Cities will play an increasing role in the welfare of both people and the environment in the future. How can we make them greener?
For the first time in history half of the world’s population is located in urban spaces rather than rural areas. By 2030, nearly 60% are expected to be urban dwellers.
Cities will be the powerhouse for future development and growth, and planning their future will make or break a green economy. Green cities will have to effectively and efficiently manage energy, recycle resources and make use of waste.
How can the historic human infrastructure of cities be transformed from grey to green by learning from the lessons of nature? How will they provide for the health and wellbeing of people, as well as the environment?
A panel of leading experts chaired by Richard Black, the BBC's environment correspondent, discussed the issues at a live debate at the Natural History Museum on 14 March 2012.
