In June 2007, TED held its first conference in Africa, titled "Africa: The Next Chapter." Thought leaders from across the continent gathered with counterparts from around the globe to build new and lasting collaborations. Talks from TEDGlobal will appear here over the coming year, as part of the vigorous conversation unfolding worldwide, starting with Ngozi Okonjo-Iweala, George Ayittey, Euvin Naidoo, and William Kamkwamba. Earlier TEDs seeded this conversation: Ngozi Okonjo-Iweala, the pioneering Nigerian Finance Minister, offers a broader take on trade versus aid, while Jacqueline Novogratz promotes a new way of giving, based on investment. Ashraf Ghani, former Finance Minister of Afghanistan, gives a rousing talk that points the way forward out of the wreckage of a failed state. And Iqbal Quadir talks about the emerging economy where cellphones are both infrastructure and currency. And then there's Bono, whose memorable 2005 TED Prize acceptance speech was the inspiration for TEDGlobal2007.
