When you think of all the conflicts we have - whether those conflicts are local, whether they are regional or global - these conflicts are often over the management, the distribution of resources.

I stand before you and the world humbled by this recognition and uplifted by the honour of being the 2004 Nobel Peace Laureate. As the first African woman to receive this prize, I accept it on behalf of the people of Kenya and Africa, and indeed the world. I am especially mindful of women and the girl child. I hope it will encourage them to raise their voices and take more space for leadership.

I would like to call on young people to commit themselves to activities that contribute toward achieving their long-term dreams. They have the energy and creativity to shape a sustainable future.
