Scale is an overlooked issue in the research on interactive governance. This book takes up the important task of investigating the scalar dimensions of collaborative governance in networks, partnerships, and other interactive arenas and explores the challenges of operating at a single scale, across or at multiple scales and of moving between scales. First published as a special issue of Policy & Politics, the volume explores the role of scale and scaling in a wide range of policy areas, including employment policy, water management, transportation planning, public health, university governance, artistic markets, child welfare and humanitarian relief. Cases are drawn from Asia, Australia, Europe, and North and South America and span all levels from local to global. Together, the theoretical framework and the empirical case studies sensitize us to the tensions that arise between scales of governance and to the challenges of shifting from one scale of governance to another.
