The rapid increase in human population, industrialization, and climate change put the biological diversity of the planet at risk. In the race against time, we need to identify and protect those who guard this diversity. A recent study found that lands managed by indigenous communities have the highest rates of diversity.
How Do We Know?
Researchers focused on locating the highest biodiversity indexes in three of the largest countries in different latitudes: Australia, Brazil, and Canada. After quantifying the number of species of birds, mammals, amphibians, and reptiles, the researchers found that diversity was significantly higher in areas managed or co-managed by indigenous communities, regardless of the size of the area or its geographic location. National parks scored second on the list, followed by several sites without any protection.
