Abstract of the article "Préventions des déplacements forcés de population – possibilités et limites" Since the end of the Cold War, the prevention of forced displacement has become a key topic of humanitarian agencies and international political bodies. Though alluring as a human and political solution, it still lacks adequate theoretical analysis. The article examines the challenges and hazards entailed by the emergence of this new concept, which appears to be both multidimensional in its objective and application and controversial in terms of its potential impact on certain norms and principles of international law. For all its many possibilities, the prevention of forced displacement is also a risky concept whose limitations should induce humanitarian operators to handle it with great care and restraint.
