Conflict at both intergroup and interpersonal levels is a dominant theme of the human condition in the twenty-first century. Numerous violent international conflicts persist around the world. At the domestic level, tensions and conflicts also extend along divisions based on religion, race, ethnicity, social class, culture, and language. Moreover given the increasing strain on the world's environment, conflict over limited resources such as water, is likely to increase. Against this backdrop, conflict resolution emerges as a critical tool to address the causes of conflicts and build new and lasting relationships between hostile groups.
