In this hugely influential book, originally published in 2001 but just as - if not more - relevant today, Mark Duffield shows how war has become an integral component of development discourse. Aid agencies have become increasingly involved in humanitarian assistance, conflict resolution and the social reconstruction of war-torn societies. Duffield explores the consequences of this growing merger of development and security, unravelling the nature of the new wars and the response of the international community, in particular the new systems of global governance that are emerging as a result. An essential work for anyone studying, interested in, or working in development or international security.
