For the first time in history, half of the world's population lives in urban areas and it is expected that, by 2050, that figure will rise to above two-thirds. A large proportion of this urban growth will be taking place in the cities of the developing world, where the provision of adequate health, shelter, water and sanitation and climate change adaptation efforts for rapidly-growing urban populations will be an urgent priority. This transition to an urban world could be a negative transformation; but, if well-planned, it could also offer an unprecedented opportunity to improve the lives of some of the world's poorest people.
This volume brings together some of the world's foremost experts in urban development with the aim of approaching these issues as an opportunity for real positive change. The chapters focus on three strategically critical aspects of this transformation:

• public health
• shelter, water and sanitation
• climate change adaptation.

These are considered using an integrated approach that takes account of the many different sectors and stakeholders involved, and always in terms of the solutions rather than the problems. The book offers a blueprint for action in these sectors and will be of great interest to academics and policymakers in all aspects of urban development and planning.
