Gil Penalosa: liveable cities

Kim Hill talks to Gil Penalosa, renowned internationally for his work transforming Bogota, Colombia, by developing public spaces and enabling effective transit. He runs 8-80 Cities, a non-profit organisation based on the idea that a city built for an eight-year-old and an 80-year-old will be good for everyone. He visited New Zealand this week for the biennial 2Walk&Cycle conference.
