The debate on “Kiezblocks” (similar to the concept of low-traffic neighbourhoods) in Berlin has so far been driven by civil society. Now, the engagement of more than fifty of them has got the new red-red-green government coalition in Berlin to anchor Kiezblocks in their coalition agreement. Even researchers and the public administration are starting to take the idea seriously. But how does an idea go from a demand to a democratically taken decision, and then to implementation? Are these processes a symbol of participative urban planning, or is their being taken up in the coalition agreement instead a top-down government programme? Does it even matter? In this blog post, we hope to shed some light on these questions.
