Hindou Oumarou Ibrahim

Hindou Oumarou Ibrahim, from the Mbororo pastoralist community in Chad, has spent the past 10 years working to bridge the gap “between the international decisions [on climate change] with the reality on the ground,” she says. “I want to tell people what it is like in my country.”

Traveling the nation to meet with indigenous groups, she kept hearing how much the environment was changing. “Each year I am seeing resources shrinking, and my people are struggling for survival,” says Ibrahim. Leading up to the historic 2015 climate-change meetings in Paris, she was a key leader among indigenous groups that successfully lobbied to have their rights recognized, and she was selected to speak at the signing ceremony of the accords. Indigenous communities are among the most vulnerable to the impacts of climate change, but they can also offer solutions, says Ibrahim. “The traditional knowledge of indigenous people, that is centuries old, can help the world adapt.” —Jennifer Duggan
