For this week’s Editor’s Picks, we’ve chosen four very different talks from four continents. The challenges they’re looking at may be familiar, but we like how the speakers bring new ideas and perspectives.
A new self-identity for Africans: Panashe Chigumadzi at TEDxJohannesburg
Panashe Chigumadzi is a young storyteller from Zimbabwe on a mission to redefine what it means to be African. Self-identity in many African countries has been skewed by the influence of colonization, she says, and in order to reclaim a sense of African identity, she urges people to use the power of new technology and social media to create positive cultural identities with uniquely African stories.

Is the war on drugs worth fighting? Maybe, says Bart de Koning, if we can look at it with new eyes. Despite concerted efforts, he explains, criminal justice systems haven’t stopped the supply and demand of illegal drugs. Instead, academic research has found that well-funded mental health facilities offer the only effective solution to what is ultimately a problem of addiction. In the war on drugs, this compelling call to action may offer a new way forward.
