Abstract
The overall aim of this paper is to show that managing healthcare in a crisis situation is both a strategic and frustrating exercise. First, we'll attempt to define a humanitarian crisis situation, bearing in mind that one crisis can conceal others. We're thinking here of the interface between territorial and sectoral crises. Secondly, we'll take a look at who manages health in crisis situations, with what instruments and with which actors. Finally, by drawing on concrete examples from two crisis situations of different origin and scope, in this case Niger in 2005 and Darfur at the same time, we intend to outline future challenges in the field of health management in humanitarian crisis situations.
