As human tragedies—such as armed conflicts, humanitarian crises, crimes against humanity, and genocide—continue to occur, early warning and conflict prevention are essential comprehensive subjects in any crisis and conflict prevention architecture. Early warning refers to the collection and analysis of information about potential crisis and conflict situations for the purpose of preventing the onset and escalation of such situations, preferably through appropriate preventive response options. Indeed, qualitative approaches to early warning and prevention have produced an impressive list of preventive mechanisms and tools, ranging from non-military—such as political and economic inducements, fact-finding, dialogue, and negotiations—to military ones, such as preventive missions. Meanwhile, a more theoretical and empirically guided approach has made extensive use of quantitative methods to create data-based predictive models for assessing risks of complex humanitarian crises, political instability and state failure, intrastate and ethnopolitical conflicts, and genocide and politicide, as well as other massive human rights violations. There are three types of analysis of risk assessment: the first makes use of structural indicators, the second of sequential models, and the third of inductive methods. However, there are challenges in early warning and conflict prevention posed by the warning-response gap and the issue of “missed opportunities” to prevent. At present, there is no U.N.-wide coordinated early warning system. Nevertheless, several efforts in establishing operational early warning systems on the level of regional and subregional organizations can be identified.
