Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karimata Strait and the Java Sea. The Bukit Barisan mountains, which contain several active volcanoes, form the backbone of the island, while the northeastern area contains large plains and lowlands with swamps, mangrove forest and complex river systems. The equator crosses the island at its centre in West Sumatra and Riau provinces. The climate of the island is tropical, hot, and humid. Lush tropical rain forest once dominated the landscape.


Sumatra has a wide range of plant and animal species but has lost almost 50% of its tropical rainforest in the last 35 years. 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[edit]

Sumatra was known in ancient times by the Sanskrit names of Svarṇadvīpa ('Island of Gold') and Svarṇabhūmi ('Land of Gold'), because of the gold deposits in the island's highlands.[8] The earliest known mention of the current form "Sumatra" was in 1017, when the local king Haji Sumatrabhumi ("king of the land of Sumatra")[9] sent an envoy to China. Arab geographers referred to the island as Lamri (Lamuri, Lambri or Ramni) in the tenth through thirteenth centuries, in reference to a kingdom near modern-day Banda Aceh which was the first landfall for traders. The island has also been known by other names, including Andalas[10] or Percha Island.[11] Scholars suggest that mention of Suwarnadwipa in the Hindu Epic the Ramayana may be a reference to Sumatra. According to experts on The Ramayana, the epic is one of the first sources to document the relationship between India and the Indonesian archipelago[12]


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.[13][14]


From then on, subsequent European writers mostly used Sumatra or similar forms of the name for the entire island.[15][16]

Rail transport[edit]

Several unconnected railway networks built during Netherlands East Indies exist in Sumatra, such as the ones connecting Banda Aceh-Lhokseumawe-Besitang-Medan-Tebingtinggi-Pematang Siantar-Rantau Prapat in Northern Sumatra (the Banda Aceh-Besitang section was closed in 1971, but is currently being rebuilt).[48] Padang-Solok-Bukittinggi in West Sumatra, and Bandar Lampung-Palembang-Lahat-Lubuk Linggau in Southern Sumatra.
