Human-wildlife overlap is projected to increase across more than half of all lands around the globe by 2070.

We also found areas where human-wildlife overlap will decrease as human populations shift, although these were much rarer than areas of increase. We found that Africa will have the largest proportion of land with increasing human-wildlife overlap , followed by South America . In contrast, Europe will have the largest proportion of land experiencing decreasing human-wildlife overlap .Around the world, humans and wildlife increasingly compete for limited space on land.

The Marin Livestock and Wildlife Protection Program in California helps ranchers pay for nonlethal methods to protect their herds from coyotes.We developed a spatial index to measure human-wildlife overlap around the world. To calculate the degree of overlap region by region, we multiplied human population density by the number of species present in a given area. Our study included 22,374 land-dwelling species of amphibians, birds, mammals, and reptiles.
