The context of liveable cities changes continuously. Cities need to be sustainable not only in their environmental, social, and economic aspects, but at the same time, they need to be equitable, healthy, and smart. ‘‘To which extent is urban planning today taking these concerns into account?’’ is the main question driving this book. Its focus is on equity and sustainability. It asks ‘‘How to engineer neighbourhood diversity and density?’’, ‘‘How to develop economies for specific places?’’, and ‘‘How to locate the social and economic opportunities?’’ On top of two introductory chapters, the book is structured in three parts of which the first one shows how planners reshape neighbourhoods for sustainable growth through changes in design, density, and diversity. The four chapters in this section are about planning for density, jobs, mixed income, neighbourhoods, and regional growth. Using well-selected examples from the San Francisco area in the USA, the section shows how planning will have to respond to dramatic recent and upcoming changes in population, its increasing diversity, and economy. The three chapters in the second part are about how a sustainable regional and local economy contributes to economic growth. The chapters show the need going beyond attracting the creative class to creating more liveable cities and investing in a green, smart economy. The three concluding chapters address poverty and opportunities. They point to the importance of incorporating public participation in the planning processes. The concluding chapter advocates regional planning. It stresses the importance of equitable and sustainable planning at the regional level. Over all, this is a most interesting book relating economy, poverty, demography, environment, and equity. It provides insight into how regional and urban planning for the next decades should look like. It uses cases from California (USA), provokes new ideas,
