CONTEXT: This section of the journal encourages discussion between several authors on a policy related topic. The same question may, therefore, be addressed from different theoretical, cultural or spatial perspectives. Dialogues may be applied or highly abstract. This Dialogue starts with Hylton and Long's original paper doi.org/10.1080/19407963.2015.1115950 and ends with Jacco van Sterkenburg's reflections below, prompted by the observations of fellow contributors.
