The mobilities framework offers a particularly informative and potent paradigm through which to draw together interdisciplinary scholarship about the present world. In this introduction—and indeed, derived from a symposia on mobilities in a dangerous world—we explore the dynamics of contemporary mobilities through a critical focus on “dangerous” spaces and places. We discuss the potential of a sustained dialogue between mobilities studies and our focus on risk, adversity, and perceptions of danger. Although disasters link to four of the articles, ideas are expanded to draw on the multiple scales of risk and danger in everyday life within and across an array of international contexts. In this special issue, dynamic mobilities are facilitated by ships, skate-boards, buildings, art, and cities; they are also encountered in darkness, in light, and through bodies as well as physical and imagined movements.
