In the 4th edition of the leading introductory textbook, Allmendinger provides a wide-ranging and up-to-date analysis of planning theories and how these relate to practice. Moving away from a linear, chronological model of progress over time from one paradigm to another, Allmendinger explains how and why different theories have gained dominance in particular places at particular times, providing a holistic view of the field.

The Covid-19 pandemic and the influence of digital technology - especially AI and machine learning - have led to speculation that the field is approaching the 'end of theory', and new frameworks for thinking about cities and planning. This revised edition analyses the position of established Marxist, neoliberal, postmodern and post-structural frameworks for planning, as well as considering collaborative practice, pragmatism, and new directions for the field. Chapters assume no prior knowledge of the topics covered, and consider the relationship between planning and the most pressing societal challenges, including climate change, sustainability, and health.

New to this edition:
- Comprehensively revised and updated throughout
- New chapters dedicated to 'Gender, Race and Diversity in Planning' and 'Planning and Theory in the Digital Age'

Allmendinger's unique approach to planning theory makes this an essential textbook for all undergraduate and postgraduate students of urban and environmental planning.
