Borneo is the third largest island in the world. It has an area of
743,330 km² (287,000 square miles), and is located at the centre of the Malay
archipelago and Indonesia. Borneo is considered to be part of the geographic region of
Southeast Asia. Administratively, this island is divided between Indonesia, Malaysia and Brunei.
Borneo is a Western appellation; used by the Dutch during the colonial period. In Indonesia today, the island is
referred to as Kalimantan. East Malaysia or Malaysian Borneo refers to the
States of Sabah and Sarawak.
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 is Java. To the east is the island of Sulawesi (Celebes). To the northeast is the Philippines.
Borneo's highest point is Mount Kinabalu in Sabah,
Malaysia, with an elevation of 4,095 m (13,435 ft) above sea
level. This makes it the world's third highest island.
The largest river systems are the Kapuas River, with approximately 1,143 km the longest
river in Indonesia, the Rajang River in Sarawak with some 563 km the longest river in
Malaysia, the Barito River about 880 km long and the Mahakam River about 980 km long.
Borneo is also known for its extensive cave systems. Clearwater cave has one of the world's longest underwater rivers.
Deer cave, thought to be the largest cave passage in the world, is home to over three million
bats and guano accumulated to over 100 metres high.
Administration
The Island of Borneo is divided administratively into:
History
Political divisions of Borneo
(yellow=Indonesia, brown=Malaysia, green=Brunei)
The Brunei Sultanate during its golden age from the 15th to 17th centuries ruled a large part
of northern Borneo. The northern Sulu Sultanate (1473–1899) retained influence in the
northern coasts and subsequently North Borneo was ceded in purchase to the British
North Borneo Company[1] in what is now Sabah. The company also exerted control on inland territories that
were inhabited by numerous tribes. In the 19th Century coastal areas ruled by the Brunei
Sultanate in the west of the island were gradually taken by the Brooke
dynasty.[2]
In the 15th century, the Majapahit rule exerted its influence in Borneo. Princess Junjung
Buih, the queen of the Hindu kingdom of Negara Dipa (situated in Candi Agung area of Amuntai)
married a Javanese prince, Prince Suryanata, and together they ruled the kingdom which is a tributary to the Majapahit Empire
(1365). In this way, it became a part of Nusantara. Along the way, the power of Negara Dipa
weakened and was replaced by the new court of Negara Daha. When Prince Samudra (Prince Suriansyah) of Negara Daha converted to
Islam and formed the Islamic kingdom of Banjar, it inherited some of the areas previously ruled by the Hindu kingdom of Negara
Daha.
By the 18th century, the area from Sambas to Berau were tributaries to the Banjar Kingdom, but this eventually shrunk to the size of what is now
South Kalimantan as a result of agreements with the Dutch. In the Karang Intan
Agreement during the reign of Prince Nata Dilaga (Susuhunan Nata Alam) (1808-1825), the Banjar Kingdom gave up its territories to
the Dutch Indies which included Bulungan, Kutai, Pasir, Pagatan and Kotawaringin. Other territories given up to the Dutch Indies
were Landak, Sambas, Sintang and Sukadana.
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 influences, in which indirectly set
apart the two parts of Borneo into British and Dutch controlled areas. China has had historical
trading links with the inhabitants of the island. Some of the Chinese beads and wares found their way deep into the interior of
Borneo.
Moreover in the 19th century, the Dutch admitted the founding of district kingdoms with native leaders who were under the
power of the Dutch (Indirect Bestuur). The Dutch assign a resident to head their rule over Kalimantan. List of the
residents and governors of Kalimantan:
- C.A. Kroesen (1898), resident
- C.J. Van Kempen (1924), resident
- J. De Haan (1924-1929), resident
- R. Koppenel (1929-1931), resident
- W.G. Morggeustrom (1933-1937), resident
- Dr. A. Haga (1938-1942), governor
- Pangeran Musa Ardi Kesuma (1942-1945), Ridzie
- Ir. Pangeran Muhammad Noor (1945), governor
Since 1938, Dutch-Borneo (Kalimantan) was one administrative territory under a governor (Governor Haga) whose seat was in
Banjarmasin. In 1957 following the independence of Indonesia, Kalimantan was divided into 3
provinces which is South Kalimantan, East Kalimantan and West Kalimantan. The province of Central Kalimantan separated from South
Kalimantan to have their own territory in 1958.
During the Second World War, Japanese forces gained control of Borneo (1941–45). They
decimated many local populations and Malay intellectuals, including the elimination of the Malay Sultanate of Sambas in Kalimantan [3]. Borneo was the main site of the confrontation between
Indonesia and Malaysia between 1962 and 1966, as well as the
communist revolts to gain control of the whole area. In recent times, the Philippines claimed that the Malaysian state of Sabah in north Borneo is within their territorial rights based on the Sultanate of Sulu's leasing agreement with the
North Borneo Company and had made several claims against Malaysia. Several other territorial claims were resolved at
The Hague international courts.
Ecology
Borneo is very rich in biodiversity compared to many other areas (MacKinnon et al.
1998). 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 (MacKinnon et al. 1998). It is also the centre of evolution and radiation of many endemic species of
plants and animals. The remaining Borneo rainforest is the only natural habitat for the
endangered Bornean Orangutan. It is also an important refuge for many endemic forest species, and the Asian Elephant, the Sumatran Rhinoceros and the Bornean Clouded
Leopard.
The World Wildlife Fund divides the island into seven distinct
ecoregions. The Borneo lowland rain forests cover most of the
island, with an area of 427,500 km². Other lowland ecoregions are the Borneo peat
swamp forests, the Kerangas or Sundaland heath forests, the Southwest Borneo freshwater swamp forests, and the Sunda Shelf mangroves. The
Borneo montane rain forests lie in the central highlands of the island, above the 1000 meter
elevation. The highest elevations of Mount Kinabalu are home to the Kinabalu montane alpine
meadows, an alpine shrubland notable for its numerous endemic species, including many orchids.
The island historically had extensive rainforest cover, but the area is shrinking rapidly
due to heavy logging for the needs of the Malaysian plywood
industry. One half of the annual tropical timber acquisition of the whole world comes from
Borneo. Furthermore, palm oil plantations are rapidly encroaching on the last remnants of
primary rainforest. The rainforest was also greatly destroyed due to the forest fires in 1997 to 1998 which were started by
people and coincided with an exceptional drought season of El Niño. During
the great fire, hotspots could be seen on satellite images and a haze was created that affected Brunei, Malaysia,
Indonesia and Singapore.
In order to combat overpopulation in Java, the Indonesian government started a massive
transmigration (transmigrasi) of poor farmers and landless peasants into Borneo
in the 70's and 80's, to farm the logged areas, albeit with little success as the fertility of the land has been removed with the
trees and what soil remains is washed away in tropical downpours.
Ethnic and biological diversity

There are over 30 ethnic groups living in Borneo, making the population of this island
one of the most varied of human social groups. The native ethnic groups are
Austronesians and their languages belong to the Malayo-Polynesian language family. Some ethnicities
are now represented by only 30-100 individuals and are threatened with extinction. Much culture, language, ethnomusic and
traditional knowledge has yet to be documented by anthropologists. Ancestral
knowledge of ethnobotany [4] and
ethnozoology [5] is useful in drug discovery (for example, bintangor plant for AIDS) or as future alternative food sources (such as sago starch for lactic acid production and sago maggots as a protein source).
Certain indigenous people (such as the Kayan, Kenyah,
Punan Bah and Penan) living on the island have been struggling for
decades for their right to preserve their environment from loggers and transmigrant settlers and colonists. Land reform is needed for future development in the face of rapid economic changes.
The type of rainforests found in Borneo include the high diversity mixed dipterocarp
forest, the rare peat swamp forests and heath
forest.
Researchers scouring swamps in the heart of Borneo island have discovered a venomous species of snake that can change its skin
color. Scientists named their find the Kapuas mud snake, and speculated it might only
occur in the Kapuas River drainage system.
World Wildlife Fund has stated that 361 animal and plant species have been
discovered in Borneo since 1996, underscoring its unparalleled biodiversity.[6] In
the 18 month period from July 2005 until December 2006, another 52 new species were found.
