This book is the final result of the COST Action ‘Public Value Capture of Increasing Property Values’ (PuVaCa, https://puvaca.eu/). The first idea for the COST Action, which led to the preparation of this book, was born in 2014 as a result of a presentation at an EALD congress (European Academy of Land Use and Development). The official start was in August 2018. The network of proposers was quite small. It included 9 scientists from 7 countries. Over the past three and a half years, the network has grown considerably. It now comprises more than 100 scientists from 41 countries, including many members of the PLPR (International Academic Association on Planning, Law and Property Rights). Because of the close links between this COST Action and the two organisations EALD and PLPR, their two presidents give themselves the honour of the Preface.
