The two parts are divided by the open waters of the South China Sea, and the country's land area is roughly 330,000 km². Its equatorial position gives it a hot, humid climate with high rainfall and two monsoon seasons, while its terrain runs from coastal plains and mangrove swamps to forested mountain ranges, with the highest peak, Mount Kinabalu, in Sabah.

It closes with the maritime and territorial disputes that shape the country's external geography and with the history of how the land and its waters have been mapped and described.

Peninsular Malaysia is the southern part of the Malay Peninsula in Mainland Southeast Asia. The other region, East Malaysia, is situated on the island of Borneo, where it comprises most of the northern part of Borneo. The two regions are divided by the South China Sea. Sources differ on the gap: one puts it at about 531 km, while another gives 640 kilometers (400 miles), so the figure should be read as approximate.\n\nThe country's total area is usually given as roughly 330,000 km². One widely used figure is 330,803 km² (127,724 sq mi), while other compilations report slightly smaller totals, which reflects differences in measurement methods. Peninsular Malaysia's area totals approximately 131,956 km2. It makes up nearly 40% of the total area of Malaysia; the other 60% is on the island of Borneo. Within East Malaysia, the State of Sabah covering 73,856 km2 and the State of Sarawak covering 124,989 km2 border Indonesian Kalimantan and the two enclaves of Brunei.\n\nMalaysia's land borders total about 2,669 km. Thailand: 506 km (314 mi) Indonesia: 1,782 km (1,107 mi) Brunei: 281 km (175 mi). The peninsula has its only land frontier with Thailand, to the north, while East Malaysia meets Indonesia and Brunei. Sabah and Sarawak are almost, but not quite, separated by Brunei and Indonesia. At the peninsula's southern end, a causeway and a bridge connect the country to Singapore, which lies just to the south of the peninsula. In the north-south direction, the peninsula is about 740 km long, and its maximum width is 322 kilometres (200 mi).\n\nThe southern limit of the peninsula is Tanjung Piai in Johor. Tanjung Piai is a cape in Pontian District, Johor, Malaysia. It is the southernmost point of Peninsular Malaysia and thus the most southern point of mainland Eurasia. Its position is given as a latitude of 1°16.00' North, and from the point, the skyline of Singapore is visible across the Johor Strait. Tanjung Piai is not the southernmost point of the whole country, because the only part of Malaysia as a whole that is further south is in Serian Division, the southernmost part of Sarawak." }, { "heading": "Administrative divisions and capital geography", "text": "Malaysia is a federation of thirteen states (negeri) and three federal territories (Wilayah Persekutuan). The states are Johor, Kedah, Kelantan, Malacca, Negeri Sembilan, Pahang, Penang, Perak, Perlis, Sabah, Sarawak, Selangor and Terengganu, and the federal territories are Kuala Lumpur, Putrajaya and Labuan. Eleven states and two federal territories lie on the Malay Peninsula and form Peninsular Malaysia. The other two states, Sabah and Sarawak, occupy the northern part of Borneo, and the island territory of Labuan lies just off Sabah. These three Borneo units are grouped as East Malaysia. The federal territories together are counted as a single unit in the national flag's fourteen stripes, a symbol of their status as a collective within the federal structure.\n\nThe two regions differ in how power is organised. In the states, the federal government and each state government share authority, and each state has its own government. The federal territories have no state governments and are run directly by federal ministries and the Federal Territories Department. Among the peninsular states, nine have hereditary rulers, such as sultans, as their heads of state. Malacca, Penang, Sabah and Sarawak instead have governors appointed by the king. The capitals of the Borneo states are Kota Kinabalu in Sabah and Kuching in Sarawak.\n\nSabah and Sarawak joined the federation on special terms. The Malaysia Agreement 1963 was signed in London on 9 July 1963 by the United Kingdom, the Federation of Malaya, North Borneo, Sarawak and Singapore. Its provisions were built into the constitution when Malaysia was formed on 16 September 1963. Sabah's negotiators secured 20 points of protection, and Sarawak secured 18. These protections gave the two states a degree of self-government beyond that of the peninsular states, including separate immigration controls. Malaysians from the peninsula must carry a passport or identity card when visiting East Malaysia. Land and immigration were among the areas that the agreement aimed to keep under local control. In practice, the autonomy has developed unevenly. Sarawak has built up greater self-governance, while Sabah's politics have remained more closely tied to the priorities of the peninsula, and both states continue to dispute the extent to which federal centralisation has eroded the original terms.\n\nKuala Lumpur is the national capital under the constitution and the country's largest city. It is also the seat of Parliament and the residence of the head of state, the Yang di-Pertuan Agong, and it serves as the main commercial and financial centre. Kuala Lumpur separated from Selangor to become a federal territory in 1974, and it is now enclosed by Selangor territory. Putrajaya, about 25 km south of Kuala Lumpur, is the federal administrative centre. Its development began in the 1990s to relieve congestion in Kuala Lumpur, where government offices had been scattered across the city. Putrajaya was built largely on former rubber and oil palm estates and was planned as a garden city with a large artificial lake and extensive parks and wetlands. The Prime Minister's Office moved there in 1999, and the seat of the federal government was moved in the same period. The date when Putrajaya became a federal territory is given as 2001 in some sources, and the judiciary's move to the city is dated to 2003 in others, so the exact sequence of relocations varies by account.\n\nKuala Lumpur and Putrajaya together form the core of the Klang Valley, the urban region centred on the capital and largely located in Selangor, and the planned southward corridor from Kuala Lumpur was intended to link the two areas. Labuan is a separate case. It is an island off the coast of Sabah, and it was part of North Borneo before becoming a federal territory on 16 April 1984. The island was developed as an offshore financial centre, and its offshore finance centre was established around 1990. Its status as a federal territory means that it is administered by the national government rather than by Sabah." }, { "heading": "Geological formation and tectonic setting", "text": "Peninsular Malaysia sits on the Sunda Shelf, the south-eastern extension of the continental shelf of mainland Southeast Asia, which covers about 1.85 million square kilometres (Sunda Shelf). During the Last Glacial Maximum, sea level was lowered by about 100 metres, which fully exposed the Sunda Shelf and joined the land masses that are now separated by shallow seas, so the peninsula was once physically connected to Borneo, Sumatra and Java.\n\nBeneath the peninsula lies older continental crust. Charles Hutchison's influential division of the peninsula recognises four major tectonic regions: the Western Stable Shelf, the Main Range Belt, the Central Graben and the Eastern Belt. Rock geochemistry and strontium isotope ratios indicate a well-established continental basement under the Main Range and Western Stable Shelf, which is not the case for the other two regions. The Western Belt is built from Ordovician to Permian sedimentary and metamorphic rocks, intruded by Late Triassic S-type granites of the Main Range Granite Province. The Eastern Belt, by contrast, belongs to the Indochina Block and is dominated by Permo-Triassic volcanic rocks and I-type granites (mountain ranges and basins were shaped by repeated orogenic episodes).\n\nThe Main Range, which forms the central spine of the peninsula, is the product of granite emplacement. Collisional crustal thickening produced the Main Range S-type granitoids, which intruded the Western Belt as well as the Bentong-Raub suture zone. These granites are coarse and porphyritic, and the Main Range Belt appears to have been uplifted by several kilometres since the Triassic, a conclusion drawn from discordant radiometric dates and the absence of contact-metamorphic aureoles around the intrusions. Zircon ages of the Main Range granitoids fall between roughly 230 and 180 million years, and the suite is so well documented that the Main Range Granite became the world standard for collisional S-type granite. The same S-type granites are also the source of the peninsula's tin deposits, although the Eastern Belt's different basement produced a different style of mineralisation.\n\nBorneo has a younger and more dramatic record. The Crocker Range in Sabah is a collisional mountain belt formed when the proto-South China Sea was subducted beneath northern Borneo between the Eocene and the Early Miocene. Its sedimentary rocks, which belong to the Crocker Formation, are strongly deformed in the Kinabalu area, folded, faulted and commonly steeply dipping. Mount Kinabalu is the summit of a granite pluton that intruded this deformed succession and is the only pluton known to do so. Estimates of its age vary between sources: zircon growth-zone analysis indicates crystallisation between about 7.85 and 7.22 million years ago, with the whole body emplaced in under 800,000 years, while some popular accounts give ages of roughly 8 million or 10 million years. The pluton has been exhumed rapidly, with peak exhumation rates above 7 mm per year reported for the latest Miocene to early Pliocene, which exposed the granite at the 4,095-metre summit.\n\nSeismic activity is low across most of Malaysia because the country lies far from active plate boundaries. The most significant exception is the Ranau earthquake of 5 June 2015 in Sabah. It was a moment magnitude 6.0 event with a shallow hypocentre roughly 10 kilometres deep beneath the Mount Kinabalu area, and analyses attribute it to rupture of a blind normal fault within the Crocker fault system, which did not reach the surface. Its occurrence was described as a surprise because it lay well away from any plate margin. The shaking killed 18 climbers on the mountain, damaged the summit formation known as the Donkey's Ears, and triggered landslides and mudslides that affected nearby residents and disrupted water supplies. Sources differ on the magnitude of the previous strongest event in Malaysia, the 1976 Lahad Datu earthquake, which is given as 5.8 in some reports and Mw 6.2 in scientific studies. One study also records three events above Mw 5.0 in Ranau district, in 1966, 1991 and 2015, and modelling suggests that a larger event could affect Kota Kinabalu, the state capital." }, { "heading": "Landforms and relief", "text": "Peninsular Malaysia is built around a spine of upland ranges. The Main Range, also called the Titiwangsa Mountains, forms the central axis. The Tahan Range parallels the Main Range, about 60 miles (97 km) west of it, and extends south from Mount Tahan for about 75 miles (120 km) across the tablelands of Terengganu. Between these uplands and the sea lie lowlands that differ sharply by side. The west coast is backed by broad alluvial plains, reached by long, gently sloping river valleys. The east coast has a much narrower strip of lowland, and the hills and ranges reach the shoreline more quickly. Along the eastern seaboard, the Pantai Timur Range in inland Besut District, Terengganu is a subrange of the Tenasserim Hills whose highest point, Mount Lawit, reaches 1,519 m.\n\nThe highest point on the peninsula is Gunung Tahan. At 2,187 m, Gunung Tahan is the highest peak in Peninsular Malaysia and is located in the Taman Negara National Park. Its summit forms part of a chain of high ground, and its prominence has been reported inconsistently. One source gives a prominence of 2,135 m, another gives 2,140 m, and a third lists Proportional Prominence 2,147 m. The next-highest peaks are also close in height. Mount Korbu is also the second highest mountain in Peninsular Malaysia, standing at 2,183 metres, and its summit is 2,181 m (7,156 ft) above sea level, making it the highest mountain in the state of Kelantan, and the third highest in Peninsular Malaysia, behind Tahan and Korbu. Mount Gayong, at 2,173 m, is listed as the fourth-highest peak. In Sabah, the highest and most prominent peak in Malaysia is Gunung Kinabalu, which stands at 4,095 m (13,435 ft) in elevation.\n\nThe Main Range also contains highland basins. The best known is the Cameron Highlands, a plateau in Pahang. It comprises a cool highland plateau (elevation 4,750 feet [1,448 metres]), developed by the British in the 1940s as a hill station. Reported elevations vary by source. One description puts the district at 1,100 to 1,600 meters above sea level, while a topographic survey gives an average of 1,400 m. The town of Tanah Rata is at 1,440 metres (4,720 ft). The altitude keeps the basin cooler than the surrounding lowlands. One tourism description states that temperatures there are no higher than 25 °C and rarely falling below 12 °C year round.\n\nSarawak's most distinctive relief is karst. The Gunung Mulu karst in northern Sarawak is built from limestone that rises above surrounding sandstone terrain. It is an escarpment of Miocene Melinau Limestone dipping steeply to the north-west, and Mount Api and Mount Benarat each rise more than 1000 m above the plains of the Melinau River. Erosion has carved the limestone into dramatic forms. Eroded from the thick limestone bedrock over hundreds of thousands of years, these karst features hint at the otherworldly caverns belowground. Water draining off the sandstone also shaped the limestone. Researchers describe how the drainage off the sandstone also migrated laterally along the contact with the limestone to produce a series of very large cavities, whose roof collapse produced a series of very large dolines or tiankeng (sky windows). Among the caves, the world's largest underground chamber (the Sarawak Chamber) is the best-known, and the Park covers 52,865 hectares; 100 km inland from the coastal port of Miri in Sarawak." }, { "heading": "Coasts, islands, and marine environment", "text": "Malaysia's peninsular coastlines differ sharply. The west coast faces the Strait of Malacca, where muddy beaches and wide river plains dominate. Mud accounts for roughly seven-tenths of the west-coast shoreline, and the remainder is sand broken up by capes and headlands of granite and sandstone (About 72% of the coastline in West Peninsular Malaysia is made up of mud coasts, while the rest is sand coasts interspersed with capes, promontories and headlands of granite and sandstone.). The east coast, which faces the South China Sea, is narrower and has a different profile. Its shoreline is interspersed with sandy beaches and a few picturesque lagoons, and some of its beaches are quite narrow. Estimates of the total coastline vary by source. One figure gives 4,675 kilometers (2,905 miles), while another puts the length near 4,800 km.\n\nBeaches and mangroves together make up most of the shoreline. About half the coast is beaches, and slightly less than half is fringed with mangrove forest (About half the coastline is beaches and slightly less than half is fringed with mangrove forest.). The mangrove belt is densest where muddy sediment accumulates. Mangroves perform several coastal functions, including shoreline stabilization, climate regulation, water quality maintenance, nursery sites for fishes and invertebrates. Recorded areas differ by region. Peninsular Malaysia held total mangrove areas of 98,848 hectares in 2012, while the State of Sabah has the largest area of mangrove forest in the country, at 333,019 hectares within permanent reserved forests. Sarawak's total was 112,165 hectares (the total mangrove forest area in Sarawak in 2012 is 112,165 hectares). National totals are contested. One Forest Research Institute of Malaysia series gives 642,063 ha and 629,038 ha, respectively for 2000 and 2017, while a global dataset reports a total extent of 524,575 ha of mangroves in 2020, with acknowledged classification errors.\n\nMangrove loss on the peninsula has been measurable. One estimate states that starting from 1990 to 2010, Peninsular Malaysia mangrove lost is at 1% rate (approximately 1282 ha) annually, mainly due to agriculture, aquaculture land conversion and coastal erosion. Long-term management can offset some of this pressure. The Matang reserve on the Perak coast, spanning some 40,000 hectares, has been managed since 1904, and after more than a century of continuous and systematic management, Matang mangroves have only lost 250 hectares.\n\nOffshore, the marine environment includes coral reefs, seagrass beds and numerous small islands. The peninsula's east coast has numerous unspoilt islands. The most significant marine protected area is in Sabah. Tun Mustapha Park was formally established on 19 May 2016 and covers a marine area of 898,762.76 hectares (ha) across three districts (i.e. Kudat, Kota Marudu and Pitas). It contains more than 50 islands and islets. The park's figure has shifted over time, since one earlier proposal described it as 1.6 million hectares of seascape. Its reefs are notable for diversity: the new park is home to more than 250 species of hard coral and around 360 species of fish. The park also serves as critical breeding sites and habitats for various marine species and also migratory animals such as turtles, marine mammals, whale sharks. The park sits within the Coral Triangle, and its waters are where the Sulu and South China seas meet. Sabah's wider marine park system is growing, and seven percent of the seas in Sabah, equivalent to two million hectares, have been gazetted as marine parks.\n\nCoastal sediment and shoreline change strongly affect settlement and farming on low-lying shores, though the specific local rates are not covered here. Fine sediment carried by rivers builds out mud flats, and mangroves trap that material and stabilize it. When river sediment supply falls, or when mangrove cover is cleared for ponds and farms, the same shoreline can begin to retreat. Monsoon waves and tidal currents reshape east-coast beaches each season, which can shift sand between the beach and offshore bars. Low-lying farmland, aquaculture ponds and village sites behind the shore are most exposed to these changes, and they are also the places where sea-level rise and storm surges would have the greatest effect. Managing these processes therefore depends on keeping mangrove belts, estuaries and river deltas functioning rather than reclaiming them." }, { "heading": "Rivers, lakes, and water resources", "text": "Malaysia's rivers drain steep interior ranges onto coastal plains, and in both regions they have long been the main routes into the interior. Their importance is greatest in East Malaysia, where roads are sparse.\n\nThe Rajang in Sarawak is generally counted as the country's longest river, but published figures differ. One popular reference gives about 565 km and ranks it seventh-longest on Borneo, the longest and largest by volume in Malaysia. The Wikipedia infobox instead lists 770 km and a drainage basin of about 50,707 km². Its headwaters lie in the Iran Mountains, and the river reaches the South China Sea after passing Kapit . Sarawak's gazetted rivers number 35 and total about 5,000 km, and approximately 3,300 km are navigable. Ocean-going vessels can reach Sibu, roughly 130 km upstream, and shallow-draft craft continue about 160 km further to Kapit . Because much of Sarawak's population lives in the interior and along the coast, these waterways do the work that roads and rail perform in the western states . Logs and farm produce also travel downriver to deep-water export ports .\n\nOn the Malay Peninsula the Pahang is the longest river, at 459 km . Its two main tributaries are the Jelai, which rises in the Titiwangsa Range near Cameron Highlands, and the Tembeling, which begins in the Pantai Timur hills. They meet at Kuala Tembeling . Reported basin areas vary, from about 25,600 km² to 29,300 km² , and some sources give a main-stem length of 440 km . The basin's upper course is steep, while its lower course is flat and swampy . Flooding is common in the wet season, driven by the monsoon , and the northeast monsoon from November to March is the main period of concern . Annual rainfall across the basin is about 2,170 mm .\n\nTasik Chini in Pahang is the second-largest natural freshwater lake on the peninsula and is made up of a series of 12 lakes . Several rivers feed it, including the Melai, Jemberau, and Gumum, and water leaves through the Sungai Chini into the Pahang . Because inflows are usually small, the lake's water levels fall and navigation is disrupted . The outflow river has been dammed to keep the lake deep through the dry season . A water balance estimate indicates six months of deficit and six months of surplus each year . The lake is shallow, with an average depth of 1.5 m that varies seasonally between 0.5 and 2.2 m . Researchers classify it as a tropical floodpulse wetland, in which the wet and dry seasons drive its organic matter cycles . Mining, deforestation, and farming in the surrounding catchment have degraded water quality .\n\nWater supply depends mainly on surface sources. One widely cited general reference attributes about 98% of supply to rivers and streams, with groundwater providing the remainder . The balance between abundant rainfall and seasonal shortage is a recurring theme. Tasik Chini's catchment receives between about 1,488 mm and 3,071 mm of rain a year, averaging 2,235 mm , yet its water budget still turns negative for half the year. Drought years can drop lake levels sharply. Records from the late 1930s show a prolonged dry period that lowered the Tasik Chini level and cut off a sub-basin near the outlet .\n\nPeat swamps, which cover much of the low coastal ground in Sarawak and parts of the peninsula's western coast, act as water stores that release water slowly. Their surface holds rainfall during the wet season and feeds streams during dry spells. Drainage for agriculture or plantations lowers the water table in the peat. The organic soil then shrinks and dries, so it loses much of its capacity to hold water. Subsidence lowers the land surface, which increases flooding in low-lying areas, particularly where high tides meet heavy rain. Dry peat is also prone to fire, which links drainage to the regional haze problem." }, { "heading": "Climate", "text": "Malaysia has an equatorial tropical climate, with little variation in temperature through the year and humidity that remains high almost everywhere. Coastal areas are sunny, with temperatures ranging between 23 and 32 °C, and rainfall of 10 to 30 centimetres a month. The lowlands have a similar temperature, but follow a more distinctive rainfall pattern and show very high humidity levels. At Kuala Lumpur airport, the 1991–2020 normals give an average annual rainfall of about 2,208 mm, and the station's extremes run from 1963 to the present.\n\nSeasonal change is driven mainly by two monsoon wind systems rather than by temperature (see monsoon). The northeast monsoon, usually from November to March, brings the main rainy season, especially to the east coast of Peninsular Malaysia, western Sarawak and eastern Sabah. Cold-air surges from Asia can strengthen winds, roughen seas and support prolonged heavy rain along exposed coasts. The Titiwangsa range shelters the west coast and Kuala Lumpur from much of this rain, although the capital still receives showers in these months. The southwest monsoon, from late May to September, brings relatively drier conditions across much of Malaysia, but it delivers the wet season to the west coast, where Langkawi's wettest months are September and October. Sources differ on the span of the southwest monsoon: one gives April to October, which is a broader window than the late-May-to-September period used by most other sources. Between the two monsoons, short inter-monsoon windows, typically April to May and October to November, bring convective thunderstorms that can appear anywhere in the country, usually as brief afternoon downpours.\n\nThe highlands differ from the lowlands in temperature, humidity and cloud. The highlands are cooler and wetter, and display a greater temperature variation. A large amount of cloud cover is present over the highlands, which have humidity levels that do not fall below 75%. Cooling at altitude is strong enough to matter in practice: in 2018, the temperature in Cameron Highlands dipped to 15ºC, a value far below the lowland norm.\n\nThe national temperature extremes are well documented but have uneven sources. The highest temperature was recorded at Chuping, Perlis on 9 April 1998 at 40.1 °C (104.2 °F). This figure is repeated in later official and press material; in 2026 the Meteorological Department said maximum temperatures expected to exceed the local record of 40.1 degrees Celsius set in 1998 in Chuping. Earlier news reports from the 2016 El Niño period recorded 37 degrees Celsius at Alor Setar and 36 degrees Celsius at Chuping, which were high readings but well short of the 1998 record. Encyclopedic sources on Chuping likewise describe the town as the hottest place in the country, at times going beyond 36 degrees Celsius.\n\nThe national cold record is less certain in its provenance. Wikipedia-style summaries give the lowest temperature ever recorded in Malaysia on Mount Kinabalu at −5 °C (23 °F) on 7 April 2023. News coverage of the same night describes readings ranged from -3°C to -5°C, recorded between 2.30am and 7am, and the information came from observations shared by Sabah Parks staff rather than from a published meteorological series. Sub-zero nights on the peak are not unusual: the same report notes that similar episodes occurred in 2018, 1993 and 1975, and snowfall has been reported on the mountain in 1975, 1993, 2018, and 2022. Because Malaysia lies so close to the equator, these high-altitude events are rare exceptions to the warm lowland pattern.\n\nTemperatures are also trending upward. The Meteorological Department reports that Malaysia has seen average temperatures climb since the 1980s, with the highest peaks often recorded during \"super\" El Niño events, and it has forecast that the next El Niño, peaking between March and May 2027, could push maxima beyond the 1998 record (see El Niño and climate change)." }, { "heading": "Vegetation and ecoregions", "text": "Malaysia's plant cover is arranged mainly by elevation, soil type and water regime. Lowland dipterocarp forest is the most widespread forest type below about 300 m. Together with hill dipterocarp forest, it makes up the main forest type in the country. In its primary state, the canopy sits at 45 m, with emergent trees reaching 60 m, and about half of the upper-story trees belong to the Dipterocarpaceae family. Hill dipterocarp forest is the most extensive forest type in Peninsular Malaysia and exists at 300 to 750 meters. Above it, upper dipterocarp forest occurs at 750 to 1,200 m, and forests at roughly 1,200 to 1,500 m are dominated by oaks, chestnuts and laurels, with dipterocarps becoming scarce. Forest classification differs between regions: in Sabah, lowland dipterocarp forest is subdivided by species dominance, while in Sarawak the lowland and hill forests are grouped as mixed dipterocarp forest.\n\nHeath forest, locally called kerangas, grows on nutrient-poor, free-draining soils and forms a distinct ecoregion. The Sundaland heath forests, also known as Kerangas forest cover about 76,130 km² across Indonesia and Malaysia. In Malaysia, smaller patches also occur on limestone and on quartz ridges. Peat swamp forest develops where waterlogged soils prevent dead leaves and wood from fully decomposing, which over time creates thick layer of acidic peat. On the peninsula, this ecoregion covers about 3,600 km² on both coasts. Its dipterocarps dominate the canopy, and although the forest is less diverse than the surrounding rainforest, it shelters many endangered animals. Peat swamps have typically formed behind mangrove belts, where river sediment and organic debris accumulate over centuries.\n\nCoastal vegetation is shaped by tides and salinity. A 1998 national assessment recorded about 0.53 million hectares of mangrove forest, compared with about 1.46 million hectares of peat and freshwater swamp forest. Beach forests are found along the east coast of Peninsular Malaysia, with mangroves more common along the western coasts. Among the mangrove swamps, brackish water vegetation is common, especially in areas where fresh and saltwater mixes during high tides. Nipa palm, which forms dense stands along tidal creeks and estuary margins, is a characteristic element of these brackish zones.\n\nMount Kinabalu in Sabah provides the clearest example of altitudinal zonation. Its altitudinal range, from 152 m to 4,095 m, takes in rich tropical lowland and hill rainforest (35% of the park) to tropical montane forest (37%), and sub-alpine forest and scrub at the highest elevations. A transect study between 600 and 3,400 m identified four discrete zones, each defined by a distinct group of canopy species: lowland (below 1,200 m), lower montane (1,200 to about 2,000–2,350 m), upper montane (to about 2,800 m), and subalpine (to the forest line near 3,400 m). These boundaries track soil changes, from lowland Oxisols through montane Histosol–Spodosol complexes to subalpine Inceptisols. Above the forest line, the summit area carries low, leaf-reduced scrub. The leaf-size spectrum of forest communities changes abruptly near 3,200 m, which has been attributed to drier conditions at high elevation. Ultramafic (serpentine) rocks cover about 16% of the park and have vegetation specific to this substrate.\n\nPlant diversity is high across the country and particularly in the lowland forests, which sustain the highest biological diversity compared to any other vegetation type. Malaysia is recognized as a megadiverse country and a biodiversity hotspot, and is home to approximately 9,030 vascular plant species, encompassing 248 families and 1,651 genera. Orchids are among the best-documented groups. A 2017 checklist lists 972 species in 146 genera from Peninsular Malaysia, while other estimates give about 978 species and about 1,026 species in 155 genera, reflecting different taxonomic treatments. Borneo's share is far larger, with roughly 3,000 orchid species in Sabah and Sarawak, and Orchidaceae is the most abundant flowering plant family in Malaysia." }, { "heading": "Biodiversity and endemic wildlife", "text": "Malaysia's animal communities divide broadly between the Malay Peninsula and Borneo. Both sit on the Sunda Shelf, which was joined to mainland Asia when sea levels were low during the Pleistocene, so many species are shared across the South China Sea. Still, the two regions have different large-mammal assemblages. The peninsula's fauna resembles that of mainland Southeast Asia, with Asian elephants, Malayan tapirs and Malayan tigers. Sabah and Sarawak hold Bornean forms such as the Bornean orangutan, the only great ape living in Malaysian territory, and the Bornean pygmy elephant, a smaller population of the Asian elephant. The Malayan sun bear, the smallest bear species, occurs in both regions and is listed as Vulnerable. Primates are the clearest Borneo signal: the orangutan, the proboscis monkey and the Bornean tarsier are found there and nowhere on the peninsula.\n\nThe Malayan tiger (Panthera tigris jacksoni) is the most closely watched species. It lives only in Peninsular Malaysia, mainly in the south and centre. A nation-wide tiger survey carried out between 2016 and 2020 recorded fewer than 150 tigers. By comparison, about 3,000 tigers were estimated to roam the forests of Peninsular Malaysia seventy years ago, which shows how sharply the population has fallen. The main pressures are poaching and the illegal wildlife trade, habitat loss and fragmentation, and the depletion of the deer and wild pig prey on which tigers depend. Tigers reproduce slowly, with adult females typically raising a litter only every two years, so each lost animal has a large effect on recovery. The Malayan gharial (Tomistoma schlegelii), a slender-snouted crocodilian, is another threatened species of the region's rivers and swamps. It needs slow-moving blackwater rivers, undisturbed riverbank forest and wetlands with intact fish stocks, and it is vulnerable to dam construction, riverbank clearance and fishing nets.\n\nThe largest protected area on the peninsula is Taman Negara, which spans Pahang, Kelantan and Terengganu. Its figures for birds, mammals and plants differ by source, and the counts should be treated as approximate. One widely cited summary gives 10,000 plants, 675 birds, 270 reptiles, 250 freshwater fish and 200 mammals, while a tourism guide reports more than 350 bird species. The park supports Malayan tapirs, sun bears, clouded leopards and gaurs, and it is one of the few places where a viable tiger population is still thought to persist. Gunung Mulu National Park in Sarawak is the Bornean counterpart. Its UNESCO listing describes seventeen vegetation zones, exhibiting some 3,500 species of vascular plants, and the animal inventories also vary: one account gives 81 mammal species and at least 270 bird species, while an official park page lists 116 mammals and 305 birds. Park boundaries follow terrain and the limestone and sandstone landforms rather than the ranges of wide-ranging animals. A reserve of 4,000 to 5,000 square kilometres can protect a breeding core for tigers, elephants and gaurs, but these animals move across forest that falls outside the boundary. Connecting forest corridors and buffer zones are therefore critical for populations to remain viable.\n\nBird and insect diversity is high in both regions, and the distribution of many species follows the major rivers. Large lowland rivers, such as those draining Borneo's interior, can separate populations of forest birds and small mammals, and the river systems of Sarawak and Sabah have been treated as barriers in biogeographical studies. Mulu's inventories give a sense of the richness: one park page lists 262 bird species, 281 butterfly species and 458 ant species, although these figures are not drawn from a single survey. Such barrier effects help explain why Borneo's endemic bird and insect populations are often divided into localized forms, a pattern that connects to the classic biogeographical work of Alfred Russel Wallace and to the Sundaland region as a whole." }, { "heading": "Land use, forest cover, and agriculture", "text": "Estimates of Malaysia's forest cover differ according to the data source and the definition of \"forest\" used. Peninsular Malaysia shows the clearest long-term decline. A mapping study found that about 64% of the peninsula's land was forested in 1972 (the same study digitized forest maps from 1972 and 1982 to track change). Over a longer span, the peninsula's forest area fell from roughly 9.7 million hectares in 1950 to about 5.73 million hectares in 2019 (9.7 million hectares in 1950; 5.73 million remaining in 2019). Clearing appears to have peaked in the 1960s or 1970s, when loggers and developers removed up to 275,000 hectares a year, about 2% of the land area (loss at this rate likely peaked in the 1960s or 1970s). The National Forestry Policy of 1978 responded by reclassifying large forest areas as permanent reserve forests, and by 1990 78% of Peninsular Malaysia's forests were gazetted as permanent reserve forests. In 1992 the government set a goal of keeping at least half of the country's land under forest cover, a target that some analysts regard as far above international benchmarks.\n\nRecent figures disagree considerably. The Forestry Department reports that the peninsula lost about 133,000 hectares of forest between 2002 and 2021, with cover falling to 43.47% (the department recorded roughly 133,000 hectares lost, with forest cover slipping to 43.47%). Satellite-based analysis by Global Forest Watch found a far larger loss of primary forest on the peninsula over 2001–2019, about 725,613 hectares, compared with an official loss of about 130,000 hectares over the same period. For the country as a whole, the ministry put 2017 forest cover at 55.52 per cent of the total land area, while a civil-society analysis projected that cover could fall to about 47% if approved future clearing proceeded. Gross loss measured by sampled Landsat imagery was also substantial: 4.25 million hectares lost during 1990–2000 and 3.20 million hectares during 2000–2005.\n\nTimber extraction has altered forest structure as much as it has reduced total area. In a 1972–1982 study of the peninsula, most of the change in primary hill forest area came from conversion to logged forests, and about 40% of the primary hill forest present in 1972 had been converted to non-forest use or logged by the end of the period (about 40% of primary hill forest present in 1972 was converted to nonforest use or logged). Selective logging also shifts land classification: the decrease in forest area is largely due to primary forest being reclassified as \"other naturally regenerated forest\" because of selective logging and other human interventions. Because logging has a long history, many degraded areas could in principle be reforested for carbon storage and ecosystem services, while the loss of old-growth stands raises carbon emissions because those forests store more carbon per hectare.\n\nOil palm is the dominant plantation crop. Commercial planting began in 1917, but large-scale cultivation commenced only around the 1960s following the Government's crop diversification programme to reduce the country's dependence on rubber. Planted area rose from 2.03 million hectares in 1990 to 3.50 million hectares in 2001, and by 2012 it reached about 5.10 million hectares, or 15.4% of the total land area. Expansion followed different paths in the two regions: much of the early expansion of oil palm in Peninsular Malaysia replaced existing rubber plantations, but most of the oil palm in Sabah and Sarawak was planted on land that had previously been forested. As one example of land clearance, in 2004 the Sabah Forestry Department approved the conversion of 109,600 ha of natural forest inside Kalabakan Forest Reserve and Gunung Rara Forest Reserve for oil palm. Area estimates also vary: one satellite mapping of 2017 counted about 2.95 million hectares (2.11 million on the peninsula and 0.84 million in Sabah and Sarawak), a figure well below the roughly 5.81 million hectares reported in official-style series for the same year. Later satellite work suggests that planted area has been relatively stable during the study period, consistent with the maturity of Malaysia's oil palm sector, with Sabah and Sarawak ranking as the largest producing states.\n\nRubber has a longer history in the country. Trees were first planted in British Malaya in 1876, and by 1922 the area dedicated to rubber had reached 2,260,000 acres. Rubber and oil palm together make up most of the non-forest tree-crop area, which one government-linked assessment put at 6.06 million hectares of agricultural tree crops, primarily oil palm and rubber plantations.\n\nAgricultural land occupies a modest share of the country. Recent World Bank-based figures put arable land at about 2.4% of the total, with permanent crops at about 22.7% and agricultural land overall at about 26.1% (arable land 2.4%, permanent crops 22.7%, agricultural land 26.1%, all 2023 estimates). Older estimates from 2001 gave a different split, with arable land at 5.5% and permanent crops at 17.6%, a gap that reflects both the change over time and differences in classification. Irrigation is limited, since only about five percent of Malaysia's cropland is actually irrigated. The cooler upland zones, such as the Cameron Highlands, are used for vegetables, tea, and flowers rather than the lowland tree crops that dominate most of the country." }, { "heading": "Natural hazards and environmental pressures", "text": "Flooding is the most widespread recurring hazard. Most of the large seasonal floods come from the Northeast Monsoon, which usually runs from about November to March. Its rain, which forms as cold air flows from Siberia meet low-pressure systems, falls heavily on the east coast of the peninsula, particularly Kelantan, Terengganu, Pahang and eastern Johor, and also on western Sarawak and eastern Sabah. These floods build over several days and can cover large areas, and they are worst when intense rain coincides with a high tide, which holds back drainage from rivers and low-lying land. The January–February 2015 floods in Sarawak and Sabah caused damage estimated at about US$1.03 billion and forced around 13,000 people from their homes. The 2024–25 season again hit Kelantan, Terengganu, Pahang and Johor hardest, with displacement and long disruption. In the Klang Valley, the risk is different: short, intense storms, especially in the inter-monsoon periods, produce flash floods that overwhelm urban drains.\n\nLandslides and erosion are concentrated in steep terrain. Intensive tropical weathering produces deep or shallow soils depending on the parent rock, and where rain runs off exposed slopes, surface erosion follows; where it soaks into the soil profile, slope failure can occur. Slopes steeper than about 25 degrees are especially vulnerable in heavy rain, and removing vegetation further weakens them. The Batang Kali landslide in Selangor on 16 December 2022 killed people after heavy rain saturated soil on steep ground. Clearing forest for cropland or plantations permanently reduces the root strength that binds shallow soils, whereas timber harvesting weakens slopes gradually, with landslide erosion often increasing several years after logging. Plot studies show how much cover matters: bare soil lost roughly 4.7 tonnes per hectare in a monitored east-coast trial, compared with under 1 tonne where litter and undergrowth remained. Sediment from highland erosion has also reached rivers and hydroelectric works, as in the Cameron Highlands, where granite-derived sand was reported to be damaging generator blades.\n\nTransboundary haze is a recurring problem linked to fires in Indonesia. Slash-and-burn clearing and fires on peatland are carried by prevailing winds across the border, degrading air quality in Malaysia. Drained peat is especially flammable and can smoulder underground for months. In 2005 a state of emergency was declared at Port Klang when the Air Pollutant Index passed 500. The 2015 haze, the worst episode in over a decade before 2026, exposed tens of millions of people to smoke. In August and September 2026, smoke from fires in West Kalimantan and other parts of Indonesian Borneo settled over Sarawak for much of the month. Schools in Tebedu were closed after the index exceeded 200, and an emergency was declared in Serian in early September, when the index reached 521. Sarawak was the worst-hit state, though smoke also reached the peninsula, Brunei and Singapore. Indonesian officials have at times denied that their fires caused haze in Malaysia, and such disputes recur. Fire risk rises sharply in El Niño years, when dry-season rainfall is much lower.\n\nDrought affects Malaysia less often than floods but can be severe. The Southwest Monsoon brings much drier weather, and most states receive only about 100 to 150 mm of rain a month in that period. Dryness on the peninsula is partly attributed to the rain shadow of the mountains of Sumatra, while Sabah is comparatively wet. A moderate or strong El Niño can reduce rainfall in Sabah and Sarawak well below normal. In 2014, after a month-long dry spell, Kuala Lumpur and surrounding areas faced water rationing, and cloud seeding was used over dams and catchments. Prolonged dryness lowers river flows and reservoir levels, which strains water supply systems, and it also dries peat, making it more prone to the fires that generate haze." }, { "heading": "Climate change impacts and adaptation", "text": "Observed warming and rainfall change\n\nSurface temperatures in the three regions rose by roughly 0.14 to 0.25 °C per decade over 1970–2013. Temperature projections are more pronounced. Under the highest-emission pathway, RCP8.5, national average temperatures could rise by about 3.1 °C by the 2090s, a figure that sits slightly below the global mean increase. A regional modelling study that used older SRES scenarios put end-of-century warming at about 1.7 to 4.2 °C, depending on the scenario and season. Rainfall projections show large spatial and seasonal variation, with a drier tendency in boreal winter and spring and a wetter tendency in summer and autumn. One peninsular study projected a decrease of about 20–40% in rainfall from December to May over Peninsular Malaysia and Borneo, particularly under the higher-emission scenarios. A 2020s-era CMIP6 analysis found the northeast monsoon could weaken, reducing rainfall by up to 11% near Mersing in Johor by 2031–2050. Projections for Sarawak point the other way in places: at Limbang, annual rainfall could rise by about 10.5% by 2071–2100 under RCP4.5. Overall uncertainty is high, and an increase in rainfall is expected to be larger in Sabah and Sarawak than in Peninsular Malaysia, although there is generally large uncertainty around precipitation projections.\n\nExtreme rainfall has already changed. According to a UNFCCC adaptation information sheet, annual maximum rainfall intensity has risen by 17% for one-hour events and 29% for three-hour events. Earlier modelling for the country warned of a possible increase in inter-annual and intra-seasonal variability, with more hydrologic extremes and potential flood and water supply problems. Flooding and drought are therefore likely to coexist, with heavier downpours during wet periods and longer dry spells in others. Drought effects on rivers and reservoirs are discussed in the hazards section.\n\nSea-level rise and low-lying coasts\n\nUnder RCP pathways, sea levels could rise by approximately 0.4–0.7 m by 2100, with greater rises in Sabah and Sarawak. The exposure is considerable because much of the population and farmland lies on flat coastal and deltaic land. Urban areas, which hold around 70 percent of the population, including Malacca, Penang, Johor and Kuala Lumpur, already experience extreme storms with heavy rainfall. Higher seas also raise the baseline from which storm surges and river floods start. One study estimated that a 90 cm rise would destroy the country's mangroves entirely, while failure of coastal bunds could inundate about 1,000 km² of agricultural land. A separate estimate for a 1 m rise cited the loss of about 180,000 hectares of agricultural land, including paddy, rubber, coconut and oil palm, and a 15–20% loss of coastal mangrove forest.\n\nMangroves are both a casualty and a defence. Malaysia has already lost 15–20% of its mangrove forests along the coastline. Clearing for urban expansion and aquaculture has significantly degraded these ecosystems, reducing their protective function. Replanting is constrained because suitable areas for mangrove replanting are shrinking as sea levels rise, due to backshore development and existing land use. Modelling of revetment-protected and mangrove-buffered shores at Pantai Punggur found that hard structures delayed inundation more effectively in the early decades, but by 2100 their effectiveness diminishes over long-term sea-level rise scenarios, whereas mangrove ecosystems offer sustained, nature-based resilience. Sandy beaches are also affected. Beach nourishment is used at tourist beaches such as Port Dickson and Kuala Terengganu, but it requires periodic maintenance of sediment supply to remain effective as a soft engineering approach against erosion.\n\nMarine ecosystems and fisheries\n\nWarming seas pose a direct threat to coral reefs. Reefs in Peninsular Malaysia cover more than 4,000 km² and host over 500 hard coral species, and projections suggest severe heat stress could bring annual severe coral bleaching as early as 2035. The 2024 global bleaching event reached Malaysian waters, and more than 50% of coral reefs in several marine parks were affected by mass bleaching. Local research suggests thresholds are low: prolonged seawater temperatures above 27 °C, exceeded by as little as 1–2 °C, can induce bleaching and coral loss. Responses vary between sites. In Sabah, an average of 9.6% of colonies bleached on a shallow turbid reef, compared with 37.1% on a clear-water reef. Because reefs, mangroves and estuaries underpin fisheries and tourism, these environments provide coastal protection, carbon storage and livelihoods for local communities. Warming, acidification and extreme weather are therefore linked to declining marine biodiversity and fish stocks along the South China Sea coast.\n\nAdaptation measures\n\nBecause sea level cannot be lowered locally, adaptation strategies focus on reducing exposure and vulnerability. Proposed measures include coastal defences, beach nourishment, offshore barriers, flood gates and mangrove creation. Studies stress that these responses should be built into local policy, planning and resilience strategies. Hybrid designs that combine hard structures with mangrove conservation and restoration are increasingly favoured, because they can strengthen long-term shoreline stability and climate adaptation. Spatial planning also matters. Some analysts recommend coastal zone management plans that move communities further inland and onto higher ground. Economic assessments remain incomplete. An earlier study put the additional cost of sea-level rise in 2030 at about US$5.75 billion (PPP). Forest conservation in upland catchments, which regulates runoff into rivers and reservoirs, is treated as a complementary measure in the broader adaptation framework." }, { "heading": "Population distribution and urbanization", "text": "Malaysia's population is very unevenly spread. The densest settlement lies on the western side of Peninsular Malaysia, where the country's main axis of economic development runs through the tin and rubber belt. The major area of population concentration in Peninsular Malaysia is an axis of economic development on the west side of the peninsula. Smaller concentrations appear in the river deltas of Kelantan and Terengganu on the northeast coast, while most of the remainder of the peninsula, the interior uplands and most of the east, is sparsely populated.\n\nThe gap with East Malaysia is much wider. Using 2016 figures, the peninsula averaged about 95.7 persons per square kilometre, while Sarawak's 2020 population of 2,560,600 spread over roughly 124,450 km² works out to only about 21 per km². Some older compilations give densities for Sabah and Sarawak that are orders of magnitude lower, which appear to reflect unit errors, so census-based figures are more reliable. Sabah recorded a population of 3,418,785 in the state in the 2020 census, and its population is concentrated along coastal areas, with towns and urban centres seeing the most population growth. The state's density was about 46 per km² in 2020, and it hosted the highest number of non-citizens of any state, at 810,443.\n\nUrbanisation also differs sharply by region. 46% of the population in East Malaysia live widely scattered in the rural areas compared to 20% in Peninsular Malaysia and the national average of 29%. The low density of Sabah and Sarawak is closely tied to this rural share, and as on the peninsula, settlements are concentrated along the coasts and rivers.\n\nGrowth of the capital region and other cities\n\nKuala Lumpur began as a tin-mining settlement at the meeting of the Klang and Gombak rivers, and it has since grown into the core of a large metropolitan region. Its role as a administrative centre changed the city's trajectory. Klang had been the seat of colonial administration for Selangor from 1875, but the capital moved to Kuala Lumpur in 1880 as tin mining made the latter the more important centre. After Malaysian independence in 1957, Kuala Lumpur was the centre of the new government and it was free to promote the city's development as a matter of policy. The city's population rose from 977,102 in 1980 to 1,887,674 in 2007, and between 1960 and 2018 it doubled roughly every 13 years, a rate the source attributes largely to political decisions rather than market forces alone.\n\nThe metropolitan area has expanded far beyond the city boundary. The Klang Valley, which includes Kuala Lumpur, Putrajaya and parts of Selangor, had a population of 8,146,111 in 2020 over about 3,450 km². Growth was driven by industrialisation, the oil boom and higher-value services, and it was accompanied by the spread of housing and industry along corridors toward Port Klang, which had been developed from 1901 onward. Suburban growth has been fastest in the surrounding towns, as the city had consistently recorded net-out migration during the period, and the concentration of population has shifted from the city centre toward suburban areas since the 1980s.\n\nOther major urban centres also drew migrants. Major urban centres such as Kuala Lumpur, Georgetown, and Johor Bahru became the main destination for migrants seeking better economic and social opportunities. In Sabah, the Kota Kinabalu area is the largest urban concentration, with a population of 500,425 in 2020 in the Kota Kinabalu district, and the wider Greater Kota Kinabalu area of several districts has been planned as a single urban region.\n\nRural settlement patterns\n\nRural settlement follows access and terrain. Along the peninsula's coasts and river mouths, villages and towns cluster around fishing grounds, rice land and trade routes, while the mountainous interior remains thinly settled. In Sarawak, the density of people in the southwest makes this region the most important in East Malaysia. In Sabah, the population is similarly clustered on the coast, but riverine settlements are less important there than they are in Sarawak. Many Sarawakian Malays still live along the coast in kampungs, traditional village communities that have historically depended on the sea for their livelihood. The Iban, the largest group in Sarawak, are concentrated in the riverside longhouse communities of the interior and make up one-third of Sarawak's population.\n\nDemographic composition by region\n\nMalaysia's population has grown to about 34 million. According to the Department of Statistics Malaysia, Malaysia's total population was estimated at 34.2 million in 2025 and 34.4 million in the first quarter of 2026. Citizens make up most of this population, and among citizens the Malays are the largest group at about 58 per cent, followed by Chinese at about 22 per cent, Other Bumiputera at about 12 per cent and Indians at about 6.5 per cent. The term Bumiputera, meaning \"sons of the soil\", covers Malays together with the Indigenous peoples of the peninsula and Borneo; the combined Bumiputera share was about 70 per cent of citizens in 2025. Earlier estimates differ, with one source reporting 63.8% percent Bumiputera for 2023, which likely reflects different denominators and dates.\n\nThe regional composition is very different. On the peninsula, the Orang Asli are the Indigenous peoples, and Orang Asli actually refers to several distinct peoples who are native to the Malaysian Peninsula. The population of the peninsula's urban centres is mostly Chinese and Malay, with Indians and Pakistanis forming a small but salient minority. In Sabah, the three largest indigenous groups in Sabah are the Kadazan-Dusun, Bajau, and Murut. The Kadazan-Dusun are farmers, while the Bajau have a long association with the sea. In Sarawak, Indigenous groups include the Iban, Bidayuh and Orang Ulu. Within the Bumiputera category, DOSM splits the non-Malay groups by state: Sabah accounts for 55.3 per cent of the group and Sarawak for 32.3 per cent. Among non-Bumiputera residents in Sabah, citizens of Chinese descent make up the majority of the non-Bumiputera population." }, { "heading": "Economic geography and resource base", "text": "Malaysia's economic geography divides into two broad patterns: hydrocarbon extraction, concentrated in the offshore waters off Sarawak and Sabah, and manufacturing and transshipment trade, concentrated on the peninsula's western seaboard. Almost all of Malaysia's existing oil and gas fields are located offshore. Production is dominated by the state oil company Petronas, which runs extensive offshore infrastructure, pipelines and LNG facilities.\n\nPetroleum and natural gas\n\nSarawak has been the country's largest gas-producing state since 2005, and most of its output feeds liquefied natural gas (LNG) plants at Bintulu. A large portion of Malaysia's gas production is exported as LNG, particularly through the Bintulu LNG complex in Sarawak, one of the largest LNG export facilities in the world. In 2021, about 33.5 bcm of the 74.2 bcm of gas produced was shipped abroad as LNG, mainly to Japan, China and South Korea. Gas from fields off Peninsular Malaysia is used at home and for export, while gas from offshore Sabah and Sarawak serves domestic demand and LNG exports. The Kasawari field in the South China Sea, for instance, was designed to supply a ninth liquefaction train at the Bintulu complex, with an estimated resource of about 3.2 trillion cubic feet.\n\nCrude oil output has been falling. Petroleum and other liquids production declined between 2017 and 2023 to 597,000 barrels per day, due to maturing fields. The offshore sector's history reaches back to the 1960s, when Shell's West Lutong field became the first offshore field to produce oil in Malaysia. Projections now point toward a different balance: despite its position as a major exporter, Malaysia is expected to become a net gas importer within one to two decades as domestic supplies dwindle and local demand grows. The result is a tension between an export-oriented gas industry in the east and a domestic energy system that increasingly depends on new supply and on renewable energy and transition planning.\n\nElectronics and semiconductor clusters\n\nManufacturing is concentrated in a small number of states, and Penang is the most prominent. Penang's industrial base dates to the establishment of Malaysia's first free trade zone in 1970, and the state now hosts more than 350 firms, according to figures cited by its government. The state accounts for about 5% of global semiconductor exports, driven mainly by backend processes. The state's electrical and electronics exports were valued at about 34.1 billion ringgit in 2023, roughly 58% of Malaysia's total, and in the same year Penang drew about 47% of the country's manufacturing foreign direct investment. The emphasis lies on assembly, testing and packaging (OSAT) rather than on wafer fabrication, which is one reason the cluster is closely tied to global supply chains.\n\nJohor and the Klang Valley form the second and third parts of this pattern. Semiconductor production is spread across Penang, Johor and Selangor, while industrial electronics is clustered in Negeri Sembilan, Johor, Selangor, Kedah and Melaka, with the heaviest concentration in Penang and Kulim in Kedah. Johor hosts backend semiconductor plants and electronics manufacturing services, and its location next to Singapore makes it attractive for cross-border supply. The clusters depend on infrastructure that is under strain. Penang Island has limited land, and a 275 kV transmission project was built to deliver about 2,000 MW from the mainland, against an island peak demand of roughly 800 to 1,000 MW. Water demand also rose sharply between 2019 and 2023, coinciding with the semiconductor boom.\n\nPorts, transshipment and the Strait of Malacca\n\nMalaysia's container trade is organised around the Strait of Malacca, one of the busiest shipping lanes in the world. Port Klang, near Kuala Lumpur, is the largest and busiest port in the country. In 2025 it handled 15.14 million TEU, its highest total since 1973, and transshipment accounted for 8.41 million of that, about 55.5%. The Port of Tanjung Pelepas (PTP), at the mouth of the Pulai River in southwestern Johor, is a free-zone transshipment terminal close to the Strait's international lanes. Its containers are dominated by transshipment, with over 90% of its traffic moving between ships rather than entering the Malaysian economy. Across Singapore, PTP and Port Klang, an estimated 80% of containers are transshipped. Reported throughput figures for PTP differ across sources, partly because of the time period and the counting method used.\n\nThese ports mainly handle other countries' cargo, so their volumes say more about Malaysia's position as a hub than about its domestic trade. PTP is also linked to the peninsula's freight railway, which runs from Johor southward and northward toward southern Thailand, and to road networks. Competition is increasing, as Thailand and Vietnam expand their own container facilities. Malaysia's gains from this transit trade therefore depend on keeping costs and service levels competitive with Singapore and the regional ports.\n\nRegional differences in development\n\nThe economic divide between the peninsula and East Malaysia follows from these patterns. The western peninsula combines manufacturing, export-oriented electronics, port services and the largest urban labour markets, while Sabah and Sarawak rely more heavily on resource extraction, LNG exports and the revenues that flow from them. Because gas and oil output is capital-intensive and concentrated in a small number of large facilities, its revenue does not automatically translate into broad employment or local industrial development. This structural difference, rather than the resources themselves, shapes the gap in income and living standards between the regions, and it is the main reason that policy debates on resource revenue sharing and regional development recur in Malaysia." }, { "heading": "Transport and infrastructure networks", "text": "The North–South Expressway forms the backbone of the peninsula's road system. The tolled network runs along the west coast and totals about 772 km across two routes, passing through seven states and linking the Thai and Singapore borders. It was built because traffic congestion on Federal Route 1 had grown, and it was officially opened on 8 September 1994 and is operated by PLUS Expressways. The expressway is designated AH2 in the Asian Highway Network. Earlier, the peninsula's first long-distance dual carriageway, opened in 1967, linked Port Swettenham (now Port Klang) with Kuala Lumpur. A proposal for an east–west highway between Gerik in Perak and Jeli in Kelantan was championed by the first prime minister, Tunku Abdul Rahman. Cross-peninsula road links remain far less dense than the north–south corridor.\n\nRail development on the east coast is centred on the East Coast Rail Link (ECRL), a standard-gauge electrified line of about 665 km. The Malaysian unit of China Communications Construction is the contractor for the line. The project is part of China's Belt and Road Initiative. It was approved in 2016 but was put on hold in July 2018 because of domestic financial difficulties. The project was revived later with a significantly reduced scope and cost. The current budget is put at RM50.27 billion. By August 2026, overall progress had reached 95.08%, and the first phase, Kota Bharu to Gombak, was scheduled for completion in December 2026 with commercial operations targeted for January 2027. The second phase, from Gombak to Port Klang in Selangor, is expected to be completed by December 2027. A further 25 route-km branch, covering the western section known as Section D, will serve the ports at Northport and Westports, which will allow Malaysia's two largest container terminals to be rail-served. The transport minister has reportedly urged bringing the opening forward to the end of 2026. Some earlier planning documents quoted a length of about 640 km, so the figure of 665 km used in later reports reflects the expanded scope.\n\nWithin the Klang Valley, the conurbation around Kuala Lumpur relies on a multi-line urban rail system made up of commuter services, light rail, metro and monorail lines, which link the capital with the surrounding Selangor towns and Putrajaya.\n\nOn Borneo, road building has been far slower and has been shaped by the terrain and by the separation of the two states from the peninsula. The Pan Borneo Highway was first proposed when Sarawak and Sabah joined Malaya to form Malaysia in 1963. Before it was complete, the main through-route depended on existing sections, and the Lawas–Temburong stretch, linking Sarawak, Sabah and Brunei, was completed in 1997. This made it possible to drive from Kuching to Kota Kinabalu.\n\nThe Sarawak section has advanced further. As of 30 June 2026, the Sarawak Phase 1 project was 99.98% complete, with ten of its eleven work packages fully completed and opened to the public, and the remaining package scheduled for 2029. In Sabah, Phase 1 runs 706 km from Sindumin on the Sarawak border to Tawau, and Phase 1A was 87.86% complete as of July 2026. Delays have been attributed to land acquisition disputes and compensation and to the need to move power lines, water mains and telecoms within the road reserve. Parts of the Sabah highway still have dusty diversions and half-finished lanes.\n\nBecause many interior and coastal communities in Sabah and Sarawak are still poorly connected by road, air services and boats remain essential. Rivers such as the Rajang in Sarawak have long served as the principal routes into the interior, and small aircraft and coastal ferries carry passengers and goods to places not yet reached by highway." }, { "heading": "Territorial disputes and maritime boundaries", "text": "The Strait of Malacca gives Malaysia a stake in one of the world's busiest sea lanes. The waterway, which separates the Malay Peninsula from Sumatra, is about 1.5 nautical miles (2.8 km) wide at its narrowest point. Because it offers the shortest sea connection between the Indian and Pacific oceans, it makes the shortest shipping route between these two major bodies of water. Traffic estimates differ: one source counts over 50,000 ships passing each year, while another puts the combined traffic of the Malacca and adjacent Singapore Strait around 90,000 ships per year. Shares of world trade are reported in different ranges. A Center for Strategic and International Studies calculation cited by the Warsaw Institute holds that about 20% of global maritime trade and 60% of China's trade flows are moved through the Strait and the South China Sea. Energy flows are also heavy, with more than 70% of the PRC's petroleum and LNG exports reported to pass through the strait. The United States Navy lists it among the eleven critical choke points of global maritime shipping. Control of the waterway is shared by the littoral states, and Malaysia works with Indonesia and Singapore, three countries that are not always on the same political page.\n\nMalaysia's claims in the South China Sea rest mainly on its exclusive economic zone, which it says covers 334,671 km² under the UN Convention on the Law of the Sea, an area that overlaps with claims by China, the Philippines, Vietnam and Taiwan. Its UNCLOS-based claim is complicated by a continental shelf argument. Kuala Lumpur's continental shelf claim of 1979, followed in December of that year by publication of a map, drew protests from neighbours. Malaysia occupies five atolls in the Spratlys: Swallow Reef was occupied 1983; Mariveles Reef and Ardasier Reef in 1986; and Investigator Shoal and Erica Reef in 1999. Swallow Reef, or Pulau Layang-Layang, was seized in 1983 and established a military presence there. It has since reclaimed enough land to build an airfield and a small resort hotel on the atoll. Sources do not agree on how many features Malaysia claims: one describes at least 12 features in the Spratly Islands chain, a 2014 analysis counts seven islands or rocks in the Spratly group, and a later study describes ten atolls in the Spratly Islands near Sabah waters.\n\nThe legal position is contested. Malaysia's December 2019 submission to the CLCS pertained to its continental shelf claims in the northern part of the South China Sea, and it implicitly accepted a 2016 arbitral ruling that none of the Spratly features could generate an EEZ or continental shelf. An EEZ does not determine the ownership of the islands it surrounds. China's nine-dash line runs through Malaysia's Exclusive Economic Zone in the South China Sea and would reduce Malaysia's EEZ by 2/5th. Kuala Lumpur does not recognize China's nine-dash line claim, and it has relied on UNCLOS for sovereign rights to the natural resources in its EEZ. The economic stakes are substantial. Malaysia's offshore claims are estimated to hold five billion barrels of oil reserves and 80 trillion cubic feet of gas reserves, and the Royal Malaysian Navy has faced repeated incursions, with Chinese vessels entering the zone 89 times between 2016 and 2019 alone.\n\nThe dispute over Sabah dates to an agreement of 22 January 1878 between the Sultan of Sulu, Sultan Jamalul Alam, and representatives of the British North Borneo Company. The two sides read the document differently: while Malaysia and the British considered the 1878 contract signed with the Sulu Sultanate as a sale of land, the Philippines has argued that North Borneo/Sabah was on lease by the Sultanate of Sulu to the British. Manila formally asserted its claim in 1962, arguing that it had inherited the rights of the Sultanate of Sulu following the integration of Sulu into the Philippine state. When Malaysia was formally established on 16 September 1963, Sabah became one of its constituent states. Kuala Lumpur regards the question as settled, while the Philippines refused to formally relinquish its claim, maintaining that historical rights derived from the Sultanate of Sulu persisted. Official positions have shifted in tone. A 2022 statement from the Philippine presidency described the heirs' claim as \"in the nature of a private claim\" between two private parties. The dispute became violent in February 2013, when over 200 followers of the late self-proclaimed sultan of Sulu, Jamalul Kiram III, engaged Malaysian forces in a two-week battle to reclaim Sabah. A separate commercial arbitration brought by claimants to the Sulu heritage, worth about USD 14.9 billion, was later annulled.\n\nMalaysia also shares land boundaries with Thailand on the Malay Peninsula and with Indonesia and Brunei on Borneo." }, { "heading": "History of geographic knowledge and exploration", "text": "Classical and Indian Ocean knowledge\n\nGreek and Roman geographers called the peninsula the Golden Chersonese, a name that appears most famously in Claudius Ptolemy's 2nd-century Geography, the work that gave Ptolemy his lasting reputation as a geographer. Earlier writers had described a Golden Isle, and some in modern times have argued that this referred to Sumatra rather than the peninsula. Ptolemy's map replaced the older \"Golden Island\" label, which seems to have come from Indian reports about mines on Sumatra (Indian accounts of the mines on Sumatra). Ptolemy also recorded a local name, Maleu-kolon, a term thought to derive from Sanskrit. East of the peninsula, his map shows a large sea, the Great Gulf, which joined the Gulf of Thailand and the South China Sea (bound by the unknown lands thought to enclose the Indian Sea).\n\nKnowledge of the region moved through trade and scholarship. A voyage by a sailor named Alexander, whose route Marinus of Tyre used, is said to have reached the peninsula and sailed beyond it. An inscription on a South Indian temple records Malaiur, a kingdom on the peninsula described as having a strong mountain for its rampart. Ptolemy's text later passed into the Islamic world, where it was translated into Arabic by a team of scholars including al-Khwārizmī in the 9th century. Chinese and Arab navigators and merchants also recorded the peninsula's ports and products, and the medieval kingdoms of the Strait of Malacca area are reconstructed largely from such fragmentary sources. Paul Wheatley's study of the region attempts to reconstruct the historical geography of the Malay Peninsula from the beginning of our era to c. A.D. 1500.\n\nEuropean surveys and colonial boundaries\n\nEuropean mapping of the peninsula began with commercial expansion. In 1771 a trading firm based in Madras sent Francis Light to meet the Sultan of Kedah to open its market, and the first British settlement, at Penang, followed in 1786 (the first settlement was the Penang territory, in 1786). Malacca had been a Dutch possession since 14 January 1641 as the seat of the Dutch colony, and the Dutch did not relinquish it until the British and Dutch agreed terms.\n\nThe Anglo-Dutch Treaty of 1824 set the basic outline of the modern boundary. The Dutch colony of Malacca was ceded to the British in the Anglo-Dutch Treaty of 1824 in exchange for the British possession of Bencoolen and for British rights in Sumatra. The treaty created a notional line through the Singapore and Melaka straits that defined spheres of influence, and that line would later become part of the national border of Indonesia and Malaysia/Singapore. Borneo was less clear. The treaty text referred only to lands south of the Singapore Strait, so the position of the island was intensely debated in the 1840s and 1850s. The land boundary on Borneo was ultimately fixed through later agreements. The boundary, which measures approximately 1,107 miles in length, was delimited by Anglo–Dutch agreements negotiated during the preindependence period. Subsequent treaties in 1891; 1915; 1928 refined it, and only two small sectors have been demarcated on the ground. Surveys of this kind created the frontiers that Malaysia inherited at independence.\n\nNineteenth-century biogeography\n\nBetween 1854-1862, the naturalist Alfred Russel Wallace worked across the archipelago and, through his explorations of the Malay archipelago, discovered a major geographic discontinuity in animal distribution. He collected roughly 125,000 specimens during the expedition, and his findings were later published in The Malay Archipelago in 1869.\n\nThe boundary that now bears his name, the Wallace Line, runs through the Lombok Strait between Bali and Lombok, then north through the Makassar Strait between Borneo and Sulawesi. To the west, animals are largely of Asian origin, and in the east the fauna reflect Australasia. Borneo, including Sabah and Sarawak, therefore lies on the Asian side of the divide, which Wallace treated as evidence of a sharp break in the region's biota. The explanation given for the line is physical: the deep-water channels in the Lombok and Makassar straits were never bridged by land even at the lowest Pleistocene sea levels. Wallace's work is also a foundation of the discipline, and he is sometimes called the \"father of biogeography\". The exact placement of the line remains debated, because different taxonomic groups produce different line positions." } ], "links": [ "ocean", "mountain", "sea-level-rise", "estuary", "river", "drainage-basin", "wetland", "groundwater", "el-nino", "climate-change", "forest", "alfred-russel-wallace", "ptolemy" ], "sources": [ { "title": "Geography of Malaysia", "url": "https://en.wikipedia.org/wiki/Geography_of_Malaysia" }, { "title": "Peninsular Malaysia", "url": "https://en.wikipedia.org/wiki/Peninsular_Malaysia" }, { "title": "Malaysia", "url": "https://www.encyclopedia.com/places/asia/malaysia-and-singapore-political-geography/malaysia" }, { "title": "MALAYSIA", "url": "https://www.icid.org/i_d_malaysia.pdf" }, { "title": "Malaysia", "url": "https://en.wikipedia.org/wiki/Malaysia" }, { "title": "Malaysia", "url": "https://www.nationsencyclopedia.com/geography/Indonesia-to-Mongolia/Malaysia.html" }, { "title": "MARXIST: Geography of Malaysia", "url": "http://radhikaranjanmarxist.blogspot.com/2013/11/geography-of-malaysia.html" }, { "title": "Tanjung Piai", "url": "https://en.wikipedia.org/wiki/Tanjung_Piai" }, { "title": "Tanjung Piai - Johor National Parks", "url": "https://johornationalparks.gov.my/tanjung-piai/" }, { "title": "Malaysia's Geography and Landforms", "url": "https://www.scribd.com/document/613666955/dsd" }, { "title": "The States and Federal Territories of Malaysia", "url": "https://www.worldatlas.com/articles/the-states-and-federal-territories-of-malaysia.html" }, { "title": "Malaysia Maps & Facts - World Atlas", "url": "https://www.worldatlas.com/maps/malaysia" }, { "title": "East Malaysia", "url": "https://en.wikipedia.org/wiki/East_Malaysia" }, { "title": "States and Federal Territories of Malaysia", "url": "https://malaysiapostcode.com/states" }, { "title": "States and federal territories of Malaysia facts for kids", "url": "https://kids.kiddle.co/States_and_federal_territories_of_Malaysia" }, { "title": "Putrajaya", "url": "https://en.wikipedia.org/wiki/Putrajaya" }, { "title": "Putrajaya", "url": "https://www.britannica.com/place/Putrajaya" }, { "title": "Federal territories of Malaysia", "url": "https://en.wikipedia.org/wiki/Federal_territories_of_Malaysia" }, { "title": "What Is The Capital Of Malaysia?", "url": "https://www.worldatlas.com/articles/what-is-the-capital-of-malaysia.html" }, { "title": "Malaysia Agreement 1963 (MA63): Sabah's Constitutional Safeguards Explained", "url": "https://sabahguide.com/history/malaysia-agreement-1963/" }, { "title": "“Autonomy in Sarawak and Sabah: Different Paths and Diverging Outcomes” by Arnold Puyok", "url": "https://www.iseas.edu.sg/articles-commentaries/trends-in-southeast-asia/autonomy-in-sarawak-and-sabah-different-paths-and-diverging-outcomes-by-arnold-puyok/" }, { "title": "Landscape, Geology and Soils of the Malay Peninsula", "url": "https://msss.com.my/mjss/Full%20Text/vol27/V27_02.pdf" }, { "title": "Granite emplacement and tectonic subdivision of Peninsular Malaysia", "url": "https://gsm.org.my/articles/702001-101291/" }, { "title": "Advancing resistivity-chargeability modeling for complex subsurface characterization using machine learning and deep learning", "url": "https://arxiv.org/pdf/2509.17089" }, { "title": "geology of peninsular malaysia", "url": "https://gsm.org.my/wp-content/uploads/gsm_file_2/702001-101657-PDF.pdf" }, { "title": "(PDF) The Geology of Mount Kinabalu", "url": "https://www.researchgate.net/publication/244483683_The_Geology_of_Mount_Kinabalu" }, { "title": "Map of the Peninsular Malaysia shows the Western Belt granite in...", "url": "https://www.researchgate.net/figure/Map-of-the-Peninsular-Malaysia-shows-the-Western-Belt-granite-in-relation-to-other_fig5_239731592" }, { "title": "Sunda Shelf", "url": "https://en.wikipedia.org/wiki/Sunda_Shelf" }, { "title": "Sabah earthquake a 2015 shock for the nation", "url": "https://www.malaymail.com/news/malaysia/2015/12/24/sabah-earthquake-a-2015-shock-for-the-nation/1029201" }, { "title": "5.2-magnitude earthquake hits Ranau", "url": "https://www.themalaysianinsight.com/s/41889" }, { "title": "(PDF) The 2015 M w 6.0 Mt.
