Indonesia’s largest wholly owned island has lost half its rainforest
Sumatra covers about 482,287 square kilometres—the sixth-largest island on Earth and the biggest lying entirely inside Indonesia. In roughly thirty-five years it has lost almost half its tropical rainforest, pushing tiger, elephant, rhino, and orangutan toward critical endangerment. Its official area includes Nias, Simeulue and the Mentawai Islands.
The island stretches northwest–southeast between the Indian Ocean and the Strait of Malacca, with Simeulue, Nias, Mentawai, and Enggano offshore to the west. Sunda Strait and the Krakatoa archipelago separate it from Java; the equator crosses West Sumatra and Riau provinces through once-continuous rainforest. Sanskrit lore called it Svarṇadvīpa and Svarṇabhūmi—“Island/Land of Gold”—for highland deposits. The form “Sumatra” appears by 1017 with king Haji Sumatrabhumi; Arabs knew Ramni and Lamuri near modern Banda Aceh; Marco Polo wrote Samara while Odoric preferred Sumoltra.
Srivijaya, based in Palembang, dominated early medieval trade until Chola attacks around 1025 shrunk its reach. Islam entered via Arab and Tamil traders from the sixth and seventh centuries; Aceh later shipped premium pepper toward Mediterranean markets via the Red Sea. The Dutch fought the costly Aceh War from 1873 to 1903. Japan invaded in 1942. The Free Aceh Movement’s insurgency ran 1976–2005, with security crackdowns in 2001–02 killing several thousand civilians according to the sourced history. Krakatoa’s 1883 eruption and the 2004 Indian Ocean tsunami both hammered the coasts.
Scholars label the deforestation pattern an ecocide. What gold-seekers and pepper sultans once prized is now a frontline of habitat loss—still a continental-scale island cut by the equator, still shedding trees faster than legends of golden highlands can replace them. Adjacent islands from Nias to Bangka enlarge the cultural world even when maps draw one elongated main mass. Gold, pepper, and now palm oil have each taken turns rewriting the same equatorial slopes.
