The video 'Fog Catcher' is (edited) from episode four of an eight-episode series Hot Cities which aired on BBC World in winter 2009. The series shows the differential effects of climate change in major cities in the world. In other words climate change impacts manifest in different ways … as a public health problem in Jakarta and as a water shortage in Lima. Of course the series also provides examples of 'innovation in context' and why innovation is not just about counting patents, R&D expenditures and personnel.
