The Chair gave a keynote address on 2 October at the conference in the Waterfront Hall in Belfast. The keynote was built around the quotation from American-Canadian author Jane Jacobs to illustrate the importance of participation and ownership: “Cities have the capability of providing something for everybody, only because, and only when, they are created by everybody”.
