At the age of 22, Stephen Machua joined the organizing committee for the first-ever African Youth Charter Summit in Dar es Salaam, Tanzania. The committee comprised of young leaders from different regions in Africa.
Most of the summit preparations took place virtually but Stephen was tasked to travel a week before to facilitate final event preparations. He took up the challenge despite being unfamiliar with the city of Dar es Salaam.
The summit brought together 45 delegates from 14 African countries and Africans in the diaspora. The summit formed the foundation for continental-wide and country-specific dialogues on the need for the ratification of the African Youth Charter.
In Kenya, Stephen, through his organization (Change Mind Change Future) convened monthly dialogues on the African Youth Charter post-summit.
The conversations pressured the Kenyan Government to ratify the Charter and deposit the instruments of ratification at the African Union Heads of States summit in January 2014.
