Projected Global Loss of Mammal Habitat Due to Land-Use and Climate Change

摘要: Summary Human pressure on the environment is driving a global decline of biodiversity. Anticipating whether this trend can be reverted under future scenarios key to supporting policy decisions. We used InSiGHTS framework model impacts land-use and climate change habitat availability for 2,827 terrestrial mammals at 15 arcmin resolution five contrasting based combinations representative concentration pathways shared socio-economic between 2015 2050. Mammal declined globally by 5%–16% depending scenario. Africa (with declines up 25%) South America were most affected regions. African insectivores, primates, Australian carnivorous marsupials marsupial moles, American opossums most. Tackling loss would require mix actions across scales, including shift toward sustainability, addressing in sub-Saharan Africa, helping endemic species track America.
