Traveling Malaysia’s Pan Borneo Highway

Few infrastructure projects in Southeast Asia rival the scale — or stakes — of Malaysia’s Pan Borneo Highway. In 2019, Mongabay’s John Cannon traveled most of its length to document how one of Southeast Asia’s most ambitious infrastructure projects could potentially impact forests, wildlife and communities. This special series explores enduring questions the highway raised then and continues to raise now about habitat fragmentation, Indigenous land rights, and the ecological cost of connectivity. From field investigations to policy insights, the reporting offers a window into one of Borneo’s most transformative and controversial projects.
