The island of New Guinea hosts the third largest expanse of tropical rainforest on the planet. Papua New Guinea—comprising the eastern half of the island—plans to nearly double its national road network (from 8,700 to 15,000 km) over the next three years, to spur economic growth. We assessed these plans using fine-scale biophysical and environmental data. We identified numerous environmental and socioeconomic risks associated with these projects, including the dissection of 54 critical biodiversity habitats and diminished forest connectivity across large expanses of the island.

An unprecedented increase in oil palm developments may be underway in Papua New Guinea (PNG) through controversial ‘Special Agricultural and Business Leases’ (SABLs) covering over two million ha. Oil palm development can create societal benefits, but doubt has been raised about whether the SABL developers intend establishing plantations. Here we examine the development objectives of these proposals through an assessment of their land suitability, developer experience and capacity, and socio-legal constraints.
