This book pays homage to Neil Smith's ideas, offering a critical approach and rich collection of insights that draw on Smith's work for inspiration and debate. With interdisciplinary and international contributions from leading experts, the book demonstrates the impact of Smith's ideas on understanding the role of urbanisation in general and gentrification, in particular, in contemporary society. The book demonstrates how gentrification varies significantly from city to city, across different cultural and political-economic regimes, and in terms of the timing of urban transformations. This collection provides a forum for debate for those working in urban regeneration and citizenship, and those directly affected by the processes and problems arising from gentrification. It will be of interest to students and scholars in urban geography, urban sociology, cultural studies, and wider social and urban theories.
