Nearly every UN and independent evaluation has found the collaborative approach deficient when it comes to IDPs. To begin with, there is no real focus of responsibility in the field for assisting and protecting...There is also no predictability of action, as the different agencies are free to pick and choose the situations in which they wish to become involved on the basis of their respective mandates, resources, and interests. In every new emergency, no one knows for sure which agency or combination thereof will become involved.In 2005 there was an attempt to fix the problem by giving sectoral responsibilities to different humanitarian agencies, most notably with the UNHCR taking on the responsibility for protection and the management of camps and emergency shelters. The "Forced Migration Review" stated that the "abnegation of responsibility is possible because there is no formal responsibility apportioned to agencies under the Collaborative Response, and thus no accountability when agencies renege on their promises."
