantan was executed in 1944. The Sultanate was thereafter suspended and replaced by a Japanese council. 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. Allied Z Special Unit provided assistance to them. After the Fall 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. In 1945, the Japanese were defeated by the Allies.

Recent history

Borneo was the main site of the confrontation between Indonesia and Malaysia between 1962 until 1969, as the Indonesian President at the time, Sukarno, perceived the presence of the British in the area as trying to maintain the colonial government, mostly because of Sukarno's own intention to control the whole Borneo island under the Greater Indonesian political concept. To counter this, the British deployed their armed forces to guard their colonies against Indonesian and communist revolts. The Philippines claimed the eastern part of North Borneo (today Malaysian state of Sabah) as part of its territory. The Philippine government based their claim on the Sultanate of Sulu's cession agreement with the British North Borneo Company, which stated that the Sultanate had come under the jurisdiction of the Philippine republican administration, and as such, the republic should be the inheritor of the Sulu territories. The area in northern Borneo was also subjected to attacks by Moro Pirates since the 18th century, and militants such as the Abu Sayyaf since 2000. In 1962, the Brunei People's Party led by A.M. Azahari desired to reunify Brunei, Sarawak and North Borneo into one federation known as the North Borneo Federation (Malay: Kesatuan Negara Kalimantan Utara), where the Sultan of Brunei would be the head of state for the federation, though Azahari had his own intention to abolish the Brunei Monarchy and integrate Brunei, along with other British former colonies in Borneo into Indonesia. This directly led to the Brunei Revolt and forced Azahari to escape to Indonesia, his attempts having failed.

Demographics

The demonym for Borneo is Bornean.

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 are descendants of immigrants primarily from southeastern China.

In Kalimantan since the 1990s, the Indonesian government has undertaken an intense transmigration program; to that area it financed the relocation of poor, landless families from Java, Madura, and Bali. By 2001, transmigrants made up 21% of the population in Central Kalimantan. 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 the Sampit conflict.

Largest cities

The following is a list of 20 largest cities in Borneo by population, based on 2010 census for Indonesia and 2010 census for Malaysia. Population data signifies number within official districts and does not include adjoining or nearby conurbation outside defined districts—such as 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 Tawau and Palangkaraya.

Administration

The island of Borneo is divided administratively by three countries.
