This book analyses the making of the international world of 'natural' disasters by its professionals. Through a long-term ethnographic study of this arena, the author unveils the various elements that are necessary for the construction of an international world: a collective narrative, a shared language, and standardized practices. The book analyses the two main framings that these professionals use to situate themselves with regards to a disaster: preparedness and resilience, arguing that the making of the world of 'natural' disasters reveals how heterogeneous, conflicting, and sometimes competing elements are put together.
