TANZANIA—This August, Arusha, Tanzania will be the hub for new ideas worth spreading for the TEDGlobal 2017 Conference. On the cusp of the highly anticipated event, TED just announced the 21 young innovators from around the world who will deliver a talk on the famous TED stage. Among the 21, 10 fellows are representing Uganda, Egypt, the Democratic Republic of the Congo, Nigeria, Somalia, Botswana, Zimbabwe, Liberia and Kenya.

TED returns to Arusha after hosting the 2007 TEDGlobal Conference, where the organization gathered 100 of the sharpest young leaders to meet in person for the first time. This group was a precursor to the Fellows program, including OkayAfrica 100 Women honoree Juliana Rotich, Patrick Awuah, Erik Hersman, William Kamkwamba and Fred Swaniker.

Since 2009, the program has presented talks from over 400 Fellows from 94 countries, whose talks have collectively been viewed more than 155 million times. The program continues to create a powerful, far-reaching network of scientists, doctors, activists, artists, photographers, filmmakers, entrepreneurs, inventors, journalists and more.

Meet the 10 African TED Fellows below, who will be joining leading policymakers, business people, academics and activists from across the continent and around the world. Be sure to check back at OkayAfrica for more leading up to TEDGlobal 2017.
