As a child growing up in Nepal’s mountainous Upper Mustang region, Ghana Gurung understood that his survival depended on the mountains and his community. Today, as senior conservation program director at World Wildlife Fund-Nepal, he works to protect the endangered and elusive snow leopard by improving local communities’ livelihoods and the mountains’ ecosystem.

Climate change poses an undeniable threat to small island states, but many islanders do not even know what climate change is, says Camari Koto, an indigenous Fijian academic and educator at the University of the South Pacific and member of the Resilience Academy, in our latest podcast. “They know it’s happening, they are unconsciously [taking] adaptive responses,” and certainly feel the brunt of its effects, she says. “But they don’t see climate change as an immediate threat.”

“Innovation happens when there are pioneers that stick with it,” says Monica Kerrigan, vice president of innovations at Jhpiego in a podcast from the Wilson Center’s Maternal Health Initiative. At a recent panel discussion on “Reaching the Farthest Behind: Facility-Level Innovations in Maternal Health,” Kerrigan shone a light on some of the challenges facing innovators trying to change the way we care for mothers and their children.

Maps help us to grasp complex ideas, such as patterns of risk and vulnerability, but the stories they tell can have significant implications. “It’s very difficult to validate that what you’re capturing in the maps is representative of real-world phenomenon,” says Joshua Busby in this week’s “Backdraft” episode, describing his efforts to map climate and security hotspots in Africa and Asia. “You have to be modest in what you think the maps can tell policymakers, but also realize there is some seductive power in the way maps simplify complex reality.”

The Sahel region of Africa is a wide band that marks the transition from the Sahara Desert in the north to the wetter, sub-tropical regions in the south.

In recent years, insurgencies have surged in several countries, new terrorist groups have become active, there have been several droughts, and migration has increased.

Governments and health organizations have made remarkable gains in reducing maternal mortality and morbidity rates around the world. Much of those gains have been driven by increasing capacity, directing more women to hospitals and clinics to ensure they get modern medical care. Increasingly, however, experts are realizing that this push has brought challenges of its own.

As more and more development and humanitarian programs contend with climate-related problems, there are important lessons learned from past experience that should not be forgotten, says Janani Vivekananda, formerly of International Alert and now with adelphi, in this week’s episode of “Backdraft.”
