Peace and conflict studies
Peace and conflict studies is a field of social science that identifies and analyses violent and nonviolent behaviours as well as the structural mechanisms attending conflicts (including social conflicts), to understand those processes which lead to a more desirable human condition. A variation on this, peace studies, is an interdisciplinary effort aiming at the prevention, de-escalation, and solution of conflicts by peaceful means, based on achieving conflict resolution and dispute resolution at the international and domestic levels based on positive sum, rather than negative sum, solutions.
