This issue of Transactions of AESOP brings together papers that address key contemporary planning themes and agendas with a particular emphasis on appreciating the importance of time and space in shaping the substantive matters planning addresses and the manner in which it responds to these.
Collectively the papers provide a timely reminder that planning as an activity has both a temporal and spatial dimension. It is enmeshed in temporal and spatial processes with material effects and must be cognisant of different temporal and spatial scales as it seeks to shape territories which maximise human flourishing within safe environmental limits. We would like to thank all the authors and reviewers who have contributed to this issue of the Journal.
