There was a considerable trend of urban expansion onto hillsides from 2000 to 2020, which covered 11.65 million hectares globally. This expansion has destroyed 6.73 million hectares of natural habitats and further directly affected about 70% of threatened species, which highlights the fact that urgent policy action is needed to balance such development with terrestrial biodiversity conservation.
