Lees is the lead author on Planetary Gentrification (248 pages). This output draws on the authors’ extensive research in different locations around the world over two decades. It makes an original contribution by questioning the Western-centric assumptions of gentrification studies and theorizing ‘planetary gentrification’. The in-depth exploration of multi-faceted aspects of gentrification globally necessitated a long-form presentation of the argument and supporting evidence. Through a series of consecutive chapters, the book builds a detailed argument about the role of the state as a driver of gentrification (as a form of regulation and securitization of urban territory).
