A new study published in the journal Diversity and Distributions predicts massive range declines of Africa’s great apes — gorillas, chimpanzees and bonobos — due to the impacts of climate change, land-use changes and human population growth.

For their analysis, the authors compiled information on African ape occurrence held in the IUCN SSC A.P.E.S. database, a repository that includes a remarkable amount of information on population status, threats and conservation for several hundred sites, collected over 20 years.

The first-of-its-kind study quantifies the joint effects of climate, land-use, and human population changes across African ape ranges for the year 2050 under best- and worst-case scenarios. “Best case” implies slowly declining carbon emissions and that appropriate mitigation measures will be put in place. “Worst case” assumes that emissions continue to increase…
