Unarmed civilian peacekeeping or protection (UCP) is a generic term that gives recognition to a wide range of activities by unarmed civilians to reduce violence and protect civilians in situations of violent conflict. There are many non-governmental as well as governmental organisations that engage in UCP, using a variety of methods and approaches. This study examines UCP in four conflict-affected regions: Colombia, Mindanao (Philippines), Palestine/Israel, and South Sudan. It focuses on what is emerging as good practice in these varied contexts and whether any commonalities can inform the expanded use of UCP.
