[From the introduction] This volume is a special issue with contributions that stem from the collaborations of the 2018 AESOP PhD workshop, held 5-8 July at Tjärö island, Sweden. The overarching aim of the workshop was to establish inclusive spaces for dialogue and collaboration between PhD students across countries and continents on issues that pertained to the AESOP’s 2018 congress theme “Making space for hope”. Furthermore the PhD students got the chance to learn from the invited mentors with long experience from the academic planning field. The theme drew from a recognition of the severe challenges facing the world at present, for example, challenges coupled with the climate crisis, growing social inequalities, rapid population growth in urban regions and de-population trends in peripheral regions.
