Human trafficking is a form of serious exploitation and abuse that is increasingly present in the UN peacekeeping environments. Trafficking exploits human beings for revenue through sex, forced labour and human organs. For peacekeeping (UN and other) there is a crisis of perception in relation to trafficking and the linked issue of sexual exploitation and abuse, which sees peacekeepers branded as more part of the problem than the solution, along with criticisms that the issue is not taken seriously by peacekeeping institutions. Allegations and incidences of peacekeeper involvement with trafficking run counter to UN principles. Such incidents can be extremely damaging to missions by undermining implementation of police reform and rule of law mandates, perpetuating linkages to organized crime and providing material for anti-UN elements, obstructionists and negative media campaigns.
