Geoff was invited to provide some comments at the Norwegian Urban Conference following the showing of a film about the barriadas of Lima, made in the 1960s by John F C Turner and a follow-up film made recently by Professor Kathrin Golda-Pongratz. Geoff offered some comments on the impact that John Turner’s ideas have had on attitudes and policies of urban planning and housing.
