Presentation Transcript

Someone somewhere has found a solution’

The PACE project was started to help organisations in one part of Africa get the benefits from the ideas and experiences of people working in other parts. By sharing ideas we don’t have to start from zero, we can learn from other people’s experiences and share our own findings with them, so everyone benefits.

The film we’re watching today has been shared with people in 22 countries.
