The central theme of the 2011 WorldDevelopment Report (WDR) is that violent conflict remains aconstant threat to human rights, peace and sustainabledevelopment. While the nature of violent conflict maybechanging1 its negative impact on poor people in terms ofrights violations, public health, forced displacement anddiminution of life chances is the same. Critical toestablishing peace and the necessary confidence betweenstate and citizen is providing a sense of security, freedomfrom fear, and the protection of basic rights andentitlements. The purpose of this paper is to analyze therelationship, overlapping and sometimes contradictory,between a range of approaches to security and justice inconflict affected contexts, and to place these effortswithin a broader rule of law framework. This, it will beargued, greatly assists in addressing the kind of frictionsand blind-spots that commonly exist in making the transitionfrom violence to peace. The paper will then examine some ofthe instruments and approaches adopted by governments andinternational partners in addressing the kinds of stresseswhich result in violent conflict. Finally, it will examinethe gaps in the international arena which continue topersist in this area of support. A series of security andjustice-themed papers produced for the WDR 2011 outline inmore detail the issues, approaches and lessons of the keycomponents including: security, public security inpeacekeeping settings, criminal justice, justice andadministrative law, and transitional justice.
