Over the past century, orangutan populations in Southeast Asia have seen a very steep decline, driven to the brink of extinction by a host of man-made threats. Deforestation, illegal logging, the expansion of agro-industrial plantations and hunting - these forces combined to isolate orangutans into precarious pockets of forest on the islands of Borneo and Sumatra. Now, a new threat has emerged: climate change. This report assesses the impacts of land cover change and climate change on Borneo's endangered orangutans. It also examines the major driver of deforestation - the expansion of oil palm - and analyses how various land-use scenarios might impact the region through different climate change projections. As global initiatives are being set in place, it is encouraged to utilize these approaches to ensure a path towards sustainable development, not just for the benefit of humankind, but also for its closest relatives, the orangutans.
