After Fukushima: reflections on riks and institutional learining in an era mega-crises.

Triggered by the recent inquiries into the Fukushima nuclear disaster, this article reflects on the challenges of developing and operating risk regulation and crisis management regimes in an era of highly complex and tightly interconnected socio‐technical systems. These challenges are not just technical and professional but fundamentally institutional and cultural. The article identifies three key paradoxes and challenges of contemporary risk and crisis management, signals a range of recurrent problems in governments' efforts to cope with these challenges, problematizes current patterns of societal learning from crises, and sketches an agenda for public administration research in this area.
