Director for Global Foresight & Innovation, Chris Luebkeman, was interviewed by Stephen Lacey, a producer with RenewableEnergyWorld. He was one of three asked to address the future of cities, energy supply and carbon reductions in the face of environmental and social challenges. His is the third interview.

Susan Thomas looks at where urbanisation is taking place, as well as some of its causes – from population growth through to the reclassification of rural areas. She also addresses the pros and cons of the process; the issues being faced in both developed and developing nations; megacities and eco-cities; and the ways in which designers are planning for the future.
