The results of the study provides strong evidence that recognizing the rights of Indigenous Peoples to their traditional lands and waters is not only an ethical obligation it is essential to meeting local and global conservation goals. The authors say that more collaborative partnerships between Indigenous Peoples and governments would yield significant benefits for conservation of ecologically valuable landscapes, ecosystems, and genetic diversity for future generations.

"Understanding the extent of lands over which Indigenous Peoples retain traditional connection is critical for several conservation and climate agreements," said Professor Stephen Garnett from Charles Darwin University in Australia who led the international consortium that developed the maps. "Not until we pulled together the best available published information on Indigenous lands did we really appreciate the extraordinary scale of Indigenous Peoples' ongoing influence," he said.
