Sumatra
Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The
Sumatra has a wide range of plant and animal species but has lost almost 50% of its tropical rainforest in the last 35 years.[clarification needed] Many species are now critically endangered, such as the Sumatran ground cuckoo, the Sumatran tiger, the Sumatran elephant, the Sumatran rhinoceros, and the Sumatran orangutan. Deforestation on the island has also resulted in serious seasonal smoke haze over neighbouring countries, such as the 2013 Southeast Asian haze which caused considerable tensions between Indonesia and affected countries Malaysia and Singapore.[2] The widespread deforestation and other environmental destruction in Sumatra and other parts of Indonesia has often been described by academics as an ecocide.[3][4][5][6][7]
Etymology

Sumatra was known in ancient times by the
In the late 13th century, Marco Polo referred to the kingdom as Samara, while his contemporary fellow Italian traveller Odoric of Pordenone used the form Sumoltra. Later in the 14th century the local form "Sumatra" became popular abroad due to the rising power of the kingdom of Samudera Pasai and the subsequent Sultanate of Aceh.[14][15]
From then on, subsequent European writers mostly used Sumatra or similar forms of the name for the entire island.[16][17]

The Free Aceh Movement fought against Indonesian government forces in the Aceh Insurgency from 1976 to 2005.[27] Security crackdowns in 2001 and 2002 resulted in several thousand civilian deaths.[28]
The island was heavily impacted by both the 1883 Krakatoa eruption and the 2004 Boxing Day Tsunami.

Sumatra's population as of 2023 was estimated to be about 60,795,669 ;[31] it has about the same number of inhabitants as South Africa, making it the fifth-most populous island in the world. Yet because it is such a large island, it is not densely populated: it has an average of about 126 people per km2.[32]
Ethnic groups
The largest indigenous ethnic groups in Sumatra are Malays, Minangkabaus, Bataks, Acehnese, and Lampungs. Other major non-indigenous ethnic groups are

Administration
Sumatra is one of seven geographical regions of Indonesia, which includes its adjacent smaller islands. Sumatra was one of the eight original provinces of Indonesia between 1945 and 1948. Including adjacent archipelagoes normally included with Sumatra (such as the Riau Islands, Nias and the Bangka-Belitung group), it now covers ten of Indonesia's 38 provinces, which are set out below with their areas and populations.[38]

Geography


The longest axis of the island runs approximately 1,790 km (1,110 mi) northwest–southeast, crossing the equator near the centre. At its widest point, the island spans 435 km (270 mi). The interior of the island is dominated by two geographical regions: the Barisan Mountains in the west and swampy plains in the east. Sumatra is the closest Indonesian island to mainland Asia.
To the southeast is Java, separated by the Sunda Strait. To the north is the Malay Peninsula (located on the Asian mainland), separated by the Strait of Malacca. To the east is Borneo, across the Karimata Strait. West of the island is the Indian Ocean.

Sumatra is a highly seismic island. Huge earthquakes have been recorded throughout history. In 1797, an 8.9 earthquake shook Western Sumatra, and in 1833, a 9.2 earthquake shook Bengkulu and Western Sumatra. Both events caused large tsunamis. Earthquakes are very common throughout the coastal area of the west and center of the island, and tsunamis are common due to the high seismicity in the area.[42][43]

By population, Medan is the largest city in Sumatra.[44] Medan is also the most visited and developed city in Sumatra.

Flora and fauna


Sumatra supports a wide range of vegetation types that are home to a rich variety of species, including 17 endemic genera of plants.
The island is home to 201 mammal species and 580 bird species. There are nine endemic mammal species on mainland Sumatra and 14 more endemic to the nearby
The Sumatran tiger, Sumatran rhinoceros, Sumatran elephant, Sumatran ground cuckoo, Sumatran orangutan and Tapanuli orangutan are all critically endangered, indicating the highest level of threat to their survival. In October 2008, the Indonesian government announced a plan to protect Sumatra's remaining forests.[48]
The island includes more than 10 national parks, including three which are listed as the Tropical Rainforest Heritage of Sumatra World Heritage Site – Gunung Leuser National Park, Kerinci Seblat National Park and Bukit Barisan Selatan National Park. The Berbak National Park is one of three national parks in Indonesia listed as a wetland of international importance under the Ramsar Convention.
Sumatra has lost almost 50% of its tropical rainforest since 1980. Many species are now critically endangered, such as the Sumatran ground cuckoo, the Sumatran tiger, the Sumatran elephant, the Sumatran rhinoceros, and the Sumatran orangutan. Deforestation on the island has also resulted in serious seasonal smoke haze over neighbouring countries, such as the 2013 Southeast Asian haze which caused considerable tensions between Indonesia and affected countries Malaysia and Singapore.[2] The widespread deforestation and other environmental destruction in Sumatra and other parts of Indonesia has often been described by academics as an ecocide.[3][4][5][6]
