Deforestation in Borneo has taken place on an industrial scale since the 1960s. Borneo, the third largest island in the world, divided between Indonesia, Malaysia and Brunei, was once covered by dense tropical and subtropical rainforests.
In the 1980s and 1990s, the forests of Borneo were levelled at a rate unprecedented in human history, burned, logged and cleared, and commonly replaced with agriculture. The deforestation continued through the 2000s at a slower pace, alongside the expansion of palm oil plantations. Half of the annual global tropical timber procurement is from Borneo. Palm oil plantations are rapidly encroaching on the last remnants of primary rainforest. Much of the forest clearance is illegal.
The World Wildlife Fund divides Borneo into a number of distinct ecoregions including the Borneo lowland rain forests which cover most of the island, with an area of 427,500 square kilometres (165,100 sq mi), the Borneo peat swamp forests, the Kerangas or Sundaland heath forests, the Southwest Borneo freshwater swamp forests, and the Sunda Shelf mangroves. The Borneo mountain rainforests lie in the central highlands of the island, above the 1,000 metres (3,300 ft) elevation. These areas represent habitat for many endangered species; for example, orangutans, elephants and rare endemics such as the elusive Hose's civet. The Bornean orangutan has been a critically endangered species since 2016.
As well as Borneo's importance in biodiversity conservation and as a carbon sink, the forests have significance for water security and food sovereignty for local communities of indigenous peoples.[1]
