Exploring the catalytic power of temporary urbanism through a binary approach

The routledge handbook of catalysts for a sustainable circular economy

“…Synchronisation is the precondition of the opening of a new phase in system development, transition state, in which several possible sustainability paths become available. The examination of these choices and probabilities of their realisation is important for the future development of urban regeneration, as we have done elsewhere (Engez et al, 2021b;Turku et al, 2022Turku et al, , 2023. Stepwise catalytic pathways refer to events and situations in which catalyst-specific mechanisms function in ways that overcome the energy barriers of the system and thus promote the systemic change (Table 2.3).…”

“…Recent work on policy design and policy processes (Capano & Howlett, 2021) demonstrates how policy catalysts ('activators' in their terminology) trigger first-and secondorder mechanisms in the studied system. Temporal issues, such as timing, sequence, and duration become important in these processes (Turku et al, 2022(Turku et al, , 2023.…”

“…While we particularly analysed technology-driven experiments for urban development following CE principles in Hiedanranta, we also considered the citizens, as they participated in many of these experiments (Engez et al, 2021a;Turku et al, 2022Turku et al, , 2023. Moreover, citizens were the primary actors in many other innovative projects in the area, focusing on the reuse of industrial spaces, new consumer cultures like do-it-yourself activities, and ideas for urban planning, including a new superblock implementable in the Hiedanranta area (Laine et al, 2017;Leino & Puumala, 2021;Sjöblom et al, 2021).…”

“…The analogy between chemistry and sustainability transition is based on dynamic similarities and applies despite the difference that a transition state in chemistry is instantaneous and very short, whereas in Hiedanranta, the transition state will take years, and possibly remains still partly open-ended. Its emergence is important for the next processes because it uncovers the potential for multiple sustainability paths (Turku et al, 2022(Turku et al, , 2023.…”
